* enhance(#4404): add offline token benchmark for compact-content splits ADR-4139 Decision 2 requires the finite-attention justification for workflow.compact_content to be measured, not asserted. `npm run benchmark:compact-content` computes, per registered spine/detail split discovered under gsd-core/workflows/, the token count with the split active (spine alone) vs inactive (spine + all detail parts read back in), using gpt-tokenizer (pinned exact devDependency — Anthropic publishes no tokenizer for Claude 3+, so every output surface labels this a PROXY-TOKENIZER comparison: the on/off delta is exact under one tokenizer applied identically to both sides, the absolute counts are not Claude's real ones). Reporting-only by design and verified so: --check diffs the live recompute against a committed baseline (tests/fixtures/compact-content-benchmark-baseline.json) and prints drift, but never exits non-zero for a drifted or missing baseline — the only thing allowed to fail this script is a genuine I/O error reading a source .md file it's measuring. Not wired into lint:ci or pretest. Discovery is deliberately reimplemented rather than importing tests/helpers/compact-content-split.cjs (Phase 3, #4403), keeping a scripts/ reporting tool from depending on a test-only module. tests/fixtures/deny-network.cjs preloads via NODE_OPTIONS=--require to prove the benchmark makes no network call, monkeypatching http/https/ net/dns/fetch to throw rather than relying on sandboxing. docs/CONFIGURATION.md documents the new benchmark against the workflow.compact_content key to satisfy this repo's docs-required gate for an Added-type changeset. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(#4404): address orthogonal review findings on the token benchmark Standards axis found two hard violations against documented rules: - CLAUDE.md's Generative Fix Divergence rule requires a parity assertion for shared discovery logic maintained in two places. Added a test comparing benchmark-compact-content.cjs's own discoverRegisteredSplits against tests/helpers/compact-content-split.cjs's version on the real repo tree, so the two can never silently drift apart. - The changeset body closed its bold span with a period and continued as a second sentence, instead of the canonical `**<phrase>** — <explanation>.` shape CONTRIBUTING.md documents. Spec axis found the "network disabled + identical output across two runs" Done-when criterion was verified as two separate properties (determinism tested without network denial, offline survival tested as a single run) rather than as one combined property. Added a test that runs the benchmark twice under the deny-network preload and asserts byte-identical stdout. Security axis found tests/fixtures/deny-network.cjs didn't patch dns.promises (a separate binding from the callback dns API), tls.connect, or http2.connect — inert today since nothing in the benchmark calls them, but a silent gap in what the preload's own header claims to guarantee. Patched all three. CLAUDE.md's Property-Based Testing rule also requires a fast-check test for budget-limit arithmetic; added one for computeAggregate's off/on summation (true sum over N splits, never NaN/Infinity, never exceeds 100% when off >= on for every split). Standards axis's remaining two findings (a Data Clumps observation on the {offTokens, onTokens, reductionPct} triple, and mild duplication in formatDriftReport's three line-formatters) are left as judgement calls: introducing a named type for a 3-field local tuple, or a formatter abstraction for three short lines, would be exactly the premature abstraction CLAUDE.md's engineering guidance warns against for a script this size. All changes verified directly (parity logic, the fast-check property, and the three newly-denied network surfaces actually throwing under the preload) via node -e before committing; full npm run lint:ci passes with the eslint cache cleared.

Changeset Fragments
This directory holds per-PR CHANGELOG fragments. Every PR with user-facing changes drops one (or more) <random-name>.md files here describing its CHANGELOG entry. Fragments are consolidated into the top-level CHANGELOG.md at release time.
Why
Two PRs that both edit the ### Fixed block of CHANGELOG.md always conflict on merge — git can't pick a serialization order without human input. Two PRs that each add a fresh .changeset/<unique-name>.md never conflict because they don't share lines.
See #2975 for the full rationale.
Adding a fragment
node scripts/changeset/new.cjs \
--type Fixed \
--pr 1234 \
--body "fix the thing — explain the user-visible change in one sentence"
This writes .changeset/<adjective>-<noun>-<noun>.md with frontmatter and a body. Three random words → concurrent PRs don't collide.
Format
---
type: Fixed
pr: 1234
---
**`/gsd-foo` no longer drops trailing slashes** — explain the user-visible change.
Allowed type: values follow Keep a Changelog: Added, Changed, Deprecated, Removed, Fixed, Security.
Opting out
PRs that legitimately have no user-facing impact can add the no-changelog label. CI honors it. When unsure, add the fragment.
At release time
Promotion is automatic. The release workflow's finalize job runs:
node scripts/changeset/cli.cjs render --version vX.Y.Z --date YYYY-MM-DD --allow-empty
This reads every fragment, groups bullets by type:, replaces ## [Unreleased] with a new ## [vX.Y.Z] - YYYY-MM-DD block, opens a fresh ## [Unreleased] above, and deletes consumed fragments. The --allow-empty flag ensures a no-change release still gets a dated heading (with a _No notable changes._ placeholder). A subsequent verify step confirms the promotion landed correctly. Maintainers do not run this by hand.
Archived fragments
.changeset/archived/ holds fragments for already-shipped releases (≤ 1.3.1), retained for provenance. Their content was hand-curated into the dated ## [1.x.y] sections of CHANGELOG.md during the #690 backfill — they were never consumed by render. All changeset tooling enumerates .changeset/ non-recursively, so archived fragments are never picked up or rendered. Do not move them back to the top level.
