[Hillary Mutisya (hillary-mutisya)]

Summary

• Add bounded, corpus-qualified document/event entity, topic and maintained-hierarchy graphs. Eligibility, suppression, event authority, exact provenance/counts, generation-bound node/edge/support paging, budgets and explicit building/stale/error/unsupported coverage remain visible.
• Separate index preparation from reads; invalidate graph caches across document/event lifecycle changes. Reuse merged curated topics/lazy summaries, preserve current source fingerprints and historical conflict fallback, and revalidate detached view/event preparation before installing results.
• Expose graph operations through service, in-process/MCP clients, RPC/browser gateway and strict protocols. Advertise graph support truthfully, including host-specific MCP tool inventories.
• Add scoped Explore/overview, graph controls/visualizers/details and safe evidence drilldown. Finish generic Views card/list-detail/build flyout, grouped activity/Inbox/navigation and lazy summary inventories with responsive detail readers.

Independent base and exclusions

Targets main, not PR3. Prerequisites #3224 (Questions/acquisition) and #3225 (quality/curated lazy topics) are merged. Extracted from the immutable integration source using two-tip comparisons while retaining main's later fixes. No PR3 coordinator, automatic corpus question discovery, knowledge checkpoint/policy/readiness API/UI, integrated source-plus-view answering, or benchmark harness integration is included. Existing Questions functionality is retained.

Validation

All final local checks passed in the isolated PR4 worktree:

• pnpm run build from ts (full workspace).
• Complete memory-service offline unit suite: 80 suites, 1,030 tests. From ts/packages/memory/service: pnpm run jest-esm --maxWorkers=2 --workerIdleMemoryLimit=512MB --testPathPattern=".*[.]spec[.]js$" (local NODE_OPTIONS=--max-old-space-size=8192). Includes graphService/Projection/Paging, viewIndexConcurrency, snapshot reuse/freshness/historical conflict parity, topic/event/privacy lifecycle, all view/editorial/consolidation and other existing service regressions.
• pnpm --filter @typeagent/memory-client run test:local: 48 tests.
• pnpm --filter @typeagent/memory-mcp-server test: 12 suites, 39 tests (real bounded MCP protocol round trips and host inventory included).
• pnpm --filter @typeagent/browser run test:views:gateway: 111 tests, including scoped graph gateway and strict validation/lifecycle.
• pnpm --filter @typeagent/browser run test:views:client: 41 suites, 371 tests, including graph/Explore/Views/activity/Questions/management.
• Pinned pnpm run prettier:changed.
• pnpm run code-lint -- --ratchet --base origin/main.
• pnpm run code-complexity:ci.
• pnpm run code-circular -- --ratchet --base origin/main --exceptions-file tools/scripts/code/circular-baseline-exception.json (not concurrent with Git-fixture tests).
• pnpm run code-debt -- --gate --base origin/main.

Coverage is deterministic/offline; no live inference, qualification pilot, recording or long-lived server was used. These checks do not establish generated knowledge/answer quality. Read-only graph responses may report separately scheduled preparation or unsupported provider projections rather than claim completeness.

CI remediation

The first matrix run exposed two pre-projection hydration-count expectations in snapshotReuse. The follow-up ordinary commit asserts one fresh projection read and zero full-state hydrations, while retaining expired-scope freshness, privacy checks and historical consolidation parity. The complete 80-suite service run passes after this fix; no test or gate was disabled.
