chore: bump version to 1.6.9

- The guard snapshotted live threads by `Thread.ident`, but idents are
  recycled after a thread exits — a new leaked thread reusing an exited
  thread's ident would be mistaken for pre-existing and missed (false
  negative). Snapshot the Thread OBJECTS and compare by identity instead.
- Fix the `serve` fixture docstring: the factory returns the ephemeral
  port, not the server.

-## [Unreleased]
-
-### Added
-
-- **Compaction is visible now: lifecycle events, a progress bar, and a
-  persistent transcript card.** Context compaction (manual `/compact` and
-  auto) emits a first-class `compaction` SSE event
-  (`start` / `progress` / `end` — see the API reference) instead of loose
-  info lines. The web UI renders an in-transcript card with a real progress
-  bar (determinate `part k of N` during chunked summarization, indeterminate
-  for single-call compactions) that settles into a result card — token delta
-  plus the summary behind a fold — in both the interactive pane and the
-  coordinator viewer. The result survives reloads: the persisted compaction
-  marker now projects through `/history` as a `role="system"`,
-  `source="compaction"` entry (resume/export/search unchanged), stamped with
-  the end event's id so repaint and SSE replay can't double-render. The
-  marker's `meta` additionally records `before_tokens` / `after_tokens` /
-  `trigger`. Python and TypeScript SDKs gain a typed `CompactionEvent`.
-
-- **One provider transport: every model call now streams (#831).**
-  The per-adapter non-streaming entry (`create_completion`) is retired;
-  single-shot lanes — judges, titles, compaction, web-fetch extraction,
-  perception, eval, optimizer — sample through the same streaming entry
-  the chat loop uses and accumulate via one shared drain, so request
-  shaping can no longer drift between the two consumption styles. Two
-  operator-visible consequences: long single-shot generations (a thinking
-  model composing a title, a slow local judge) no longer sit in a single
-  blocking read that can hit client read-timeouts — the same reason the
-  Anthropic adapter already streamed internally — and judge timeouts now
-  *abort* the underlying HTTP read instead of abandoning a worker thread
-  on a dead call. Because every call now streams, an alias pointed at a
-  model or org that cannot stream (OpenAI's verified-org streaming
-  entitlement, a gateway api-version predating `stream_options` — e.g.
-  older Azure OpenAI deployments) fails at request time where 1.7's
-  non-streaming single-shot call succeeded; remediation is on the
-  serving side (verify the org, bump the api-version/gateway) — there is
-  deliberately no per-model non-streaming fallback left to configure. These lanes are also complete-or-error now: a stream
-  that ends without any finish signal is treated as a generation that
-  died mid-response and retried, instead of storing the partial text as
-  a clean result (previously a half-generated compaction summary could
-  silently replace real history). Caveats: these lanes now carry the
-  same `stream_options: {include_usage: true}` the chat loop always
-  sent — OpenAI-compatible servers old enough to *ignore* it stop
-  producing usage rows on these lanes, and servers strict enough to
-  *reject* unknown fields (pre-2024 llama.cpp/proxy builds) will 400 —
-  such a server already couldn't serve turnstone's chat loop, but a
-  judge/utility alias pointed at one worked on 1.7 and needs to move to
-  a current server. Transient mid-stream deaths (connection drop, proxy
-  hiccup) are re-issued in place up to twice with exponential backoff —
-  the retry the SDK's request loop used to provide these lanes
-  invisibly. Each lane accepts its own terminal marker (Anthropic
-  `message_stop`, Responses terminal events); a lax server/gateway that
-  never sends any terminal signal needs
-  `{"finish_reason_optional": true}` in the model definition's
-  capabilities JSON, which restores 1.7's tolerance (clean end-of-stream
-  after output = completion) for that model on every lane — without it
-  such streams fail as died-mid-generation, because SSE gives no way to
-  tell the two apart and the default favors catching truncation. The
-  unread `supports_streaming` capability flag (and its admin tile) is
-  gone; the o-series models it described are dropped from the capability
-  table entirely (see Removed).
-
-- **One turn interface for every model call: `core/model_turn.py` (#827).**
-  Judges (intent + output guard), perception, title generation, compaction,
-  web-fetch extraction, the eval harness, the optimizer's meta lanes, and
-  task agents all advance a trajectory through the same plant-call
-  primitive the agent seam pioneered — Turn IR in, one shared lowering
-  (argument sanitize → minted-id restore → vLLM reasoning attach), one
-  shared re-ingest (blank-id repair → native-lane finalize). The judges'
-  hand-built OpenAI-dict path is gone, and with it the Gemini judge's
-  tool-blindness: evidence tools now work on Google models because the
-  native lane round-trips `thought_signature` (with pairwise repair for
-  blank-id compat responses). Provider adapters still take lowered wire
-  dicts — the transport collapse and main-loop migration are tracked as
-  #831 / #832.
-
-- **task_agent keeps its model's reasoning across its own tool loop — on
-  every provider lane.** A task agent's replayed turns now carry the
-  provider-native reasoning lane the model produced — Anthropic thinking
-  blocks with their signatures (commercial or an anthropic-compatible
-  server), OpenAI Responses reasoning items, Gemini `thought_signature`
-  fidelity blocks, and the reasoning text a vLLM `--reasoning-parser` /
-  llama.cpp `reasoning_format` surfaces on the Chat Completions lane —
-  instead of each turn being rebuilt from text + tool calls with the
-  reasoning dropped. On a thinking model this restores reasoning continuity
-  across the agent's own multi-turn tool use. On the wire the agent's
-  session-minted sub-tool ids are mapped back to the provider's own ids
-  (`restore_provider_tool_ids`), so the native block — replayed verbatim,
-  its signature never touched — the `tool_calls` mirror, and each tool
-  result always agree; internally the minted ids still key the live card,
-  recall, and the cancel ledger unchanged. Replay honors the same per-model
-  `replay_reasoning_to_model` flag the main loop uses on every lane: the
-  vLLM Chat-Completions field replay keeps its server-type gate, and
-  llama.cpp stays capture-only, matching main-loop behavior. The native
-  lane is finalized by the same shared builder as the main loop's, so the
-  two harnesses cannot drift.
-
-- **Background shells: `bash` gains `run_in_background`, plus `bash_output` /
-  `kill_shell`.** Setting `run_in_background=true` starts the command as a
-  detached shell and returns immediately with a `bash_N` handle — "start a dev
-  server, use it in a later call" is back as an explicit opt-in (the shape
-  follows the convention the major coding agents converged on). `bash_output`
-  returns only output produced since the previous read (optionally filtered by
-  a regex) plus status and exit code; `kill_shell` terminates the shell's
-  whole process group. Output is buffered per shell with a drop-oldest cap, so
-  a chatty server can't grow memory unbounded. When a background shell exits,
-  a system notice lands at the next seam (waking an idle workstream if
-  needed). Shells survive a generation cancel, die with the workstream, and
-  never outlive a task_agent that started them; anything a background shell
-  itself backgrounds is still reaped when that shell exits — the no-leak
-  guarantee below is unchanged.
-
-### Changed
-
-- **Breaking (1.8): compaction feedback moved from `info` events to the
-  typed `compaction` SSE event.** Pre-1.8 SSE/SDK clients that ignore
-  unknown event types no longer see compaction lines (they are
-  deliberately not dual-emitted — dual emission would double-render on
-  every current client). Consume the `compaction` lifecycle event (see
-  the API reference and the `CompactionEvent` SDK type); embedders
-  driving `ChatSession` through a duck-typed `SessionUI` are unaffected
-  (the classic `on_info` lines are restored for them — see Fixed).
-
-- **Sampling knobs (temperature, reasoning effort) now ride one assignment
-  scheme: per-model alias value → operator-stored global setting → the
-  model definition's declared default (effort only) → field omitted.**
-  Turnstone previously manufactured values onto every unconfigured
-  request — a hidden `temperature: 0.5` and a `reasoning_effort: "medium"`
-  baked in at three layers — overriding serving-side defaults like a vLLM
-  model's `generation_config`. Unconfigured installs now send neither
-  field and the inference engine's own defaults rule; `model.temperature`
-  is blank by default ("inherit each model's own default") and
-  `model.reasoning_effort` defaults to the empty "inherit" choice. The
-  per-model → global resolution lives in one shared resolver used by the
-  session factories, the `/model` switch, and every `model_turn` lane, so
-  the same alias samples identically on every surface. CLI
-  `--temperature` / `--reasoning-effort` likewise default to inherit.
-
-  **Upgrade notes:**
-  - The empty (`""`) reasoning-effort choice changed meaning from
-    "explicitly disable thinking" to "inherit the model/serving default".
-    On local manual-thinking models (e.g. Qwen templates with
-    `enable_thinking`), a stored `""` previously sent
-    `enable_thinking: false`; it now sends nothing, so the template's own
-    default (often thinking ON) applies. Use **`none`** to actually
-    disable reasoning.
-  - Workstreams saved by earlier versions carry the old defaults
-    (`temperature=0.5`, `reasoning_effort=medium`) in their persisted
-    config and keep that exact behavior on resume; they pick up the new
-    inherit semantics the next time you change the model or a sampling
-    knob in that workstream. New workstreams inherit from the start.
-
-### Removed
-
-- **O-series and pre-5.4 GPT-5 rows dropped from the OpenAI capability
-  table.** `o1`, `o1-mini`, `o3`, `o3-mini`, `o3-pro`, `o4-mini`,
-  `gpt-5`, `gpt-5-mini`, `gpt-5-nano`, `gpt-5-pro`, `gpt-5.1`,
-  `gpt-5.1-codex-max`, `gpt-5.2`, `gpt-5.2-pro`, and `gpt-5.3` no longer
-  have built-in capability rows — OpenAI has retired these model ids
-  from the API, so the rows described contracts no request can reach
-  anymore. The table floor is now `gpt-5.4`; the search-api and
-  audio/STT/TTS rows are unchanged. An alias still pinning a retired id
-  fails at OpenAI itself; any other unlisted commercial id resolves to
-  the generic commercial defaults (temperature sent, no declared
-  reasoning-effort vocabulary, 200K window) — declare the contract on
-  the model definition's capabilities JSON if you run one, or move to a
-  current model.
-
-### Fixed
-
-- **A failed worker-thread spawn no longer wedges the workstream — at
-  either spawn site — and never masquerades as success.** If
-  `Thread.start()` itself raised (thread exhaustion, out-of-memory), the
-  dispatcher had already claimed the worker slot but the flag's only
-  clearer lived in the never-started thread — the workstream looked idle
-  forever while every subsequent message queued behind a worker that
-  didn't exist, until an operator force-cancel. The claim is now rolled
-  back under the lock and the error propagates, so the workstream is
-  dispatchable again as soon as resources recover. Affected every
-  dispatch path (sends, wakes, retries, deferred-send drain, init). The
-  same failure at the deferred-send drain's own spawn rolls back the
-  just-accepted entry and answers the retryable `queue_full` (previously
-  a 500 landed *after* the entry was registered — an invisible,
-  unretractable phantom that later dispatched as duplicate turns), and a
-  `/command` whose worker never spawned now answers **503**
-  `{"status": "error"}` instead of the generic 200 ok that told SDK
-  callers their `/clear` or `/resume` had applied.
-
-- **Manual `/compact` from the web UI: no phantom user turn, no frozen
-  server, cancellable.** A slash command typed into the web composer no
-  longer renders as a user chat bubble (it echoes as a distinct command
-  chip — commands aren't conversation turns and were never persisted as
-  such). `/compact` itself now dispatches onto the workstream's worker
-  slot instead of running inline on the server's event loop — previously a
-  long compaction froze every SSE stream on the node for its whole
-  duration, which is also why its own progress only ever arrived as one
-  burst after the fact. The manual path carries `send()`'s full generation
-  discipline (`compact_now()`): a force-abandoned compaction goes stale
-  instead of swapping history under a successor turn — and retires at its
-  next checkpoint instead of running out its remaining summary calls,
-  with its late lifecycle events fenced off (`compaction_id` on every
-  event, `superseded` on end events — both in the SDKs) so they can't
-  animate, tear down, re-title, or falsely narrate a successor's card or
-  activity pill; a cancel aimed at it is consumed on exit (previously it
-  bricked every `/compact` retry until the next message); a Stop click on
-  an idle session can't pre-abort the next compaction; a Stop that lands
-  in the completion tail — after the last cancel check, or during a retry
-  backoff (which now aborts immediately instead of sleeping it out) — is
-  honored rather than silently eaten; and Stop now aborts the in-flight
-  summary HTTP call itself (the compaction lane registers its stream in
-  the same abort seam the main loop uses), so cancelling a compaction is
-  immediate instead of waiting out a model call.
-
-- **Sends during a command window are deferred, ordered, bounded, and
-  honestly rendered — never silently truncated or lost.** Messages sent
-  while any slash command holds the worker slot are **deferred**: answered
-  `{"status": "queued", "msg_id"}` immediately and dispatched as ordinary
-  full-fidelity sends (attachments and sender identity included) when the
-  command finishes — never routed through the mid-turn interjection
-  queue, whose semantics are turn-shaped: previously a send during a
-  manual `/compact` was silently truncated to 2,000 characters, a second
-  participant in a shared workstream was locked out with a misleading
-  "another participant's turn" 409 for the whole compaction, and a
-  message queued across a `/resume`/`/new` could be answered into the
-  post-swap workstream. Because the response is immediate,
-  timeout-bounded callers — the coordinator's `send_message`, the console
-  proxy, SDKs, anything behind a stock reverse proxy — can no longer lose
-  a message to a multi-minute command window; the deferred send is
-  retractable until dispatch via the same `DELETE .../send` used for
-  queued interjections (node-local, in-memory — the API reference
-  documents the at-most-once durability contract). Deferred responses
-  carry `"deferred": true`; the pending list is the **order authority**
-  (a fresh send — or a coordinator dispatch, or a queued-nudge wake —
-  lines up behind acknowledged entries instead of overtaking them, with
-  the two-term barrier defined once on the workstream so the wake gate
-  also honors a claimed entry whose dispatch is mid-flight, and the gate
-  re-arms at the drain's exit even when everything pending was
-  retracted); acceptance is **bounded** (10 pending per workstream — the
-  interjection queue's own backpressure contract; the 11th answers the
-  retryable `queue_full` instead of pinning attachment bytes without
-  limit and then running one unattended turn per entry); a dispatch
-  crash re-queues the entry instead of eating an acknowledged message,
-  and a drain thread that fails to *start* rolls the acceptance back and
-  answers `queue_full` rather than parking a phantom the client can
-  neither see nor retract; each dispatch emits a pane-tier
-  `message_dispatched` event (`folded: true` for interjection fold-ins)
-  so queued-bubble UI keeps its retract affordance exactly until the
-  message truly leaves — including when the send was accepted by a pane
-  that believed the workstream idle, which now renders a real queued
-  chip instead of a sent-looking bubble, releases the composer (a
-  deferred send has no running worker to wait on), and cleans up fully
-  when the send is refused or the chip retracted instead of stranding
-  the pane in Stop mode. Dismissing a queued bubble — interjection or
-  deferred — is a server-confirmed `DELETE`, and retracting a deferred
-  send that carried attachments tells the user they were discarded
-  instead of silently expiring them.
-
-- **Slash commands hold the worker slot with a loud contract.**
-  A `/compact` raced against an in-flight turn is refused with an
-  explicit busy response. Every other slash command runs through the same
-  worker slot too — mutual exclusion against sends, a running compaction,
-  and each other, with a busy answer replacing the old silent interleave —
-  while the endpoint still awaits quick commands' completion off-loop
-  (without parking an executor thread per request); the post-command pane
-  refreshes (`clear_ui` after `/clear`/`/new`/`/resume`, the
-  workstream-name sync) ride the worker itself, so a command that
-  outlives the endpoint's 25s response backstop still refreshes every
-  pane on completion (the backstop sits under the console proxy's 30s
-  client timeout so the degraded `running` answer can actually traverse
-  a proxied pane, which now surfaces it instead of silence; the
-  `/command` response contract — `ok` / `running`, with busy refusals
-  answering a loud HTTP 409 rather than a silent 200 — is now documented
-  in the API reference and the OpenAPI spec).
-
-- **Compaction status stays truthful across every UI surface.** Manual
-  compaction
-  success also refreshes the status line/context pill immediately (parity
-  with auto-compaction), compaction failures keep feeding the typed
-  `error` event and the node error counter (while a CLI Ctrl-C reports as
-  cancelled, not a failure), one Stop prints one notice (a cancelled
-  auto-compaction no longer stacks "Compaction cancelled." on top of
-  send's own "[Generation cancelled]"), the workstream activity pill
-  shows "Compacting context…" for the whole summarize phase, restores
-  cleanly afterwards, and can no longer be stranded by a force-stopped
-  compaction (a new turn's generation claim breaks a stale latch). Every
-  retry backoff on the session (stream retries, task agents, notify
-  delivery, compaction) now aborts immediately on Stop via one shared
-  cancel-aware helper instead of sleeping out its exponential delay.
-
-- **Compaction failures report exactly once, to the right owner.** A
-  compaction failure reports
-  exactly once (auto-compaction errors defer to the turn's fatal handler
-  instead of doubling the red row and the error metric), failed-end
-  notice suppression is computed once by the emitter (a `notice` bool on
-  the end event — in the SDKs — replaces hand-synced client policy), and
-  a manual `/compact` failure no longer crashes the CLI REPL. `/compact`
-  on a workstream showing the `error` badge restores the badge on exit
-  instead of stamping `idle` over it (the compaction neither retried nor
-  resolved the failed turn). A force-cancelled initial send that
-  completes late still delivers its scheduled-run completion
-  notification (the only completion signal unattended workstreams have);
-  the other post-command pane refreshes and error notices remain
-  owner-guarded, so a force-cancelled wedged command that unwedges late
-  can't wipe panes or inject stray notices into a successor turn.
-
-- **Pre-1.8 embedder UIs keep their compaction lines.** Embedders
-  driving `ChatSession` with a pre-1.8 duck-typed `SessionUI`
-  (no `on_compaction` hook) get the classic `on_info` compaction lines
-  back — threshold notice, `part k/N`, retry waits, token delta +
-  summary box — instead of silent history swaps. (See the breaking
-  event-contract note under **Changed** for SSE/SDK clients.)
-
-- **Static MCP servers: a pushed catalog change no longer wedges the shared
-  session (#839).** The static-path `*/list_changed` handler awaited its
-  catalog refresh inline in the SDK's receive loop, but the refresh's own
-  request can only be answered by that (now parked) loop — the refresh never
-  completed, and every user's in-flight calls on the shared per-node session
-  stalled behind it, unbounded, until the health loop's ping timeout tore the
-  transport down (which was also the only way the changed catalog ever
-  landed). Push refreshes now run as spawned tasks — debounced, coalesced per
-  (server, kind), bounded by the connect timeout, and serialized on the
-  per-server connect lock — and the manual and post-reconnect refreshes
-  publish under that same lock, so a slower publisher can no longer land a
-  staler catalog over a fresher one. Every teardown path now also clears the
-  notification debounce stamp, so a reconnected server's first push refreshes
-  immediately. Push-refresh debouncing is now per (server, kind) on BOTH the
-  static and per-user pool paths — a tools push no longer swallows a prompts
-  push arriving in the same 5-second window. A change genuinely lost to the
-  debounce window (a same-kind push landing after the prior refresh finished,
-  which the server will never re-announce) is recovered by an automatic
-  health-tick retry rather than staying invisible until an unrelated push or
-  a reconnect. The resource-refresh fan-out on both paths no longer orphans
-  its sibling list call when one of the pair fails fast — the real error
-  surfaces immediately (not masked as a 30-second timeout) and the surviving
-  sibling is cancelled and reaped, under a bounded grace, inside the scope. A
-  push refresh that fails while the connection stays up is likewise retried on
-  the next health-loop tick until one completes — previously a single
-  transient blip left the shared catalog stale for every user on the node
-  until an operator intervened. An operator `/mcp refresh` no longer parks
-  behind a busy per-server connect lock (a slow reconnect attempt could eat
-  the whole 30-second refresh budget and fail the pass for every healthy
-  server behind it) — the busy server is skipped on both the connected and
-  disconnected branches, reported distinctly as "skipped" rather than as a
-  false "no changes", the skip arms the automatic retry, and a
-  force-reconnect drops the session up front so queued push refreshes can't
-  starve it. Static-path resource and prompt catalogs are now size-capped
-  like the pool path's (and like static tools) at discovery and on every
-  refresh, so a misbehaving server's push can't balloon the node's merged
-  catalogs. Deleting or reconfiguring a server can no longer leave it
-  half-removed: the config removal and all cleanup are serialized under the
-  connect lock (a cancelled removal completes its cleanup rather than
-  stranding a live session and published catalog with the config already
-  gone), and `reconcile_sync` retries a removal that timed out instead of
-  marking it done — previously a DB-driven delete of a busy server could be a
-  silent, permanent no-op until process restart. A refresh outcome now
-  threads consistently to every operator surface off one source of truth
-  (the per-server `last_refresh_outcome`): a busy-skip and a genuine failure
-  are each reported distinctly from a real "no changes" — `/mcp refresh`
-  prints "skipped" or "failed" rather than a false "no changes", and the
-  node-internal refresh endpoint returns `202 skipped` instead of a
-  misleading `200 ok` for a refresh that never ran. A single-kind push
-  refresh no longer paints the whole server healthy: because the
-  error/outcome state is server-scoped, a successful tools push while the
-  prompts catalog is still broken (or vice versa) no longer clears the
-  failure — only a full refresh pass declares "ok".
-
-- **OpenAI Responses streaming: truncated and refused responses no longer
-  vanish.** A response that hit `max_output_tokens` terminates the stream
-  with `response.incomplete`, which the stream consumer did not handle —
-  the turn was mislabeled `finish_reason: stop` and its final usage and
-  collected output items were dropped. Refusal parts had no streaming
-  handler at all, so a refusal rendered as empty content instead of the
-  `[Refused: …]` text the non-streaming path produced. Both now match:
-  truncation maps to `length` with usage/items intact, refusals render
-  in content. Applies to the chat loop and every drained single-shot
-  lane (#831).
-
-- **task_agent: sub-tool ids no longer alias across a local model's reused
-  ids.** A local model that reissues per-response sequential tool-call ids
-  (`call_0` every turn) made two of a task agent's steps share one id — the
-  live card collapsed both onto one DOM row while `/history` recall kept them
-  apart, so the two views disagreed. Sub-tool ids are now minted
-  `{parent}::r{run}s{step}::{id}`, unique within the session (across an
-  agent's turns and across concurrent or sequential runs), and that one id
-  keys the nesting registry, the live rows, recall, and the cancel ledger.
-  On the wire the agent's self-built history carries the provider's own ids,
-  restored from the mint map (see the reasoning-lane entry under Added), and
-  malformed tool-call arguments are legalized the same way the main loop's
-  wire prep does.
-
-- **bash tool: never hang on a backgrounded child.** A command that left a
-  long-lived process running (`server &`, a daemon) could wedge the whole
-  workstream forever — the tool read stdout/stderr to EOF, which never arrived
-  because the child inherited the pipe, and the timeout watchdog bailed once the
-  foreground `bash` had exited. The tool now waits on the tracked process
-  (bounded by the tool timeout) and terminates its whole process group on
-  return, so the call always completes. Undecodable output is preserved
-  (`errors="replace"`) instead of being dropped as a spurious error.
-  - **Behavior change:** a process the command backgrounds no longer survives
-    the call — nothing persists across bash invocations. (First-class
-    "run this in the background" support landed separately — see
-    `run_in_background` under Added.)
-
-## [1.7.3]
-
-A small feature and maintenance patch for the 1.7 line. No schema migrations
-and no new configuration knobs.
-
-### Added
-
-- **OpenAI GPT-5.6 (Sol/Terra/Luna) support** — the Responses provider
-  understands the GPT-5.6 family: the `reasoning.mode` control, the new
-  `max` effort tier, and `text.verbosity`, with golden wire payloads pinning
-  the request shapes. The `openai` dependency floor moves to `>=2.44`.
-
-### Changed
-
-- **Engineer base prompt hardened with process discipline** — the default
-  base prompt for non-coordinator sessions now works in phases scaled to the
-  size of the change, defaults to red-green for testable work, scopes to the
-  smallest sufficient diff, stops to report after repeated failed attempts
-  instead of thrashing, reports only observed results, and delegates
-  exploration to `task_agent`. Persona prompts freeze into the workstream
-  stamp at creation, so this reaches new workstreams only.
-
-### Fixed
-
-- **Unknown reasoning-mode warnings name the allowed modes** — a model
-  definition with an unrecognized reasoning mode now logs the valid options
-  instead of leaving the operator to guess.
-
-### Documentation
-
-- **HYPOTHESIS.md / PRIMER.md** — the control normal form is tightened and
-  the factored Q_E reading is carried into the glossary; the plain-language
-  PRIMER stays in sync.
-
-## [1.7.2]
-
-A feature-bearing patch for the 1.7 line. Rather than hold this work for the
-larger 1.8 churn, the fixes and the smaller features that had already
-stabilised on `main` are rolled into the stable line now: a rich preview
-pane, persona/project settings on scheduled tasks, and a batch of streaming,
-rendering, and nudge-delivery hardening.
-
-> **⚠️ Before upgrading:** 1.7.2 adds Alembic migration `066`, applied
-> automatically on first start. It adds two `Text NOT NULL DEFAULT ''`
-> columns (`persona`, `project_id`) to the `scheduled_tasks` table; existing
-> rows migrate to the empty default, which is byte-identical to pre-066
-> dispatch behaviour. The change is additive and reversible, but — as always
-> — back up your storage before upgrading (`pg_dump` for PostgreSQL; copy the
-> database file for SQLite).
-
-### Added
-
-- **Rich preview pane + `open_preview` tool** — a workstream can now open a
-  rendered preview (HTML, Markdown, and other kinds) in a pane beside the
-  conversation via the new `open_preview` tool. Guarded fetches stream under
-  a byte budget whose ceiling tracks the widest per-kind cap, preview blob
-  ids are salted, and a preflight probe handles legacy charsets and a
-  remote-assets opt-in. See `docs/tools.md`.
-- **`allow_private_network` opt-in for `web_fetch` / `open_preview`** —
-  private-address fetch and preview targets stay blocked by default; an
-  operator can opt a workstream in through the settings registry when a
-  private endpoint is genuinely intended. (Distinct from the 1.7.1 `[oidc]`
-  flag of the same name, which governs identity-provider discovery.)
-- **Persona + project settings on scheduled tasks** (migration `066`) — a
-  scheduled task can now pin the **persona** and **project** of the
-  workstream it dispatches, matching the levers a manually-created workstream
-  already carries. Both default to empty (kind-default persona / no project),
-  so existing schedules dispatch exactly as before.
-
-### Fixed
-
-- **Streaming fast-path overflow recovery** — fast-stream tokens are now
-  batched and overflowed SSE listeners recover instead of stalling (and
-  `connectSSE` no longer opens into a hidden background tab). The same
-  overflow-recovery companions were carried to the coordinator pane, so a
-  coordinator watching many children recovers dropped listeners the same way
-  the live-session view does.
-- **Renderer containment** — markdown sentinel-forgery and recursive-frame
-  content loss are contained, and an indented fence close no longer drags its
-  indent into the enclosed code content.
-- **Idle nudge / wake delivery** — nudge and wake delivery is hardened across
-  session eviction, cancellation, and identity rebinds; the wake gate now
-  requires a real nudge queue, refused wakes are logged, and
-  `initial_message_status` is typed as a closed enum on the wire.
-- **`web_fetch` extraction inherits model settings** — the completion that
-  extracts content from a fetched page now inherits the workstream's model
-  settings instead of falling back to defaults.
-- **UI panes** — ephemeral panes close on split-dismiss instead of orphaning
-  a tab, and an unsplit skips the redundant refresh after an ephemeral pane
-  closes.
-- **Shared code-highlight CSS** — renderer-output CSS is shared so the console
-  and coordinator panes highlight code identically.
-
-### Security
-
-- **`Content-Disposition` filenames made wire-safe** — download filenames
-  derived from user-controlled text are sanitised (latin-1- and
-  control-char-safe, quoting-safe) before they reach the `Content-Disposition`
-  response header, including the fallback path.
-
-### Documentation
-
-- **HYPOTHESIS.md: daemons + the outer loop, plus a plain-language PRIMER** —
-  the harness north-star document gains its daemon / outer-loop treatment and
-  a new top-level `PRIMER.md`.
-
-## [1.7.1]
-
-A maintenance and hardening patch for the 1.7 line. No schema migrations;
-the credential-redaction work below is additive and needs no configuration
-change. The one new operator-facing knob is the opt-in `[oidc]
-allow_private_network` flag (default off).
-
-### Security
-
-- **Credential redaction hardened across the tool-call surface** — the
-  redactor that scrubs secrets from tool arguments and log previews was
-  reworked on both the backend and the browser to close several leak paths
-  and to fix false-positive and performance issues. Malformed tool-call
-  arguments are now legalised before they reach the wire; the tool-args log
-  preview scrubs credentials and control characters; and the coordinator's
-  tool-call cards gain a matching client-side redaction pass so the JS and
-  backend redactors stay at parity. Pattern coverage now includes
-  `secret_access_key` / `aws_secret_access_key` multi-segment keys, bare
-  `token=` / `key=` forms (guarded by a negative lookbehind to avoid
-  false positives), and SQLAlchemy `+driver`-qualified connection-string
-  schemes matched case-insensitively.
-- **OIDC SSRF guard: `[oidc] allow_private_network` opt-in** — self-hosted
-  identity providers on private networks can now be reached by setting
-  `allow_private_network = true` under `[oidc]` (default off; the MCP OAuth
-  path stays strict). Rejections of discovered endpoints carry the opt-in
-  hint so the misconfiguration is self-explanatory. See `docs/oidc.md`.
-
-### Added
-
-- **Persona discoverability + forgiving name resolution** — personas are
-  now discoverable by agents, and persona-name resolution tolerates
-  case/whitespace variation; a not-found resolution reports the offending
-  input verbatim instead of a bare error.
-
-### Fixed
-
-- **MCP transport lifecycles routed through per-entry owner tasks**
-  (#787/#788) — static and pooled MCP transport lifecycles are now driven
-  by per-server / per-entry owner tasks, with a hardened disarm-sweep loop
-  guard and targeted exception handling in place of a broad `BaseException`
-  arm, so a dying transport can no longer spin the CPU or strand delivery.
-- **Client-construction failures surface as misconfiguration, not raw
-  500s** — a model whose client cannot be constructed now reports a factory
-  misconfiguration, and the raw exception text is kept out of the resulting
-  503 response.
-- **Postgres history search survives oversized rows** — a conversation row
-  exceeding Postgres' full-text limits no longer aborts history search.
-- **Agent-tool render is idempotent** — tool rendering no longer deep-copies
-  a tool definition until a description actually changes, so no-persona
-  sessions share the tool constant (correctness plus a hot-path allocation
-  win).
-- **Private-project workstream visibility scoped to members** — workstreams
-  in a private project are visible to project members only, not to every
-  admin; coordinator tenancy checks now use request-scoped storage.
-- **Pane hotkeys work off macOS and match across surfaces** — the pane
-  keyboard shortcuts no longer collide with browser accelerators on
-  non-macOS platforms and behave consistently across surfaces.
-
-## [1.7.0]
-
-The headline of the 1.7 line is **Personas** — operator-authored control
-over how each workstream composes its system message and capability
-envelope. The rest of the release hardens the pieces a persona leans on:
-concurrent approvals, cross-provider reasoning-effort control, cooperative
-compaction, multi-user session safety, and MCP resilience for unattended
-work.
-
-> **⚠️ Before upgrading:** 1.7.0 adds Alembic migrations `062`–`065`,
-> applied automatically on first start (projects, personas, and two
-> smaller schema tidy-ups). Migration `063` creates the `personas` table
-> with its six seed personas and converts existing `creative_mode`
-> workstreams to the `writer` persona in place. The changes are additive
-> to your conversation data, but — as always — back up your storage before
-> upgrading (`pg_dump` for PostgreSQL; copy the database file for SQLite).
-
-**Breaking changes at a glance** (details in the sections below): the
-`/creative` REPL toggle removed (replaced by the `writer` persona), the
-`turnstone-bootstrap` entry point renamed to `turnstone-doctor`, and the
-approval-status API/SDK field `pending_approval_details` changed from a
-single object to a list (one entry per concurrent approval cycle).
-
-### Added
-
-- **Personas** (#683) — a named, reusable bundle attached to a workstream
-  at creation, controlling system-message composition and the capability
-  envelope via exactly four levers: base-prompt override, tool visibility
-  set, MCP on/off, and memory on/off. The persona is resolved once and
-  snapshotted into `workstream_config`; editing or archiving a persona
-  never changes an existing workstream. Six seed personas ship with
-  migration `063` (`engineer` and `orchestrator` are the per-kind
-  defaults with no overrides, so zero-touch behavior is unchanged;
-  `scribe`, `researcher`, `writer`, and `executive` are curated
-  envelopes). Selectable on every creation surface (web pickers, the
-  create API/SDKs, coordinator `spawn_workstream` / `spawn_batch`, and
-  `turnstone --persona <name>`); authored in the console's new
-  Governance → Personas tab (`persona.{create,read,write}` perms,
-  archive-only lifecycle). See `docs/personas.md`.
-- **Projects — governed resource containers** (#724) — group workstreams
-  and their resources under a project (migration `062`), with
-  project-scoped memory, a per-project resources view, a project column on
-  the saved list, and server-enforced private-project workstream
-  visibility.
-- **Task-agent sub-harness** (#732) — a spawned task agent now runs on its
-  own Turn-IR sub-harness with parent-tagged step events: its sub-tool
-  steps nest inside an expandable card in the parent trajectory, its
-  sub-trajectory is recallable, and each agent gets read isolation from
-  its siblings.
-- **MCP static-server autonomous reconnect** (#768) — statically
-  configured MCP servers are now kept live by a health loop
-  (capped-jittered backoff, ping-based liveness) instead of silently
-  staying dead after the first transport drop.
-- **Attachments — capability-gated client-side fallback** — when the
-  active model can't natively handle an attachment, the client degrades
-  gracefully (PDF → extracted text, audio → transcript) instead of
-  failing the turn.
-- **Eval measurement / optimizer split** (#763, #765) — `turnstone-eval`
-  is now a measure-only substrate with the prompt optimizer factored out,
-  plus a new skill-adherence measurement mode.
-- **Deployment examples** — a vLLM + LiteLLM unified-memory inference
-  example showing a 3-model co-resident stack with an HF loader (#686,
-  #688), and an Altair + `vl-convert-python` visualization stack (#685).
-- **Concurrent approvals and a long-session frontend overhaul** (#754,
-  #755, #773, #775) — the live-session frontend was reworked for long
-  runs (the pipeline is wedge-proofed and its hot paths de-O(N)'d), and on
-  top of it a workstream can now hold more than one tool call awaiting
-  approval at a time. Each parallel batch gets its own approval cycle,
-  with one card per pending call in the interactive and coordinator UIs,
-  cycle-keyed tracking in Slack and Discord, and cycle-routed resolution
-  across the server/console/SDK APIs; sub-agent tool gates run the
-  intent-judge pipeline as their own generation. The send button no longer
-  sticks disabled after a batch resolves — orphaned approval cycles are
-  pruned and the app is the sole owner of the button state.
-  *(BREAKING: the `pending_approval_details` field is now a list, oldest
-  first.)*
-- **Reasoning-effort control on every provider lane** (#771, #774) — the
-  session effort knob now reaches local backends too: it drives
-  `chat_template_kwargs` on the anthropic-compatible and openai-compatible
-  lanes and threads through to Gemini and xAI, alongside the commercial
-  providers that handle effort natively. The console surfaces each model's
-  effective effort ladder in plain words and adds an always-on
-  thinking-mode option to the model form. Effort snapping is ordinal —
-  it rounds up and caps at the model's ceiling rather than silently
-  dropping.
-
-### Changed
-
-- **Skills are capability-context, not identity** (#762) — a task agent's
-  identity now comes from its persona; an applied skill's body is demoted
-  to capability context and moved out of the identity system message.
-  Skill-body substitution is unified across every invocation context so
-  the same skill renders identically whether loaded interactively, by the
-  model, or inside a sub-agent.
-- **`turnstone-doctor` replaces `turnstone-bootstrap`** (#718)
-  *(BREAKING)* — the setup/diagnostics entry point is renamed; update any
-  scripts or service units that invoke `turnstone-bootstrap`.
-- **Honest cancellation dispositions** — cancelled or timed-out
-  side-effecting tools now report an `UNKNOWN` disposition rather than a
-  flat failure, tool dispositions are typed (not just prose), and a
-  coordinator cancel propagates down the sub-tree.
-- **Multi-user shared-workstream context** (#750) — in a shared
-  workstream, send is gated to the acting participant while a turn is in
-  flight (both the interactive and coordinator surfaces), cross-user
-  mid-turn interjections are blocked, and shared-workstream state plus
-  fork sender attribution are now durable.
-- **Cooperative compaction** (#730) — the context budget is anchored to
-  the provider's true capacity, the summary call is chunked so it can't
-  overflow, and the active plan and the outstanding ask are carried across
-  compaction verbatim. The `recall` tool is scoped to the compacted-away
-  past.
-- **Intent judge sees the full tool arguments** (#760) — the judge's
-  argument projection is no longer narrowed, so it stops issuing confident
-  false denials on a partial view. The output-guard judge sources its real
-  context window, and `context_window = 0` in `config.toml` now means
-  auto-detect.
-
-### Fixed
-
-- **Compaction resume hardening** (#731) — checkpoint markers are
-  persisted so resume rehydration is bounded, context-overflow on resume
-  is recovered across providers, and a recognized rate-limit is no longer
-  misclassified as context overflow.
-- **MCP unattended-work resilience** (#706, #742, #767) — dead-transport
-  handling is completed, consented OAuth (OBO) tokens are refreshed
-  proactively so autonomous runs don't strand on an expired grant, the
-  Entra ID on-behalf-of impersonation flow blockers are closed (migration
-  `065` adds the OIDC `oid`), and OAuth refresh failures are classified so
-  a transient blip never revokes consent nor a dead grant strands the
-  user.
-- **Memory writes** (#735) — save/update is a single atomic upsert, and
-  writing a memory no longer recomposes the system prefix mid-session.
-
-### Removed
-
-- **`/creative` removed** *(BREAKING)* — subsumed by the Personas feature
-  above: the REPL toggle (and its tab completion) is gone, and the
-  `writer` seed persona replaces it — start a session with
-  `turnstone --persona writer` or pick *Writer* in the web
-  pickers. Unlike the old fork, the writer persona composes the full
-  system message, so session context and mandatory prompt policies now
-  apply to prose-only sessions too. The `creative_mode` key in
-  `workstream_config` is no longer read or written. Migration `063`
-  converts existing creative-mode workstreams to the `writer` persona
-  automatically, so they resume as writing sessions rather than as
-  legacy defaults.
-
-### Security
-
-- **High-risk skill activation is gated** (#762) — a model-initiated load
-  of a `high`- or `critical`-risk skill is gated and fails closed when the
-  backing storage is unavailable, so an untrusted turn can't silently
-  pull in a dangerous capability.
-- **Dependency security floors** — `cryptography` and `starlette` are
-  pinned to security-fixed minimums.
-- **CI publish hardening** — the vendored-JS dispatch path refuses fork
-  PRs, and `workflow_run` publishing is gated to same-repo tag pushes, so
-  a fork can't trigger a release build.
-

-# 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.

-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

 ```
 
-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
+
+- **Single-node production** — `docker compose up` against the bundled
+  `turnstone/deploy/compose.yaml`: 1 server + console + channel + PostgreSQL,
+  pulled from ghcr.io. Good for most deployments.
+- **Local multi-node cluster** — clone the repo and run `docker compose up` at
+  the root for a 10-node fleet + console + Caddy + channel, built locally.
+
+See [docs/docker.md](docs/docker.md) for both.

+- **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.

-client that force-stopped one compaction can use it to ignore stragglers
-from the abandoned run). End events also carry `superseded`: `true` marks
-a force-abandoned compaction retiring after a successor generation took
-over (an OK end's result card still stands: the history swap happened).
-Superseded start/progress events are never emitted.
-Exactly one `start` and one `end` are emitted per attempt,

-synchronous:
-
-- **Quick commands** (everything except `/compact`): the endpoint waits for
-  completion, so `{"status": "ok"}` means the command ran. A command still
-  running after 25 s answers `{"status": "running"}` — the worker keeps
-  going, its output reaches the pane via SSE, and the post-command pane
-  refreshes below still fire when it completes. (The bound sits under
-  common 30 s client/proxy timeouts — the console proxy's included — so
-  the degraded answer actually reaches bounded callers.)
-- **`/compact`**: dispatched fire-and-forget — `{"status": "ok"}` means the
-  compaction *started*. A large context can legitimately compact for many
-  minutes; progress streams as `compaction` SSE events (see the event
-  reference) and the persisted marker row lands on completion. Do not read
-  `/history` expecting the compacted transcript immediately after the
-  response.
-- **Busy refusal**: if a turn or another command holds the worker slot, the
-  command is refused with HTTP **409** `{"status": "busy", "error": ...}` and
-  did **not** run. Retry after the current turn finishes. (The old inline
-  endpoint executed commands unconditionally mid-turn; the 409 makes the
-  refusal loud for callers that only check the HTTP status.)
-
-While a command holds the slot — and afterwards, while earlier deferred
-sends are still waiting (the pending list is the order authority: a fresh
-send never overtakes a message already acknowledged) — `POST .../send`
-requests are **deferred**: the server answers `{"status": "queued",
-"deferred": true, "msg_id": ...}` immediately and dispatches the message
-as an ordinary full-fidelity send (attachments and sender identity
-included) in arrival order once the slot frees — it is never routed
-through the mid-turn interjection queue (no length cap, no cross-user
-rejection). The response arrives within normal round-trip time, so
-timeout-bounded clients (SDKs, proxies, the coordinator) need no special
-handling. To retract a deferred send before it dispatches, issue the same
-`DELETE .../send` with its `msg_id` used for queued interjections —
-`{"status": "removed"}` confirms it will not dispatch; `"not_found"` means
-it already dispatched (or is dispatching). Retracting a deferred send
-discards any attachments it carried; re-attach to send them again. When a
-deferred send dispatches, panes receive a `message_dispatched` event
-(`msg_id`, plus `folded: true` when it folded into a live turn's
-interjection queue rather than spawning its own turn) so queued-message
-UI can settle the right way.
-
-Durability: deferred sends are **node-local and in-memory** (the same
-lifetime as the interjection queue). `"queued"` is at-most-once intake, not
-durable acceptance — if the workstream is closed or the node restarts before
-the window ends, the message is dropped. Anything that must survive a
-restart should be re-sent after confirming dispatch (the turn appears on the

-
-* **Session effort knob (dynamic).** Set the model's thinking mode to
-  "Effort-knob controlled" in the admin Models form (or
-  `thinking_mode = "manual"` + `thinking_param` under
-  `[models.*.capabilities]`) and the provider maps the session's
-  reasoning-effort knob onto the template toggle per-request: effort
-  `none` sends `{<thinking_param>: false}`, any other level sends
-  `true` — the same contract as the real lane's manual mode. ("Always
-  on" / `thinking_mode = "adaptive"` instead always sends `true`: the
-  model self-regulates, so the knob never force-disables — mirroring
-  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

-Two caveats before overriding:
-
-- **SQLite fallback**: when a node runs without PostgreSQL, its fallback
-  database `.turnstone.db` is created in the process working directory.
-  Changing `working_dir` on an existing SQLite-fallback deployment makes
-  the node create a fresh database inside the mount and your prior state

-  The stock compose stacks use PostgreSQL and are unaffected.

-Evaluation for turnstone is split into two commands:
+`turnstone-eval` is the evaluation and prompt optimization system for turnstone. It
+runs test cases against the LLM, scores tool call sequences against expected
+actions, and optionally uses a multi-agent pipeline to optimize the developer
+prompt and tool descriptions.

-- **`turnstone-optimizer`** — the prompt/tool optimizer. Loops over the measurement
-  substrate, using a multi-agent pipeline (analyst, optimizer, observer, diversifier,
-  tool optimizer) to edit the developer prompt and tool descriptions so more tests pass.

-
-Where `oauth_user` makes each user complete a **separate** browser consent per MCP server, `oauth_obo` reuses the user's Turnstone **org sign-in** (OIDC). Turnstone captures one refresh credential per user at login and, on each tool call, mints a short-lived access token scoped to that server's audience. There is no per-server connect step, and one credential covers every `oauth_obo` server. This is the right shape when your identity provider already governs who may reach each backend (an Entra tenant with Entra-protected MCP servers; a Keycloak realm with token exchange).
-
-Access is governed **downstream** by the IdP: a user can only mint a token for a server their delegated permissions allow. Removing that grant at the IdP cuts the user off regardless of their Turnstone state.
-
-### Deployment configuration (`[oidc]` in `config.toml`)
-
-`oauth_obo` requires OIDC SSO to be configured (it is the credential source), plus:
-
-```toml
-[oidc]
-# ... your existing issuer / client_id / client_secret ...
-capture_user_credential = true          # persist the IdP refresh token at login
-obo_grant_profile = "entra"             # "entra" | "rfc8693" — how tokens are minted
-```
-
-- **`capture_user_credential`** (default `false`): when enabled, Turnstone appends `offline_access` to the login scopes and stores the returned refresh token, encrypted with the same `[security] mcp_token_encryption_key` as `oauth_user` tokens. **The encryption key is required** — Turnstone refuses to start with an `oauth_obo` row (or capture enabled) and no key.
-- **`obo_grant_profile`** picks the mint mechanism (the IdP determines which one is valid; this is deployment-wide, not per-server):
-  - **`entra`** — redeems the user's refresh token directly for a token scoped to `<audience>/.default`. `oauth_scopes` on the server row is **not used** (the admin form rejects it under this profile).
-  - **`rfc8693`** — a refresh grant for a subject token, then an RFC 8693 token exchange for the server audience. Per-server `oauth_scopes` **are** sent on the exchange (some IdPs require the audience scope explicitly).
-
-### Adding an `oauth_obo` server
-
-In the admin MCP form, choose **Sign-in passthrough** and set **Audience** (required — the downstream resource the token is minted for, e.g. `api://<app-id>` on Entra or the client id on Keycloak). The client-id / secret / registration fields do not apply and are hidden.
-
-`oauth_obo` servers are accepted only when **OIDC sign-in is configured and enabled** and `[oidc] obo_grant_profile` is a valid profile — the write is rejected otherwise, since a row that can never mint would surface to users as a permanent "please retry" that never heals.
-
-### Identity-provider setup
-
-**Entra (`obo_grant_profile = "entra"`):**
-1. Turnstone's app registration must hold **delegated permissions** to each MCP server's exposed API, with **admin consent granted** (or the MCP app listed in Turnstone's `preAuthorizedApplications`).
-2. Set the server row's Audience to the MCP app's Application ID URI (`api://<guid>`).
-3. **Gotcha (verified):** admin-consent issued *immediately* after creating the app/service principal can silently skip a not-yet-propagated resource — the only symptom is `AADSTS65001` at mint time. Verify the delegated grant landed (`az ad app permission list-grants` / the portal's *API permissions* blade shows *Granted*), or grant it explicitly per resource. A missing grant surfaces in Turnstone as a re-login prompt on the affected server (same rail as a revoked credential), and the `mcp_server.oauth.obo_mint_rejected` log line carries the raw `AADSTS…` text.
-
-**Keycloak / RFC 8693 (`obo_grant_profile = "rfc8693"`):**
-1. Enable **standard token exchange** on Turnstone's client.
-2. Grant the audience: add an audience client scope for each MCP client and attach it to Turnstone's client (optional scopes must be requested — set the server row's Scopes to that scope, or the exchange returns *"Requested audience not available"*).
-3. Set the server row's Audience to the downstream client id.
-
-### Revocation & custody
-
-The captured credential is a single per-user secret that can mint for every `oauth_obo` server, so treat it like any long-lived credential:
-
-- **Cut off one user:** unlink their OIDC identity in the admin console (**Users → OIDC identities → delete**). This revokes the captured credential **and** purges their minted cache rows, so future mints fail and cached tokens are dropped. (Warmed in-memory sessions on server nodes self-expire at the access-token TTL; there is no cross-node per-user session-kill.) Removing the user's access at the IdP is the authoritative cut-off.
-- **Flush a server's minted tokens** (e.g. after narrowing its audience): the server row's **flush cache** action drops all users' cached tokens for that server. This is **not** a revocation — users re-mint on next use from their still-valid sign-in. It is surfaced honestly (audit `mcp_server.oauth.obo_cache_flushed`, response `effect: cache_flush_remints`) so it is never mistaken for cutting access.
-- Per-server revocation in the `oauth_user` sense does not exist for `oauth_obo` — the credential is issuer-scoped and IdP-governed. Revoke at the IdP.
-
-> **Interim for Entra without OBO:** if you don't want host-side minting, admin consent + `preAuthorizedApplications` on each MCP app registration removes the second consent prompt for the plain `oauth_user` flow too (a tenant-config change, no Turnstone code). Tracked in issue #682. It does not remove the per-server connect clicks or per-(user, server) token custody — that is what `oauth_obo` is for.

-# 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.

-# OBO e2e harnesses — single-credential MCP token minting (`auth_type=oauth_obo`)
-
-Manual test harnesses for the `oauth_obo` feature (issue #551). They exercise
-the **real** Turnstone mint path (`get_obo_access_token_classified` →
-`_obo_mint_entra` / `_obo_mint_rfc8693`) against a real identity provider — not
-mocks, not the unit suite. Two grant legs:
-
-- **Entra** (`entra_e2e.py`) — real tenant, one interactive sign-in.
-- **Keycloak / RFC 8693** (`keycloak_e2e.py` + `.sh`) — ephemeral docker, fully
-  headless.
-
-There is also `entra_spike.py` (raw-OAuth **wire** probe, pre-implementation
-reference) and `entra_setup.sh` (creates the Entra app registrations + writes a
-populated `.env`).
-
-**Secrets:** these read config from env. Real credentials live in a **gitignored
-`.env`** (copy `.env.example`); nothing tenant-specific is committed. The only
-literal secret in the tree is the ephemeral Keycloak container's throwaway
-`spike-secret`, which lives and dies with the container.
-
-Not part of CI — run by hand when validating the feature against a live IdP.
-
-## `entra_e2e.py` — end-to-end product exercise (post-implementation)
-
-`entra_spike.py` verified the raw OAuth WIRE (before code existed). `entra_e2e.py`
-verifies the SHIPPED Turnstone code: it does a real Entra login, feeds the
-credential through the real `MCPTokenStore.upsert_oidc_credential` (the call the
-OIDC callback makes on capture), then drives the real
-`get_obo_access_token_classified` → `_obo_mint_entra` against the live Entra token
-endpoint. Checks E1–E7: real mint + aud claim, cache-hit (0 Entra calls),
-single-credential→audiences A&B, rotation write-back, force_refresh re-mint,
-unconsented-audience classification with the credential surviving, and
-flush→re-mint. Reuses the same `.env` and interactive login (SPIKE_CALLBACK_FILE
-for remote browser).
-
-```bash
-source scripts/obo-e2e/.env
-uv run python scripts/obo-e2e/entra_e2e.py
-# one interactive sign-in; E1–E7 then run against the real product code. Results below.
-```
-
-Results — RUN 2026-07-12 on the real tenant, ALL VERIFIED (exit 0): capture
-persisted; E1 mint A (aud=A app-id, cache row refresh_token_ct NULL); E2 cache
-hit (0 extra Entra calls); E3 mint B from the SAME credential (aud=B app-id); E4
-rotation write-back (RT rotated 2040→2091 chars, newest persisted); E5
-force_refresh re-mint (1 Entra call); E6 unconsented C → refresh_failed and the
-credential SURVIVES; E7 flush→re-mint. The real `get_obo_access_token_classified`
-→ `_obo_mint_entra` path against the live Entra token endpoint.
-
-## `keycloak_e2e.py` + `keycloak_e2e.sh` — OSS path (RFC 8693), headless
-
-The rfc8693 equivalent of `entra_e2e.py`: `keycloak_e2e.sh` spins up ephemeral
-Keycloak, configures the realm (turnstone client with standard token exchange,
-mcp-a/b/c clients, aud-mcp-a/b audience scopes, a test user), runs the harness
-against the real `get_obo_access_token_classified` → `_obo_mint_rfc8693`
-(refresh grant → token exchange), then tears down. No browser (password grant).
-
-```bash
-./scripts/obo-e2e/keycloak_e2e.sh
-```
-
-Results — RUN 2026-07-12, ALL VERIFIED: capture persisted; E1 mint A
-(refresh→exchange, aud=mcp-a, cache row refresh_token_ct NULL); E2 cache hit (0
-extra KC calls); E3 mint B from the SAME credential (aud=mcp-b); E4 rotation
-write-back (KC rotated the RT on the refresh leg, newest persisted); E5
-force_refresh re-mint (**2 KC calls** = the two-leg chain); E6 unconsented C →
-refresh_failed_transient (KC returns invalid_request for a missing audience
-scope → classified transient; credential SURVIVES either way); E7 flush→re-mint.
-Gotcha: dev-mode Keycloak boot is slow on a loaded host — the script now waits on
-kcadm auth (up to ~6 min) rather than a fixed sleep. Port 8091 (8090 = the dev
-console).
-
-## Leg 1 — Entra (`entra_spike.py`) — NEEDS TENANT ACCESS
-
-### Tenant / app-registration setup (one-time, ~15 min)
-
-1. **Spike client app** (stands in for Turnstone's OIDC app registration):
-   - New app registration, single tenant. Platform **Web**, redirect URI
-     `http://localhost:8765/callback`. Create a **client secret**.
-2. **Two resource apps** (stand in for MCP servers A and B):
-   - New app registrations `spike-mcp-a`, `spike-mcp-b`. In each:
-     **Expose an API** → set Application ID URI (`api://<guid>`) → add a scope
-     (e.g. `mcp.access`).
-3. **Delegated grants** (this is metaclassing's "proper tenant and app reg setup"):
-   - On the spike client app → **API permissions** → add delegated permission to
-     `spike-mcp-a` and `spike-mcp-b` scopes → **Grant admin consent**.
-   - Optionally also add the spike client's app id to each resource app's
-     `preAuthorizedApplications` (Expose an API → Add a client application) to
-     compare against pure admin consent.
-4. **Unconsented control** (for V5): a third resource app `spike-mcp-c` with an
-   exposed API but NO permission granted to the spike client.
-
-### Run
-
-```bash
-export ENTRA_TENANT_ID=... ENTRA_CLIENT_ID=... ENTRA_CLIENT_SECRET=...
-export SPIKE_AUDIENCE_A=api://<a-guid> SPIKE_AUDIENCE_B=api://<b-guid>
-export SPIKE_AUDIENCE_UNCONSENTED=api://<c-guid>   # optional (V5)
-export SPIKE_RUN_OBO=1                              # optional (V6)
-uv run python scripts/obo-e2e/entra_spike.py
-```
-
-A browser opens for one interactive login (any tenant user). Everything after is
-non-interactive — that IS the feature.
-
-### What each check pins down
-
-| Check | Design assumption it verifies |
-| --- | --- |
-| V1 | `offline_access` on the login yields a client-bound RT (capture layer) |
-| V2/V3 | ONE RT redeems for access tokens of DIFFERENT audiences (`scope=<aud>/.default`) — the load-bearing Entra behavior |
-| V4 | rotation semantics → whether RT write-back on every mint is convenience or correctness-critical |
-| V5 | unconsented audience fails `AADSTS65001 consent_required` → maps to the reconnect-rail fallback, never a silent failure |
-| V6 | OBO jwt-bearer middle-tier variant works with the same app registration (comparison data only) |
-
-Also record (manual): whether Conditional Access / MFA policies in the tenant
-produce `interaction_required` on redemption — that's the fallback path's other
-trigger.
-
-### Results — RUN 2026-07-11 on a real tenant, ALL SIX VERIFIED
-
-Tenant: personal default directory (Global Admin), user is an MSA member.
-Setup via `entra_setup.sh setup`; V3 initially failed (see gotcha below),
-passed after fixing the grant. Second run: V1-V6 all VERIFIED, exit 0.
-
-| Check | Result |
-| --- | --- |
-| V1 offline_access login -> RT | VERIFIED (confidential client + PKCE, RT ~2KB) |
-| V2 RT -> audience A token | VERIFIED (`aud=<A app guid>`, ~70 min TTL, new RT returned) |
-| V3 SAME RT -> audience B token | **VERIFIED — the load-bearing claim: one RT, many audiences** |
-| V4 rotation | VERIFIED: RT rotates on every redemption, but the OLD RT stays valid (reuse HTTP 200) -> write-back-newest is required; races are benign on Entra |
-| V5 unconsented audience | VERIFIED: `invalid_grant` + `AADSTS65001` (error_codes=[65001]) -> clean mapping to the reconnect-rail fallback |
-| V6 OBO jwt-bearer variant | VERIFIED: middle-tier shape also works with the same app registration |
-
-**Operator gotcha (feeds #682 + product docs):** `az ad app permission
-admin-consent` run immediately after SP creation SILENTLY skips
-not-yet-propagated resource SPs — grant A landed, grant B didn't, and the only
-symptom was AADSTS65001 at redemption. Verify grants after consent
-(`oauth2PermissionGrants` filter on the client SP) or write them directly with
-`az ad app permission grant --id <client> --api <resource> --scope <scope>`.
-Product-side implication: a missing tenant grant for a NEW oauth_obo server
-surfaces as AADSTS65001 -> the same reconnect-rail path as revocation; the
-admin docs must say "grant first, then add the server".
-
-## Leg 2 — Keycloak RFC 8693 (portability check) — runnable locally
-
-Ephemeral `quay.io/keycloak/keycloak:26.3` (`start-dev`, port 8089), realm
-`spike`, confidential client `turnstone` with **standard token exchange**
-enabled, resource clients `mcp-a`/`mcp-b`, user `alice`. Pipeline mirrors the
-product design for a generic-8693 IdP:
-
-```
-stored user RT --(refresh grant)--> user AT --(RFC 8693 exchange, audience=mcp-X)--> audience-scoped AT
-```
-
-i.e. the per-user credential stays ONE refresh token; per-server tokens are
-minted via standard token exchange instead of Entra's multi-resource RT
-redemption. Same substrate, different grant leg.
-
-### Results — RUN 2026-07-11, VERIFIED (Keycloak 26.3, ephemeral)
-
-```
-alice ONE stored RT
-  -> refresh grant                      -> user AT (azp=turnstone); RT ROTATED on refresh
-  -> 8693 exchange audience=mcp-a scope=aud-mcp-a -> AT aud=mcp-a user=alice 300s, NO RT
-  -> 8693 exchange audience=mcp-b scope=aud-mcp-b -> AT aud=mcp-b (same subject AT)
-  negative control audience=mcp-c       -> invalid_client "Audience not found"
-```
-
-Findings that feed the design:
-1. **One per-user credential -> N audience tokens: VERIFIED on a second IdP.**
-   The substrate is portable; only the grant leg differs per IdP.
-2. **Exchanged tokens are cache-shaped** (short TTL, no RT) — per-server
-   `mcp_user_tokens` rows as short-lived mint cache is the right model.
-3. **RT rotation happens here too** — newest-RT write-back on every redemption
-   is a correctness requirement of the capture layer, not an Entra quirk.
-4. **The IdP-side "delegated grant" has a per-IdP shape**: Entra = API
-   permissions + admin consent; Keycloak = audience client scopes attached to
-   the requester client (optional scopes activate via `scope=` at exchange).
-   Operator runbooks are per-IdP (#682 pattern), code is not.
-5. Gotchas hit: KC user needs a complete profile for direct grant ("Account is
-   not fully set up"); optional audience scope must be requested explicitly or
-   the exchange 400s with "Requested audience not available".

-"""End-to-end exercise of the oauth_obo feature against a REAL Entra tenant.
-
-Unlike ``entra_spike.py`` (which verified the raw OAuth wire shapes), this
-drives the ACTUAL Turnstone product code — real ``MCPTokenStore``, real
-``get_obo_access_token_classified`` → ``_obo_mint_entra`` → the real Entra
-token endpoint — so a green run proves the shipped mint engine works against
-live Entra, not just that the protocol does.
-
-Flow:
-  1. Interactive Entra login (auth-code + PKCE + offline_access) → a real
-     refresh credential. This is what ``handle_oidc_callback`` receives.
-  2. Persist it via ``MCPTokenStore.upsert_oidc_credential`` — the exact call
-     the OIDC callback makes on capture (auth.py). The rest of the callback
-     (JWKS validation, user provisioning) is OIDC-generic and unit-tested; the
-     novel path is capture + mint, which this exercises for real.
-  3. Seed real ``oauth_obo`` ``mcp_servers`` rows (audiences A/B consented, C
-     not) and drive ``get_obo_access_token_classified`` — the real dispatch-time
-     entry point — asserting on the minted tokens, cache, rotation, and
-     classification.
-
-Checks (VERIFIED / FAILED per line):
-  E1  mint for audience A → kind=token; decoded aud == A; cache row written with
-      refresh_token_ct NULL (cache, not custody); expires_at set
-  E2  second call for A → cache hit, ZERO additional Entra calls
-  E3  mint for audience B from the SAME captured credential → aud == B
-      (the single-credential-many-audiences thesis, through the real engine)
-  E4  rotation write-back: the stored credential holds the newest refresh token
-  E5  force_refresh → a fresh mint (Entra call count increments)
-  E6  unconsented audience C → NOT kind=token, and the shared credential SURVIVES
-      (never auto-deleted — the load-bearing custody invariant)
-  E7  cache flush → re-mint: deleting the cache row makes the next call re-mint
-
-Run:
-  source scripts/obo-e2e/.env

-  V1  interactive confidential-client login (auth-code + PKCE + offline_access)

-  V3  SAME credential redeemed for <AUDIENCE_B>        -> aud claim == B
-      KEY CHECK: Entra RTs are client-bound, not resource-bound.
-  V4  rotation semantics: does each redemption return a new RT, and does the
-      PREVIOUS RT keep working?                        [write-back design]
-  V5  redemption for an unconsented audience -> AADSTS65001 consent_required

-  E2 second call → cache hit, ZERO extra Keycloak calls
-  E3 audience B from the SAME captured credential → aud carries B
-  E4 rotation write-back (KC rotates the RT on the refresh leg)
-  E5 force_refresh → re-mint (Keycloak call count increments)
-  E6 unconsented audience C → NOT token, credential SURVIVES

-#!/usr/bin/env python3
-"""Browser-level SSE recovery livepass — boots the REAL interactive.js
-``InteractivePane`` against a REAL Turnstone node and drives the two
-headline recovery scenarios through headless Chrome over CDP, stamping
-``document.title`` verdicts (``RECOVERY-READY-*`` / ``RECOVERY-FAILED-*``)
-the livepass convention.
-
-Unlike ``scripts/livepass.py`` (which stubs ``window.authFetch`` with
-canned fixtures), this page uses the REAL auth + REAL EventSource against a
-REAL node: the page is served same-origin by the node itself (so cookie
-auth and EventSource just work), the node runs a scripted-provider
-workstream so a REST ``/send`` drives a real bash storm, and the pane's
-own state machine (interactive.js) does the recovery.
-
-Usage::
-
-    python3 scripts/recovery_e2e.py                 # run all three scenarios
-    python3 scripts/recovery_e2e.py --scenario storm
-    python3 scripts/recovery_e2e.py --scenario restart
-    python3 scripts/recovery_e2e.py --scenario coord-restart
-    python3 scripts/recovery_e2e.py --scenario both   # A+B only (legacy)
-    python3 scripts/recovery_e2e.py --keep-open 8971  # serve the storm page
-                                                      # for manual inspection
-
-Scenario A (storm): the page connects, POSTs ``/send`` on stream-open (so
-the listener is registered first), the node runs a 4-parallel-bash
-``seq 1 500`` storm plus a task_agent whose sub-tools are chatty bashes;
-the page asserts the final DOM has the expected top-level tool rows, the
-task_agent card nests its sub-tool rows (NO child escaped to the top
-level), and the composer settles idle. Stamps ``RECOVERY-READY-STORM-<n>``.
-
-Scenario B (hide mid-turn -> restart -> show): the runner hides the tab
-the moment the first streamed line paints (freezing the pane's cursor at
-a mid-turn event id — the MessageEvent ``lastEventId`` capture is what
-makes that cursor real; the pre-2026-07 object-form read left it null and
-this whole path unassertable), lets the turn and a follow-up text commit
-while hidden, restarts the node on the SAME port (fresh empty ring,
-storage-seeded counter), then shows the tab.  The show-edge reconnect
-presents the stale cursor, MUST draw ``replay_truncated`` (asserted:
-trunc>=1), the truncated resync rebuilds from /history, and the turns
-committed during the hide window MUST be present afterwards (asserted:
-``healed`` — the 'turn disappeared' field symptom).  Stamps
-``RECOVERY-READY-RESTART-rows<n>-trunc<n>``.  The exact ``lost_count``
-arithmetic and the failed-resync retry stay at the server-contract level
-in Tier 1's ``test_restart_truncated_honesty`` /
-``test_failed_resync_retries_via_truncation_record``.
-
-A NOTE ON THE BROWSER OVERFLOW (server-side poison): a real listener-queue
-poison needs the browser to STOP reading the socket so TCP backpressure
-reaches the server. A backgrounded/CPU-throttled tab does NOT do this --
-Chrome's network stack keeps draining the socket regardless of JS
-throttling, and interactive.js deliberately CLOSES the stream on tab-hide
-rather than starving it. So the server-side overflow -> stream_overflow ->
-reconnect path is NOT reliably forcible from a real browser (which is why
-that field bug was subtle); it is proven at the server-contract level in
-``tests/test_sse_recovery_e2e.py::test_slow_consumer_overflow_then_lossless_reconnect``.
-Scenario A here proves the OTHER half at the browser level: fix-3's
-de-amplified storm renders correctly with no escaped sub-agent children.
-
-MANUAL RUNBOOK (if Chrome/CDP is unavailable): run this with
-``--keep-open PORT`` to boot the node + serve the storm page, open the
-printed URL in a browser (the script prints the auth cookie to set), and
-watch ``document.title``. For the restart scenario, boot with a fixed
-port, load the restart page, background the tab, restart the node
-(``RecoveryServer`` on the same port), foreground the tab, and watch the
-title settle to ``RECOVERY-READY-RESTART``.
-
-Scenario C (coord-restart): the REAL coordinator pane
-(console/static/coordinator/coordinator.js — the #882 parity port of the
-same truncated-recovery machinery) driven through the SAME hide -> restart
--> show sequence as Scenario B.  The coordinator only runs under the
-console app in production, and the console's coordinator subsystems build
-inside its server lifespan against a config-resolved model registry — no
-``create_app(prebuilt SessionManager)`` seam for this harness's scripted
-provider.  So the scenario mounts the pane against the interactive
-recovery node instead: the node serves the console's coordinator static
-tree at ``/coord-static`` (a distinct prefix — the node's own ``/static``
-mount would swallow the console path) and a pane-only page at
-``/coord-recovery``; the pane's module imports are all absolute
-``/shared/*`` and resolve against the node.  Fidelity caveats, all inert
-for the recovery machinery under test: the workstream is
-interactive-kind (no coordinator status events — the status bar keeps its
-placeholder), and ``/children`` + ``/tasks`` 404 here (the pane's loaders
-catch and render empty by design).  What IS real: the full chrome
-(buildCoordChrome), cookie auth, EventSource + MessageEvent cursor
-capture, the connect chokepoint, the dead-stream resync
-(loadHistoryThenReconnect), the churn limiter, and the jitter.  Asserted:
-the show-edge reconnect draws ``replay_truncated`` (trunc>=1, counted at
-the transport by a page-side EventSource wrapper — the coordinator's
-handleEvent, cursor, and even its SSE indicator are closure-private or
-deliberately absent from the chrome), the resync rebuilds from /history
-with the hidden-window turns present (``healed``), tool rows intact, the
-stream re-opened post-show, the status bar not stuck dim, and idle
-asserted server-side by the runner.  Stamps
-``RECOVERY-READY-COORD-rows<n>-trunc<n>``.
-
-MANUAL COORDINATOR RUNBOOK (real console topology, no CDP): boot a dev
-console + one node (docker-compose dev cluster), open a coordinator with
-running children, hide the tab mid-turn, restart the CONSOLE process (the
-coordinator ring lives there), show the tab, and verify: the pane draws
-one truncated full rebuild (no blank pane), the mid-run turn's tool rows
-re-appear inside their batch (no standalone top-level orphan bubbles),
-and turns committed while hidden are present.

-"""Browser-fidelity SSE recovery harness helpers.
-
-The load-bearing assembly for ``tests/test_sse_recovery_e2e.py``: a
-``BrowserlikeSSEClient`` that speaks the exact wire contract the real
-``turnstone/shared_static/interactive.js`` pane speaks, and the
-assertion helpers the scenarios share. The server boot machinery lives
-in ``_sse_recovery_server.py``.
-
-Why a raw-socket SSE reader (and not ``httpx.stream``): the slow-consumer
-overflow scenario needs the consumer to STALL — stop reading the socket
-so the server's SSE generator blocks on ``await send`` and stops draining
-the per-UI listener queue, which then poisons at its cap. A faithful
-stall needs (a) precise control over when bytes are read and (b) a small
-``SO_RCVBUF`` so the in-flight backlog before poison stays bounded to
-~100 KB instead of the client kernel's multi-MB autotuned default (which
-would need tens of thousands of events to overflow). A raw socket gives
-both; httpx (used here only for the plain ``/history`` request/response)
-gives neither. This is ALSO closer to the browser: EventSource has a
-bounded receive buffer, not an unbounded one.
-
-Client contract mirrored from interactive.js (line references are to
-that file on the ``fix/sse-truncated-resync`` branch):
-
-- ``_last_event_id`` advances ONLY from SSE ``id:`` fields, and only
-  ring-buffer events carry one — synthetic replay frames (connected /
-  status / state_change / in_progress_snapshot / replay_truncated /
-  stream_overflow) do not, exactly like ``EventSource.lastEventId``
-  (interactive.js onmessage ~1378).
-- reconnect presents ``connectCursor = _truncatedFromCursor ??
-  _lastEventId`` as ``?last_event_id=`` (manual path) or a
-  ``Last-Event-ID`` header (native EventSource auto-reconnect path)
-  (interactive.js connectSSE ~1328).
-- on a ``replay_truncated`` envelope the client records the
-  truncation-time cursor keep-oldest (``_truncatedFromCursor =
-  _lastEventId`` only when null) and runs ``_loadHistoryThenConnect``
-  (disconnect → /history → adopt cursor → reconnect); a FAILED
-  /history leaves the record armed so the reconnect re-presents the
-  truncation-time cursor and re-draws the envelope (interactive.js
-  handleEvent replay_truncated ~2303, _loadHistoryThenConnect ~1604,
-  _refetchHistory seedCursor ~1706).

-"""Boot the REAL interactive Turnstone server for the SSE recovery e2e
-harness: real ``SessionManager`` + real ``ChatSession`` engine driven
-through a scripted chat-completions client at the SDK boundary, executing
-REAL bash tools, exposed over a real uvicorn socket.
-
-The recipe (verified end-to-end) has four load-bearing pieces:
-
-1. **Provider injection seam.** ``create_app`` takes a PRE-BUILT
-   ``SessionManager``, so the harness owns the ``session_factory``: it
-   passes ``client=fake_client`` and OMITS the registry, so
-   ``ChatSession`` falls back to ``create_provider("openai-compatible")``
-   == ``OpenAIChatCompletionsProvider`` — exactly what
-   ``tests._session_helpers.scripted_chat_client`` targets. No production
-   monkeypatch of the engine.
-
-2. **Auto-title suppression.** The first user message spawns a background
-   ``_generate_title`` LLM call that would consume the first scripted
-   response (the tool call) and desync a positional script. Setting
-   ``session._title_generated = True`` before the first send disables it.
-
-3. **Completion barrier.** ``/send`` returns immediately after spawning
-   ``ws.worker_thread``; joining that thread is the true "turn complete,
-   every SSE event enqueued" barrier (``stream_end`` is per-LLM-call, not
-   per-turn, so it is NOT a completion marker).
-
-4. **Thread hygiene.** ``create_app``'s lifespan unconditionally starts
-   two daemon fan-out threads (``_global_fanout_thread`` blocking on
-   ``global_queue.get()``, ``_aggregate_emitter_thread`` on a 10s loop)
-   with no shutdown sentinel — they would trip conftest's leaked-thread
-   guard. They serve the cluster/global lane, which the per-ws ``/events``
