Discarded commits leave a forensic log of commit keys and roles, never content. Conversation rows gain a commit_key (migration 071): keyed saves are idempotent under retry, validated against the full commit identity, and refused when they would cross a workstream deletion. The prune orphan category now requires a NULL alias plus a two-hour updated grace, with cutoffs computed at discovery time and carried into both dialects' rechecks. The mid-turn interjection queue is owner-partitioned with no per-site mode flags: pops take the acting principal's and unowned rows, other participants' rows are structurally retained, and enforcement lives at queue admission plus the shared before_spawn gates. The retraction ledger is bounded by open pop windows: pops open a window atomically with the queue delete, restores close their ids atomically with the ledger consume, every other exit closes through one helper, and misses for unheld ids record nothing. The workstream-gone latch refuses unattended wakes at all three gates (watcher spawn, claim, delivery pre-pop), and the retry dispatcher regained its pre-envelope cancel/error convergence net. Persistence-state reporting derives through the session bound to each UI instead of a registry lookup by id that failed open to healthy during tombstone retention. The dashboard roster no longer re-inserts ghost entries from trailing activity events, the history tool-outcome scan tolerates interleaved non-turn rows, and the shared handoff-deadline handle owns its own retirement. Single-sourced across call sites: keyed-commit row values, attachment save wrappers, tail-truncation and conflict-resolution bodies for both storage dialects; worker-slot lifecycle field sets; the direct-commit admission frame; queued-row layout accessors; the string-aware comment stripper shared by every JS harness suite. Refs #981 #964 * fix(session): sweep handoff fixes to their sibling surfaces The interactive replay loop treated a system row as a tool-batch boundary, so every tool result after an interleaved row vanished from that pane while the coordinator rendered the same history correctly. Only a conversational turn ends the batch window now, matching the shared outcome index. Accepted user turns clear the composer's attachment chips on the same viewer policy that settles optimistic bubbles rather than on having matched a local bubble, so a workstream created with an upload no longer keeps a chip for an attachment the create dispatch already consumed. The coordinator's raced-Stop arm emits the stream-end hook it inherits alongside the idle state, leaving no unfinalized bubble or unflushed tool output. Ending a session surfaces a failure toast when the request never lands or answers with a non-JSON body. The per-second persistence reconcile now probes each session without blocking: a workstream whose generation and handoff locks are held is skipped until the next pass instead of contending the locks every commit needs. The one-shot repair that gates workstream creation at capacity keeps a definite probe — it has no next pass, and the sessions likeliest to be contended are the ones whose unresolved journals emptied its candidate list. Single-sourced: the attachment lane builds its conversation row through the shared commit-identity builder; the ordinary worker exit releases its slot through the lifecycle owner; both operator surfaces snapshot their counters through one non-consuming helper; the replay preamble loses its per-kind wrappers and its config hook; the browser harness suites share one brace walker; and each in-flight history attempt is one record carrying both its abort controller and its deadline.

Patrick Buckley	7a06f5e8bc	refactor(session): make ModelLane the provider boundary (#979) (#989) ... * refactor(session): make ModelLane the provider boundary (#979) ## Summary This closes the model-lane ownership gap left by #832: `ChatSession` no longer stores raw provider/client handles. `ResolvedModelBinding` now carries the provider, client, model, capabilities, registry generation, and backend-auth configuration as one coherent snapshot. - Atomically rebind existing sessions after model-registry changes while pinning each in-flight send, fallback, judge, output guard, task agent, title, compaction, perception, and voice operation to its initiating principal and binding. - Fence UI publication, canonical trajectory folds, durable writes, streams, retries, child scopes, and judge work by generation. Stop can hand off to a successor without accepting late state; cancelled tools retain typed effect receipts, and concurrent approval batches resolve by exact cycle or call. - Make create, fork, open, close, and delete race-safe with hidden `creating` reservations, incarnation-aware state tails, and an ACL-rechecked transaction that clones checkpoint-bounded history, configuration, project/persona state, and attachment references. - Extend REST/OpenAPI and Python/TypeScript SDK contracts for create/fork inputs, routed-create metadata, live-workstream probes, targeted approvals, and structured cancellation results. - Update architecture, storage, authentication, judge, channel, console, API, and SDK documentation, including regenerated architecture diagrams and OpenAPI artifacts. ## Validation - SQLite suite: 11,188 passed, 9 skipped, 10 deselected - PostgreSQL suite: 11,195 passed, 2 skipped, 10 deselected - Live backend: 3 passed - SSE recovery: 6 passed; browser recovery harness passed all scenarios - Ruff: clean; 595 files correctly formatted - mypy: 243 source files clean - TypeScript: typecheck/build and 35 tests passed - OpenAPI artifacts fresh; all 14 changed diagrams reproduce byte-for-byte - `git diff --check` and Git LFS integrity clean Closes #979. * fix(deps): update nanoid for GHSA-2v37-7h3g-55p8 Refresh the transitive lock entry admitted by PostCSS so the TypeScript security gate no longer resolves the vulnerable custom-generator implementation. Validation: - npm ci - npm audit --audit-level=moderate: 0 vulnerabilities - TypeScript typecheck and build - TypeScript tests: 35 passed * fix(test): assert canonical model registry URLs Replace prefix checks with exact canonical base URL assertions so the tests do not model incomplete URL validation. Validation: tests/test_model_registry.py (185 passed); Ruff check/format; mypy.	2026-08-08 16:13:35 -07:00
