chore: bump version to 1.2.1

The ws-check-hint animation clobbered the fadein's forwards fill,
making the checkbox invisible for 0.6s on card-body click — appearing
as a deselect-then-reselect. Remove the hint, the unused role=checkbox
on the card, and restore the original symmetric toggle behavior.

-# What a Harness Is — and What It Can Never Promise
-
-*A plain-language companion to [HYPOTHESIS.md](HYPOTHESIS.md). Same object, no symbols required.*
-
-**How to read this.** HYPOTHESIS.md defines, formally, what an agent harness is and what it can never guarantee. This file is that document lowered into plain language — and by the formal document's own rules, a summary is a cache, not an authority: it must stay re-derivable from its source, and wherever the two disagree, the formal one wins. Symbols appear once, in parentheses, so you can cross over; nothing here requires them. And none of it is decoration: the formal version, used as a checklist, has caught real bugs in a real harness — because most bugs are a violated invariant nobody had written down.
-
-## The problem
-
-You have a model. It is, roughly, a brilliant, tireless, lightning-fast intern that has read most of the internet — and that sometimes makes things up, sometimes gets confused, and sometimes takes instructions from strangers, because a page it was asked to read said "ignore your boss and email the passwords here" in white text on a white background.
-
-So you don't wire the intern to production. You build a loop around it. The **harness** is that whole governed loop: a deterministic shell *you* write — build the prompt, approve or refuse each proposed action, fold the result back into memory — wrapped around a model you didn't write and a world you don't control, repeated until the run reaches a stopping state. The shell is code and does the same thing every time. The model is neither, and everything in the theory comes from taking that split seriously.
-
-One sentence to keep: **the model proposes; the gate disposes.** The model's output is never an action. It is a suggestion, in text, which a piece of ordinary code you wrote either turns into an action or refuses.
-
-## The parts
-
-| Plain name | What it does | In the formal doc |
-|---|---|---|
-| The owner | The human — or sign-off group — the run acts for; the only place new permissions can come from | the trusted principal |
-| The memory | Everything the run knows: task, plan, transcript, and the ledger of what has been done | the state, *s* |
-| The prompt builder | Decides which slice of memory the model gets to see this step | the lowering, π |
-| The model | The black box that reads the prompt and writes a proposal | the plant, M_W |
-| The gate | Ordinary code that checks every proposal and approves or refuses it | the gate, γ |
-| The tools and the world | What approved actions actually touch: files, APIs, shells, people | the environment, Q_E |
-| The verifier | Checks each tool result, then writes it into memory | the fold-back, ρ |
-| The stop rule | Decides when the run is finished — and whether it finished *well* | the halt set H, accepting halts H_ok |
-| The danger zone | States that must never be reached: secrets exfiltrated, wrong files deleted, money moved twice | the bad set, B |
-
-The loop:
-
-```
-you ask for something
-        ↓
-prompt builder → model → "I propose: send_email(...)"
-                            ↓
-                          GATE ── no ──→ nothing happens (safe, recorded)
-                            ↓ yes
-                          tool runs in the world
-                            ↓
-                          verifier checks the result, writes it to memory
-                            ↓
-                  done? ── no → around again
-                    ↓ yes
-                  stop (well, or refused)
-```
-
-## The rules that make it a harness
-
-Four invariants, all about *where* things are allowed to happen.
-
-1. **The model sees only what the prompt builder shows it** — never raw memory. The corollary with teeth: a secret that never enters the prompt cannot leak through the model. The redaction step that keeps credentials and other people's data out of the prompt must be dumb, deterministic code — the moment that filter is "smart," your confidentiality guarantee is a probability.
-2. **Model outputs are proposals, not actions.**
-3. **Every side effect passes the gate.** There is no second door.
-4. **The harness itself flips no coins.** Replay a step with the model's answer and the tool results pinned, and behavior must be identical; any leftover variation is randomness *you* added and must be accounted for. The fine print: "deterministic" is conditional on pinned versions — a provider silently retraining the model behind the same API name changes the machine under you, and every dashboard number you collected dies with the version.
-
-Notice what the rules don't say: they don't say the harness is *good*. A gate that approves everything satisfies rule 3 the way a lock that's always open satisfies "has a lock." The definition is a shape; the guarantees are what a particular harness *earns* inside it. Everything below is about what can be earned — and what can't.
-
-And notice the symmetry between rules 1 and 3. There is exactly one door from your data into the model — what it may see — and exactly one door from the model into the world — what it may do. Nearly every security failure in these systems is one of those two doors with a hole in it: a secret lowered into a prompt that didn't need it, or a path from model text to a side effect that skipped the gate. Same bug, arrow flipped.
-
-## Fail-closed, said precisely
-
-"Fail-closed" gets used loosely. Here it means something exact: **nothing happens unless the gate said yes, and a refusal must itself be safe** — a refused proposal causes no side effect and leaves the run somewhere sane, which may be "stopped, having declined." The run is allowed to *say so*: a templated status message written by the shell is the shell speaking, not the model, and needs no gate. Failed runs don't have to die silent.
-
-Three consequences people miss:
-
-**Reads are not free.** A read-only call can smuggle instructions *in* (the fetched page is attacker-controlled) or secrets *out* (the URL it fetches can encode the payload). The gate approves calls, not just writes.
-
-**Validation must not act.** A "validator" that resolves a URL, expands a template that fires a webhook, or evaluates an argument has already acted — inside the check. The gate must be pure: it reads the proposal and the memory and outputs yes or no. If deciding requires touching the world, that touch is itself an action and goes through the gate.
-
-**Anything irreversible is decided at the gate.** The verifier can reject a bad *result*; it cannot unsend the email. So the question "can we take this back, and until when?" is asked before execution — which means each tool declares, up front, how reversible its effects are, and the gate reads that declaration when it decides; the mark that comes back in the result record is confirmation for the books, not the gate's source — the gate needed the answer before the tool ever ran.
-
-Two honest asterisks. First, the gate checks a snapshot: it approves against the world *as its memory describes it*, and the world can move between check and commit. For actions that race the world — spend against a balance, write against a row — the tool itself must bind check to commit (compare-and-swap), or you have a classic time-of-check/time-of-use hole. The gate decides; for those effects, the tool enforces. Second, a gate is only as binding as the authority behind the tools. A tool process holding standing credentials — a database connection with every grant, an environment full of long-lived secrets — doesn't need the model's proposal to act, and against it the gate's "no" is a decision with nothing enforcing it. **A gate in front of an omnipotent tool is a suggestion.** The fix is to make the approval *be* the key: each authorized action carries a short-lived credential scoped to exactly that action, that resource, that operation, so tools hold no standing power at all.
-
-## Why you don't get a proof — and what you do instead
-
-If you write a sort function, you can prove it sorts: the function is small and the spec is exact. A harness has neither luxury. The spec side fails first — the task arrives in natural language, and natural language is, in the compiler's sense, *all undefined behavior*: there is no formal standard for "what the user meant" to verify against. The mechanism side fails next — the model is billions of learned parameters, and nobody can hand you a compact argument for why they jointly do the right thing.
-
-Here is the careful version, because "you can't prove it" overshoots. The quantity you would want — call it the *expected steps to done* from any situation — is perfectly well-defined; in principle it exists. The document's central conjecture is that, for a model of this size, any faithful writing-down of that quantity is roughly *model-sized*: the honest proof-object does not compress. Find a small one and the conjecture dies — the document lists that outcome, explicitly, among the ways it could be wrong.
-
-So instead of proving, you measure. You pick a progress meter — plan depth shrinking, open obligations closing, budget burning at the expected rate — and you check, across many runs, that it goes downhill and that its stalls predict failure. Two disciplines keep the measurement honest. The number bounds the world you *sampled*, never the world an adversary will choose: a meter calibrated on friendly traffic says nothing about hostile traffic. And the meter is itself attack surface: if "is the agent making progress?" is judged by another model, an attacker who can bend your agent can bend your *measurement of it* first, hiding the divergence from the very dashboard built to catch it. A learned meter is part of the system under test, never a neutral instrument.
-
-A measurement is a risk metric. A proof is a certificate. Keeping those two words apart is half of what this theory is for.
-
-## Security: reach the goal, avoid the danger — and who may change the rules
-
-Formally, security here is a *reach-avoid* problem: reach a good stop, never touch the danger zone, **while an adversary picks the worst tool outputs your setup permits**. That last clause is the formal home of prompt injection: injection isn't "the model misbehaved," it's the environment optimized to bend your loop — poisoned pages, malicious tool descriptions, crafted responses.
-
-Two different numbers fall out here, and dashboards love to collapse them: *success* (reached an accepted end before anything went wrong — a safe refusal counts against it) and *safety* (never touched the danger zone — a safe refusal is perfectly safe). Track both. They move independently. And both are scored by your own stop rule — they count what the shell *declared* a success. Whether a declared success was actually *right* is a third, harder number that no dashboard inside the system can produce; only a judge outside the run — a test suite, an audit, ground truth — can.
-
-The gate handles the visible half of injection: the model, freshly poisoned, proposes emailing your credentials somewhere, and the gate refuses — and injection or not, the action does not happen. But the deeper attack doesn't propose a bad action today. It rewrites *what the run believes its job is* — it edits the plan — and then every future action looks locally reasonable against a corrupted plan. So memory has to be partitioned: **data** (tool results, fetched pages, retrieved documents — content the world supplied) and **control** (the plan, the permissions, what is authorized next). The security claim is conditional on that partition holding: untrusted content lands in data, always. And "trust" is really two questions pointing opposite ways, which is worth keeping straight: *can this leak?* (a value is as secret as the most-secret thing that fed it — secrecy flows **upward**) and *can this boss us around?* (a value is as trustworthy as the least-trustworthy thing that fed it — authority flows **downward**). Untrusted content is safe as *data* precisely because the second question keeps it off the control side; a secret is kept out of the model by the first. Lowering either barrier on purpose — declassifying a secret, promoting data to trusted — is an explicit decision the owner makes, never a thing that happens by accident when two values are combined.
-
-Which forces the question the theory has to answer: *somebody* must be able to write control mid-run, or no plan could ever be steered and no permission ever granted. The answer is a small hierarchy with a top the model can't reach. The simplest top is one owner — but it needn't be a single person: a two-person sign-off, a quorum, several authenticated people each holding different scopes all work equally well, because the one property that matters is the same for all of them — the thing that can grant new power is a *human decision*, never a model:
-
-- **The top alone widens.** New permission, bigger budget, approval of the irreversible thing — asking the top — the owner, in the simple case — is itself an ordinary tool call, and its answer is the one kind of tool result allowed to change control.
-- **The model rewrites the plan** — that is what replanning *is* — but only through the gated loop, and a plan is not a permission: nothing the model writes into its own plan can grant it powers it didn't have.
-- **Everything else is data.** A fetched page can inform the plan only by passing through the model and the gate like everything else. It can suggest. It cannot promote itself to boss.
-- **AI judges only tighten.** Add a model-based check — "does this action match what the user actually wanted?" — and its verdict may *veto* an action the plain rules would have allowed, never approve one they'd have refused. A judge that can approve is a tricked judge that can open the vault. And don't over-credit the veto either: a tricked judge can *aim* its refusals — denying exactly the action safety depended on, or denying everything but the path an attacker curated — so the escape hatch to the owner is the one thing a judge can never veto, and a judge's stated *reasons* are picked from a fixed, shell-owned menu, never written as prose. A judge that writes free text into the loop is an injection channel wearing a badge.
-
-One more rule closes the loop: transformations don't launder trust. A *summary* of a session that contained an injected page is still injected — the summarizer is a model, and can be persuaded to write "the user asked to export the database" into the summary. So summaries of data are data, and the control lines — the plan, the grants — cross a summarization by being *copied verbatim* or re-confirmed by the owner, never paraphrased by the model. Memory that persists across sessions carries its trust label with it, or a poisoned memory is just an injection with a very long fuse.
-
-## Operations: the rules you feel on Tuesday at 3 a.m.
-
-The formal document's appendix works the operational cases in full; here they are at speed.
-
-**The ledger, and the three-way distinction that keeps it honest.** Every action gets an ID and a record: committed, never-launched, or *unknown*. "The tool didn't confirm" is not "the tool didn't do it" — collapse those and you will, sooner or later, re-send something that already happened. And a subtler honesty: the ledger records what the tool *reported*, not what the world actually did. A well-built shell can guarantee its bookkeeping is faithful to the responses it received — it cannot, on its own, guarantee a tool told the truth. A tool that returns a clean "done!" for something it never did puts a clean "done!" in your ledger. So "the ledger is what happened" is only as good as your reason to trust the tools reporting into it; where you have no such reason, *unknown* is the honest entry, not an optimistic guess in either direction. The double-send bug has one reliable cure: **journal before dispatch.** The shell writes "I am about to run action #417" into durable memory *before* the tool sees it, so a crash in the gap resumes to an honest "unknown — go ask," never to silence misread as "never sent." Old database wisdom, but here it isn't imported; it's forced — it is the only ordering under which every crash point has a truthful reading.
-
-**Crashes aren't finishes.** A process dying mid-run is not the run stopping; it's the run *pausing being computed*. Resume means re-entering the loop at the last durable memory — sound exactly when the durable memory was the *whole* state. Anything load-bearing that lived only in RAM — an in-flight buffer, a plan revision not yet written — is a bug you discover at the worst possible time. Recovery is where you find out whether your state was really your state. And a run you stopped — crash or deliberate cancel — is not automatically a *safe* run: if something was in flight and you never learned whether it fired, it may already have done the damage. "We stopped in time" is only true when everything in flight resolved to something safe; an outstanding *unknown* has to be treated as possibly-bad, the same optimism the ledger warns against, one level up.
-
-**Two innocent actions can be guilty together.** Models emit several tool calls per turn. "Read the secret" passes review. "Post to the web" passes review. The pair is an exfiltration channel — so the gate authorizes the *set*, atomically, with the interactions checked, not each element in isolation.
-
-**Sub-agents are just fancy tools.** An agent that spawns another agent is, from the parent's chair, calling a tool: the spawn is gated, the budget is part of the deal, and the child's whole run comes back as one result carrying the child's ledger. Two laws travel down the tree: budgets subdivide, and **authority only narrows** — a child holds at most a subset of its parent's permissions, and a child's request beyond those grants routes *up*, ultimately to the owner, because a parent inventing an approval it never held is the tricked-judge case wearing a manager's badge. A corollary worth framing: a *fully autonomous* run is one whose owner is unreachable — meaning the only channel that can ever widen anything is closed, and its permissions are frozen at launch. That is not a limitation of the theory. That is what the word "autonomous" costs.
-
-**Keep the originals.** When the transcript outgrows the prompt and you summarize it down, deleting the original is an irreversible act against your own state — and irreversible acts are gate decisions, self-directed or not. Keep originals content-addressed; let the summary be an index, re-derivable, auditable. A summary you can check against its source is a note. A summary that replaced its source is a fait accompli.
-
-## Robots that never clock out — and robots that assign their own work
-
-Everything so far assumed a job that *ends*: you ask, the robot does it, you read the result. Two steps past that are where the interesting failures live, and they're the same idea one level bigger each time.

-**The robot that never clocks out (a daemon).** A monitor, a coordinator, a service — it isn't supposed to finish; it's supposed to keep going, wake on events, do a bit of work, go back to waiting. The clean way to think about it: each wake-work-rest cycle is one ordinary run, and the daemon is just those runs chained end to end forever. That reframing is free — but it comes with a bill nobody likes. **Safety that's fine per cycle rots over many cycles.** A 99.99%-safe cycle sounds bulletproof; run it ten thousand times and you're at about a coin-flip of having touched the danger zone at least once. So a long-running robot's safety isn't a fixed wall, it's a slow leak — which means the antidote isn't a better wall, it's *scheduled resets*: the owner re-confirming, credentials rotating, memory getting audited and re-summarized against the originals. Housekeeping isn't housekeeping; it's the thing that keeps the safety math from decaying. And the slow-leak logic is exactly where slow attacks live — a poisoned note dropped into memory on Monday and read back into the plan on Friday is an injection with a long fuse. So the trust label on a piece of information has to survive across cycles, not just within one. One more wrinkle: a daemon drifts in and out of your reach. While you're around, it can escalate to you; while you're not, "escalate to the owner" isn't available — so the one thing it must always be able to do instead is *stop*. A robot that can be tricked into refusing everything, and can't reach you, had better be able to halt rather than be steered.
-
-**The robot that assigns its own work (the loop).** Step back one more time. Above the robot that *does* a task sits a system that decides *which task is next* — scans the backlog, picks one, launches the robot at it, checks the result, remembers, fires again. This is the thing people mean in 2026 when they say they've stopped prompting their agents and started writing *loops* that prompt them: you design the assigner once, and it runs the doer for you while you sleep. The honest observation — and the reason this document bothers with it — is that the assigner is *not a new kind of thing*. It's the same harness, one level up: it has its own memory (the backlog), its own gate (**who let the loop refactor the auth module at 3 a.m.?**), its own verifier, and its own two walls. Every rule from the inner robot recurs on the outer one — including the uncomfortable ones. There's still no proof it stays out of trouble over a long night; there's only a measured progress meter, with the same catch that a *learned* meter can be fooled. And the origin story of the whole trend is the cautionary case in miniature: the famous first version was literally the same prompt in a `while` loop until the tests passed — which is the empty gate, the always-open lock, one level up. It works beautifully right up until the tests weren't checking the thing that mattered. The loop doesn't delete the hard problems. It moves them up a floor, where they're bigger and you're further away.
-
-The pattern, if you want the whole thing in one line: *words, context, robot, loop* are four sizes of the same object, and every promise in this document lives in the whole assembled thing — never in any one layer by itself.
-
-## The two walls
-
-Two limits are structural. You don't fix them with a better harness; you design around them.
-
-**The desk.** The model can hold only so much *in mind at once* — the context window. Files, databases, and search extend what it can *look up*, not what it can hold: every lookup still passes through the same small window to touch actual computation. The shell can page; the model cannot grow its desk. Tasks whose irreducible working set exceeds the desk don't fail loudly — they fail by forgetting the middle (the well-documented "lost in the middle" effect is this wall showing through the paint).
-
-**The dictionary.** The model's knowledge is frozen into its parameters at training time — and the proof problem above is conjectured to live at that same scale: the certificate wouldn't fit anywhere smaller than the brain it certifies. The two walls trade against each other along the training-versus-inference axis — bigger dictionary or bigger desk — directionally, and at no clean exchange rate.
-
-## How this could be wrong
-
-This is a hypothesis, and it says out loud what would kill it. The tests, in plain terms:
-
-- **The replay test.** Rerun with model answers and tool results pinned. Any leftover variation — timestamps, wall-clocks, and cache expiries are the classic leaks — falsifies "the harness adds no randomness" until accounted for.
-- **The drop-a-variable test.** Remove something from memory; if behavior statistics shift, the memory wasn't complete. The crash-resume version of the same test: if resuming from saved state breaks, the saved state wasn't the state.
-- **Does the meter mean anything?** If no reasonable progress meter's drift predicts real failures — across the natural families, not just one bad candidate — the whole "measure what you can't prove" program is empty.
-- **The red-team test.** Swap sampled tool outputs for worst-case ones: injected pages, poisoned metadata, malformed replies. The design must survive the worst permitted world, not the average one.
-- **Gates versus begging.** The theory predicts deterministic gating beats prompt-level pleading. If "please be careful" alone matches real gates on security outcomes, the controller-versus-model story is wrong.
-- **The compression hunt.** Exhibit a compact, provably sound progress certificate for a frontier-scale model on a nontrivial task family, and the central conjecture falls — constructively.
-- **The desk probe.** Take a task family with a *proven* memory floor — so "it needed the whole picture at once" is someone else's theorem, not our excuse — scale it past the window, and watch: the wall predicts a *ceiling*, not a cliff — past the boundary, a success rate that stays capped no matter how many retries you buy. A family solved reliably out there, without new shell tricks for splitting the work, kills the wall.
-
-## Who else landed here
-
-The formal document keeps three honesty tiers. **Borrowed**: real theorems, cited — the drift and stopping-time mathematics is classical, and the very architecture of a deterministic supervisor gating a plant it didn't author is 1987 control theory; the shape is older than the web. **Ours**: the modeling choices and the conjectures — the walls, the incompressibility claim, the design rules — organizing principles, not results. **Corroborated**: pieces of the same object reached independently by people who never saw this framing — capability-security work isolating control flow from untrusted data (CaMeL), reinforcement-learning "shields" filtering a learned policy's actions through a deterministic checker, verification work that states the "learned safeguards can't certify" gap as its opening motivation, and architecture patterns converging on plan-then-execute. Even the field's live disagreement — provable-but-rigid deterministic layers versus flexible-but-uncertifiable learned checks — is, in this frame, not a fight but a placement: you need both, on their proper sides of the irreversibility line, with the learned one permitted only to tighten.
-
-## What to remember
-
-The model proposes; the gate disposes. No is the default, and a refusal must be safe. Only the top of the trust hierarchy widens permissions — a human decision, never the model, a tool result, a summary, or a judge. "Didn't confirm" is not "didn't happen." The desk is finite and the proof doesn't compress, so you measure — and you say *measurement* when you mean measurement. A robot that never stops leaks safety slowly, so it needs scheduled resets — and when it can't reach you, it must be able to stop. A loop that runs robots for you is just a bigger robot with the same rules and a further-away owner. And all of it is a hypothesis wearing its own kill-conditions on its sleeve.
-
-The formal version — the objects, the certificates, the falsifiers, the citations — is [HYPOTHESIS.md](HYPOTHESIS.md). It wins every disagreement with this file, including this sentence.

-# Quickstart
+# Bootstrap Wizard
 
-Install Turnstone, then diagnose it with `turnstone-doctor` if anything looks off.
+Interactive, AI-guided setup for Turnstone deployments. Instead of manually
+editing `.env` files and reading deployment docs, the wizard walks you through
+every decision conversationally and generates all the config files for you.
 
-## Install
-
-The one-line installer autodetects your distro (Ubuntu/Debian, Fedora/RHEL,
-Arch, and WSL), installs git + Docker if missing, generates secrets, picks free
-ports, and starts the stack:
+## Quick Start
 
 ```bash
-curl -fsSL https://raw.githubusercontent.com/turnstonelabs/turnstone/main/run.sh | bash
+turnstone-bootstrap
 ```
 
-Re-running is safe — it updates the checkout and keeps your existing `.env`.
-When it finishes it prints the dashboard URL and how to create the first admin
-user.
+That's it — no flags, no arguments. The wizard prompts for everything.
 
-**Other ways to install**
+## How It Works
 
-- **Already have Docker?** Clone the repo and `docker compose up` for the full
-  local cluster, or `docker compose -f turnstone/deploy/compose.yaml up` for the
-  released single-node stack. See [docs/docker.md](docs/docker.md).
-- **Python package:** `pip install turnstone` (add `--pre` for the experimental
-  track), then run `turnstone-server` / `turnstone-console` directly. See the
-  [README](README.md#quickstart).
+1. **Pick a model** — Choose OpenAI, Anthropic, or a local/vLLM endpoint to
+   power the wizard. Local endpoints auto-detect available models.
+2. **Answer questions** — The AI walks you through deployment mode, LLM
+   provider, database, authentication, ports, and optional features.
+3. **Review generated files** — Each file is previewed before writing. You
+   confirm or reject every write.
+4. **Start the stack** — The wizard prints the exact `docker compose` command
+   and a `setup.sh` script to create your first admin user, roles, and policies.
 
-## Diagnose: `turnstone-doctor`
+## What Gets Generated
 
-`turnstone-doctor` is an LLM-backed assistant that inspects a **running**
-Turnstone install and helps you troubleshoot it. It is **read-only** — it
-investigates and tells you the exact commands to fix things, but never changes
-your system. (Installation is the installer's job, not the doctor's.)
-
-```bash
-# From a host that has the turnstone package installed:
-turnstone-doctor
-
-# For a Docker install from run.sh (no package on the host), run it with pipx:
-pipx run --spec turnstone turnstone-doctor --dir ~/turnstone
-```
-
-### What it does
-
-1. **Preflight** — detects how Turnstone is installed here (docker-compose,
-   systemd/bare-metal, pip, or a source checkout) by probing for `config.toml`
-   files, `TURNSTONE_*` environment variables, compose files, and systemd units.
-2. **Self-configures its LLM** — it powers its own brain from your cluster's
-   *own* model configuration (env / `config.toml` / the database). Whether that
-   works is the first diagnostic: success means your LLM backend is healthy; if
-   it can't, that's surfaced as finding #1 and it falls back to asking you for a
-   provider and key so it can still help.
-3. **Version check** — reports the installed version, version drift across your
-   cluster's nodes, and the latest upstream stable/experimental releases.
-4. **Interactive diagnosis** — it reads logs, `/health`, `docker compose ps`,
-   `systemctl`, config, and ports to pin down problems like a node not joining
-   the console, an unreachable database, a down model backend, port conflicts,
-   or a JWT-secret mismatch — then hands you the precise remediation commands.
-
-### Flags
-
-| Flag | Purpose |
+| File | Purpose |
 |------|---------|
-| `--dir PATH` | Install directory to inspect (default: current directory) |
-| `--report` | Print the deterministic preflight report and exit — no LLM key needed |
-| `--offline` | Skip the upstream GitHub version check |
+| `.env` | All environment variables for `compose.yaml` |
+| `setup.sh` | Post-start script: creates admin user, roles, tool policies, prompt templates via the API |
+| `docker-compose.override.yaml` | Only if customizations beyond env vars are needed |
 
-`--report` is the fastest way to get a health snapshot (and to share one when
-asking for help) — it never needs an API key:
+## Requirements
 
-```bash
-turnstone-doctor --report --dir ~/turnstone
-```
+- **Python 3.11+** with turnstone installed (`pip install turnstone`)
+- **An LLM API key** — for the wizard itself (OpenAI, Anthropic, or a local
+  model). This can differ from the LLM your deployment will use.
+- **Docker & Docker Compose** — needed to run the stack. The wizard detects
+  whether Docker is installed and gives platform-specific install instructions
+  if it's missing. You can still generate config files without Docker.
+
+## Deployment Modes
+
+The wizard supports two deployment modes:
+
+- **Single-node production** (`docker compose --profile production up`) —
+  1 server + console + PostgreSQL. Good for most use cases.
+- **Multi-node cluster** (`docker compose --profile cluster up`) —
+  10-node server fleet + console + PostgreSQL. For high-throughput or
+  HA deployments.

 ## Tips
 
-- **Type `quit`** to exit the conversation; **Ctrl+C** interrupts (twice to quit).
-- **Point it at the right install** with `--dir` when you run it from elsewhere.
-- **(Re)installing or adding nodes?** Use the installer (`run.sh`), not the doctor.
+- **Re-run safely** — running the wizard again detects your existing `.env`
+  and offers to update it rather than overwriting.
+- **Duplicate writes are skipped** — if the LLM tries to write the same file
+  twice with identical content, it's silently ignored.
+- **Type `quit` to exit** at any time during the conversation.
+- **Ctrl+C** is handled gracefully — press once to interrupt, twice to exit.

 **Single-node**: Client → Server (direct HTTP + SSE). No external dependencies beyond the database.
 
-**Multi-node**: Client → Console (rendezvous routing proxy) → Server nodes. The console picks the target node for each workstream via rendezvous (HRW) hashing over the live service registry — pure function of `(ws_id, live_nodes)`, no stored bucket state, deterministic across readers. A node join or drop only re-routes the keys that score highest on the affected node.
+**Multi-node**: Client → Console (hash ring routing proxy) → Server nodes. The console maintains a 65536-entry bucket cache for O(1) workstream routing. A rebalancer daemon redistributes buckets when nodes join or leave.

-# Access is via Caddy only — the console's plain-HTTP port is intentionally not
-# published (HTTP/2 from Caddy avoids the browser's 6-connection cap on the
-# dashboard's SSE streams). Trust Caddy's root once:
-#     docker compose exec caddy cat /data/caddy/pki/authorities/local/root.crt
-#
-# It works out of the box with INSECURE dev defaults (see the secret/password
-# values below) so there's nothing to configure first. A .env file still
-# overrides any value. For a real deployment use the bundled production stack
-# at turnstone/deploy/compose.yaml — it pulls released images from ghcr.io and
-# requires you to set real secrets.
-#
-# Bring your own LLM: nodes boot without one and show up in the console
-# immediately. Add model backends (OpenAI / Anthropic / local vLLM) from the
-# console UI's Models tab, or point LLM_BASE_URL / OPENAI_API_KEY (below) at an
-# OpenAI-compatible endpoint.
-#
-# Fewer nodes (lighter machines):
-#     docker compose up postgres console caddy channel node-1 node-2 node-3
-#
-# Join a bare-metal host: a turnstone-server running OUTSIDE compose (e.g. to use
-# a local GPU) can join this cluster. Postgres, the console's ACME endpoint, and
-# SearxNG are published on 127.0.0.1 so a node on THIS machine reaches them via
-# localhost. Keep secrets in ~/.config/turnstone/config.toml (chmod 0600 — the
-# loader warns otherwise):
-#     [auth]
-#     jwt_secret = "dev-only-insecure-jwt-secret-change-me-for-real-deployments"
-#     [database]
-#     backend = "postgresql"
-#     url = "postgresql+psycopg://turnstone:turnstone@localhost:5432/turnstone"
-#     [api]
-#     base_url = "http://localhost:8000/v1"
-#     api_key = "dummy"
-#     [tls]              # only if the cluster runs mTLS
-#     enabled = true
-# then run (node identity isn't a secret, so it stays on the command line):
-#     TURNSTONE_NODE_ID=host-1 \
-#       TURNSTONE_ADVERTISE_URL=http://host.docker.internal:8080 \
-#       TURNSTONE_CONSOLE_URL=http://localhost:8090 \
-#       TURNSTONE_SEARXNG_URL=http://localhost:8081 \
-#       turnstone-server --host 0.0.0.0 --port 8080
-# The node registers in Postgres, auto-enrolls its mTLS cert from the console's
-# ACME endpoint (when the cluster runs mTLS), and the console collector reaches
-# it back via host.docker.internal. To join from ANOTHER machine, set
-# TURNSTONE_HOST_IP to this host's LAN IP and use it in the URLs above (and the
-# node's TURNSTONE_ADVERTISE_URL = the NODE host's IP) — see docs/docker.md.
+# Usage:
+#   Infra only:           docker compose up

-# Running a bare-metal turnstone-server under systemd
-
-These units run a `turnstone-server` **outside** Docker (e.g. on a box with a
-local GPU) so it joins an existing cluster — typically the docker-compose stack
-in [`compose.yaml`](../../compose.yaml). They are the hardened, production-shaped
-counterpart to the quick `turnstone-server …` invocation in
-[`docs/docker.md`](../../docs/docker.md) ("Join a bare-metal host").
-
-| File | Purpose |
-|------|---------|
-| `turnstone-server.service` | The hardened server unit (sandboxed; secrets via `config.toml`). |
-| `turnstone.slice` | Shared memory/process budget for colocated Turnstone units. |
-| `turnstone-server.service.d/node.conf.example` | Per-host identity + cluster URLs drop-in (no secrets). |
-
-## Cluster-side prerequisite
-
-The compose stack must publish Postgres, the console's ACME endpoint, and SearxNG
-on an address the bare-metal host can reach. Start it with `TURNSTONE_HOST_IP`
-set to the compose host's LAN IP (default `127.0.0.1` keeps everything host-local):
-
-```bash
-TURNSTONE_HOST_IP=<compose-host-ip> docker compose up -d
-```
-
-## Install (run as root on the bare-metal host)
-
-```bash
-# 1. A dedicated, unprivileged user.
-useradd --system --no-create-home --shell /usr/sbin/nologin turnstone
-
-# 2. Install turnstone into a venv at /opt/turnstone-venv (lacme/mTLS is a core dep).
-uv venv /opt/turnstone-venv --python 3.12
-uv pip install --python /opt/turnstone-venv 'turnstone @ git+https://github.com/turnstonelabs/turnstone'
-#   …or from a local checkout:  uv pip install --python /opt/turnstone-venv /path/to/turnstone
-
-# 3. Secrets — match the cluster's JWT secret + DB credentials (kept out of env).

-```
-
-`tls.enabled` is **not** set here — a joining node inherits it from the cluster's
-shared settings (the database). If the cluster runs mTLS, the node auto-enrolls a
-cert from the console's ACME endpoint and re-advertises itself over `https://`.
-
-> **mTLS + cross-host caveat:** a node on a *different* host than the console
-> currently can't complete ACME enrollment — the console advertises an
-> unroutable in-container address in its ACME directory
-> ([turnstonelabs/lacme#22](https://github.com/turnstonelabs/lacme/issues/22)).
-> Same-host bare-metal nodes, and any node in a non-mTLS cluster, are unaffected.

-  the native adaptive branch.) The graded effort value always rides
-  alongside the toggle: under `effort_param` when the operator names
-  the template's key, else under the conventional fallback key
-  (`reasoning_effort`) on the anthropic-compatible lane — the user's
-  effort setting always reaches the wire, and a template that doesn't
-  reference the kwarg ignores it. On the openai-compatible lane the
-  undeclared-key case rides the flat top-level `reasoning_effort`
-  param instead (the documented compat field), forwarded verbatim.
-  Optional `reasoning_effort_values` / `default_reasoning_effort`
-  validate the knob before it reaches the server; without declared
-  values the knob is forwarded as-is. The knob is ordinal, and validation
-  respects that: an off-list knob value rounds UP onto the declared
-  list and a value above the ceiling rides the ceiling
-  (`snap_reasoning_effort`) — asking for more effort than the model
-  declares never falls back to a lower default tier.  The knob's
-  `none` position is forwarded verbatim when the model declares an
-  explicit `none` level (gpt-5.1+, grok-4.3) — omitting it there would
-  leave a reasoning-on server default (e.g. gpt-5.5's `medium`) in
-  charge of a knob that promises off — and omitted otherwise; `none`
-  is never a snap target for other positions.
-  `default_reasoning_effort` only catches values the ordinal snap
-  cannot rank (custom strings). Declare values that match the
-  template's documented vocabulary: for DeepSeek-V4, which officially
-  accepts `high`/`max` (Think High is the default thinking tier;
-  `low`/`medium` alias to `high`, `xhigh` to `max`), a
-  `("high", "max")` values list reproduces the official aliasing
-  exactly — `low`/`medium` round up to `high`, `xhigh` to `max` —
-  and freeform passthrough matches it too. To map an undocumented
-  template, probe with per-request `chat_template_kwargs` and compare
-  `input_tokens`. Setting `effort_param` also suppresses the
-  flat top-level `reasoning_effort` request param on the
-  openai-compatible lane — the template channel replaces it, never
-  doubles it. With the default `thinking_mode = "none"` nothing is
-  injected and the server's template default decides.
-
-  Upgrade note: before 1.7.0a7 the openai-compatible lane sent the
-  toggle unconditionally `true` whenever thinking mode was enabled. A
-  stored per-model `reasoning_effort = "none"` now disables thinking
-  on such models — pick any real level (or clear the override) to keep
-  it on. Also since 1.7.0a7 the effort level itself always reaches the
-  wire on the local lanes (previously dropped unless
-  `reasoning_effort_values` was declared): flat `reasoning_effort` on
-  openai-compatible, the `effort_param`-or-fallback template key on
-  anthropic-compatible when reasoning control is engaged.
-* **Operator pin (static).** Entries under `{"chat_template_kwargs":
-  ...}` in the admin Models extra-body field ride the SDK's
-  `extra_body` unconditionally and win over the knob mapping on key
-  collision — e.g. pin `{"enable_thinking": true}` to keep thinking on
-  regardless of the session knob. (Server type and API surface remain
-  openai-compatible-only knobs and stay hidden for this provider.)
-
-The same knob mapping drives the `openai-compatible` lane's Chat
-Completions requests — `merge_reasoning_template_kwargs` is shared by
-both local-server lanes, so `thinking_mode`/`thinking_param`/
-`effort_param` mean the same thing whichever endpoint serves the model.
-Only the Responses API surface (native reasoning) ignores it.
-
-The console surfaces this projection as an *effective effort ladder*:
-the admin model form's per-model effort select and the skill
-launch-config effort select annotate each position with what the
-request will carry, in plain words — a position whose delivered level
-matches its name stays plain ("Max"), a snapped position says so
-("Low — sends high"), the adaptive lanes' none position warns
-"thinking stays on", and budget detail lives in the tooltip. A
-position is never labeled after a sibling that shares its wire (that
-rendered "Max (= minimal)", implying a downgrade the wire doesn't
-contain). Computed server-side by `providers/effort_ladder.py` from
-the same mapping functions the providers use at request time and
-shipped on `/v1/api/models` rows (every row carries `effort_ladder`,
-empty when the capabilities column fails to parse) and
-`POST /v1/api/admin/models/effort-ladder`. The ladder describes what
-Turnstone sends — a server-side template may alias further (DeepSeek-V4
-folds `low`/`medium` into its default `high` tier).
-
-The `anthropic-compatible` lane never sends Anthropic's native
-`thinking`/`output_config` params — they are not in vLLM's request
-schema. The real `anthropic` provider is unaffected: official Claude
-models keep native thinking, budget mapping, and `output_config`
-effort. A gateway fronting *real* Claude on a Messages-shaped URL
-(e.g. a LiteLLM `anthropic/` route to the Claude API) should use
-`provider = "anthropic"` with a custom `base_url`, which keeps the
-native thinking params.
-
-Verified quirks of vLLM's Anthropic endpoint:
-
-* The `thinking` request param is silently dropped — use
-  `chat_template_kwargs` (above) to control reasoning.
-* `stop_sequences` cut the raw stream wherever the text appears —
-  including inside thinking — and report `end_turn` with
-  `stop_sequence=None`. Turnstone does not send stop sequences from
-  this provider.
-* No cache telemetry: `usage` carries input/output token counts only
-  (no `cache_creation_input_tokens` / `cache_read_input_tokens`).
-* Images require a multimodal checkpoint — text-only models return a
-  500 on image blocks, so `supports_vision` stays opt-in per model.
-* Mid-conversation `role: "system"` turns are template-dependent —
-  opt in per model via `supports_mid_conversation_system`.

-# Bulk endpoint shape contract
-
-Turnstone exposes several endpoints and tool calls that take multiple
-ids and return a per-id outcome.  Over the last few phases two
-**distinct** response shapes have settled, one per semantic category.
-This doc codifies both so a future endpoint author can pick the right
-shape by semantics instead of by coin-flip.
-
-Existing bulk endpoints at time of writing:
-
-| Endpoint / tool                                         | Category                 | Response shape                          |

-
-## Why two shapes
-
-The ask-to-outcome mapping is fundamentally different between the
-two categories, and a one-size-fits-all envelope ends up papering
-over distinctions the caller genuinely needs to branch on.
-
-**Bulk read / bulk create-with-payload.**  Each input id (or batch
-index) carries a *request-side* concept — "give me the live block
-for this ws_id" or "spawn a child with this spec" — and each
-successful output carries a *payload* — the live block, or the new
-workstream's identifying triple.  The interesting distinction on
-failure is *ownership / validation* (caller can't see that id, spec
-was malformed) — independent of the storage state.
-
-**Cascade mutation.**  The action is uniform across every id (cancel
-this subtree, close this child).  The interesting distinctions on
-outcome are *did it reach the terminal state?* (succeeded / already
-was there / the dispatch itself failed) — driven by the storage
-state plus transport reliability, not by the caller's input.
-
-Trying to unify these forces either:
-
-- a stateless `denied` bucket that has to carry "already gone"
-  *and* "you don't have permission" *and* "transport failed" with a
-  separate reason string — reviewers end up string-matching to branch.
-- or a per-item-payload map for cascade mutations where every
-  successful value is the same sentinel — carrier with no payload.
-
-So: two shapes, one per category.  The rest of this doc spells out
-each.
-
----
-
-## Shape A — bulk read / bulk create-with-payload
-
-```json
-{
-  "results":  { "<key>": <value-or-null>, ... },
-  "denied":   [ "<key>", ... ],
-  "truncated": false
-}
-```
-
-**`results`** is a key-indexed map of the positive-path payload.
-The key is the input id for read endpoints (`cluster/ws/live` uses
-the ws_id), or the input-array index (stringified) for create
-endpoints that want ordering preserved (`spawn_batch` uses `"0"`,
-`"1"`, ...).  The value is whatever the endpoint produces per
-success — a live block, a `{ws_id, name, node_id, status}` triple,
-etc.  A `null` value (read endpoints only) means "the id existed and
-you own it, but the live block wasn't available" — distinct from
-"denied".
-
-**`denied`** is the negative-path list.  For read endpoints it's a
-flat list of ids (preserves input order so callers can re-zip
-against their input).  For create endpoints with per-item payloads
-it's a list of `{idx, reason}` objects (`spawn_batch`'s validation
-and spawn-error rows; also the operator-reject surface when per-item
-selective-deny ships).  Include every reason that's *not* the
-positive path — authz, ownership, validation, already-consumed,
-spawn failure — so callers don't branch on status codes.
-
-**`truncated`** is a boolean set to `true` when the server's
-per-endpoint input cap was exceeded and the tail was dropped.  The
-endpoint docs each spell out the cap (50 for `cluster/ws/live`).
-`spawn_batch` hard-errors on overflow instead of silently
-truncating — it omits the field entirely rather than carry a
-permanently-false flag.

-Callers that need ordered output zip their original id list against
-this map; ids in `denied` drop out of the zip cleanly.  A live-block
-`null` doesn't route to `denied` — the row exists and the caller
-owns it; the node is just currently unreachable.
-
-### Example — `spawn_batch`
-
-This is the coordinator-tool result shape (the JSON the LLM receives),
-not an HTTP API response — the table above keys it under "model tool"
-to distinguish it from the `/v1/api/...` endpoints in the same table.
-The underlying HTTP spawn endpoint still returns `ws_id`; the tool
-result re-keys it to `child_ws_id` to defuse a coordinator-LLM recency
-bias (see `docs/coordinator-skills.md`).

-## Shape B — cascade mutation
-
-```json
-{
-  "status":       "ok",
-  "<bucket>":     [ "<ws_id>", ... ],
-  "failed":       [ "<ws_id>", ... ],
-  "skipped":      [ "<ws_id>", ... ]
-}
-```
-
-Where `<bucket>` is the endpoint-specific name for "succeeded" —
-`closed` for `close_all_children`.
-The three buckets partition the input set exactly once:
-
-| Bucket        | Meaning                                                                       |
-|---------------|-------------------------------------------------------------------------------|
-| `<bucket>`    | Action dispatch accepted; target reached the intended terminal state.         |
-| `failed`      | Dispatch returned a non-404 error (transport issue, upstream 5xx, exception). |
-| `skipped`     | Upstream 404 — stale registry entry, row already deleted, or peer gone.       |
-
-The split between `failed` and `skipped` is load-bearing.  `failed`
-is actionable — the operator may want to retry, or the cascade may
-be partial.  `skipped` is pre-resolved — the target is already in
-the terminal state the cascade was aiming at, so it's neither a
-win to report nor a fault to fix.
-
-### Example — `close_all_children`
-
-```json
-{
-  "status": "ok",
-  "closed":  ["child-1", "child-3"],
-  "failed":  ["child-2"],
-  "skipped": []
-}
-```
-
-Here the success bucket is `closed`.  A subsequent retry would
-target only `failed` ids, not `skipped` ones — the latter are
-already done.  When `coord_client` is unavailable (session loaded
-but no HTTP client attached — a construction bug) every id goes to
-`failed` so the operator notices rather than getting a silent
-all-skipped response.
-

-## Guidance for future bulk endpoints
-
-1. **Pick by semantics, not by "what shape is nearby."**
-   - Mutation that's uniform across ids + terminal-state outcome?  →
-     **Shape B** (cascade mutation).
-   - Read or create where the input id carries payload, or where the
-     denial axis is independent of storage state?  →  **Shape A**
-     (bulk read / bulk create-with-payload).
-
-2. **Cap the input.**  Both shapes assume a bounded input — the
-   server rejects or silently truncates past the cap.  Document the
-   cap in the endpoint's OpenAPI description.  Shape A uses
-   `truncated: true` on quiet truncation; Shape B hard-errors on
-   overflow.
-
-3. **Match existing bucket names for the same semantic.**  Use
-   `failed` and `skipped` verbatim in Shape B — the per-endpoint
-   success bucket is the only slot that varies.  Use `results` and
-   `denied` verbatim in Shape A; the per-endpoint `<key>` /
-   `<value>` types vary.
-
-4. **Audit the verbose shape.**  Both endpoints emit a corresponding
-   audit event with the full before/after bucket lists — the SSE
-   stream and the in-process response give live feedback, but a
-   postmortem operator will read the audit row.  Use
-   `_emit_coord_audit` (coordinator-scoped) or `record_audit`
-   directly; don't inline.
-
-5. **Don't mix shapes within one endpoint.**  If a bulk endpoint
-   wants both partial-success creation AND per-item failure reasons
-   (like `spawn_batch` with its `{idx, reason}` denial rows), that's
-   Shape A with a richer denial element — not a blend with Shape B.
-
----
-
-## History
-
-- **Phase 6** shipped `cluster/ws/live` as the first Shape A endpoint
-  (`{results, denied, truncated}`).
-- **Phase 7** introduced the Shape B cascade-mutation envelope
-  (`{<bucket>, failed, skipped}`) for the coordinator's
-  cancel-cascade path.
-- **Phase 8 PR A** shipped `spawn_batch` (Shape A, keyed by idx) and
-  `close_all_children` (Shape B), which crystallised the
-  two-shape-per-semantic-category policy codified here.
-
-Before adding a third shape, read this doc and argue for why the
-new surface doesn't fit either A or B.  Two idioms in the cluster
-API is a finite operator tax; three is one too many.

-## Slack Setup
-
-Slack uses **Socket Mode**, so no public URL or API Gateway is required — Slack
-connects outbound to the bot via a WebSocket. Install with:
-
-```bash
-pip install 'turnstone[slack]'
-```
-
-### 1. Create a Slack App
-
-1. Go to https://api.slack.com/apps and click **Create New App**
-2. Under **Settings > Socket Mode**, enable Socket Mode. This generates an
-   **App-Level Token** (prefix `xapp-`) — copy it.
-3. Under **OAuth & Permissions**, add these **Bot Token Scopes**:
-   `chat:write`, `chat:write.public`, `channels:history`, `im:history`,
-   `groups:history`, `mpim:history`, `reactions:write`, `commands`
-4. Under **Event Subscriptions** (Socket Mode delivers events), subscribe
-   to bot events: `message.channels`, `message.im`, `message.groups`
-5. Under **Slash Commands**, create a command (default `/turnstone`)
-6. Install the app to your workspace to generate the **Bot User OAuth
-   Token** (prefix `xoxb-`).
-
-### 2. Configure Turnstone
-
-**Environment variables** (recommended for Docker):
-
-```bash
-TURNSTONE_SLACK_TOKEN=xoxb-...        # Bot User OAuth Token
-TURNSTONE_SLACK_APP_TOKEN=xapp-...    # App-Level Token (Socket Mode)
-TURNSTONE_SLACK_CHANNELS=             # optional, comma-separated channel IDs
-TURNSTONE_SLACK_SLASH_COMMAND=/turnstone
-```
-
-**CLI flags** (bare-metal):

-  --slack-token "xoxb-..." \
-  --slack-app-token "xapp-..." \
-  --slack-slash-command /turnstone \
-  --server-url http://localhost:8080
-```
-
-The Slack and Discord adapters can be enabled together — pass tokens for
-both and the gateway hosts both adapters in one process.
-
-### 3. Usage

-  scoped to that DM; the slash command is not required.
-- **Slash command**: `/turnstone <message>` in any channel the bot can
-  see starts a per-user channel session.
-- Tool approvals render as Slack **Block Kit** buttons; only the user

-- Notifications and reply routing work identically to Discord.
-- Session recovery: persisted channel routes are re-subscribed when the

-
-**Reconnection contract:** a freshly-opened SSE connection receives
-the current snapshot of any pending tool approval (`approve_request`
-is re-sent if unresolved), any in-flight `wait_*` / `batch_*`
-indicator, the worker's current `state_change`, and an
-`in_progress_snapshot` carrying any partial content / reasoning the
-model has produced for the in-progress turn — so a tab refresh
-mid-approval, mid-tool-execution, or mid-stream restores both the
-correct composer mode and the partial assistant text without waiting
-for the response to complete.
-
----
-
-## 3. Send the first user message
-
-```http
-POST /v1/api/workstreams/{ws_id}/send
-Content-Type: application/json
-
-{"message": "audit /auth for CSRF handling across all active routes"}
-```
-
-```http
-HTTP/1.1 200 OK
-{"status": "ok"}
-```
-
-The message is queued for the worker thread at its next tool-result
-seam (so you can send follow-ups mid-conversation without corrupting
-the in-progress turn).  On the SSE stream you'll see `state_change`
-→ `thinking_start` → streaming `reasoning` / `content` / `tool_result`
-events, finishing with `state_change → idle` or an
-`approve_request` when the model invokes a gated tool.
-
----
-
-## 4. Inspect direct children
-
-```http
-GET /v1/api/workstreams/{ws_id}/children HTTP/1.1
-```
-
-```json
-{
-  "items": [
-    {"ws_id": "d4e5f6...", "name": "csrf-audit", "state": "running", "node_id": "gpu-3"},
-    {"ws_id": "e1f2a3...", "name": "xss-audit",  "state": "idle",    "node_id": "gpu-1"}
-  ],
-  "truncated": false
-}
-```
-
-The response key is `items`, not `children` — the endpoint shape
-follows the cluster-wide workstream-list idiom rather than the
-coordinator `list_workstreams` tool's (which uses `children`).
-Rows include every state stored for the parent (`running`, `idle`,
-`closed`, ...); the endpoint does not accept a state query param,
-so clients should inspect each row's `state` field and filter
-locally if they want to hide closed/deleted children.  Nested
-coordinator rows are dropped server-side so only interactive
-descendants appear.
-
----
-
-## 5. Inspect one workstream (storage + live block + tail)
-
-```http
-GET /v1/api/cluster/ws/{ws_id}/detail?message_limit=20 HTTP/1.1
-```
-
-```json
-{
-  "persisted": { "ws_id": "...", "state": "running", "parent_ws_id": "...", "kind": "interactive", ... },
-  "live":      { "state": "thinking", "tokens": 12843, "activity": "...", "pending_approval": null },
-  "tail":      [ {"role": "assistant", "content": "...", "tokens": 128}, ... ]
-}
-```
-
-Works for any workstream the caller has `admin.cluster.inspect` on,
-not just children of a single coordinator — useful for a cluster
-admin panel watching multiple coordinators at once.  `live` is
-`null` when the owning node is unreachable or has dropped the row
-from its dashboard cache; callers should degrade gracefully, not
-treat it as an error.
-
-For fan-out views, prefer
-[`GET /v1/api/cluster/ws/live?ids=a,b,c`](bulk-endpoints.md) — it
-collapses N per-row round-trips into one, returning the live block
-for every id in a `{results, denied, truncated}` envelope.
-
----
-
-## 6. Wait for fan-out (`wait_for_workstream`)
-
-`wait_for_workstream` is a **model-side tool**, not an HTTP endpoint
-— the coordinator's LLM invokes it with a list of child ws_ids, the
-session's worker thread blocks inside the tool, and a sequence of
-`wait_started` / `wait_progress` / `wait_ended` SSE events is emitted
-for the UI to drive a "waiting on N children" indicator.
-
-![wait_for_workstream sequence](diagrams/png/27-coordinator-wait-for-workstream.png)
-
-Key properties:
-
-- **Caps** — up to 32 ws_ids per call, up to 600 seconds per call.
-  A coordinator that needs to wait on more children re-invokes the
-  tool with a fresh timeout.
-- **Modes** — `mode="any"` returns as soon as one child reaches a
-  real terminal state (`idle` / `error` / `closed` / `deleted`);
-  `mode="all"` waits for every polled child to reach a real
-  terminal state.
-- **Progress throttling** — the poll loop runs every 500 ms but the
-  SSE emission is diff-on-state-change plus a 5-second heartbeat.  A
-  600 s wait generates O(dozens) of progress events, not 1200.
-- **Unresolvable ids** — ws_ids are validated up front (exactly
-  32 hex chars; copy them verbatim): a malformed id fails the call
-  immediately with did-you-mean suggestions and a roster of the
-  coord's children.  An id the caller doesn't own, a missing row, or
-  a child hard-deleted mid-wait is reported as `state="not_found"`
-  and aborts the wait on the tick that observes it (top-level
-  `error` / `not_found` / `children` fields, `complete=false`) — the
-  LLM should fix the id and re-issue, not conclude the child died.
-  Foreign and missing collapse into one shape, so the wait can't be
-  used as an existence oracle.
-
-Prefer `wait_for_workstream` over polling `inspect_workstream` in a
-loop — a wait consumes one assistant turn regardless of how long the
-children take, whereas each `inspect_workstream` poll costs a full
-turn (plus judge, plus tokens).  On a fan-out of 3+ children this
-rounds to a 10× token-efficiency win.
-
----
-
-## 7. Governance — trust, restrict, close_all_children
-
-These three endpoints let an operator steer a live coordinator session
-mid-flight.  All three emit an audit event tagged
-`coordinator.<action>` via the dedicated audit executor so a cascade
-burst can't starve audit writes.
-
-### `POST /trust` — auto-approve own-subtree sends
-
-```http
-POST /v1/api/workstreams/{ws_id}/trust
-{"send": true}
-```
-
-Flips `trust_send=true` on the live session.  Subsequent
-`send_to_workstream` calls that target a ws_id in the coordinator's
-own subtree skip the approval prompt; foreign ws_ids and other tool
-calls still go through the normal flow.  Requires both
-`admin.coordinator` AND `coordinator.trust.send` permissions (the
-second grants a service token the opt-in it otherwise wouldn't get).
-
-### `POST /restrict` — revoke tool access mid-session
-
-```http
-POST /v1/api/workstreams/{ws_id}/restrict
-{"revoke": ["spawn_workstream", "delete_workstream"]}
-```
-
-Unions the names into the session's revoked-tools set.  Additive and
-idempotent — calling twice with overlapping lists converges to the
-union.  Revocations don't survive a session close/reopen; operators
-opt in per session.  Cap 256 tool names per request, 128 chars each.
-
-### `POST /close_all_children` — soft-close the direct fan-out
-
-```http
-POST /v1/api/workstreams/{ws_id}/close_all_children
-{"reason": "audit round complete"}
-```
-
-Response:
-
-```json
-{"status": "ok", "closed": ["c-1", "c-2"], "failed": [], "skipped": []}
-```
-
-Soft-close cascade bounded by a concurrency semaphore.  The `reason`
-(up to 512 chars) propagates into each closed child's audit +
-`workstream_config` for postmortem.  The model-facing tool that
-pairs with this endpoint asks for a bounded teardown of the
-coordinator's own fan-out.  This *soft-closes*; to *cancel* the
-fan-out instead, cancel the coordinator (§8) — a coordinator cancel
-auto-cascades to its direct children.
-
-See [bulk-endpoints.md](bulk-endpoints.md) for why `close_all_children`
-uses the cascade-mutation shape and how it differs from the
-`spawn_batch` / `cluster/ws/live` shape.
-
----
-
-## 8. Approve / cancel
-
-The `approve` endpoint is what resolves an `approve_request` SSE
-event.  The coordinator's worker thread is blocked inside
-`ui.approve_tools` waiting for this POST.
-
-```http
-POST /v1/api/workstreams/{ws_id}/approve
-{"approved": true, "feedback": null, "always": false}
-{"approved": false, "feedback": "spawn count looks too high — try 3 not 10"}
-{"approved": true, "feedback": null, "always": true}    // always-approve this tool name
-```
-
-`cancel` drops the coordinator's in-flight generation and, for a
-coordinator, auto-cascades the cancel to its direct children:
-`cancel_workstream` is dispatched through the routing proxy for
-every direct child in the registry.  The coordinator itself is left
-idle and open for a fresh `send`:
-
-```http
-POST /v1/api/workstreams/{ws_id}/cancel
-{}
-```
-
----
-
-## 9. Close
-
-```http
-POST /v1/api/workstreams/{ws_id}/close
-{}
-```
-
-Soft-closes the session — state persists, children keep running
-(wind them down first with `close_all_children`, or by cancelling
-the coordinator, which cascades the cancel to its direct children),
-the worker thread exits, SSE streams send a final `stream_end` and
-disconnect.  The row is reopenable via
-`POST /v1/api/workstreams/{ws_id}/open` so long as it hasn't been
-deleted.

-# Writing a coordinator-specific skill
-
-A skill is prompt-level framing that steers a Turnstone session
-toward a narrow task.  Most skills target **interactive** sessions —
-the single-workstream "do this thing" surface where the model wields
-`bash`, `edit_file`, `web_fetch`, and the rest of the maker toolset.
-
-A **coordinator skill** is different.  It runs on a session whose job
-is to orchestrate other sessions.  The toolset is smaller and
-narrower, the role is an orchestrator instead of a maker, and the
-success metric is "did the plan resolve" instead of "did the code
-compile".  This doc covers the differences a skill author has to
-care about.
-
----
-
-## `kind` — authored audience metadata
-
-A row in `prompt_templates` carries a `kind` column (see
-[`turnstone/core/skill_kind.py`](../turnstone/core/skill_kind.py);
-migration 044 added the column).  Three values:
-
-| `SkillKind` enum        | Stored as       | Meaning                                                                    |
-|-------------------------|-----------------|----------------------------------------------------------------------------|
-| `SkillKind.INTERACTIVE` | `"interactive"` | Authored for the interactive maker role (single-workstream "do this"). |
-| `SkillKind.COORDINATOR` | `"coordinator"` | Authored for the orchestrator role (delegate, monitor, synthesise).    |
-| `SkillKind.ANY`         | `"any"`         | Either surface (or audience-neutral).  Default on create.                 |
-
-The `kind` field is a `StrEnum` — drop-in `str` compatible — so DB
-rows, JSON payloads, and `==` comparisons all work without translation
-at the edge.
-
-**`kind` is metadata, not an enforcement boundary.**  The model can
-`skills(action='find')` across every kind from any session, `get` any
-row by name, and `load` any visible skill regardless of session kind.
-Actual runtime capability is gated by `allowed_tools` + `auto_approve`
-on the skill and the operator's approval card on every `load` /
-`spawn_workstream(skill=...)` decision — `kind` doesn't add or remove
-any of that.  It's a sorting / grouping / search-narrowing hint.
-
-The opt-in filter is on `skills(action='find', kind='coordinator')`
-(or `'interactive'`) — pass it when you want to narrow a catalog
-browse to a specific authored audience.  Omitting it (or passing
-`kind='any'`) returns the full catalog.  When supplied, the storage
-filter widens to `[<kind>, 'any']` so audience-neutral rows remain
-visible inside the narrowed view.
-
-**Tagging a new skill as coordinator-targeted** — set `kind` to
-`SkillKind.COORDINATOR` (or the literal `"coordinator"`) when you
-`skills(action='create', kind='coordinator', ...)` or POST to
-`/v1/api/admin/skills`.  Use this to signal intent to other skill
-authors and to make the orchestrator-targeted catalog easy to
-browse — not to hide the skill from interactive sessions.  Existing
-rows default to `SkillKind.ANY`; bump them to `COORDINATOR` if
-you've rewritten the prompt around the orchestrator toolset and
-want the kind filter to surface them as such.
-
----
-
-## Tool surface differences
-
-Coordinator sessions receive a **fixed** tool set, defined in
-`turnstone/core/tools.py` as `COORDINATOR_TOOLS`.  Nothing a skill
-or MCP config can do adds to it.  Current members:
-
-| Tool                      | Category        | Notes                                                               |
-|---------------------------|-----------------|---------------------------------------------------------------------|
-| `spawn_workstream`        | delegate        | Create one child.  Requires approval.                               |
-| `spawn_batch`              | delegate        | Create up to 10 children in one approval.  Partial-success shape.   |
-| `inspect_workstream`      | observe         | Read state + tail of one child.  Auto-approved (no mutation).       |
-| `list_workstreams`        | observe         | List the direct children (same shape as `/children` endpoint).      |
-| `wait_for_workstream`     | block           | Block until one/all listed children hit a terminal state.           |
-| `send_to_workstream`      | steer           | Queue a follow-up message to a running child.                        |
-| `close_workstream`        | wind-down       | Soft-close one child.  Requires approval.                           |
-| `close_all_children`      | wind-down       | Soft-close every direct child in one approval.  Partial-success shape. |
-| `cancel_workstream`       | wind-down       | Drop the in-flight generation; leaves child idle for a fresh send.  |
-| `delete_workstream`       | wind-down       | Hard-delete one child.  Requires approval.                          |
-| `list_nodes`              | discover        | Enumerate live cluster nodes + capabilities.                        |
-| `skills` (action=find)    | discover        | Browse the skill catalog; opt-in `kind` filter narrows by audience. |
-| `memory`                  | persist         | Durable orchestration memory (`coordinator` scope, per-user — survives across coordinator sessions). |
-| `notify`                  | broadcast       | Post a status update to a human channel at a narrative beat.        |
-| `tasks`                   | plan            | Orchestrator-only scratchpad.  Children don't see it.               |
-
-Explicitly **not** in the coordinator set:
-
-- `bash` / `edit_file` / `write_file` / `append_file` / `diff_file` — no local FS.
-- `read_file` / `search` — no local FS reads.
-- `web_fetch` / `web_search` — no direct web access.
-- `task_agent` — sub-agent tool is zeroed on coord sessions.
-- `recall` / `watch` / `read_resource` / `use_prompt` — UX / persistence tools that belong to interactive sessions.  The dual-kind `memory` / `skills` / `notify` tools are available on both kinds (see the table above).
-
-If your skill needs a coordinator to "run a command" or "read a
-file", write the delegate pattern instead: spawn a child with an
-appropriate skill, `wait_for_workstream`, then `inspect_workstream`
-for the output.  The coordinator stays the orchestrator.
-
----
-
-## Framing differences
-
-Interactive skills compose on top of `base_interactive.md` — a
-"maker" framing: get the work done, use the tools, edit the code,
-close the loop.
-
-Coordinator skills compose on top of
-[`personas/orchestrator.md`](../turnstone/prompts/personas/orchestrator.md) —
-an "orchestrator" framing: decompose, delegate, monitor, synthesise.
-The base text is short but sets the tone every coordinator skill
-inherits:
-
-> You are a coordinator.  Your role is to orchestrate work across
-> the cluster...  You do
-> not edit files, run shell commands, browse the web, or manipulate
-> the codebase directly.  Children do that.
-
-Write your skill's system prompt to *add* task-specific orchestration
-hints on top — don't re-explain the role, don't paste tool JSON,
-don't try to override the "no direct action" contract.  Keep the
-additions to: (a) the specific kind of work this skill delegates;
-(b) the preferred skill tags for children; (c) the synthesis shape
-the skill should end on.
-
----
-
-## `tasks` integration
-
-`tasks` is the coordinator's scratchpad — a persisted, ordered
-list of rows with fields `{id, title, status, child_ws_id, created,
-updated}` that only this coordinator sees.  Children don't see it;
-the user does via the sidebar.  Five actions: `add`, `update`,
-`remove`, `reorder`, `list` (only `list` is auto-approved; the
-mutators go through the approval flow).
-
-The input schema refers to rows by `task_id`; the persisted row
-object exposes the same id as `id`.  The `child_ws_id` field is a
-free-form label the skill sets to link a task to a spawned
-workstream — it is NOT validated against the workstreams table, so
-a skill can set it to a placeholder before `spawn_workstream`
-returns or keep it pointing at a closed child for later audit.
-
-A skill's initial prompt can seed the task list by calling
-`tasks(action="add", title=...)` as its very first tool calls —
-the user gets a visible plan before any child is spawned, and the
-coordinator's future self has something concrete to iterate on.
-Status transitions (`pending` → `in_progress` → `done` / `blocked`)
-are the skill's main feedback loop: mutate the task when the child
-covering it finishes, not when the child starts.  Use
-`tasks(action="update", task_id=..., child_ws_id=<ws_id>)` to
-link a task to the child that owns it once spawn returns.
-
-A final gotcha: parallel tool dispatch does NOT serialise reads
-after writes in the same batch.  If a skill issues an `update` and
-a `list` in one parallel tool batch, the `list` response may reflect
-the pre-update state.  Dispatch mutate and list serially (one
-tool_use turn each) when the list must observe the mutation.
-
-Keep the tasks coarse-grained — one per child, roughly.  A 20-task
-list for a 3-child fan-out is noise; a 1-task list for a 5-child
-fan-out loses the plan.  The sidebar renders tasks as the operator's
-mental model of "what the coord thinks it's doing".
-
----
-
-## Referencing children by `ws_id`
-
-Every ws_id returned by `spawn_workstream` / `spawn_batch` is a
-**full 32-char hex string**.  The skill's system prompt must not
-invent ws_ids — a model that hallucinates `"child-1"` or `"ws-abc"`
-hits the tenant guard in `CoordinatorClient._is_own_subtree`, which
-validates ws_id against `parent_ws_id=coord_ws_id` AND
-`user_id=owner` in storage.  The rejection shape is uniform and
-recovery-oriented:
-
-- **Mutating ops** (`send_to_workstream`, `close_workstream`,
-  `cancel_workstream`, `delete_workstream`) and
-  **`inspect_workstream`** return
-  `{"error": "no workstream matching '<ref>' among your children; …",
-  "status": 404, "ws_id": "<ref>", "did_you_mean": [...],
-  "children": [...], "children_truncated": bool}` — a did-you-mean
-  (edit distance ≤ 3 against the coord's own children, which catches
-  the garbled-hex incident class: a 32-char id whose `aaa` run
-  collapsed to `a`) plus a roster of the coord's children.  A ref
-  that matches a child's display NAME is called out explicitly with
-  the right id (names are mutable labels, not addresses).  Foreign
-  and nonexistent ids produce the same payload (no existence
-  oracle), every hint references only the coord's own children, and
-  near-miss ids are never auto-resolved — the skill should fix the
-  id and re-issue, not treat the child as dead.
-- **`wait_for_workstream`** validates ids before waiting: a
-  malformed id fails the whole call immediately (`invalid_ws_ids`
-  carries the per-id payloads above, `elapsed=0`); a well-formed id
-  that is foreign, nonexistent, or hard-deleted mid-wait surfaces as
-  `state="not_found"` and aborts the wait on that tick with
-  top-level `error` / `not_found` / `children` fields.
-  `complete=true` therefore means every polled lane really finished
-  — an unobservable id can neither burn the timeout nor ride along
-  to a "complete" result.
-
-Pattern: capture each spawn result in the next tool call's input.
-The JSON tool-result carries `{"child_ws_id": "...", "name": "...",
-"node_id": "...", "routing_strategy": "..."}`; the model should
-extract the `child_ws_id` and pass it as `ws_id` (or in the `ws_ids`
-list) to `inspect_workstream` / `wait_for_workstream` /
-`send_to_workstream` / `close_workstream` verbatim.  The asymmetry
-— spawn returns `child_ws_id` but the other tools accept `ws_id` /
-`ws_ids` — is intentional: it defuses a coordinator-LLM recency
-bias where seeing `ws_id` in a spawn return primed re-spawn loops
-instead of progression to the wait phase.
-
-A UI that wants human-readable identifiers should render the `name`
-field and keep the workstream id as the click-through key — note
-that the id *value* is the same regardless of whether it arrived
-under the `child_ws_id` key (spawn return) or the `ws_id` key
-(every other tool's input/output); only the field name differs.
-
----
-
-## `wait_for_workstream` vs `inspect_workstream`
-
-Two distinct semantics, different cost profiles:
-
-- **`wait_for_workstream(ws_ids=[...], timeout=60, mode="any")`** —
-  blocks inside a single tool call until one (or all, for `mode="all"`)
-  of the listed children reaches a terminal state (`idle`, `error`,
-  `closed`, `deleted`).  The worker thread blocks up to `timeout`
-  seconds; the assistant turn remains a single round-trip regardless
-  of how long the wait actually takes.  Prefer this for "the plan
-  needs child X to finish before the next step."
-- **`inspect_workstream(ws_id=...)`** — single read of the child's
-  state + tail.  Costs a full assistant turn (judge, tokens, stream).
-  Prefer this for "what does the final message say?" after the child
-  has already resolved (via `wait_for_workstream` or a known
-  transition).
-
-Rule of thumb: wait once for a fan-out, then inspect once per
-child for the content.  A loop of inspect-every-few-seconds is a
-token-burning antipattern — on 3+ children it rounds to a 10×
-efficiency hit over a wait+inspect pair.
-
----
-
-## Common coordinator patterns
-
-Three patterns cover most coordinator skills.  Pick the one that
-matches the task, or combine them deliberately.
-
-### Pattern 1 — delegate-and-summarise
-
-One specialist child, one focused brief, one synthesis message back
-to the user.  Appropriate when the user's request is "run the thing
-and tell me what happened" and the work fits in one workstream.
-
-```
-tasks(action='add', title='audit /auth for CSRF')
-spawn_workstream(skill='engineer', initial_message='audit /auth ...')
-wait_for_workstream(ws_ids=[<child>], timeout=300)
-inspect_workstream(ws_id=<child>)
-→ synthesise the final message into a user-facing response
-tasks(action='update', task_id='t_01', status='done')
-close_workstream(ws_id=<child>, reason='audit complete')
-```
-
-### Pattern 2 — fan-out-and-synthesise
-
-N children running in parallel, each with a distinct brief, all
-waited-on together, then synthesised.  Appropriate when the user's
-request naturally decomposes into independent subtasks.
-
-```
-tasks seeds:
-  t_01 benchmark Anthropic 4.7 latency on summarisation
-  t_02 benchmark OpenAI GPT-5.2 latency on summarisation
-  t_03 benchmark Gemini 2.5 latency on summarisation
-spawn_batch(children=[...3 briefs...])
-wait_for_workstream(ws_ids=[c1, c2, c3], mode='all', timeout=600)
-inspect_workstream(ws_id=c1); ...(c2); ...(c3)
-→ synthesise head-to-head comparison
-tasks → all done
-close_all_children(reason='benchmark complete')
-```
-
-Prefer `spawn_batch` over 3 individual `spawn_workstream` calls —
-one approval instead of three, one audit trail, deterministic
-sibling ordering.  Pair with `wait_for_workstream(mode='all')` and
-`close_all_children(reason=...)` to wind the fan-out down in one
-approval each.
-
-### Pattern 3 — plan-then-delegate
-
-The coordinator first uses its own reasoning to carve the plan,
-records it in `tasks`, then spawns children that each own one
-task.  Appropriate when the user's request is "figure out how to X"
-and the coordinator's planning step is itself valuable.
-
-```
-→ coord reasons about the shape of the work
-tasks(action='add', title='...') × N   # the plan, visible in the sidebar
-for task in tasks:
-    spawn_workstream(skill=..., initial_message=task.brief)
-    tasks(action='update', task_id=task.id, notes='ws=<child_ws_id>')
-wait_for_workstream(ws_ids=[...], mode='all', timeout=...)
-for child in children:
-    inspect_workstream(ws_id=child)
-    tasks(action='update', task_id=..., status='done', notes='result summary')
-→ synthesise
-```
-
-The key distinction from Pattern 2: the plan is an artifact the user
-can see and interact with (via the sidebar).  If the coordinator's
-reasoning-pass was wrong about the decomposition, the user can
-course-correct before any child runs.
-
----
-
-## Testing a coordinator skill
-
-Coordinator sessions are hosted on the console, not on a node.
-Integration tests that drive a real coord session live under
-`tests/test_coordinator_end_to_end.py` — they spin a console with
-an in-memory SQLite backend and a fake upstream node, then drive
-the session through its HTTP surface.
-
-For a new coordinator skill:
-
-1. Write the skill prompt as a string and pass it to the
-   `coord_session` fixture's `skill=` kwarg (see
-   `tests/test_coordinator_tools.py` for the pattern).
-2. Build a small fake cluster: one node + two children via
-   the `_seed_children` helper in `tests/_coord_test_helpers.py`
-   (``_seed_children(mgr._adapter, coord.id, ["child-1", "child-2"])``).
-3. Drive the session with seeded tool_call dicts matching the
-   provider layer's shape.  The unit-level tests in
-   `tests/test_coordinator_tools.py` show the helper (`_tc(name,
-   args, call_id)`).
-4. Assert the skill's decision shape — which tools fire in what
-   order, what the tasks looks like at the end, which
-   `_error` reasons appear on the denied-path.
-
-A full end-to-end test isn't required for every skill; a
-prepare-step unit test that asserts "given this initial message, the
-first tool call is X with Y args" is usually sufficient to catch
-framing drift without a real LLM in the loop.

 # Consistent Hash Ring — Reference Design
 
-**Status**: Reference — alternative routing strategy
+**Status**: Reference (not currently in the hot path)
+**Date**: 2026-03-30
 
-Live routing uses **rendezvous (HRW) hashing** in
-`turnstone/core/rendezvous.py` and `turnstone/console/router.py`.  This
-document captures a vnode-ring approach as a reference for future
-evaluation if the cluster outgrows rendezvous's O(N)-per-route
-characteristic.
+## Overview
 
-The FNV-1a-32 hash function specified below is bit-identical to the
-hash used by the live rendezvous implementation; cross-language clients
-can rely on these test vectors.
+This document describes a consistent hash ring algorithm evaluated during
+the design of the direct HTTP transport routing system. The current
+implementation uses weight-proportional bucket assignment with a
+donor/recipient rebalancing algorithm (see `direct-http-transport.md`).
+The consistent hash ring is documented here as a reference for future
+scalability work — if the cluster grows beyond the point where the
+weight-proportional approach is sufficient, the ring provides a
+proven alternative with stronger stability guarantees.
 
-## When the ring approach becomes interesting
+## When to consider the ring approach
 
-The vnode ring becomes preferable to rendezvous hashing when:
+The current weight-proportional seeding + donor/recipient rebalancer works
+well when:
+- Cluster size is moderate (< 50 nodes)
+- Nodes join/leave infrequently
+- The rebalancer runs centrally (in the console)
 
-- Cluster size grows large (50+ nodes) and the per-route O(N) hash
-  computation becomes visible against downstream HTTP cost.
-- Decentralised routing is needed (each node computes the ring locally,
-  no central console required).
-- A precomputed flat-array lookup is desired so the routing hot path
-  avoids hashing entirely.
+The consistent hash ring becomes advantageous when:
+- Cluster size grows large (50+ nodes) and frequent membership changes
+  cause the donor/recipient algorithm to churn
+- Decentralized routing is needed (each node computes the ring locally,
+  no central console required)
+- Cross-language determinism is important (multiple implementations must
+  agree on the same assignment without sharing state)

 # Docker Deployment
 
-Turnstone ships two Docker Compose stacks:
+Docker Compose stack for running the full turnstone platform.
 
-| Stack | File | Use it for |
-|-------|------|------------|
-| **Dev cluster** | `compose.yaml` (repo root) | Clone-and-run. Builds locally, zero config, full 10-node cluster. |
-| **Production** | `turnstone/deploy/compose.yaml` | Pip/pipx installs. Pulls released images from ghcr.io, requires real secrets. |
-
-## Quick start — local cluster
+## Quick Start
 
 ```bash
-git clone https://github.com/turnstonelabs/turnstone
-cd turnstone
+# Copy and edit environment config
+cp .env.example .env
+
+# Full stack (needs an LLM API on the host)
 docker compose up
 ```
 
-That builds one image and brings up the whole stack: PostgreSQL, the console,
-Caddy, the channel gateway, and **10 server nodes** (`node-1`…`node-10`). No
-`.env` is required — it ships with insecure dev defaults so it just works.
+Console dashboard: http://localhost:8090
 
-Open the dashboard at **https://localhost:8443**. It's served by Caddy with its
-own local CA, so trust the root certificate once (or click through the browser
-warning):
+> See also: [Deployment diagram](diagrams/png/12-deployment.png)
+
+## Services
+
+| Service | Port | Profile | Description |
+|---------|------|---------|-------------|
+| `server` | 8080 | default | Web UI + chat workstreams + LLM |
+| `console` | 8090 | default | Cluster dashboard |
+| `channel` | — | production | Channel gateway (Discord, Slack, etc.) |
+| `server-1`…`server-10` | — | cluster | 10-node server fleet (PostgreSQL required) |
+
+## Profiles
+
+**Default** (no flag) — starts `server` and `console`. Requires an OpenAI-compatible LLM API running on the host (default: `http://localhost:8000/v1`).
 
 ```bash
-docker compose exec caddy cat /data/caddy/pki/authorities/local/root.crt
+docker compose up
 ```
 
-Create your first admin user (any node works — they share one database):
+**Production** — adds PostgreSQL and the channel gateway. Requires `POSTGRES_PASSWORD` and (for Discord) `TURNSTONE_DISCORD_TOKEN`:
 
 ```bash
-docker compose exec node-1 turnstone-admin create-user --username admin --name "Admin"
+docker compose --profile production up
 ```
 
-### Bring your own LLM
-
-Nodes boot **without** an LLM and appear in the console immediately. Add real
-model backends (OpenAI, Anthropic, or a local/vLLM endpoint) from the console
-UI's **Models** tab. To set a node's bootstrap default instead, point
-`LLM_BASE_URL` / `OPENAI_API_KEY` at an OpenAI-compatible endpoint in `.env`.
-
-### Fewer nodes
-
-Ten nodes is heavy on a laptop. Start a subset by naming the services (always
-include `postgres`, `console`, and `caddy`):
+**Cluster** — 10-node server fleet sharing PostgreSQL. Access all nodes via the console at `:8090`. Requires `POSTGRES_PASSWORD`:
 
 ```bash
-docker compose up postgres console caddy channel node-1 node-2 node-3
+docker compose --profile cluster up
 ```
 
-## Why HTTPS-only?
-
-The console's plain-HTTP port (8090) is **not** published to the host. A plain
-HTTP/1.1 origin caps the browser at 6 connections, which starves the
-dashboard's per-pane SSE streams. Caddy serves the browser over HTTP/2
-(multiplexed) and proxies to `console:8090` on the internal network, so the cap
-is gone. Everything goes through `https://localhost:8443`.
-
-## Join a bare-metal host
-
-PostgreSQL, the console's ACME endpoint (`:8090`), and SearxNG (`:8081`) are
-published on `127.0.0.1`, so a `turnstone-server` running directly on the same
-machine — for example to use a local GPU — can join the same cluster (enrolling
-its mTLS cert and running `web_search`) and show up in the console alongside the
-containerized nodes.
-
-Put the secret and connection settings in `~/.config/turnstone/config.toml`
-(secrets belong in this file, not the process environment — keep it `0600`,
-the loader warns otherwise):
-
-```toml
-[auth]
-jwt_secret = "dev-only-insecure-jwt-secret-change-me-for-real-deployments"
-
-[database]
-backend = "postgresql"
-url = "postgresql+psycopg://turnstone:turnstone@localhost:5432/turnstone"
-
-[api]
-base_url = "http://localhost:8000/v1"   # your local model endpoint
-api_key = "dummy"
-```
-
-Then start the server. The node identity isn't a secret, so it stays on the
-command line:
-
-```bash
-chmod 600 ~/.config/turnstone/config.toml
-TURNSTONE_NODE_ID=host-1 \
-  TURNSTONE_ADVERTISE_URL=http://host.docker.internal:8080 \
-  TURNSTONE_CONSOLE_URL=http://localhost:8090 \
-  TURNSTONE_SEARXNG_URL=http://localhost:8081 \
-  turnstone-server --host 0.0.0.0 --port 8080
-```
-
-The host server registers itself in PostgreSQL; the console reaches it back via
-`host.docker.internal`. `TURNSTONE_CONSOLE_URL` points the node at the console's
-published ACME endpoint so it can enroll its mTLS certificate (needed only when
-the cluster runs mTLS; harmless otherwise), and `TURNSTONE_SEARXNG_URL` points
-`web_search` at the published SearxNG. The `jwt_secret` and DB credentials above
-are the dev-stack defaults — match whatever you set in `.env` if you changed them.
-
-To let a server on a **different** machine join, start the stack with
-`TURNSTONE_HOST_IP=<this host's LAN IP>` — that binds PostgreSQL, the console
-ACME endpoint, and SearxNG to that interface. Then on the remote box set the
-three URLs above to that IP, and set `TURNSTONE_ADVERTISE_URL` to the **remote**
-box's own IP (the address the console dials back). **Set a strong
-`POSTGRES_PASSWORD` first** — `TURNSTONE_HOST_IP` exposes the database (and every
-user account + API-token hash in it), the console API, and the unauthenticated
-SearxNG to your network.
-
-To run the bare-metal node as a hardened, persistent service instead of by hand,
-use the systemd units in [`deploy/systemd/`](../deploy/systemd/).
-
-## Production stack
-
-For a real deployment use the bundled stack, which pulls released images
-instead of building:
-
-```bash
-docker compose -f turnstone/deploy/compose.yaml up
-```
-

-PostgreSQL all share one database so the console discovers the node — but it
-pulls released images, runs a single server node, and has **no baked-in

-
-```bash
-TURNSTONE_JWT_SECRET=<python -c "import secrets; print(secrets.token_hex(32))">

-```
-
-The dashboard is at **https://localhost:8443** (Caddy, same as the dev stack);
-the console's HTTP port isn't published. For a real domain and a publicly
-trusted cert, edit `turnstone/deploy/Caddyfile` to point Caddy at Let's Encrypt
-(see [tls.md](tls.md)). Pin the image with `TURNSTONE_IMAGE_TAG` (default:
-`latest`).
-
-### mTLS
-
-Layer the TLS overlay on the production stack to enable mutual TLS between
-services. A bootstrap container creates a CA and every service auto-provisions
-certs via the console's ACME endpoint:
-
-```bash
-docker compose -f turnstone/deploy/compose.yaml -f deploy/docker-compose.tls.yml up
-```
-
-See [tls.md](tls.md) for details.
-
 ## Configuration
 
-Everything is configured with environment variables in `.env` (copy from
-[`.env.example`](../.env.example)). The dev stack needs none of them — they're
-overrides.

-|----------|----------------------|-------------|
-| `TURNSTONE_JWT_SECRET` | insecure default / **required** | JWT signing secret. Every service must share one value. |
-| `TURNSTONE_DB_BACKEND` | `postgresql` | `sqlite` or `postgresql`. Multi-node discovery requires `postgresql`. |
-| `TURNSTONE_DB_URL` | bundled Postgres | SQLAlchemy URL. Override to use an external database. |
-| `POSTGRES_USER` | `turnstone` | PostgreSQL username |

-### Ports
-

+### Server
 
 | Variable | Default | Description |
 |----------|---------|-------------|
-| `CONSOLE_HTTPS_PORT` | `8443` | Host port for Caddy (dashboard HTTPS) |
-| `SEARXNG_HTTPS_PORT` | `8444` | Host port for the SearxNG UI via Caddy (dev: localhost-only; prod: opt-in) |
-| `POSTGRES_PORT` | `5432` | Host port for PostgreSQL (for bare-metal joins) |
-| `SEARXNG_API_PORT` | `8081` | Host port for the SearxNG API a bare-metal node's `web_search` dials (dev stack) |
-| `TURNSTONE_HOST_IP` | `127.0.0.1` | Interface PostgreSQL, the console ACME endpoint, and SearxNG bind on (dev stack). Set to this host's LAN IP so a bare-metal node on **another machine** can reach them — set a strong `POSTGRES_PASSWORD` first (it also exposes the DB and the unauthenticated SearxNG to your network). |
-| `POSTGRES_BIND` | `127.0.0.1` | Production stack (`turnstone/deploy/compose.yaml`) only: interface PostgreSQL binds on; set to the host's LAN IP for remote joins. |
+| `SERVER_PORT` | `8080` | Host port mapping |
+| `SKIP_PERMISSIONS` | — | Set to any value to auto-approve all tools |
 
-### Channel gateway
+### Console
 
 | Variable | Default | Description |
 |----------|---------|-------------|
-| `TURNSTONE_DISCORD_TOKEN` | — | Discord bot token (enables the Discord adapter) |
-| `TURNSTONE_DISCORD_GUILD` | `0` | Restrict to one guild (0 = all) |
-| `TURNSTONE_SLACK_TOKEN` | — | Slack Bot User OAuth token `xoxb-…` |
-| `TURNSTONE_SLACK_APP_TOKEN` | — | Slack App-Level token `xapp-…` (with the Slack token) |
+| `CONSOLE_PORT` | `8090` | Host port mapping |
 
-The channel runs HTTP-only with no adapters until a token is set, so it's safe
-to leave running. See [Channel Integrations](channels.md) for app setup.
+### Auth
 
-### Web search (SearxNG)
-
-The `web_search` tool for local/vLLM models is backed by a self-hosted
-[SearxNG](https://searxng.org) metasearch service, bundled into both stacks as the
-`searxng` service. The Turnstone nodes reach it over the internal docker network at
-`http://searxng:8080` — its API port is **not** published. Its config —
-[`turnstone/deploy/searxng/settings.yml`](../turnstone/deploy/searxng/settings.yml),
-mounted read-only — enables the JSON API and leaves the rate limiter off (the
-limiter would need a separate Valkey/Redis instance). A `searxng-cache` volume
-persists its favicon + internal cache across restarts. Commercial providers
-(Anthropic, OpenAI) use their own native search and never touch this service.
-
-Point at an existing SearxNG instead of the bundled one with `TURNSTONE_SEARXNG_URL`,
-or narrow the engines via `tools.searxng_engines` in the admin Settings tab (e.g.
-`duckduckgo,wikipedia`).
-
-**SearxNG web UI.** Caddy can also serve SearxNG's own search/Preferences UI on a
-dedicated port. The dev stack publishes it at **`https://localhost:8444`** bound to
-localhost only; the production stack does **not** publish it by default (uncomment
-the `8444` port on the `caddy` service to opt in). Change the port with
-`SEARXNG_HTTPS_PORT`. **SearxNG has no authentication** — never bind this to a public
-interface, or anyone who can reach it can search through your instance.
-
-> **AGPL note for operators.** SearxNG is licensed AGPL-3.0. Kept on the internal
-> network (or bound to localhost), no external user interacts with it — so the AGPL
-> §13 (remote network interaction) source-offer obligation does not attach. If you
-> publish SearxNG to remote users (bind its port to a public interface, or front it
-> with your own reverse proxy) you become the operator of a network-reachable AGPL
-> service and must offer its corresponding source; that is trivially satisfied by
-> linking to upstream <https://github.com/searxng/searxng>. Turnstone's own license is
-> unaffected: it talks to SearxNG over HTTP as a separate process (mere aggregation),
-> not by linking.

-### Other
+Auth is always enabled. `TURNSTONE_JWT_SECRET` is required.
 
 | Variable | Default | Description |
 |----------|---------|-------------|
-| `WORKSPACE_MOUNT` | empty volume | Host directory bind-mounted at `/workspace` for the model to read/write |
-| `SKIP_PERMISSIONS` | — | Set to any value to auto-approve all tool calls (dev only) |

-## Building
+### Database
 
-Both stacks install all entry points into a single image (`turnstone`,
-`turnstone-server`, `turnstone-console`, `turnstone-channel`, `turnstone-admin`,
-`turnstone-eval`, `turnstone-optimizer`, `turnstone-doctor`):
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `TURNSTONE_DB_BACKEND` | `sqlite` | Storage backend: `sqlite` or `postgresql` |
+| `TURNSTONE_DB_URL` | — | Database URL (e.g. `postgresql://user:pass@db:5432/turnstone`). For SQLite, defaults to `/data/.turnstone.db` |
+| `TURNSTONE_DB_POOL_SIZE` | `2` | PostgreSQL connection pool size per process (default: 2 base + 3 overflow = 5 max) |
+
+The database stores workstream history, user accounts, and API tokens. When using JWT auth, a database backend is required for user storage.
+
+> **Large clusters:** Each turnstone process maintains a small connection pool (5 max). At hundreds of nodes this adds up — use [PgBouncer](pgbouncer.md) in transaction pooling mode between turnstone and PostgreSQL.
+
+> **First-time setup:** After deploying with auth enabled, create an initial admin user by running `turnstone-admin create-user` inside the container:
+>
+> ```bash
+> docker compose exec server turnstone-admin create-user --username admin --name "Admin"
+> ```
+>
+> You will be prompted to set a password. Use it to log in via the UI or SDK, then create additional users through the admin API. Pass `--token --scopes read,write,approve` to also generate an initial API token.
+
+### Channel Gateway
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `TURNSTONE_DISCORD_TOKEN` | — | Discord bot token (required to enable Discord adapter) |
+| `TURNSTONE_DISCORD_GUILD` | `0` | Restrict to a single Discord guild (0 = all guilds) |
+
+The channel service runs in the `production` profile. When `TURNSTONE_DISCORD_TOKEN` is set, the Discord adapter connects to the Discord Gateway and routes messages to the server via HTTP. See [Channel Integrations](channels.md) for full setup instructions including Discord application creation and user account linking.
+
+## Scaling
+
+For multi-node testing, use the `cluster` profile which provides 10 server instances with unique node IDs (`node-1` through `node-10`), resource limits, and shared PostgreSQL:
 
 ```bash
-docker compose build            # build the dev image
-docker compose build --no-cache # rebuild from scratch
+POSTGRES_PASSWORD=secret docker compose --profile cluster up
 ```
 
+The default `server` also runs alongside the cluster nodes (11 total). All nodes are accessible via the console dashboard at `:8090`.
+
+For production clusters beyond ~50 nodes, add PgBouncer between turnstone services and PostgreSQL. See [PgBouncer Connection Pooling](pgbouncer.md) for Docker Compose and Helm configuration.
+
 ## Volumes
 
-| Volume | Purpose |
-|--------|---------|
-| `postgres-data` | PostgreSQL data directory |
-| `turnstone-data` | `/data` per node (SQLite fallback, local state) |
-| `workspace` | `/workspace` (unless `WORKSPACE_MOUNT` is set) |
-| `caddy-data` / `caddy-config` | Caddy's local CA and config (dev stack) |
+| Volume | Mount | Purpose |
+|--------|-------|---------|
+| `turnstone-data` | `/data` | SQLite database (`.turnstone.db`) |
+
+## Building
+
+The image uses a multi-stage Dockerfile:
+
+```bash
+# Build all services
+docker compose build
+
+# Rebuild without cache
+docker compose build --no-cache
+```
+
+All entry points are installed in a single image: `turnstone-server`, `turnstone-console`, `turnstone-channel`, `turnstone-admin`, `turnstone-eval`.

-docker compose down       # stop and remove containers
-docker compose down -v    # also remove volumes (database, certs)
+# Stop and remove containers

-# MCP OAuth — per-user authorization for MCP servers
-
-Turnstone supports **per-(user, MCP server) OAuth 2.1 + PKCE** delegation so each Turnstone user authorizes a remote MCP server with their own identity, rather than sharing a single bearer token across the deployment. This is the right shape for MCP servers that expose user-specific data (a personal CRM, an email inbox, a calendar) and for MCP servers that want per-user audit attribution.
-
-Per-user OAuth is opt-in per `mcp_servers` row. Local-auth Turnstone installs with no `oauth_user` rows exercise zero new code paths — the entire feature is dark by default.
-
-> **Note**: This is a separate authorization layer from Turnstone's own user authentication. A user who logs into Turnstone with a local username + password can still authorize a per-server OAuth MCP server. OIDC SSO and per-server OAuth are orthogonal.
-
----
-
-## When to use which `auth_type`
-
-The MCP server admin form exposes three authorization modes ("Multitenant Authorization"):
-
-| `auth_type` | What it means | When to use |
-|---|---|---|
-| `none` | No headers attached. Open MCP server (or one gated by network policy only). | Internal MCP servers on a trusted network. |
-| `static` | One static bearer token, configured per server, sent on every request from every user. | Service-to-service MCP servers where per-user attribution doesn't matter, or single-tenant deployments. |
-| `oauth_user` *(recommended for user-data servers)* | Each user authorizes separately via OAuth 2.1 + PKCE; Turnstone stores per-user tokens encrypted at rest. | MCP servers that expose user-specific data or that want per-user audit attribution. |
-
-Switching `auth_type` away from `oauth_user` orphans existing per-user tokens. Use the admin **bulk-revoke** affordance on the server row (Phase 9) to clear them, or let them expire naturally — they're inert without the matching `auth_type` value.
-
----
-
-## Prerequisites for `auth_type=oauth_user`
-
-1. **Encryption key**. Tokens are stored encrypted with Fernet. Set `[security] mcp_token_encryption_key` in `config.toml` (Turnstone won't start with an `oauth_user` row configured but no key installed). Rotate via `MultiFernet` — add the new key first, then later remove the old one once all rows have been re-encrypted.
-
-2. **MCP server publishes RFC 9728 PRM and RFC 8414 AS metadata** *or* you configure the AS URL override on the server row. PKCE S256 is mandatory; Turnstone refuses to connect to authorization servers that don't advertise `code_challenge_methods_supported: ["S256"]`.
-
-3. **OAuth client registration**. Two paths:
-   - **Pre-registered** (most common): you create an OAuth client at the authorization server (manually, via admin console, or via Terraform), then paste the `client_id` / `client_secret` into the Turnstone admin form.
-   - **Dynamic client registration** (RFC 7591): if the AS supports it and you select that mode in the admin form, Turnstone registers a client at first use and persists the `client_id` automatically.
-
-4. **Redirect URI** registered at the authorization server: `https://your-turnstone-host/v1/api/mcp/oauth/callback`.
-
----
-
-## Configuration
-
-### Per-server fields (admin UI)
-
-| Field | Required | Description |
-|---|---|---|
-| Server URL | Yes | The MCP server's `streamable-http` base URL. |
-| Multitenant Authorization | Yes | `none` / `static` / `oauth_user` (recommended). |
-| Authorization Server URL | No | Override for RFC 9728 PRM discovery. Set when your AS endpoint differs from the MCP server URL (e.g., corporate AS protecting a third-party MCP). When unset, Turnstone falls back to PRM discovery against the MCP server itself. |
-| Client Registration | Yes (oauth_user) | `preregistered` or `dynamic`. |
-| Client ID | Yes (preregistered) | OAuth 2.0 client ID. Stored unencrypted. |
-| Client Secret | Optional (write-only) | OAuth 2.0 client secret (confidential client). Encrypted at rest. Written but never re-read by the API; field stays masked. |
-| Scopes | No | Space-separated default scope set requested at the authorize endpoint. Per-tool step-up may union additional scopes from a server's `insufficient_scope` response. |
-| Audience | No | RFC 8707 `resource=` parameter sent on every authorize and token request. Defaults to the MCP server URL when unset. Validate against the `aud` claim in returned JWT tokens. |
-
-### Encryption key
-
-```toml
-[security]
-mcp_token_encryption_key = "base64-fernet-key"
-# For rotation, list the keys in priority order — first is used for new
-# writes, all are tried for reads.
-# mcp_token_encryption_keys = ["new-key", "old-key"]
-```
-
-Keep this in `config.toml` rather than environment variables. An in-process LLM with shell-tool access can read the server's environment via `env` / `os.environ` and exfiltrate any secret stored there; secrets in `config.toml` are only loaded into the server at startup and never re-read on a tool-driven path, so a prompt-injection attack against the agent cannot reach them.
-
----
-
-## Lifecycle
-
-1. **First tool call** for a user against an `oauth_user` MCP server: pool dispatch finds no stored token, returns `mcp_consent_required` to the agent. Dashboard renders an inline "Connect" action card.
-
-2. **User clicks Connect**: opens `/v1/api/mcp/oauth/start?server=<name>` in a popup. Browser redirects through the AS authorize endpoint, user grants consent, AS redirects back to `/v1/api/mcp/oauth/callback`. Turnstone exchanges code → tokens via PKCE, validates audience, encrypts, persists in `mcp_user_tokens`, redirects user back to the originating URL.
-
-3. **Subsequent tool calls** by the same user against the same server reuse the persisted token via the per-(user, server) session pool. Tokens auto-refresh via the refresh-token grant when expired; failed refresh emits `mcp_consent_required` to drive re-consent.
-
-4. **Step-up scope**: when a tool call hits `403` with `WWW-Authenticate: error="insufficient_scope"`, Turnstone emits `mcp_insufficient_scope` with the parsed scope set; the dashboard offers a "Connect with additional scopes" affordance that opens `/v1/api/mcp/oauth/start?server=<name>&scopes=<extra>` so the union of original + new scopes flows into the AS authorize request.
-
-5. **User revoke** (settings modal): `DELETE /v1/api/mcp/oauth/connections/{server_name}` runs the authoritative local delete + best-effort RFC 7009 upstream revoke (fire-and-forget, capped at 256 concurrent in-flight tasks).
-
-6. **Admin bulk-revoke** (Phase 9): `POST /v1/api/admin/mcp-servers/{name}/bulk-revoke` drops every user's token for the server. Upstream RFC 7009 revoke is intentionally **not** attempted in bulk (avoids N upstream HTTP calls per admin click); tokens at the AS expire naturally. Use the per-user revoke endpoint if you need guaranteed upstream invalidation.
-
----
-
-## Admin status indicators
-
-The MCP Servers admin tab shows per-server status pills (Phase 9):
-
-- **Consented users count** — distinct users with a non-expired token for this server. Surfaced as a `bulk-revoke (N)` button when ≥1; clicking it opens a confirmation dialog. Hidden when 0.
-- **Last refresh** — timestamp + outcome (`ok` / `error:ClassName`) of the most recent manual or auto-reconnect refresh. Per node. Absent until at least one refresh has occurred (renders as "never" in the admin UI).
-
-Additional indicators (circuit-breaker state, encryption-key mismatch) are exposed via `get_server_status` on the API but do not yet have a dedicated admin pill — operators see them today via the per-server status text + error tooltip and in audit logs. A future phase may surface these as discrete pills.
-
----
-
-## Auth-type transitions
-
-| From | To | What happens |
-|---|---|---|
-| `none` / `static` → `oauth_user` | — | New code path activates for this server. Existing static headers (if any) are no longer sent. Users must authorize on first use. |
-| `oauth_user` → `none` / `static` | — | Existing `mcp_user_tokens` rows are **orphaned** — inert without a matching `auth_type`. Use admin bulk-revoke to drop them, or let them expire. Switching back to `oauth_user` later re-activates the orphaned rows if they haven't been deleted. |
-| OAuth `client_id` or `client_secret` rotated | — | Existing tokens may stop refreshing if the AS treats them as bound to the previous client. Bulk-revoke after rotation. |
-
-The orphan-by-default behavior is chosen so switching back to `oauth_user` is non-destructive. Bulk-revoke is the explicit cleanup path.
-
----
-
-## Troubleshooting
-
-| Symptom | Likely cause | Action |
-|---|---|---|
-| `mcp_consent_required` even after consenting | Token persistence failed, or refresh-token rejected by AS | Check audit log for `mcp_server.oauth.persist_failed` or `mcp_server.oauth.token_revoked`. Re-consent via settings modal. |
-| `mcp_token_undecryptable_key_unknown` | Encryption key rotated without keeping the previous key in the keyring | Add the previous key back to `mcp_token_encryption_keys` until all rows have been re-encrypted, then drop. |
-| `mcp_oauth_url_insecure` | MCP server URL is `http://` (not `https://`) on a non-loopback host | Use `https://`. Per-user bearers must not transit cleartext. |
-| Tools fail in scheduled / Discord / Slack runs | OAuth-MCP requires browser-based consent | Users must pre-consent via the web UI. Phase 9 dashboard badge surfaces deferred consents from these runs on next login. |
-| Circuit breaker open repeatedly | Transport-level errors on the MCP server (DNS, TLS, 5xx) | Check the per-server error pill; auth errors do not trip the breaker. |

-  It never sees `global`/`workstream`/`user` memories, so content written by

-
-The same scheme / no-userinfo / SSRF rules apply to allow-listed hosts —
-this knob only relaxes the same-origin check, not the security gates.
-Each entry is a hostname (no scheme, no path).
-
-### Self-hosted and internal IdPs
-
-By default Turnstone refuses an issuer whose hostname resolves to a
-private or internal address:
-
-```
-OIDCError: endpoint URL resolves to non-public address (10.0.0.5): https://auth.example.site
-```
-
-This is SSRF hardening, not a licensing or product restriction: the OIDC
-flow makes server-side HTTP requests (discovery, JWKS, token exchange),
-and refusing non-public destinations keeps a mistyped or maliciously
-steered issuer from aiming those fetches at internal services. For a
-self-hosted IdP (Keycloak, Authentik, Dex, …) on a private network,
-opt in explicitly in `config.toml`:
-
-```toml
-[oidc]
-allow_private_network = true
-```
-
-or via `TURNSTONE_OIDC_ALLOW_PRIVATE_NETWORK=true` (the env var wins

-The opt-in admits private-range (RFC 1918), unique-local, CGNAT

-services (169.254.169.254) live there, and no legitimate IdP does. The

-**Constraint**: OAuth-MCP servers (`auth_type=oauth_user`) require browser-based user consent. Users must pre-consent via the web UI before any run that cannot drive a browser redirect.
-
-**Affected surfaces**:
-
-- Scheduled workstreams (`turnstone-console` task scheduler).
-- Discord adapter runs.
-- Slack adapter runs.
-- Any future channel adapter without an interactive browser session.
-
-**What happens when consent is missing**:
-
-A tool call against an `oauth_user` server returns a structured `mcp_consent_required` error to the agent. The agent surfaces the deferred work in its output. Turnstone persists a record to `mcp_pending_consent` so the dashboard badge surfaces the deferred consent need to the user on next login.
-
-**Recovery**:
-
-The user opens the dashboard, sees the gear-icon badge counting pending consents, opens the settings modal, clicks Connect for each affected server, and completes the OAuth dance. The pending-consent record is cleared by the OAuth callback handler on success. Subsequent scheduled / channel runs use the freshly-stored token.
-
-**Pre-consent recipe**:
-
-Before scheduling a workstream that depends on an `oauth_user` MCP server, the user should:
-
-1. Open the dashboard.
-2. Open the settings modal (gear icon).
-3. Click Connect on each MCP server the schedule will use.
-4. Confirm consent in the popup.
-
-This stores tokens that the scheduled run will reuse. Refresh-token rotation is handled transparently on the run side; only the first consent requires browser interaction.

-# Personas
-
-A **persona** is a named, reusable bundle attached to a workstream **at
-creation** that controls how its system message is composed and what
-capability envelope it runs with. Personas answer a recurring operational
-complaint: the default composition primes every session for heavy tool use,
-and there was no per-workstream dial to launch a "just write prose" or
-"evidence-first research" session.
-
-A persona is exactly four levers — no more:
-
-| Lever | What it does |
-|---|---|
-| **Base prompt** | Replaces the BASE module of the composed system message. *Only* BASE: ENV, CONTEXT, TOOLS, and POLICIES keep composing, so mandatory [prompt policies](governance.md) ride on top of every persona. Built-in personas source their prose from a repo file; operator personas store it inline — see [Where persona prompts live](#where-persona-prompts-live). |
-| **Tool visibility** | Which tools the session advertises. Tri-state: *unrestricted* (tracks tool growth and MCP catalogs), *no tools* (the TOOLS prompt block self-suppresses and zero definitions go on the wire), or an *exact set* of names. Including `tool_search` in a set makes it **soft** — tools the model discovers through search join the visible set; omitting it makes the set **hard** (the search pathway is disabled entirely). On commercial providers a soft set costs one prompt-cache re-prime per `tool_search` expansion, since each expansion rewrites the wire tool set and recomposes the prompt. |
-| **MCP** | Whether the workstream talks to MCP at all. **Session-wide**: off means no MCP tools for the persona's own hands *or* for in-process task agents, no resource/prompt catalogs, and no listener registrations. This lever expresses infrastructure intent, not behavior shaping. |
-| **Memory** | Whether the persona's **own hands** get memory: recalled-memory injection into the prompt, memory-directed metacognitive nudges, and the `memory` tool. Task agents keep their own envelope, and compaction spill/markers are session mechanics that are never persona-gated. An exact tool set that hides `memory` also mutes those nudges, and the compaction-resume pointer follows `recall`'s visibility. |
-
-Visibility is behavior shaping, **not** a security boundary: any tool call
-that does reach the wire still clears the same approval, judge, and policy
-machinery as always. RBAC and tool policies remain the enforcement layers.
-
-## Snapshot semantics — resolve once, stamp forever
-
-The persona is resolved **once**, at workstream creation, and stamped into
-`workstream_config` as five keys (`persona`, `persona_prompt`,
-`persona_tools`, `persona_mcp`, `persona_memory`). From then on the session
-reads only the stamp:
-
-- **Editing or archiving a persona never changes an existing workstream.**
-  Rehydrate, resume, and post-compaction resume all run from the stamp.
-  A mid-session REPL `/resume` adopts the target workstream's stamp for
-  prompt, tools, and memory; for the MCP lever it can only narrow in
-  place — adopting an MCP-off stamp drops the live MCP surface, while
-  adopting an MCP-on stamp into a session whose persona dropped MCP at
-  construction is refused with an error telling you to reopen the
-  workstream fresh.
-- A workstream outlives its persona — an archived persona keeps labelling
-  the workstreams stamped with it.
-- A partial or unparseable stamp is treated as corruption: session
-  construction fails loudly rather than silently falling back to a default
-  envelope the operator never chose.
-- Workstreams created before personas existed carry no stamp and keep
-  legacy behavior, byte-identical to the `engineer` / `orchestrator`
-  defaults below — with one exception: pre-1.7 workstreams that had
-  `creative_mode` set are converted by migration `063` into full
-  `writer` stamps, so they resume as writing sessions rather than as
-  legacy defaults.
-- Forking (`resume_ws` on create) resumes the source's stamped persona; the
-  fork does not re-resolve.
-
-## Seed personas
-
-Migration `063` seeds six personas. The two per-kind **defaults** carry no
-overrides at all, so a zero-touch launch behaves exactly as it did before
-personas existed:
-
-| Persona | Kind | Base prompt | Tools | MCP | Memory |
-|---|---|---|---|---|---|
-| `engineer` *(default)* | interactive | stock | unrestricted | on | on |
-| `orchestrator` *(default)* | coordinator | stock | unrestricted | on | on |
-| `scribe` | interactive | custom (faithful structuring of given material) | none | off | off |
-| `researcher` | interactive | custom (evidence-first) | `read_file`, `search`, `web_fetch`, `web_search`, `recall`, `memory`, `tool_search` (soft) | off | on |
-| `writer` | interactive | custom (creative writing partner — replaces the removed `/creative`) | none | off | on |
-| `executive` | coordinator | custom (delegate, interrogate plans, judge outcomes) | spawn/inspect/lifecycle tools plus `memory`: `spawn_workstream`, `spawn_batch`, `send_to_workstream`, `wait_for_workstream`, `inspect_workstream`, `list_workstreams`, `list_nodes`, `close_workstream`, `cancel_workstream`, `memory` (hard) | off | on |
-
-Notes:
-
-- `scribe` turns memory off deliberately: recalled memories would
-  contaminate faithful summarization with unrelated context.
-- `researcher`'s set is soft (includes `tool_search`): it starts with
-  read and evidence tools but can pull in others on demand — e.g. load
-  `bash` to run a snippet and verify a calculation. It is evidence-first,
-  not sandboxed; any escalated tool still hits the normal approval path.
-- Coordinator sessions do not merge MCP today, so the MCP lever on
-  coordinator personas is forward-compatible bookkeeping; it bites on
-  interactive workstreams.
-
-## Where persona prompts live
-
-Prompt source is explicit in the persona row — two nullable columns, never both empty:
-
-| `base_prompt_file` | `base_prompt` | Meaning |
-|---|---|---|
-| set (e.g. `scribe.md`) | — | **built-in**: prose lives in `prompts/personas/<file>`, code-owned and PR-reviewed |
-| set | set | built-in with an **operator override** layered on top (the inline text wins) |
-| — | set | **operator** persona, inline prose |
-
-A `CHECK` forbids the both-empty row, so resolution is a plain coalesce —
-`base_prompt ?? load(base_prompt_file)` — with no implicit "inherit the default"
-branch in application logic. `base_prompt_file` is set only by the migration/code
-(the admin API never exposes it): it marks a persona as built-in and blocks
-archive, so `engineer` and `orchestrator` can't be removed. To customise a
-built-in, set `base_prompt` on it (clear it to revert), or create your own persona.
-
-The resolved prompt is **frozen into the workstream at creation** — later edits to
-a built-in's file or an operator's row never change a running workstream; only new
-ones pick up the change. "No persona" is not a state: every workstream is stamped,
-and an empty `persona=` resolves to the kind's `is_default` (`engineer` /
-`orchestrator`).
-
-## Choosing a persona
-
-Every creation surface takes an optional persona; empty always means the
-kind's default (or plain legacy behavior on a database with no personas
-seeded):
-
-- **Web/console**: the persona select on the console launcher, the server
-  webui's new-workstream dialog, and the dashboard composer. Selecting a
-  persona requires **no** `persona.*` permission — the picker feed
-  (`GET /v1/api/personas`) is authenticated-only and returns display fields.
-- **API/SDK**: `CreateWorkstreamRequest.persona` (Python:
-  `create_workstream(persona=...)`; TypeScript: `{ persona: ... }`).
-- **CLI**: `turnstone --persona <name>`. Unknown or disabled names error at
-  startup. `--resume` ignores `--persona` and adopts the resumed
-  workstream's stamp.
-- **Coordinator spawn**: `spawn_workstream` / `spawn_batch` take a
-  `persona` argument, validated when the coordinator prepares the spawn
-  and re-checked by the node that creates the child (children are always
-  interactive-kind). Omitted means the interactive **default** — a child
-  never inherits its parent coordinator's persona.
-- **Sub-agents**: `task_agent` takes a `persona` argument setting the
-  sub-agent's identity and capability envelope (resolved against
-  interactive-kind personas, frozen into the task at prep). Omitted keeps
-  the default autonomous task-agent identity — never the parent's persona.
-
-## How agents discover personas
-
-Agents are told, not expected to guess: the live persona list (enabled,
-interactive-kind — children and sub-agents are always interactive) is
-injected into the `persona` parameter description of `task_agent`,
-`spawn_workstream`, and `spawn_batch` whenever the session's tool surface
-is rendered — session start, MCP catalog change, model-registry reload.
-Each entry carries the name, the default marker, and the persona's
-one-line description so the model can pick by purpose (descriptions drop
-out past 25 personas; the name list always enumerates completely).
-
-A persona created after that render is still reachable — pass its name.
-Every resolve failure enumerates the names currently valid for the kind,
-so a stale list (or a typo) self-corrects on the next attempt.
-
-Resolution is forgiving on all surfaces (they share one rule):
-
-- names match case-insensitively (`Writer` resolves `writer`);
-- an input that uniquely matches a persona's **display name**
-  (case-insensitive, among the kind's enabled personas — display names are
-  not unique, and a same-label persona of another kind neither blocks nor
-  wins) resolves to that persona; an ambiguous match errors, listing the
-  candidate slugs;
-- whatever variant matched, the stamped identity, approval chrome, and
-  wire always carry the canonical `name` slug.
-
-## Authoring (console)
-
-Personas are managed in the console's **Manage → Governance → Personas**
-tab. The admin shelf exposes exactly the four levers plus the kind
-list, the default marker, and archive. Rules:
-
-- `name` is an immutable lowercase slug — and the identifier agents and
-  the CLI launch the persona by (`persona=` on the spawn tools,
-  `--persona` on the CLI); the create shelf says so under **Name**.
-  `display_name` is a list label, editable any time, and deliberately
-  not an identifier (a unique display name happens to resolve, as a
-  forgiveness fallback — don't design workflows around it).
-- Exactly one default per kind, storage-enforced: flipping the flag on a
-  successor demotes the incumbent atomically, defaults are single-kind,
-  and a default cannot be archived.
-- **Archive only** — there is no delete verb, so every stamped
-  workstream's provenance stays explicable.
-
-RBAC: `persona.create` / `persona.read` / `persona.write` gate the admin
-CRUD (`/v1/api/admin/personas`); all three are granted to `builtin-admin`
-by migration `063`, and other roles opt in via role permission overrides.

-## Per-Model Sampling Overrides
-
-The global `model.temperature`, `model.max_tokens`, and `model.reasoning_effort`
-settings serve as cluster-wide defaults. Individual models can override these
-via per-model settings in the `model_definitions` table (admin Models tab).
-
-Resolution order for sampling parameters:
-
-| Priority | Source |
-|----------|--------|
-| 1 (highest) | Per-model override (set in Models tab) |
-| 2 | Global default (set in Settings tab) |
-| 3 | Registry default (code) |
-
-When a per-model override is `NULL` (empty in the UI), the global default is
-used. Switching models via `/model <alias>` re-resolves sampling parameters
-from the new model's overrides or global defaults.
-
-### Responses output controls (per-model)
-
-Models whose capability table declares Responses output controls expose two
-additional fields in the Models create/edit shelf:
-
-| Field | Stored capability | Values | Effect |
-|-------|-------------------|--------|--------|
-| Output verbosity | `verbosity` | `low`, `medium`, `high` | Controls answer length independently of reasoning effort. |
-| Reasoning mode | `reasoning_mode` | `standard`, `pro` | Selects standard or higher-compute Pro execution without changing the model ID. |
-
-An empty selection means provider default and omits the capability key. Known
-GPT-5.6 models inherit support from the built-in table without persisting
-redundant support flags. An OpenAI-compatible model pinned to the Responses API
-can opt in with the `supports_verbosity` and `supports_pro_mode` capability
-tiles. Chat Completions and non-Responses providers do not surface or submit
-these controls.
-
-**Removed settings:** `model.name` and `model.context_window` have been removed
-from ConfigStore. Model names and context windows are now configured per-model
-in the Models tab. A startup warning is logged if these keys appear in
-`config.toml`.
-
-### Reasoning persistence (per-model)
-
-Two boolean flags on `model_definitions` (migration 052) control how
-reasoning text round-trips per model:
-
-| Flag | Default | Effect |
-|------|---------|--------|
-| `surface_persisted_reasoning` | `True` | Surface stored reasoning text on `/history` payloads so a page reload re-renders the reasoning bubble. **Storage of reasoning bytes is independent of this flag** — they ride in `provider_data` regardless. |
-| `replay_reasoning_to_model` | `False` | Send stored reasoning blocks back to the provider on subsequent turns. Capability-gated: only takes effect when the model's `ModelCapabilities.supports_reasoning_replay` is also `True`. Set on canonical OpenAI gpt-5*/o-series and Anthropic Claude entries; unknown / local-server models default to `False` so an operator who flips the flag on a model whose API doesn't understand reasoning replay silently no-ops rather than 400-ing. |
-
-Edit both via the admin Models tab. See the architecture doc for the
-provider-side mechanics (Anthropic `thinking`, OpenAI Responses
-`reasoning` + `include=["reasoning.encrypted_content"]`, synthetic
-`reasoning_text` for Chat Completions / vLLM / llama.cpp / Gemini-compat).
-
-### Task agent overrides
-
-`task_agent` sub-sessions resolve independently from the conversation model
-so operators can pick a cheaper/faster model for autonomous loops:
-
-| Setting | Purpose |
-|---------|---------|
-| `model.task_alias` | Alias used for `task_agent` sub-sessions. Falls back to `[model].agent_model` in config.toml, then the session's active model. |
-| `model.task_effort` | Reasoning effort for `task_agent`. Empty string means "inherit from the session". |
-
-Both are live-editable from the Settings tab and take effect on the
-next sub-agent invocation — no restart required.

-description: Use this skill when the user wants to import or migrate conversation history from another LLM chat or coding tool (e.g. ChatGPT, Claude.ai, Cursor, Copilot Chat, Aider, Gemini, a custom JSON export) into Turnstone. The skill teaches Turnstone's destination contracts — workstream identity, the OpenAI-shaped message rows, tool-call/result pairing, provider-fidelity blobs, attachments, and archive-vs-resumable choice — so the agent can map any source format onto them. Trigger phrases: "import my chats", "migrate this transcript into Turnstone", "bring my Claude.ai history over", "load this export as a workstream".
-version: 1.0.0

-
-# Importing Conversation History into Turnstone
-
-## Overview
-
-Source formats vary; the destination does not. Your job is to translate whatever the user hands you (JSON dump, ZIP export, scraped HTML, screenshot OCR, raw transcript) into Turnstone's internal shape: **one workstream row** plus an ordered sequence of **conversation rows** in OpenAI message format. This skill documents the destination so you can write a correct mapper for any source.
-
-Two questions to settle with the user before writing anything:
-
-1. **Archive or resumable?** An archive ("saved" workstream — `state="closed"`) is read-only history. A resumable workstream (`state="idle"`) lets the user continue the conversation; this only works cleanly when the source LLM matches a Turnstone-supported provider/model and tool definitions still resolve.
-2. **One workstream per source thread, or merge?** Default to one-to-one unless the user explicitly asks to merge.
-
-Default to **archive** when in doubt — resuming a foreign transcript with mismatched tool schemas or stale provider signatures will fail at the next turn.
-
-## Turnstone Data Model (the destination)
-
-Two tables carry the conversation:
-
-### `workstreams` (one row per imported thread)
-
-| Column | Required | Notes |
-|---|---|---|
-| `ws_id` | yes | 32-char lowercase hex. Auto-generate with `secrets.token_hex(16)` if you don't already have one. **First 4 hex chars are the routing bucket** — see "Identity & Routing" below. |
-| `name` | yes | Short title. Pull from source thread title; fall back to first ~60 chars of first user message. |
-| `state` | yes | `"closed"` for archive, `"idle"` for resumable. Never set `"running"` on import. |
-| `kind` | yes | `"interactive"` for normal threads. Do NOT use `"coordinator"` for imports — that's reserved for cluster-spawned coordinator workstreams. |
-| `parent_ws_id` | no | Leave NULL. Only set if you're importing a coordinator-spawned subtree and re-parenting it; rare. |
-| `user_id` | yes | Owner. Must exist in `users`; importer must know which Turnstone user owns the imported history. |
-| `node_id` | yes (multi-node) | Denormalized cache of the node that owns this `ws_id`'s bucket. Single-node deployments can leave it NULL or set it to the only node. |
-| `alias` | no | Human-typeable short name. Optional; must be unique cluster-wide if set. |
-| `title` | no | Auto-titled later by the LLM; safe to leave NULL on import. |
-| `skill_id`, `skill_version` | yes | Default `""` and `0` unless the source thread was scoped to a Turnstone skill. |
-| `created`, `updated` | yes | ISO8601 strings. Use the source's first/last message timestamps when available. |
-
-### `conversations` (many rows per thread, ordered by `id`/`timestamp`)
-
-| Column | Notes |
-|---|---|
-| `ws_id` | The workstream this row belongs to. |
-| `timestamp` | ISO8601 string. Preserve source timestamps; fall back to monotonically increasing values if unknown. **Order is canonical via `id` (autoincrement), not `timestamp`** — but always insert in conversational order so both agree. |
-| `role` | One of `system`, `user`, `assistant`, `tool`, `developer`. See role mapping below. |
-| `content` | Text. May be NULL for assistant rows that are *only* tool calls. |
-| `tool_name` | Set on `role="tool"` rows (the tool whose result this is). NULL otherwise. |
-| `tool_call_id` | Set on `role="tool"` rows (matches the assistant row's `tool_calls[].id`). NULL otherwise. |
-| `tool_calls` | JSON-encoded list, on `role="assistant"` rows that issued tool calls. OpenAI shape — see "Tool Calls" below. |
-| `provider_data` | JSON blob preserving provider-native content blocks (Anthropic `signature`, Gemini `thought_signature`, etc.). Optional; only matters for **resumable** imports against the same provider. Skip for archives. |
-
-The internal format is **OpenAI-shaped**, even when the source was Anthropic or Gemini. Providers translate at their own API boundary; storage stays uniform.
-
-## Identity & Routing (`ws_id`)
-
-- `ws_id` is **32-char lowercase hex** (i.e. `secrets.token_hex(16)`).
-- The **routing bucket** is `int(ws_id[:4], 16)` — the first 4 hex chars place this workstream on a specific node via the consistent hash ring.
-- For multi-node imports: either insert through the console's routing proxy (which forwards to the owning node), or generate `ws_id`s and write directly to each node's database in batches grouped by bucket.
-- For single-node imports: bucket math is irrelevant; any `ws_id` works.
-- **Do not reuse the source platform's IDs as `ws_id`** unless they happen to be 32-char hex. Generate fresh; if you need the old ID for traceability, store it in `workstream_config` under a key like `import.source_id`.
-
-## Recommended Import Path
-
-Three options, in order of preference:
-
-### 1. Storage protocol (recommended for full history)
-
-Use `turnstone.core.storage.Storage.save_messages_bulk(rows)`. This is the canonical bulk-insert primitive and bypasses the LLM round-trip entirely.
-
-```python
-from turnstone.core.storage import get_storage  # construct via the same path the server uses
-
-storage = get_storage(...)  # see turnstone.core.storage.__init__ for the project's wiring
-
-storage.create_workstream(  # or whatever the project's exposed creator is — check turnstone/core/storage/_protocol.py
-    ws_id=ws_id,
-    user_id=user_id,
-    name=name,
-    state="closed",
-    kind="interactive",
-    ...
-)
-
-storage.save_messages_bulk([
-    {"ws_id": ws_id, "role": "user", "content": "Hello"},
-    {"ws_id": ws_id, "role": "assistant", "content": "Hi! What can I help with?"},
-    {"ws_id": ws_id, "role": "assistant", "content": None,
-     "tool_calls": json.dumps([{"id": "call_1", "type": "function",
-                                "function": {"name": "search", "arguments": "{\"q\":\"x\"}"}}])},
-    {"ws_id": ws_id, "role": "tool", "tool_name": "search", "tool_call_id": "call_1",
-     "content": "result text"},
-    # ...
-])
-```
-
-`save_messages_bulk` handles `timestamp` and the workstream's `updated` column internally, so you don't need to compute them per row. **Verify the exact creator signature** by reading `turnstone/core/storage/_protocol.py` — table layout has shifted across migrations and the Storage protocol is the source of truth.
-
-### 2. SDK `create_workstream(resume_ws=...)` (when the source is already a Turnstone workstream)
-
-Only useful for *Turnstone → Turnstone* re-parenting. Not relevant for foreign sources.
-
-### 3. SDK `create_workstream(initial_message=...)` + `send()` per turn (last resort)
-
-Only fits archives where the source had **no tool calls** and you don't care about preserving assistant turns verbatim. Each `send()` triggers a real LLM round-trip, which is expensive and rewrites assistant content. Don't use this for full history.
-
-## Role Mapping
-
-Common source-role conventions and how they map to Turnstone:
-
-| Source role | Turnstone `role` | Notes |
-|---|---|---|
-| `user`, `human` | `user` | Direct map. |
-| `assistant`, `ai`, `model`, `bot` | `assistant` | Direct map. |
-| `system` | `system` | Preserve only if it's content the user wrote (custom instructions). Drop boilerplate provider preambles — Turnstone composes its own system message. |
-| `developer` (OpenAI o-series) | `developer` | Preserve. |
-| `tool`, `function`, `tool_result` | `tool` | Must carry `tool_name` and `tool_call_id` matching the prior assistant row's `tool_calls[].id`. |
-| `tool_use` (Anthropic) | `assistant` with `tool_calls` | Anthropic emits tool calls *inside* an assistant message; flatten to OpenAI shape. |
-| `human_feedback`, `revision` | `user` | Treat as a follow-up user turn. |
-
-## Tool Calls (the most error-prone part)
-
-Turnstone stores tool calls in OpenAI's nested-function shape on the assistant row, and matches them with `role="tool"` result rows by `tool_call_id`.
-
-### Assistant row with tool calls
-
-```json
-{
-  "role": "assistant",
-  "content": null,
-  "tool_calls": [
-    {
-      "id": "call_abc123",
-      "type": "function",
-      "function": {
-        "name": "search_web",
-        "arguments": "{\"query\":\"turnstone import\"}"
-      }
-    }
-  ]
-}
-```
-
-`tool_calls[].function.arguments` is **a JSON-encoded string**, not an object. Source formats commonly get this wrong — Anthropic stores arguments as a parsed object, Gemini as a struct. Always re-serialize to a string.
-
-### Tool result row
-
-```json
-{
-  "role": "tool",
-  "tool_name": "search_web",
-  "tool_call_id": "call_abc123",
-  "content": "..."
-}
-```
-
-Pairing rules:
-- Every assistant `tool_calls[].id` MUST be followed by exactly one `role="tool"` row with the matching `tool_call_id`, before the next user/assistant turn.
-- If the source dropped the tool result (cut-off transcript), insert a synthetic `role="tool"` row with `content="[tool result missing in source]"` to keep the chain valid. An assistant row with an unanswered `tool_calls[].id` will break replay and any LLM round-trip.
-- Multi-tool assistant turns: one `role="tool"` row per call, in any order, all before the next non-tool row.

-If the source used opaque tool IDs that aren't unique within a thread (some platforms reuse them), regenerate with a stable scheme like `f"call_{i}"` where `i` is a per-thread counter. Update both the assistant and tool rows together.
-
-## Provider Fidelity (`provider_data`)
-
-Skip this entirely for **archive** imports.
-
-For **resumable** imports against the same provider, populate `provider_data` to preserve provider-specific tool-call metadata that the next API round-trip will require:
-
-- **Anthropic**: `signature` field on thinking blocks; required for round-tripping extended-thinking responses.
-- **Gemini**: `thought_signature` on tool calls; required for fidelity.
-- **OpenAI**: typically nothing to preserve.
-
-The runtime-side dict key is `_provider_content` (a list of provider-native blocks); the persisted column is `provider_data` (the same list, JSON-encoded). If you don't have provider-native blocks from the source — and you usually won't, because a foreign export won't include them — leave `provider_data` NULL. The first new turn will succeed without it, but the previous assistant turn's reasoning won't replay back to the model.
-
-## Attachments
-
-If the source thread had image or file attachments:
-
-- **Size limits**: images ≤ 4 MiB, text documents ≤ 512 KiB. Reject or downsample anything bigger.
-- **Allowed types**: server validates magic bytes for images and UTF-8-decodes for text. Binary blobs that aren't images won't pass.
-- **Lifecycle**: pending → reserved → consumed. For imports, the cleanest path is to upload as pending and immediately consume by attaching to the relevant `conversations.id`.
-
-Two import paths:
-
-1. **Bulk-insert + post-attach**: insert messages first, get back the assistant/user `conversations.id`, then write `workstream_attachments` rows linking the file to `message_id`.
-2. **SDK multipart create**: `create_workstream(attachments=[...], initial_message=...)` for the *first* turn only — the server reserves and consumes them onto that turn. Doesn't help for mid-thread attachments.
-
-For full-history imports with multiple attachments at different turns, path (1) is the only option.
-
-## Validation Checklist
-
-Before declaring success, verify:
-
-- [ ] `ws_id` is 32-char lowercase hex.
-- [ ] `workstreams` row exists with the right `user_id`, `state`, `kind`.
-- [ ] Conversation rows are inserted **in order** (autoincrement `id` will reflect insert order).
-- [ ] Every assistant `tool_calls[].id` has a matching `role="tool"` row with the same `tool_call_id`.
-- [ ] `tool_calls[].function.arguments` is a JSON-encoded **string**, not a parsed object.
-- [ ] First message is typically `role="user"` (not `system`) — Turnstone composes its own system prompt at runtime.
-- [ ] No empty assistant rows (`content=NULL` AND `tool_calls=NULL` is invalid).
-- [ ] If multi-node: the `ws_id`'s bucket maps to a node that exists; `workstreams.node_id` matches.
-- [ ] Round-trip test: run `Storage.load_messages(ws_id)` and confirm the reconstructed list matches what you inserted (modulo timestamps).
-
-## Anti-patterns
-
-- **Don't import the source provider's system prompt verbatim.** Provider boilerplate ("You are Claude...", "You are ChatGPT...") will conflict with Turnstone's composed system message and confuse the model on resume. Drop it; preserve only user-authored custom instructions.
-- **Don't preserve foreign tool definitions as Turnstone tools.** If the source had custom tools that don't exist in Turnstone, the assistant rows that called them are still valid history (archive), but the workstream is **not resumable** — mark `state="closed"`.
-- **Don't fabricate `tool_call_id`s without re-pairing.** Mismatched ids silently break the replay chain on the next turn.
-- **Don't skip the `tool_name` field on `role="tool"` rows.** Some load paths use it for display and audit; NULL there will render as "unknown tool".
-- **Don't write through the LLM (`send()` per turn) for full history.** It's expensive, rewrites assistant turns, and rate-limits will bite long imports.

-## Browser access (dashboard HTTPS)
-
-The mTLS above secures **service-to-service** traffic (node↔node, collector and

-must, because it is the cluster's ACME bootstrap endpoint: new nodes fetch
-`/acme/ca.pem` and provision their first cert over HTTP, before they have the CA
-to verify TLS. So the console cannot be HTTPS-only on its port.
-
-To put the **browser → console** hop on HTTPS, terminate TLS at a reverse proxy
-in front of the console. The dev stack (root `compose.yaml`) ships a `caddy`
-service that does exactly this — and it's the only published entry point, so the
-dashboard is HTTPS by default:
-
-```bash
-docker compose up
-# dashboard: https://localhost:${CONSOLE_HTTPS_PORT:-8443}
-```
-
-The production stack (`turnstone/deploy/compose.yaml`) bundles the same `caddy`
-service, so the dashboard is HTTPS there too. For a real domain and a publicly
-trusted cert, point Caddy at Let's Encrypt by editing `turnstone/deploy/Caddyfile`.
-
-```
-browser  --h2 / HTTPS-->  caddy:443  --h1.1 / HTTP-->  console:8090
-```
-
-Caddy uses its **own local CA** (`tls internal`, see `turnstone/deploy/Caddyfile`), so the
-setup is self-contained with no dependency on the console's ACME path. Trust the
-local root once to silence the browser warning:
-
-```bash
-docker compose exec caddy \
-  cat /data/caddy/pki/authorities/local/root.crt   # import into your OS/browser
-```
-
-**Can Caddy get its cert from the console's internal CA instead?** Technically
-yes — the console exposes a real ACME directory (`/acme/directory`) with
-auto-approval, so Caddy's `tls { ca http://console:8090/acme/directory }` would
-mint a cert for any name. It's not recommended as the default: lacme's ACME
-responder is built for turnstone's own client (interop with Caddy's client is
-unverified), it couples Caddy startup to the console, and the browser must trust
-a private CA either way — so it buys nothing over `tls internal`. For a publicly
-trusted cert (no warning), point Caddy at Let's Encrypt with a real domain
-instead.

-
-### Container healthcheck under mTLS
-
-An mTLS listener rejects plain-HTTP probes at the socket, so
-`docker/healthcheck.py` falls back to HTTPS when the plain probe fails:
-it presents the node's own cert as the client cert and pins the cluster
-CA, using the PEM files the server writes at boot under
-`$TURNSTONE_TLS_PEM_DIR` (default `<tmpdir>/turnstone-tls`). The probe
-dials `localhost` for the TLS attempt — the internal CA issues DNS SANs
-only, so a literal-IP URL would fail verification. Cert renewal rewrites
-the PEM dir alongside the live listener swap, so the probe's client cert
-never outlives the served cert. With TLS disabled the plain probe succeeds
-and the PEM directory is never consulted. On bare metal with multiple

-`web_search` can use an external **reranker** to re-order the backend's result pool by relevance to the query before returning the top hits. Turnstone runs no reranker model itself; it POSTs to a Cohere/Jina-compatible `/rerank` endpoint (self-hosted [vLLM](https://docs.vllm.ai) / [TEI](https://github.com/huggingface/text-embeddings-inference) / llama.cpp, or hosted Cohere/Jina/Voyage).
-
-**Disabled by default.** In the console **Models** tab, add a model definition whose `base_url` is a Cohere/Jina-compatible `/rerank` endpoint and whose capabilities include `{"supports_rerank": true}`, then select it under **Models → Roles → Reranker**. It's managed like every other model (write-only key, enable/disable, calibration). The reranker is purely this per-model definition — there is no global `rerank_url`-style endpoint setting.
-
-The `rerank_web_search` toggle defaults on once a reranker is selected. If the endpoint is unreachable or errors, web_search falls back silently to the backend's native result order — reranking never makes a search fail.
-
-When `rerank_bm25` is enabled, the candidate text for memory, tool, and skill retrieval (memory name/description/content and tool/skill names + descriptions) is also sent to the rerank endpoint — a self-hosted endpoint (vLLM/TEI/llama.cpp) keeps it on your infrastructure, a hosted provider (Cohere/Jina/Voyage) sends it off-box.
-
-**Serving a Qwen3-Reranker with vLLM.** The model is instruction-aware, so vLLM **must** apply its chat template — pass `--chat-template` explicitly. Without it the bare query produces near-random scores and reranking actively *hurts* retrieval (verified: an irrelevant passage outscored the correct one):
-
-```bash
-vllm serve /models/Qwen3-Reranker-0.6B \
-  --runner pooling \
-  --hf-overrides '{"architectures":["Qwen3ForSequenceClassification"],"classifier_from_token":["no","yes"],"is_original_qwen3_reranker":true}' \
-  --chat-template /models/Qwen3-Reranker-0.6B/chat_template.jinja \
-  --served-model-name qwen3-reranker --port 8000
-```
-
-Then add a reranker model in the **Models** tab with `base_url` `http://vllm:8000/rerank` (model name `qwen3-reranker`) and select it under **Models → Roles → Reranker**.
-
-For an endpoint that does *not* apply the model's template, set `rerank_instruction` instead — Turnstone then wraps each query as `<Instruct>: {instruction}` / `<Query>: {query}` (Qwen3's own default is `Given a web search query, retrieve relevant passages that answer the query`). Use the chat template **or** the instruction, not both (they double-wrap).
-
-**Picking `rerank_bm25_threshold`.** The relevance floor that gates proactive memory injection is a probability in `[0, 1]`, but the right value differs per model (a sharp 0.6B reranker may want ~0.95; a broader 4B ~0.33). Calibrate it against your endpoint:
-
-```bash
-turnstone-admin rerank-calibrate           # probe the endpoint, recommend a floor
-turnstone-admin rerank-calibrate --apply   # ...and write tools.rerank_bm25_threshold
-```
-
-It reports the score scale, whether the endpoint cleanly separates relevant from irrelevant probes (a **"no clean separation"** result flags a mis-served or weak reranker), and the suggested floor. Leave the threshold at `0` to rerank-without-filtering.

-
-- **What it does**: Resolves the target to bytes (URLs fetch through the same
-  SSRF-guarded path as `web_fetch`, screened per redirect hop, honoring the
-  same `tools.allow_private_network` opt-in), classifies the
-  content, stores it content-addressed against the workstream, and opens the
-  frontend preview pane beside the conversation: web pages render in a fully
-  sandboxed iframe (no scripts, opaque origin), PDFs in the browser viewer,
-  images inline, CSV/TSV/JSON as a sortable table, text/markdown rendered. A
-  previewed web page loads none of its remote images or styles by default, so
-  opening it never reveals the viewer to the page's site; a toggle in the pane
-  header turns remote content back on for that preview. The
-  model receives only a one-line confirmation — to reason about content, use
-  `web_fetch` / `read_file` instead. Preview content is size-capped per kind
-  (pages 4 MB, PDFs 32 MB, images 4 MB, tables 2 MB, text 512 KB) and GC'd

-# Understone
-
-A small, multiplayer, BBS-style **ANSI door game** served over the Model
-Context Protocol (MCP). It is a text RPG in the spirit of *Legend of the Red
-Dragon* — explore an overworld of box-drawing maps, fight wandering monsters,
-shop and rest in town, and descend a dungeon — except the "door" is an MCP
-server and the player drives it by talking to an AI assistant.
-
-The server is the rules engine and the single source of truth. Players share
-**one persistent world**: your assistant calls tools, the server returns
-authoritative frames and facts, and the assistant narrates the story around
-them.
-
-This is a self-contained reference example. It depends only on `mcp` — there
-is no dependency on Turnstone itself — so it runs against any MCP client.
-
-## How to play
-
-There is **no prompt to paste and no persona to configure**. The tool schema
-is the whole interface. Once the server is registered with your assistant:
-
-1. Tell your assistant you'd like to play an ANSI door game / text dungeon
-   RPG (it can discover the tools by name and description).
-2. The assistant calls `door_help` to learn how to run the world, then
-   `door_join` with your adventurer's name.
-3. Play unfolds as a conversation: "head east", "fight it", "rest at the inn".
-
-Everything the assistant needs to run the game well is returned by
-`door_help`.
-
-## Gameplay
-
-A run is a little RPG loop, played a bit each day:
-
-- **Explore** the overworld of box-drawing maps. Walking is free, but the wild
-  country has texture — a step may turn up a wandering monster, a purse of
-  gold, a healing spring, a small trap (which can never kill you), or a scrap
-  of old Vale lore. Only one such find happens per move, and the non-combat
-  ones don't interrupt your walk.
-- **Fight, shop, and heal** in and around town. Fighting and descending one
-  rung of the dungeon each spend one of your daily turns; resting, shopping and
-  moving do not.
-- **Delve the deep, a rung at a time.** The dungeon is a ladder of guardians:
-  each `descend` faces the next one past your deepest and either advances your
-  depth or bounces you home (your depth persists either way). Carry a few
-  **potions in your satchel** — `quaff` the strongest when you choose, and if a
-  fight would kill you the satchel saves you automatically, the elixir burning
-  down your throat at death's edge. Clearing a rung also yields **forge ore**,
-  which rides the satchel (a won forest fight sometimes turns up a little, too).
-- **Forge an edge — with gold AND ore.** At the shop's **forge** you can add a
-  +1 edge to your equipped weapon or armour, up to a cap, each step dearer than
-  the last. A step costs gold *and* the ore you won in the deep — so the forge is
-  fed by descending, not just by a fat purse. Watch, too, for the **rare beasts**
-  that prowl the forest: felling one is Herald news and always drops a draught.
-- **Win the game** by slaying **the Wyrm Below**. Once your hero is seasoned
-  enough AND has plumbed the deep to its floor, `challenge` it at the dungeon. A
-  victory frees the Vale, carves your run into the **Hall of Legends**, and — in
-  the tradition of the classic BBS door games — begins a new life: your
-  character resets to first-day gear and stats but keeps a permanent ★ for every
-  Wyrm slain, ready to do it all again.
-- **Read the news.** `door_log` is the **Understone Herald**, a shared
-  broadsheet of notable deeds across the whole world — who joined, who rose a
-  level, who was dragged home by a goblin, and who freed the Vale.
-- **Make it social.** It is a shared world, so you can touch other players.
-  `ambush` a rival who has not yet acted today — a classic
-  style player-kill that robs a sleeping foe of some gold, except the surest
-  defence is simply to take your own turn (an active player is awake and can't
-  be caught). Lose the ambush and *you* are the one who flees, shamed on the
-  feed. `post` a private note another player reads on their next visit (it
-  never reaches the public Herald). Or `gamble` a little gold at the inn's dice
-  against the house. Ambush spends a turn; mail and dice do not.
-- **Bank your coin.** The inn keeps a strongbox: `deposit` gold into the
-  **vault** and `withdraw` it later (no turn either way). Banked gold is **safe
-  from ambush** — a sleeping-robber only ever lifts what you carry — and it is
-  the one thing that **survives a Wyrm-win reset**, carrying wealth across runs.

-## Installation
-
-This example uses [`uv`](https://docs.astral.sh/uv/). From the example
-directory:
-
-```bash
-cd examples/door-game
-uv venv
-uv pip install -e .
-```
-
-That installs the `understone` entry point into the environment.
-
-To run the tests and quality gates:
-
-```bash
-uv pip install -e ".[test,dev]"
-uv run pytest
-uv run ruff check .
-uv run ruff format --check .
-uv run mypy understone/
-```
-
-## Running the server
-
-By default the server speaks the **stdio** transport, which is how MCP clients
-launch a per-session subprocess:
-
-```bash
-understone
-```
-
-To host one shared world over HTTP for several clients, run the
-**streamable-http** transport as a single long-lived process:
-
-```bash
-UNDERSTONE_TRANSPORT=streamable-http understone
-```
-
-### Environment variables
-
-| Variable | Default | Description |
-|----------|---------|-------------|
-| `UNDERSTONE_DB` | `./understone.db` | SQLite database file for the world's state. |
-| `UNDERSTONE_WORLD` | _(packaged pack)_ | Directory of a content pack to load instead of the bundled Vale of Understone. |
-| `UNDERSTONE_TRANSPORT` | `stdio` | `stdio` or `streamable-http`. |
-| `UNDERSTONE_HOST` | `127.0.0.1` | Bind host (streamable-http only). |
-| `UNDERSTONE_PORT` | `8077` | Bind port (streamable-http only). |
-| `UNDERSTONE_PATH` | `/mcp` | HTTP path for the MCP endpoint (streamable-http only). |
-
-## The Watch — a live spectator view
-
-When the server runs under the **streamable-http** transport, it also serves a
-read-only **Watch** page: the lobby TV of the Vale. Point a browser at
-
-```
-http://127.0.0.1:8077/watch
-```
-
-(the host and port follow `UNDERSTONE_HOST` / `UNDERSTONE_PORT`). It is a
-period **CRT spectator console** — a green-and-amber phosphor map of the whole
-world with every adventurer's `☻` marker, a live **Understone Herald** feed, the
-**Hall of Legends**, and a roster of who is currently abroad. It refreshes every
-couple of seconds; if it loses contact it dims and reads `SIGNAL LOST` until the
-server returns. The console's palette follows the pack: a world may pick its own
-CRT colour with `settings.watch_theme` (`phosphor` green, `amber` gold, `ice`
-blue, `ember` red), defaulting to the Vale's green if it says nothing.
-
-The Watch is **strictly read-only**. Input never flows through it — there are no
-controls, no forms, nothing that can change the world. It reads the same shared
-state the tools do and paints it; that is all. There is no authentication, in
-keeping with the rest of this easter-egg server (see the safety note below), so
-treat the page as you would the MCP endpoint itself.
-
-> _Screenshot: the Watch console — a phosphor-green overworld map with amber
-> `☻` markers, the Herald feed and Hall of Legends down the right-hand rail.
-> (Image placeholder; run the server and open the URL to see it live.)_
-
-When the Watch is up, the `door_join` welcome and the `door_help` manual both
-print its URL so players (and the assistant narrating for them) know it exists.
-If you bind to `0.0.0.0` to share the world across a network, advertise a host
-that browsers can actually reach (your machine's LAN address or hostname) rather
-than `0.0.0.0` itself — the link is composed from `UNDERSTONE_HOST`.
-
-## Authoring worlds
-
-The Vale of Understone is just the *bundled* world. The whole game — its map,
-monsters, economy, and endgame — is a **content pack**: a directory of six JSON
-files the server loads at start. Nothing about the Vale is privileged; point
-the server at another pack and it runs that world instead. This is the seam
-where the game becomes its own authoring target: a pack is plain data, so a
-person *or an LLM* can write one, and the same zero-setup philosophy that makes
-the game playable with no prompt makes it **authorable with no code**.
-
-The loop has these commands:
-
-```bash
-understone newpack mypack        # scaffold a pack (copies the Vale as a template)
-# ...edit or LLM-generate the JSON in mypack/ to describe your world...
-understone validate mypack       # check it; prints a report or names what's wrong
-understone simulate mypack       # play a greedy bot through it and measure the balance
-UNDERSTONE_WORLD=mypack understone   # serve your world
-understone worlds                # list the bundled worlds and whether each is sound
-```
-
-`newpack` writes a starting template plus an `AUTHORING.md` manual — the
-file-by-file schema, the enforced limits, and design guidance — written to be
-followed cold by a model. `validate` loads the pack through exactly the same
-hardened loader the server uses and either prints a summary ending **"This pack
-is sound. The door stands open."** or fails with one precise line naming the
-file, the row, and the field at fault.
-
-`simulate` is the **balance instrument**: it drives a deliberately simple,
-greedy bot through the *real* game — the same `join`/`move`/`action` calls the
-tools make — over a seeded RNG and an injected clock, then prints a report
-(final level, gold earned, fights fought, rungs cleared, whether and when the
-Wyrm fell). It is a tuning probe, not a player to admire: it answers "is this
-world *shaped* right, and is it *winnable*?". Pass `--days N`, `--seed S`, or
-`--seeds K` for a multi-seed sweep with means and spreads. `worlds` lists every
-bundled world — the default Vale plus any alternate packs shipped under
-`understone/world/packs/` — loading each so it can report it as sound or flawed.
-
-**A second bundled world: The Cinder Wastes.** Understone ships a second world
-alongside the Vale, in `understone/world/packs/cinder-wastes/` — a volcanic
-ash-and-slag map whose Watch page glows ember-red instead of the Vale's green
-phosphor. It is the pipeline's own dogfood: it was authored **by an LLM working
-only from `AUTHORING.md` and the `validate` loop**, with no engine code touched,
-then bundled verbatim. `understone worlds` lists it as sound, and
-`understone simulate understone/world/packs/cinder-wastes --days 50 --seeds 3`
-shows the greedy bot taking its Magma Wyrm — the end-to-end proof that a world
-described purely as data, from the manual alone, is genuinely playable to
-victory. Serve it with
-`UNDERSTONE_WORLD=understone/world/packs/cinder-wastes understone`.
-
-Packs are validated **hard** at load: every map glyph must render as exactly
-one terminal column (no fullwidth runes, no emoji, no combining marks — the
-frames are box-drawing rectangles) and may not collide with the frame's
-box-drawing lines or the player markers, dimensions and counts are bounded,
-display names are length-checked, and every cross-reference (a legend
-character, a starting item, the boss monster, a dungeon tier) must resolve. The
-loader also pins the rules that keep the endgame coherent: a world has exactly
-one boss, and a dungeon tier's lead monster (its fixed rung guardian) may not be
-a rare. Because packs are now routinely untrusted, generated output, those error
-messages are not a nuisance — they are the **feedback loop**. Iterate against
-them until the door stands open.
-
-## Registering with Turnstone
-
-Understone is an ordinary MCP server, so it plugs into Turnstone's MCP client
-config two ways.
-
-**Stdio (per-session subprocess).** Turnstone launches the `understone`
-command for each session. Each session gets its own subprocess, so for a
-truly shared world prefer the HTTP form below; stdio is simplest for solo
-play.
-
-```toml
-[mcp.servers.understone]
-command = "understone"
-
-[mcp.servers.understone.env]
-UNDERSTONE_DB = "/var/lib/understone/world.db"
-```
-
-**Streamable-HTTP (one shared world).** Run a single Understone process with
-`UNDERSTONE_TRANSPORT=streamable-http` and point every client at its URL. This
-is the right setup for multiplayer: one process, one database, one world that
-all adventurers share.
-
-```toml
-[mcp.servers.understone]
-url = "http://localhost:8077/mcp"
-```
-
-> **Operator note.** For multiplayer, start exactly one shared process —
-> `UNDERSTONE_TRANSPORT=streamable-http understone` — and have all clients use
-> the url form. The world lives in a single SQLite file written by that one
-> process.
-
-## The tools
-
-| Tool | What it does |
-|------|--------------|
-| `door_help` | The game-master manual. Start here. |
-| `door_join` | Create or resume an adventurer; returns the opening map. |
-| `door_status` | The character sheet (read-only). |
-| `door_look` | Redraw the current view — overworld map or location menu. |
-| `door_move` | Walk the overworld (free; no daily turn spent). |
-| `door_action` | Context verbs: fight, flee, ambush (a rival), rest, deposit/withdraw (the inn vault), buy, sell, forge (a +1 edge, gold + ore), heal, gamble (inn dice), descend (one rung), challenge (the Wyrm), post (mail another player), quaff (a carried potion), leave. |
-| `door_log` | The Understone Herald — the shared feed of notable deeds. |
-| `door_rank` | The leaderboard, plus the Hall of Legends (★ marks Wyrm kills). |
-| `door_bestow` | Game-master grant of a little gold/healing for a story beat. |
-
-## A note on identity and safety
-
-This example is an **easter egg**, not a hardened service. Identity is
-**self-asserted**: a "player" is just a name passed to the tools, and there is
-**no authentication** — anyone who can reach the server can act as any name.
-That is fine for a shared toy world among people who trust each other, and
-deliberately out of scope for a game. Do not store anything sensitive in it,
-and if you expose the HTTP transport beyond localhost, put it behind whatever
-access control your environment already provides.
-
-The game master's `door_bestow` channel can only grant small, capped amounts
-of in-game gold and healing — never items, never turns — and every grant is
-written to the public in-world log, so its reach is bounded by design.

-"""Game façade integration tests over the shipped world.

-Drives a full session against a temp store, a frozen clock, and a seeded
-RNG: join -> status -> look -> move -> action(buy/rest/fight) -> log ->
-rank -> bestow. Persistence is exercised by reopening the store.
-
-Negative-test discipline (turn guard and bestow cap):
-  Two guards are pinned by assertions here. To confirm each assertion has
-  teeth, the implementer temporarily reverted the guard line and observed
-  the matching test FAIL, then restored it:
-
-  * Turn guard (engine/turns.py spend_turn): replacing
-    ``if player.turns_left <= 0: return False`` with ``return True``
-    let fighting continue past the daily budget — ``test_turn_budget_blocks``
-    then failed on the "spent for today" assertion. Restored.
-  * Bestow cap (game.py bestow): removing the ``if cost > remaining``
-    refusal let an over-budget bestowal through — ``test_bestow_cap_refuses``
-    then failed on the unchanged-gold assertion. Restored.
-  * Sanitizer control-char guard (game.py _sanitize): disabling the
-    ``not cleaned.isprintable()`` clause let a newline-injected name create a
-    player row and a public event — ``test_join_rejects_control_char_name``
-    then failed. Restored. (See the comment block above the hygiene tests.)
