Handover: Parity exceptions doc + CJS-only matrix (next session)

Status: The deliverables described below are implemented in sdk/src/query/QUERY-HANDLERS.md (sections Golden parity: coverage and exceptions and CJS command surface vs SDK registry). Use that file as the canonical registry + parity reference; this handover remains useful for issue #2302 scope and parent #2007 links.

Paste this document (or @sdk/HANDOVER-PARITY-DOCS.md) at the start of a new chat so work continues without re-auditing issue scope.

Goal for this session

1. Parity “exceptions” documentation — A clear, maintainable description of where full JSON equality between gsd-tools.cjs and createRegistry() is not expected or not attempted, and why (stubs, structural-only tests, environment-dependent fields, ordering, etc.). Map this to #2007 / #2302 expectations: no undocumented gap.
2. CJS-only matrix — A single authoritative table: each relevant gsd-tools.cjs surface (top-level command or documented cluster) → registered in SDK vs permanent CLI-only vs alias / naming difference, with a one-line justification where not registered.

Parent tracking

• Issue: open-gsd/get-shit-done-redux#2302 — Phase 3 SDK query parity, registry, docs (parent umbrella #2007).
• Acceptance criteria touched here: parity coverage/exceptions documented; registry audit reflected in a matrix (issue wording: “every required CJS surface either has a handler or appears in the CJS-only matrix with justification”).

Repo / branch

• Workspace: D:\Repos\get-shit-done (PBR backport); adjust path if different machine.
• Feature branch (typical): feat/sdk-phase3-query-layer — confirm with git branch before editing.
• Upstream: open-gsd/get-shit-done-redux.

What already exists (do not duplicate blindly)

• sdk/src/query/QUERY-HANDLERS.md — Registry conventions, partial “not registered” list (graphify, from-gsd2), CLI name differences (summary-extract vs summary.extract, scaffold vs phase.scaffold), intel.update (CJS JSON parity; refresh via agent), skill-manifest --write / mutation events, docs-init golden note (agent install fields), stateExtractField rule.
• sdk/src/golden/golden.integration.test.ts — Source of truth for which commands are golden-tested and how (full equality vs subset vs normalized existing_docs vs omitted fields; init.quick strips clock-derived keys via init-golden-normalize.ts).
• sdk/src/golden/capture.ts — captureGsdToolsOutput() spawns get-shit-done/bin/gsd-tools.cjs.
• docs/CLI-TOOLS.md — User-facing CLI reference; should link to the parity exceptions + matrix (or host a short summary with pointer to sdk/).

Deliverables (suggested shape)

A) Parity exceptions section

Add or extend a dedicated section (prefer QUERY-HANDLERS.md under a heading like "Golden parity: coverage and exceptions", or a new sdk/PARITY.md if the team wants less churn in QUERY-HANDLERS — pick one canonical location and link from the other).

Cover at least:

Category	Examples to document
Full JSON parity	Commands where tests use toEqual on sdkResult.data vs CJS stdout JSON.
Structural / field subset	Tests that compare only selected keys (e.g. frontmatter.get, find-phase — SDK subset vs CJS). Full parity for roadmap.analyze, init.* (except init.quick volatile keys), etc. — see QUERY-HANDLERS.md matrix.
Normalized comparison	e.g. docs-init: existing_docs sorted by path; agents_installed / missing_agents omitted between subprocess vs in-process.
CLI parity without in-process refresh	intel.update — JSON matches CJS intel.cjs (spawn hint or disabled); refresh is agent-driven.
Conditional behavior	skill-manifest: writes only with --write; not in QUERY_MUTATION_COMMANDS.
Environment / time	current-timestamp: structure and format, not same instant.
Not in golden suite	Commands registered but not (yet) covered — list as coverage gap or out of scope for golden with rationale.

B) CJS-only matrix

Build the table by diffing get-shit-done/bin/gsd-tools.cjs switch (command) top-level cases against createRegistry() registrations in sdk/src/query/index.ts.

Already documented as product-out-of-scope for registry: graphify, from-gsd2 / gsd2-import.

Already documented as naming/alias differences (registered, different string): summary-extract ↔ summary.extract; top-level scaffold ↔ phase.scaffold.

Matrix columns (suggested):

• CJS command (or subcommand pattern)
• SDK dispatch name(s) if any
• Disposition: Registered / CLI-only / Alias-only / Stub / N/A
• Justification (one line) if not a straight registered parity

Optional: footnote that detect-custom-files skips multi-repo root resolution in CJS (SKIP_ROOT_RESOLUTION) — behavior is documented in CLI; matrix can mention if relevant.

Files likely to edit

Path	Role
sdk/src/query/QUERY-HANDLERS.md	Primary home for exceptions + matrix, or link hub.
sdk/PARITY.md	Optional dedicated file if QUERY-HANDLERS becomes too long.
docs/CLI-TOOLS.md	Short “Parity & registry” subsection with links into sdk/ docs.
sdk/HANDOVER-GOLDEN-PARITY.md	Optional one-line pointer to new parity doc section when done.

Out of scope for this handover session

• Implementing runner alignment (GSDTools → registry) — separate #2302 work.
• Adding @deprecated headers to gsd-tools.cjs — separate task.
• CHANGELOG — only if you batch doc work with release notes in same PR (optional).

Verification

• No code behavior change required for pure docs; run npm run build in sdk/ only if TypeScript-adjacent files were touched.
• Proofread: every CLI-only row has a justification; every exception in golden tests appears in the exceptions doc.

Success criteria

• A reader can answer: “Which commands are fully golden-parity vs partial vs stub vs untested?” without reading the whole test file.
• A reader can answer: “Which gsd-tools top-level commands are not registered and why?” from one table.
• #2302 acceptance bullets on parity documentation and registry matrix are satisfied for the documentation slice (remaining issue items may still be open for code).

Created for handoff to “parity exceptions + CJS-only matrix” session. Update when the canonical doc location or golden coverage changes.
