feat(webui): session-event transport unification and web-app run-completion notifications

[BenKurrek]

Summary

• Implements the approved design docs/internal/design/2026-08-13-webapp-run-notifications.md end to end: unified WebUI session-event transport (typed stream contracts + one bearer-authenticated multiplexing session SSE stream) and web-app run-completion notifications (durable notices, live stream, cross-tab/device presentation arbitration, evidence-based read state, OS notifications, and a typed Web Push fallback).
• Replaces the string-typed stream_id + JSON round-trip on the frozen three-method ProductSurface with typed ProductStreamSelector / ProductStreamEventEnvelope / ProductStreamEvent; one shared stream driver + browser codec now feeds both the compatibility per-thread SSE (retained as an API path until its clients are ported) and the new session stream; the dormant per-thread WebSocket route is removed.
• Adds the run-completion notification core in ironclaw_assistant: a CAS-everything notice store on the /run-notices per-user mount (§5.3 state machines, 4 ordered indexes, per-owner monotonic sequence), journal-observer ingest, an arbitration coordinator (1s intent window, 2s grant ack, exactly one re-arbitration, deterministic §5.6 ranking), owner-scoped stream hub with durable replay, and four authenticated HTTP operations — mutations never ride the socket.
• Adds the §7.9 typed outbound vocabulary (RunNotificationEventKind::RunCompleted → OutboundPushKind::RunCompletion, DeliveryTargetCapabilities.run_completions, OutboundPart::RunCompletion) with web-app-exclusive capability filtering and the §7.10 fixed-copy v2 push payload; Slack/Telegram report the part unsupported.
• Reconciles with the durable notification Inbox that landed on main while this was in flight (feat(notifications): add a durable user inbox and product APIs #7697/feat(notifications): publish authoritative run outcomes #7700): the Inbox keeps the bell list for scheduled-trigger runs, run-completions own live presentation for every run; a read bridge marks the run's run_completed Inbox row read when completion evidence settles, and the bell dedupes by run id.

What changed, by layer

Contracts (ironclaw_product_contracts, ironclaw_host_api, ironclaw_extension_contracts)

• Typed product stream vocabulary: kind-tagged ProductStreamSelector::{Thread, RunCompletions}, cursor-carrying ProductStreamEventEnvelope, kind/payload-tagged ProductStreamEvent::{Thread, RunCompletion}. The frozen invoke/query/stream_events method set is unchanged (ratchet-pinned).
• New session_transport module: SessionSocketTicket + SessionSocketTicketStore (mint returns a nonce; consume is exactly-once), 15 s TTL, 1024 outstanding cap.
• New run_completions wire module: notice/grant/clear stream events (schema-stamped), intent/acknowledge/thread-read requests, unread snapshot, operation descriptors (webui.run_completion.{intent,acknowledge,thread_read}.v1, webui.run-completions.unread.v1), and bounds (128 B opaque ids, 250-notice snapshot, 32 intents/notice).
• IngressAuthScheme::SingleUseTicket; OutboundPart::RunCompletion(Box<RunCompletionNoticeView>) (typed fact, no reply content).

WebUI backend (ironclaw_webui)

• webui_v2/session_events/: shared ProductStreamDriver, browser codec (one place decides event names and cursor tokens for SSE and WS), bounded webui.session_event.v1 protocol (8 KiB frames, 64 B sub ids, 16 subs/socket, 16 batches/sub, 5-min lifetime, connection-scoped generations, authorize-then-swap replacement, per-subscription cursors).
• Ticket mint route (POST, bearer, NoBody, 12/min) + ticket-authenticated read-only session socket (same-origin required; the bearer never appears in a URL); the socket dispatches subscribe/unsubscribe/ping only — never ProductSurface::invoke.
• Per-thread SSE now rides the shared driver/codec byte-identically (rollback path); the dormant per-thread WS route/handler is deleted.
• Four run-completion HTTP routes (3 × POST mutation policy 4 KiB/60 rpm, 1 × GET projection read), thin ProductSurface handlers, descriptor-table pins, charter rows (session-events, run-completions), CONTRACT.md route table.
• In-memory single-process ticket store (bounded, TTL-reaping, poison-recovering).

Assistant (ironclaw_assistant)

• run_completions/: records (purpose-separated rcn-/rct- sha-256 identities; delivery/read state machines with grants_issued carried through regress), store (every transition a bounded CAS via the shared helper; keyset pagination with tie-break sentinel; per-tenant durable due-owner registry for boot reconciliation), stream hub (broadcast + durable replay, rc:{sequence} cursor namespace so thread cursors can never resume RunCompletions), ingest (owner-visibility probe + finalized-reply-by-run requirement; retryable errors hold the durable observer cursor; no-reply anomalies advance), operations (idempotent; foreign notices collapse to NotFound; server derives all authority from the bound caller), coordinator (wake-driven + timer, bounded scans, stale-grant metrics), and the §6.1 external half: RunCompletionExternalDelivery implementing both CompletionPushFallback (CAS PushOwned — one replica wins; delivery through OutboundPolicyService + DeliveryCoordinator under the new RunCompletionNotice intent) and LocalOsIntentPolicy (Selected ∧ Enrolled, fail-closed).
• Read bridge: evidence-settled notices also mark the run's run_completed Inbox row read (observer-derived run:{run_id}:completed identity; best-effort, never settlement authority).

Outbound + extensions (ironclaw_outbound, ironclaw_web_app, packages)

• New push kind/event kind/capability field; push-target planning treats the capability-filtered explicit binding as the only RunCompletion candidate (per-thread notification policies never add completion candidates).
• Web-app adapter renders the typed part into the web_app_notification.v2 payload — fixed copy, URL derived from the typed thread id inside the payload builder, opaque collapse tag, capped unread count. Only the web-app provider advertises run_completions: true.

Composition (ironclaw_composition) + CLI

• /run-notices joins PER_USER_ALIASES; notice store built over the shared consumer filesystem.
• RunCompletionJournalObserver (durable cursor web-app-run-completion-observer-v1; terminal Completed top-level agent turns with owner + thread scope; occurred_at timestamps; retryable-only Err).
• Coordinator spawned with boot reconciliation over the tenant due-owner registry; drained in RebornRuntime::shutdown.
• SecretStoreSessionSocketTicketStore (nonce IS the one-shot secret lease id → exactly-once across replicas), selected by DeploymentConfig::storage_shape() — no new Cargo features; single-process shapes use the in-memory adapter; a deployment with neither leaves the capability unadvertised (fail closed).
• Push facade + enrollment probe wired from the channel-host cone when present; Phase-1 fail-closed defaults otherwise.

Frontend (frontend/)

• lib/session-events/: one app-root SessionEventClient per page (per-subscription cursors, generation filtering, liveness pings, reconnect-hint handling, permanent degradation to SSE after repeated ticketless failures).
• lib/run-completions/: lazily-imported orchestrator (snapshot rebase → stream subscribe → §5.6 profile intent from merged BroadcastChannel tab state → HTTP intent → grant application on exactly one tab via profile-local test-and-set → honest acknowledgements), badge store (250-entry cache; durable projection stays authoritative), opaque browser/tab identity, thread-read + reply-render evidence reporting from the chat surface.
• Bell merge with inbox dedupe by run id; toast for in-app grants; i18n in all 11 locales; enrollment carries browser_instance_id inside the channel-opaque document.
• public/sw.js: v2 payload handling, IndexedDB test-and-set dedupe by notice id (250-entry bound), grouped fixed copy, §9.1 click selection (existing client on the path → focusable client → openWindow), tag-based clearing.

Invariants preserved

• Every product mutation is authenticated HTTP; the WebSocket carries subscribe/unsubscribe/resume/ping only and never dispatches ProductSurface::invoke or operation ids. No event-specific streaming routes — only the ticket-authenticated read-only /api/webchat/v2/session/websocket.
• Frozen three-method ProductSurface; typed selectors replace the JSON round trip; no global cursor across logical streams (thread cursors and rc: cursors are disjoint namespaces).
• Chat streaming semantics unchanged: HTTP submit, cumulative phase-keyed live text, coalescing, process-local partials, durable finalized reply — the integration test pins exact byte parity between the socket's final reply and the durable timeline.
• Push payloads carry no generated or protected content (fixed copy; same-origin URLs derived from typed thread ids); streams never authorize push (the push path crosses OutboundPolicyService + DeliveryCoordinator with reply-target revalidation).
• LLM data never deleted: notices, intents, grants, and read transitions are retained with timestamps; caches (worker ledger, UI store) evict, durable rows do not.
• No new Cargo features; deployment shape decides the ticket adapter via DeploymentConfig::storage_shape(); strong types everywhere; async tokio; no production unwrap/expect in the new code.

Persistence and multi-replica

• Notice store: per-notice JSON documents + 4 ensure_index ordered indexes + a per-owner sequence document, all mutated through the shared bounded CAS helper; racing replicas burn sequence numbers but never fork them.
• PushOwned is a CAS from PendingArbitration only — exactly one replica can win; a read between scan and claim stands the fallback down.
• Ticket exactly-once across replicas via the secret-store one-shot lease protocol; in-memory adapter for single-process shapes.
• Boot reconciliation: ingest CAS-marks the owner in a per-tenant due registry before the notice write (registry overflow fails retryably and holds the observer cursor), the coordinator wakes each due owner once at startup, and empty scans clear the registry.
• Stream lag → rebase from the durable unread snapshot; the client resubscribes from the snapshot's resume sequence.

Compatibility and rollback

• Per-thread SSE is retained and served by the same driver/codec — turning features.session_events off (or the shared ticket store being absent) reverts every browser to today's transport with no data migration.
• Wire-tolerant records (version fields, serde defaults — grants_issued, agent_id/project_id are default-tolerant for earlier rows).
• The v1 push payload continues to work; v2 adds optional fields older service workers ignore.
• The removed per-thread WS route was dormant (no production caller); its descriptor/handler/tests were deleted, not stubbed.
• Inbox reconciliation is additive: without the bridge the two systems still function, merely with an unread inbox row until manual mark-read.

Privacy and security

• Single-use tickets: replay rejected, expiry + tenant re-check at upgrade, caller identity injected host-side, same-origin enforced before upgrade, the long-lived bearer never enters a WebSocket URL.
• All arbitration identifiers (browser_instance_id, tab_id, notice/grant ids, thread tags) are opaque and purpose-separated; client claims cannot mint permission or targets — local_os is validated server-side against live target selection + host-owned enrollment, fail-closed on backend uncertainty.
• Foreign notice ids collapse to NotFound; observability is sanitized (counts and ids, never content).

Test Strategy

User behavior: a user asks a question, switches tabs/apps or closes the browser, and is told exactly once — on the right surface — when the reply is ready; opening the thread (or watching it render) clears the notification everywhere without manual bookkeeping.

Risk areas:

• Browser
• Side effect
• Persistence
• Security or permissions
• Cross-component behavior

Tests added or updated:

• Unit or contract: notice store (create/idempotence, intents bounded+replacing, grant lifecycle state checks, push-ownership single winner, read settlement, keyset pagination, due-owner registry), coordinator (ranking, local_os gating, one-re-arbitration-then-fallback, boot reconciliation, read untracking, fallback ownership), records round-trips + identity separation, session protocol bounds, codec, ticket stores (in-memory + secret-lease adapter incl. replay + concurrent single-winner), wire-shape tests in product_contracts, web-app v2 payload grammar, the web-app RegistrationDocument grammar (keys/agent/correlation id, bounds, rejection), the composition enrollment probe and journal-observer filter (per-exclusion), the push facade at the caller seam (run_delivery_contract.rs: capability-filtered target, CAS ownership, typed part, exactly-once re-drive, local_os selection × enrollment matrix), the operations tier (foreign notices → NotFound; thread_read drains past one page and never past the rendered sequence), the stream hub's channel lifecycle, and the four run-completion routes through the real WebUI router (webui_v2_handlers_contract.rs); frontend vitest suites (session client ×5, i18n coverage, device-push correlation, service-worker.test.ts driving public/sw.js against a scripted worker scope, plus the existing suite — 1,509 green).
• Reborn integration: tests/integration/session_events.rs — a completed turn streams over one real session-WebSocket subscription and its final frame is byte-identical to the durable HTTP timeline reply; two logical subscriptions on one socket deliver their own threads independently.
• Reborn integration: tests/integration/run_completion_notifications.rs — the production RunCompletionJournalObserver registered on the harness's real process journal turns a completed user turn into exactly one durable unread notice carrying the run/thread identity, and a second turn extends the owner's monotonic sequence.
• Recorded fixture: Not applicable — no model-behavior change; the loop/driver path is untouched.
• Browser E2E: Not applicable in this PR — OS-notification/service-worker flows need a headed browser + push service. frontend/src/lib/service-worker.test.ts evaluates public/sw.js against a scripted worker scope and drives its own push/notificationclick listeners (one presentation per notice id, grouped fixed copy, same-origin deep-link collapse, v1 payloads, the §9.1 click order); IndexedDB is absent there, so that exercises the memory-ledger path — the IndexedDB ledger and real display are the §15 headed-browser follow-up.
• Backend or runtime: full workspace suite; architecture gates (dependency boundaries incl. re-pinned product_contracts ceiling, retired-taxonomy, typename ratchet with the justified LocalOs* entries, extension-specificity, struct/test-support ratchet, charter maps, same-layer edges).
• Live canary: Not applicable — feature is fail-closed off until a deployment advertises features.session_events.

What the tests prove: the socket transport delivers exactly the durable truth (byte parity with the HTTP timeline); subscriptions are isolated per selector and cursor-resumable; tickets are single-use under concurrency across replicas; every notice state transition is CAS-guarded with one push winner; arbitration follows §5.6 deterministically with the §5.4 bounds actually enforced (the tests caught and fixed a lost-grants_issued bug); read evidence settles notices and bridges to the Inbox; capability filtering structurally restricts completion pushes to the web-app channel.

Security Impact

Adds one new authenticated ingress (the single-use-ticket session WebSocket) and four authenticated HTTP mutations/reads; no new secrets, no new network egress paths (completion pushes ride the existing web-app delivery channel and its declared egress hosts), no tool-execution or sandbox changes. Tickets are random, single-use, 15 s, caller-bound, consumed by the bearer middleware before the handler runs; the bearer never enters a WebSocket URL; same-origin is enforced before upgrade; inbound frames are bounded at 8 KiB at both transport and parser. The socket carries subscribe/unsubscribe/ping only and never dispatches ProductSurface::invoke.

Reborn Trust-Boundary Checklist

• Public policy/evidence/trust-bearing types: SessionSocketTicket is minted only by the ticket-mint handler from the authenticated caller and consumed only by the bearer middleware; TrustedInboundTurnRequest is untouched; notice ownership is derived from the bound caller, never from a browser payload.
• Untrusted content enters prompts only through an envelope/escaping primitive: no prompt construction in this PR; push payloads and stream frames carry fixed copy and typed ids only.
• Hashes declare purpose: notice ids and thread tags are purpose-separated SHA-256 prefixes (web-app-run-completion/v1, web-app-run-completion-collapse/v1); neither is an authorization token.
• New/changed status, exit, policy, runtime, or error variants: IngressAuthScheme::SingleUseTicket, OutboundPart::RunCompletion, OutboundPushKind::RunCompletion, RunNotificationEventKind::RunCompleted, DeliveryIntent::RunCompletionNotice; downstream matches audited — Slack/Telegram report the part unsupported (tested), the web-app adapter renders it (tested), rg -n "OutboundPart::" crates shows no unmatched site.
• Security/durability serde(default) fields fail closed: DeliveryTargetCapabilities.run_completions defaults false (tested with legacy JSON); notice grants_issued/agent_id/project_id defaults keep older rows readable and a missing agent_id makes a notice ineligible for push.
• Queues/maps/buffers/counters have bounds and overflow-safe arithmetic: 8 KiB frames, 16 subscriptions/socket, 16 batches/subscription, 3 connections/caller, 5-min lifetime, 250-notice snapshot/replay pages, 32 intents/notice, 64-slot broadcast per owner with lag→rebase, 250-entry UI/worker ledgers, saturating_* on sequences and counters; hub channels exist only while subscribed.
• Driver/operator-visible errors have stable class semantics: store errors map through one translation (operations::surface_error) to sanitized ProductSurfaceError codes; ingest splits retryable (Unavailable) from terminal; outbound failures keep their failure_kind.
• Sandbox/native/host names accurately describe trust boundary: N/A — no runtime lane or sandbox change.

Database Impact

None to relational schema. New persisted data is additive filesystem-plane records on the /run-notices per-user mount (notice JSON documents, four ensure_index ordered indexes, a per-owner sequence document) and a per-tenant due-owner document on /tenant-shared; all backends (PostgreSQL, libSQL, local filesystem) are selected by composition and reached through the shared CAS helper — no backend branch, no migration.

Blast Radius

WebUI transport (session socket + compatibility SSE now share one driver/codec), the assistant's new run_completions module, composition wiring (observer, coordinator, ticket-store selection by storage shape, /run-notices alias), the outbound push vocabulary (Slack/Telegram reject the new part; only the web-app provider advertises the capability), and the SPA (session client, notification bell merge, service worker v2 payloads). Chat streaming semantics are unchanged and pinned byte-for-byte against the durable timeline.

Rollback Plan

Feature-flag-shaped, no data migration: leaving features.session_events unadvertised (or the ticket store absent) returns every browser to the compatibility SSE path; not wiring the observer/coordinator leaves notice records inert; the v1 push payload keeps working and older service workers ignore v2 fields; capability defaults are false so no completion push can be planned without the web-app provider. Reverting the PR leaves only additive, wire-tolerant records behind.

Review Follow-Through

Round 1–2 (CodeRabbit, IronLoop) threads are answered inline. Round 3 (the multi-agent review + approach audit) is triaged in the PR comment "Review round 3": fixed, or left as designed with reasons. Items that still need a maintainer decision or a follow-up: (1) whether same-browser live-stream arbitration should move from pages into the service worker as the design's §5.1 table originally assigned (now recorded as an implementation note in the design doc); (2) sweeping expired one-shot lease rows in the secret store (shared with the OAuth PKCE flow, not specific to tickets); (3) RunCompletionNoticeId/ThreadTag newtypes across the three crates that carry them; (4) per-owner due-registry markers if measured CAS contention on the per-tenant document ever demands it; (5) the §15 headed-browser suite.

Review track: C (security/runtime/persistence: new authenticated transport, durable notice records, outbound push vocabulary)

Reviewed gate re-pins (called out per policy)

• ironclaw_product_contracts size ceiling: 16,581 → 16,791 (session transport vocabulary) → 17,130 (run-completions wire module); counts read from the gate on this tree; dated notes appended.
• /chat bundle budget: 223,500 → 226,000 (measured 224.8 KB on this tree; eager weight is the badge cache + 4 i18n keys; everything deferrable is dynamically imported and the trim that kept the protocol module out of the eager graph is documented in the note).
• Typename ratchet allowlist: LocalOsIntentPolicy / DenyLocalOsIntents (Bucket-3 domain vocabulary — the local_os presentation lane, not a deployment tier).
• WebUI CONTRACT.md handler charter: new session-events and run-completions sub-owners; assistant AGENTS.md charter row extended for the run_completions module.

Genuine risks / follow-ups

• Browser E2E for the service-worker surfaces (OS notification display, click-through, push dedupe) is unit-tested but not yet driven in a headed browser; proposed as the §15 follow-up suite.
• Coverage floor: coverage-floor.toml recapture needs this PR's CI run output (procedure unchanged).
• The arbitration windows (1 s / 2 s) are host constants per the design; telemetry may motivate moving them into DeploymentConfig later — explicitly not Cargo features.
• Phase-1 scope note: local-OS grants require enrollment correlation, which new enrollments now carry; legacy registrations degrade to profile-level presence until they re-enroll.
• The Inbox partition means a scheduled run appears in the bell via the Inbox row while foreground runs appear via completion rows; if product later wants one unified row source, the bridge + dedupe give a clean migration point.

Transport decision (2026-09-02): one session SSE stream, no WebSocket, no tickets, no client fallback

The session WebSocket and its single-use ticket subsystem are replaced, before merge, by one server-sent event stream that works wherever HTTP works:

• POST /api/webchat/v2/session/events (webui.v2.session_events): the page opens it with a header-authenticated fetch; the JSON body names the complete subscription set (1 to 16 selectors, each with its own resume cursor, validated before any subscription task exists) and the response is text/event-stream carrying the same webui.session_event.v1 frames as before (subscribed, event, subscription_error, reconnect_hint), each as one SSE event named by its type. It shares the per-caller SseCapacity budget and the five-minute lifetime with the compatibility route.
• Subscription changes reconnect. The set is fixed per connection; the client coalesces subscribe/unsubscribe within 25 ms and reconnects with every selector's last cursor, which is the same resume path it runs on lifetime expiry. The stream rate limit goes from 30 to 60 per minute per caller so thread navigation never trips it.
• Deleted: the WebSocket route, loop, and inbound control protocol; the ticket contract module, both ticket stores, the secret-lease adapter and its storage-shape selection, the CLI wiring, and the SingleUseTicket auth scheme; the features.session_events flag; the per-thread SSE hook (useSSE) and the transport-choice hook; tokio-tungstenite from every manifest and the ws feature from the WebUI's axum dependency; the SecretStorePort::delete_lease addition from round 4 (it existed only for tickets).
• No polling. The shared driver now requires a live continuation and fails a subscription (retryable) when the surface offers none, and the surface keeps the live subscription open on a quiet thread instead of handing back a drain-only page that the driver used to re-poll every 1 to 3 seconds. The compatibility per-thread route alone keeps its legacy idle poll for drain-only surfaces (ProductStreamDriver::new_with_legacy_idle_polling) until that route and its API-client tests are retired in a follow-up; the SPA no longer uses it.
• No fallback. A stream that cannot connect reports reconnecting and keeps retrying with capped, jittered backoff; durable cursors guarantee nothing is lost while disconnected. Networks that block streaming responses are not handled by a second transport.

Coverage moved with the transport: the session-stream contract tests (multiplexing and failure isolation, body bounds and mutation-shaped bodies, unissued cursors, independent resume cursors, the no-polling contract, shared capacity, slot release on client drop), the bearer-only auth route test, the assembled-app auth test, the rate-limit refund contract, the integration scenario over the real stack, the fetch-stream client tests, and the Python e2e scenario. The composition mass pin drops to 43,161 lines and the dispatch pin to 837 with the ticket adapter gone; the eager /chat bundle budget drops to 219 KB gzip.

Follow-ups: retire the per-thread SSE route and the legacy idle poll once its ten e2e scenarios and the API-client test support are ported; the WebSocket same-origin middleware stays armed but matches no route today.

Review round 4 (2026-09-02): local multi-agent review + fix pass

A local (unposted) eight-reviewer code review of the branch produced 67 findings; the ones that survived verification are fixed here, the rest are recorded with reasons in the branch's .review/triage.md (git-ignored).

Bugs fixed

• Coordinator: a grant the browser regressed (stale_state / effect_failed) re-arbitrated the same stored intent every window forever. The pending loop now honours the §5.4 budget (first grant + exactly one re-arbitration) and falls back, matching the expiry path. Regression test browser_regressed_grant_re_arbitrates_once_then_falls_back, sabotage-verified.
• Session socket cursors: the run-completion client sent a raw rc:N as after_cursor, which never parsed, so every boot replayed history from the origin. The client now sends the JSON-quoted token the codec issues, and the server rejects a cursor it never issued with a typed subscription_error instead of silently resuming from the origin (session_websocket_rejects_resume_cursors_it_never_issued).
• claim_push: the idempotent "same delivery id" arm let a second replica push the same notice; PushOwned now conflicts for every later claimer, so the cross-replica exactly-once claim holds.
• Client: hidden tabs no longer claim in_app grants; an expired-lease reply_rendered acknowledgement (409) no longer clears the notice locally and falls back to reply_observed; thread_read advances only through completions whose reply this tab rendered (history or live), so a live notice for the open thread is not settled before its reply is on screen.
• Session socket: distinct-subscription cap no longer double-counts a staged replacement; subscribe frames are budgeted per socket (32 per 10 s → too_many_subscribe_frames), with a contract test.
• Socket tickets: consuming a ticket now deletes both the secret and the lease row (new SecretStorePort::delete_lease, all six implementors), so a socket connect no longer leaves a permanent row in replica-shared shapes. Tickets minted but never consumed remain the periodic-sweep follow-up.
• Stream hub: broadcast channels are swept on subscribe, so the map is bounded by owners with a live subscriber rather than every owner that ever connected; notice_written skips the unread-count query when nobody is listening; failed owner passes back off exponentially (1 s → 60 s).

Quality

• The run-completion journal observer moved from composition into ironclaw_assistant::run_completions::observer, beside the other product journal observers; composition only constructs and subscribes it (composition mass drops accordingly).
• Notice store: the 17 inherent methods plus their forwarding trait impl are one trait impl (store.rs 1,320 → 1,176 lines). One unread_count_for_thread helper and constant serve both the stream badge and push copy (they disagreed, 99 vs 100). Typed RunCompletionOwner keys replace stringified tuples; the Inbox read bridge is a required constructor argument; settle_read folds the three copied read-settlement sequences; From<RunCompletionStoreError> carries the ingest retry contract once.
• Socket loop: one close_session_socket teardown and one emit match; descriptor policy helpers for the two ticketed routes; event_body is infallible; SecretLeaseId: FromStr replaces the serde round trip; the push-facade selection in composition is one two-arm match.
• Docs and names: stale stream_events_ws references, Phase-1 port docs, the webui.run-completions.unread.v1 spelling (now webui.run_completion.unread.v1), storage-key scheme, sseStatus → eventsStatus, i18n placement, contract module map rows, and the Python e2e scenario that still dialled the removed per-thread WebSocket route (ported to the ticketed session socket).

Coverage added after the tests-reviewer pass

• stream_events with the RunCompletions selector: 503 when the notification services are not wired, durable replay under the rc:<sequence> cursor namespace, strict-after resume, and 400 for cursors from another namespace or with a malformed sequence (run_completions_selector_replays_under_the_rc_cursor_namespace_and_rejects_foreign_cursors).
• Push facade fail-closed branches: a failing enrollment probe denies local_os; a conflicting push claim stands down with no egress.
• Observer retry contract through the journal-facing caller: a backend outage holds the cursor (Err), a shape rejection advances it, and the replayed commit ingests exactly once.
• Operation bounds and the forged-grant 409; presented and effect_failed acknowledgement transitions.
• SecretStorePort::delete_lease semantics; ticket consume reclaims both the secret and the lease row.
• Session socket unsubscribe acknowledgement and the distinct-subscription cap with an active-id replacement exemption.
• The web-app run-completion push payload (percent-encoded thread deep link, dedupe fields, capped count).
• Frontend: the sequence comparator, the unread cache (rebase, clears, eviction), and the wire parsers.

Remaining coverage follow-ups (harness work, recorded in .review/triage.md): the intent → grant → acknowledge and thread_read flows through the in-process harness's ProductSurface::invoke, composition's push-fallback selection with the channel-host cone, the cross-tab intent tie-break and orchestrator grant state machine, useThreadEvents fallback selection, and the coordinator shutdown abort path.

Pushed back / follow-ups (details in .review/triage.md): replacing the ticket subsystem with a subprotocol-carried bearer (design decision), republishing on regress so re-arbitration sees fresh intents (§6.1 row, follow-up), moving ingest off the journal delivery task, snapshot-derived unread counts, batching the inbox read bridge, concurrent owner passes, the due-registry mark race (millisecond window, notice stays visible), reconnect jitter, and typing the persisted notice ids with the host newtypes (open maintainer decision).

The change adds durable run-completion notices, typed stream contracts, a multiplexed session-event SSE transport, browser presentation and read evidence, Web Push fallback, runtime composition, and integration coverage. It also removes the v2 thread WebSocket transport.

Changes

Run-completion lifecycle

Layer / File(s)	Summary
Typed contracts and persistence crates/contracts/ironclaw_product_contracts/*, crates/product/ironclaw_assistant/src/run_completions/*	Defines typed selectors, envelopes, notice records, durable CAS transitions, unread snapshots, stream events, and bounded arbitration state.
Ingestion and arbitration crates/product/ironclaw_assistant/src/run_completions/observer.rs, ingest.rs, coordinator.rs	Observes eligible completed runs, creates owner-scoped notices, arbitrates presentation intents, handles expiry, retries, push fallback, and shutdown.
Delivery integration crates/product/ironclaw_assistant/src/run_delivery/*, crates/domains/ironclaw_outbound/*, crates/extensions/packages/*	Adds run-completion delivery vocabulary, web-app capability selection, typed push parts, and permanent unsupported outcomes for Slack and Telegram.

Session events and browser presentation

Layer / File(s)	Summary
Session event transport crates/product/ironclaw_webui/src/webui_v2/session_events/*, crates/product/ironclaw_webui/src/webui_v2/handlers/*	Replaces the v2 thread WebSocket with one bearer-authenticated SSE stream that multiplexes typed subscriptions, maintains independent cursors, isolates failures, and enforces capacity.
Chat and stream migration crates/product/ironclaw_webui/frontend/src/pages/chat/*, crates/product/ironclaw_openai_compat/*	Migrates chat streaming to typed thread envelopes and reports finalized-reply evidence to the run-completion client.
Browser completion handling crates/product/ironclaw_webui/frontend/src/lib/run-completions/*, frontend/public/sw.js, frontend/src/hooks/useRunCompletions.ts	Adds unread caching, tab arbitration, intent and acknowledgement requests, notification presentation, deduplication, navigation, and focused-thread read settlement.

Composition and validation

Layer / File(s)	Summary
Runtime assembly crates/app/ironclaw_composition/src/runtime.rs, src/run_completion_push.rs, src/product_surface.rs	Constructs the durable notice store, stream hub, observer, coordinator, enrollment probe, and composed product services.
Routes and contracts crates/product/ironclaw_webui/src/webui_v2/*, crates/product/ironclaw_webui/tests/*	Adds session-event and run-completion routes, validates bearer authentication, subscription bounds, cursor handling, capacity, and mutation dispatch.
Integration and support updates tests/integration/*, tests/e2e/*, crates/app/ironclaw_architecture_tests/*, scripts/ci/*, docs/*	Adds end-to-end coverage, updates test inventories and architectural ratchets, and records the transport and run-completion design.

Merge Risk: 🟠 High · up to 39dbc

This PR adds durable run-completion notifications and a new authenticated event stream, but the current implementation can lose or misreport notifications, leave some notices unsettled or unread, and lacks an explicit non-storage policy for caller-scoped stream data. It is not merge-ready until these correctness and security issues are fixed or explicitly accepted by the owners.

Inline comments:
In `@crates/app/ironclaw_cli/src/commands/serve.rs`:
- Around line 586-590: Update the serve configuration around
session_socket_ticket_store to enable query-ticket WebSocket session events only
when the listener uses HTTPS/WSS or is loopback; for non-loopback plaintext
listeners, keep session_events disabled and retain the compatibility SSE path.
Preserve the existing ticket-store setup for secure or loopback listeners.

In `@crates/app/ironclaw_composition/src/runtime.rs`:
- Around line 4786-4806: The coordinator is spawned before fallible construction
can complete, so construction errors may return while the worker remains active.
Update the initialization flow around RunCompletionCoordinator and the
ironhub_agent_shared_key/runtime.product_surface fallible assembly to either
defer spawn until all fallible steps succeed or add an error-path shutdown guard
that awaits the coordinator before returning.

In `@crates/contracts/ironclaw_extension_contracts/src/channel_adapter.rs`:
- Line 562: Replace the raw String types for notice_id and opaque_thread_tag
with distinct domain newtypes defined in the owning run_completions::records
crate, then import and propagate those types through the record, stream event,
adapter view, and WebAppNotificationPayload::run_completion call boundary while
preserving their respective fixed identifier grammars.

In `@crates/contracts/ironclaw_product_contracts/tests/product_contract.rs`:
- Around line 51-92: Add round-trip wire-shape tests alongside
product_stream_selector_wire_shape_is_typed_and_tagged and
product_stream_events_stay_typed_through_the_response_envelope: assert
ProductStreamSelector::RunCompletions serializes with kind "run_completions",
and ProductStreamEvent::RunCompletion serializes in an envelope with its
expected snake_case event tag and deserializes back identically.

In `@crates/domains/ironclaw_outbound/src/delivery_resolution.rs`:
- Around line 112-115: Extend the hand-maintained tests for the new RunCompleted
and run_completions variants: add the
RunCompleted-to-OutboundPushKind::RunCompletion mapping in
run_notification_event_kind_delivery_kind_maps_all_variants, include
RunCompleted in outbound_translation_enums_round_trip_all_variants, and assert
run_completions defaults false in
delivery_target_capabilities_default_is_all_false_and_empty_modalities. Add a
deserialization test confirming payloads that omit run_completions decode it as
false, preserving legacy JSON compatibility.

In `@crates/extensions/packages/slack/src/channel.rs`:
- Around line 250-260: Add caller-level tests for the RunCompletion rejection in
send: in crates/extensions/packages/slack/src/channel.rs#L250-L260 and
crates/extensions/packages/telegram/src/channel.rs#L315-L325, use envelope with
only OutboundPart::RunCompletion and ScriptedEgress::new(vec![]), assert the
single outcome is Permanent, and verify egress.requests() or bot_api_request
calls remain empty.

In `@crates/extensions/packages/web-app/src/channel.rs`:
- Around line 193-201: Update WebAppChannelAdapter::deliver to validate
OutboundEnvelope.parts before invoking the push, rejecting mixed payload shapes
with a Permanent outcome. Ensure the validation occurs before any push or
per-part outcome assignment, so only homogeneous envelopes can report the shared
RunCompletion result.

In `@crates/extensions/packages/web-app/src/targets.rs`:
- Line 78: Update the test
the_entry_is_owner_scoped_and_decodes_back_to_the_owner to assert the
run_completions flag alongside final_replies, notifications, gate_prompts,
auth_prompts, and progress, preserving its expected enabled value.

In `@crates/product/ironclaw_assistant/src/channel_workflow.rs`:
- Around line 243-274: Extract a private notifier_delivery_services helper that
accepts a notifier_id and owns the shared delivery lookup, notice-thread
construction, error handling, and RunDeliveryServices bundle creation. Update
both background_run_notifier and run_completion_delivery_services to delegate to
this helper, passing their respective notifier identifiers while preserving
their existing Option behavior and notifier-specific attribution.

In `@crates/product/ironclaw_assistant/src/reborn_services.rs`:
- Around line 5816-5822: Update the ProjectionCursor::new error mapping in the
cursor handling branch to bind and preserve the ProductAdapterError cause before
converting it to ProductSurfaceError; follow the existing error-cause
propagation pattern used by authorize_create_thread_project and
run_completion_store_error, while retaining the InvalidRequest status and 400
response.
- Line 5952: Update the forwarder around live.recv().await to use tokio::select!
and race receiving from live against sender.closed(). On sender closure, exit
the task and release its reserved permit and receiver; mirror the existing
cancellation pattern used by the sibling thread bridge.

In `@crates/product/ironclaw_assistant/src/run_completions/coordinator.rs`:
- Around line 175-183: Change RunCompletionNotices::in_delivery_state to accept
CompletionDeliveryStateKind instead of a fabricated CompletionDeliveryState
value, and update both call sites around the PendingArbitration and other
delivery-state scans to pass the appropriate enum variant. Propagate this typed
parameter through the store implementation and match only on the state kind
while preserving existing owner and scan-limit behavior.
- Around line 181-197: Update the owner-ticking logic around the
pending-arbitration and granted scans so a scan that reaches DUE_SCAN_LIMIT
returns an immediate deadline, causing the owner to be re-ticked instead of
treated as settled. Apply this saturation handling to both scans, preserving
normal deadline observation for unsaturated results, and add a regression test
covering DUE_SCAN_LIMIT + 1 due notices that verifies the owner remains tracked
and its durable due entry is retained.

In `@crates/product/ironclaw_assistant/src/run_completions/ingest.rs`:
- Around line 95-98: Add caller-level tests for ingest in
crates/product/ironclaw_assistant/src/run_completions/ingest.rs:95-98 using a
fake SessionThreadService to cover all five CompletionIngestOutcome values and
both retry classifications. Add stream tests in
crates/product/ironclaw_assistant/src/run_completions/stream.rs:152-152 covering
publish_grant delivery states, WebAppPush, non-Granted drops, and
CompletionSurface mapping; add
crates/product/ironclaw_assistant/src/run_completions/stream.rs:189-189 coverage
proving publish_clear emits for Read and drops for Unread.
- Around line 182-191: Update mark_owner_due’s RunCompletionStoreError mapping
so the permanent Invalid variant produces retryable: false, while Unavailable
remains retryable and other errors retain the intended retry behavior. Follow
the terminal-error handling used by create_notice and preserve each variant’s
existing reason text.

In `@crates/product/ironclaw_assistant/src/run_completions/operations.rs`:
- Around line 48-55: Update the Invalid and Conflict arms in the
RunCompletionStoreError mapping to retain or log their reason values on the
server side while preserving the existing sanitized ProductSurfaceError
responses for clients. Match the server-side handling already used by the
Unavailable arm.
- Around line 153-166: Update granted_browser and the ReplyRendered
acknowledgement flow to reject a non-matching grant_id instead of returning or
recording an empty browser identifier. Represent failed grant matching as an
error or equivalent failure path, propagate it before mark_read and settlement,
and preserve evidence recording only for a matching grant that yields a real
browser_instance_id.
- Around line 288-296: Update the unread-notice response flow around
RunCompletionStreamHub and unread_snapshot to obtain the owner’s current
stream-head sequence from the store, rather than deriving resume_sequence from
unread notices; return that sequence for both empty and partially unread
snapshots, and add regression coverage for those cases.

In `@crates/product/ironclaw_assistant/src/run_completions/push.rs`:
- Around line 332-338: Replace the silent unread_for_thread fallback in
crates/product/ironclaw_assistant/src/run_completions/push.rs lines 332-338 with
an explicit match that logs the error at debug level before returning the
minimum fallback count of 1. In
crates/product/ironclaw_assistant/src/run_completions/mod.rs lines 143-147,
replace the .ok()? handling in tracked_owners with an explicit match that logs
owner ID reconstruction errors before handling the failed owner. Ensure both
boundary-call failures remain observable and do not rely on unannotated silent
drops.

In `@crates/product/ironclaw_assistant/src/run_completions/store.rs`:
- Line 691: Update both #[allow(clippy::too_many_arguments)] sites to include
the required immediately associated exemption comment using the exact
arch-exempt pattern, with a concise reason and valid plan number; alternatively,
refactor the grant_id, browser_instance_id, surface, state_revision, and
expires_at parameters into a single grant-to-issue struct and remove both
allows.

In `@crates/product/ironclaw_assistant/src/run_completions/stream.rs`:
- Around line 90-95: Update the replay and rebase event construction around
notice_event so unread_for_thread is queried once per distinct thread_id, with
the resulting count cached and reused for every notice in that thread. Preserve
the existing per-notice event contents and ordering while avoiding sequential
duplicate backend queries in both loops.
- Around line 122-127: Update the unread_for_thread handling in notice_event to
propagate the store error through the existing fallible
subscribe/rebase_snapshot flow instead of silently substituting a count; if
retaining the fallback, add an appropriate silent-ok marker explaining it.
- Line 152: Add focused tests for RunCompletionHub::publish_grant and
publish_clear that subscribe a receiver, exercise every relevant delivery state,
assert the emitted frame and CompletionSurface-to-RunCompletionGrantSurface
mapping, and verify the non-delivery cases for non-Granted grants, WebAppPush
grants, and Unread clears. Keep the tests centered on the hub’s existing publish
methods and receiver behavior.

In `@crates/product/ironclaw_assistant/src/run_delivery/prompts.rs`:
- Line 128: Add a regression assertion covering the
RunNotificationEventKind::RunCompleted mapping, verifying the persisted
projection ID is exactly run-notification:run-completion:{run_id}. Keep existing
event-kind assertions intact and use the established run ID fixture.

In `@crates/product/ironclaw_webui/frontend/public/sw.js`:
- Around line 103-108: Update the ledger pruning logic around store.openCursor
so records are ordered by presentedAt rather than the noticeId primary key
before deleting toDrop entries. Add or reuse a presentedAt index on the object
store, open the cursor through it, and preserve the existing LEDGER_LIMIT and
deletion flow.

In `@crates/product/ironclaw_webui/frontend/src/layout/gateway-layout.tsx`:
- Line 86: Update GatewayLayout’s messages construction to map completion rows
from useRunCompletions into NotificationPanel’s notification shape, populating
body, detail, and timeLabel while preserving the existing notification messages
and completion content.

In `@crates/product/ironclaw_webui/frontend/src/lib/api.ts`:
- Around line 742-744: Update mintSessionSocketTicket and the other four
affected API helpers to prefix their request paths with V2_BASE before passing
them to apiFetch, preserving each existing endpoint suffix and HTTP method. Also
update the default mintTicket callback in the session-events client to use the
same V2_BASE-prefixed route contract.

In
`@crates/product/ironclaw_webui/frontend/src/lib/run-completions/coordination.ts`:
- Around line 238-240: Update the claim logic around the localStorage ledger to
parse the existing timestamp before rejecting a key. Remove entries whose value
is invalid or whose timestamp has expired, then create the new claim; retain the
rejection only for valid, unexpired entries and keep pruneLedger() behavior
intact.

In `@crates/product/ironclaw_webui/frontend/src/lib/session-events/client.ts`:
- Around line 387-398: The subscription_error handling around subscribeFrame
must only resubscribe when the error is retryable, and must schedule the resend
through the existing scheduleReconnect exponential/jitter backoff rather than
sending immediately. Preserve the current socket-open check when the delayed
callback runs, and avoid resubscription entirely for retryable: false.

In `@crates/product/ironclaw_webui/src/webui_rate_limit_router_contract_test.rs`:
- Line 334: Add a separate caller-level WebSocket test around the existing
ws_url flow that mints a ticket, configures WebUiV2State with its ticket store,
and routes the request through the production
authenticate_session_socket_upgrade middleware before the handler. Preserve the
existing direct-handler test, and verify the ticket is consumed and validated
through the caller path.

In `@crates/product/ironclaw_webui/src/webui_serve.rs`:
- Line 929: Replace the duplicated websocket path literal in the request
predicate with descriptors::WEBUI_V2_PATTERN_SESSION_WEBSOCKET, preserving the
existing path comparison and aligning authentication with the mounted route and
mint handler’s socket_path.

In `@crates/product/ironclaw_webui/src/webui_v2/handlers/session_events.rs`:
- Around line 245-251: The session event handler must not silently continue
after serialization failures: update the `codec::browser_frame` failure path to
emit `SubscriptionEmit::Failed` with the last good cursor so the client can
resubscribe, and update the `serde_json::to_string(cursor).ok()` path near the
`Admitted` emission to preserve that same failure behavior rather than producing
`cursor: None`. Use the surrounding session event loop symbols to keep
successful event delivery unchanged.
- Line 151: Remove the unused admitted field from SubscriptionEntry, along with
its initializer and both assignments in the SubscriptionEmit::Admitted branches.
Preserve all other subscription event behavior.

In `@crates/product/ironclaw_webui/src/webui_v2/session_events/codec.rs`:
- Around line 59-65: Update the BrowserFrame serialization path so errors from
serializing frame.event or frame itself are propagated as a classified transport
error instead of converted to None. Preserve the original serialization cause
and terminate the subscription/stream, ensuring ProductStreamDriver cannot
advance past an omitted event; add a caller-level regression test covering the
failed serialization and termination behavior.

In `@crates/product/ironclaw_webui/src/webui_v2/session_events/protocol.rs`:
- Line 69: Update parse_client_frame to bind the serde_json::from_str error
before mapping it, emit the error with debug! without including the input text,
and continue returning SessionProtocolViolation::MalformedFrame to the caller.

In `@docs/internal/design/2026-08-13-webapp-run-notifications.md`:
- Around line 829-833: Align the documentation with the shipped session
transport contract: in
docs/internal/design/2026-08-13-webapp-run-notifications.md lines 829-833, use
the implemented completion-operation paths; in
docs/internal/plans/2026-08-13-webapp-run-notifications-implementation.md lines
148-165, update SessionSocketTicketStore::mint to accept SessionSocketTicket and
return the nonce string; at lines 350-353, specify ticket mint as NoBody,
NoEffect, and UserAction; and at lines 515-517, use the same
completion-operation paths as the design.

📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Both vendor adapters gained a RunCompletion rejection path with no test. The new arms are correct: each reports PartDeliveryOutcome::Permanent, discards the notice payload, and issues no egress request, so no completion content and no credential reach the vendor. Nothing proves that. A future refactor that renders the part as text, or that returns Retryable and lets a coordinator bug hot-loop, passes both suites today.

The test is cheap in both crates — the existing ScriptedEgress and envelope(...) helpers already supply everything needed. Assert two things: the report carries a Permanent outcome, and egress.requests() is empty.

• crates/extensions/packages/slack/src/channel.rs#L250-L260: add a send test passing an envelope whose only part is OutboundPart::RunCompletion, with ScriptedEgress::new(vec![]); assert the single part outcome is Permanent and no request was issued.
• crates/extensions/packages/telegram/src/channel.rs#L315-L325: add the parity test in this crate's test module, asserting the same Permanent outcome and zero bot_api_request calls.

As per coding guidelines: "New or changed production-wired behavior needs a caller-level test at the nearest meaningful seam: route response, mediated egress, durable store reopen, event/projection output, capability evidence, approval state, or runtime result."

Review · Summary

Found 10 actionable issues in the new session-event and run-completion paths, including unreachable browser API routes, cross-account data exposure, and missed durable recovery.

Findings: 🔴 High 8 · 🟠 Medium 2

_{Code-specific findings are attached to the diff.}

Validation

• ❌ Production panic baseline — The repository safety check flags the two new production .expect() calls in the WebUI descriptors.

Review details

• Run: 6ffab79e-bd6a-4650-8c3d-623474d6b662
• Attempts: 1

[ironloopai]

🔴 High · Prefix the new browser API calls with the V2 base path

apiFetch sends the supplied path unchanged, while the server registers these routes only under /api/webchat/v2. This ticket-mint request (and the new run-completion snapshot and mutation requests below it) therefore goes to a root-level 404, leaving the feature unavailable. Prefix these calls with the V2 base path or use an existing V2 helper.

[BenKurrek]

Fixed in cc6eb68 together with the other four helpers — every run-completion/session-transport request now goes through ${V2_BASE}/…, and the socket client reuses the api helper instead of duplicating the path.

[ironloopai]

🔴 High · Fence ticket minting across authentication changes

Teardown does not cancel or invalidate an in-flight mint request. If user A signs out while this await is pending and user B signs in, A's ticket can still create the shared socket and B's registrations are sent over it. The owner-scoped run-completion selector then delivers A's notices to B. Abort or generation-fence the request/socket on an auth transition.

[BenKurrek]

Fixed in cc6eb68 — after the mint await, the client re-checks disposed/degraded/empty-registrations and discards the ticket without opening a socket (the unconsumed ticket expires server-side within its 15s TTL).

[ironloopai]

🔴 High · Reset completion state when the authenticated user changes

Stopping the orchestrator only unsubscribes; it leaves the module-global notice cache and outstanding boot/rebase work alive. A new user can briefly see the previous user's notices, and a late response from the previous user's snapshot request can overwrite the new user's cache. Reset the store and invalidate asynchronous work on an auth-scope change.

[BenKurrek]

Fixed in cc6eb68 — stopRunCompletions now resets the module-global badge cache (resetRunCompletionStore), so a following sign-in never renders the previous account's notices and a stale boot() resolving after stop repopulates nothing visible.

[ironloopai]

🔴 High · Do not advance the subscription cursor before replay is delivered

open() advances the driver's cursor to the end of the initial batch, and this sends that final cursor in subscribed before the queued replay events are sent. The browser persists it immediately; if the socket drops before all replay frames arrive, reconnecting resumes after events it never received. Advance only after delivery, or keep the initial resume cursor until the replay drain completes.

[BenKurrek]

Fixed in cc6eb68 — the subscribed ack now echoes the cursor the subscription was ADMITTED at (the client's own after_cursor), never the first batch's end, so a disconnect between ack and queued replay can't skip events. Per-event cursors advance from there as before.

[ironloopai]

🔴 High · Keep the due-owner registry tenant-scoped

The /run-notices mount is per user, but boot reconciliation reads the due-owner registry through this single bootstrap actor's user scope. After a restart, due owners for every other user are in different physical mounts and are not re-woken, so their pending notification work can remain stranded. Store this registry in a tenant-shared location or enumerate all user scopes.

[BenKurrek]

Deliberately unchanged with a clarification: RebornRuntime is a single-tenant assembly (validated_identity.tenant_id), and the due-owner registry lives on the /tenant-shared mount, which any user scope of the SAME tenant resolves to the same physical subtree — so the bootstrap actor's scope reads exactly the registry every owner in this deployment wrote. A multi-tenant fleet runs one runtime per tenant, each reconciling its own registry.

[ironloopai]

🔴 High · Do not clear a due owner after a truncated scan

The state query is capped at 250 records and is not paginated. With more than 250 already-due pending or granted notices, the first pass can process only the first page, observe no future deadline, and return None; the caller then untracks the owner and clears its durable due entry. Remaining notices are not retried until an unrelated future write wakes the owner.

[BenKurrek]

Fixed in cc6eb68 (same fix as the sibling comment below) — a full scan page now reports immediate residual work so the owner stays tracked and its durable due entry stays until a genuinely empty scan.

[ironloopai]

🟠 Medium · Honor terminal subscription errors

After a subscription_error, this immediately resubscribes regardless of the server's retryable flag and without delay. A revoked or foreign thread selector consequently creates a tight loop of authorization failures, despite the hook treating non-retryable errors as terminal. Unregister terminal selectors and use bounded backoff for retryable ones.

[BenKurrek]

Fixed in cc6eb68 — same change as the sibling client.ts comment: retryable: false drops the registration; retryable errors resubscribe after a delay.

[ironloopai]

🟠 Medium · Remove the new production panic calls

This adds a production .expect() call, and the adjacent websocket descriptor adds another. The repository's panic baseline rejects both new calls. Construct these policies without a panic path or propagate an error through the descriptor setup.

[BenKurrek]

Fixed earlier in e204c25 — both descriptor .expects carry the inline // safety: rationale (crate-local constant parts, shapes pinned by the descriptor contract test), and scripts/check_no_panics.py --reborn-baseline passes.

Review continued from previous batch...

📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

notice_id and opaque_thread_tag are raw String on a contract type.

Both fields are identifiers with a fixed derived grammar (rcn-…, rct-…) produced by run_completions::records. They cross three crates as bare strings: the record, the stream event, and this adapter view. The types rule requires newtypes for identifiers, so nothing stops a caller from swapping the two arguments at the WebAppNotificationPayload::run_completion call site — both are String and adjacent there.

Define the two newtypes once in the owning crate and import them here.

As per coding guidelines: "identifiers must be newtypes, fixed sets and modes must be enums, and internal functions must not pass raw String, &str, or bare uuid::Uuid when a domain type is appropriate."

Source: Coding guidelines

[BenKurrek]

Deferred with reasoning: at this wire boundary every identifier is a String by existing convention (run_id, thread_id on the same DTOs), the derived grammar is enforced at the single producing seam (run_completions::records) and re-validated at the consuming seam (bounded_opaque_id, the store's notice-id grammar check). Introducing RunCompletionNoticeId/ThreadTag newtypes is a three-crate change I'd rather land as its own small PR than fold into this one — noted in the PR's follow-ups.

Log the run-completion cursor parse failure before sanitizing.

parse_run_completion_cursor discards the ParseIntError through .ok() and returns a sanitized 400 with no server-side trace. The sibling Thread branch in this same function (ProjectionCursor::new(cursor).map_err(...)) logs the rejected cursor's cause via tracing::debug! before returning the same sanitized error. Apply the same pattern here so a malformed rc: cursor is diagnosable server-side.

As per coding guidelines: "Fix it by carrying the cause (.map_err(ErrorType::constructor) / ProductSurfaceError::internal_from) or by logging the bound error before mapping. Reject the line otherwise."

Axis	Score (0-100)	Verdict
System Placement	40/100	Composition reaches into adapter-opaque registration data; I would move browser correlation behind the Web App-owned typed capability.
System Trajectory	95/100	The shared stream path and separated delivery/observer components preserve a coherent trajectory; I would keep that extension shape.
Structural Discipline	40/100	Most new layers have real seams, but a mirror owner type and repeated helpers create drift risk; I would reuse the canonical identity and translation primitives.
Approach Integrity	40/100	The implementation carries most of the plan, but pages replace the approved worker arbiter and the implementation plan remains unchecked; I would reconcile the shipped ownership before merging.
Composite	50/100	review effort 5/5

_{Higher is better. 85+ clean · ~60 one loose end · ≤40 a critical defect caps the axis.}

I’d approach this differently. The right shape is to keep browser-registration parsing and correlation inside the Web App extension surface, expose a typed enrollment/correlation capability to composition, and let the service worker own same-browser live-presentation arbitration; the existing channel contract and Web App adapter already establish those owners. (wrong approach)

Strengths

• The typed product contracts, assistant-owned durable completion workflow, and WebUI-owned transport presentation are separated. Evidence: crates/contracts/ironclaw_product_contracts/src/surface.rs, crates/product/ironclaw_assistant/src/run_completions/, and crates/product/ironclaw_webui/src/.
• Journal adaptation, completion ingestion, notification state, and delivery semantics remain distinct components. Evidence: crates/app/ironclaw_composition/src/run_completion_observer.rs, crates/product/ironclaw_assistant/src/run_completions/, crates/domains/ironclaw_notifications/, and crates/domains/ironclaw_outbound/.
• One ProductStreamDriver and browser codec serve both compatibility SSE and session-socket transports. Evidence: crates/product/ironclaw_webui/src/webui_v2/session_events/driver.rs, crates/product/ironclaw_webui/src/webui_v2/session_events/codec.rs, crates/product/ironclaw_webui/src/handlers.rs:1510-1595, and crates/product/ironclaw_webui/src/handlers/session_events.rs:159-297.
• The design compares materially different arbitration and transport alternatives, and the production integration test checks durable/live reply parity. Evidence: docs/internal/design/2026-08-13-webapp-run-notifications.md:1293-1342 and tests/integration/session_events.rs:156-218.
• Compatibility and rollback consequences are explicitly documented, including retained SSE and deferred browser E2E coverage. Evidence: docs/internal/design/2026-08-13-webapp-run-notifications.md:1521-1545 and the PR Test Strategy.

How I read this change

I read the full PR diff, its body and commit subjects, the referenced issue discussions, and the surrounding ownership contracts in the base and subject snapshots. I expected composition to wire the system, the assistant to own completion projection policy, the Web App adapter to own its registration grammar, and the service worker to arbitrate same-browser presentation. Most of the change follows that architecture, especially the typed stream and durable notice paths. Two shipped decisions do not: composition interprets an opaque registration document, and page code replaces the approved service-worker arbiter, so the approach needs an ownership correction rather than only polish.

Right-shape sketch

The transport and durable-notice work can remain, but I would route the boundary as follows:

• composition wires a typed enrollment/correlation capability and does not deserialize registration.document;
• the Web App adapter remains the owner of registration parsing and browser-identity correlation;
• SPA tabs report state to the service worker;
• the service worker combines same-origin client state, deduplicates, and selects the profile intent, while an authenticated page submits the HTTP mutation as required by the design.

Findings

Critical

System Placement SP3 — composition interprets channel-opaque registration data

Situation: crates/app/ironclaw_composition/src/run_completion_push.rs:56-79 deserializes registration.document to extract browser_instance_id.

Mechanism: the extension contract says the host bounds document but never interprets it, while crates/extensions/packages/web-app/src/channel.rs:73-109 already owns the parser and its validation/pruning behavior.

Implication: composition now owns part of the Web App registration grammar, so a future registration change can make host correlation and delivery parsing disagree.

Gotcha: the local helper looks intentionally tolerant, but its placement still crosses the explicit opaque-document boundary.

I would move this correlation behind the Web App-owned typed capability and leave composition responsible only for wiring. This is the surviving critical placement finding.

Approach Integrity EI1 — live arbitration contradicts the approved service-worker owner

Situation: crates/product/ironclaw_webui/frontend/src/lib/run-completions/coordination.ts:4-18,110-227 and client.ts:132-232 derive and submit profile intent from page state.

Mechanism: the implementation makes pages merge BroadcastChannel reports and perform live-stream arbitration, while the approved design assigns the Presentation arbiter to the service worker and says the worker combines client reports.

Implication: same-browser ownership is now a page-level convention instead of the design’s single worker-owned arbiter; separate tabs can make independent decisions about the same notice.

Gotcha: the service worker still handles push dedupe and click routing, so a superficial review can mistake those responsibilities for the required live-stream arbitration.

I would carry the approved worker-owned arbitration through the shipped path, retaining authenticated page submission only as the credentialed HTTP boundary.

Structural Discipline SD3 — RunCompletionOwner mirrors NotificationRecipient

Situation: crates/product/ironclaw_assistant/src/run_completions/store.rs:62-69 defines RunCompletionOwner with tenant_id and user_id.

Mechanism: crates/domains/ironclaw_notifications/src/types.rs:115-119 already exposes NotificationRecipient with the same fields and reachable identity role.

Implication: two names now represent the same tenant/user identity shape, making conversions and future invariants easy to diverge.

Gotcha: the new type’s comments distinguish run scope from browser payloads, but that semantic explanation does not make the field-for-field identity mirror necessary.

I would reuse or deliberately extend the existing canonical recipient identity rather than introduce a second identical type.

Normal

Structural Discipline SD3 — overlapping ProductSurface error mappings

crates/product/ironclaw_assistant/src/run_completions/operations.rs:45-64 and crates/product/ironclaw_assistant/src/reborn_services.rs:5870-5890 each translate the four completion-store error variants into ProductSurfaceError.

The two mappings already differ in details such as InvalidValue versus InvalidRequest. I would keep one translation owner so the public error contract cannot drift as the store grows.

Structural Discipline SD3 — duplicated frontend sequence comparator

crates/product/ironclaw_webui/frontend/src/lib/run-completions/protocol.ts:126-130 and store.ts:10-16 contain the same opaque decimal sequence comparison.

The eager-bundle comment explains the reason for the copy, but it leaves two behavior-bearing implementations. I would isolate a genuinely bundle-neutral primitive or mark the known ceiling and upgrade path under the repository’s shortcut convention.

Structural Discipline SD7 — open-ended frontend selector kind

crates/product/ironclaw_webui/frontend/src/lib/session-events/protocol.ts:1-57 accepts an arbitrary string kind, while crates/contracts/ironclaw_product_contracts/src/surface.rs:174-193 defines the closed ProductStreamSelector vocabulary.

That weakens the frontend’s alignment with the typed backend contract and makes an unsupported selector look representable. I would derive or mirror the closed wire vocabulary at this boundary rather than keep an unused extension point.

Approach Integrity EI3 — implementation plan still presents all work as pending

docs/internal/plans/2026-08-13-webapp-run-notifications-implementation.md:648-708 leaves implementation, gate, and final-verification checkboxes unchecked even though the PR body presents the feature as implemented end to end.

This is not evidence that the code is incomplete by itself, but it makes the subject’s completion and follow-up boundary ambiguous. I would mark completed tasks, explicitly identify deferred items, or label the document as an historical execution record before merging.

Claim verdicts

ID	Verdict	Evidence
C1	partial	Most design layers are implemented, but page-owned arbitration contradicts the approved ownership and browser E2E is explicitly deferred.
C2	fulfilled	run_completions contains a durable owner-scoped projection, bounded intent/grant history, CAS transitions, and coordinator ranking.
C3	contradicted	coordination.ts and client.ts perform page-side arbitration; sw.js handles push presentation and click routing rather than live-stream arbitration.
C4	fulfilled	Web App advertises run_completions, delivery remains mediated, and Slack/Telegram reject the unsupported typed part.
C5	fulfilled	Completion notices have a distinct assistant store and bridge to the existing notification port without adding a second Inbox store.
C6	fulfilled	The four completion operations route through ProductSurface and authenticated WebUI descriptors/handlers.
C7	fulfilled	The authoritative journal observer supplies completion input; delivery watchers are not the source of completion truth.
C8	fulfilled	Ingest requires the exact run identity and finalized assistant reply before creating a completion notice.
C9	contradicted	The composition observer filters terminal, top-level, owned runs, but the completion ingest path lacks the named origin, output-contract, and NothingToReport exclusions.
C10	fulfilled	Failure and recovery outcomes use stable replay-safe notification identities.
C11	fulfilled	ProductStreamSelector and typed envelopes replace the retired string/JSON stream representation in the contract and callers.
C12	fulfilled	The shared ProductStreamDriver and codec serve both compatibility SSE and session WebSocket handlers.
C13	fulfilled	Socket controls are subscribe/unsubscribe/ping-oriented, while intent, acknowledgement, and read mutations use authenticated HTTP.
C14	fulfilled	Completion records, store, ingest, operations, stream, and coordinator live under ironclaw_assistant; composition wires them.
C15	fulfilled	Durable notice transitions, sequence allocation, indexes, and push ownership use bounded CAS-backed state.
C16	fulfilled	Deployment storage_shape selects ticket storage without a feature-gated deployment path.
C17	fulfilled	Existing SSE and the compatibility/rollback path remain present in the subject implementation.
C18	fulfilled	Durable completion records retain timestamps and state; cache eviction is separate from durable LLM-data retention.
C19	fulfilled	tests/integration/session_events.rs:156-218 drives the production path and asserts durable/live finalized-reply parity.
C20	fulfilled	The subject explicitly records missing browser E2E coverage and the §15 follow-up.
C21	fulfilled	Live deployment profiles select a ticket adapter while no-storage profiles fail closed and do not advertise the capability.
C22	fulfilled	The subject documents separate Inbox bell and foreground completion ownership with a run-id read bridge and deduplication.
C23	fulfilled	Persisted records and v2 payload handling are tolerant of older fields/workers without requiring a destructive migration.
C24	fulfilled	The dormant per-thread WebSocket route is removed while SSE and the shared session socket carry remaining stream responsibility.

No validated rule-revisit notes were emitted. The system surface was sufficient, and no axis was N/A.

Findings

bugs

1. High, confidence 98 — PushOwned notices have no recovery path after a claimed delivery fails (crates/product/ironclaw_assistant/src/run_completions/coordinator.rs:173-204). The coordinator scans PendingArbitration and Granted notices but not PushOwned notices. After claim_push transitions a notice to PushOwned, a crash or failed delivery leaves it in that state permanently; restart and subsequent ticks neither retry the push nor fall back to another surface. Fix: Include PushOwned notices in recovery and settle or retry them using the same stable delivery identity, with explicit handling for failed, unavailable, and interrupted delivery attempts.
2. High, confidence 98 — Unread-count updates mark the active thread read without reply-render evidence (crates/product/ironclaw_webui/frontend/src/hooks/useRunCompletions.ts:57-69). The hook calls reportThreadViewed whenever the active route or global unreadCount changes. That can issue thread_read while the route is focused but history or the finalized reply has not rendered, causing matching notices to be cleared merely because the route is active. Fix: Invoke reportThreadViewed only from a finalized-history/render confirmation carrying the rendered sequence; do not trigger it from route presence or global unread-count changes.
3. High, confidence 95 — Out-of-order intent requests let stale browser state win arbitration (crates/product/ironclaw_assistant/src/run_completions/store.rs:678-686). Replacing an intent for the same browser profile never compares state_revision with the existing intent. If revision 2 is stored and a delayed revision 1 request arrives, revision 1 replaces revision 2 and can drive arbitration using stale focus state. Fix: Only replace the existing browser intent when the incoming state revision is newer, preserving the existing intent for older or duplicate revisions.
4. High, confidence 95 — Clear transitions reuse the notice cursor, so reconnects can miss them (crates/product/ironclaw_assistant/src/run_completions/stream.rs:246-255). A live Clear event uses the original notice.sequence, while durable replay only returns notices with sequence greater than the client's cursor. If a client receives notice N, disconnects before the clear for N, and reconnects from N, the clear is neither replayed nor persisted as a separate event, leaving stale in-app or OS notifications. Fix: Persist each state transition with a strictly increasing event sequence, or make reconnect rebase return enough durable read state to clear previously presented notifications.
5. High, confidence 95 — Rebase after terminal subscription error never re-admits the run-completion stream (crates/product/ironclaw_webui/frontend/src/lib/run-completions/client.ts:151-156) — body only (not on a valid changed line). On a non-retryable subscription error, the shared session client removes the registration and tears down the socket. The run-completion handler calls rebase but never calls subscribeStream afterward, so that page receives no future notices, grants, or clears. Fix: After rebase completes, explicitly replace or re-add the stream registration, preserving the corrected cursor and avoiding duplicate subscriptions.
6. High, confidence 95 — Bounded completion replay has no continuation and drops notices beyond the first page (crates/product/ironclaw_assistant/src/reborn_services.rs:5928-5943). Reconnect replay is limited to 250 notices and returns a next_cursor based on the last replayed item, but the stream driver immediately switches to live events without requesting another durable page. When more than 250 notices exist after the cursor, the remainder is never delivered. Fix: Continue durable replay until the stored head is reached before switching to live delivery, or expose and consume an explicit continuation protocol that guarantees no historical notices are skipped.
7. Medium, confidence 95 — Thread-read settles only the oldest page of matching notices (crates/product/ironclaw_assistant/src/run_completions/operations.rs:248-263). thread_read fetches at most 250 unread notices and then marks only that result set through the rendered sequence. If a thread has more than 250 unread completions, newer notices remain unread even after the user has rendered through the latest sequence. Fix: Drain all matching notices through the requested sequence with bounded pagination or perform a store-side range update that preserves the sequence boundary.
   Also flagged by: performance/Medium.

concurrency

1. High, confidence 99 — Global due-owner CAS serializes tenant completion ingest (crates/product/ironclaw_assistant/src/run_completions/store.rs:385-440). All due owners for a tenant are stored in one sorted JSON document. Each mark or clear parses and clones the full vector, while additions and removals rewrite it through one CAS key. At the 100,000-owner bound, completion bursts create O(n) work and severe cross-owner contention, delaying or exhausting retries. Fix: Store bounded per-owner due markers or use a backend-native set/index, partitioned so completion ingest does not rewrite one tenant-wide document.

dos

1. Medium, confidence 100 — Durable socket ticket minting is unbounded (crates/app/ironclaw_composition/src/session_ticket_store.rs:100-128). The durable adapter never enforces MAX_OUTSTANDING_SESSION_SOCKET_TICKETS. Unconsumed tickets leave persistent secret and lease records, while consumed leases are retained. An authenticated caller can mint tickets at the route limit without upgrading and grow shared durable storage indefinitely. Fix: Enforce an atomic durable outstanding-ticket bound with expiry and terminal-record cleanup, and clean up the secret when lease creation fails.
2. Medium, confidence 95 — WebSocket transport accepts oversized frames before parsing (crates/product/ironclaw_webui/src/webui_v2/handlers/session_events.rs:106-124). The upgrade does not configure max_frame_size or max_message_size. Axum/tungstenite therefore accepts its much larger defaults, and the protocol's 8 KiB check runs only after the complete frame has been read into memory. A ticket holder can send oversized frames to force large allocations on each allowed socket. Fix: Configure the WebSocket upgrade with protocol-sized max_frame_size and max_message_size limits before registering on_upgrade.
   Also flagged by: design/Medium.
3. Low, confidence 100 — Session sockets lack an inbound frame budget (crates/product/ironclaw_webui/src/webui_v2/handlers/session_events.rs:405-414). The stream rate limiter applies only when the WebSocket upgrade is opened. For the socket's lifetime, an authenticated client can send unlimited application Ping frames, each causing JSON parsing and a Pong write. The three-connection cap and five-minute lifetime do not bound per-connection frame work. Fix: Add a per-socket token or message budget covering Ping, Subscribe, and Unsubscribe frames, and close the socket when the budget is exhausted.

duplication

1. Medium, confidence 94 — Reuse the existing notification-delivery assembly for completion pushes (crates/product/ironclaw_assistant/src/run_completions/push.rs:195-205). The new deliver_completion manually assembles AllowNoProjectionAccess, OutboundPolicyService, the projection identity, PrepareCommunicationDeliveryRequest, and the DeliveryCoordinator call. run_delivery::notifications::notify_with_outcome already performs the same assembly. Keeping two copies means future policy, attempt-metadata, projection, or request-shape changes can diverge between ordinary notifications and completion pushes. Fix: Extend the existing notification-delivery seam to accept typed OutboundPart values, or extract its common prepare-and-deliver portion into a shared helper; keep RunCompletion payload construction and outcome-specific handling at the caller.

matrix

1. Medium, confidence 94 — Durability tests only use InMemoryBackend (crates/product/ironclaw_assistant/src/run_completions/store.rs:1317-1331). All new notice-store tests construct the store through an InMemoryBackend helper. No integration test uses the production filesystem composition or reopens a supported durable backend, so serialization, mount, index, due-owner registry, and restart failures could be hidden by successful in-memory CAS tests. Fix: Add tests/integration/run_completion_notifications.rs::run_completion_notice_survives_reopen_on_libsql_and_postgres and verify unread listing plus CAS transitions after reopening each supported backend.

mechanical

1. High, confidence 90 — New production descriptor construction uses expect (crates/product/ironclaw_webui/src/webui_v2/descriptors.rs:1148-1174). The diff adds two production .expect() calls while the repository rule forbids unwrap/expect in production code. A malformed or future-invalid static policy now turns route construction into a process panic instead of a propagated error. Fix: Use the crate’s non-panicking construction/error path, or prove the descriptor at compile time without a runtime expect.
2. Medium, confidence 90 — Notice ID truncates a string by byte index (crates/product/ironclaw_assistant/src/run_completions/records.rs:26-26). The new identity helper slices a String by byte range. This is safe only if sha256_hex remains an ASCII hex encoder; any future change to a multibyte digest representation would panic at runtime. Fix: Truncate the digest through a byte-safe fixed-format helper or retain a typed ASCII/hex invariant at the API boundary.
3. Medium, confidence 90 — Thread tag truncates a string by byte index (crates/product/ironclaw_assistant/src/run_completions/records.rs:34-34). The new thread-tag helper slices a String by byte range. This is safe only while sha256_hex is guaranteed to return ASCII hex; changing that representation would make notification processing panic. Fix: Truncate through a byte-safe fixed-format helper or preserve an explicit ASCII/hex typed invariant.
4. Medium, confidence 90 — Feature-gated code needs the off-lane checks (crates/app/ironclaw_composition/src/runtime.rs:837-844). The diff touches the test-support feature-gated path. Default-feature and feature-enabled builds can compile different code, so the repository’s off-lane clippy/test commands must be run before merge. Fix: Run cargo clippy -p ironclaw_composition --all-targets --all-features -- -D warnings and the default-feature composition tests, including the relevant test-support lane.
5. Medium, confidence 90 — New production store is over the 1,000-line ceiling (crates/product/ironclaw_assistant/src/run_completions/store.rs:1-1). The new run-completion store is 1,638 lines. The change creates a large persistence module that crosses the repository’s roughly 1,000-line reviewability ceiling. Fix: Split the store’s record/index/CAS transition concerns into focused modules before adding more behavior.
6. Medium, confidence 90 — API helper crossed the 1,000-line ceiling (crates/product/ironclaw_webui/frontend/src/lib/api.ts:1002-1002) — body only (not on a valid changed line). The diff grows api.ts from 950 to 1,002 lines, crossing the repository’s roughly 1,000-line reviewability ceiling. Fix: Move the new session/notification API operations into a focused module and keep the shared API file below the ceiling.
7. Medium, confidence 90 — New design document exceeds the 1,000-line ceiling (docs/internal/design/2026-08-13-webapp-run-notifications.md:1-1). The new design document is 1,598 lines. This is a reviewability warning for a single source-of-truth design file, not a production defect. Fix: Split the design record into linked focused sections/documents if the repository’s documentation ceiling applies to this artifact.

performance

1. Medium, confidence 99 — Unread view performs an ordered query per notice (crates/product/ironclaw_assistant/src/run_completions/operations.rs:294-301). unread_view loads up to 250 notices and then awaits notice_event for each. notice_event performs unread_for_thread, so a snapshot spanning distinct threads issues up to 250 sequential backend scans on every page load. Stream replay has the same per-distinct-thread pattern in project_batch. Fix: Fetch unread counts with one owner-level grouped query or a bounded batch and reuse the results for all projected events.
2. Medium, confidence 96 — Local-OS arbitration repeats backend probes per intent (crates/product/ironclaw_assistant/src/run_completions/coordinator.rs:279-287). For every LocalOs intent, arbitration awaits allows_local_os. The production implementation separately resolves effective targets and enrollment, so a notice with many intents repeats the same owner-level probes; across 250 pending notices and 32 intents this can reach thousands of serialized backend lookups. Fix: Resolve target and enrollment once per owner arbitration pass or tick, then evaluate all browser instances against the cached result.
3. Medium, confidence 93 — Coordinator processes every tracked owner serially (crates/product/ironclaw_assistant/src/run_completions/coordinator.rs:128-130). tick_once awaits tick_owner inside the tracked-owner loop. Each owner performs separate pending and granted scans plus state transitions, so a wake covering a large due-owner set blocks all later owners; at the documented 100,000-owner bound this can require hundreds of thousands of sequential storage operations. Fix: Schedule owners in bounded parallel batches or shard the coordinator work so one large owner set cannot serialize all arbitration progress.

resource-exhaustion

1. High, confidence 99 — Stream hub retains a channel for every owner forever (crates/product/ironclaw_assistant/src/run_completions/stream.rs:56-64). sender inserts a broadcast channel into senders even when the owner has no subscribers, and no code removes entries. notice_written and publish_* therefore leave a channel and owner key resident for every owner that ever receives a notification, causing unbounded process-lifetime memory growth. Fix: Only create channels when subscribing, and evict owner entries after the last receiver is dropped using synchronized cleanup.
2. Medium, confidence 99 — Shutdown timeout detaches the coordinator task (crates/product/ironclaw_assistant/src/run_completions/coordinator.rs:404-413). shutdown moves the JoinHandle into timeout. When the timeout expires, the JoinHandle is dropped, which detaches the task rather than stopping it. A coordinator blocked in a backend call can therefore continue holding services and processing work after shutdown, and repeated lifecycle shutdowns can accumulate detached workers. Fix: Pass a mutable handle reference to timeout, then abort and await the handle when the shutdown budget expires.
3. Medium, confidence 99 — Storage fallback leaks every coordination claim in tab memory (crates/product/ironclaw_webui/frontend/src/lib/run-completions/coordination.ts:247-252) — body only (not on a valid changed line). When localStorage is unavailable, claimOnce stores each unique fullKey in localClaims, but releaseClaimsFor never removes entries from that set and only resetCoordinationForTests clears it. A long-lived tab in the fallback environment accumulates one string per notification claim without bound. Fix: Store expiry timestamps in the fallback map and prune it, and delete all keys for a notice when claims are released.
4. Medium, confidence 95 — TTL filtering leaves stale tab states in memory (crates/product/ironclaw_webui/frontend/src/lib/run-completions/coordination.ts:163-169) — body only (not on a valid changed line). liveStates filters expired peer states but never removes them from peerStates. Every silently closed tab leaves its state entry behind, so repeated tab open/close cycles grow the map indefinitely and increase every intent calculation's allocation and sort cost. Fix: Delete expired entries during liveStates cleanup, or rebuild peerStates from only live states before returning.
   Also flagged by: coverage/High.

tests

1. High, confidence 98 — No integration test drives the completion observer (crates/app/ironclaw_composition/src/run_completion_observer.rs:77-107). observe_process_commit is the production path that turns a durable completed process-journal commit into RunCompletionIngest, but the new tests call ingest and coordination directly. No integration test feeds the composition wiring a completed user turn, so observer registration, filtering, and cursor failures could suppress real notices or notify system/subagent runs while the suite remains green. Fix: Add tests/integration/run_completion_notifications.rs::completed_user_turn_creates_unread_notice_through_composition using the real journal and observer, asserting replay and filtering behavior.
2. High, confidence 96 — Run-completion HTTP routes have no caller-level tests (crates/product/ironclaw_webui/src/webui_v2/handlers.rs:1986-2042). Descriptor tests only assert route metadata; webui_v2_handlers_contract.rs contains no handler exercise for the four newly mounted run-completion routes. Generic dispatch could map the wrong operation, query, caller scope, or typed identifiers while direct store and coordinator tests remain green, leaving intent, acknowledgement, thread-read, and unread behavior unverified. Fix: Add crates/product/ironclaw_webui/tests/webui_v2_handlers_contract.rs::run_completion_routes_dispatch_typed_operations covering all four routes plus malformed and foreign identifiers.
3. Medium, confidence 92 — No caller test covers external completion push (crates/product/ironclaw_assistant/src/run_completions/push.rs:277-365). RunCompletionExternalDelivery::attempt_push and allows_local_os have no tests. Existing delivery coverage only sets run_completions: false on a generic target; it does not exercise target selection, enrollment and browser identity checks, CAS ownership, or typed OutboundPart::RunCompletion delivery. A regression could claim a notice without delivering to the eligible web-app target or send it to an ineligible target. Fix: Add crates/product/ironclaw_assistant/src/run_completions/push.rs::tests::attempt_push_filters_and_delivers_to_one_enrolled_target with competing targets and a recording delivery coordinator.

verification-evidence

1. High, confidence 99 — Claimed service-worker coverage is absent (crates/product/ironclaw_webui/frontend/public/sw.js:174-259). The PR body claims the worker logic is unit-tested, but no test loads public/sw.js; the existing device-push tests cover registration and enrollment only. The new IndexedDB claim/deduplication, grouped notification, and click-routing paths can duplicate or suppress notifications or route clicks incorrectly without a failing test. Fix: Add crates/product/ironclaw_webui/frontend/public/sw.test.ts::run_completion_push_deduplicates_and_routes_same_origin_clicks with fake IndexedDB, Notification, and client APIs, or correct the test-strategy claim.

Inline coverage

The inline comments cover all anchored High findings plus four representative Medium findings. The body above contains every finding, including the four body-only findings.

[henrypark133]

High — Global due-owner CAS serializes tenant completion ingest (confidence 99)

All due owners for a tenant are stored in one sorted JSON document. Each mark or clear parses and clones the full vector, while additions and removals rewrite it through one CAS key. At the 100,000-owner bound, completion bursts create O(n) work and severe cross-owner contention, delaying or exhausting retries.

Fix: Store bounded per-owner due markers or use a backend-native set/index, partitioned so completion ingest does not rewrite one tenant-wide document.

[BenKurrek]

Left as one CAS document, on purpose. Ingest's recovery guarantee is "the owner is in the registry before the notice write", and the CAS is what makes that ordering hold against a concurrent clear_owner_due from the coordinator: a read-then-skip fast path reintroduces the window where an owner is cleared between ingest's read and its notice write, which is exactly the stranded-notice case boot reconciliation exists to close. Contention is bounded by the shared CAS helper's retry budget and its failure holds the observer cursor (delayed, never lost). 100k is the registry's overflow bound, not an expected population; per-owner marker rows are the follow-up if measured contention ever demands it.

(Reviewed at c046f2b.)

[henrypark133]

High — PushOwned notices have no recovery path after a claimed delivery fails (confidence 98)

The coordinator scans PendingArbitration and Granted notices but not PushOwned notices. After claim_push transitions a notice to PushOwned, a crash or failed delivery leaves it in that state permanently; restart and subsequent ticks neither retry the push nor fall back to another surface.

Fix: Include PushOwned notices in recovery and settle or retry them using the same stable delivery identity, with explicit handling for failed, unavailable, and interrupted delivery attempts.

[BenKurrek]

Deliberately not re-driven, and the module header now says so instead of claiming push-owned records are reconciled. Push ownership is claimed by CAS before the single egress attempt; after a crash nothing can prove that attempt never left the process, so a re-drive risks a duplicate OS notification on every crash loop. The notice stays unread in-app (badge + next-open replay), which is the §6.1 no-presenter row, and a synchronous failure is already recorded by the outbound attempt with its failure kind. run_completion_push_claims_ownership_and_delivers_the_typed_part_to_the_capable_target (run_delivery_contract.rs) now also pins that re-driving an owned notice with the same delivery identity does not egress twice.

(Reviewed at c046f2b.)

[henrypark133]

High — New production descriptor construction uses expect (confidence 90)

The diff adds two production .expect() calls while the repository rule forbids unwrap/expect in production code. A malformed or future-invalid static policy now turns route construction into a process panic instead of a propagated error.

Fix: Use the crate’s non-panicking construction/error path, or prove the descriptor at compile time without a runtime expect.

[BenKurrek]

Left as is. Both sites follow this file's established shape for static route policy — the pre-existing descriptor helpers (mutation_policy, read_policy, descriptor, the body/rate-limit constructors) use the same .expect(...) with a // safety: rationale — and the panic baseline (scripts/check_no_panics.py --reborn-baseline) accepts them. The descriptor contract test pins the exact policy shape, so a future-invalid static policy fails that test before it can reach startup. Making webui_v2_routes() fallible for constant inputs would ripple through every route consumer for no reachable failure.

(Reviewed at c046f2b.)

[henrypark133]

Medium — Durable socket ticket minting is unbounded (confidence 100)

The durable adapter never enforces MAX_OUTSTANDING_SESSION_SOCKET_TICKETS. Unconsumed tickets leave persistent secret and lease records, while consumed leases are retained. An authenticated caller can mint tickets at the route limit without upgrading and grow shared durable storage indefinitely.

Fix: Enforce an atomic durable outstanding-ticket bound with expiry and terminal-record cleanup, and clean up the secret when lease creation fails.

[BenKurrek]

Partially. A secret whose one-shot lease cannot be created is now deleted at mint time instead of waiting for expiry. The outstanding-count bound is deliberately not re-implemented in the durable adapter: mint is rate-limited per caller (12/min), every ticket row carries a 15 s expires_at that consume rejects, and the lease id is the only handle the browser ever holds — so the growth is bounded per caller and never authenticates. Sweeping expired secret/lease rows is the secret store's own contract (the same one-shot lease protocol backs the OAuth PKCE verifiers), so that sweep belongs there as a follow-up rather than in this adapter.

Review round 3 — triage of the multi-agent review (31 findings), the approach audit, and the remaining CodeRabbit/IronLoop threads. Inline threads carry their own replies; this covers the body-only findings and the audit.

Fixed (body-only findings)

• bugs-5 — run-completions/client.ts now re-registers the stream after a non-retryable subscription error: rebase from the durable snapshot, then subscribe from its head, bounded to three consecutive terminal failures so a selector the server keeps rejecting degrades to snapshot-only instead of looping. The same change fixed an unrelated latent bug: subscribeStream never used the snapshot's resume_sequence, so every boot replayed the owner's history from origin.
• resource-3 / resource-4 — coordination.ts: the storage-less claim fallback is a TTL-pruned map released with the notice, and liveStates deletes expired peer entries instead of only filtering them.
• resource-2 — coordinator shutdown aborts and awaits the worker when the budget elapses instead of detaching it.
• performance-2 — local_os validation is memoized per browser profile for one owner pass (one probe per browser, not one per intent).
• mechanical-2 / mechanical-3 — digest prefixes go through str::get, never a byte-index slice.
• mechanical-5 — store.rs 1,638 → 1,320 lines by moving its lifecycle tests to store/tests.rs; the composition observer/probe tests live in sibling files for the same reason (and so the composition mass gate counts production lines only).
• mechanical-4 — ran the default-features clippy lane and the prod-shape (--lib) lane for composition/assistant/webui alongside --all-features.

Fixed (approach audit)

• SP3 — composition no longer interprets the registration document. ironclaw_web_app::RegistrationDocument is the one owner of the grammar (keys, user agent, optional bounded browser_instance_id); the web-app delivery adapter and the composition enrollment probe both parse through it, and an unparseable document counts as neither correlated nor legacy presence (it can never be pushed to).
• SD3 (error mappings) — one translation (operations::surface_error) now serves both the HTTP operations and the RunCompletions stream selector.
• SD3 (comparator) — one compareSequences in run-completions/sequence.ts, imported by the eager store and the lazy protocol module.
• SD7 — SessionSelector is the closed thread | run_completions union, mirroring ProductStreamSelector.
• EI3 — the implementation plan carries a dated status banner (executed by this PR; deviations and deferrals named) rather than retro-ticked boxes.
• EI1 — the design doc now carries an implementation note under §5.1 recording that same-browser live-stream arbitration shipped page-owned (BroadcastChannel + profile-local ledger) while the service worker owns push dedupe, display, click routing and tag clearing, with the §5.5 credential reason. Whether to move the arbiter into the worker is an open follow-up decision, not silently dropped — this one needs a maintainer call.

Left as designed, with reasons

• SD3 (RunCompletionOwner vs NotificationRecipient) — the assistant crate already carries several (tenant, user) shapes for different owners (OutboundDeliveryTargetScope, DeliveryDefaultScope, DeliveryRegistrationScope); the inbox's recipient is not a canonical identity type, and aliasing the notice owner to it would couple the notice store's private helpers to the inbox crate for a field-for-field twin that evolves with a different contract.
• performance-3 (serial owner ticks) — the worker is wake-driven and each tick normally covers a handful of owners; bounded-parallel owner scheduling is a scale change with no measured driver yet.
• dos-3 (inbound frame budget) — per-connection frames are bounded at 8 KiB at both the transport and the parser, connections at 3 per caller, lifetime at 5 min, and a ping costs one parse and one pong; a token budget would bound work that is already bounded.
• matrix-1 (libSQL/Postgres reopen test) — the store never branches on a backend; it is a typed wrapper over the filesystem plane's records + ensure_index + CAS, whose dual-backend parity is the filesystem crate's conformance suite. A per-store reopen matrix would test that suite again.
• mechanical-6 (api.ts at 1,002 lines) — the addition is five thin route helpers; the repository's file-size norm applies to Rust modules and there is no frontend split convention to follow yet.
• mechanical-7 (design doc length) — documentation; noted, not split.

CodeRabbit / IronLoop leftovers

• DeliveryTargetCapabilities: the default test now asserts run_completions == false and a legacy-JSON decode test pins the fail-closed default.
• tests/AGENTS.md bin counts corrected (64 flat bins including the new one) and the new scenario row added.
• WebUI CONTRACT.md streaming section rewritten for the session socket + compatibility SSE (no more stream_events_ws, correct regression test names).
• parse_run_completion_cursor logs the rejected cursor's cause before the sanitized 400.
• Newtypes for notice_id / opaque_thread_tag remain deferred as previously stated (three-crate change; grammar enforced at the producing and consuming seams).

Verification on this tree: cargo fmt; clippy --all-targets --all-features, --all-targets (default), and --lib (prod shape) over the six touched crates plus the integration crate, all -D warnings; cargo test -p ironclaw_architecture_tests; targeted suites for assistant (run_completions, run_delivery, run_delivery_contract), composition (run_completion*), web_app, web_app_extension, outbound, webui (webui_v2_handlers_contract, webui_v2_descriptors_contract), and the root bins reborn_integration_run_completion_notifications + reborn_integration_session_events; frontend pnpm test (1,509), pnpm lint, pnpm build (bundle budget: /chat 225.0 KB gzip, 1.0 KB headroom); bash scripts/ci/check-composition-budget.sh; python3 scripts/ci/docs_publication_boundary.py.

Read the replay cursor before the unread snapshot.

A notice can be created after unread_snapshot returns but before head_sequence reads. The response then omits that notice and returns its sequence as resume_sequence. RunCompletionStreamHub::subscribe replays strictly after that value, so the client receives neither a snapshot item nor replay until a later rebase.

Read the head first, then build the snapshot, or expose both from one consistent store operation. Add a regression test that creates a notice between the two reads.

Use LookupErrorPolicy::Fail, not SkipEntry, for the single completion-capable channel lookup.

resolve_effective_notification_channels_arc is called here with LookupErrorPolicy::SkipEntry. Per that policy's own contract, a per-entry backend lookup failure lands in NotificationChannelResolution::skipped and the resolution continues — it never becomes an Err. resolve_completion_target only reads resolution.channels, so a transient failure on the one entry that could carry run_completions: true makes the loop find nothing and return Ok(None).

attempt_push treats Ok(None) as "no completion target configured" (return Ok(false)), and the coordinator's fallback then settles the notice as NoExternalTarget permanently. This defeats the comment right next to that call: "Unknown selection state: fail retryably rather than settling NoExternalTarget on a backend outage." A transient error on the sole completion channel is now indistinguishable from "the user has no completion channel," and the notice never retries.

Use LookupErrorPolicy::Fail here (this function expects at most one match, unlike the broader fan-out case SkipEntry protects), or check resolution.skipped and propagate an OutboundError when it is non-empty before falling through to Ok(None).

Invalidate stale snapshot writes.

rebase() writes its fetched snapshot after stopRunCompletions() has reset the owner-scoped cache. If account A signs out while this request is pending, its response can repopulate the global cache after account B signs in. Account B can then see A’s completion metadata until a newer rebase wins.

Capture a lifecycle epoch before the await. Reject the result unless that epoch still matches before rebaseFromSnapshot(). Also prevent a stale caller from subscribing with the old cursor. This violates the per-signed-in-owner cache invariant stated at Lines 107-110.

334-338: 🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win

Capture the stream head before the unread snapshot.

A notice created after unread_snapshot but before head_sequence is absent from notices while resume_sequence includes its sequence. The next subscription replays only records after that cursor, and no live receiver existed during this HTTP request. The unread notice can remain unseen until a later rebase.

Read the head before the snapshot, or add an atomic store operation that returns both values. Add a caller-level regression test that inserts a notice between these reads and verifies that the notice reaches the client.

As per coding guidelines: “New or changed production-wired behavior needs a caller-level test at the nearest meaningful seam.”

Do not truncate thread_id; it is an identifier, not display copy.

truncate_chars cuts at the cap and appends …, so an over-long id becomes a different id instead of being rejected. Two concrete consequences:

• Line 137 percent-encodes the full thread_id for the deep link, while this field may carry the truncated form. The url and thread_id in the same payload then disagree, and the worker cannot map the notification back to the thread it opens.
• notice_id (Line 146) feeds the worker dedupe ledger. A truncated id collides with or misses the real notice.

192 chars is above any real id today, so this is a latent corruption path rather than a live bug. Reject the over-long id instead of silently rewriting it — the same fail-loud rule that governs the rest of this payload builder.

Assert which selector survived, not how many.

Both subscriptions in this test use the default sub prefix, because neither subscribe call passes idPrefix. Mapping subscription_id.split("-")[0] therefore yields ["sub"] whenever exactly one subscription remains. The assertion passes even if the wrong subscription survived and the run_completions one was dropped. Assert the selector, which is the invariant the non-retryable drop path must hold.

💚 Proposed test change

-  assert.deepEqual(
-    streams[1].subscriptions.map((entry) => entry.subscription_id.split("-")[0]),
-    ["sub"],
-    "only the surviving selector is named on the next connection",
-  );
+  assert.deepEqual(
+    streams[1].subscriptions.map((entry) => entry.selector),
+    [{ kind: "run_completions" }],
+    "only the surviving selector is named on the next connection",
+  );

Note: ScriptedStream.subscriptions is typed without selector; widen that type to include it.

RFC 9111 no-cache no-store response to POST cacheable text/event-stream browser cache

💡 Result:

Under RFC 9111, HTTP caches are required to "write through" requests with unsafe methods like POST, meaning they must forward the request to the origin server and cannot serve a stored response to such a request [1][2]. While POST responses are generally not cached by standard compliant caches [2], real-world browser and intermediary behavior can be inconsistent, sometimes leading to unexpected caching or buffering of text/event-stream responses [3][4]. To ensure that text/event-stream responses to POST requests are not cached or buffered, you should use the following headers on the response [5][6][4]: 1. Cache-Control: no-store (The most robust directive to prevent any caching of the response) [7][3][8]. 2. Cache-Control: no-cache (Often used in conjunction with no-store, though no-store alone is sufficient to prevent storage) [7][5]. 3. X-Accel-Buffering: no (Crucial if using Nginx as a reverse proxy, as it prevents the proxy from buffering the stream until completion) [6][4]. The no-store directive explicitly instructs all caches (private or shared) not to store any part of the request or the response [1][8]. Because EventSource is natively designed for long-lived GET requests, using POST for streaming often requires using the Fetch API (or libraries like @microsoft/fetch-event-source) to handle the stream manually, as the standard EventSource interface does not support POST [9][10][11]. When using Fetch, ensure these cache headers are set to prevent the browser or intermediate proxies from treating the streamed response as a cacheable resource [6][11][4].

Security Misconfiguration (CWE-525): Use of Web Browser Cache Containing Sensitive Information

Reachability: External · Exploitability: Difficult

Use no-store for caller-scoped event streams as defense in depth.

no-cache permits storage but requires revalidation, and compliant caches do not reuse stored responses for POST. no-store still protects against browser or intermediary implementations that mishandle long-lived text/event-stream responses. Add a route-level header assertion if this cache-isolation policy is required.

Split the session-event tests into their own contract file.

This file now exceeds 10,000 lines, and this PR adds roughly 450 lines to it. The repo rule sets 1,500 lines as the refactor threshold, 3,000 lines as the tracking-issue threshold, and requires an inline justification for a PR that adds more than 200 lines. The new session-event block is self-contained: it has its own helpers (session_events_request, thread_subscription, session_frames) and shares only StubServices, router_with, caller, parse_sse_events, and collect_sse_until. Move it to crates/product/ironclaw_webui/tests/webui_v2_session_events_contract.rs with a shared tests/support module, or name the tracking issue that owns the decomposition.

Repo rule relied on: "A .rs file > 1,500 lines is a refactor the codebase has been postponing. Existing files > 3,000: file a tracking issue for decomposition. PRs that add > 200 lines need an inline justification." As per coding guidelines.

Reuse _next_sse_event instead of a second SSE parser.

_next_sse_event at line 28 already parses SSE blocks in this file, with a timeout and with the event: name and id: captured. _read_session_frame re-implements a subset of that logic. Call the existing helper and read ["data"]. That removes the duplication, gives the test access to the event: name, and reduces the statement count that Ruff flags as PLR0915 on the renamed test. Add the -> dict return annotation to satisfy ANN202.
