Handover: SDK query layer (registry, CLI, parity docs)

Paste this document (or @sdk/HANDOVER-QUERY-LAYER.md) at the start of a new session so work continues without re-deriving scope.

Parent tracking

• Issue: open-gsd/get-shit-done-redux#2302 — Phase 3 SDK query parity, registry, docs (umbrella #2007).
• Workspace: D:\Repos\get-shit-done (PBR backport). Upstream: open-gsd/get-shit-done-redux. Confirm branch with git branch (typical: feat/sdk-phase3-query-layer).

Scope anchors (do not confuse issues)

Role	GitHub	Notes
Product / requirements anchor	#2007	Problem statement, user stories, and target architecture for the SDK-first migration. Do not treat its original acceptance-checklist boxes as proof of what is merged upstream; work was split into phased PRs after maintainer review.
Phase 3 execution scope	#2302 + this handover	What this branch is actually doing now: registry/CLI parity, docs, harness gaps, runner alignment follow-ups as listed below.
Patch mine (if local tree is short)	PR #2008 and matching branches	Large pre-phasing PR; cherry-pick or compare when something looks missing vs that line of work.

What was delivered (this line of work)

1. Parity documentation (QUERY-HANDLERS.md)

• ”Golden parity: coverage and exceptions” — How golden.integration.test.ts compares SDK vs gsd-tools.cjs (full toEqual, subset, normalized docs-init, intel.update CJS parity, time-dependent fields, etc.).
• ”CJS command surface vs SDK registry” — Naming aliases, CLI-only rows, SDK-only rows, and a top-level gsd-tools command → SDK matrix.
• docs/CLI-TOOLS.md — Short “Parity & registry” pointer into those sections.
• HANDOVER-GOLDEN-PARITY.md — One paragraph linking to the same sections.

2. gsd-sdk query tokenization (normalizeQueryCommand)

• Problem: gsd-sdk query used only argv[0] as the registry key, so query state json dispatched state (unregistered) instead of state.json.
• Fix: sdk/src/query/normalize-query-command.ts merges the same command + subcommand patterns as gsd-tools runCommand() (e.g. state json → state.json, init execute-phase 9 → init.execute-phase, scaffold … → phase.scaffold, progress bar → progress.bar). Wired in sdk/src/cli.ts before registry.dispatch().
• Tests: sdk/src/query/normalize-query-command.test.ts.

3. phase add-batch in the registry

• Implementation: phaseAddBatch in sdk/src/query/phase-lifecycle.ts — port of cmdPhaseAddBatch from get-shit-done/bin/lib/phase.cjs (batch append under one roadmap lock; sequential or phase_naming: custom).
• Registration: phase.add-batch and phase add-batch in sdk/src/query/index.ts; listed in QUERY_MUTATION_COMMANDS (dotted + space forms).
• Tests: describe('phaseAddBatch') in sdk/src/query/phase-lifecycle.test.ts.
• Docs: QUERY-HANDLERS.md updated — phase add-batch is registered; CLI-only table no longer lists it.

4. state load fully in the registry (split from state json)

Previously state.json and state.load were easy to confuse: CJS has two different commands — cmdStateJson (state json, rebuilt frontmatter) vs cmdStateLoad (state load, loadConfig + state_raw + existence flags).

• stateJson — sdk/src/query/state.ts; registry key state.json.
• stateProjectLoad — sdk/src/query/state-project-load.ts; registry key state.load. Uses createRequire to call core.cjs loadConfig(projectDir) from the same resolution paths as a normal install (bundled monorepo path, projectDir/.claude/get-shit-done/..., ~/.claude/get-shit-done/...). GSDTools.stateLoad() and formatRegistryRawStdout for --raw no longer force a subprocess solely for this command.
• Risk: If core.cjs is absent (e.g. some @opengsd/gsd-sdk-only layouts), state.load throws GSDError — document; future option is a TS loadConfig port or bundling.
• Goldens: read-only-parity.integration.test.ts — one block compares state.json to state json (strip last_updated); another compares state.load to state load (full toEqual). read-only-golden-rows.ts readOnlyGoldenCanonicals() includes both state.json and state.load.

Query surface completeness (snapshot)

Status	Surface
Registered	Essentially all gsd-tools.cjs runCommand surfaces, including phase.add-batch.
CLI-only (by design)	graphify, from-gsd2 — not in createRegistry(); documented in QUERY-HANDLERS.md.
SDK-only extra	phases.archive — no gsd-tools phases archive subcommand (CJS has list / clear only).

Programmatic API: createRegistry() / registry.dispatch('dotted.name', args, projectDir).

CLI: gsd-sdk query … — apply normalizeQueryCommand semantics (or pass dotted names explicitly).

Still not unified: GSDTools (sdk/src/gsd-tools.ts) shells out to gsd-tools.cjs for plan/session flows; migrating callers to the registry is separate #2302 / runner work. state load is not among the subprocess-only exceptions anymore (it uses the registry like other native query handlers when native query is active).

Roadmap: parity vs decision offloading

Work that moves deterministic orchestration out of AI/bash and into SDK queries (historically gsd-tools.cjs) has two layers. Do not confuse them:

Layer	Goal	What “done” looks like
Parity / migration	Existing CLI behavior is stable and testable in the registry so callers can use gsd-sdk query instead of node …/gsd-tools.cjs without silent drift.	Goldens + QUERY-HANDLERS.md; same JSON/--raw contracts as CJS.
Offloading decisions	New or consolidated queries replace repeated grep, ls piped to wc -l, many config-gets, and inline node -e in workflows — so the model does less parsing and branching.	Fewer inline shell blocks; measurable token/step reduction on representative workflows.

Phase 3–style registry work mainly advances parity. The decision-routing-audit.md proposals are mostly offloading — they assume parity exists for commands workflows already call.

Decision-routing audit (proposed gsd-tools / SDK queries)

Source: .planning/research/decision-routing-audit.md §3. Tier = priority from §5 (implementation order). Do not implement = explicitly rejected in the audit.

#	Proposed command	Tier	Notes
3.1	route next-action	1	Next slash-command from /gsd-next-style routing.
3.2	check gates <workflow>	3	Safety gates (continue-here, error state, verification debt).
3.3	check config-gates <workflow>	1	Batch workflow.* config for orchestration (replaces many config-gets).
3.4	check phase-ready <phase>	1	Phase directory readiness + next_step hint.
3.5	check auto-mode	2	auto_advance + _auto_chain_active → single boolean.
3.6	detect phase-type <phase>	2	Structured UI/schema detection (replaces fragile grep).
3.7	check completion <scope>	2	Phase or milestone completion rollup.
3.8	check verification-status <phase>	3	VERIFICATION.md parsing for routing.
3.9	check ship-ready <phase>	3	Ship preflight (ship.md).
3.10	route workflow-steps <workflow>	❌ Do not implement	Pre-computed step lists are unsound when mid-workflow writes change state. See review-and-risks.md §3.6.

Not in audit: phase-artifact-counts was only an example in an older handover line; there is no §3.11 for it — add via a new research doc if needed.

SDK registry (Tier 1): Done — check.config-gates, check.phase-ready, route.next-action in createRegistry() (sdk/src/query/index.ts). Documented in sdk/src/query/QUERY-HANDLERS.md § Decision routing (SDK-only until/unless mirrored in gsd-tools.cjs).

Simple roadmap (execute in order):

1. Harden parity for surfaces workflows already depend on (registry dispatch, goldens, docs) so swaps from CJS to gsd-sdk query stay safe.
2. Ship 1–2 high-leverage consolidation handlers from the audit (pick based on impact and risk; examples: check auto-mode, phase-artifact-counts, route next-action — with display/routing fields required by review-and-risks.md if applicable). Each needs handlers, tests, and QUERY-HANDLERS.md notes. Progress: check.auto-mode shipped (sdk/src/query/check-auto-mode.ts); Tier 1 route.next-action already registered.
3. Rewrite one heavy workflow (e.g. next.md or a focused slice of autonomous.md) to consume those queries and measure before/after (steps, tokens, or both). Progress: execute-phase.md, discuss-phase.md, discuss-phase-assumptions.md, and plan-phase.md (UI gate) now use check auto-mode instead of paired config-gets where applicable.
4. Maintain a living boundary between SDK (data, deterministic checks) and workflows (judgment, sequencing, user-facing messages). Extend decision-routing-audit.md §6 (decisions that stay with the AI) and review-and-risks.md “Do not implement” (e.g. no pre-computed route workflow-steps) as you add primitives. Progress: audit §3.5 / Tier 2 #4 updated to reference SDK implementation.

Gaps to keep in mind when designing new queries: call-time vs stale data after file writes (re-query volatile fields); workflows own gates/UX; behavioral contracts (e.g. UI keyword lists) must match existing greps; stderr/stdout and JSON shapes stable for bash/jq; hybrid require(core.cjs) paths called out for minimal installs.

Research references (repo root): .planning/research/decision-routing-audit.md, .planning/research/review-and-risks.md, .planning/research/inline-computation-audit.md, .planning/research/questions.md (Q1 boundary). For parity mechanics, prefer sdk/src/query/QUERY-HANDLERS.md and HANDOVER-GOLDEN-PARITY.md.

Suggested next session

(Strategic ordering of parity vs decision offloading is in Roadmap above.)

1. Golden test for phase.add-batch — Done: sdk/src/golden/mutation-subprocess.integration.test.ts (phase.add-batch JSON parity vs CJS).
2. Re-export normalizeQueryCommand — Done: exported from sdk/src/query/index.ts and sdk/src/index.ts (@opengsd/gsd-sdk).
3. Issue #2302 follow-ups — Runner alignment (GSDTools → registry where appropriate). configGet now uses dispatchNativeJson with canonical config-get (fixes subprocess argv vs real gsd-tools.cjs, which has no config + get top-level). Keep graphify / from-gsd2 out of scope unless product reopens.
4. Drift check — When adding CJS commands, update QUERY-HANDLERS.md matrix and golden docs in the same PR.

Verification commands

cd sdk
npm run build
npx vitest run src/query/normalize-query-command.test.ts src/query/phase-lifecycle.test.ts src/query/registry.test.ts --project unit
npx vitest run src/golden/golden.integration.test.ts --project integration

(Adjust --project to match sdk/vitest.config.ts.)

Success criteria (query-layer slice)

• Parity expectations and CJS↔SDK matrix documented in one place (QUERY-HANDLERS.md).
• gsd-sdk query understands two-token command patterns like gsd-tools.
• phase add-batch implemented and registered; only intentional CLI-only gaps remain (graphify, from-gsd2).

Created/updated for query-layer handoff. Revise when registry surface, golden coverage, or the parity/offloading roadmap changes materially.
