* 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. * chore(#2931): backfill changeset pr number to 2984 --------- Co-authored-by: sim <sim@local>

* ── Scope note (A15) ────────────────────────────────────────────────────────
|
||||
* `.gsd/phase/chore-2931-emitted-byte-caps/40-design.md` "Scope resolution
|
||||
* (A15, made concrete during implementation)": `capabilities/windsurf/
|
||||
* capability.json` declares `commands -> destSubpath "workflows"` ONLY under
|
||||
* `artifactLayout.local`. The committed GLOBAL fixture
|
||||
* (tests/fixtures/install-tree/windsurf.json) holds 344 paths and has ZERO
|
||||
* `workflows/` entries — a global install cannot exercise the windsurf cap
|
||||
* rule at all. This file therefore builds a LOCAL windsurf install
|
||||
* (`runMinimalInstall({ runtime: 'windsurf', scope: 'local' })`), the only
|
||||

/**
|
||||
* emitted-caps.cjs — the per-runtime emitted-byte cap decision (issue #2931,
|
||||
* epic #1671, Phase 4). Sibling law to `emitted-diff.cjs`'s conservation law:
|
||||
* same pure/IO split, same error-accumulation shape, same reserved-key guard.
|
||||
*
|
||||
* ── Why this module is pure ──────────────────────────────────────────────────
|
||||
* No fs, no git, no clock, no process. The expensive part — spawning an
|
||||
* install and measuring real emitted bytes — lives elsewhere; this module only
|
||||
* decides, given a `{ [runtime]: { [rel]: bytes } }` map and a cap table,
|
||||
* which artifacts violate, which are unmeasured, and which comply. Keeping the
|
||||
* decision pure makes every boundary (`cap-1`/`cap`/`cap+1`) a millisecond
|
||||
* table test and keeps the Stryker gate able to bite.
|
||||
*
|
||||
* ── Why the cap table is HARD-CODED here, not read from capability.json ─────
|
||||
* ADR-2719's guiding principle (already load-bearing in `emitted-diff.cjs`:
|
||||
* it never re-derives a byte, because asserting `emitted == transform(source)`
|
||||
* is the tautology ADR-2264's Amendment rejected) applies here too, one level
|
||||
* up: a cap that is DERIVED from the same descriptor it is meant to guard
|
||||
* (`capabilities/<rt>/capability.json`) would silently follow any edit to that
|
||||
* descriptor. Bump the descriptor, the guard bumps with it, and a real
|
||||
* regression sails through unnoticed. `EMITTED_CAPS` is a second, independent
|
||||
* source of truth, edited deliberately by a human who has to look Windsurf's
|
||||
* actual 12,000-byte platform limit in the eye — exactly the friction a guard
|
||||
* exists to provide.

* guard for the #2284(b) protected-region fix.
|

*
|
||||
* `applyClaudeCodeBrandSwap` (src/runtime-artifact-conversion.cts) rewrites
|
||||
* bare "Claude Code" self-references to a runtime's brand name EXCEPT inside
|
||||
* `<runtime_compatibility>...</runtime_compatibility>` blocks, which must
|
||||
* survive byte-for-byte verbatim (a runtime-comparison table that says
|
||||
* "Claude Code" is describing Claude Code's own behavior, not this
|
||||
* runtime's — brand-swapping it mislabels the comparison). The Windsurf
|
||||
* converter got this fix; every sibling markdown/agent converter that also
|
||||
* performs a "Claude Code" -> brand swap needed the SAME fix (#2284b
|

* follow-up).
|

*
|

* A per-converter regression test would only catch a REintroduction in the
|

* converter it targets — the exact shape of divergence CONTEXT.md's
|

* DEFECT.GENERATIVE-FIX names. This file instead drives every brand-swapping
|

* converter through ONE assertion body from a declarative table, so a NEW
|

* runtime converter that skips `applyClaudeCodeBrandSwap` and reintroduces a
