fix(harness): recover Agent Map identity without legacy fallback - #893
Conversation
Refs SAP-3089. Keep catalog failures on the selected map, preserve exact session navigation, reject stale retries and obsolete graph events, and record packaged and recovery evidence for the deletion gate.
📝 WalkthroughWalkthroughThe web client now handles unresolved Studio project identities without falling back to the legacy graph. It preserves project and conversation selection, provides identity reload recovery, ignores obsolete graph events, and adds browser and desktop validation for retired graph routes. ChangesAgent Map identity recovery
Priority: ➖ Normal Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to Project identity recovery now preserves and restores map selections without legacy fallback. If selection persistence fails during recovery, the browser can report an unhandled error even though the local selection remains usable. Sequence Diagram(s)sequenceDiagram

Primary change type
Problem and motivation
A current project without catalog identity could enter the older project graph or move its active conversation. Catalog recovery could also restore another project over an explicit selection, and keyboard shortcuts could address a different session list from the visible tabs.
Summary and scope
Keep current projects on durable map authority with a bounded catalog-retry view. Preserve exact selected identities and conversations, reject out-of-order catalog responses, align keyboard and visible session tabs, and keep explicit ordinary Canvas/Steps navigation available. Ignore obsolete graph events before cache invalidation or refresh work.
The packaged smoke test measures legacy calls before cache hits and verifies protected 410 responses. The authority matrix records retained owners, Linux evidence and the local roll-forward recovery rehearsal. Older-server payloads that omit
studioProjectsretain browser compatibility until SAP-3090; backend deletion remains SAP-3091.Release dependency: #892 and #893 must ship together. This layer includes the required browser recovery and removes #892's
.release-blockedfile, allowing the checked versioning and release entrypoints to proceed. The breaking minor HTTP retirement changeset is retained in #892; this PR's patch changeset explains that the browser correction restores the documented read-only selection contract.Screenshots: identity unavailable, recovered saved map.

Validation
Current head:
e4003c9c, including parent5870d0f5and mainb460c9aa.The parent CI repair fixes four definition-list test startup failures also present on main by supplying
credentialsFilePathin the auth mock and isolating its observer path inside the fixture. All 32 related server tests passed locally after the fix. The merged stack also passed Harness build/typecheck and 19 authority/session-tab browser tests, including the newer MCP restart flow.The release check passed all 178 script tests and nine desktop release-tag tests. The actual server-only version/release commands fail with the pending-client explanation, while
pnpm release:checksucceeds with this client layer included. The full Changesets release-plan API resolves the combined queue to Harness 0.17.0 (minor). No versions or published changelogs were changed.The original recovery rehearsal exercised revert → new changeset → real
pnpm version-packages→ local version commit → matching higher desktop tag in a separate clone. No release was published. The authority document distinguishes those earlier rehearsal versions from recovery versions for the eventual breaking minor. Signed macOS upgrade/update-delivery evidence remains SAP-3086.Tests and documentation
Eight authority tests cover missing identity, cross-project recovery, late responses, catalog loss, exact keyboard tabs/Canvas, event rejection and zero legacy/session actions. Existing navigation, initialization, release and full browser suites were exercised. The authority gate records the matrix, concrete evidence, stop conditions, retained owners and recovery limits.
Compatibility and release impact
.changeset/calm-map-identity-recovery.mdremains a patch and now explains in its published text that this restores Studio's documented read-only project-selection contract during catalog failures. The inherited.changeset/quiet-project-map-authority.mdin fix(harness): fence off retired project graph routes #892 marks the documented HTTP contract removal as a breaking Harness minor, names all three routes and410 legacy_graph_retired, and gives the durable Agent Map replacements. Together with the existing patch queue, Changesets selects Harness 0.17.0. The.release-blockeddeletion in this PR clears the server layer's executable release check because the matching client recovery is now present.Security
