fix(init): ignore archived phases from prior milestones sharing a phase number (#2186)

When a new milestone reuses a phase number that exists in an archived
milestone (e.g., v2.0 Phase 2 while v1.0-phases/02-old-feature exists),
findPhaseInternal falls through to the archive and returns the old
phase. init plan-phase and init execute-phase then emitted archived
values for phase_dir, phase_slug, has_context, has_research, and
*_path fields, while phase_req_ids came from the current ROADMAP —
producing a silent inconsistency that pointed downstream agents at a
shipped phase from a previous milestone.

cmdInitPhaseOp already guarded against this (see lines 617-642);
apply the same guard in cmdInitPlanPhase, cmdInitExecutePhase, and
cmdInitVerifyWork: if findPhaseInternal returns an archived match
and the current ROADMAP.md has the phase, discard the archived
phaseInfo so the ROADMAP fallback path produces clean values.

Adds three regression tests covering plan-phase, execute-phase, and
verify-work under the shared-number scenario.

 ## [Unreleased]
 
+### Added
+
+- **`@gsd-build/sdk` — Phase 1 typed query foundation** — Registry-based `gsd-sdk query` command, classified errors (`GSDQueryError`), and unit-tested handlers under `sdk/src/query/` (state, roadmap, phase lifecycle, init, config, validation, and related domains). Implements incremental SDK-first migration scope approved in #2083; builds on validated work from #2007 / `feat/sdk-foundation` without migrating workflows or removing `gsd-tools.cjs` in this phase.
+- **Flow diagram directive for phase researcher** — `gsd-phase-researcher` now enforces data-flow architecture diagrams instead of file-listing diagrams. Language-agnostic directive added to agent prompt and research template. (#2139)
+
+### Fixed
+
+- **SDK query layer (PR review hardening)** — `commit-to-subrepo` uses realpath-aware path containment and sanitized commit messages; `state.planned-phase` uses the STATE.md lockfile; `verifyKeyLinks` mitigates ReDoS on frontmatter patterns; frontmatter handlers resolve paths under the real project root; phase directory names reject `..` and separators; `gsd-sdk` restores strict CLI parsing by stripping `--pick` before `parseArgs`; `QueryRegistry.commands()` for enumeration; `todoComplete` uses static error imports.
+
+### Changed
+
+- **SDK query follow-up (tests, docs, registry)** — Expanded `QUERY_MUTATION_COMMANDS` for event emission; stale lock cleanup uses PID liveness (`process.kill(pid, 0)`) when a lock file exists; `searchJsonEntries` is depth-bounded (`MAX_JSON_SEARCH_DEPTH`); removed unnecessary `readdirSync`/`Dirent` casts across query handlers; added `sdk/src/query/QUERY-HANDLERS.md` (error vs `{ data.error }`, mutations, locks, intel limits); unit tests for intel, profile, uat, skills, summary, websearch, workstream, registry vs `QUERY_MUTATION_COMMANDS`, and frontmatter extract/splice round-trip.

+
+## Step 3: Handle Agent Return
+
+Inspect the return output for the structured return header.
+
+### 3a. ROOT CAUSE FOUND
+
+When agent returns `## ROOT CAUSE FOUND`:
+
+Extract `specialist_hint` from the return output.
+
+**Specialist dispatch** (when `specialist_dispatch_enabled` is true and `tdd_mode` is false):
+

+
+How would you like to proceed?
+1. Fix now — apply fix immediately
+2. Plan fix — use /gsd-plan-phase --gaps
+3. Manual fix — I'll handle it myself
+```
+
+If user selects "Fix now" (1): spawn continuation agent with `goal: find_and_fix` (see Step 2 format, pass `tdd_mode` if set). Loop back to Step 3.
+
+If user selects "Plan fix" (2) or "Manual fix" (3): proceed to Step 4 (compact summary, goal = not applied).

+Spawn continuation agent with `tdd_mode: true`. Loop back to Step 3.
+
+### 3b. TDD CHECKPOINT
+
+When agent returns `## TDD CHECKPOINT`:

+Display test file, test name, and failure output to user via AskUserQuestion:
+```
+TDD gate: failing test written.

+Test file: {test_file}
+Test name: {test_name}
+Status: RED (failing — confirms bug is reproducible)
+
+Failure output:
+{first 10 lines}
+
+Confirm the test is red (failing before fix)?
+Reply "confirmed" to proceed with fix, or describe any issues.
+```
+
+On confirmation: spawn continuation agent with `tdd_phase: green`. Loop back to Step 3.
+
+### 3c. DEBUG COMPLETE
+
+When agent returns `## DEBUG COMPLETE`: proceed to Step 4.
+
+### 3d. CHECKPOINT REACHED

+Loop back to Step 3.
+
+### 3e. INVESTIGATION INCONCLUSIVE
+
+When agent returns `## INVESTIGATION INCONCLUSIVE`:
+
+Present options via AskUserQuestion:
+```
+Investigation inconclusive.
+
+{what was checked}
+
+{remaining possibilities}

+Options:
+1. Continue investigating — spawn new agent with additional context
+2. Add more context — provide additional information and retry
+3. Stop — save session for manual investigation

+## Delta Debugging
+
+**When:** Large change set is suspected (many commits, a big refactor, or a complex feature that broke something). Also when "comment out everything" is too slow.
+
+**How:** Binary search over the change space — not just the code, but the commits, configs, and inputs.
+
+**Over commits (use git bisect):**
+Already covered under Git Bisect. But delta debugging extends it: after finding the breaking commit, delta-debug the commit itself — identify which of its N changed files/lines actually causes the failure.
+
+**Over code (systematic elimination):**
+1. Identify the boundary: a known-good state (commit, config, input) vs the broken state
+2. List all differences between good and bad states
+3. Split the differences in half. Apply only half to the good state.
+4. If broken: bug is in the applied half. If not: bug is in the other half.
+5. Repeat until you have the minimal change set that causes the failure.
+
+**Over inputs:**
+1. Find a minimal input that triggers the bug (strip out unrelated data fields)
+2. The minimal input reveals which code path is exercised
+
+**When to use:**
+- "This worked yesterday, something changed" → delta debug commits
+- "Works with small data, fails with real data" → delta debug inputs
+- "Works without this config change, fails with it" → delta debug config diff
+
+**Example:** 40-file commit introduces bug
+```

+Apply first 20: still works → bug in second half.

+## Structured Reasoning Checkpoint
+
+**When:** Before proposing any fix. This is MANDATORY — not optional.
+
+**Purpose:** Forces articulation of the hypothesis and its evidence BEFORE changing code. Catches fixes that address symptoms instead of root causes. Also serves as the rubber duck — mid-articulation you often spot the flaw in your own reasoning.
+
+**Write this block to Current Focus BEFORE starting fix_and_verify:**
+
+```yaml
+reasoning_checkpoint:
+  hypothesis: "[exact statement — X causes Y because Z]"
+  confirming_evidence:
+    - "[specific evidence item 1 that supports this hypothesis]"

+  fix_rationale: "[why the proposed fix addresses the root cause — not just the symptom]"
+  blind_spots: "[what you haven't tested that could invalidate this hypothesis]"

+**Check before proceeding:**

+
+Project root: ${CWD}

+
+## Instructions
+
+1. **Invoke graphify:**
+   Run from the project root:
+   ```
+   graphify . --update
+   ```
+   This builds the knowledge graph with SHA256 incremental caching.
+   Timeout: up to 5 minutes (or as configured via graphify.build_timeout).
+
+2. **Validate output:**
+   Check that graphify-out/graph.json exists and is valid JSON with nodes[] and edges[] arrays.
+   If graphify exited non-zero or graph.json is not parseable, output:
+   ## GRAPHIFY BUILD FAILED
+   Include the stderr output for debugging. Do NOT delete .planning/graphs/ -- prior valid graph remains available.
+
+3. **Copy artifacts to .planning/graphs/:**
+   ```
+   cp graphify-out/graph.json .planning/graphs/graph.json
+   cp graphify-out/graph.html .planning/graphs/graph.html
+   cp graphify-out/GRAPH_REPORT.md .planning/graphs/GRAPH_REPORT.md
+   ```
+   These three files are the build output consumed by query, status, and diff commands.
+
+4. **Write diff snapshot:**
+   ```
+   node \"$HOME/.claude/get-shit-done/bin/gsd-tools.cjs\" graphify build snapshot
+   ```
+   This creates .planning/graphs/.last-build-snapshot.json for future diff comparisons.
+
+5. **Report build summary:**
+   ```
+   node \"$HOME/.claude/get-shit-done/bin/gsd-tools.cjs\" graphify status
+   ```
+   Display the node count, edge count, and hyperedge count from the status output.
+
+When complete, output: ## GRAPHIFY BUILD COMPLETE with the summary counts.
+If something fails at any step, output: ## GRAPHIFY BUILD FAILED with details."
+)
+```
+
+Wait for the agent to complete.
+
+---
+
+## Anti-Patterns
+
+1. DO NOT spawn an agent for query/status/diff operations -- these are inline CLI calls
+2. DO NOT modify graph files directly -- the build agent handles writes
+3. DO NOT skip the config gate check
+4. DO NOT use gsd-tools config get-value for the config gate -- it exits on missing keys

+
+`/gsd-discuss-phase` adapts its language based on your `USER-PROFILE.md`. If the profile indicates a non-technical owner — `learning_style: guided`, `jargon` listed as a frustration trigger, or `explanation_depth: high-level` — gray area questions are automatically reframed in product-outcome language instead of implementation terminology.

 Check that the plan was not too ambitious. Plans should have 2-3 tasks maximum. If tasks are too large, they exceed what a single context window can produce reliably. Re-plan with smaller scope.

+## Recommended: 1-Hour Cache TTL
+
+Use `cache_control` with a 1-hour TTL on system prompts that include GSD workflow content:
+
+```typescript
+const response = await client.messages.create({
+  model: 'claude-sonnet-4-20250514',
+  system: [
+    {
+      type: 'text',
+      text: executorPrompt, // GSD workflow instructions — large, stable across requests
+      cache_control: { type: 'ephemeral', ttl: '1h' },
+    },
+  ],
+  messages,
+});
+```
+
+### Why 1 hour instead of the default 5 minutes
+
+GSD workflows involve human review pauses between phases — discussing results, checking verification output, deciding next steps. The default 5-minute TTL expires during these pauses, forcing full re-processing of the system prompt on the next request.
+
+With a 1-hour TTL:
+
+- **Cost:** 2x write cost on cache miss (vs. 1.25x for 5-minute TTL)
+- **Break-even:** Pays for itself after 3 cache hits per hour
+- **GSD usage pattern:** Phase execution involves dozens of requests per hour, well above break-even
+- **Cache refresh:** Every cache hit resets the TTL at no cost, so active sessions maintain warm cache throughout
+
+### Which prompts to cache
+
+| Prompt | Cache? | Reason |
+|--------|--------|--------|
+| Executor system prompt | Yes | Large (~10K tokens), identical across tasks in a phase |
+| Planner system prompt | Yes | Large, stable within a planning session |
+| Verifier system prompt | Yes | Large, stable within a verification session |
+| User/task-specific content | No | Changes per request |
+
+### SDK integration point
+
+In `session-runner.ts`, the `systemPrompt.append` field carries the executor/planner prompt. When using the Claude API directly (outside the Agent SDK's `query()` helper), wrap this content with `cache_control`:
+
+```typescript
+// In runPlanSession / runPhaseStepSession, the systemPrompt is:
+systemPrompt: {
+  type: 'preset',
+  preset: 'claude_code',
+  append: executorPrompt, // <-- this is the content to cache
+}
+
+// When calling the API directly, convert to:
+system: [
+  {
+    type: 'text',
+    text: executorPrompt,
+    cache_control: { type: 'ephemeral', ttl: '1h' },
+  },
+]
+```

+# Query handler conventions (`sdk/src/query/`)
+
+This document records contracts for the typed query layer consumed by `gsd-sdk query` and programmatic `createRegistry()` callers.
+
+## Error handling
+
+- **Validation and programmer errors**: Handlers throw `GSDError` with an `ErrorClassification` (e.g. missing required args, invalid phase). The CLI maps these to exit codes via `exitCodeFor()`.
+- **Expected domain failures**: Handlers return `{ data: { error: string, ... } }` for cases that are not exceptional in normal use (file not found, intel disabled, todo missing, etc.). Callers must check `data.error` when present.
+- Do not mix both styles for the same failure mode in new code: prefer **throw** for "caller must fix input"; prefer **`data.error`** for "operation could not complete in this project state."
+
+## Mutation commands and events
+
+- `QUERY_MUTATION_COMMANDS` in `index.ts` lists every command name (including space-delimited aliases) that performs durable writes. It drives optional `GSDEventStream` wrapping so mutations emit structured events.
+- Init composition handlers (`init.*`) are **not** included: they return JSON for workflows; agents perform filesystem work.
+
+## Session correlation (`sessionId`)
+
+- Mutation events include `sessionId: ''` until a future phase threads session identifiers through the query dispatch path. Consumers should not rely on `sessionId` for correlation today.
+
+## Lockfiles (`state-mutation.ts`)
+
+- `STATE.md` (and ROADMAP) locks use a sibling `.lock` file with the holder's PID. Stale locks are cleared when the PID no longer exists (`process.kill(pid, 0)` fails) or when the lock file is older than the existing time-based threshold.
+
+## Intel JSON search
+
+- `searchJsonEntries` in `intel.ts` caps recursion depth (`MAX_JSON_SEARCH_DEPTH`) to avoid stack overflow on pathological nested JSON.
