The console OpenAPI spec had drifted from build_console_spec(): the committed
file was last generated at 1.7.0rc1 and was missing the persona and project_id
workstream-creation fields (Personas and Projects, both 1.7) plus the version
bump to 1.8.0a2. Regenerate via sdk/typescript/scripts/generate-types.py to
resync. Spec-only; no console API behavior change (openapi-server.json was
already current).
Eight rounds of findings against the defer-and-drain seam shared one
generator: N sites each hand-copying M obligations (spawn discipline,
the order-barrier pair, backpressure, best-effort emission, the client
settle matrix), with every review finding an empty (site x obligation)
cell. This round makes each obligation a single primitive:
- The order barrier is Workstream.send_barrier_active() — one
definition of the two-term pair (pending entries OR drain alive),
consulted by the /send route, the coordinator adapter, and the
queued-nudge wake gate, which previously carried only the list term
and let a synthetic wake jump an acknowledged send during the
claimed-entry window. _PendingSend moved to workstream.py beside the
invariant that justifies the drain-alive term; the pending fields got
precise types and worker_kind became a Literal, so a typo'd
"command" comparison is now a type error instead of a silently
never-firing defer guard.
- _defer_send probes the barrier before constructing anything, bounds
acceptance at 10 pending (the interjection queue's own backpressure
contract — unbounded acceptance pinned message + attachment bytes
per entry for a whole command window and then ran one unattended
turn each), and spawns the drain with rollback: a Thread.start
failure pops the just-accepted entry and answers the retryable
queue_full instead of 500ing after registration (a phantom the
client could neither see nor retract, dispatched later as duplicate
turns). start() deliberately stays inside the lock, unlike
session_worker's outside-lock discipline: this slot is
is_alive()-gated, false for a constructed-but-unstarted thread, so
an outside-lock start would open a double-drain window.
- A /command whose worker never spawned answers 503
{"status": "error"} (spec + docs + a pane error arm) instead of the
generic 200 ok that told SDK callers their /clear ran.
- The compaction lifecycle emitter is raise-proof at its single
dispatch tail: a raising duck-typed hook degrades to a lost render,
never a lost end event — previously a raising on_error or a raising
failed-end emit left every pane a frozen progress bar, and a raising
SUCCESS end after the committed swap fabricated a failed end.
- The client settle matrix lives once: composer_queue's
settleSendResponse owns every /send response arm for both panes
(the near-verbatim twins were already drifting), parsePriority is
shared, and the busy stamp is centralized in setBusy(b, source) with
"server" as the fail-safe default. Deferred sends release the
composer (no worker exists for them; retracting the chip no longer
strands the pane in Stop mode), queue_full on an idle-looking pane
removes the optimistic bubble and restores busy (the refusal can now
fire with no worker and no drain to ever emit a state event), and
the pre-bind settle buffer is TTL-based — a burst of deferred
dispatches parked this tab's own raced settle first, where the old
size cap evicted exactly it.
- The command backstop / console proxy timeout inequality is enforced
by a test importing both named constants (both proxy_client
constructions, startup and the mTLS re-create); the compaction card
wears blue (magenta is reserved for the MCP surface); the redundant
TerminalUI.on_compaction override is gone (the inherited protocol
default is the policy site).
Completes the defer-and-drain seam against the matrix rows round 6 never
enumerated (the defer contract itself took no hits):
- Crash row: a claimed entry survives a dispatch crash — the
per-iteration handler re-inserts it at head (claim-flagged so a
claim-section failure can't duplicate it), backs off ~1s, retries.
The last-resort handler spawns no successor (Thread.start fails under
the exact exhaustion that reaches it): the route's ensure-drain stays
the single spawn site, so single-flight is structural and a dead
drain revives on the next defer.
- Order row: the pending list is the order authority. The /send route
pre-checks pending/drain-alive under the same lock acquisition that
appends (one _defer_send helper serves the barrier and command-window
triggers); the coordinator adapter refuses via its return value; the
queued-nudge wake gate yields to pending sends and is re-armed by the
drain's clean exit — which covers lists emptied by pure retraction —
as well as every deferred turn's exit; retry-after-rewind is a
documented accepted overtake; init/create is fresh-ws-by-construction.
- Client settle row: queued responses carry "deferred": true
(SendResponse + regenerated openapi-server.json, status enumeration
completed); bind(el, msgId, {deferred, attachedCount}) replaces the
_deferredAttachments expando; the idle sweep skips deferred and
unbound chips; the shared dispatch attempt emits pane-tier
message_dispatched (folded: true for interjection fold-ins — the chip
clears only its deferred flag and keeps a live x while DELETE still
genuinely retracts); settles that beat bind() park in a bounded
buffer; an idle-thinking pane retro-converts its optimistic bubble
into a real queued chip instead of presenting a parked message as
sent. Rejection polling waits on the slot flags — one dispatch
attempt per slot-state change, not 4 Hz.
- SessionUI.on_compaction's protocol stub became a real default body
(the classic on_info rendering): explicit subclasses inherit protocol
members as real methods, which defeated _compaction_event's getattr
fallback for exactly the pre-1.8 embedders it serves.
- _coerce_event_id() rejects bools (isinstance(True, int) is True) at
all three duck-typed event-id coercions: the compaction marker stamp,
on_system_turn's persisted return, and _ui_event_id.
- Quick-command backstop 60s -> 25s, under the console proxy's 30s so
the degraded "running" answer can traverse a proxied pane (which now
surfaces it); /resume docs drop the fictional history SSE event
(clear_ui + REST re-fetch is the contract); /send response docs match
the wire.
Replace park-and-abandon /send semantics with defer-and-drain: a send
landing in a command window is answered {status: queued, msg_id}
immediately and dispatched full-fidelity by a per-workstream drain
thread when the window closes. Parking encoded client disconnect as
message retraction — true only for the composer's ✕-abort; every
bounded caller (coordinator client and console proxy at timeout=30,
SDKs, stock proxies) timed out and lost its message for the whole
window, and the compensating client machinery was racy (one-shot
sendAbortMs sample) and over-broad (_sendAbort fired on the
interjection path, dispatching dismissed messages while showing a
connection error). Dismissal is now uniformly bind() → DELETE, with a
fall-through that retracts pending entries; retracting an
attachment-bearing deferred send surfaces the discarded-attachments
consequence. The drain claims entries under ws._lock immediately
before dispatch (DELETE can never remove an in-flight message),
refuses the truncating interjection fallback for oversized or
attachment entries atomically inside the enqueue callback, and never
gives up while the workstream lives; durability is documented as
node-local at-most-once. sendAbortMs, _sendAbort, the 600s bound and
the park loop are deleted; route and drain share one dispatch
implementation (spawn metrics included).
Also: the initial-send completion notify is un-gated from slot
ownership (_fire_notify_targets has exactly one call site — successor
turns never notify, so the round-5 guard prevented a duplicate that
cannot exist while converting force-cancel into permanent notification
loss for scheduled workstreams); /compact on an ERROR workstream
restores the badge instead of stamping idle over it; duck-typed
SessionUIs without on_compaction get the classic on_info lines back
via a shared renderer (superseded OK ends included — a committed swap
must never be silent; pre-1.8 SSE clients are deliberately not
dual-emitted, documented as a 1.8 breaking change); failed-end notice
suppression is computed once by the emitter as a notice bool on the
end event (SDK py+ts), replacing the hand-synced cli/JS policy while
the panes keep their pane-local card-ownership clause.
Compaction becomes visible: a first-class 'compaction' SSE lifecycle
(start/progress/end, compaction_id-correlated, superseded-flagged ends)
replaces the loose info lines; both web panes render a progress-bar card
that settles into a persistent result card, re-rendered after reload via
the /history projection of the compaction marker row. Slash commands echo
as command chips instead of fake user turns.
The enabling rework: /command dispatches onto the workstream worker slot
(the old inline path blocked the node's event loop for whole compactions
and let /clear interleave with live turns). Busy refusals answer 409;
quick commands are awaited loop-natively with a 60s backstop; /compact is
fire-and-forget. Sends during a command window park in the /send route
and dispatch full-fidelity afterwards — the interjection queue (length
cap, cross-user guard, identity-swap hazards) is unreachable there — with
a compaction-aware client abort bound shared by both panes. compact_now()
carries send()'s full generation discipline; Stop aborts the in-flight
summary HTTP stream via a generation-scoped cancel ref; force-abandoned
compactions retire at their next checkpoint and their stragglers are
fenced off every surface (panes, pill latch, CLI). Every session retry
backoff is cancel-aware via one shared helper. Docs, OpenAPI spec, and
both SDKs updated.
Verified: 9457-test non-live suite, JS pin suites, headless-Chrome
reducer harness; five unprimed multi-agent review rounds (correctness
trend 15/6/6/4/4) with plan-level design passes on every fix round.
str | None under-specified the field: the implementation and the TS SDK
union both constrain it to queue_full / refused_closed, and the Literal
projects a proper enum into the generated OpenAPI spec so clients
reject unexpected values. Specs regenerated.
Wake path:
- Denial metacog nudge moves to the tool channel so it drains with the
denied tool batch instead of the next user-message seam.
- wake_workstream_if_pending: shared wake gate for watch fires on
already-idle workstreams (no IDLE transition for the watcher to
observe), wired as wake_fn at every set_watch_runner site via the
shared _watch_fire_wake_fn helper (closes over the Workstream OBJECT
— after eviction+restore an id-keyed manager lookup would miss).
- session_worker exit backstop re-runs the wake gate the moment worker
ownership clears: IDLE fans out on the worker thread, so
transition-time wakes always landed on the reuse path and no-op'd
(the coordinator idle_children strand).
- deliver_wake_nudge_from_queue contains GenerationCancelled — it is
the wake worker's run() closure and only Exception is caught
downstream.
Watch delivery:
- Terminal fires that cannot reach their workstream are HELD and
redelivered on min(interval, 60s) without re-running the command,
bounded by MAX_DELIVERY_ATTEMPTS per cycle and the watch's own
max_polls across cycles; the poll charge commits durably at hold
time so restarts stay budget-bounded.
- Restore admission control: per-ws dedup + MAX_CONCURRENT_RESTORES
cap, presence-only re-check under the lock, detection-only stall
alerts (reclaiming a wedged admission would trade capped degradation
for total poll-pool collapse).
- Permanent-vs-transient restore taxonomy: corrupt persona stamp and
genuinely-missing history (confirmed by a raising storage probe —
the resume loader swallows read blips into []) deactivate the watch
immediately; everything else holds and retries.
- Cancel-race defense: delivery paths re-check is_watch_active before
stashing/dispatching, cancel paths write the row BEFORE
forget_terminal_dispatched, the HTTP cancel endpoint clears runner
state, and a per-tick sweep bounds the residual stash-after-clear
interleaving to one check_interval.
- Abandon/exhaustion commits are write-then-clear so storage that can
read but not write retries the row write instead of re-running the
command every cycle; the fresh-fire unrestorable path stashes before
its deactivation write for the same reason.
Registry follows identity:
- The dispatch registry is keyed by _ws_id at registration time; every
rebind now moves it: non-fork resume() and /new go through
_follow_watch_registration (new key live before the old is removed,
never stealing a registration another live session holds), removals
are owner-checked so tearing down a watch-restore shell or a
resumed-away session cannot unregister a live pane, the restore
shell yields to a registration that appears mid-restore, CLI
--resume registers after the successful resume, and both the open
path and the detail-GET lazy rehydrate wire the registration.
Teardown gating and backpressure honesty:
- cleanup_session_ui marks ws._closed FIRST under ws._lock — every
teardown path (close, close_idle, evict, delete, discard) funnels
through it — and session_worker.send re-checks under the same lock,
so a wake can never spawn a worker on a torn-down workstream.
- Create responses carry initial_message_status when the initial
message could not be delivered (queue_full / refused_closed) instead
of reading as success; staged attachments survive for the retry;
/send surfaces a closed workstream as 404 rather than queue_full.
Docs/spec: OpenAPI artifacts regenerated; api-reference documents the
new create-response field; TS SDK type extended.
Tests: ~30 new pins (cancel races, budget durability across restarts,
owner-checked registry moves, teardown gating, stall alerts,
backpressure surfaces, wait_until final re-check); wide subsystem
sweep green (2353 passed).
Three server.test.ts / server-attachments.test.ts cases still asserted
the pre-verb-lift send shape (POST /v1/api/send with ws_id in the body).
The server route has been POST /v1/api/workstreams/{ws_id}/send (ws_id
in the path, {message} body) since that lift, and the SDK send() was
updated with it — only these expectations rotted. They fail on main
too; unrelated to approvals, folded in here to leave the TS SDK suite
green. Test-only, no SDK source change.
ApproveRequestEvent.cycle_id and ApprovalResolvedEvent.cycle_id /
call_ids were typed required, but they are 1.7 additions: a pre-1.7
server omits them on the wire, so a current SDK talking to an older
node sees undefined. The UI and channel adapters already keep the
legacy no-selector fallback for exactly that case. Mark them optional
so consumer code can't assume a string that may be absent — matching
the Python SDK, whose dataclasses default all three.
The checked-in openapi-server.json / openapi-console.json still
described the removed singular pending_approval_detail field; re-run
generate-types.py so the reference specs carry the
pending_approval_details list + cycle_id. Retire two docstring
references to the deleted singular serializer and one stale comment.
POST /approve accepts cycle_id / call_id selectors and 409s on stale
selectors with the current cycle's ids so clients re-render instead of
silently resolving an unrelated batch. Selector-less bodies pin the
resolve to the cycle the lookup returned (not "whichever is oldest by
the time the resolve runs"), and Approve+Always names apply only after
the pinned cycle actually resolved — the auto-approve whitelist can no
longer describe a different batch than the one that resolved.
approve_request carries cycle_id; approval_resolved carries cycle_id +
call_ids; SSE reconnect replays every live cycle's card. The console
collector, coordinator UI fan-out, and both SDKs (Python + TS) thread
the cycle correlation through.
BREAKING (1.7): the singular pending_approval_detail field is removed
from dashboard rows, workstream detail, and node snapshots — replaced
by the pending_approval_details list (one entry per live cycle, each
carrying its cycle_id). stable/1.6 keeps the old shape.
Spec models now describe what the endpoints do: ListPersonasResponse
declares the tool_inventory the shelf depends on, both console create
models declare persona, CreatePersonaRequest declares org_id, and
UpdatePersonaRequest documents the null-vs-absent split (null clears
base_prompt/tool_allowlist, null on flags/kinds is ignored). Console
OpenAPI regenerated.
Protocol contracts match the implementations: update_persona's return
covers the no-op case, create_persona's raises-list is complete, and
both extended row-shape docstrings gain their tail columns plus the
append-only rule. The workstreams.persona comments say slug, not
display name.
Page corrections from the docs review: personas.md documents the
creative_mode-to-writer migration conversion, the mid-session /resume
MCP-lever behavior, visibility-based nudge gating, the soft-set
prompt-cache cost, and the executive tool list — and drops internal
jargon. The changelog entry moves under [Unreleased] with the house
breaking-marker style and the auto-conversion note. coordinator-skills
and the API tour stop using persona to mean framing; governance,
api-reference, sdk, console, tools, and memory pick up the new
permission family, endpoints, kwargs, picker, and lever caveats.
The persona resolved at creation is snapshotted into workstream_config
(five keys, all-or-none) and applied ONLY from the stamp — the personas
table is never read post-create, so edits/archives never touch existing
workstreams, and a corrupt stamp fails construction loudly instead of
silently reverting to a default envelope. Legacy pre-063 workstreams
carry no keys and keep today's behavior byte-for-byte.
The four levers (turnstone/core/personas.py holds the codec):
1. Base override — compose_system_message(base_override=...) replaces
exactly the BASE module; ENV/CONTEXT/TOOLS/POLICIES keep composing so
mandatory prompt policies ride on top of every persona. This also
closes the old /creative hole where the fork bypassed composition
(no CONTEXT, no DB policies).
2. Tool visibility — the allowlist intersects both the composition name
set (TOOLS block self-suppresses, tool-gated policies drop, the
memory advisory drops) and the END of _get_active_tools so the wire
never advertises hidden tools. tool_search in the set = soft
(discovered tools union with the allowlist via the session's
expanded-names set); absent = hard (the whole pathway is disabled,
covering provider-native defer_loading, which has no synthetic name
to filter). Persona sets force client-side tool search.
3. MCP gate (session-wide) — an MCP-off persona drops the client
reference at construction: no merge into _tools OR _task_tools, no
listeners, refresh callbacks inert, resource/prompt catalogs gone.
4. Memory (own hands only) — no recall injection, memory-directed
nudges suppressed (MEMORY_NUDGE_TYPES; behavioural nudges keep
firing), memory tool hidden. _task_tools is NOT filtered; compaction
spill/markers are never persona-gated, and the post-compaction recall
pointer is emitted only when the recall tool is actually visible.
Threading: the create handler resolves once (explicit name -> 400 on
unknown/disabled/kind-mismatch; empty -> the kind's default; pre-seed DB
-> unstamped legacy) and stamps via constructor kwargs + config keys +
the workstreams.persona column; SessionManager.open threads the stamp
pre-construction exactly like the saved model alias. Non-fork resume
adopts the target's stamp so _save_config can't clobber it. spawn /
spawn_batch gain a persona arg with prep-time validation (children are
interactive-kind; omitted = kind default, never the parent's). Python +
TS SDKs, OpenAPI specs, the picker feed GET /v1/api/personas (authed, no
perm), and console admin CRUD /api/admin/personas (persona.* perms,
archive-only — no DELETE) round out the surface.
BREAKING: /creative is removed (the REPL command now points at the
writer persona); turnstone --persona <name> is the replacement. Also
fixes the CLI session factory, which TypeErrored on the project_id
kwarg the shared InteractiveAdapter passes unconditionally.
* feat(projects): governed project containers — memory scope, grouping, manage UI
A workstream can attach to a project: a first-class, shareable resource
container that owns a `project` memory scope, groups conversations, and is
managed from the console.
Storage / migration 062: projects + project_members tables, workstreams.
project_id, and the memory type default project→general; grants
project.{create,read,write,delete} (admin-default).
Recall + writes: project memory is recalled iff the workstream is attached AND
the user has access (owner ∨ member ∨ public-for-read), resolved once at session
construction; coordinators recall it too. New saves default to the project when
attached + writable; the save and delete paths are write-gated; deleting a
project purges its scoped memory; archived projects aren't recalled.
Access = RBAC capability ∧ per-project ACL (auth.resolve_project_access, a
single-fetch resolver); visibility changes, member management, and delete are
owner-only.
API: project CRUD routes on both the server and console; project_id threaded
through workstream creation, spawn inheritance, the cluster-create proxy, the
dashboard / snapshot / coordinator row builders, and the collector deltas.
UI: a project picker with an inline "+ New project" creator in every creation
box (console launcher + standalone dialog + dashboard); group-by-project in the
rail; a project badge in the composer and on dashboard rows; a console manage
tab (list + create/edit + members shelves). The admin Memories view gains
coordinator/project scope filters and human scope labels (name, not hex). The
memory tool schema documents the project scope and the attach-aware default.
* fix(projects): client refresh hardening, creator race guard, SDK project_id
Addresses PR #724 review feedback plus two bugs found while validating it.
- projects.js refreshProjects: a non-OK status (e.g. 403 when the caller
lacks project.read) or a network/parse error no longer blanks the cache
or masquerades as "no projects" -- the prior cache is preserved, the
failure is recorded (new projectsError()) and warned. Honors the
long-standing "a transient error can't blank the rail" docstring.
- projects.js _fp: the fingerprint separators were raw control bytes,
which made git treat the whole file as binary (no reviewable diff).
Rewritten as escape sequences instead of raw bytes -- behavior is
byte-identical at runtime.
- project_creator.js: createProject() could reject unhandled (authFetch
throws on network/401; r.json() throws on a non-JSON body), leaving the
widget stuck busy/disabled. Added a .catch, plus a generation guard so a
create whose widget was cancelled/reopened mid-flight drops its result
instead of selecting a project the user backed out of.
- types.ts: add project_id to CreateWorkstreamRequest / WorkstreamInfo /
DashboardWorkstream to match the server schemas (was SDK-invisible).
- test_project_api.py: move side-effecting HTTP calls out of asserts so
the requests run even under python -O.
* fix(projects): JSON.stringify the cache fingerprint, drop control-byte separators
_fp joined fields/rows on raw NUL/SOH bytes, which made projects.js read as binary to git. Replace with a collision-proof, escape-free JSON.stringify encoding -- same change-detection semantics, zero embedded control characters.
- Remove the unused PerceptionUnavailableError (never raised/caught/imported).
- Reword the now-shipped 'Phase 3' placeholder comments on the Anthropic + OpenAI-Responses audio paths to describe the live upstream STT/perception fallback (these placeholders are defensive, not pending work).
- Clarify the no-vision image fall-through comment (fires when perception is unconfigured OR can't see, not only the former).
- Type AttachmentInfo.kind as the image|text|pdf|audio union in the TS SDK.
- extract_pdf_text: append the truncation marker only when there's actual text, so a scanned PDF over the page cap returns '' (-> placeholder) instead of a content-free document part.
- composer: accept pdf/audio in the upload picker; client-side kind
inference for the optimistic chip (server classify_upload stays
authoritative)
- admin Models tab: supports_pdf + supports_audio_input toggles (flow
through the field-aware capabilities merge into ModelCapabilities, so
flipping supports_audio_input on an omni alias enables native input_audio)
- docs: AttachmentInfo.kind, AttachmentUpload, and the TS SDK note pdf/audio
* chore: relicense BUSL-1.1 -> Apache 2.0 for 1.6.0
Flips every license artifact in the tree; 1.5.x and earlier remain
BUSL-1.1 per their release-time LICENSE files. Contributor consent
record: #548 (rationale: #546).
- LICENSE: canonical Apache 2.0 text
- NOTICE: new; copyright line + pointer to THIRD-PARTY-NOTICES
- pyproject.toml: SPDX expression + explicit license-files trio
- Dockerfile: COPY the license trio (hatchling needs them at build)
- THIRD-PARTY-NOTICES: BUSL line reworded; bundled-version drift
fixed (KaTeX 0.17.0, Mermaid 11.15.0, hls.js 1.6.16)
- README badge + License section, CONTRIBUTING inbound-license line,
TS SDK package(+lock), example pyproject
- docs/pgbouncer.md: drop stray ':' introduced in #353
* docs: add CONTRIBUTORS.md
* chore: drop LICENSE leading blank line
The apache.org LICENSE-2.0.txt begins with a newline; the SPDX
canonical text and GitHub license templates do not. Use the
conventional form — detection is whitespace-normalized either way.
- A1: add a shared `operator-context` marker to every operator-context row in
both UIs; the retry-skip walk keys on it, so a trailing watch-result /
guard-finding / idle-children card no longer makes retry regenerate the
wrong turn. Pinned by source-grep tests + a headless-DOM self-test.
- A2: wrap get_content's two sync DB gates (get_attachment + the unbounded
ws-scoped attachment_referenced_in_ws LIKE scan) in asyncio.to_thread so a
long scan can't stall the event loop — matching the module's convention.
- A3: add the HistoryEvent attachments docstring bullet; drop the dead
`interjection` class; document the interactive-only system-context label;
correct the SDK attachments-meta docs to {kind, filename, mime_type}
(size_bytes is not carried through the history projection).
Operator-context system turns (watch results, output-guard findings, idle
children, user interjections) carried their kind (_source) and a flattened
text content, but the structured per-kind fields were dropped at every
persist/deliver boundary — so the UI rendered every kind as one generic
operator bubble and the structured watch-result card was lost.
Wire the structured meta through as the single source of truth:
- Storage: new conversations.meta JSON column (migration 060); threaded
through save_message/save_messages_bulk (facade + protocol + both backends)
and rehydrated in reconstruct_turns onto Turn.meta.extra["source_meta"].
- Canonical: make_system_turn carries meta as one _source_meta dict;
turn_from_dict/turn_to_dict bridge it to/from Turn.meta.extra.
- Live + history: widen on_system_turn(content, source, meta) across all
impls + the SSE payload; surface _source_meta -> meta in the /history
projection. SDK HistoryEvent docs note the field.
- Producers derive both the model-facing content text AND the card from one
meta dict, so they cannot drift: render_output_guard_text, build_watch_
reminder carrying output, idle_children and user_interjection metadata.
- Frontend: addSystemContext / renderSystemTurn dispatch by source to the
watch-result, guard-finding, idle-children, and queued-message cards in
both the interactive and coordinator panes; every untrusted field renders
via textContent.
The meta is a leading-underscore key, stripped before the wire (sanitize_
messages and the native mid-conversation path copy only role+content), so the
per-provider wire payloads stay byte-identical. Additive column, no backfill:
operator turns predating it reload as plain text bubbles.
A deep-dive review of the branch surfaced a budget regression, SDK doc
drift, dead code, and stale docstrings. Each was boundary-spiked before
fixing.
- R1 (regression): by-reference document attachments were invisible to the
token budget — _msg_text_chars returned 0 doc_chars for a
{type:document,attachment_id} placeholder, and the comment's claim that
the budget "lands at calibration" was false (calibration discards
doc_chars). Thread the doc size through _attachments_meta (size_bytes, at
both the live-append and reconstruct build sites) and count it in
_msg_text_chars, guarded against double-counting the inline form.
Regression test added.
- F1: the history-DTO schema description and the TS HistoryEvent docstring
still advertised the removed reminders/advisories keys and omitted the
system role; corrected server_schemas.py + sdk/typescript/src/events.ts to
match the shipped shape. The committed OpenAPI JSON snapshots were already
~679 lines stale on main; their regen is left to its own chore branch.
- D1: removed AttachmentBuffer.take() — dead (no production caller; the
commit path uses discard()) and scope-weak (ws_id only, unlike its
siblings) — with its test and the now-orphaned Iterable import.
- O1: 4 docstrings referenced the moved ChatSession._fold_system_turns →
lowering.fold_system_turns.
`man` and `math` duplicated capabilities already reachable through
`bash`; `plan_agent` is better expressed as a `task_agent` running a
planning skill, and carried a large amount of special-case machinery
(plan-review gate, refinement loop, per-kind model routing). Removing
all three shrinks the tool surface and cuts per-call token cost.
Also removed, as dead-once-the-tools-are-gone:
- the `math` sandbox executor (`turnstone.core.sandbox`) and its
`[sandbox]` extra; the eval analyst now runs bash-only
- the read-only `AGENT_TOOLS` sub-agent tool set and the `agent`
tool-metadata key (`task_agent`/`TASK_AGENT_TOOLS` retained)
- the plan-review protocol end to end: the `on_plan_review` UI hook,
`resolve_plan`, `POST /v1/api/plan` + `POST /v1/api/route/plan`,
the `plan_review`/`plan_resolved` SSE events, and their Python SDK /
TypeScript SDK / OpenAPI / frontend / Discord+Slack bindings
- the `model.plan_alias` / `model.plan_effort` settings and the
registry `plan_model` / `plan_effort` routing fields
TOOLS 31->28, TASK_AGENT_TOOLS 13->11; COORDINATOR_TOOLS unchanged.
BREAKING CHANGE: removes the `man`, `math`, `plan_agent` tools, the
plan-review SSE/HTTP/SDK surface, and the plan_* model-routing settings
from the experimental 1.6 line.
GET /v1/api/workstreams/saved returned only ws_id/alias/title/created/
updated/message_count — too little to drive the planned saved-list table
redesign. Add seven fields, all sourced from already-persisted data (no
migration):
- state, kind, node_id: columns on the workstreams table
- model_alias, launch_skill: from workstream_config via LEFT JOIN
- child_count: COUNT of child workstreams via parent_ws_id
- context_tokens: most recent usage_events prompt size for the workstream
- context_ratio: context-window occupancy (context_tokens / model context
window), computed in the handler so the NULL / zero-window cases stay
explicit and identical across both storage backends
context_window comes from a model_definitions join; aliases defined only in
config.toml are absent there, so context_ratio degrades to 0.0 rather than
reporting bogus occupancy. The Python SDK reuses the Pydantic model; the
TypeScript SDK OpenAPI snapshot and hand-maintained interface are updated.
Tests cover the new storage columns (including NULL-when-absent), the
handler ratio math + zero-window degradation, and the SDK enriched
round-trip.
openapi-server.json / openapi-console.json had drifted well behind
build_server_spec() / build_console_spec() — the committed snapshots are
regenerated periodically (via sdk/typescript/scripts/generate-types.py)
rather than on every schema-changing PR, so accumulated additions (skill
parsing, pending-approval items, model-definition CRUD, etc.) had not been
captured. This resyncs both with no code changes.
Lift the conversation-modifying /rewind and /retry verbs out of the body-keyed POST /v1/api/command into path-keyed POST /v1/api/workstreams/{ws_id}/rewind ({turns:N}) and /retry, as make_rewind_handler/make_retry_handler in SharedSessionVerbHandlers (template: make_close_handler/make_cancel_handler), wired on both interactive and coordinator kinds. Closes the last unlifted conversation-modifying surface — coordinator workstreams gain rewind/retry where they had none — and removes the surviving exception to the post-#422 path-keyed URL convention.
Handler shape: auth gate (coord -> admin.coordinator via permission_gate; interactive -> conversation.modify via accepted_permissions) -> busy-gate -> session.rewind(n)/retry() -> always emit clear_ui (incl. rewind-to-zero, carries #503) -> audit (conversation.rewind/retry on both kinds). Retry re-dispatch reuses the shared session_worker.send via a per-kind dispatch_retry closure (hard-reject on busy), not a third hand-rolled thread.
The web /command handler now rejects /rewind+/retry with a pointer to the path-keyed endpoint (BREAKING; 1.6.0aN-tolerant); session.handle_command's branches stay for the terminal CLI. auth.py adds the verbs to both write suffix-sets; Python + TS SDKs, OpenAPI (RewindRequest + server/console specs), the /route/ proxy mounts + audit actions, and coordinator_client all gain them.
Interactive frontend (app.js): the 3 /command POST sites + the hand-typed-slash reroute now hit the path-keyed endpoints; the bare .msg.user rewind selector is kept (matches the server's _find_turn_boundaries, which counts system-nudge user turns). The coordinator frontend rewind UX lands in a follow-up commit (browser-verified).
Tests: route-walk mount/order, /route/ audit rows, required_scope, OpenAPI catalog, SDK body-inspection, and HTTP-level handler behavior (busy-gate, turns validation, clear_ui emit, retry dispatch, audit invocation + swallow).
PR #498 round-robin review surfaced 5 findings. 4 applied; 1 rejected
with rationale.
Applied
* **Copilot finding 5** (history_decoration.py:341): dispatcher
inspected only ``provider_content[0]['type']``. OpenAI Responses
captures EVERY ``output_item.done`` event into ``provider_blocks``
(not just reasoning) — in practice the order is
``[reasoning, message, ...]`` but the API doesn't guarantee that;
a hypothetical ``[message, reasoning]`` ordering would silently
drop the reasoning under an index-only check. Now walks the list
for the first block whose type is in ``_BLOCK_TYPE_PROVIDER_FACTORY``,
then dispatches the WHOLE list to that provider's extractor. Each
provider's extractor already filters internally by its own block
type, so passing the full list is correct. Regression test added
(``test_dispatcher_scans_past_unrecognized_first_blocks``).
* **Copilot finding 3** (migration 052 docstring): the previous
review-fix wave used sed to rename ``persist_reasoning`` →
``surface_persisted_reasoning`` everywhere, which mangled a
historical reference in the migration docstring ("The earlier name
``surface_persisted_reasoning`` was renamed..."). Restored to
point at the actual pre-rename name (``persist_reasoning``).
* **Copilot finding 4** (sdk/typescript/src/events.ts:26):
``HistoryEvent`` JSDoc still referenced ``persist_reasoning`` —
the sed rename only walked ``turnstone/`` and ``tests/``, missing
the TypeScript SDK. Updated to ``surface_persisted_reasoning``.
Also widened the comment to cover all three reasoning-bearing
block types (Anthropic ``thinking``, OpenAI Responses ``reasoning``,
synthetic ``reasoning_text``) instead of mentioning only Anthropic.
* **github-code-quality finding** (session.py:1120): ``_resolve_server_type``
had a bare ``except Exception: pass``. Replaced with a
``log.debug(..., exc_info=True)`` + explanatory comment. Behaviour
unchanged (still returns ``""`` on any lookup failure); failures
are now observable under DEBUG triage.
Rejected (with rationale)
* **github-code-quality finding** (_protocol.py:265):
``extract_reasoning_text``'s body is ``...`` per ``LLMProvider``
Protocol convention. Every method in the file uses ``...`` (PEP
544 idiomatic Protocol style). Changing only this one to
``raise NotImplementedError`` would be inconsistent with the rest
of the file. CodeQL's "statement has no effect" warning is
technically correct for ``...`` as a standalone expression but
ignores the documented Python Protocol convention. No fix.
Docs sync
* docs/api-reference.md: ``history`` SSE event message-shape table
gains the optional ``reasoning`` field.
* docs/architecture.md: ``ModelCapabilities`` row in the type table
gains ``supports_reasoning_replay``; ``StreamChunk`` and
``CompletionResult`` rows gain the existing ``provider_blocks``
field (was missing pre-PR). New "Per-model reasoning persistence"
subsection under the Models config section, documenting the two
flags + capability gate + three reasoning paths + cross-provider
shape filter.
* docs/settings.md: new "Reasoning persistence (per-model)"
subsection with the two-flag table and capability-gate note.
* docs/diagrams/03-core-engine-classes.puml: ``LLMProvider`` interface
adds ``extract_reasoning_text`` + the new ``replay_reasoning_to_model``
kwarg; ``ModelCapabilities`` class adds ``supports_reasoning_replay``.
PNG regenerated.
Lint + test gate

* pytest -m 'not live' — 6116 passed (3 deselected), +1 net new test
(``test_dispatcher_scans_past_unrecognized_first_blocks``).
Surface stored Anthropic thinking blocks on /history responses so
refreshing the page rehydrates the reasoning bubble. Wire payloads
unchanged. Per-model operator knobs added to model_definitions for
both UI rehydration and (Phase 2) wire-build replay.
Why now: reasoning is already round-tripped via _provider_content for
Anthropic-with-thinking turns, but never surfaces on the history wire,
so a tab reload showed only the final answer with no rationale.
Operators also have no per-model lever to opt out of UI display or to
opt in to replay-to-model on subsequent calls.
What this change does
* Migration 052 adds two boolean columns to model_definitions:
persist_reasoning (default 1) controls UI rehydration; replay_
reasoning_to_model (default 0) reserved for Phase 2's wire-build
shape filter. Mirrors the enabled column pattern (NOT NULL +
integer server_default).
* LLMProvider Protocol gains extract_reasoning_text(provider_blocks)
with concrete impls on AnthropicProvider (walks type=='thinking'
blocks, joins with newline, caps at 64 KiB) and no-op stubs on
OpenAIChatCompletionsProvider + OpenAIResponsesProvider. Google
inherits the no-op via OpenAIChat. Phase 3 will wire the OpenAI
Responses extractor once include=['reasoning.encrypted_content']
is requested.
* turnstone.core.history_decoration gains a structural dispatcher
extract_reasoning_text_from_provider_content keyed off the first
block's type field (Anthropic 'thinking' / OpenAI Responses
'reasoning' / Gemini 'thought' are non-overlapping by API design).
Both history surfaces use it: _build_history calls the dispatcher
directly (the SSE-replay path builds entry dicts from scratch),
and the lifted make_history_handler runs the list-helper variant
in the existing to_thread block.
* make_history_handler resolves persist_reasoning via three tiers:
live session -> workstream_config.model_alias (the same key
SessionManager uses to rehydrate the original model after process
restart) -> conservative True default. Operator flag-flip takes
effect uniformly on both warm and cold workstreams.
* Frontend: app.js replayHistory and coordinator.js role==='assistant'
branch each call the existing reasoning-bubble construction (for
app.js, the document.createElement pattern from the live SSE
handler; for coord, the appendMsg('reasoning') helper) when
msg.reasoning is non-empty. Reasoning bubbles render before the
content bubble, matching live SSE order.
* Admin UI: two checkboxes ('Persist reasoning', 'Replay reasoning
to model') in the model edit modal, plus override-pill display in
the model row when set to non-default values.
What is intentionally out of scope
* Phase 2 -- ANTHROPIC_VALID_BLOCK_TYPES shape filter at
_anthropic.py:312-316, _convert_messages replay_reasoning_to_model
parameter, thinking-strip branch, _msg_text_chars token-calibration
extension. The replay flag is stored but not consumed on the wire.
* Phase 3 -- OpenAI Responses include=['reasoning.encrypted_content'],
Gemini include_thoughts spike, ModelCapabilities.supports_
reasoning_replay.
* Phase 4 -- Local-model / chat-template reasoning persistence
(session.py:3486 reasoning_parts accumulator).
Tests
* AnthropicProvider.extract_reasoning_text -- 13 unit tests covering
None / empty / mixed / multi-block / cap / malformed / non-list
inputs plus other-provider no-op verification (real provider
instances, no mocks).
* extract_reasoning_for_history -- 10 dispatcher tests including
block-type discriminator routing (thinking vs reasoning vs
unknown), strip-when-flag-false, empty / non-dict guards, and
cross-role isolation.
* _build_history -- 6 boundary tests through the real Anthropic
extractor with stub sessions, including the registry-lookup
failure default-True branch.
* make_history_handler -- 5 round-trip tests through real storage:
the storage layer's reconstruct_messages decodes provider_data
into _provider_content, and the helper extracts through the real
AnthropicProvider. Includes the live-session flag honoring path,
the cold-workstream workstream_config lookup path, and the
no-alias default-True fallback path.
* Audit-log discipline -- 4 structural mock-and-assert tests that
capture every Logger.info / warning / error call across the
pipeline (extractor, dispatcher, list-helper, _build_history)
and assert no captured payload contains a marker reasoning string.
* model_definitions storage -- 6 round-trip tests: default flags,
explicit create with both flags, individual update of each flag,
and list-includes-flags assertion.
* model_registry -- 4 tests: dataclass defaults, dataclass with
explicit flags, DB-row-mapping with both flags, and pre-052
legacy-row default-fallback.
Edge cases pinned by the test suite
* Pre-052 DB rows missing the new columns degrade to dataclass
defaults (test_db_reasoning_flags_default_when_absent).
* Live session in memory has its flag honored (test_history_handler_
with_persist_flag_false_via_live_session).
* Cold workstream resolves the flag via workstream_config +
app.state.registry (test_history_handler_cold_workstream_resolves_
via_workstream_config) -- this closes the gap where a process
restart would have silently un-honored an operator flag-flip.
* Cold workstream without persisted model_alias falls through to
default True (test_history_handler_cold_workstream_no_alias_
defaults_true).
* Foreign / unknown / missing block types degrade silently to no
reasoning field rather than misroute or crash.
Lint + test gate

Refreshing a coordinator or interactive workstream pane while the LLM
is mid-stream now restores the partial assistant text + reasoning
immediately and flips the composer back to stop-mode, instead of
showing nothing until the response completes.
Per-turn inflight buffers (`_ws_inflight_content`, `_ws_inflight_reasoning`,
`_ws_inflight_seq`) on `SessionUIBase` are kept separate from the
existing multi-turn `_ws_turn_content` buffer that drives the
dashboard's IDLE-piggyback payload. New `on_turn_start` (top of
send-loop, defensive) and `on_turn_committed` (right after
`messages.append(assistant_msg)`, primary) lifecycle hooks reset
inflight at turn boundaries. The seq counter is monotonic across
turns so a long-lived subscriber's `snap_seq` cutoff stays valid for
the lifetime of the connection — resetting per-turn would silently
drop turn N+1's first M tokens (M = whatever was streamed pre-snapshot
in turn N).
`snapshot_and_consume_state_payload` also drains inflight at idle/error
so cancel and exception paths don't leak stale text. New
`register_listener_with_in_progress_snapshot` atomically registers a
listener and snapshots the inflight buffers; `make_events_handler`
emits a `state_change` event (so the JS busy machine flips to
stop-mode) followed by a one-shot `in_progress_snapshot` after the
kind-specific replay, then strips the internal `_seq` field from
yielded live events while filtering against `snap_seq`. A per-listener
shallow `dict` copy in the live drain prevents the multi-tab race
where one listener's `del event["_seq"]` would corrupt another
listener's filter view.
`_synthesize_cancelled_results` now emits synthetic `on_tool_result`
events for each cancelled tool so live coord tabs can drop the
newly-additive `coord-tool-batch--running` indicator cleanly. The
indicator now coexists with `--auto`/`--approved` (applied on
`tool_info` and `approval_resolved` approved; removed when every row
in the batch has a result), making live tool execution visually
parallel to the replay-time orphan rendering.
Frontend handlers in `app.js` (interactive) and `coordinator.js` (coord)
absorb EventSource auto-reconnect re-replays via a length-based
prefix check on the in-progress buffer. New `InProgressSnapshotEvent`
+ `StateChangeEvent` dataclasses in the Python and TypeScript SDKs
with type guards.
`_MAX_TURN_CONTENT_CHARS` lifted 256 KiB → 512 KiB (single constant
for both buffers — headroom for current commercial models).
Regression tests cover race-free composition under concurrent writers,
seq-filter dedup invariants, the cross-turn seq monotonic invariant,
idle/error inflight drain, synthesized `on_tool_result` on cancel
(including UI-hook failure isolation), and the multi-listener
shared-dict invariant.
Four themes from a coordinator-feature shakedown:
1. Correctness fixes (return shapes / examples / behavior)
- tools_coordinator.md: drop fake skill names from spawn examples;
fix wrong kwarg ``node_id=`` → ``target_node=``.
- wait_for_workstream.json: document ``message`` + ``truncated``
per-ws fields (always enriched in the client; the JSON shape
lagged the docstring).
- cancel_workstream.json: document the conditional ``dropped``
payload — ``was_running`` always present when ``dropped`` is,
``pending_approval`` and ``queued_messages`` conditional sub-shapes.
- spawn_workstream.json: document full return shape including
``routing_strategy ∈ {rendezvous, target_node, resume}`` and
``status``.
- close_all_children.json: clarify ``skipped`` covers BOTH
hard-deleted children AND already-closed-and-evicted children
(wire shape doesn't distinguish); drop incorrect "echoed back
in response" claim — server returns ``{status, closed, failed,
skipped}``, never echoes ``reason``.
- console/server.py: comment in ``_fanout_on_children`` clarifying
that the 400 "No session" branch fires for cancel-cascade
callers and is unreachable from close_all_children (close
handler 404s instead).
- coordinator_client._utc_now_iso(): switch to bare ISO format
matching the rest of the storage row format used in the codebase.
2. Tightened the 11 longest tool descriptions (~23% cut on the
coord set). Removed ALL-CAPS emphasis, normalised em-dashes,
dropped informal phrasing. No new claims.
3. Removed static approval annotations from descriptions.
Approval is governed at runtime by the unified ``approve_tools``
body and admin-defined ``tool_policies`` (#436); static
"Auto-approved" / "Approval required" / per-action approval
tags become a stale signal. Field names (``pending_approval``)
and operational verb behaviour ("cancel unblocks pending
approvals") stay.
4. Renamed ``task_list`` coord tool → ``tasks``. The previous name
compounded the bare word ``task`` (which collides with chat-template
channels on local models — same reason ``task_agent`` carries
the suffix); the plural form sidesteps the collision and reads
more accurately, since the tool acts on the whole list rather
than a single task. Sweep covers tool JSON, Python methods (5
client methods + 2 session methods + 1 helper + 1 constant),
audit event name (``task_list.update`` → ``tasks.update``), log
tag (``task_list.corrupt_envelope`` → ``tasks.corrupt_envelope``),
frontend SSE event matcher, prompts, docs, and tests. CHANGELOG
entry added.
Plus: dropped the ENV block (Output Environment / Available
rendering / Formatting principles) from coordinator system
prompts. Coordinators orchestrate rather than render rich output
to the user, so the rendering capability matrix is not actionable
for them. Coord prompt drops ~29% (6309 → 4493 chars).
SDK regeneration via ``generate-types.py`` updates both
``openapi-console.json`` (the rename's downstream change) and
``openapi-server.json`` (PR #436 drift — its merge added
``pending_approval_detail`` + ``recent_auto_approvals`` fields to
the Python schemas but didn't regenerate the JSON artifact).
## Behavior changes (operator-visible)
- Audit event name: ``task_list.update`` → ``tasks.update``.
Audit dashboards / SIEM filters / log greps that pinned the old
prefix should update.
- SSE ``tool_result`` events now ship ``name="tasks"`` for the
scratchpad tool. The bundled coord-tree UI is updated atomically;
external consumers reading SSE events by tool name need to update.
- Existing task envelopes in production storage have ``+00:00``
timestamps from the old ``_utc_now_iso``. New writes are bare;
old rows are not backfilled. Within an envelope you may briefly
see mixed formats until each row is re-touched. No code path
string-compares timestamps within an envelope, so this is
cosmetic.
## Validation
- ``ruff check`` + ``ruff format --check`` clean

Copilot review on PR #422 flagged that the DELETE-on-send (dequeue)
EndpointSpec declared no request_model, so the generated OpenAPI
showed no requestBody for an operation that *requires* a JSON body
with ``msg_id`` and 400s when it's missing.
- Add ``DequeueRequest`` to ``server_schemas.py`` with the single
required ``msg_id: str`` field.
- Wire ``request_model=DequeueRequest`` and ``response_model=
StatusResponse`` on the DELETE EndpointSpec; trim the now-redundant
inline body example from the description.
- Re-import the schema in ``server_spec.py`` and add the entry to
``_ALL_MODELS`` so the OpenAPI components list carries it.
- Regenerate ``openapi-server.json``.
Sibling thread on the close EndpointSpec was already addressed in
4000ae2 (request_model=CloseWorkstreamRequest).
4558 tests passing under ``-m "not live"``; ruff + mypy clean.
Copilot caught three real issues in PR #422 review, all clustered
around the close request body contract:
1. The interactive close handler runs with
``supports_close_reason=True``, which calls
``read_json_or_400(request)`` — an empty / non-JSON body returns
``400 {"error": "Invalid JSON body"}``. The previous SDK fix
sent NO body via ``json_body=None``, which would 400 against a
real server. The mock-transport test silently masked it because
the mock answered without inspecting the body.
2. The doc said the body was empty (or ``{}``), with no mention
of the optional ``reason`` field, its 512-byte cap, or the
credential-redaction guard.
3. The Pydantic schema for close was deleted outright; OpenAPI
and SDKs lost their typed shape for the optional ``reason``.
Changes:
- ``turnstone/api/server_schemas.py``: reintroduce
``CloseWorkstreamRequest`` with a single optional
``reason: str | None = None`` field. Docstring documents the
must-be-valid-JSON contract and notes that coord ignores the body
(``supports_close_reason=False``).
- ``turnstone/api/server_spec.py``: re-import the schema, point the
close ``EndpointSpec`` at it via ``request_model=``, restore the
``_ALL_MODELS`` entry. OpenAPI JSON regenerated.
- ``turnstone/sdk/server.py``: ``close_workstream`` (sync + async)
gains an optional ``reason: str | None = None`` parameter and
always sends ``json_body={}`` (or ``{"reason": ...}``) so the
body is never empty. Adds a regression test
(``test_close_workstream_sends_valid_json_body``) that inspects the
raw transport content rather than relying on a path-keyed mock —
the kind of check that would have caught this bug pre-merge.
- ``sdk/typescript/src/server.ts``: ``closeWorkstream`` gains an
optional ``opts.reason`` parameter; reintroduce
``CloseWorkstreamRequest`` interface in ``types.ts`` and re-export
from ``index.ts``.
- ``docs/api-reference.md``: close section documents the JSON-body
requirement, the ``reason`` field, the 512-byte cap, the
multibyte-safe behavior, the credential-redaction guard, and the
non-string-coercion path.
- ``CHANGELOG.md``: amend the 1.5.0 BREAKING block to reflect the
schema reintroduction (slim form, ``reason`` optional) instead of
the prior "removed outright" claim.
4558 tests passing under ``-m "not live"`` (was 4557 — +1 from the
regression test). ruff + mypy clean.
Reviewer caught real misses on the consumer-swap claim:
- TypeScript SDK still defined and re-exported `CloseWorkstreamRequest`
(types.ts + index.ts) — drop both. Now matches the Python-side
removal.
- Four `tests/test_auth.py` cases (`test_write_full_token_ok`,
`test_approve_full_token_ok`, `test_bearer_takes_precedence_over_cookie`,
`test_cookie_full_on_write_ok`) were tautological after the legacy
URL removal: they posted to `/api/send` / `/api/approve` and asserted
`allowed is True`, but those paths now classify as `read` so a read
token would also pass — they no longer tested the write/approve
scope enforcement. Swap to path-keyed URLs to restore the original
intent.
- `is_public_path("/api/send")` test renamed + retargeted to a
path-keyed URL.
Doc-table drift the previous commit missed:
- `docs/security.md` path-to-scope mapping rewritten for the
path-keyed verb family (write set, DELETE-on-/send dequeue,
per-ws_id approve).
- `docs/architecture.md` scope-model row text swap from `/api/send`
/ `/api/approve` to the path-keyed equivalents.
- `docs/diagrams/01-system-context.puml` channel→server edge label
swap.
- `docs/diagrams/15-auth-architecture.puml` scope class swap.
Cosmetic comment-only stragglers:
- `tests/test_session_worker.py` module docstring URL update.
- `tests/test_ratelimit.py` ~11 `/api/send` fixture-key strings
retargeted to `/api/workstreams/abc/send` so the URL fixtures
reflect the post-1.5 surface (rate limiter is path-agnostic; the
swap is purely cosmetic).
4557 tests still passing under -m "not live"; ruff + mypy clean.
