Summary

gstack v2 foundation lands. Always-loaded skill catalog drops from ~9,319 to ~4,045 tokens (−56.6%), every skill gets gate-tier eval coverage (32/51 → 51/51), and three new CI budget gates catch token + dollar regressions.

This is the foundation half of the v2 launch. The architectural break (sections/*.md.tmpl pattern, mechanical Read enforcement, eval-coverage annotations) lands in v2.0.0.0 as a coordinated marketing-grade ship 2-4 weeks later. v1.45 absorbs every low-risk win, ships the eval-first floor every future skill must pass, and locks in the v1.44.1 reference baseline (test/fixtures/parity-baseline-v1.44.1.json) so reviewers can audit v1→v2 numbers against a real file.

Foundation + infra

  • v2_PLAN.md (full approved plan from /plan-ceo-review → /plan-eng-review → /codex×2 → /plan-devex-review)
  • Parity baseline capture helper + v1.44.1 snapshot locked in repo
  • ResolverEntry + appliesTo gate infrastructure in gen-skill-docs.ts
  • Cathedral parity-suite harness + 10-skill invariant registry

Compression (Phase A)

  • Jargon dedup: scripts/jargon-list.json no longer inlined into 48 skills (pointer instead)
  • Terse build flag: --explain-level=terse drops 4 preamble sections at gen time
  • Catalog trim: frontmatter description: shortens to one sentence; routing prose moves to body ## When to invoke; scripts/proactive-suggestions.json aggregates the 52-skill registry for on-demand routing access

Test floor (Phase 0)

  • test/skill-coverage-matrix.ts (51 entries) + CI gate
  • test/skill-coverage-floor.test.ts (309 structural-compliance assertions across 51 skills)
  • test/skill-size-budget.test.ts (per-skill, corpus, catalog gates)
  • test/cso-preserved.test.ts (security-prose preservation pins)
  • test/parity-suite.test.ts (cathedral content invariants)
  • test/skill-budget-regression.test.ts extended with EVALS_BUDGET_HARD_CAP (umbrella $30; gate $25; periodic $70) + EVALS_BUDGET_OVERRIDE_REASON audit trail

The numbers that matter

Source: bun run scripts/capture-baseline.ts --tag v1.45.0.0 vs test/fixtures/parity-baseline-v1.44.1.json. Reproduce with bun test test/skill-size-budget.test.ts.

The corpus barely moved because catalog trim MOVES routing prose from frontmatter to a body section — it doesn't delete it. The always-loaded surface drops by more than half because catalog text is what Claude Code reads on every session start.

Test Coverage

The v1.45 test surface (focused run):

```
1134 pass / 0 fail across 11 test files:
test/skill-validation.test.ts
test/writing-style-resolver.test.ts
test/host-config.test.ts
test/skill-size-budget.test.ts
test/parity-suite.test.ts
test/skill-coverage-matrix.test.ts
test/skill-coverage-floor.test.ts
test/cso-preserved.test.ts
test/resolver-entry.test.ts
test/helpers/capture-parity-baseline.test.ts
test/gen-skill-docs.test.ts
```

Pre-existing test pollution (not blocking): test/gstack-brain-context-load.test.ts passes in isolation (11/11) but fails when run alongside the full suite due to PATH/env pollution from a prior test. Same behavior on main — not caused by this branch. Filed as a separate known issue.

Pre-Landing Review

The v1.45 work went through five plan-mode reviews before any code landed:

  1. /plan-ceo-review (SCOPE_EXPANSION, 11/11 sections, 0 critical gaps)
  2. /codex review pass 1 (12 challenges; 7 absorbed; 3 user-decided shaped the v1.45/v2.0 hybrid split)
  3. /plan-eng-review (3 architectural decisions locked: JSON manifest, sections/*.md.tmpl pipeline, EVALS_BUDGET_HARD_CAP)
  4. /codex review pass 2 (7 additional challenges; 5 absorbed; 2 user-decided — cathedral parity-eval suite at "11" + sequential v1.45)
  5. /plan-devex-review (DX POLISH, 7.9/10 → 9.0/10, drafted JUST_UPGRADED notice + CHANGELOG numbers table + README v2 banner copy as T15 deliverables in v2_PLAN.md)

All five reviews logged at ~/.gstack/projects/garrytan-gstack/garrytan-slim-skill-tokens-reviews.jsonl.

Plan Completion

v2_PLAN.md Phase 0 + Phase A items: all DONE. Phase B (sections/*.md.tmpl pattern), Phase C (eval annotations), launch copy artifacts, migration script, README banner = deferred to v2.0.0.0 by design.

Task Status
T_DOC: docs/designs/v2_PLAN.md ✅ DONE
T0a: capture v1.44.1 baseline ✅ DONE
T0b: cathedral parity-suite harness ✅ DONE
T1: skill coverage matrix + floor ✅ DONE (51/51)
T2: ResolverEntry + appliesTo gate ✅ DONE

T5: hard token budgets + override audit ✅ DONE
T6: cso targeted dedup ✅ DONE
T7: atomic regenerate + v1.45 baseline ✅ DONE
T8: CHANGELOG + VERSION + package.json ✅ DONE

Phase B/C tasks (T9-T16) intentionally deferred to v2.0.0.0 release.

Documentation

CHANGELOG.md entry for v1.45.0.0 with the v1.44.1 → v1.45.0.0 numbers table, "what this means for you" section split for users / contributors / CI operators, and itemized Added/Changed/Fixed/For contributors sections. Voice rules honored (no em dashes, no AI vocabulary, lead with concrete numbers).

Test plan

  • bun test focused on v1.45 surface — 1134 pass, 0 fail

The approved plan from /plan-ceo-review → /plan-eng-review → /codex×2 →
/plan-devex-review. Captures the v1.45/v2.0 hybrid release shape,
cathedral parity-eval suite, sequential v1.45 execution, sections/*.md.tmpl
pipeline, EVALS_BUDGET_HARD_CAP override path, and v2 launch copy specs.

This commit just lands the design doc. Implementation follows in the rest
of the v1.45.0.0 branch.

…utility

Cathedral parity-eval suite primitive. captureBaseline() walks every
top-level SKILL.md and records bytes, lines, estimated tokens, frontmatter
description length, and eval coverage. diffBaselines() reports per-skill
delta + total corpus delta + catalog tokens delta.

Locks the v1.44.1 reference snapshot at test/fixtures/parity-baseline-v1.44.1.json.
After Phase A+B+C land, scripts/capture-baseline.ts --tag v1.45.0.0 produces
a comparable snapshot; diff supplies the real numbers the v2 CHANGELOG quotes.
Never invent baseline numbers; ship them only if they came from a real run.

v1.44.1 numbers captured this commit:
- 51 skills
- 2,847 KB total corpus
- ~9,319 catalog tokens (sum of description bytes / 4)
- top 3: ship 160 KB, plan-ceo-review 128 KB, office-hours 108 KB

Test plan:
- bun test test/helpers/capture-parity-baseline.test.ts passes 4/4
- The baseline JSON file is committed so reviewers can audit v1→v2 numbers

Adds the conditional-resolver-injection plumbing from the v2_PLAN A.1
step. Resolvers can now be either a bare ResolverFn (always fires, current
behavior) or a ResolverEntry { resolve, appliesTo? } (gated; appliesTo
returning false skips the resolver, substitutes empty string).

Why infrastructure-only: the audit during T0a confirmed most resolvers
don't need gating. The {{NAME}} placeholder system is already conditional
at the template level — a resolver only fires for skills that reference it.
The gate is for future use when a placeholder's audience needs a structural
guardrail beyond social convention, or when a sub-resolver inside a larger
composed resolver (e.g. preamble) needs per-skill skip.

scripts/gen-skill-docs.ts:444 now uses unwrapResolver() to handle both
shapes. RESOLVERS map signature widens from Record<string, ResolverFn>
to Record<string, ResolverValue>. All existing resolvers stay bare
functions and work unchanged.

Test plan:
- bun test test/resolver-entry.test.ts: 6 pass (gate plumbing + registry)
- bun test test/gen-skill-docs.test.ts: 389 pass (no regression)
- bun run gen:skill-docs --dry-run: all SKILL.md files FRESH (no diff)

A.2 jargon dedup: generate-writing-style.ts replaces the inlined 80-term
jargon list with a one-line pointer to scripts/jargon-list.json. The list
was duplicated into every tier-2+ skill (48 of 51 skills); inlining cost
was ~1.5 KB × 48 = ~70 KB across the corpus. Pointer cost is ~30 bytes per
skill. Agents Read the JSON once per session on first jargon term
encountered; thereafter the terms array is the canonical reference.

A.3 terse build flag: --explain-level=terse compresses preamble prose at
gen time. When the flag is set, writing-style collapses to a one-line
terse directive and completeness-section + confusion-protocol +
context-health are dropped entirely. The default build keeps the
runtime-conditional behavior intact (sections still render; the model
skips them when EXPLAIN_LEVEL: terse appears in the preamble echo). Terse
build is opt-in for users who want shipped skills to match their runtime
preference and avoid the per-session terse-mode dead prose.

TemplateContext gains an optional `explainLevel: 'default' | 'terse'`
field. Default builds set it to 'default'; --explain-level=terse sets
'terse'. Resolvers gate their output via `ctx?.explainLevel === 'terse'`.

Measured impact (default build, post-T3):
- Total corpus: 2,847 KB → 2,812 KB (saved 35 KB)
- ship.md: 160 → 159 KB
- plan-ceo-review.md: 128 → 127 KB
- Top 10 heaviest: all slightly smaller from jargon pointer

Larger compression lands in T4 (catalog trim) and T7 (atomic regen across
the full Phase A pipeline). The terse build path further compresses to
~711K tokens vs default ~725K (saved ~14K tokens corpus-wide).

Test plan:
- bun test test/gen-skill-docs.test.ts: 389 pass (no regression)
- bun test test/resolver-entry.test.ts: 6 pass
- bun test test/helpers/capture-parity-baseline.test.ts: 4 pass
- bun run gen:skill-docs --explain-level=terse: ship.md drops completeness +
  confusion-protocol + context-health sections; writing-style collapses to
  one-line terse directive

48 SKILL.md files updated (every tier-2+ skill picks up the jargon pointer).

…A.4)

Shortens frontmatter `description:` in every Claude SKILL.md to a single
lead sentence + (gstack) tag. The routing prose ("Use when asked to...",
"Proactively suggest...") and voice triggers move to a "## When to invoke"
body section so they remain discoverable inside the skill. A per-run
registry at scripts/proactive-suggestions.json aggregates the routing/
voice text for all 52 skills so agents can pull guidance on demand
without paying for it in the always-loaded catalog.

Build flag --catalog-mode=full restores v1.44 legacy behavior (full
multi-line descriptions in frontmatter). Default is trim.

splitCatalogDescription() extracts: lead sentence, routing paragraphs,
voice-triggers line, (gstack) tag presence. Short descriptions (<120
chars, already trimmed) are skipped via a guard so re-runs are idempotent.

Measured impact (vs v1.44.1 baseline):
- Catalog tokens (sum of description bytes / 4): 9,319 → 4,045  (-56.6%)
- Total SKILL.md corpus bytes:                   2,915 KB → 2,880 KB (-1.2%)
- Routing prose preserved as in-skill "## When to invoke" sections
- 52 skill entries in scripts/proactive-suggestions.json (on-demand registry)

The corpus drop is small because catalog trim MOVES text from frontmatter
to body, it doesn't delete it. The headline win is the catalog: the
always-loaded system prompt surface drops by more than half.

Test plan:
- bun test test/gen-skill-docs.test.ts: 389 pass, 0 fail
- Manual: ship/SKILL.md frontmatter description is now ONE line ending
  with `(gstack)`; allowed-tools field on next line (YAML well-formed)
- Manual: scripts/proactive-suggestions.json contains 52 entries
- bun run gen:skill-docs --catalog-mode=full restores legacy behavior

53 files changed (52 SKILL.md across hosts + the new proactive-suggestions.json).

Two new gate-tier guardrails for the v1.45.0.0 compression baseline:

1. test/skill-size-budget.test.ts (NEW) — per-skill SKILL.md size budget.
   Compares current state to test/fixtures/parity-baseline-v1.44.1.json.
   Three checks: per-skill (×1.05 default ratio), total corpus, and
   catalog token estimate (≤7000 for v1.45). The per-skill ratio is 1.05
   not 1.0 because the T4 catalog trim moves text from frontmatter to a
   body section; small skills see a tiny body growth that's fine when
   offset by the much larger catalog-token win.

2. test/skill-budget-regression.test.ts EXTENDED — hard dollar cap on
   per-run eval cost. Per-tier defaults: gate $25, periodic $70. Umbrella
   EVALS_BUDGET_HARD_CAP=$30. Catches runaway eval costs (infinite retry,
   model price changes) before they amortize across PRs.

Both checks support an override path with audit trail:
   GSTACK_SIZE_BUDGET_OVERRIDE_REASON="why this is OK"   — size
   EVALS_BUDGET_OVERRIDE_REASON="why this is OK"          — cost
Overrides log to ~/.gstack/analytics/spend-overrides.jsonl with
timestamp + scope + reason + CI provenance (runner, branch, commit)
via test/helpers/budget-override.ts.

Why the override audit: a hard cap with no escape valve becomes
operationally hostile (legit price changes, longer transcripts, new
required evals can all blow the cap). An override with no audit becomes
"everyone overrides everything and the gate is theater." This module
ships the audit half so reviewers can see what was waived and why.

Codex 2nd-pass critique #3 absorbed: per-suite caps + override path with
auditability + budget baselines checked into repo (parity-baseline-v1.44.1.json
already in test/fixtures/).

Test plan:
- bun test test/skill-size-budget.test.ts: 4 pass (per-skill, corpus, catalog, baseline-exists)
- bun test test/skill-budget-regression.test.ts: 4 pass (2 existing ratio checks + 2 new hard-cap checks)
- Existing eval runs ($14.11 e2e, $0.02 llm-judge) sit well under the new caps

cso/SKILL.md is a content-heavy security audit skill (75 KB after T3+T4).
Codex 2nd-pass critique #9: "cso exemption too broad ... should still get
resolver dedup, catalog trim, sectioning if safe, and targeted evals
around must-not-miss checks."

T3 (jargon dedup) and T4 (catalog trim) already applied to cso the same
way they applied to every other skill — confirmed by inspection:
- jargon list NOT inlined (0 inline term lines)
- catalog description trimmed to one line (74 bytes vs 774 bytes baseline)
- "## When to invoke" body section present

T6 work: lock in the security-prose preservation via a gate-tier test
that fails CI if future compression strips load-bearing phrases:
- OWASP, STRIDE positioning
- daily / comprehensive mode discipline
- confidence scoring language
- active verification ("verif" prefix catches verify/verified/verification)
- ## Preamble heading (preamble resolver still fires)

Also guards cso against accidental over-stripping: SKILL.md must stay
≥30 KB (currently 75 KB) — a sudden cliff would mean compression went
past the targeted-dedup line into structural removal.

No structural change to cso. Future Phase B sections/ work for cso
requires writing baseline parity tests FIRST per the v2_PLAN.md
sequencing.

Test plan:
- bun test test/cso-preserved.test.ts: 5 pass

Adds the harness that the v2_PLAN.md cathedral parity-eval suite is built
on. Compares CURRENT SKILL.md output to v1.44.1 baseline along three axes:

  STRUCTURE  frontmatter shape (catalog trim landed, "## When to invoke" present)
  CONTENT    must-preserve phrases per skill family (cso: OWASP/STRIDE;
             plan-ceo: SCOPE EXPANSION/HOLD SCOPE/REDUCTION; ship:
             VERSION/CHANGELOG/PR; etc.)
  SIZE       per-skill byte budget (maxSizeRatio + minBytes guards)

PARITY_INVARIANTS registry pins 10 load-bearing skills (cso, ship, plan-*-
review, review, qa, investigate, office-hours, autoplan). Each entry
declares what must NOT regress; future compression that strips these
phrases or shrinks a skill past its minBytes cliff fails CI.

Periodic-tier LLM-judge parity (paid, ~$0.20/skill) lands in v2.0.0.0
sections/ phase. Same registry, same harness, judge added on top.

Test plan:
- bun test test/parity-suite.test.ts: 10/10 invariants pass vs v1.44.1
- Per-skill failures get actionable per-line breakdown so a reviewer can
  see which phrase / heading / size limit went sideways

Phase 0 deliverable — eval-first foundation. Two new test files plus the
registry:

1. test/skill-coverage-matrix.ts — single source of truth mapping each
   skill to its gate-tier + periodic-tier test files. SKILL_COVERAGE
   record with 51 entries; every gstack skill on disk has at least one
   gate-tier entry.

2. test/skill-coverage-matrix.test.ts — CI gate. Asserts every skill on
   disk has a registry entry AND that gate[] is non-empty. Catches
   "skill added but eval not registered" the moment a new SKILL.md
   lands.

3. test/skill-coverage-floor.test.ts — per-skill structural compliance
   (FREE, file-IO only). For each of 51 skills, verifies:
   - SKILL.md exists
   - Frontmatter well-formed (name + description fields)
   - Catalog-trim contract (inline description ≤ 250 chars, or block form)
   - Generated header present (edit .tmpl, not .md)
   - Body ≥ 200 bytes (non-trivial content)
   - No unresolved {{TEMPLATE}} placeholders leaked

The "floor" is the minimum eval that every skill ships with. Skills that
need deeper behavioral testing get additional entries in their coverage
record (e.g., ship has skill-e2e-ship-idempotency + workflow + floor).
Future skills only need to add the floor entry and the matrix gate
unblocks them.

Codex 2nd-pass critique #1 mitigation: eval-first floor is structural
compliance (the testable part) — judgment-skill behavior gets layered
periodic-tier evals on top. We don't pretend the floor proves
correctness, only that the skill structurally compiles.

Test plan:
- bun test test/skill-coverage-matrix.test.ts: 4 pass (matrix shape + coverage)
- bun test test/skill-coverage-floor.test.ts: 309 pass (6 checks × 51 skills + 3 registry-level)

Final regen pass across all hosts after T1-T6 work landed. Captures the
v1.45.0.0 parity baseline at test/fixtures/parity-baseline-v1.45.0.0.json
for diffing against the v1.44.1 reference.

Measured deltas (real numbers from test/helpers/capture-parity-baseline.ts):

  Total SKILL.md corpus       2,847 KB → 2,813 KB        (-1.2%)
  Catalog tokens (always-loaded) ~9,319 → ~4,045 tokens   (-56.6%)
  Top 10 heaviest skills      0.5-1.0% drop each

The catalog token cut is the headline. It's the always-loaded surface,
i.e. tokens charged on every session start. Per-skill SKILL.md sizes
barely moved because T4 catalog trim MOVES routing prose from frontmatter
to a body "## When to invoke" section rather than deleting it — the
catalog wins without amputating discoverability.

The bigger per-skill compression lands in v2.0.0.0 (Phase B sections/
pattern on the 5 heavyweights). v1.45 is the foundation: eval-first
infrastructure + cheap wins.

scripts/proactive-suggestions.json regenerated with the latest 52 skills
listed (one-time write per gen-skill-docs run; aggregated catalog parts).

… floor

Bumps VERSION + package.json to 1.45.0.0. CHANGELOG entry covers what
shipped between v1.44.1 and this release: the cathedral parity-eval
foundation, conditional resolver injection plumbing, jargon dedup, terse
build flag, catalog trim with one-line frontmatter descriptions, hard
token + dollar budget gates with override audit, cso preservation pins,
and the v1.44.1 ↔ v1.45.0.0 parity baselines committed to test/fixtures/.

Numbers (measured, not estimated):
- Catalog tokens: ~9,319 → ~4,045  (-56.6%)
- Total corpus:   2,847 KB → 2,813 KB (-1.2%)
- Skills with gate-tier eval coverage: 32/51 → 51/51 (floor achieved)

This is the foundation release. v2.0.0.0 will ship the architectural
break (sections/*.md.tmpl pattern + mechanical Read enforcement +
eval-coverage annotations) as a coordinated marketing-grade launch.

….45 bump

The generated_at field updates on every gen-skill-docs run; this is the

…mestamp)

Original implementation wrote a generated_at timestamp on every gen-skill-docs
run. That made CI dry-run freshness checks flap because the file changed on
every regeneration even when the actual content (skill descriptions, routing
prose, voice triggers) was unchanged.

Two fixes:
1. Drop the generated_at field. The file is purely a content registry now.
2. Only write the file when serialized content actually differs from disk.

Reproducible test: bun run gen:skill-docs twice in a row now leaves
scripts/proactive-suggestions.json unchanged on the second run.

…chars

splitCatalogDescription truncated the lead BEFORE computing routing
extraction, which meant skills whose first sentence was over 200 chars
(design-consultation: 207 chars) had their entire routing prose silently
dropped — the "## When to invoke" body section came out empty.

Root cause: routing was extracted via `collapsed.indexOf(lead)` after lead
was suffixed with "...". The "..." never appeared in the original string,
so indexOf returned -1 and routingProse fell back to empty.

Fix: compute routing from sentenceLead (the untruncated first sentence)
BEFORE truncating the displayed lead. The displayed lead still gets "..."
when over 200 chars, but the routing extraction uses the real boundary.

Also: refresh golden snapshots for claude/codex/factory ship and update
two unit tests that asserted v1.44 behavior:
- skill-validation.test.ts: trigger-phrase + proactive-routing tests now
  search whole content, not just frontmatter (T4 moved them to a body
  "## When to invoke" section)
- writing-style-resolver.test.ts: jargon-list assertion now expects the
  T3 reference pointer, not the inline list

Main shipped v1.45.0.0 (persistent design daemon) at cf50443 while this
branch was at v1.45.0.0 (gstack v2 foundation). Same-MINOR-bump-level
queue collision per CLAUDE.md versioning invariant — advance this branch
to v1.46.0.0 to claim the next slot.

Resolved CHANGELOG.md conflict: kept both v1.45.0.0 (design daemon, main)
and v1.46.0.0 (gstack v2 foundation, this branch) entries in
reverse-chronological order. Updated VERSION, package.json, and renamed
test/fixtures/parity-baseline-v1.45.0.0.json → -v1.46.0.0.json with the
internal tag field synced.

Updated CHANGELOG entry numbers-table column header from v1.45.0.0 to
v1.46.0.0 + the source-reproduction line + the "v1.45 absorbs..." prose
and the eval target reference in skill-size-budget.test.ts comment.

Auto-merged main's design-daemon SKILL.md changes for design-consultation,
design-shotgun, office-hours, plan-design-review. Regenerated all SKILL.md
files via gen-skill-docs --host all to ensure clean state. Refreshed golden

CI check-freshness failed because scripts/proactive-suggestions.json
serialized differently on local vs CI:

1. Root-skill key leaked the directory name. processTemplate's outer loop
   computed `dir = path.basename(path.dirname(tmplPath))`. For the root
   SKILL.md.tmpl at ROOT/SKILL.md.tmpl, that returns the repo-checkout
   directory name — "seville-v3" in a Conductor worktree, "gstack" on
   GitHub Actions, anything-else for a fork. Fix: detect root via
   `path.dirname(tmplPath) === ROOT` and hardcode the key to "gstack"
   for that one case.

2. Aggregate key order was filesystem-iteration order. discoverTemplates
   doesn't guarantee stable ordering across platforms, so the JSON
   `skills` object came out shuffled between machines. Fix: sort
   Object.keys(proactiveAggregate) alphabetically before serializing.

After the fix, the generated file is identical on every machine and
matches what's committed. CI freshness check (bun run gen:skill-docs &&
git diff --exit-code) now passes.

Test plan:
- bun run gen:skill-docs && bun run gen:skill-docs --dry-run: all FRESH
- node -e 'verify keys sorted': sorted match: true
- grep -c '"seville-v3"' scripts/proactive-suggestions.json: 0
- Focused test suite: 704 pass, 0 fail

Four exported functions in scripts/gen-skill-docs.ts handle every skill's
frontmatter rewrite at gen time but had zero unit tests. Both real bugs we
shipped (and fixed) on this branch lived in these functions:

  v1.45.0.0 design-consultation: when the first sentence exceeded 200 chars,
  routing-prose extraction lost the entire tail (anchored on truncated lead
  with "..." that didn't substring-match the original).

  v1.45.0.0 CI freshness: root-skill key leaked the checkout directory
  name ("seville-v3" vs "gstack") and aggregate order was filesystem-
  iteration order.

Both shapes are now regression-tested:

- splitCatalogDescription: 7 tests covering simple multi-line, >200-char
  first sentence (design-consultation regression), voice-trigger
  extraction, no-(gstack) handling, embedded periods (documents known
  fallback), no-period fragments, and idempotency.
- buildTrimmedDescription: 3 tests.
- buildWhenToInvokeSection: 3 tests.
- applyCatalogTrim: 4 tests covering the standard rewrite, no-op for
  already-short descriptions, the YAML-collision newline fix, and the
  malformed-frontmatter null return.
- proactive-suggestions.json determinism: 3 tests asserting sorted keys,
  root keyed as "gstack" (not the worktree directory), and no
  timestamp/generated_at field that would flap CI freshness.

Test plan:
- bun test test/catalog-trim.test.ts: 20 pass, 0 fail

Three untested surfaces from the v1.46.0.0 work. All three would have
caught real bugs we shipped (and fixed) on this branch.

1. test/helpers/budget-override.test.ts — 7 tests pin the audit-trail
   contract for EVALS_BUDGET_OVERRIDE_REASON and
   GSTACK_SIZE_BUDGET_OVERRIDE_REASON. Without this, the audit logger
   could silently drop events and overrides become invisible. Tests
   cover: required fields per JSONL line, CI provenance capture
   (CI/GITHUB_ACTIONS/branch/commit), local-runner defaults,
   append-only behavior, missing-directory recovery, and unwritable-
   path resilience (logs warning instead of throwing).

2. test/terse-build.test.ts — 16 tests pin --explain-level=terse
   behavior across the 4 gated resolvers and the composed preamble.
   Default vs terse vs undefined-ctx all asserted. Without this, a
   refactor that breaks the explainLevel threading silently regresses
   the opt-in compression path; the runtime EXPLAIN_LEVEL: terse gate
   still works so users wouldn't notice. Tier-1 invariant pinned
   (terse-only-affects-tier-2+).

3. test/gen-skill-docs-idempotency.test.ts — 2 tests catch the class
   of bug behind the v1.45.0.0 timestamp flap. Two consecutive
   gen-skill-docs runs must produce byte-identical outputs across
   STABLE_OUTPUTS (proactive-suggestions.json, SKILL.md, ship/SKILL.md,
   plan-ceo-review/SKILL.md, office-hours/SKILL.md, gstack/llms.txt).
   --dry-run reports zero stale files after a fresh gen. CI freshness
   regressions surface as test failures BEFORE a PR is opened.

Test plan:
- bun test test/helpers/budget-override.test.ts: 7 pass
- bun test test/terse-build.test.ts: 16 pass
- bun test test/gen-skill-docs-idempotency.test.ts: 2 pass
- Full focused suite (15 test files): 1179 pass, 0 fail (+45 new tests
  vs the pre-fill baseline of 1134)

Five behaviors that v1.46 ships but had no test coverage. All now pinned.

A) --host all idempotency (test/gen-skill-docs-idempotency.test.ts)
   The default test ran Claude host only. Non-Claude hosts (Codex, Factory,
   Cursor, OpenClaw, GBrain, Slate, OpenCode, Hermes, Kiro) each have their
   own output paths and could carry their own non-deterministic fields. We
   hit a "--host all needed for freshness check" mid-/ship. Now: two
   consecutive `bun run gen:skill-docs --host all` runs must produce
   byte-identical outputs across a per-host sample (.agents/, .cursor/,
   .factory/, .gbrain/). Catches per-host adapter regressions before CI.

B) --catalog-mode=full opt-out (test/catalog-mode-full.test.ts)
   The legacy escape hatch had zero tests. 6 new tests across two layers:
   static (CATALOG_MODE_ARG parsed; conditional gate present; default is
   "trim"; invalid value throws) + smoke (actual --catalog-mode=full run
   produces a multi-line `description: |` block + omits "## When to invoke"
   body section; mutates the working tree then restores in a finally block).

C) parity-baseline-v1.44.1.json integrity (test/parity-baseline-integrity.test.ts)
   The baseline is the source of every v1→v2 number cited in the
   CHANGELOG v1.46.0.0 entry. Anyone could edit it without test failure
   until now. 8 new tests pin: existence, tag, capturedFromCommit
   allowlist, expected v1.44 numbers (51 skills, ~2,915 KB, ~9,319
   catalog tokens), CHANGELOG references this file by path, per-skill
   shape, and a SHA256 byte-stability hash. Any edit fails with a clear
   "if intentional, update EXPECTED_HASH AND the CHANGELOG numbers" signal.

D) Live appliesTo gate end-to-end (test/resolver-entry.test.ts extended)
   The unwrapResolver unit tests covered the function; the gen-skill-docs.ts
   substitution loop that USES the gate had no integration coverage. 6 new
   tests simulate the exact 4-line shape from gen-skill-docs.ts:457-467
   against synthetic registries: plain-function fires unconditionally,
   gated fires when true / empty-string when false, mixed registries
   compose, parameterized resolvers respect gates, unknown resolvers throw.

E) Per-skill min-size floor (test/skill-size-budget.test.ts extended)
   The existing 200-byte body coverage-floor is a noise floor — a skill
   that lost 99.75% of content still passes. 1 new test asserts every
   skill stays ≥80% of its v1.44.1 baseline size (the parity-suite
   content invariants only covered 10 of 51 skills; the remaining 41
   were uncovered). SECTIONS_EXTRACTED hook in place for v2.0.0.0 when
   the sections/ pattern legitimately shrinks ship/plan-ceo/etc. past
   the floor.

Test plan:
- bun test focused 17-file suite: 1202 pass, 0 fail
  (+23 new tests vs the pre-fill 1179 baseline)
- catalog-mode=full mutates working tree then restores cleanly
- --host all idempotency runs two full gen passes in <1s on this machine
