The migrated checkW027 (stale worktree) dropped the pre-migration
exclusion of the CLI's own current worktree, since a Rule.check(snapshot)
has no cwd access (§8.1 rule 1 forbids ambient I/O) — flagged as a
disclosed regression during this phase's own design work, then
confirmed as a real, fixable gap by the Spec-axis orthogonal review
rather than an inherent limitation.
Fixes it properly instead of accepting the regression: buildPlanningSnapshot(cwd)
already receives cwd as its own input, so exposing it as snapshot.cwd
is not new ambient I/O, just surfacing an existing parameter — fully
consistent with §8.1 rule 2's "parsed value" allowance. checkW027 now
excludes the entry matching snapshot.cwd before flagging, matching the
original verify.cts:2233-2242 behavior exactly.
W020 (3 conditions), W017, W027 — git worktree list degradation,
orphan and stale worktree checks, migrated onto the frozen rule table
per ADR-3180 §8.2. W027 has a documented fidelity reduction: rules
have no cwd access, so it can no longer exclude the active worktree.
W024 (deliberately inert, no snapshot field yet for stale state_head),
W002, W011, W021, W026 — STATE.md cross-checks against ROADMAP/config,
migrated onto the frozen rule table per ADR-3180 §8.2.
E002, E003, E004, W001 — PROJECT.md/ROADMAP.md/STATE.md existence and
PROJECT.md section-completeness checks, migrated onto the frozen rule
table per ADR-3180 §8.2.
