The convergence lint only scanned src/ + gsd-core/bin, so ~35 test files
still imported core.cjs. Repoint all 33 behaviour importers to the leaf
modules directly (same symbol->leaf map as the src migration; leaves are the
objects core re-exported by reference), delete the now-meaningless
shim-identity describe blocks in the 8 leaf tests, and delete tests/core.test.cjs
(forwarded-behaviour coverage now lives at the leaves; resolveWorktreeRoot
test relocated to worktree-safety in T0) and tests/lint-core-spine-imports.test.cjs
(the lint is removed in T-final). Dropped the stale core.test.cjs entries from
the allow-test-rule-refs allowlist; eslint-rules RuleTester fixture path
pointed at io.cjs.
After T6: ZERO test imports core.cjs. core.cts still builds (now fully unused);
T-final deletes it. No behaviour change.

ADR-857 rollout phase 2a — the first cut of the core.cts decomposition.
Move the 9 pure phase-id parsing/matching helpers (escapeRegex,
normalizePhaseName, comparePhaseNum, extractPhaseToken, phaseTokenMatches,
phaseMarkdownRegexSource/Exact, getMilestoneFromPhaseId, getPhaseDirFromPhaseId)
out of core.cts into a new leaf module src/phase-id.cts. core.cts re-exports
them (behavior-preserving); its internal callers resolve the destructured
bindings.
Cycle-safe by design: phase-id depends on nothing in core, so re-export creates
no circular require (the property that made phase-1 io.cts clean). This is the
leaf-first ordering — it unblocks the roadmap-parser extraction (2b), which
imports phaseMarkdownRegexSource.
New-CLI-module checklist: .gitignore, eslint.config.mjs ignores, INVENTORY.md
count 91->92 + row, INVENTORY-MANIFEST.json, ARCHITECTURE.md row, CONTEXT.md
"Phase Id Module" glossary entry. Adds tests/phase-id.test.cjs (63 behavioral
tests incl. shim-identity + adversarial inputs).
Gates: lint, code-review, security-review, codex adversarial-review (all 0
findings), and gsd-test-both (14814 pass on Mac + Linux Docker, 0 fail).
Closes#865
