* 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).
