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 2c. Move 11 shared low-level utilities out of core.cts
into a new leaf module src/core-utils.cts: POSIX path normalization (toPosixPath),
filesystem scanning (detectSubRepos, readSubdirectories, getPhaseFileStats,
pathExistsInternal), and small pure helpers (generateSlugInternal,
extractOneLinerFromBody, filterPlanFiles, filterSummaryFiles, timeAgo, and the
private extractCanonicalPlanId). core.cts re-exports the 10 public ones
(callers unchanged); extractCanonicalPlanId stays private (exported from the
leaf for core's fs-search functions).
Cycle-free: core-utils depends only on Node built-ins + already-leafed modules
(phase-id for comparePhaseNum, planning-workspace for findContextMdIn). This is
the shared leaf that unblocks the phase-locator fs-search extraction (2d) —
searchPhaseInDir/findPhaseInternal/getArchivedPhaseDirs can now take their
utilities from a leaf instead of from core.
New-CLI-module checklist done (.gitignore, eslint, INVENTORY 93->94 + row,
manifest, ARCHITECTURE, CONTEXT.md "Core Utilities Module"). Adds
tests/core-utils.test.cjs (88 tests: behavioral + shim-identity + adversarial).
Gates: lint, code-review, security-review, codex adversarial-review (0
findings). Mac 4041 pass; clean-build docker 12935 pass, 0 fail.
