c899f5ada3 chore(#3065): build the deterministic load-bearing-fragment contract gate (#3068)
* test(#3065): build the load-bearing contract gate ADR-1671 promised

Epic #1671 Phase 7. A post-merge audit of every promise in ADR-1671 against the
merged tree found one mitigation asserted-but-absent and two stale records.

ADR-1671 names exactly one correctness risk — trimming a load-bearing fragment,
with the recorded history of a paraphrased META.RULE causing agent violations —
and #2931 amended its mitigation to a deterministic contract gate that proves no
load-bearing fragment was omitted or shrunk, treats a floored fragment as a
success, and asserts the isolate prefix survives byte-identical, with an explicit
anti-vacuity rule.

That gate did not exist. What existed was tests/context-composer.test.cjs:
synthetic unit tests of the composeWithinBudget primitive over invented
fragments, asserting nothing about real declared strategies. The ADR asserted a
mitigation that was never built, which is the promised-but-not-built shape the
epic's own coverage discipline exists to catch.

The gate derives its load-bearing set from declared verbatim strategies rather
than a hand-maintained list, so it cannot go stale as upstream changes. It sweeps
budgets from 4x total down to a quarter of total and asserts at every step that
no load-bearing id appears in omitted or shrunk, that isolatePrefix is
byte-identical, and that hardFailed is surfaced rather than silently passed.

Both anti-vacuity guards are EXECUTABLE, not comments. One proves the empty
load-bearing set guard actually throws. The other proves a sweep that never
applies pressure is rejected — because a gate that only ever runs unpressured is
exactly how the original mitigation went missing without anyone noticing.
Measured: underPressure true at 6 of 7 budgets, false only at 4x total.

Three ADR records corrected in the same change, all doc-vs-reality drift:

  - Decision item 2 describes a composer that trims by priority to fit a measured
    per-runtime cap. composeWorkflow in fact passes MAX_SAFE_INTEGER with every
    fragment verbatim (both verified in source), so no trimming happens there;
    the emitted-byte cap is a separate measure-and-fail gate and Windsurf's limit
    a bespoke truncation. The wording described an option as shipped behavior.
  - flag:--converge never reached a terminal state. #2992 withheld six atoms;
    five were resolved explicitly. This one was resolved in code by reusing
    state:plan-strategy-converge but recorded nowhere — the same gap #2995 closed
    for flag:--verify-only, and I closed five of six.
  - The open-questions list enumerated three questions while two Resolved-by
    blocks resolved an unlisted Question 4. It is now listed.

* fix(#3065): make the gate assert over production, not a copy of it

The isolated review found a blocker, and it was fatal to the gate's purpose: it
hand-copied applyBudget's fragment array into the test, so flipping a strategy in
src/prompt-budget.cts — say roadmap from verbatim to drop — would leave the gate
computing from its own untouched copy and still passing. A guard built as an
instance of the very divergence class it exists to prevent
(DEFECT.GENERATIVE-FIX) is worse than no guard, because it reports green.

Fixed by eliminating the duplicate rather than adding a parity assertion, the
same resolution used for the FAMILIES table in #2996. applyBudget's inline
construction is extracted to an exported buildBudgetFragments(), which both
applyBudget and the gate now call; the 1024 plan floor is exported as
PLAN_FLOOR_CHARS instead of being re-declared in the test. The extraction is pure
— verified behavior-preserving at budget=2000: hardFailed false, omitted
['context'], projectMd shrunk, plan truncation ~27.8%, all headers present. There
is no longer a second copy to diverge from.

Also fixed a vacuous assertion the same review caught: isolatePrefix was pinned
across the sweep, but no production fragment sets isolate:true, so the value is
always '' and the check could never fail. The pinning assertion stays, with an
honest comment that nothing in production sets it today, and a second test now
constructs an isolate:true fragment set and proves the prefix is non-empty and
byte-identical across a roomy and a severely tight budget — which is what makes
the first assertion capable of detecting a real change.

9ac0dfad58 chore(#2929): generalize prompt-budget into the shared context-composer seam (#2958)
* test(#2929): capture prompt-budget parity corpus pre-refactor

Phase 2 of epic #1671 generalizes prompt-budget's trim ladder into a shared
context-composer seam. Its success condition is that review-prompt output does
not change, and the only authority on "did not change" is the behavior that
shipped before the refactor. Capture that behavior now, while it is still the
live implementation.

47 characterization cases, every `expected` value computed by executing the
current implementation rather than hand-authored — the independence
CONTRIBUTING.md "Fixture provenance (#2371)" asks for.

A corpus is only worth what it can detect, so this one was validated by
mutation rather than assumed. Five deliberate defects were injected and each
must be caught by at least one case:

  - the note reserve deducted unconditionally instead of only under pressure
  - the pressure test relaxed from `>` to `>=`
  - a no-op head-shrink still setting the shrunk flag
  - the per-plan floor dropped from the proportional share
  - drop order reversed

Two of those exposed real holes in the first cut of this corpus, and the cases
that close them exist because of it:

  - `>=` was caught by NOTHING. At exact cap the only trimmable fragment was a
    floored plan group, and the 1024-char floor absorbed the entire trim, so the
    mutation was byte-invisible. A3b/A3c put a droppable at exactly the cap,
    which makes the strict inequality observable as context kept vs omitted.

  - No case reached proportional-truncate at all — B6 and B7 both hard-failed
    the min-set pre-check first, leaving planTruncationPct at 0 across every
    case and the floor semantics entirely unexercised. Rebudgeted to 700 and
    1100 so the min-set fits and the truncate step is actually reached; they now
    record 40.20% and 48.80%.

The A4/A10 families sweep the pressure boundary from both sides, which is where
this function has regressed before: CONTEXT.md's
LEARNING.prompt-budget.boundary-gap records PR #3708 shipping two regressions
that only fired when the baseline sat inside the NOTE_RESERVE_TOKENS band,
because the suite paired a trivially-fitting budget with a trivially-overflowing
one and never sampled between them. A4 pins that nothing is trimmed from the cap
down to 81 tokens under it; A10 pins that pressure fires at +1. Together with
A3b/A3c they satisfy row (d) of RULESET.TESTS.boundary-coverage.fixtures.

Two facts the corpus establishes that the design notes had wrong:

  - "" and null sections are NOT distinguished. applyBudget uses truthy checks
    throughout, so an empty-string section is treated as absent: not rendered,
    not dropped, never recorded in `omitted`. B13b pins this while the ladder is
    actively trimming, where only the non-empty `research` is dropped.

  - Sizing matters. B12/B13 were first written at a budget where both hard-failed
    the min-set check and returned "", so comparing them compared two empty
    strings and proved nothing.

Committed as its own commit, ahead of the refactor, and regenerated against the
pre-refactor implementation, so the oracle is demonstrably independent of the
change it will adjudicate.

Refs #2929

* refactor(#2929): extract the context-composer seam from prompt-budget

Epic #1671 needs prompt-budget's budget-trimming logic for a second consumer —
per-runtime artifact emission — but it is walled inside the cross-AI review
pipeline. Lift it into a shared seam so later phases can call it, without
changing what the review pipeline emits.

ADR-1671 specifies the composer as "priority + binary-search cutoff to a
per-runtime budget". Read against the code it generalizes, that contract cannot
express the thing being generalized. applyBudget is not a cutoff: it is a fixed
five-step ladder in which each section carries its own shrink strategy, and only
three of its eight sections are ever dropped. PROJECT.md is head-shrunk to N
lines; plans are proportionally tail-truncated with a per-plan 1024-byte floor;
instructions and roadmap are never touched at all. A cutoff composer sorts by
priority and discards the tail — it has no way to say "shrink this one",
"truncate that one but never below 1 KB each", or "these three are the only
droppables, in this order". Building to the literal contract and routing
prompt-budget through it would have silently changed review-prompt output, which
is the one outcome this phase forbids.

So shrink strategies are the core abstraction here, and cutoff becomes one
strategy among them — the right one for per-runtime emission in Phases 3-4, not
for this ladder. That is an elaboration of the ADR's intent, not a departure
from it, and ADR-1671 is updated to say so.

Three decisions worth stating:

  - The composer DECIDES; the caller RENDERS. composeWithinBudget returns a plan
    of surviving fragments and never a string. assemblePrompt's rendering is
    prompt-shaped (`## Roadmap`, `### <file>`, the note in position two), and
    owning it in the composer would force emission to adopt prompt-shaped
    rendering. The split is what lets one seam serve both consumers.

  - The budget unit is INJECTED via `measure(text)`. prompt-budget passes its
    chars/4 estimator; emission will pass a byte counter, which ADR-1671 requires
    for emission caps. The existing code converts a token budget to a character
    budget with a hardcoded `* 4`; that assumption is now an explicit
    `charsPerUnit` inverse, which is precisely what a byte unit needs in order to
    reuse this.

  - The entry point is `composeWithinBudget`, not `applyBudget`. That name
    already exists twice — src/prompt-budget.cts and src/graphify.cts, the latter
    being an unrelated graph-edge budget. A third would make every symbol search
    in this repo ambiguous, and it already misresolves: preflight and impact
    queries for "applyBudget" return graphify's.

Behavior is unchanged and proven so: all 47 characterization cases reproduce
byte-identically, and the corpus is mutation-validated rather than merely green
(see the preceding commit). prompt-budget.cts drops from 436 to 343 lines and
from eighteen mutable accumulators to two, both inside a helper copied verbatim.

estimateTokens deliberately stays in prompt-budget and keeps its exact math:
src/phase-estimation.cts re-exports it as measureTokens, and CONTEXT.md pins
plan estimates and recorded actuals to that same scale, so moving or changing it
would silently break the calibration loop.

Refs #2929

* docs(#2929): document the context-composer seam and amend ADR-1671

Adds the INVENTORY row, the CONTEXT.md glossary entry (a PR gate for new
domain modules), and a mutation-matrix entry for the new module.

The ADR amendment is the substantive part. ADR-1671 specified the composer as
"priority + binary-search cutoff to a per-runtime budget". Implementing Phase 2
established that a cutoff alone cannot express the function the platform
generalizes, so the ADR now records shrink strategies as the core abstraction
with cutoff as one strategy among them, reserved for per-runtime emission in
Phases 3-4. Recording it in the ADR matters because Phases 3-6 are planned
against that contract and would otherwise be planned against a mechanism that
does not work.

The mutation-matrix entry is not bookkeeping. Stryker scores per module against
a named .cjs, so relocating the ladder out of prompt-budget.cjs would leave the
extracted code unmeasured while prompt-budget's own score floated free of the
logic it used to cover. context-composer gets its own entry at the same floor.

Refs #2929

* test(#2929): pin the effectiveBudget rounding mode in the parity corpus

An isolated correctness review found a real blind spot: mutating
`Math.floor` to `Math.round` in the effectiveBudget calculation failed ZERO of
the 47 corpus cases. Every (budget, safetyMarginPct) pair in the generator
happened to produce a whole number, so floor, round and ceil all agreed and the
rounding mode was entirely unpinned by a corpus whose whole job is to pin
observable behavior.

Three cases fix that by straddling the .5 boundary:

  A11  95 * 0.90  = 85.5   floor 85, round 86  -> the two disagree
  A12  97 * 0.90  = 87.3   floor and round agree; ceil (88) does not
  A13  93 * 0.85  = 79.05  same guard at a non-multiple-of-10 margin, so the
                           margin arithmetic is exercised and not just the budget

A11 alone catches the round mutation; all three catch ceil. Regenerated against
the pre-refactor implementation (`git show 9557f8552:src/prompt-budget.cts`), so
the expanded corpus keeps the independence property the original capture had.

The corpus is now mutation-validated against seven injected defects, every one
caught: unconditional note reserve, `>` relaxed to `>=`, no-op head-shrink
setting its flag, the truncate floor ignored, drop order reversed, and both
rounding-mode changes.

Refs #2929

* feat(#2929): flexReserve floors and the byte-stable isolate prefix

Two of issue #2929's "Done when" items were unimplemented rather than deferred,
and an isolated review flagged them alongside my own audit. Both are part of
ADR-1671's composer contract, so shipping the seam without them would have left
Phases 3-4 building against a contract that does not exist yet.

flexReserve is a per-fragment floor in measure units that every strategy must
respect, which is what makes it different from the pre-existing floorChars: that
one is a chars-denominated detail of proportional-truncate alone and is retained
unchanged. A floored fragment is never dropped, is never head-shrunk below its
floor, and raises its own proportional cap. A fragment already smaller than its
floor is untouchable outright. Metadata gains `floored`, listing the ids whose
floor actually prevented a trim — a guarantee no caller can observe is a
guarantee no test can hold you to.

isolate marks the byte-stable canonical prefix the ADR calls for: never trimmed,
never dropped, but still counted, because a prefix excluded from accounting
would silently under-count real context. Metadata gains `isolatePrefix` so a
caller can hash or assert on the exact bytes. Declaring an isolate fragment
after a non-isolate one throws: a prefix that is not at the front is not a
prefix, and accepting it would make the cross-runtime stability claim
meaningless.

Adds tests/context-composer.test.cjs for the exact new semantics and
tests/context-composer.property.test.cjs for the five invariants, including the
budget-monotonicity property the issue names explicitly. Both are registered in
the mutation matrix, since coverage does not migrate with relocated code.

prompt-budget uses neither feature, and its output is unchanged: all 50 corpus
cases still reproduce byte-identically.

Refs #2929

* chore(#2929): allowlist the prompt-budget parity suite

The parity corpus needs its own test file and that makes prompt-budget a
three-file module against a limit of two. The lint offers consolidation or an
allowlist entry with justification; the entry is the right call here.

Consolidation would mean folding the characterization suite into
prompt-budget.test.cjs, which is the one thing that should not happen to it. The
parity suite is a distinct concern with a distinct lifecycle: it is generated
rather than hand-written, it is named by scripts/mutation-matrix.cjs as its own
scoring target, and its failure means something categorically different from a
unit-test failure — not "this behavior is wrong" but "observable output moved".
Burying it inside a general unit file would obscure exactly that signal.

The allowlist is an identity ratchet, so this entry pins today's three exact
filenames: adding a fourth still fails, and dropping back to two requires
removing the entry.

Refs #2929

* fix(#2929): register the new module with two gates it was missing

The remote matrix caught three defects that no local check could, because the
local runner is blocked in this repo and these suites had therefore never
executed. Eight failures, identical on node22 and node24, so nothing
environment-shaped.

Two are the new-module ripple. A net-new src/*.cts lands in six places and this
change had reached four of them — .gitignore, INVENTORY, the manifest, and the
CONTEXT.md glossary — while missing the ESLint ignore list (tsc OUTPUTS must not
be linted; repo-invariants asserts linted-xor-ignored) and the mutation ratchet
baseline (a deliberate review-visible mirror of the matrix floors, which every
COVERED module must carry). Both are now registered, the ratchet at the same
floor of 66 the matrix declares.

The third was a test asserting an outcome it had made impossible. It set
budget:1 alongside a 400-char required fragment, so the group budget came out at
-99 and the proportional-truncate step was skipped entirely — the deliberate
"non-positive group budget is skipped, never clamped" rule inherited from the
original ladder. Nothing was trimmed, and the test then asserted a truncation.
Rebudgeted so the step actually runs, with the arithmetic written out in a
comment so the next reader does not have to re-derive why 120 rather than 80.

Fixing that surfaced a genuine bug in the composer. `floored` is documented as
recording fragments whose flexReserve prevented a trim that would otherwise have
happened, but the push sat in the else-branch of "content did not change", so it
only fired when nothing was trimmed at all. A fragment truncated to a
reserve-raised cap has also had a trim prevented — 40 characters' worth in the
test above — and was silently absent from the field that exists to make the
guarantee observable. The condition was already right; it was in the wrong
branch. Now recorded on both paths: a drop prevented outright, and a truncation
capped higher than the share alone would have allowed.

Parity is unaffected — prompt-budget never sets flexReserve, so the branch is
unreachable from every corpus path, and all 50 cases still match.

df04aae5e4 enhancement(#537): migrate all hand-written bin/lib/*.cjs to TypeScript source of truth (ADR-457) (#602)
* enhancement(#537): migrate code-review-flags to TS source of truth

Collapse the hand-written get-shit-done/bin/lib/code-review-flags.cjs to a
TypeScript source of truth (src/code-review-flags.cts), compiled by tsc to a
gitignored .cjs build artifact at the same path, per ADR-457 (build-at-publish).
Second module after the semver-compare pilot (#541).

Behaviour is preserved byte-for-behaviour (characterization test added in
tests/code-review-flags.test.cjs locks the parser quirks). Adds compile-time
type checking: CodeReviewFlags interface + CodeReviewWorkflow literal union.
The require() path is unchanged, so code-review.md and the bug-3727 test keep
working. The emitted .cjs is gitignored and eslint-ignored, mirroring the pilot.

config-types.cjs (has a src counterpart) and drop the redundant

(1615), init (2113). Adds src/package-identity.d.cts so verify can import the
permanently value-baked package-identity.cjs under strict TS.

Fixes two regressions the migration introduced in verify: restore
cmdValidateHealth's `return result` (callers/tests read result.warnings — it is
NOT side-effect-only), and make the bug-3384 source-pattern test tolerant of the
tsc-compiled bracket-notation form of the git_list_failed->W020 branch (behaviour
intact). Full suite green across all shards (only the 4 local gpg-env failures);
lint 0 errors. All 86 migratable bin/lib modules are now TypeScript sources.

* chore(#537): finalize ADR-457 migration — retire tsconfig.lint.json

All hand-written bin/lib/*.cjs are now src/*.cts sources, so the checkJs
stopgap tsconfig.lint.json (unused; not wired into eslint, scripts, or CI) is
deleted per ADR-457's final step. Also gitignore the tsc-generated
config-types.cjs (was still committed) for consistency with every other
emitted artifact. package-identity.cjs stays value-baked (declared via
src/package-identity.d.cts). Suite green; #551 ESLint-coverage test green.

* fix(#537): add prepare script so unpacked/git installs build bin/lib artifacts

ADR-457 build-at-publish: bin/lib/*.cjs are now gitignored, built by tsc. The
prepack/prepublishOnly hooks cover `npm pack`/publish, but `npm install -g
<dir>` and git installs run the `prepare` lifecycle — which was missing — so the
unpacked install shipped without the compiled .cjs and failed at startup with
"Cannot find module './lib/core.cjs'" (caught by the smoke-unpacked CI job).
Add `prepare` mirroring prepublishOnly (build:lib + build:hooks). prepare does
NOT run for registry consumers (they get the pre-built tarball), only for
source/local/pack installs.

* fix(#537): make CI build/lockfile checks work with gitignored bin/lib artifacts

ADR-457 build-at-publish exposed two CI assumptions that bin/lib/*.cjs are
always present on disk:
- check:env's lockfile-sync ran `npm ci --dry-run`, which now triggers the
  `prepare` build (tsc) — but it runs before deps are installed, so tsc is
  absent and it misreported the lockfile as out of sync. Add --ignore-scripts
  (a lockfile check must not build).
- the lint-tests job installs with --ignore-scripts (no prepare build), but
  lint:skill-deps require()s the built install-profiles.cjs. Add an explicit
  `npm run build:lib` step after install.

* fix(#537): narrow prepare to build:lib only (unbreak packed-smoke pack step)

prepare running build:hooks emitted "✓ Copying ..." stdout during `npm pack`,
which the install-smoke "Pack root tarball" step captures into $GITHUB_OUTPUT —
breaking it with "Invalid format". build:lib (tsc) is silent on success and is
all the unpacked/source install needs (the smoke-unpacked assertions exercise
gsd-tools, i.e. bin/lib, and tolerate hook setup with `|| true`). Matches
prepack. build:hooks still runs on prepublishOnly for real publishes.

* fix(#537): wire Stryker mutation gate to build-at-publish layout

The gate scored 0.00 because it mutated changed bin/lib/*.cjs that (a) were
generated artifacts and (b) included modules with no coverage in the command's
test set. Rework: mutation.yml now derives changed COVERED modules from
src/*.cts and maps them to their built bin/lib/*.cjs; Stryker mutates those
built artifacts with a no-rebuild command (mutating src/*.cts + per-mutant tsc
was ~3x over the 30-min CI budget).

NOTE: with the gate now correctly measuring the covered modules, their actual
mutation score is 42.94% (< break 50) — a pre-existing test-coverage gap
(adr-parser/prompt-budget/etc.), not introduced by this behaviour-preserving
migration. Reaching 50 needs more tests, a threshold/scope change, or a waiver —
a maintainer decision.

* test(#537): raise mutation coverage of covered modules above the 50 gate

Adds focused example-based unit tests that kill surviving mutants in the two
lowest-scoring covered modules:
- tests/prompt-budget.unit.test.cjs (112 tests): 17.9% -> 97.9%
- tests/adr-parser.unit.test.cjs (205 tests): 44.7% -> 89.4%
Both wired into stryker.config.mjs's command. Fresh full run over the 6 covered
modules now scores 82.25% (>= break 50); every covered module is >= 68%.

* enhancement(#537,#609): parallelize mutation gate via dynamic per-module matrix

The serial Stryker run timed out at 30 min once the migration's added tests
made every mutant re-run ~300 tests. Replace it with a dynamic matrix so the
gate completes well under budget — folded into this PR (was tracked as #609)
because it's a prerequisite for this PR's mutation gate to pass.

- scripts/mutation-matrix.cjs: single source of truth (covered-module -> test
  files) computing changed covered modules from git diff -> {has_work, matrix}.
- mutation.yml: detect -> dynamic `matrix: fromJSON(...)` mutate job (one
  parallel shard per changed module, scoped via MUTATION_TEST_CMD to only that
  module's tests, 15-min/shard) -> summary job that KEEPS the legacy check name
  "Stryker mutation score (changed files only)" so branch protection is
  unchanged. Per-shard jobs report as "Stryker (<module>)".
- stryker.config.mjs: commandRunner.command reads MUTATION_TEST_CMD (falls back
  to the full command locally).

Closes #609.

* test(#537,#609): give each mutation shard ≥50% on its own tests; drop blacksmith note

Per-module sharding revealed that active-workstream-store (46.5%) and
frontmatter (7.4%) only cleared 50% in the old serial run via timeout-noise from
the bloated 300-test command; on their own tests they were below the gate. Add
focused unit tests:
- tests/active-workstream-store.unit.test.cjs (115 tests): 46.5% -> 81.9%
- tests/frontmatter.unit.test.cjs (165 tests): 7.4% -> 63.4%
Both wired into scripts/mutation-matrix.cjs (per-module test map) and
stryker.config.mjs DEFAULT_TEST_CMD. All 6 covered modules now clear break:50
with only their own tests (config-schema/context-utilization/prompt-budget/
adr-parser already did). Also removes the leftover blacksmith TODO comment —
GitHub-hosted runners only; speed comes from parallel per-module shards.

* test(#537,#609): strengthen prompt-budget tests to clear the gate on its own tests

prompt-budget scored 39.58% when mutation-tested with ONLY its own tests (the
way the per-module CI shard runs it) — an earlier ~98% reading was inflated by
accidentally running the full multi-module command. Add 96 targeted tests to
tests/prompt-budget.unit.test.cjs (exact note-template text, plan-truncation
arithmetic/percentages, drop-block strings, noteInjected/hardFailed booleans):
scoped score 39.58% -> 68.75% (>= break 50). All 6 covered modules now clear
the gate on their own tests.
