* test(#1964): add failing-first semantic-recall contract tests Epic #1957 Phase 3C (final). Source-text-is-the-product contract tests: semantic recall via MemPalace (top-k meaning-similar prior resolutions, catches same-root-cause/different-wording cases), indexing resolved sessions at archive, graceful degradation to keyword matching when MemPalace is absent, knowledge-base.md stays the durable plain-text source of truth, agent Phase 0 / Matching Logic is semantic-first (the stale 'keyword overlap, not semantic similarity' claim must go), and no new embedding/vector infra (reuse MemPalace). Failing-first: reference, the Matching Logic reframe, the Phase 0 consolidation, and the archive indexing step do not yet exist. * feat(#1964): semantic knowledge-base recall via MemPalace (keyword fallback) Epic #1957 Phase 3C (FINAL). Replaces keyword-overlap matching with semantic recall: at Phase 0 the debugger queries MemPalace with the current symptoms and surfaces the top-k meaning-similar prior resolutions, catching the same-root-cause/different-wording cases keyword overlap missed (the self-noted 'keyword overlap, not semantic similarity' limitation). Resolved sessions are indexed into MemPalace at archive (symptoms + root_cause(s) + fix + recurrence guard). knowledge-base.md remains the durable plain-text source of truth; when MemPalace is absent the debugger falls back to keyword-overlap matching (logged, never a silent skip). No new embedding/vector infrastructure — MemPalace is reused. Size-neutral agent edits: the Matching Logic section reframed (keyword-only -> semantic-first + keyword-fallback + @-include); Phase 0's three keyword bullets consolidated into one semantic-first bullet; one MemPalace-indexing step added at archive. Agent at 57222 B (122 B headroom — final phase). Full rules in gsd-core/references/debugger-semantic-recall.md. INVENTORY + manifest + agent-size baseline + install-parity goldens + AGENTS.md updated. * fix(#1964): address orthogonal review (invocation mechanism, index Resolution-not-symptoms + redaction, fallback detail) - HIGH: the 'query MemPalace' instruction was WHAT-level only; the agent has no MCP tools. Added an Invocation section naming the Bash CLI (mempalace search --wing <wing>) + MCP-when-registered + wing resolution (config.mempalace.wing -> project_code -> project dir), matching every other MemPalace integration. Without this the feature silently degraded to keyword matching even when MemPalace was present. - MEDIUM (security x2): index the agent-authored Resolution summary (root_cause + fix + recurrence_guard), NOT raw user-supplied Symptoms — excludes attacker-controlled prose from the cross-session index AND reduces secret/PII leakage. Redact secret-shaped values before indexing. Stated the write order (KB append + commit MUST succeed before indexing). - LOW: restored 'identifiers' + 'case-insensitive' to the keyword fallback; added a test asserting the fallback mechanics survived the Phase 0 consolidation (Error patterns field, 2+ token overlap, identifiers, case-insensitive). * chore(#1964): ratchet agent-size baseline downward (leaner archive bullet shrank gsd-debugger.md 57222->57197) * chore(#1964): backfill changeset pr number (PR #2416)

**`gsd-debugger` now recalls prior resolved sessions semantically via MemPalace instead of keyword overlap** — at Phase 0 the debugger queries MemPalace with the current symptoms and surfaces the top-k meaning-similar prior resolutions as candidate hypotheses, catching the same-root-cause / different-wording cases keyword overlap missed (a prior "requests hang under load" now surfaces for "API times out when many users connect"). Resolved sessions are indexed into MemPalace at archive (symptoms + root cause(s) + fix + recurrence guard). `knowledge-base.md` remains the durable plain-text source of truth; when MemPalace is absent the debugger falls back to keyword-overlap matching against it (logged, never a silent skip). No new embedding/vector infrastructure — MemPalace is reused. Full rules live in `gsd-core/references/debugger-semantic-recall.md`. (#1964)
