* test(1278): RED-first descriptor parity + fail-closed guards + CHK-07 byte-stability (wave 1) - CHK-03 (RED): extend PROB-14 parity in prohibition-probe.schema.test.cjs to carry the flat check_kind/check_target/check_rule scalars through project->write->parseMustHavesBlock; the non-droppable check_kind-presence assertion is the load-bearing RED trigger (fails because projectProhibitions strips check_* on the current build). - CHK-07 (GREEN forward-guard): probe-core.test.cjs pins descriptor-less byte-stability + dispositionForProhibition fail-closed policy, with a t.todo marker forward-locking plan 01-02. - CHK-06 (RED): prohibition-enforcement.test.cjs asserts descriptorFromProjection export + fail-closed on absent/partial/unknown descriptors via the projection adapter (RED until 01-03). - No src/*.cts or .cjs edits; no new test files; lint-test-file-count clean. * feat(1278): add optional flat-scalar check descriptor fields to Prohibition interface (wave 2) - check_kind?/check_target?/check_rule? mirror CheckDescriptor.kind/target/rule (minus caller-attested failFirst, #1279) - optional so existing Prohibition consumers compile unchanged * feat(1278): project check descriptor as flat scalars in projectProhibitions (wave 2) - emit check_kind/check_target (+ check_rule only for lint-rule with a rule) when descriptor well-formed - under-specified/descriptor-less items project byte-identically (CHK-07); flat scalars ride existing parseMustHavesBlock continuation-KV path (no parser rewrite) - add CHK-02 probe-core unit cases pinning the projection - turns CHK-03 parity test GREEN; dispositionForProhibition untouched * feat(1278): descriptorFromProjection read-back adapter feeds fail-closed locate (wave 3) - Add descriptorFromProjection(projected) -> CheckDescriptor | null to src/prohibition-enforcement.cts: renames the projected flat scalars check_kind/check_target/check_rule -> {kind,target,rule?}, or null when the descriptor is absent/non-object (no check_kind key). - failFirst is NEVER sourced from the projection (stays caller-attested; #1279). - rule is set only when check_rule is a non-empty string; the adapter does NOT re-validate kind/target/rule — an under-specified descriptor reconstructs to one the EXISTING runProhibitionEnforcement LOCATE guard rejects (located:false, never green). The merged #1259 guard stays the single source of fail-closed truth. - Turns the RED CHK-06 fail-closed tests (plan 01-01) GREEN end-to-end; CHK-03 / CHK-07 stay green. CheckDescriptor type, locate guard, dispositionForProhibition, and parseMustHavesBlock are unchanged (additive +36/-0). * feat(1278): verify-phase locates prohibition check from projected descriptor (wave 3) - request.check kind/target/rule sourced from projected check_kind/check_target/check_rule via descriptorFromProjection, not verifier invention (CHK-05) - replaces the #1278 author-supplied / tracked-follow-up note with the delivered deterministic-locate behavior - preserves fail-closed routing: absent/partial descriptor -> never green, hard-gate in both modes - failFirst stays a verify-time caller attestation; #1279 bounds the remaining fail-first proof * feat(1278): spec-phase captures wired-check descriptor on test-tier resolution (wave 3) - Step 5.6 'Keep it' / verification: test path captures check_kind/check_target/check_rule, projected onto must_haves.prohibitions for verify-phase deterministic locate (CHK-04) - SOFT capture: a test-tier prohibition without a descriptor is still allowed (no hard authoring block); stays fail-closed/flagged downstream - --auto captures only an unambiguous descriptor, never fabricates a check path - failFirst NOT captured at spec-phase (verify-time attestation; #1279) - PROB-06 soft-gate + text-mode (PROB-09) behavior unchanged * chore(1278): re-baseline workflow size for grown verify-phase + spec-phase prose (wave 3) - spec-phase.md 28438 -> 30343 (+1905), verify-phase.md 35362 -> 36498 (+1136) - regenerated via npm run size:baseline (no hand-picked numbers); growth is the #1278 deterministic-locate + descriptor-capture prose - workflow-size-budget guard green (122/122) * docs(1278): ratify optional check descriptor in dated ADR-550 addendum + type:Changed changeset - Append dated 2026-06-15 ADR-550 addendum ratifying the D3 prohibition-item shape extension (optional flat-scalar check_kind/check_target/check_rule) - Document flat-scalar rationale, deterministic projection/read-back, fail-closed on partial/invalid/absent, #1279/policy out-of-scope - Add .changeset/1278-prohibition-check-descriptor.md (type: Changed) * docs(1278): document optional check descriptor in prohibition-probe reference + FEATURES - Add 'Optional wired-check descriptor (deterministic locate, #1278)' section to the prohibition-probe reference (flat-scalar keys, projection/read-back, fail-closed + backward-compat, failFirst stays attested) - Add deterministic prohibition-check descriptor source entry to FEATURES.md - No CONTEXT.md glossary change: descriptor reuses existing wired-check / verification:test vocabulary, no new glossary term introduced * fix(1278): pass packaging gates — changeset pr field + retired slash-form fix - Add required pr: 1278 to changeset (lint:changeset MISSING_PR hard requirement; plan's 'omit if unknown' was inaccurate — issue number per #1259 convention, updated to real PR number when opened) [Rule 3 - blocking] - Fix retired /gsd-spec-phase -> /gsd:spec-phase at verify-phase.md:83 (wave-3 prose; caught by slash-namespace invariant #3443/bug-2543, blocked CHK-09 full-suite-green) [Rule 1 - bug] - size:baseline + INVENTORY manifest verified in-sync post-build (no diff) * docs(1278): add check descriptor + descriptorFromProjection to CONTEXT.md prohibition glossary * fix(1278): harden descriptorFromProjection round-trip (numeric-coercion + stray-rule) per review - MD-01/LW-01: narrow projected scalars to primitives + String()-coerce, so a numeric-looking check_target (parseMustHavesBlock coerces ^\d+$ to number) reconstructs as a string and locates instead of silently un-locating; no as-string type-lie, satisfies no-base-to-string. - LW-02: attach rule only for the lint-rule kind (drop a stray node-test rule). - LW-03: document the optional check_* keys in the reference Output schema. RED->GREEN tests added in prohibition-enforcement.test.cjs. * chore(1278): set changeset pr to 1301 * test(1278): add fast-check property for the check-descriptor round-trip + fail-closed (trek-e review) RULESET.TESTS.property-based-testing: the projectProhibitions -> render -> parseMustHavesBlock -> descriptorFromProjection chain is a bijective/transformation contract. Adds 2 fc properties to tests/probe-core.property.test.cjs (no new file; ratchet stays at 2 for probe-core): - well-formed descriptors survive the round-trip across the full string domain incl. the numeric-coercion case (target/rule reconstruct as strings); - under-specified/invalid descriptors (absent / target-less / rule-less / unknown-kind) are always fail-closed (never green, flagged, unlocated). Stability is asserted at the descriptorFromProjection layer (the raw parse step is intentionally lossy for numeric scalars; the shared parser is unchanged). --------- Co-authored-by: Tom Boucher <trekkie@nomorestars.com>
Architecture Decision Records
This directory contains Architecture Decision Records (ADRs) for GSD.
Each ADR documents one architectural decision: what was decided, why, and what consequences follow. ADRs are append-only. Amendments extend existing ADRs with a dated section rather than replacing them.
Naming Convention
New ADRs use issue#-prefix slug naming:
docs/adr/<issue#>-<kebab-slug>.md
Examples: 3485-adr-prd-naming-convention.md, 3464-review-default-reviewers.md.
Why
Two developers computing "next ADR number" locally against main will independently pick the same integer and both ship. The collision is already on disk — 0010-* exists twice and 0011-* exists three times. GitHub issue numbers are server-assigned and atomic: the moment you open an issue, that number is reserved globally. Two PRs that both edit the ### Fixed block of CHANGELOG.md always conflict on merge — two PRs that each use a distinct issue# as their ADR prefix never collide. Same shape, same solution.
Legacy ADRs
Files 0001-* through 0011-* are preserved as immutable historical record. The duplicate 0010-* and the three-way 0011-* are documented residue of the old local-compute convention — not patterns to imitate. Do not renumber them.
Full process
See CONTRIBUTING.md — "Proposing an ADR or PRD" for the end-to-end workflow: opening the issue, waiting for approval, naming the file, and submitting the PR.

Seam map
ADR 0005 is the top-level SDK seam index. It references per-seam ADRs and states the narrow-waist principle each seam follows. Use it as the entry point for understanding SDK module ownership.
ADR 0006 documents how SDK query handlers project planning paths (cwd → effectiveRoot → .planning/<project>/...). Cross-reference with the Planning Workspace Module (ADR 0004) for workstream pointer policy.
ADR 0008 documents the Installer Migration Module for safe install-time moves, removals, config rewrites, and user-data preservation.
ADR 0009 documents the Shell Command Projection Module seam for runtime-aware projection of installer-owned command text and projection IR.
ADR 0010 documents the File Operation Engine Module seam for converging installer/migration/planning file mutation safety policy, and its relationship to ADR 0009 hook-command ownership policy.
ADR 0011 documents the Skill Surface Budget Module for install-time skill/agent
profile staging (--profile=<name>, .gsd-profile marker, requires: closure)
and the Phase 2 runtime /gsd:surface command for cluster-level enable/disable
without reinstall.
