After adr-2609212115255771 retired the phase, the milestone and the word roadmap, the brief outside the mental-model chapter still describes the phase as the live sequencing unit: 59 files under .abcd/development/brief mention it, among them 01-product/04-scope.md (bounded by the planned phases), and the glossary entries release, version, loop, plan and spec, whose prose says a phase sequences the work and a release falls out of completing one. itd-2609211913453478 rewrote only the mental-model chapter and repointed each entry's not_to_be_confused_with; no record carries the rest of the sweep.

Sweep progress 2026-09-29

Lane drainBrief (autonomous run A, c80832f97) swept the brief outside the files other branches were editing. Done: 01-product/04-scope.md (the scope is the shelves, sequenced by dependencies and rendered as the Now / Next / Later block), the glossary entries release, version, loop, plan and spec, and the phase-as-sequencing sites in 01-product/ (press release, context, README), 02-constraints/01-platform.md and 02-dependencies.md, 03-evidence/04-tradeoffs.md, 04-surfaces/02-disembark.md, 03-embark.md and 07-memory.md, 05-internals/ 01, 04, 05, 07, 08 and 09, 06-delivery/README.md and the opening of 01-build-sequence.md, and the glossary's core README, brief, reading-position and ledger/position entries and the distribution README.

Left, and why:

• Files other branches were editing, which this lane was barred from: 02-constraints/04-naming.md (15 sites), 02-constraints/03-invariants.md (1), 05-internals/03-configuration.md (7), 06-delivery/02-verification-matrix.md (2), 06-delivery/03-out-of-scope.md (22), 04-surfaces/01-ahoy.md (1), 04-surfaces/04-launch.md (4), 04-surfaces/05-intent.md (36) and 04-surfaces/README.md (1).
• 04-surfaces/09-reflect.md: its whole design is phase-grained (argument, seed, output path). The chapter now says the grain is retired and that the release-grain design is owed with itd-24; restating it is a design act for that intent, not a sweep. The reflection-composer row of 05-internals/01-agents.md (from a phase-audit receipt) goes with it.
• 06-delivery/01-build-sequence.md: its build milestones are the brief's plumbing sequence for the Go core, a sense the phase glossary entry keeps apart and the ADR does not name. Only its opening pointer at the phase documents is swept.

Kept on purpose, as history or as another sense of the word: the retired entries glossary/core/phase.md, milestone.md and roadmap.md; introduced_in: phase-N provenance; links to the phase documents as history (glossary/core/loop.md, glossary/core/ledger.md); 00-meta.md:77, whose source list mirrors internal/core/lifeboat/mapping.go:206; the process phases of 04-surfaces/15-prepare-this-repo.md and the grill session's phases under glossary/interview/; and the voyage entry's lifecycle table.
