Tom Boucher e6d047decc fix(#4129): derive completed_phases from the ROADMAP authority; honor the progress-ratchet on every state write (#4359)
* test(#4129): failing-first regressions — completed_phases clobber on resyncing writes and phase-complete failure to increment

* fix(#4129): completed_phases derives from the ROADMAP authority and the write path honors the progress-ratchet

Three coordinated prongs (diagnosis in .gsd/bug/fix-4129-completed-phases-recompute/):

P1 — buildStateFrontmatter's disk scan floors the completed-phases numerator at
the milestone-scoped ROADMAP Complete-row count (deriveProgressFromRoadmap, the
one owner), gated inside the same safeToUseRoadmapCount / not-withheld branch
that owns the denominator. A completed phase whose verification routes stale
(#2348 clean-commit-time drift) or is missing no longer under-counts forever.

P2 — applyPreserveAlways's resync arm merges instead of wholesale-replacing on
a measured scan: totals derived both directions (#2440), completed counters
up-only (#2969 — the schema-declared progress-ratchet, now enforced on the
write path like the read path always has), percent recomputed from the merged
counters. The #3756 unmeasured guard and the #3242 explicit-progress contract
are unchanged.

P3 — phase complete's atomic 3-file commit passes the post-completion
ROADMAP-derived counters through the #2736 authoritativeFm seam (new object
direction for the progress key; completedOnlyRaise at the post-preservation
re-assert), because the transaction's disk scan reads the pre-completion
ROADMAP and failed to increment on the completing phase's own write.

* fix(#4129): adversarial-review hardening — intent is a floor at BOTH authoritativeFm sites

The pre-preservation merge could lower a correctly-higher disk-derived
counter (a verification-passed phase whose ROADMAP table row drifted behind
the disk signal). completedOnlyRaise now governs both application sites: the
intent and the derivation agree on direction (up), never on subtraction.

* fix(#4129): the ratchet merge keeps derived values verbatim when numerically equal

The re-parsed derived block carries string scalars ("2") while the curated
snapshot carries numbers (2); substituting the curated spelling over an
equal derived one was a no-op in substance but a shape churn the ADR-3473
§8.7 reporting loop surfaced as a phantom preserved-over-disagreeing-derived
warning on phase complete (ADR-3408 §8.5 Matrix B). Only a strictly-greater
curated counter replaces the derived value now; percent gets the same
verbatim rule.

* changeset(#4129): backfill PR 4359

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.
