* 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 Core documentation
Documentation is organised into four quadrants: tutorials help you learn by doing, how-to guides solve specific tasks, reference states authoritative facts, and explanation explores concepts and design decisions.

Tutorials
- Your first project — install to first shipped phase, one guaranteed path
- Onboarding an existing codebase — bring GSD Core to a brownfield repo
- Build your first capability — author a tiny declarative capability and watch it act in the loop
- Install your first capability — install a third-party capability end-to-end: consent, verify, check for updates, remove
How-to guides
- Install on your runtime — runtime-specific install steps for all 16 supported runtimes
- Install a minimal GSD and add skills later — install only the core skills, then grow the surface with profiles and
/gsd:surface - Attach a plugin-provided skill to a GSD agent — use the
global:plugin:skillentry form to load Claude Code plugin skills into agent prompts - Discuss a phase — capture implementation decisions before planning begins
- Resolve edge-coverage findings — turn the spec phase's surfaced domain-boundary edges into covered, dismissed, or backstopped spec decisions
- Resolve prohibition findings — turn the spec phase's surfaced must-NOT constraints into resolved, dismissed, or deferred spec decisions
- Plan a phase — run research, decompose work, and verify plan quality
- Execute a phase — run plans in parallel waves with fresh-context subagents
- Verify and ship — walk through completed work, diagnose failures, and create the PR
- Run phases autonomously — use autonomous mode for unattended phase execution
- Handle quick and fast tasks — use
/gsd-quickand/gsd-fastfor ad-hoc work outside the phase loop - Configure model profiles — switch between quality, balanced, and budget model tiers
- Set up cross-AI review — configure a second AI to review code produced by the primary agent
- Work in parallel with workstreams — run independent lines of work simultaneously using workstreams
- Isolate work with workspaces — use workspaces to sandbox experimental or risky changes
- Debug a failed execution — diagnose and recover from broken or incomplete phase execution
- Spike and sketch — use
/gsd-spikeand/gsd-sketchfor exploratory work before committing to a plan - Design a UI phase — use the UI phase loop for frontend and visual work
- Develop a Capability for GSD 1.5+ — add feature Capabilities, hook fragments, and registry entries
- Add or update a host's integration — set a host's documentation-sourced
runtime.hostIntegrationaxes (ADR-1239 Phase A), with theundocumentedsentinel rule - Turn a capability off (and keep it off) — disable a capability via the surface, or gate individual hooks off without removing the capability
- Drive GSD from a tracker issue — start a phase from a GitHub, Linear, or Jira issue
- Migrate from GSD 2 — upgrade an existing GSD 2 project to GSD Core
- Update GSD — re-run the installer to pick up the latest release
- Clean up get-shit-done-cc — remove leftover old-package artifacts that cause a spurious
⬆ /gsd:updateindicator after migrating to@opengsd/gsd-core - Fix the worktree base-mismatch (exit 42) error — resolve the branch-divergence condition that halts parallel phase execution
- Recover and troubleshoot — fix common problems, rebuild context, and uninstall

Explanation
- Context engineering — how context rot forms and how GSD Core prevents it
- The phase loop — design rationale for the Discuss → Plan → Execute → Verify → Ship cycle
- Multi-agent orchestration — how subagents are spawned, scoped, and coordinated
- Security model — trust boundaries, permissions, and safe automation
- The capability trust model — why third-party capabilities are gated by consent + integrity + reversibility, not a sandbox
- How overlay capabilities compose — why first-party always wins and how the loader resolves precedence, conflicts, and fail-open load-failure warnings
- Architecture — system architecture, agent model, and data flow
- The Embeddable Orchestration System — one public, versioned contract for embedding GSD across many hosts
- Discuss modes — assumptions mode vs interview mode for
/gsd-discuss-phase - Context monitoring — context window monitoring hook architecture
- Issue-driven orchestration — recipe for driving GSD from a tracker issue using existing primitives
