Patrick Buckley 1f9f462b66 fix(streaming): gate the dead-segment discard on the backoff surviving the Stop window
Fifth review round — four small correctness edges, none in the retry
semantics:

- The server-buffer discard now runs only AFTER the backoff survives a
  Stop: a cancel during the window persists the promoted partial to
  history, and the idle-state payload (drained from the turn buffer)
  must carry the same text — discarding first rendered the cancelled
  turn empty on the dashboard while the transcript had it. Pinned with
  a real-buffer test; the spinner and fresh segment watermark follow
  the truncate so a later discard cannot resurrect the dead segment.
- stream.retry's dead_content_chars reports THIS death's flushed text
  only — the Stop-preservation carry retains the previous attempt's
  partial by design, and logging its length re-attributed the same
  discarded spend to consecutive retry lines.
- The changelog entry for the post-finish-blip rename no longer claims
  the usage_captured field was dropped; it is emitted and pinned.
- The retry suite's module docstring states the shipped finalize
  contract (stream_end + backoff-gated stream_discarded, never
  turn_committed) instead of the superseded pair.
- RecordingUI is hoisted into tests/_session_helpers next to NullUI —
  this branch already paid the per-file-fake tax once when a protocol
  method grew — and a stale deferral sentence is dropped from the
  fatal-formatter comment.

Changelog

All notable changes to turnstone are documented here.

The format is based on Keep a Changelog, and this project adheres to PEP 440 for version numbers (X.Y.Z, with X.Y.ZaN / bN / rcN for pre-releases).

Two active release tracks are maintained — the current stable and the experimental line:

  • stable/1.7 — patch-only (v1.7.x)
  • main — experimental (next major)

Earlier stable lines (stable/1.6, stable/1.5) are frozen.

[Unreleased]

Added

  • Per-model Entra gateway authentication. Model definitions can bind either a caller-delegated OBO token (entra_obo) or a shared app-identity token (entra_app) through the provider SDK credential surface. Mints reuse the encrypted cluster token cache, refresh-rotation CAS, and advisory locking; add a host-local memo, failure cooldown, long-lived mint HTTP client, audience allow-list/permission boundary, identity-unlink purge, and optional model.auth_fail_closed refusal policy. Delegated identity now propagates through judge, output-guard, and principal-scoped perception lanes, and unattended watch restoration reacquires the persisted workstream owner. Ownerless OBO calls and dynamic aliases without a real static fallback always fail closed; grant modes are never silently switched. Static authentication remains the default.

  • 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

  • Log event rename: drain_stream.post_finish_blip is now stream.post_finish_blip; its usage_captured field is retained. The single-shot drain normalizes mid-body transport deaths through the same transport_guarded wrapper the interactive loop uses, so its post-finish-blip tolerance logs under the wrapper's event name. Update any external log filters pinned to the old name; the drained result's possible usage=None on a post-finish blip is unchanged and documented on drain_stream.

  • 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 transport failure mid-generation no longer kills the interactive turn (#937). A wire death during body streaming (TLS record failure, connection reset — httpx.ReadError and kin) surfaces after the request has already returned its stream handle, so neither the SDK's request retries nor the creation-time retry ladder ever saw it: the turn died with a bare ReadError: …, the partial output was discarded, and nothing was logged. The interactive loop now normalizes mid-body transport deaths exactly like the single-shot lanes and re-issues the turn (bounded, cancel-aware, exponential backoff), finalizing the dead attempt across every UI surface first so retried text never double-renders (web transcript, CLI markdown fences, Slack/Discord streamed messages). Before re-creating the stream the session re-resolves its registry binding, so a concurrent model-registry reload that closed the old client cannot turn the retry into a misleading closed-client error. On exhaustion the surfaced error names the provider, endpoint, and model with a stream-death message instead of a bare exception string, and every fatal turn now leaves a session.fatal.recorded log line (INFO for a user Ctrl-C, ERROR otherwise).

  • 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 062065, 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 floorscryptography 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.

[1.6.0]

The first stable release of the 1.6 line — and the first under Apache 2.0.

⚠️ Before upgrading from 1.5.x: 1.6.0 changes the internal conversation storage schema (Alembic migration 060, applied automatically on first start). The migration converts existing workstreams and attachments in place — back up your storage before upgrading (pg_dump for PostgreSQL; copy the database file for SQLite). Background: discussion #631.

Breaking changes at a glance (details in the sections below): web_search backend overhaul (Tavily/DuckDuckGo removed, topiccategory), the man / math / plan_agent built-in tools and the plan-review protocol removed, and the body-keyed /v1/api/command endpoint replaced by path-keyed workstream verbs.

License

  • Relicensed to Apache 2.0 — from BUSL-1.1, effective with this release (#546, contributor assent record in #548). Versions 1.5.x and earlier remain under BUSL-1.1 as shipped, and the stable/1.5 branch keeps its original LICENSE. New NOTICE and CONTRIBUTORS.md files; THIRD-PARTY-NOTICES refreshed to match the bundled library versions.

Added

  • Mid-conversation system messages — advisories, watch results, skill hints, and operator interjections are now first-class role=system turns in the trajectory instead of ad-hoc reminder envelopes. Models with native mid-conversation system support receive them verbatim; for everything else they fold into a nonce-fenced wrapper. The one-shot _reminders side-channel is gone.
  • Self-hosted SearxNG web search — the web_search backend for local/vLLM models is now a bundled SearxNG service (in both compose stacks; internal network only). Configure via tools.searxng_url / tools.searxng_engines. Commercial providers keep their native server-side search; the model can target a corpus by passing category (general, news, it, science). Operators exposing the bundled SearxNG publicly: see the AGPL-3.0 §13 note in docs/docker.md.
  • Endpoint-backed reranking — a reranker is now a per-model definition (Cohere/Jina-compatible wire: vLLM, TEI, llama.cpp, or a commercial endpoint), disabled by default. When configured it scores web_search results and the BM25 retrieval surfaces (deferred tools, skills, memory) behind a tools.rerank_bm25 toggle with a relevance floor; a calibration CLI (and calibrate-on-detect) tunes the floor per model.
  • Proactive memory relevance — injected memories are selected by BM25 + reranker against the recent user messages instead of recency alone, and first composition defers to the first user turn so fresh sessions select against a real query.
  • Smart Approvals — opt-in (default off): high-confidence approve verdicts from the intent judge auto-approve the tool call instead of waiting for a human, with a confidence threshold and verdict bookkeeping designed so a denied or reset judge never auto-fires.
  • Early-painted tool calls — committed tool calls render immediately as pending cards (both UIs upgrade the card in place by call_id) instead of waiting for the judge verdict, so big parallel batches no longer sit invisible during judging.
  • Voice I/O v1 — speech-to-text and text-to-speech as model roles speaking the OpenAI audio wire protocol (#618); the interactive composer grows a mic button.
  • Rewind / retry / edit-first-message — full UX in both the interactive UI and the coordinator pane, backed by shared path-keyed verb handlers (#549).
  • Workstream export — download a conversation as OpenAI-format messages JSON.
  • Skills platform roundSKILL.md ingestion learns when_to_use / model / effort / paths; prompt substitution supports $ARGUMENTS, $N, $<name>, and ${CLAUDE_*} (#572); per-skill disable-model-invocation and user-invocable flags (#571); skill + list_skills unify into one dual-kind tool; new model.skills.write permission.
  • Coordinator hardening for small models — workstream references in coordinator tool calls are validated with did-you-mean recovery, and wait_for_workstream fails fast with uniform not_found entries instead of hanging on a hallucinated ws_id.
  • Provider support — Claude Fable 5 and Claude Opus 4.8; xAI/Grok via the OpenAI Responses lane; vLLM reasoning-field replay completes the reasoning-persistence work (#537).
  • Cluster-by-default deployment — the compose stack fronts everything with Caddy and supports bare-metal node join; a one-line curl | bash installer bootstraps a node; nodes with no configured models boot into a degraded state instead of crash-looping; channel gateways stand by when no adapter token is set.
  • MCP OAuth tokens encrypted at rest.
  • turnstone-admin reads config.toml — same [database] section and precedence as the server (`CLI / config.toml > TURNSTONE_DB_* env

    defaults), including pool_sizeand thessl*knobs it previously dropped; new--config PATH` flag.

Changed

  • Conversation storage and the provider wire are rebuilt around a canonical trajectory (migration 060 — see the upgrade note). Internally a conversation is now a provider-neutral Turn sequence lowered to each provider's wire format at send time; provider-specific tool-call metadata rides an opaque producer-tagged lane (replayed verbatim to the producing provider, rebuilt for others); attachments become content-addressed, reference-counted rows resolved at the provider boundary; orphan tool-call repair happens once, at send time. Wire-visible behavior is unchanged for OpenAI-compatible providers; histories are preserved across the migration.
  • The console and web UI share one L-shell — a left glyph rail, a tab bar, and a pane host now frame interactive chats, coordinator sessions, dashboards, and the admin panel as tabs in a single window; the standalone web UI adopts the same shell and the old split-pane layout is retired. Coordinator and interactive conversations render through shared .conv-* card builders, the rail collapses to a glyph strip (remembered per browser), mobile gets an off-canvas drawer, and the frontend is now ES modules end to end.
  • Admin panel modals → the Service Hatch shelf — all ~35 admin modals are replaced by pane-scoped shelves plus a small dialog tier for confirmations. Schedules gain a cron builder with a next-3-runs preview endpoint, model capabilities render as an LED tile matrix, and the legacy modal machinery is deleted.
  • SSE delivery is resumable end to end — per-workstream ring buffer with Last-Event-ID replay (cap raised 2,000 → 50,000), fresh-connect and reconnect unified on one event-id cursor (in-flight tool batches included), persisted last_error replays on connect, the console proxy forwards Last-Event-ID, and panes close their connections on beforeunload to stop multi-pane refresh from exhausting the browser's per-host connection cap (#539).
  • Workstream verbs are path-keyed (BREAKING)rewind / retry / edit-first-message live at /v1/api/workstreams/{ws_id}/<verb> alongside the other session verbs; the body-keyed /v1/api/command endpoint is removed (#549).
  • /history is projected server-side — both UIs consume the same REST-first wire shape instead of re-deriving it client-side.
  • Saved workstreams & coordinators: card grid → sortable table with model/skill/context columns, pagination, and a unified selector across both dashboards.
  • tools.web_search_backend accepted values (BREAKING) — now "" (auto), "searxng", or "mcp:server:tool". The old "tavily" and "ddg" values are gone; a config still set to either disables web search and logs a warning. Auto-detect resolves to SearxNG when searxng_url is set.
  • web_search tool: topiccategory (BREAKING) — renamed LLM-facing parameter; values map to SearxNG categories. The Tavily-era finance topic is gone.
  • Core install includes what most deployments useanthropic, postgres, console, and tls are core dependencies rather than extras.
  • NODES table → bottom-bar node picker in the console.

Fixed

  • Cluster mTLS actually survives operations — certificate identity keys on the advertised host rather than the container ID, renewals are scoped per node, reloaded certs hot-swap into the live SSL context, and healthchecks/boot retries are mTLS-aware.
  • Intent-verdict lifecycle — history replay ships risk-none verdict rows (live/replay parity), late verdicts persist as superseded for the audit trail instead of vanishing, bulk verdict insert tolerates per-row conflicts, and cancel-on-approval honors its run-to-completion contract.
  • Usage accounting — dashboard totals were under-counting; auxiliary LLM spend (judge, rerank, memory) is now recorded.
  • Concurrent first-boot migrations no longer deadlock on the advisory lock.
  • Output renderer — single-$ inline math no longer false-positives in prose; strip_html preserves block structure and drops a ReDoS risk.
  • Model registry orders versions numerically (no more 1.10 < 1.9 selection).

Removed

  • Tavily and DuckDuckGo web_search backends (BREAKING) — replaced by the bundled SearxNG service. Removed: tools.tavily_api_key, $TAVILY_API_KEY, [api].tavily_key, and the ddg install extra. Point TURNSTONE_SEARXNG_URL at an existing instance or use the bundled one; no database migration required.
  • man, math, and plan_agent built-in tools (BREAKING)man/math duplicated bash; planning is better expressed as a task_agent running a planning skill. Also removed: the math sandbox executor, the read-only AGENT_TOOLS sub-agent set, the plan-review protocol (/v1/api/plan, plan_review/plan_resolved SSE events, on_plan_review hooks), and the model.plan_* settings. Interactive built-in tool count: 19 → 16.
  • stable/1.4 track retired — the maintenance policy is now the current stable plus one prior (stable/1.6 + stable/1.5 as of this release). 1.4's final release was v1.4.0; its tags and released artifacts remain available, under BUSL-1.1 as shipped.

Security

  • Zero direct-HTML frontend — every innerHTML sink across the console and web UI is replaced with DOM construction or setSafeHtml, inline handlers became delegated bindings, and CI lints pin the invariant (plus var-free and const-reassign checks) across all swept bundles.
  • Output guard grows an LLM stage — merged with the heuristics as escalate-only (an LLM verdict can raise but never lower a heuristic positive), with annotated findings, a capability gate, and hardening against domain-camouflaged injection (#560, #573).
  • One trust-fence primitive — operator and judge envelopes share a nonce-fenced wrapper (64-bit nonces, host-escaping); the output guard flags nonce forgery, and skill hints no longer echo model-controlled filter values into trusted text.
  • RBAC — built-in role overrides get an editor, and several under-enforced permission gates are tightened (#585).
  • Permissive config.toml warns — a single startup warning when the resolved config file is group- or world-readable; operators usually want 0600.
  • Dependency floorsstarlette>=1.0.1 (PYSEC-2026-161 host-header path injection) and aiohttp>=3.14.0 (security release).

[1.5.17]

Backports a clutch of coordinator-tool clarity fixes plus a watch-delivery correctness fix from main to the stable/1.5 track, plus a previously- latent intent-verdicts persistence bug exposed by the new heuristic-verdict INSERT paths. No schema changes.

Fixed

  • intent_verdicts PK collisions on every llm_fallback delivery — async LLM-tier "llm_fallback" verdicts (turnstone/core/judge.py_deliver_fallbacks and the in-loop fallback path) deliberately reuse the heuristic verdict's verdict_id so the row gets "upgraded in place" from tier="heuristic"tier="llm_fallback" when the LLM judge times out, is cancelled, or returns no content. The consumer _persist_intent_verdict was doing a plain INSERT, hitting the intent_verdicts_pkey constraint on every fallback delivery; Postgres logged the duplicate-key error, the application try/except swallowed it at log.debug, and the row never actually got upgraded — the LLM judge's annotation ("(LLM judge did not return a verdict)") was lost. The collision rate exploded on this release because the new heuristic-INSERT paths in the auto-approve early-return branches of approve_tools (introduced below) leave no gap for the fallback to land cleanly into. Fix: new upsert_intent_verdict storage method using ON CONFLICT (verdict_id) DO UPDATE that updates only tier, reasoning, judge_model — the three fields that genuinely change between heuristic and llm_fallback. Every other column (identity, carried-verbatim, and user_decision) is excluded; user_decision in particular would otherwise be clobbered back to "pending" when a fallback arrives after the operator has already resolved the approval. The bulk-INSERT path stays as plain INSERT — fresh UUIDs in judge.evaluate make in-turn dups impossible; the inverse race (fallback wins before bulk lands) is reachable but unchanged in observable behavior by this fix, documented at the bulk site for a future hardening pass.
  • Coordinator LLM re-spawn loops on large fan-outs — the spawn-tool return JSON used ws_id as its key, which primed the model's recency bias to feed the spawn result straight back into another spawn_workstream(ws_id=...) call instead of progressing to wait_for_workstream(ws_ids=[...]). On 10+ child fan-outs this cascaded into self-inflicted re-spawn loops. The LLM-facing tool result now emits child_ws_id (the storage column / HTTP API contract is unchanged); the field name is already an existing project term so the rename aligns rather than introduces new vocabulary. Also handles the silent upstream-omits-ws_id success-shape edge that previously emitted {"child_ws_id": null} to the LLM — now surfaces a tool error so the model retries rather than chasing a null id.
  • inspect_workstream blowing the coordinator context budget — a coord doing a fan-out wave against tool-heavy children could land

    100 KB of raw output per inspect call, and the previous safety net (_truncate_output's head+tail strategy) silently dropped middle messages — exactly the wrong shape for understanding a child's trajectory (the FIRST sets the brief, the LAST shows the conclusion, the middle is the connective tissue). Output now goes through a three-tier degradation ladder mirroring the search tool's _format_search_results: _tier="full" (every message verbatim) → _tier="compact" (per-message head/tail-snipped content + snipped tool_calls.arguments, falling through a (20,30) / (10,20) / (5,10) message-list trim ladder) → _tier="skeleton" (counts, role distribution, last-assistant preview). Budget 32 KiB matches the search tool's; the chosen tier is annotated on the response so the model can recall with a tighter message_limit if signal was lost.

  • Auto-approved verdicts indistinguishable from pending reviewintent_verdict rows for auto-approved tool calls landed with user_decision="", which read identically to "still waiting for the operator" in the audit trail and led to a real misdiagnosis incident. The column now carries an explicit vocabulary at insert: pending / approved / denied / timeout / policy / blanket / skill / always / auto_approve_tools. The auto-approve early-return branches in approve_tools now persist heuristic verdicts stamped with their reason (previously dropped on the floor), and late LLM-tier verdicts that arrive for an already-auto-approved call_id are stamped via a TTL-pruned lookup map — so the audit row carries the auto-approve reason even when the LLM judge daemon completes after the synchronous approval cycle finished. resolve_approval gains a timeout kwarg writing "timeout" (the previous shape collapsed passive timeouts and active denials into the same column).
  • list_skills empty allowed_tools misread as "no tool access" — the response previously emitted "allowed_tools": [] for every skill that hadn't declared an auto-approve allowlist, which a coordinator model read as "this skill can't use any tools" (real misdiagnosis: a code-review child appeared to have been spawned with zero tool access). The field is now omitted entirely when empty — absence carries the unambiguous meaning "no tool is pre-approved for this skill", presence (non-empty list) keeps the standard Claude Code skill-spec shape. The tool description rewrite makes the auto-approve-allowlist semantics explicit so a future reader doesn't re-derive the gating misread.
  • Watch terminal-fires silently dropped on backpressure — delivery now routes terminal events through the same path as normal fires instead of being filtered out when the consumer was saturated.

Documentation

  • Storage LIKE_ESCAPE contract — clarify that callers passing .like(escape=...) must use the same escape character that the storage helper assumes; previous wording let a reader pass a different escape and silently produce no matches.

[1.5.15]

Fixed

  • Admin console blank-page on MCP server rows with consented users — a Phase 9 (1.5.14) regression in admin.js used double-quote string delimiters on the bulk-revoke button HTML literal, but the literal embeds a " mid-attribute. JS closed the string early, turned bulk-revoke ( into bare tokens, and the resulting SyntaxError wiped out every global in admin.jsshowAdmin and all other admin entry points became undefined, so the console UI was non-functional whenever the rendered MCP server list contained at least one row with consented_users_count > 0. Switch the literal to single-quote delimiters to match the surrounding block.

[1.5.14]

Backports OAuth-MCP Phase 9 from main to the stable/1.5 track.

Added

  • OAuth-MCP Phase 9 — admin status, deferred-consent persistence, operator docs — completes the per-(user, server) OAuth-MCP build-out. The sync pool dispatchers now upsert into a new mcp_pending_consent table on mcp_consent_required / mcp_insufficient_scope, so a non-interactive run (scheduled / channel) that hits an unconsented server surfaces the deferred prompt to the user on their next dashboard load via the gear-icon badge — rows are cleared automatically by the OAuth callback handler on consent completion, or via new DELETE endpoints for manual dismiss. The MCP Servers admin row gains a consented_users_count pill and a two-step-confirm bulk-revoke button for auth_type=oauth_user servers (upstream RFC 7009 revoke is intentionally not attempted in bulk to avoid N synchronous round-trips against the provider). Operator-facing docs land at docs/mcp-oauth.md and docs/operations/mcp-oauth-headless.md.

    Introduces forward-only migrations 054_mcp_pending_consent and 055_mcp_user_tokens_server_index.

[1.5.13]

This release introduces one forward-only schema migration: 053_services_notify_trigger — installs the services_notify PostgreSQL trigger that backs the new LISTEN/NOTIFY dispatcher (no-op on SQLite, where the dispatcher uses in-process fan-out).

Added

  • Reactive node discovery via PG LISTEN/NOTIFY — the console gains a NotifyDispatcher that holds a dedicated session-mode PostgreSQL LISTEN connection (bypasses pgbouncer transaction pooling) and fans wake-ups out to per-channel handlers on a separate dispatch thread. The cluster collector subscribes to a new services channel and reacts to node register / deregister within ~500 ms instead of waiting up to 60 s for the next discovery loop; the 60 s loop is retained as the backstop for crash-shaped loss (NOTIFY only fires on real writes). The storage layer also gains a uniform notify / listen API with an SQLite synthetic-sweep fallback so consumer code is identical across backends. TURNSTONE_DB_LISTEN_URL (or [database] listen_url in config.toml) points the dispatcher at a direct-to-Postgres URL; defaults to the main DB URL when unset.
  • Event-driven wait_for_workstream — coord's block-wait tool no longer polls storage every 500 ms. A new in-process ChildEventBus notifies waiters whenever a child state change is dispatched to the UI, and the wait loop blocks on threading.Event.wait with a 2 s heartbeat cap (matching the existing wait_progress SSE cadence). A 600 s wait that previously hit storage ~2400 times now wakes only on real state transitions, with ~4× lower SSE traffic in the quiescent case.
  • Memory tool audit trail — the memory tool now emits memory.save, memory.update, and memory.delete audit events (the admin-console DELETE route previously emitted only memory.delete, so tool-initiated mutations had no audit footprint). All emissions are best-effort and never break the tool call itself.
  • task_agent per-call personas via skill=task_agent now accepts an optional skill=<name> argument that loads the named skill's content as the sub-agent's persona in place of the hardcoded identity statement. The fixed operating-guidance block (one-shot, tool-use over narration, no follow-up questions) is still layered on top of every persona. High- and critical-risk skills surface their risk tier in the approval header and emit a task_agent.high_risk_skill warning, matching the existing session-load gate.

Fixed

  • Per-role plan / task model overrides could be bypassed by the LLM — the back-compat default alias auto-synthesised by load_model_registry remained visible to the model even when an operator had configured model.task_alias / model.plan_alias, so task_agent(model="default") routed to whichever backend the synthesised alias was attached to at boot instead of the configured per-role default. The synthesised alias is now only added when neither the DB nor [models.*] populates the registry, filtered out of the LLM-visible alias list, and explicitly rejected at the validator chokepoint as defense-in-depth.
  • Mermaid streaming parse errors + progressive hljs — live-streamed mermaid blocks with bare (, [, { inside unquoted edge or rectangle node labels were re-entering the shape parser and producing Parse error, got 'PS' messages. The renderer now autoquotes the two affected label forms (|content| and ID[content]) before the SVG cache lookup; shapes whose syntax already nests delimiters (cylinders, subroutines, trapezoids, etc.) are intentionally left alone. The companion hljs change highlights code blocks progressively as they stream rather than only after completion.
  • Re-auth from inside the proxy-prefixed UI — on a proxied node page (/node/{id}/...), an expiring JWT triggered an in-page login modal whose POST went to /v1/api/auth/login and was rewritten to /node/{id}/v1/api/auth/login. Two latent bugs both blocked re-auth: the console's AuthMiddleware didn't recognise the /node/{id}/ prefix over a public path, and proxy_api would have forwarded the login request to the upstream node (which mints JWT_AUD_SERVER tokens the console then rejects). Both fixed: proxied public paths stay public, and proxy_api now dispatches every entry in _PROXY_AUTH_LOCAL_HANDLERS (login, logout, setup, refresh, status, whoami, oidc/authorize, oidc/callback) to the console's own auth handlers. The dispatch table is a single (method, path) → handler mapping so the test parametrize list can't drift from the implementation.
  • Appbar visibility + gear-icon dropdown on the dashboard — the dashboard overlay was covering the entire appbar, hiding the proxy-injected node picker. The overlay now starts at top: 48px and the dashboard's role downgrades from dialog+aria-modal to region so the appbar above it remains reachable. The gear icon converts from a direct settings-panel click into a dropdown with "MCP connections" and "Logout" (the latter with .destructive styling). The settings-menu keydown handler is now attached synchronously so Escape can't fall through the brief window between the menu opening and its listeners being installed.
  • PostgreSQL test backend on the notify dispatcher suite — migration 053's services_notify trigger lives only in the alembic chain, but the test fixture creates tables via metadata.create_all. The trigger function + trigger are now declared in _schema.py and attached via sa.event.listen(services, "after_create", ...) DDL events gated on the PostgreSQL dialect, with the same SQL constants imported by migration 053 so there's a single source of truth.

[1.5.12]

Added

  • Enriched backend error messages — provider name and attempted URL are now included in session error responses, so operators can triage connectivity failures without enabling debug logging.

Fixed

  • /rewind always emits a history SSE event — pre-fix, if the session had no messages remaining after a rewind the history event was skipped, leaving connected UIs with stale content and blocking edit-and-resend flows.

[1.5.11]

This release introduces one forward-only schema migration: 052_model_reasoning_persistencesurface_persisted_reasoning and replay_reasoning_to_model flag columns on model_definitions.

Added

  • SSE refresh-resume — clients that reload mid-stream (browser refresh, tab restore) now receive an in_progress_snapshot event carrying the buffered partial response, so the UI can resume rendering the in-flight turn without losing content. The snapshot is keyed by a monotonic _ws_inflight_seq counter so a reconnecting client can skip events it already saw.
  • Reasoning persistence (Phases 14) — model reasoning text can now be persisted to conversation history and optionally replayed to the model on subsequent turns. Phase 1 persists reasoning text on the history payload. Phase 2 wires a build-time shape filter and a per-model replay_reasoning_to_model flag. Phases 3+4 add full OpenAI Responses API (include=["reasoning.encrypted_content"]) and Chat Completions support; an ANTHROPIC_VALID_BLOCK_TYPES shape filter guards the Anthropic path. Two new per-model capability flags (surface_persisted_reasoning, replay_reasoning_to_model) both default False on unknown and local-server models.
  • Console home composer: placeholders + toggle — the console landing-page composer now shows context-aware placeholder text and a toggle component for advanced options; an admin polish pass tightened spacing and focus behaviour across the form.

Changed

  • judge.model now requires a named alias — raw provider model IDs on judge.model in config are no longer accepted; the judge must reference an alias registered in the model registry. The session-provider raw-model fallback is removed. Existing configs using an unregistered model ID need a corresponding alias entry.

Fixed

  • replay_reasoning_to_model AND-gated with model capability — setting the flag for a model that does not declare reasoning-replay support now silently no-ops instead of forwarding reasoning blocks and triggering a provider error.
  • Coordinator alias resolution unified across placeholder + factory — a placeholder coordinator and the real coordinator factory could previously resolve to different model aliases, producing a visible mismatch in the model display. Both paths now share the same resolution logic.
  • Console cs=None fallback in /v1/api/models placeholder — an under-initialised coordinator state no longer 500s when the models endpoint is hit before the coordinator subsystem is fully bootstrapped.
  • SSE _ws_inflight_seq always advances — sequence numbers were previously skipped when an emit was past the buffer cap, leaving gaps in the monotonic counter that broke state_change / in_progress_snapshot ordering on reconnect.
  • Reasoning persistence shape + replay fixes — per-block ANTHROPIC_VALID_BLOCK_TYPES filter applied; reasoning_text is now synthesised alongside non-reasoning provider_blocks so both appear together in the history payload.

[1.5.10]

This release introduces one forward-only schema migration: 051_skill_notify_on_complete_array_default — backfills prompt_templates.notify_on_complete from '{}' to '[]'.

Added

  • Skills unlock action — operators can unlock an installed skill to allow local customisation. Once unlocked, the skill's resource content, system prompt additions, and notify configuration are editable through the admin UI. Skills shipped as part of a bundle remain locked (read-only) until explicitly unlocked; the unlock is logged to the audit trail. A lock icon in the top-right of the Skills detail pane doubles as the unlock trigger.

Fixed

  • skills.sh install endpoint — the install script was targeting an endpoint removed in an earlier refactor; switched to /api/download.
  • Skills notify_on_complete default — the field defaulted to {} (object) instead of [] (array), causing notify configurations to be rejected at schema validation.
  • Skills admin UI modal errors.is-visible class used consistently instead of inline style.display; stale error text is cleared on submit; designer-review lock-icon UX applied.

[1.5.9]

Fixed

  • repair=False on all display-read load_messages call sites — passing repair=True on display paths was silently mutating the stored message list, causing divergence between what the UI showed and what the model received on the next turn.

[1.5.8]

This release introduces two forward-only schema migrations: 049_mcp_oauth_schema — OAuth token + consent tables for MCP servers; 050_conversations_source_and_reminders_source and _reminders columns on conversations.

Added

  • MCP OAuth 2.1 + PKCE — MCP servers that require OAuth can now be configured with a client ID and secret through the admin UI. The full token lifecycle (acquire → refresh → rotate) is managed automatically; tokens are stored encrypted at rest using a key derived from the JWT secret. The consent flow runs in-browser via a provider redirect. Rolled out in phases:

    • Minimum admin form and OAuth schema (21663d15).
    • Token-at-rest AES-GCM encryption layer (a4c335d7).
    • Per-(user, server) OAuth 2.1 + PKCE flow (b0f7029f).
    • Per-(user, server) ClientSession pool with OAuth dispatch (1a1043c4).
    • SDK 401/403 introspection via httpx response hook (bde09134).
    • Phase 7 — per-user tool catalog scoping: each user sees only the tools their OAuth token is permitted to call (cfc8a6c8).
    • Phase 7b — per-user resource + prompt pool dispatch (b368bdee).
    • Phase 8 — per-user MCP consent UX: users see a consent dialog on first use of an OAuth-gated server and can revoke consent from their profile; admins see per-server consent counts in the MCP Servers tab (61051339).
  • Metacognition NudgeQueue — all advisory channels (repeat-tool nudges, watch reminders, wake triggers) are unified into a pull-model NudgeQueue that delivers at most one nudge per turn, preventing multi-channel pile-ups that inflate context. Observable changes:

    • Watch results carry metadata (watch ID, valid_until, trigger type) through to the system message so the model can reason about recency.
    • Coordinator idle-children observer: a coordinator with no in-flight children for longer than the configured idle threshold receives a nudge.
    • Wake trigger (IdleNudgeWatcher): sessions waiting on an external event can be unblocked via ChatSession.deliver_wake_nudge_from_queue.
    • Watch switchover: watch results are now enqueued on the NudgeQueue rather than the previous _watch_pending list, giving them the same delivery guarantees and priority handling as other advisories.
  • Structured watch-result card — the UI renders watch results as a styled card with a system-nudge marker, distinct from the assistant message body. On history replay, system-nudge turns are visually distinguished from normal assistant turns.

  • Side-channel persistence_source and _reminders side-channel fields are persisted to the conversations storage table and restored on session resume, so metacognitive context survives process restarts. A REMINDER_TEXT_STORAGE_CAP byte clamp prevents unbounded growth.

Fixed

  • Replay consistency — queued user messages captured mid-loop are now persisted and replayed in the correct order on a subsequent events subscription. Coordinator history replay fixed: blank assistant cards and out-of-order tool results on the coordinator tree no longer occur when the coordinator has mixed queued + delivered messages.
  • Session reminder preservation on fork + resume_source and _reminders are carried through workstream fork and restored from storage on resume.
  • NUL-byte sanitization in storage — PostgreSQL rejects \x00 in text columns; _source and _reminders now strip NUL bytes on write.
  • Console coordinator subsystem bootstrap — the coordinator subsystem is now committed atomically on first model add; startup teardown is offloaded to avoid blocking the event loop.
  • MCP asyncio.timeout over asyncio.wait_for — Python 3.11's wait_for wraps the coroutine in a fresh task, breaking anyio's aclose scope exit. Replaced with async with asyncio.timeout(N) for safe cleanup.
  • MCP pool-reuse 401 recovery — a reused ClientSession returning 401 now replaces the pool entry with a fresh session; the carrier token is owned by the pool entry to prevent a race between the 401 handler and a concurrent request.
  • OIDC hardening — multiple security and correctness fixes: SSRF + plaintext credential exfil via discovery document (sec-1, sec-3); TURNSTONE_OIDC_REDIRECT_BASE now required, Host-header fallback removed (sec-2); atomic user + identity provisioning prevents orphan rows (bug-1); callback robustness — typed exceptions, shape checks, log sanitization, JS race (bug-46, sec-4); role-mapping concurrency serialized (bug-2, perf-1); stranded-user self-heal on role-mapping failure (cumulative bug-1).

[1.5.7]

Added

  • Inline node picker — a compact node-switcher dropdown in the console header replaces the "← Back to console" banner, so operators can switch between nodes without a full navigation.

Fixed

  • Queued user messages injected mid-loop — messages queued while a generation was in progress were not being delivered at the correct seam and could be dropped or reordered when the worker consumed the queue.
  • Search tool output bounded — pathological inputs (very long lines with no whitespace) could produce search results exceeding the context budget. Output is now clamped before reaching the message.

[1.5.6]

Added

  • api_surface toggle — model definitions gain an api_surface field ("chat" | "responses") that selects which OpenAI-compatible API surface the provider client uses. Enables Mistral Medium reasoning via the Responses surface; Chat Completions remains the default for all other models.
  • Healthy model aliases per nodeGET /v1/api/cluster/nodes now includes a healthy_aliases list per node, so the coordinator and operators can see which model aliases are currently reachable without a separate per-model health probe.
  • Plan/task agent settings in Models → Roles — the Models admin tab's Roles sub-tab gains plan_agent and task_agent rows so operators can configure per-kind reasoning effort and alias overrides from the UI rather than editing config.toml. Live-refresh dropdowns update in place when model definitions change.

Fixed

  • Memory candidate selection — recall now uses OR-of-terms BM25 with query-aware candidate-set selection, dramatically improving recall for queries whose terms span multiple stored entries.
  • Workstream model + config preserved on rehydrate — reopening a closed workstream no longer overwrites the model alias and per-workstream config with session defaults.
  • Console home composer: attachments + user-message pills — multipart attachments in the home composer were not forwarded correctly; user-message pills in the coordinator chat pane were missing.

[1.5.5]

Fixed

  • Saved-workstream tool result rendering — tool results in closed workstreams were not rendering on history replay. Audit-trail decoration for tool calls is now applied on the replay path.

[1.5.4]

Added

  • Stage 3 SessionManager Children primitive lift — child workstreams are first-class citizens in the cluster event bus. child_ws_state events are pushed through the cluster SSE stream so the console tree view updates in real time without polling. list_children and get_child primitives on SessionManager provide a consistent cross-node view of the coordinator's spawn tree.
  • Multi-select delete for Saved Coordinators — the Saved Coordinators grid in the console admin panel now supports checkbox multi-select with a bulk-delete action.

[1.5.3]

This release introduces one forward-only schema migration: 048_workstream_reaper_index — partial composite index on workstreams for the orphan-reaper query.

Fixed

  • Coordinator orphan reaping scoped by heartbeat — the session manager's close_idle pass now scopes the DB-orphan reaper by services.last_heartbeat so workstreams belonging to a live node are not incorrectly reaped. bulk_close_stale_orphans and touch_workstream storage primitives added; a partial composite index keeps the reaper scan cheap.
  • Coordinator pool idle cleanup — a periodic task on the console now closes coordinator pool entries whose session has gone idle past the configurable threshold, preventing pool exhaustion on long-running consoles.

[1.5.2]

Added

  • Metacognition themed reminder bubble — repeat-tool and user-reminder nudges are rendered as a distinct styled bubble rather than being injected inline into the assistant message, making it easier to distinguish model output from metacognitive annotations. The CLI REPL gains matching on_user_reminder / on_tool_reminder callbacks.

Fixed

  • Metacog streak detector — the N≥3 sequential-same-call streak detector now fires correctly on the third repetition; a write-success-clear that reset the counter after a successful tool call (preventing streaks across mixed-outcome sequences) was removed.
  • Metacog reminders isolated to side-channel — reminder text no longer appears in the user content turn; it flows through a dedicated side-channel the session injects into the system context, preventing the model from attributing it to the user.

[1.5.1]

Added

  • pending_approval_detail on child ws_state SSE events — coordinators now receive the child's pending approval detail in child_ws_state events, enabling the coordinator to surface approval prompts without a separate poll.

Fixed

  • Coordinator registry auto-refresh — the console coordinator registry now refreshes when model definitions change, so a newly added alias is visible to coordinators without restarting.
  • Coordinator fan-out default — coordinators now fan out to independent child workstreams by default instead of serialising them, matching the documented contract for parallel-work patterns.
  • wait_for_workstream message cap raised to 10 KiB — large plan summaries and tool results from child workstreams were silently truncated at the previous 4 KiB cap.
  • Coordinator SSE isolated on dedicated thread pool — coordinator SSE polling now runs on a dedicated 200-thread executor, matching interactive's sse_executor, so coordinator long-poll blocking no longer contends with storage and routing workers on the default pool.

[1.5.0]

User-visible additions: a unified workstream HTTP surface (interactive and coordinator under one URL family), inline child approvals, coordinator composer parity, progressive rendering, OIDC authentication, MCP OAuth foundations, and a redesigned UI built on the Design System v1 token layer.

This release removes the pre-1.5 body-keyed and query-keyed URL family. See Removed (BREAKING) below before upgrading from a 1.x stable line.

This release introduces the following forward-only schema migrations that the server applies automatically on first startup. All are additive; no data loss.

  • 039_workstream_kindkind + parent_ws_id columns on workstreams.
  • 040_coord_cluster_admin_perms — grants admin.coordinator + admin.cluster.inspect to the builtin-admin role.
  • 041_workstream_index_tuning — refined indexes for the workstream query mix introduced by 039.
  • 042_coord_trust_send_perm — adds coordinator.trust.send permission to builtin-admin.
  • 043_skill_description_required — backfills empty description rows in prompt_templates.
  • 044_skill_kind — adds kind classifier column to prompt_templates (interactive / coordinator / any).
  • 045_skill_risk_level_rename — renames prompt_templates.scan_statusrisk_level.
  • 046_drop_hash_ring_tables — drops the hash-ring bucket tables superseded by rendezvous routing in 1.4.
  • 047_drop_coord_spawn_quota_settings — removes the spawn-quota settings rows removed from the coordinator in 1.5.0a4.

Added

  • Inline child approvals — pending tool approvals on coordinator child workstreams surface directly in the coordinator tree view. A risk pill shows the judge verdict (or "pending" while the judge evaluates); Approve/Deny buttons appear inline so operators do not need to navigate to the child's workstream. pending_approval_detail is exposed on GET /v1/api/dashboard and passed through the cluster live-bulk SSE payload so all connected clients render approval prompts simultaneously. LLM judge verdicts are cached client-side and replayed on SSE reconnect.
  • Coordinator composer parity — the coordinator composer now supports Stop, Send-to-queue, and Attach (file upload), matching the interactive workstream composer feature set.
  • Per-call model and judge override on coordinator composer — operators can override the model alias and judge model for a single coordinator send from the composer, without changing the node-wide or role-wide defaults. Bad aliases return a corrective error listing available choices.
  • Coordinator status bar + richer history replay — each coordinator workstream gains a per-coordinator status bar showing active children, token spend, and generation state. History replay in the coordinator panel is extended to include tool results and thinking blocks.
  • Coordinator child error surfacing + memory tool — child workstream errors are surfaced as distinct error rows in the coordinator tree view rather than disappearing silently. The coordinator gains access to a memory tool (same interface as interactive) for retrieving stored facts.
  • Coordinator inline tool-batch construct — the coordinator tool approval UI replaces the separate approval dock with an inline batch construct that groups all pending tool calls for a given turn into a single review card.
  • Node capability auto-detection — nodes report kernel-level capabilities (available memory, CPU count, accelerator presence) via /v1/api/node/capabilities at startup, enabling the console to filter model aliases offered to coordinators routing to that node.
  • Skills: paste SKILL.md to auto-fill the Create Skill modal — pasting a SKILL.md file's content into the modal auto-populates the name, description, and configuration fields.
  • Progressive mermaid rendering — Mermaid diagrams begin rendering as soon as a complete diagram block is detected in the stream rather than waiting for the full response; the diagram re-renders in place as the model extends it.
  • LaTeX and MathML delimiter support\(…\) inline and \[…\] block math delimiters are now recognised alongside the existing $$ fences.

Removed (BREAKING — 1.5.0)

  • Legacy body-keyed and query-keyed URL family for the workstream interaction verbs. Pre-1.5 interactive shipped both a path-keyed and a body-keyed surface for the same five verbs; this release drops the body-keyed and query-keyed mounts (and the make_legacy_body_keyed_adapter / make_legacy_query_keyed_adapter shims that backed them). External SDK consumers on stable 1.0/1.3/1.4 must move to the path-keyed shape:

    Removed (1.0/1.3/1.4) Use instead
    GET /v1/api/events?ws_id=X GET /v1/api/workstreams/{ws_id}/events
    POST /v1/api/send (body ws_id) POST /v1/api/workstreams/{ws_id}/send
    DELETE /v1/api/send (body ws_id) DELETE /v1/api/workstreams/{ws_id}/send
    POST /v1/api/approve (body ws_id) POST /v1/api/workstreams/{ws_id}/approve
    POST /v1/api/cancel (body ws_id) POST /v1/api/workstreams/{ws_id}/cancel
    POST /v1/api/workstreams/close (body) POST /v1/api/workstreams/{ws_id}/close

    Calls to the old URLs return 404 on 1.5.0+. Bodies on the new URLs no longer carry ws_id (the path provides it); the SendRequest / ApproveRequest / CancelRequest Pydantic schemas drop the field, and CloseWorkstreamRequest slims to a single optional reason field (the body is still required to be valid JSON — send {} when omitting all fields).

    /v1/api/plan and /v1/api/command are unaffected and remain body-keyed in this release. The bundled web UI, channel adapters, Python SDK, TypeScript SDK, and console routing-proxy SDK ship the new URLs automatically; pinning to ≥ 1.5.0 is enough.

    The console routing proxy's /v1/api/route/... family is updated alongside: /v1/api/route/workstreams/{ws_id}/<verb> replaces the pre-1.5 /v1/api/route/{send,approve,cancel,workstreams/close} mounts. DELETE is now passed through (client.request(method, ...) instead of client.post(...)) so the new dequeue route works through the proxy. Audit attribution for DELETE on /send is logged as route.workstream.dequeue rather than route.workstream.send.

    Auth scope wiring (WRITE_PATHS / APPROVE_PATHS literals plus the path-keyed verb match in required_scope) updated to grant write for path-keyed send/cancel/close, approve for path-keyed approve, and write for DELETE on path-keyed /send. The /node/* proxy branch mirrors all four.

Changed

  • Dashboard row shape: idws_id. The GET /v1/api/dashboard row dict now keys the workstream identifier as ws_id (matching the rest of the v1 workstream surface — active list, saved list, history, detail). The Stage 2 list-verb lift converged /v1/api/workstreams and /v1/api/workstreams/saved on ws_id but left dashboard alone to keep that PR's diff focused; this lands the same rename on the remaining endpoint so the v1 row shape is consistent across the family. Pydantic DashboardWorkstream and the TypeScript SDK DashboardWorkstream interface both rename the field accordingly. The bundled web UI is the only consumer that reads dashboard.workstreams[].id and is updated atomically; no external SDK on a stable line reads the field, so the swap is bounded by normal static-asset reload. Console _fetch_live_block (cluster-inspect's projection over a remote node's dashboard payload) is updated to match.

  • Coordinator gains rich ws_state payload + live activity broadcast ([§ Post-P3 reckoning item #2 follow-up]). Pre-lift coord's cluster broadcast was state-only — the dashboard's coord rows showed the state column flipping but the tokens, context_ratio, activity, and per-turn content fields were all hardcoded to zero / empty. The lift turns on_status / on_content_token / on_thinking_start / on_thinking_stop / on_stream_end / on_tool_result into shared bodies on :class:SessionUIBase so coord populates the same per-ws metric fields interactive does (the fields were already declared on the base; only the writes were WebUI-specific). coord_adapter.emit_state now reads the UI's snapshot under _ws_lock via the new :meth:SessionUIBase.snapshot_and_consume_state_payload helper and passes the rich kwargs through to collector.emit_console_ws_state; the cluster dashboard's coord rows now render with the same tokens / activity / content / context_ratio fields interactive rows do.

    Three observable behaviour changes (all CHANGELOG-callout-worthy):

    • Coord persists usage_event storage rows. Pre-lift only WebUI did. The lifted on_status body unifies usage tracking so governance dashboards / token-spend queries see coordinator consumption alongside interactive. Operators querying usage_event by ws_id will see coord rows for the first time.
    • Coord broadcasts live activity transitions. New ClusterCollector.update_console_ws_activity(ws_id, *, activity, activity_state) method (named update_* rather than emit_* to flag the no-fan-out asymmetry vs. the rest of the emit_console_ws_* family — it updates the in-memory pseudo-node row but intentionally does NOT fan out a separate SSE event). The cluster dashboard's per-ws polling reads the in-memory pseudo-node row, so activity ticks land on the next snapshot fetch (matches WebUI's behaviour where activity events are observational; not fanned out through the cluster SSE stream).
    • Cluster cluster_state events for coord rows now carry non-zero tokens / content fields. Frontend rendering that conditionally hid these on coord rows can drop the branch.

    Architecture changes:

    • _MAX_TURN_CONTENT_CHARS moved from turnstone.server to turnstone.core.session_ui_base so coord enforces the same per-turn content cap interactive does.
    • WebUI keeps on_status / on_tool_result / on_error overrides that layer Prometheus _metrics.record_* calls (node-only) on top of the shared body via super() — the Prometheus surface stays node-scoped (the console isn't a node and has no /metrics endpoint).
    • ConsoleCoordinatorUI adds a _broadcast_activity override that fans out via the cluster collector instead of the global SSE queue (which is node-only on interactive).
    • coord_endpoint_config wires a new _coord_spawn_metrics hook (mirrors interactive's) so the per-spawn _ws_messages increment + _ws_turn_tool_calls reset happen on coord too.

    Test additions: 23 new tests in tests/test_coord_rich_ws_state_payload.py pin the per-ws metric writes (status, content accumulation, activity tracking, tool-result counters, stream-end activity clear), the snapshot helper's IDLE/ERROR drain semantics + single-lock-acquisition guarantee, the adapter's rich-payload pass-through + defensive None-UI handling, the activity broadcast (collector wire + failure swallow + no-op-when- collector-unset + dedup against last-emitted state), the spawn_metrics hook, and a concurrent-writes-during-snapshot stress case (cycles through running / idle / error so the drain branches actually run against a concurrent writer). Plus WebUI-override regression tests confirming _metrics.record_* still fires on top of the lifted bodies. Existing tests/test_webui_content.py updated to import _MAX_TURN_CONTENT_CHARS from its new home in turnstone.core.session_ui_base; tests/test_coordinator_adapter.py updated to expect the rich-payload kwargs (tokens=0 defaults) on emit_console_ws_state.

    Two deferred follow-ups (out-of-scope for this lift, flagged for tracking):

    • Synchronous record_usage_event INSERT on coord worker thread. The lifted on_status body persists usage rows on every provider response — same shape WebUI uses, but coord workers can fire multi-step plan/task agent loops where each response blocks the worker for a write transaction. Parity with WebUI is the explicit goal here; if coord throughput becomes a concern, batch usage_event writes onto a background flusher thread (one batch INSERT per N events / per K ms) on both kinds.
    • Coord assistant turn content now flows on the cluster SSE stream (/v1/api/cluster/events). Pre-lift the broadcast was content=""; post-lift it carries the joined assistant output. The cluster SSE stream has no per-user filter today — extends an existing cross-tenant exposure (interactive cluster_state events already carry content) to a previously-empty channel (coord rows). Proper fix needs the SSE endpoint gated on admin.cluster.inspect (matching /v1/api/cluster/ws/{ws_id}/detail) or per-listener user_id filtering. Tracked as a separate security-tightening project; not gating this lift since it inherits an existing exposure rather than introducing a new mechanism.
  • history / detail verb bodies lifted across both kinds ([Stage 2 Verb Lift — history / detail]). The coord GET /v1/api/workstreams/{ws_id}/history and GET /v1/api/workstreams/{ws_id} handlers now share two factory bodies via make_history_handler(cfg) and make_detail_handler(cfg). The lift adds both endpoints to the interactive surface as a feature gain (pre-lift only coord exposed them; interactive consumers had to subscribe to /events SSE just to read history rows or display fields). No new SessionEndpointConfig fields — the factories reuse permission_gate, manager_lookup, not_found_label, audit_action_prefix, and (for history's storage-fallback kind check) list_kind — all already wired by both production lifespans.

    Three observable behaviour changes (all documented per kind):

    • Interactive gains GET /v1/api/workstreams/{ws_id}. Pre-lift interactive had no detail endpoint — SDK consumers had to read display fields from the SSE replay on /events or scrape the active list. The lifted body lazy-rehydrates a closed/evicted workstream via mgr.open() so the response shape is stable across loaded / persisted-only states. Same {ws_id, name, state, user_id, kind} shape coord exposed pre-lift, now available on both surfaces.
    • Interactive gains GET /v1/api/workstreams/{ws_id}/history. Same ?limit= query param contract as coord (default 100, max 500, malformed values fall back to 100, out-of-range clamps to [1, 500]). Persisted-but-not-loaded interactives serve history without rehydrating — the lifted body falls back to a storage-row
      • kind check (via cfg.list_kind) when mgr.get returns None, mirroring coord's pre-lift _resolve_coordinator_or_404 ladder.
    • Storage / manager-lock work moved off the event loop on coord. The lifted history body always runs storage.get_workstream (storage-fallback path) and storage.load_messages through asyncio.to_thread; pre-lift coord ran them inline on the event loop. Long-tail message reads on a saturated console no longer stall every other async handler for the duration of the SQL.

    Pydantic schemas: CoordinatorDetailResponse and CoordinatorHistoryResponse removed; both folded into WorkstreamDetailResponse / WorkstreamHistoryResponse on the shared server_schemas.py (mirrors the list lift's pattern for WorkstreamInfo). Both server and console OpenAPI specs reference the unified schemas; server_spec.py gains EndpointSpec entries for the new interactive endpoints. TS SDK gains WorkstreamDetailResponse / WorkstreamHistoryResponse interfaces in sdk/typescript/src/types.ts; openapi-{server,console}.json regenerated. GET /v1/api/workstreams/{ws_id}/history is the only verb whose lifted body keeps a kind-aware storage fallback (via cfg.list_kind); detail defers cross-kind isolation to mgr.open() itself.

  • list / saved verb bodies lifted across both kinds ([Stage 2 Verb Lift — list / saved]). The interactive GET /v1/api/workstreams + GET /v1/api/workstreams/saved and coord GET /v1/api/workstreams + GET /v1/api/workstreams/saved handlers now share two factory bodies via make_list_handler(cfg) and make_saved_handler(cfg). Four new SessionEndpointConfig fields capture the per-kind divergence:

    • list_resolve_titles: ListResolveTitles | None — interactive wires :func:turnstone.core.memory.get_workstream_display_names (new bulk helper added on the storage layer + memory.py) so the active-list endpoint resolves every user-set alias in ONE SELECT ... WHERE ws_id IN (...) instead of the pre-lift per-row N+1. Coord wires None (no alias surface today).
    • list_kind: WorkstreamKind | None — required storage-side kind classifier passed to list_workstreams_with_history. Interactive wires WorkstreamKind.INTERACTIVE; coord wires WorkstreamKind.COORDINATOR. Distinct from audit_action_prefix (audit-action namespacing) so adding a third kind doesn't have to overload the audit prefix as a classifier; missing value surfaces as 500 with a clear log line rather than silently filtering for the wrong kind.
    • saved_state_filter: str | None — coord wires "closed" so only explicitly-closed coordinators surface in the saved-card grid. Interactive wires None (the storage layer already excludes state='deleted' tombstones).
    • saved_loaded_lookup: SavedLoadedLookup | None — coord-only defence-in-depth filter that excludes ws_ids currently in the in-memory pool (a row can be state='closed' for a few seconds while the close-emit sequence races the in-memory pop). Interactive wires None.

    Five observable behaviour changes (all documented per kind):

    • Active-list top-level key converges on "workstreams". Pre-lift coord returned {"coordinators": [...]}; the lifted body returns {"workstreams": [...]} for response-shape parity with interactive. Coord is a 1.5.0aN-only surface — never shipped stable — so SDK / frontend consumers swap once and there's no compat shim or fallback (the convergence MUST land before v1.5.0 stable per project_unification_before_stable.md).
    • Saved-list top-level key converges on "workstreams". Same shape change as the active list, applied to GET /v1/api/workstreams/saved on coord. Coord-only surface; no compat shim.
    • Active-list row key renames "id""ws_id" on interactive. Pre-lift interactive used the bare id field while every other shared verb on this surface (cancel, open, events, create, saved-list) uses ws_id. Convergence eliminates the internal inconsistency. Frontend consumers reading ws.id from the active-list response swap to ws.ws_id. Interactive HAS shipped stable across 1.0 / 1.3 / 1.4, but the active-list endpoint is consumed by the bundled JS only — there's no external SDK on those stable lines reading the field. Browser-cache staleness is bounded by normal static-asset reload on next page load.
    • Active-list row gains always-include fields. user_id was coord-only; kind + parent_ws_id were interactive-only. Both kinds now populate all three. parent_ws_id defaults to None for coord (coordinators have no parent).
    • Storage / manager-lock work moved off the event loop on interactive. The lifted saved body always uses asyncio.to_thread for list_workstreams_with_history; pre-lift interactive ran it inline (correlated COUNT subquery can stall every other async handler on a cluster with thousands of saved rows). Coord already used to_thread (perf-2 from the saved-coordinators review); convergence lifts interactive up. The active-list body also moves mgr.list_all + per-row title resolution off the event loop on both kinds.

    Pydantic schemas: WorkstreamInfo.id renamed → ws_id, WorkstreamInfo.user_id field added. CoordinatorInfo and CoordinatorListResponse removed (folded into the unified WorkstreamInfo / ListWorkstreamsResponse); console_spec active-list endpoint now points at ListWorkstreamsResponse. OpenAPI spec snapshots regenerated.

    GET /v1/api/dashboard is not in the lift's scope and still returns rows keyed on id. A separate cleanup PR will converge the dashboard row shape with the rest of the v1 surface.

  • SessionManager.create gains a deferred-emit option; lifted create HTTP handler eliminates the phantom create→close pair on coord rollback. SessionManager.create now accepts defer_emit_created: bool = False (default preserves the legacy "advertise immediately" contract for direct callers); two new methods complete the deferred-create bracket:

    • SessionManager.commit_create(ws) fires the deferred emit_created event after the caller's post-create work confirms the workstream should be advertised.
    • SessionManager.discard(ws_id) releases the in-memory slot
      • cleans up the UI WITHOUT firing emit_closed — the workstream's existence was never advertised, so there's nothing to advertise on rollback. Storage-row deletion stays a separate concern (caller invokes delete_workstream for a complete rollback), mirroring mgr.create's split between slot reservation and register_workstream. Logs a warning (session_mgr.discard.after_emit_created) when invoked on a workstream that's already been advertised (non-deferred create or post-commit_create); the slot is still released so capacity isn't stranded, but the warning surfaces the caller-bug case where close would have been the right call.

    The lifted make_create_handler now uses this bracket: pass defer_emit_created=True, validate uploaded attachments, then mgr.commit_create(ws) on success / mgr.discard(ws.id) on failure. Pre-fix, coord's mgr.create fired emit_created synchronously — a rollback then called mgr.close which fired emit_closed, surfacing a quick create→close pair on the cluster events stream that the collector's diff-reconcile had to handle. Post-fix, a rejected upload produces zero events. Interactive's emit_created is a documented no-op stub so the deferral is observably a no-op there; the ws_created broadcast on the global SSE queue continues to fire from the kind's post_install callback after attachment validation passes (unchanged).

    Direct callers of mgr.create (test fixtures, the CLI REPL, channel adapters) keep the default defer_emit_created=False and see no behaviour change.

  • Coordinator HTTP surface unified under /v1/api/workstreams/ ([Stage 2 Priority 0]). The experimental /v1/api/coordinator/* URL tree from 1.5.0aN is removed; coord verbs now mount at the same shape as interactive workstreams via a shared route registrar (turnstone.core.session_routes). Path mapping:

    Was (1.5.0aN) Now
    POST /v1/api/coordinator/new POST /v1/api/workstreams/new
    GET /v1/api/coordinator GET /v1/api/workstreams
    GET /v1/api/coordinator/saved GET /v1/api/workstreams/saved
    GET /v1/api/coordinator/{ws_id} GET /v1/api/workstreams/{ws_id}
    POST /v1/api/coordinator/{ws_id}/{verb} POST /v1/api/workstreams/{ws_id}/{verb}

    Permission scopes, request / response bodies, and SSE event shapes are unchanged. Callers on the experimental 1.5.0aN coord SDK must swap their URL prefix; the legacy paths are gone with no compat shim. Stable releases (1.0 / 1.3 / 1.4) never exposed /v1/api/coordinator/, so this change is a no-op for anyone upgrading from a stable line.

    Two handler bodies (approve, close) lifted into the shared registrar with kind branching behind SessionEndpointConfig — both kinds share one implementation per verb. Two related behavior changes on the interactive close path:

    • mgr.close() race-loss returns 404 (was 500 on coord; "popped between .get() and .close()" is a not-found semantic, not a server error).
    • Audit-write failures (record_audit raising on the storage write) are now caught and logged at warning level; the close still returns 200. Previously the interactive path let the exception propagate as HTTP 500. Coord previously already swallowed; convergence is intentional — operators monitor the ws.close.audit_failed log line in both kinds the same way.

    Other shared verbs (send, cancel, open, events, create, list, saved, history, detail) keep their per-kind handlers — body convergence for those requires SessionManager- side refactors (e.g. Priority 1's worker-dispatch unification for send) or coordinated frontend changes (response-shape unification for list / saved) that fall outside Priority 0 scope.

  • TypeScript SDK bumped to 0.4.0 to flag the URL change for any 1.5.0aN-era consumer of the experimental coord client. The openapi-{server,console}.json reference specs ship with the unified path tree.

  • Worker dispatch unified across interactive + coordinator ([Stage 2 Priority 1]). The atomic check-and-(spawn-or-queue) decision for ChatSession.send now lives in turnstone.core.session_worker.send and is shared by both paths. Interactive /v1/api/send, the coordinator adapter, the watch-result dispatch, the rewind/retry path, and the initial-message-on-create path all gate on Workstream._worker_running (set/cleared atomically under ws._lock) instead of Thread.is_alive() — closes a race where two senders could spawn parallel workers on the same ChatSession.

    The /send HTTP body itself stays per-kind in this PR. Verb-shape convergence (one shared factory body with capability flags for attachments / queue priorities / metric increments) is tracked as P1.5 and MUST land before 1.5.0 stable — letting the fork ship into the stable line bakes the duplication in for the lifetime of the 1.5 track.

  • /send body lift + coordinator attachments + queue surface parity ([Stage 2 Priority 1.5]). The /send HTTP handler is now ONE factory body (make_send_handler(cfg)) wired with capability flags on both kinds; the four attachment endpoints (upload / list / get_content / delete) are also unified via make_attachment_handlers(cfg). Coord workstreams light up:

    • POST/GET /v1/api/workstreams/{ws_id}/attachments, GET .../attachments/{aid}/content, DELETE .../attachments/{aid} — same shape, same caps, same reservation flow as interactive.
    • POST /v1/api/workstreams/{ws_id}/send accepts attachment_ids (or auto-consumes pending) and returns attached_ids / dropped_attachment_ids for surfacing partial reservations. Live-worker reuse path also returns priority / msg_id (parity with the interactive status: queued shape).

    Backend parity is end-to-end: storage layer was already kind-agnostic; the route registrar's AttachmentHandlers slot has been there since Stage 2 P0; the multi-node attachment routing-proxy on the console (route_attachment_proxy) was already shipping. P1.5 is the wiring + verb-shape lift that lets these primitives surface on the coord side.

    Coord dashboard rendering surfaces an attachment-count badge on past messages with attachments; full chip rendering with click-to-view is deferred (the coord dashboard is diagnostic-leaning and chip parity isn't on the critical path for the unification thesis). Python SDK adds coordinator_send / coordinator_upload_attachment / coordinator_list_attachments / coordinator_get_attachment_content / coordinator_delete_attachment on AsyncTurnstoneConsole + TurnstoneConsole. TS SDK regenerated; bumped to 0.5.0.

    Three lifted helpers (sniff_image_mime, classify_text_attachment, upload_lock) moved from turnstone/server.py to turnstone/core/attachments.py so both processes use the canonical implementation. The interactive surface keeps the same behaviour; the helpers are simply imported from their new home.

    coordinator_send no longer returns 429 on a full worker queue — the unified body returns 200 {"status": "queue_full"} for parity with interactive. Existing callers checking for 429 should switch to the status-code shape.

    Coord GenerationCancelled now emits state=idle + stream_end (parity with interactive); pre-P1.5 a cancel-killed coord worker would have terminated silently with no state event. Cluster fanout / alerting keyed on state=error for cancelled coord workers should switch to monitoring stream_end / state=idle together.

  • SessionKindAdapter Protocol split into construction + emission ([Stage 2 Priority 3]). The adapter Protocol now covers only what every kind must implement (kind / build_ui / build_session / cleanup_ui); the four lifecycle emit methods (emit_created / emit_state / emit_rehydrated / emit_closed) move to a separate SessionEventEmitter Protocol wired through a new optional event_emitter: SessionEventEmitter | None kwarg on SessionManager. Both production adapters (interactive on server.py, coordinator on console/server.py) implement both Protocols and are passed as both adapter and event_emitter at lifespan-construction time, so production behavior is unchanged. The interactive adapter's three emit_created / emit_state / emit_rehydrated methods remain documented no-op stubs (those events fire from out-of-band paths — the create handler enqueues ws_created after attachment validation, WebUI._broadcast_state emits ws_state); emit_closed stays load-bearing as the sole transport path for ws_closed onto the global SSE queue.

  • cancel verb body lifted across both kinds ([Stage 2 Verb Lift — cancel]). The interactive /v1/api/cancel and coord /v1/api/workstreams/{ws_id}/cancel handlers now share one body via make_cancel_handler(cfg, *, audit_emit=None); per-kind divergence captured by a new cancel_forensics: CancelForensics | None field on SessionEndpointConfig (interactive wires _capture_cancel_forensics; coord wires None). Three observable behaviour changes for coord callers:

    • Coord cancel now accepts a force flag. Same shape as interactive: posting {"force": true} abandons the worker thread and emits stream_end so a stuck coord generation can be recovered without waiting for the daemon thread to exit. Pre-lift coord ignored force.
    • Coord cancel response always includes "dropped". Pre-lift coord returned bare {"status": "ok"}; the lifted body returns {"status": "ok", "dropped": {}} (always-include parity with interactive). SDK consumers don't need to branch on kind to read dropped.
    • Coord cancel returns 400 when the workstream's session is None. Pre-lift coord called coord_mgr.cancel which silently no-op'd on a placeholder/build-failed workstream; the lifted body 400s with {"error": "No session"} for parity with interactive's pre-existing branch.

    Two observable changes for interactive (asymmetric — coord pre-lift already had this behaviour):

    • resolve_plan now runs on every cancel (previously gated on was_running). resolve_plan has an internal _pending_plan_review is None guard, so the call is no-op when no plan review is pending. Lift gives interactive coord's pre-lift recovery path: a stuck plan-pending state from a crashed worker can be cleared via cancel instead of requiring a workstream close + rehydrate.
    • resolve_approval runs on every cancel only when ui._pending_approval is not None (the lifted body gates the call). resolve_approval is not idempotent — it always broadcasts approval_resolved and overwrites _approval_result — so the gate prevents a stale resolution event from leaking on idle cancels while preserving the recovery path when an approval really is pending.

    Coord coordinator.cancel audit detail now includes force so operator-driven recovery is distinguishable from a routine cancel in the audit log.

    Three /review fixes folded into the same commit:

    • No more stale approval_resolved SSE event on idle cancel. The lifted body's resolve_approval call is now gated on ui._pending_approval is not None. Pre-fix, the unconditional call would broadcast a phantom approval_resolved to every SSE listener even when no prompt was pending — listener UIs that key on the event would dismiss prompts they didn't have.
    • Force-cancel now clears _worker_running alongside worker_thread. Previously the force path left the half- state (_worker_running=True, worker_thread=None), which routed any follow-up send through the queue-enqueue path onto the abandoned worker (where the cancel flag short-circuits the queue-drain seam, leaving the message orphaned until the next spawn). Restores the (worker_thread, _worker_running) invariant session_worker.send documents.
    • coordinator_stop_cascade now treats child cancel 400 + "No session" as skipped (was previously failed). Lifted coord cancel returns 400 on placeholder / build-failed children — matching the pre-lift outcome where those children were silently no-op'd, so the cascade response's failed bucket no longer fires spurious operator alerts.
  • open verb body lifted across both kinds ([Stage 2 Verb Lift — open]). The interactive POST /v1/api/workstreams/{ws_id}/open and coord POST /v1/api/workstreams/{ws_id}/open handlers now share one body via make_open_handler(cfg, *, audit_emit=None). Per-kind divergence captured by two new SessionEndpointConfig fields:

    • open_resolve_alias: AliasResolver | None — interactive wires :func:turnstone.core.memory.resolve_workstream so callers can pass user-friendly aliases ("my-debug-ws") in the path param. Coord wires None (hex ids only).
    • open_post_load: OpenPostLoad | None — interactive wires the UI-replay (clear_ui + history) + handler-side ws_created enqueue onto the global SSE queue. Coord wires None and relies on the cluster collector fan-out from CoordinatorAdapter.emit_rehydrated.

    Load-bearing fix (§ Post-P3 reckoning item #3): interactive open_workstream previously called mgr.create(ws_id=resolved_id) + ws.session.resume(...) to rehydrate, bypassing mgr.open() entirely. After the lift both kinds route through mgr.open() — which makes InteractiveAdapter.emit_rehydrated reachable on interactive (it had been dead-by-routing) and gives the manager a single rehydrate code path to maintain. emit_rehydrated stays a documented no-op stub on the interactive adapter (the handler-side ws_created enqueue from open_post_load is the load-bearing emission).

    Two observable behaviour changes for interactive callers:

    • Cross-kind open returns 404 (was 400). Pre-lift had a pre-mgr storage probe that returned 400 with "Workstream is not an interactive kind" for coord rows; the lift consolidates on mgr.open()'s single None- return contract for missing / wrong-kind / tombstoned rows. Security boundary unchanged.
    • Already-loaded response uses ws.name directly (was get_workstream_display_name(resolved_id) or resolved_id). A workstream renamed via set_workstream_alias after being loaded into memory will surface the storage-row name in the open response's name field instead of the latest alias. The dashboard listing endpoint still resolves aliases on its own pass, so the user-visible workstream name in the tab strip isn't affected.

    Coord behaviour unchanged.

    Two /review fixes folded into the same commit:

    • Resume failures now return 5xx instead of broken-200. SessionManager.open() previously caught and log.debug- swallowed exceptions from ChatSession.resume (which assigns self.messages before the config-restore block, so a partial-failure resume — corrupted workstream_config row, model-registry mismatch on a saved alias, malformed temperature / max_tokens — would leave the session with history but with default config). Pre-lift, the interactive open handler called ws.session.resume(...) directly and let exceptions propagate as 500. The lift accidentally inherited the swallow because it routed through mgr.open(). Restored pre-lift behaviour: mgr.open() now re-raises resume exceptions after rolling back the slot (cleanup_ui + _remove_locked), so the lifted handler returns 500 with a correlation id and the storage row stays available for a retry instead of silently 200'ing with broken state.
    • except Exception in the lifted body documents intent. The bare exception catch around mgr.open(ws_id) is intentional — the kind's session factory has no documented exception spec, and resume can propagate from ChatSession.resume. A one-line rationale comment in the handler body keeps a future contributor from narrowing it incorrectly.
  • events verb body lifted across both kinds ([Stage 2 Verb Lift — events]). The interactive GET /v1/api/events?ws_id=... and coord GET /v1/api/workstreams/{ws_id}/events SSE handlers now share one body via make_events_handler(cfg). Per-kind divergence captured by a new events_replay: EventsReplay | None cfg field — a Protocol- typed callback yielding the kind-specific initial replay payload that the lifted body iterates and sends as data: lines before starting the live event loop. Interactive's _interactive_events_replay yields the pre-lift sequence (connected + status + history + pending_approval

    • cached intent verdicts + pending_plan_review); coord's _coord_events_replay yields just pending_approval + pending_plan_review (matches pre-lift coord behaviour).

    The legacy interactive query-keyed URL is preserved via a new make_legacy_query_keyed_adapter helper (sister to make_legacy_body_keyed_adapter from earlier lifts) — it reads ws_id from the query string and splices into request.path_params before delegating to the lifted body. GET /v1/api/events?ws_id=... continues to work for any 1.x SDK consumer.

    Two convergence wins:

    • Coord gains SSE connect/disconnect metrics. Pre-lift coord didn't record per-stream metrics; the lifted body always calls metrics.record_sse_connect() / ...disconnect(), giving the cluster dashboard the same per-stream observability interactive's had since 1.0.
    • Both kinds now check request.is_disconnected() AND the ws_closed event to terminate. Pre-lift interactive relied solely on ws_closed (which never fires if the client just goes away without closing the workstream); pre-lift coord relied solely on is_disconnected. The lifted body uses both — whichever fires first wins.

    One observable shape change for coord callers: the lifted body returns 409 "session has no UI" when ws.ui is missing (placeholder / build-failed UI), matching pre-lift coord. Pre-lift interactive returned 404 in this case; the lift converges on 409 across kinds because the workstream EXISTS (404 would imply it doesn't).

    Item #2 from § Post-P3 reckoning split out of this lift during scoping (rich ws_state payload parity for coord — lifting coord's ConsoleCoordinatorUI to broadcast tokens + context_ratio + activity + content like WebUI._broadcast_state does). The body lift touches session_routes.py + server.py + console/server.py; the rich-payload work touches coordinator_ui.py + collector.py + session_ui_base.py (different files, different reviewer concern). Tracked as standalone follow-up feat/coord-rich-ws-state-payload.

    Two /review fixes folded into the same commit:

    • Restored interactive's dedicated SSE thread pool. The initial draft of make_events_handler used asyncio.to_thread (default executor, capped at min(32, cpu_count + 4)) for the per-connection client_queue.get blocking wait. Pre-lift interactive used a dedicated 200-thread sse_executor (created in the lifespan with thread_name_prefix="sse") precisely to avoid this — under high concurrent SSE counts the default pool starves and SSE polling contends with every other asyncio.to_thread caller in the process (storage, router, audit). Restored isolation via a new sse_executor_lookup: SseExecutorLookup | None cfg field; interactive returns request.app.state.sse_executor, coord wires None and falls through to the default executor.
    • Restored 5s queue.get poll (was shortened to 1s in the initial draft). The 5x wakeup-rate bump compounded the thread- pool starvation; the request.is_disconnected() probe between polls already covers cancel-detection latency the timeout would otherwise gate.
    • Replay phase streams events directly from the generator instead of pre-building into a list. The initial draft materialised the entire kind-specific replay payload (connected + status + history + pending prompts) into a list before constructing the EventSourceResponse, delaying time-to-first-byte until the heaviest replay event (_build_history for long-running interactive workstreams) finished serialising AND letting the per-UI listener queue accumulate over its 500-slot cap on a chatty mid-generation workstream. The lifted body now iterates cfg.events_replay inside the async generator so each event ships as soon as the callback yields it; the existing observational-failure swallow semantics are preserved by wrapping the iteration in the same try/except.
  • create verb body lifted across both kinds ([Stage 2 Verb Lift — create]). The interactive POST /v1/api/workstreams/new and coord POST /v1/api/workstreams/new handlers now share one body via make_create_handler(cfg, *, audit_emit=None). Per-kind divergence captured by five new SessionEndpointConfig fields:

    • create_supports_attachments: bool — multipart body parsing
      • attachment validation+save+rollback. Both kinds wire True.
    • create_supports_user_id_override: bool — trusted-source body user_id override (interactive True for console- proxied creates; coord False).
    • create_validate_request: CreateRequestValidator | None — per-kind pre-create gates (interactive: ws_id format, kind, parent ownership, attachments+resume_ws combo; coord: 401-on- empty-uid).
    • create_build_kwargs: CreateKwargsBuilder | None — per-kind kwargs dict for mgr.create.
    • create_post_install: CreatePostInstall | None — per-kind tail end (interactive: WebUI auto_approve + watch_runner + ws_created global broadcast + atomic resume + skill session config + notify_targets + routing override + initial-message worker thread; coord: coord_adapter.send for the optional initial_message).

    The pure helper _validate_and_save_uploaded_files lifted from turnstone.server to turnstone.core.attachments as validate_and_save_uploaded_files so both processes can call the same kind-agnostic implementation.

    § Post-P3 reckoning item #1 done — coord gains create-time attachments. Pre-lift coordinator_create accepted JSON only and ignored uploads; the lifted body parses multipart/form-data on coord and saves attachments through the kind-agnostic storage layer. CoordinatorAdapter.send gained optional attachments + send_id kwargs so when a create request carries both initial_message and uploads, the attachments are reserved onto the dispatched first turn — the worker's ChatSession.send(..., send_id=...) consumes them on dequeue exactly the way interactive's create-with-attachments worker thread does. The send_id reservation token soft-locks the rows, and the adapter's failure path unreserves so a worker crash returns them to pending. The pure helper _reserve_and_resolve_attachments lifted from server.py to turnstone.core.attachments as reserve_and_resolve_attachments so both kinds call one kind-agnostic implementation.

    Note on broadcast timing: coord's mgr.create fires emit_created (cluster collector fan-out) BEFORE the lifted body runs attachment validation. If validation fails on coord and the rollback (mgr.closeemit_closed) fires, the cluster events stream sees a phantom create→close pair. Cluster consumers handle this gracefully (same shape as any quick-create-close); decoupling emit_created from mgr.create would be a bigger refactor that doesn't belong in the verb lift. Interactive's broadcast (gq.put_nowait("ws_created")) is held until after attachment validation by the post-install callback, so interactive never sees the phantom pair.

    Five observable behaviour changes on the create response:

    • Both kinds converge on 200 OK. Pre-lift interactive returned 200 (default JSONResponse status); pre-lift coord returned 201. Picked 200 over 201 for response-shape parity with every other shared verb at the cost of REST-strict correctness — a one-time release note rather than ongoing client churn (the rest of the v1 SDK already uses response.ok per feedback_test_frontend_locally.md). SDK consumers that branched on status == 201 for coord must switch to response.ok.
    • Always-include response shape. Pre-lift interactive returned {ws_id, name, resumed, message_count, attachment_ids} (5 fields); pre-lift coord returned {ws_id, name} (2). The lifted body always returns the full shape, with resumed=False / message_count=0 / attachment_ids=[] on kinds whose post-install doesn't populate them. Coord callers will see the parity fields appear with default values.
    • Both kinds converge on the manager-at-capacity 429 semantic. Pre-lift interactive translated mgr.create's RuntimeError to 400; coord already translated to 429. The documented contract on SessionManager.create is "raises RuntimeError when the manager is at capacity" — 429 (rate- limit / try-later) is the correct shape.
    • Both kinds converge on the factory-misconfig 503 semantic. Pre-lift interactive let ValueError propagate as 500 with a stack trace; coord already translated to 503 with the factory's remediation text. Operators get the actionable message instead of the trace.
    • Both kinds get a correlation_id'd 500 on unexpected mgr.create failure. Pre-lift interactive let unexpected exceptions propagate as 500 with a stack trace (potential information leak via frame names / file paths); coord already returned a correlation_id'd 500 with the message redacted. The lifted body adopts coord's safer pattern on both kinds.

    Two coord-specific parity gains:

    • Coord rejects disabled skills. Pre-lift coordinator_create silently allowed disabled skills to flow through to mgr.create — the row would create with a skill the operator had marked inert, surprising both the operator and the next user. The lifted body returns 400 "Skill not found or disabled" matching interactive's behaviour.
    • Coord audit-emit failures no longer 500. Pre-lift coordinator_create already swallowed; pre-lift interactive let the failure propagate as 500. The lifted body wraps audit_emit in try/except + warning log, returning the successful 200 to the caller. Mirrors the close / cancel / open / events lift contracts.

    No legacy adapter is needed for create — both kinds already mounted POST {prefix}/new pre-lift; the lifted handler slots in at the same path on each kind.

    Three /review fixes folded into the same commit:

    • Pre-lift's 400 on malformed notify_targets preserved. The initial draft surfaced notify_targets validation errors from inside the interactive post_install callback, which the factory had no return-the-400 channel for — the only signal was to raise, which the factory's generic exception handler turned into a redacted 500. Worse, by the time post_install ran the workstream was fully built (audit row written, ws_created broadcast emitted), so a malformed-input request surfaced as "create failed" with the workstream actually live. Fixed by moving the notify_targets validation into :func:_interactive_create_validate_request (the pre-create gate), which returns the 400 before mgr.create runs and keeps storage clean. New regression test: test_create_lift_400s_on_malformed_notify_targets.
    • Skill-lookup storage failure now correlation_id'd. The initial draft swallowed get_skill_by_name exceptions into skill_data = None and returned a 400 "Skill not found or disabled" — masking storage outages as user-input misses and making operator triage of skill-related reports impossible. The lifted body now lets the storage exception propagate to the same correlation_id'd 500 path that mgr.create failures use; the skill-lookup + version count + mgr.create all live inside one try / except so storage outages anywhere in the create-prelude get the redacted-message-with-correlation-id treatment instead of a stack-traced 500 leak.
    • Whitespace-only skill field treated as empty. The initial draft took body.get("skill") or "" literally — a payload with "skill": " " would have hit get_skill_by_name(" ") and 400'd as "Skill not found". Pre-lift coord stripped via (body.get("skill") or "").strip() or None; the lifted body now strips for both kinds (interactive never received whitespace-only skills from the web UI but the convergence is the safer default).
    • Canonical skill name persisted to mgr.create. The initial draft's _interactive_create_build_kwargs / _coord_create_build_kwargs passed the raw body["skill"] through, so a whitespace-padded request would have persisted " my-skill " even though the lookup was done on the stripped name. The build_kwargs callbacks now thread skill_data["name"] (the resolved row's canonical name) so the persisted Workstream.skill matches the row that was actually applied — keeps later session-side skill lookups working regardless of how dirty the inbound payload was.
  • Coordinator scratchpad tool renamed: task_listtasks. The tool name on the LLM-facing schema, the audit event name (task_list.updatetasks.update), the SSE tool_result event name (the coord-tree UI keys ev.name === "tasks" for /tasks-refetch debounce), and the log tag (task_list.corrupt_envelopetasks.corrupt_envelope) all switch together. Operators with audit dashboards / SIEM filters / log greps that pinned the old prefix should update; the rename is observable on the wire, not just internal. Internal Python surface follows: CoordinatorClient.task_list_*tasks_*, ChatSession._prepare_task_list / _exec_task_list_prepare_tasks / _exec_tasks, _TASK_LIST_MAX_TASKS_MAX. The previous name compounded the bare word task (which collides with chat-template channels on local models — the same reason task_agent carries the suffix); the plural form sidesteps the collision and is more accurate, since the tool acts on the whole list rather than a single task.

Security

  • Coord attachment endpoints are now kind-strict ([Stage 2 P1.5]). The coord attachment_owner_resolver resolves through the in-memory coord_mgr only — it does NOT fall back to storage. Without this, an admin.coordinator-scoped caller could pass an interactive workstream ws_id to the new coord attachment endpoints; the generic get_workstream_owner storage call (kind-agnostic) would resolve cleanly and grant cross-kind read / write access to interactive attachments. The kind-strict resolver returns 404 for any ws_id not currently held by the coord manager, closing the cross-kind path. Persisted-but-not-loaded coordinators must be opened before their attachment endpoints respond. Caught by /review pre-merge; no exploit observed.

  • Workstream state writes are now buffered through StateWriter. SessionManager.set_state no longer holds ws._lock across a synchronous Postgres UPDATE for non-terminal transitions; instead a StateWriter (constructed at app startup, started / shutdown by the lifespan) coalesces transient transitions per ws_id and flushes every ~1s. Observable behavior change: transient state (thinking / running / idle / attention) shows up in storage up to ~1s late; SSE consumers see it immediately via the adapter's emit_state. Terminal ERROR transitions and close() write synchronously and remain durable on return. The bug-3 invariant — a closed row can't be resurrected by a buffered transient — is preserved by close() calling state_writer.discard(ws_id) (drops pending + waits for any in-flight flush) before its sync state='closed' write.

User-visible additions: a full attachment system (images + text documents, including pre-creation uploads), a unified dashboard composer, a Slack channel adapter, per-call plan/task model selection with an admin UI, and provider capability passthrough.

This release introduces two forward-only schema migrations (037_workstream_attachments, 038_workstream_attachments_reserved_at) that the server applies automatically on first startup against an existing 1.3.x database. Both are additive; no data loss. See Database migrations below for details.

Added

  • Workstream attachments — images (png/jpeg/gif/webp, 4 MiB cap) and text documents (any text/* MIME, allowlisted application MIMEs, or known text extensions; 512 KiB cap; UTF-8 enforced). Magic-byte image sniffing on upload; per-(ws, user) pending cap of 10. Three-state lifecycle (pending → reserved → consumed) with reservation tokens threaded through /v1/api/send so queued multimodal turns can't lose files to overlapping sends. Provider-side translation: Anthropic emits native document blocks; OpenAI Chat Completions inlines them as escaped <document> text blocks; Responses API emits input_text with the same wrapper. (#356)
  • Attachments at workstream-creation timePOST /v1/api/workstreams/new accepts multipart/form-data (one meta JSON field plus 0..N file parts). Files are validated and reserved onto the first turn before the dispatch worker fires; failure rolls back the fresh workstream so no orphan rows leak. Web UI (new-workstream modal + dashboard composer), Python SDK, and TypeScript SDK all gained attachment support. Cluster routing (/v1/api/route/workstreams/{ws_id}/attachments) extended to forward multipart bodies + preserve upstream headers (CSP, Content-Disposition). SDKs auto-generate ws_id client-side so cluster-routed callers can bind the body to the owning node before it lands. (#362)
  • Slack channel adapter (Socket Mode) — mirrors the Discord adapter: per-user channel sessions via configurable slash command, DM routing without slash command, SSE event consumption, tool approval buttons with per-user owner enforcement, plan-review approve / request-changes modal, notification reply routing back into the workstream, and session recovery after restart via persisted recoverable route keys (the bot re-subscribes to existing Slack-routed workstreams when it comes back). Install with pip install 'turnstone[slack]'. (#355)
  • Console admin UX support for Slack — channel-link modal offers Slack alongside Discord; skill notify-on-complete forms expose a per-row channel-type dropdown (and no longer hardcode discord); per-platform .scope-discord / .scope-slack badge classes with theme-aware tokens (--discord / --slack) so light theme passes WCAG AA. (#365)
  • Per-call plan/task model selectionplan_model and task_model are now distinct from the conversation model and from each other, with configurable reasoning effort per agent. Three layers:
    • Backend split (#54dd557) — ModelRegistry gains plan_model, task_model, plan_effort, task_effort; per-kind overrides win over the legacy agent_model, which still works as the single-knob fallback. resolve_agent_alias(kind) and resolve_agent_effort(kind) centralise resolution. Loader validates effort against {none, minimal, low, medium, high, xhigh, max} with warn+drop on typos.
    • Runtime configurability (#360) — ConfigStore admin tab in the console UI lets operators switch alias and reasoning effort per agent without restarting. INHERIT_EMPTY_LABEL_KEYS shows (inherit) for empty effort selections — distinct from the literal none choice which actually disables reasoning. Routing overrides apply on /v1/api/_internal/config-reload (admin saves), and model-reload short-circuits when nothing changed so no in-flight clients churn.
    • Per-call override (#361) — the calling LLM can pass model="<alias>" to plan_agent or task_agent to override the operator-configured per-kind model for that one invocation. Tool descriptions list the live registered aliases (refreshed when the operator hits "sync to nodes"), so the LLM always sees current options. Bad aliases return a corrective error dict listing the available choices. No whitelist — cost control is intentionally ceded to the model. Plan-retry path reuses the alias so coaching reflects real model behaviour. (#360, #361)
  • Provider capability passthrough — resolved per-model capabilities (vision, reasoning, native web search, thinking_mode, token_param, etc.) flow through to provider clients via a new capabilities parameter on create_streaming / create_completion, so feature gating no longer relies on string matching and admin-UI / config.toml overrides actually reach the provider. Defensive shallow-copy in _finalize_extra_body so callers reusing the same dict across models are safe; deep-merge of chat_template_kwargs so operators can extend instead of silently overwriting. (#352)
  • Server compatibility layer for local model servers — vLLM and llama.cpp profiles suggest the right thinking mode and per-server workarounds (skip_special_tokens for vLLM, reasoning_format for llama.cpp) during model detection. Admin UI gains structured fields for server type, thinking mode, and extra body params, hidden for non-local providers (openai/anthropic/google). New thinking_param text field surfaces the alias name (default enable_thinking; Granite/DeepSeek use thinking). Verified end-to-end against real vLLM (Gemma 4 31B) and llama.cpp (Gemma 4 E4B) servers. (#352)
  • Claude Opus 4.7 supportclaude-opus-4-7 capability entry (1M ctx, 128K output, adaptive thinking, supports_temperature=False, thinking_display=summarized). New ModelCapabilities.thinking_display field — Opus 4.7 omits thinking by default but always sends summarized blocks back through the provider boundary. Adds xhigh effort level to the global mapping and to Opus 4.7's effort_levels; admin-console skill-template dropdowns gained xhigh and max options. Reasoning effort label capitalization aligned across all console dropdowns. (#357 — also in 1.3.1)
  • Dashboard composer refactor — unified single-flow create from the per-node dashboard. Multi-line textarea + collapsible Options panel (model / judge / skill) + paperclip + drag-drop / paste-image + chip strip. Submit-button label dynamically toggles between Create (empty) and Send (text or attachments staged); Enter and click both go through the same dashboardSubmit(). Replaces the inconsistent prior split where Enter created+sent raw and the button opened a separate modal. Options panel state persists in localStorage; active non-default selections render as an inline summary chip beside the Options button; drag-over shows an explicit "Drop to attach" overlay. The tab-bar + new-workstream modal also gained a paperclip
    • chip strip + first-message field so the same flow is reachable from both entry points. (#362, #366)
  • Workstream attachments — orphan reservation sweep — periodic background sweep clears reserved_for_msg_id on rows whose reserved_at exceeds a 1-hour threshold, self-healing reservations leaked by process crashes between reserve and consume. Backed by a partial index on (reserved_at) WHERE reserved_at IS NOT NULL so the scan stays cheap as the consumed-history grows. Threshold tracks reservation age, not upload age, so a long-pending fresh send can't be racially unreserved. (#363)
  • SendResponse extendedattached_ids, dropped_attachment_ids, priority, msg_id fields exposed in Pydantic + TypeScript SDKs so attachment-aware clients can detect partial reservations and dequeue queued messages. (#365)

Changed

  • plan_model and task_model now split from the conversation model and from each other — operators who rely on a single model for all three should set both plan_model and task_model explicitly in their config; otherwise both default to the conversation model so behaviour is unchanged. (#54dd557)
  • Channel notify-on-complete channel_type is no longer hardcoded in the admin UI — operators creating notify targets through the skill admin form previously got channel_type: "discord" regardless of what they wanted. Existing skill JSON values are unaffected; only newly created targets through the form differ. (#365)
  • Slack adapter approval previews — capped at 600 chars per item with a 2700-char total budget so multi-tool approval batches never exceed Slack's 3000-char section.text limit. Truncated batches show a …and N more (preview truncated) suffix. (#365)
  • PostgreSQL deployment image swapped from bitnami/pgbouncer to edoburu/pgbouncer to track upstream releases and reduce image size. Environment variables remapped to the edoburu naming, ports updated to match documented expectations, and the Kubernetes Helm Chart link in the deployment docs now points at the same container. Review your helm values if you depend on bitnami-specific environment variable conventions. (#353)

Fixed

  • plan_resolved SSE broadcast — when one client resolved a plan approval, other clients viewing the same workstream now have the approval card dismissed in sync. (#87a9af1)
  • Slack notification reply routing — one notification reply previously pinned every later assistant response for that workstream to the notification thread until the bot restarted. Reply-route override now clears on StreamEndEvent. (#365)
  • Slack plan-review mrkdwn fence — plan content containing triple backticks (very common — plans often quote code) no longer breaks the surrounding fence and lets later content render as live markup. The shared _sanitize_slack_preview helper splices a zero-width space inside any `` sequence while keeping single backticks readable. (#365)
  • Slack-routed workstreams now load the chat-specific system prompt via client_type="chat", matching Discord. (#365)
  • /v1/api/workstreams/new no longer emits a phantom ws_created/ws_closed SSE pair when attachment validation rejects a multipart create. Validation runs before the broadcast so failed creates are silent on dashboards. (#362)
  • Multipart Content-Type boundary preservation in console routing proxy — boundary= parameter is case-sensitive and was being lowercased before forwarding to the upstream node, breaking parsing for clients that used mixed-case boundaries (most browsers). (#362)
  • Local-theme contrast for new badge colors.scope-discord and .scope-slack first shipped with raw hex that failed WCAG AA on light theme (1.8:1 / 2.4:1). Theme-aware --discord / --slack tokens with proper light variants now pass. (#365)
  • Cross-user attachment fetch hardeningget_attachment_content now scopes the row by user_id in addition to ws_id, so an unowned workstream can't be a vector for cross-user blob fetches via attachment-id guessing. (#356)
  • Attachment-list DoS guard/v1/api/send rejects attachment_ids lists longer than the per-(ws, user) pending cap with a 400, preventing hostile clients from blowing up the storage IN (...) clause. (#356)
  • Bounded LRU for upload locks — the per-(ws, user) attachment upload-lock map now evicts the oldest unlocked entries past a soft cap, so the in-process map can't grow unbounded on long-running nodes. (#356)
  • 3.12 CI deadlock on attachment uploads — the upload-lock was initially an asyncio.Lock, but Starlette's TestClient runs each request on a fresh anyio task / event loop, so the cached lock's _waiters bound to the first loop and a later request would block on a Future from a closed loop (silent deadlock). Switched to threading.Lock — loop-agnostic, and the critical section is one COUNT + one INSERT. Same root cause is reproducible against any Starlette TestClient harness on Python ≥ 3.10; 3.12 surfaces it more often. Production users on a single event loop weren't affected, but the test environment was. (#356)

Security

  • Slack approval per-user authentication — only the session owner can click Approve/Deny on a Slack tool-approval card. Without this, any channel member with view access could approve dangerous tool calls initiated by someone else. (#355)
  • Attachment ownership masking — cross-user/cross-workstream attachment ID lookups return 404 (not 403) so non-owners can't enumerate workstream existence by response code. (#356)
  • Bumped Debian base image; remaining unfixable jq CVEs are documented and exception-listed. (#aaea4d3)

Database migrations

  • 037_workstream_attachments — new workstream_attachments table with the lifecycle columns described above. Indexes for ws_id, pending lookups, message linkage, and reservation scoping.
  • 038_workstream_attachments_reserved_at — adds reserved_at column for the orphan-sweep staleness signal, plus a partial index on reserved_at IS NOT NULL so the periodic scan is cheap.

Both migrations are additive and idempotent, and the server applies them automatically on first startup against an existing 1.3.x database. No manual alembic upgrade step is required — though running it manually beforehand (e.g. as part of a phased deploy) remains safe.

SDK

Python + TypeScript clients gained:

  • AttachmentUpload type
  • upload_attachment(ws_id, filename, data, mime_type=None)
  • list_attachments(ws_id)
  • get_attachment_content(ws_id, attachment_id) → bytes / Blob
  • delete_attachment(ws_id, attachment_id)
  • send(message, ws_id, attachment_ids=...) (extended)
  • create_workstream(..., attachments=[...]) — multipart variant with client-side ws_id generation for cluster-routed callers
  • Console SDK: route_create_workstream(attachments=...), route_upload_attachment, route_list_attachments, route_get_attachment_content, route_delete_attachment
  • Refusal of attachments + target_node combination at the SDK boundary (the multipart routing layer doesn't honor target_node, so silently picking the wrong node is now an explicit error)
  • PlanResolvedEvent SSE event with type guard, dispatched when one client (e.g. mobile) resolves a plan so other connected clients can dismiss their plan-approval modal in sync. Available in both the Python and TypeScript SDKs. (#87a9af1)

Operational

  • CI vendor-asset auto-download covers hls.js — the vendor-js.yml workflow previously only iterated katex/hljs/mermaid, so Renovate bumps for hls.js failed the wheel-completeness check and required manual file downloads. Detection loop now includes hls, so future Renovate bumps are merge-ready without intervention. (#354)

Contributors

Thanks to the people who made this release happen — especially the external contributors who picked up substantial pieces of work:

  • @daoxley — designed and shipped the Slack channel adapter (Socket Mode bot, per-user sessions, approvals, plan-review, notification routing). Major new feature surface in #355.
  • @pizzaandcheese — replaced the deprecated bitnami pgbouncer image with the edoburu image, remapped environment variables, ports, and helm chart references. Operationally important for anyone running our reference Postgres deployment (#353).
  • Renovate kept dependencies and the JS vendor tree current via several automated bumps.

If you're interested in contributing, channel-attachment ingest from Discord + Slack is the headline 1.4.1 feature and a solid place to start — see the open issues on GitHub or open one to scope a piece.

[1.3.1]
