Subject: [PATCH 01/25] fix(setup): align tool order with analyze --ai-configs
 sequence
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Common tools (Claude Code → Cline/Roo → Mistral Vibe) now follow the same
order as the analyze --ai-configs prompt. Setup-only tools follow after:
OpenCode, GSD, BMAD, omoa.

Also document why recursive CTE BFS was reverted in bfsFromDB comment.

Subject: [PATCH 02/25] fix(gate): exclude phantom decisions from
 no_decisions_recorded bypass
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Stale phantom decisions from prior sessions were counting as activeDecisions,
silently disabling the pre-commit gate for all future commits. Phantom means
"recorded but no code evidence found in diff" — it should not shield unrelated
future commits. Added 26 tests for decisions handlers (0%→88%) and orient
branch coverage (56%→61% branches).

Subject: [PATCH 03/25] fix(decisions): replaceDecisions fixes consolidation
 silent drop bug
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

upsertDecisions skips existing IDs, so consolidated decisions sharing IDs
with their rejected original drafts were silently no-oped — the gate never
saw verified decisions to present for approval. replaceDecisions always
overwrites, ensuring verified/phantom status overwrites the rejected
placeholder set in the prior step.

Subject: [PATCH 04/25] feat(decisions): sentinel-based --no-verify bypass
 detector
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Pre-commit hook writes .git/SPEC_GEN_GATE_RAN after gate passes.
Post-commit hook (not skipped by --no-verify) checks for it — if absent,
prints a visible warning that the gate was bypassed and decisions were
not reviewed. Normal commits clean up the sentinel silently.

Subject: [PATCH 05/25] feat(decisions): gate blocks on approved-not-synced
 decisions

Approved decisions must be synced to spec files before committing.
Gate now emits `approved_not_synced` reason code and exits 1 when
any decision is in `approved` state.

Subject: [PATCH 06/25] feat(decisions): always write ADR for every synced
 decision
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Remove isArchitectural keyword-threshold gate — any approved decision
is significant enough to warrant an ADR. The keyword filter was too
narrow and missed real architectural decisions (SQLite, gate logic).

Backfill openspec/decisions/ with ADRs for 3 already-synced decisions.

Subject: [PATCH 07/25] test(analysis): cover inventory handlers,
 getMinimalContext, getCluster, detectChanges
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds 36 tests for previously uncovered handlers:
- handleGetMiddlewareInventory/SchemaInventory/UIComponents/EnvVars/ExternalPackages
  (cached hit + live fallback for each)
- handleGetMinimalContext: no graph, function not found, callers/callees, testedBy edges
- handleGetCluster: no graph, no function, no community, members + stats
- handleDetectChanges: no graph, git-not-repo error path
- handleAuditSpecCoverage: error path

Statements: 30% → 61% on analysis.ts. Overall: 80% → 81.3%.

Subject: [PATCH 08/25] fix(decisions): address review findings from PR #78
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Sentinel path: use `git rev-parse --git-dir` instead of hardcoded .git/
- Sentinel comment: clarify it marks a passed gate, not a bypass
- `consolidatedRecently`: extract magic 60-min window to CONSOLIDATION_GRACE_PERIOD_MS constant
- Gate: remove dead `missing.length === 0` guard (missing always empty at that point)
- decisions.test.ts: remove duplicate mockResolvedValue in beforeEach
- decisions.test.ts: add duplicate-title test (makeDecisionId is deterministic → upsert skips)
- syncer.ts: document why every decision gets an ADR (no keyword filter)

- Preserve recordedAt from original draft during consolidation: replaceDecisions
  overwrites the row, losing when the decision was first recorded. Fix: carry forward
  original.recordedAt when consolidated ID matches an existing draft.
- Guard --approve on synced decisions: re-approving a synced decision would mark it
  approved again and force another --sync cycle. Block with error instead.
- Centralize inactive status set: add INACTIVE_STATUSES, isBlockingStatus,
  requiresSync to store.ts. Replace inline ['rejected','synced','phantom'] filter
  in gate with INACTIVE_STATUSES.has() to prevent divergence across handlers.
- Extract CONSOLIDATION_GRACE_PERIOD_MS constant (already in previous commit).

Subject: [PATCH 10/25] fix(decisions): use IDs as traceability anchor in
 consolidation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Pass existing non-draft decisions (with their stable IDs) to the
consolidation LLM. The LLM now reuses an existing ID when it recognises
the same architectural concept, instead of minting a new one from a
potentially varied title. A LLM-supplied ID is only accepted when it
matches a known existing decision ID — fabricated IDs are silently
ignored and a new ID is derived as before.

This prevents the duplicate-decision problem where two consolidation
runs on the same diff produced different IDs due to LLM title phrasing
non-determinism.

-Decisions are consolidated and cross-checked against the git diff before each commit.
+Decisions are consolidated in the background immediately after `record_decision` is called — the pre-commit gate reads the already-consolidated store and adds no LLM latency.
 
 **Performance note**: if you skip `record_decision`, the gate detects unrecorded source changes at commit time and triggers a slow LLM extraction on the *next* commit (~10-30s). Calling `record_decision` proactively keeps every commit instant.
 
 ## When git commit is blocked by the decisions gate

 > 1. **[id]** Title — rationale
-> Do you approve? (yes/no)"
-
+Do you approve? (yes/no)"
 For each approval call `approve_decision`, for rejections call `reject_decision`.
 Then run `spec-gen decisions --sync` and retry `git commit`.
 
+**`reason: "approved_not_synced"` — decisions approved but not written to specs:**

-
 If yes: run `spec-gen decisions --consolidate --gate` and handle the result.
 If no: retry with `git commit --no-verify` to skip the gate.
 
 **`reason: "no_decisions_recorded"` — source files staged but nothing recorded:**

Subject: [PATCH 12/25] feat(decisions): purge inactive decisions from store
 after sync
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After decisions are synced their content lives in ADR files and spec.md
committed to git — the store entries are redundant. purgeInactiveDecisions()
now runs inside syncApprovedDecisions before saving, dropping synced,
rejected, and phantom entries. The store stays bounded by active work only.

The in-memory store returned to callers is left unpurged so the sync result
(synced list, modifiedSpecs) remains fully observable.

Subject: [PATCH 13/25] feat(decisions): extend RAG and orient with decision
 context
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

ADR files (openspec/decisions/adr-*.md) are now indexed in the spec
vector index under domain "decisions". Agents calling search_specs or
orient will find relevant past decisions via semantic search — no need
to read ADR files manually.

orient's pendingDecisions filter now uses INACTIVE_STATUSES for
consistency and restricts results to decisions matching the task's
relevant domains or files (instead of dumping all active decisions).
Approved decisions always surface regardless of domain match — the
agent must sync them before committing.

 **How they relate**: they address different failure modes and do not substitute for each other.
 
 The decisions gate asks: *"has this architectural choice been reviewed by a human?"* It operates on decisions recorded during development — it has no knowledge of which spec files cover which source files.

Subject: [PATCH 15/25] fix(decisions): use earliest superseded recordedAt for
 merged decisions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When consolidation merges multiple drafts into one new decision (new ID,
no direct match in originalById), the provenance map previously fell back
to the consolidation timestamp — erasing when the underlying work was first
captured. Now uses the earliest recordedAt across all superseded draft IDs
so the audit trail anchors to the real start of the work.

Subject: [PATCH 16/25] feat(decisions): add decision scope tiers to gate ADR
 creation

Introduce DecisionScope = 'local' | 'component' | 'cross-domain' | 'system'.
Only cross-domain and system decisions produce ADR files, preventing ADR spam
from trivial implementation choices.

- qualifiesForADR() in syncer gates ADR creation on scope
- Consolidation LLM prompt includes scope classification with explicit negative
  rules; extractor capped to local/component (cross-domain upgrade requires
  full multi-domain context visible only at consolidation time)
- record_decision auto-promotes scope via two deterministic triggers:
  structural (files span 2+ distinct top-level dirs) or semantic
  (multi-domain + contract keyword + not refactor)
- GATE_REASONS constant centralizes all 4 gate reason codes in constants.ts
- synced re-approval guard added to MCP handleApproveDecision handler
- --sync always calls syncApprovedDecisions so purgeInactiveDecisions runs
  even when no approved decisions exist (fixes early-exit purge skip)
- scope badge in decisions --list (gray/blue/yellow/red by tier)
- Backward compat: pending.json without scope treated as component

+27 tests: scope gate, auto-promotion triggers, consolidator scope mapping,
synced re-approval guard, structural/semantic promotion triggers.

Subject: [PATCH 18/25] fix(watcher): replace glob ignored with function to
 prevent EMFILE on macOS

chokidar v5 on macOS (kqueue) opens file descriptors for all directories
before evaluating glob patterns, consuming 20k+ FDs on node_modules alone.

Switch ignored to a function that checks string segments before any FD is
opened. Also add followSymlinks: false to reduce watch surface further.

Subject: [PATCH 19/25] fix(deps): replace better-sqlite3 with node:sqlite
 built-in

Eliminates native addon compilation requirement, enabling installation
in isolated environments (Nexus, restricted networks) where GitHub
prebuilts are unavailable.

- Migrate EdgeStore to node:sqlite DatabaseSync API
- Replace db.transaction() with SAVEPOINT-based runTransaction() helper
  to support nested transactions (node:sqlite has no native nesting)
- Update named params from { name: v } to { '@name': v } format
- Replace db.pragma() with db.exec('PRAGMA ...')
- Remove better-sqlite3 and @types/better-sqlite3 from dependencies
- Bump engines.node to >=22.5.0 (node:sqlite available since 22.5.0)

+**Claude Code — MCP config (token-efficient two-server setup)**
+
+MCP clients load all tool schemas at session start. With 45 tools, this costs ~8–77k tokens before any work begins. Claude Code supports `alwaysLoad: false` (deferred, default) — tools load only when the agent searches for them via Tool Search.
+
+The recommended setup uses two server entries: one always-visible core server and one deferred full server:
+
+```json
+{
+  "mcpServers": {
+    "spec-gen-core": {
+      "type": "stdio",
+      "command": "spec-gen",
+      "args": ["mcp", "--minimal"],

+      "command": "spec-gen",
+      "args": ["mcp"],
+      "alwaysLoad": false
+    }
+  }
+}
+```
+
+- **`spec-gen-core`** exposes 5 tools always visible in context (~500 tokens): `orient`, `search_code`, `record_decision`, `detect_changes`, `check_spec_drift`. These are the tools most likely to be called at session start.
+- **`spec-gen`** exposes all 45 tools deferred — loaded on demand when the agent uses Tool Search (e.g. "find tool for BFS graph traversal").
+
+If you only need one server entry, use `alwaysLoad: false` (the default) with the standard `spec-gen mcp` command — all tools are deferred and searchable via Tool Search.

 tool discovery
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Derives a ranked list of relevant spec-gen tools from what orient already
knows (hub presence, spec domains, task keywords) — no extra I/O.

Works on any MCP client without Tool Search: agent reads orient output,
sees suggestedTools, knows which tools to request next. Complements the
Claude Code --minimal + Tool Search setup for Cline/Cursor/OpenCode users.
