628648d63a chore(#2931): cap emitted per-runtime bytes and single-source windsurf (#2984)
* fix(#2931): preserve protected regions and cap emitted per-runtime bytes

Route every runtime brand swap through applyClaudeCodeBrandSwap so
"Claude Code" survives verbatim inside <runtime_compatibility> regions
(#2284b). The fix existed only in bin/install.js's local copies; the
src/*.cts exports still used a naive replace, so binding install.js to
the single source -- as this phase does for the Windsurf family --
would have silently regressed those runtimes. A table-driven parity
guard now covers all nine brand-swapping converters.

De-duplicate the Windsurf converter family: delete the six local copies
in bin/install.js and bind the four exported ones by reference, guarded
by reference-identity assertions (the ADR-1508/#1675 pattern). The two
unexported helpers and an unused tool table go with them.

Replace the Windsurf 12,000-byte throw with description truncation,
matching the bound its sibling skill converter already applied. The
throw could only fire on an ~11.7 KB frontmatter description: the
largest emitted workflow is 311 bytes. Truncation makes the cap
unreachable by construction and leaves 12,000 in exactly one place,
eliminating the dual-surface duplication rather than testing for it.

Add the emitted-byte cap gate: buildEmittedSizes captures LF- and
<HOME>-normalized bytes from the walk buildParityManifest already
performs, and evaluateEmittedCaps asserts them against a per-runtime
cap table with dead-rule detection. buildParityManifest's return shape
is deliberately unchanged -- diffEmitted compares its values with
===, so making them objects would report all 8,529 emitted paths as
moved. A regression test pins the values as strings.

Add a deterministic trim-safety gate over composeWithinBudget's
omitted/shrunk/floored/isolatePrefix metadata, with an anti-vacuity
rule, replacing the model-graded eval gate the issue described.

* docs(#2931): correct ADR-1671 windsurf premise and trim-safety contract

* fix(#2931): bound the windsurf command name and single-source the brand swap

Review findings from the orthogonal passes, all fixed inline.

The claim that removing the 12,000-byte throw left total emission
"bounded by construction" was false. The #1615 regex constrains the
character class but not the length, and commandName is interpolated
three times into the emitted workflow: a 20,000-character name emitted
60,162 bytes silently. Add WINDSURF_COMMAND_NAME_MAX=128 as a separate,
clearly-labelled size control that THROWS -- commandName is the @-ref
path target, so truncating it would point the workflow at a file that
does not exist (DEFECT.WORKFLOW-DELEGATION-TARGET-NOT-INSTALLED). The
#1615 security regex is untouched and still runs first. 128 is generous:
the longest shipped name is gsd-plan-review-convergence at 27.

Harmonize convertClaudeCommandToWindsurfSkill onto the code-point-safe
truncation helper. It still used a UTF-16 slice(0,177) -- the exact
surrogate-splitting bug the helper was written to avoid, in the very
sibling the helper's comment cites as its model. Bounds are unchanged,
so output is byte-identical for every shipped command (descriptions max
out at 99 chars).

Export applyClaudeCodeBrandSwap and bind it in bin/install.js, deleting
the local copy. Adding it to the .cts left two unlinked implementations
of identical logic -- the drift class this change exists to remove.
Verified byte-identical across eight fixtures and five sequential calls
before merging, and guarded by a reference-identity assertion.

Convert three try/finally test bodies to t.after (CONTRIBUTING.md:344),
add fast-check property coverage for the trim-safety contract, and use
fc.pre instead of a bare return in a property callback.

* test(#2931): fix three test-authoring bugs the remote matrix caught

The remote runner returned 8 unique failures on 6f15cdeb8. All three
causes were in the test files, not the modules under test -- local
harnesses exercise the modules directly, so nothing executed the test
bodies until the matrix did.

`{ __proto__: [...] }` in an object literal sets the prototype instead
of an own key, so the JSON round-trip erased it and the cap table never
saw a reserved runtime key. The production rejection was already
correct; the test could not reach it. Use a computed key.

Two cap fixtures tripped orthogonal error paths rather than the paths
they name: one declared windsurf in the cap table but omitted it from
sizes (UNKNOWN_RUNTIME), the other left the sole windsurf pattern
matching nothing (a genuine dead rule). Both now include a compliant
artifact so the intended branch is what is asserted. The dead-rule and
unknown-runtime contracts are deliberate and unchanged.

`const { root } = makeSyntheticConfig({ ... `${root}` })` referenced
`root` from inside its own initializer -- a temporal dead zone error.
makeSyntheticConfig now optionally takes a (root) => files factory.

Also raise the npm pack --dry-run bound 60s -> 120s in the shipped-
scripts packaging test. That failure is NOT from this branch: the file
is byte-identical to next, a fresh tsc measures 1.98s there vs 2.14s
here, and the run recorded 60,637ms against a 60,000ms bound -- a
timeout under 28,948-test parallel contention, not a slowdown. Fixed
rather than deferred because a bound that tight is fragile regardless
of which branch trips it.

d3305fc3a5 fix(#2858): exclude gen-emitted-baseline.cjs from npm tarball + class-extinction guard (#2968)
* test(#2858): add class-extinction guard for shipped-script require boundary

Every shipped scripts/**/*.cjs must be require-able using only shipped paths.
The guard resolves the tarball file list via npm pack --dry-run --json (not a
hardcoded list) and statically checks each require() call against the shipped
set. A script requiring ../tests/** (which does not ship) is a violation.

* fix(#2858): exclude gen-emitted-baseline.cjs from the npm tarball

scripts/gen-emitted-baseline.cjs is repo-only CI tooling (CI workflows +
test fixtures spawn it from a checkout). It requires three modules from
tests/, which does not ship — so in a published install it is
MODULE_NOT_FOUND at load time.

Add a targeted files[] negation (!scripts/gen-emitted-baseline.cjs) so the
script stays in the repo for CI use but does not ship. Other scripts that
ship and are required by bin/install.js (build-hooks.js,
fix-slash-commands.cjs, gen-capability-registry.cjs) are unaffected.

The class-extinction guard test in
tests/packaging-shipped-scripts-require-only-shipped.test.cjs ensures no
shipped script can require outside the shipped tree going forward.

* test(#2858): widen guard to .js + strip block comments (review fixes)

Two findings from isolated adversarial review:
1. MAJOR: the guard only checked .cjs files, but scripts/build-hooks.js
   ships and is required by bin/install.js — a .js file with a broken
   require would bypass the guard. Widened filter to /\.(cjs|js)$/.
2. MODERATE: the static parser could false-positive on require() calls
   inside /* */ block comments or inline // comments. Now strips both
   before matching.

* chore(#2858): add changeset fragment

* chore(#2858): backfill changeset PR number 2968

* fix(#2858): add issue ref to allow-test-rule exemption (ADR-456)

CI lint-tests caught: the allow-test-rule comment needs a 'see #NNN' ref
per ADR-456. Added '(see #2858)' to the integration-test-input exemption.
