feat(go): build-mode batch 1 — the phase machine + ledger mechanics (contract BUILDER-2026-10-07T17:08:00Z-6e177d-unknown)
Deterministic core of build_mode.py ported to src/go/build-mode:
- the 11-phase machine in declaration order + PhaseStatus/BuildPhase/
  VerificationTier constants
- LogPhase + the named completion functions, clock INJECTED
  (date-time-bomb law); side effects pinned: complete_plan assigns
  batches, start_correct increments corrections
- ResumePoint (reversed declaration-order scan) + the pinned quirk:
  complete_verify(false) records status 'complete' with the failure in
  DETAILS — the resume scan never fires on it
- BuildStatus shape; build_id %Y%m%d-%H%M%S from the injected clock
- module-family CLI (curator-core convention); worktree git ops stay
  reactive (batch 2)

PARITY: truth_buildmode.json — 5 flow cases with RECORDED CALLS replayed
through the ported functions; the oracle's ledger pinned two subtleties my
first read missed (complete_feasible's nested details key; assess/research
log their parameter dicts, not kwargs maps). Comparisons are canonical-JSON
(Go []string vs decoded []interface{} differ in type, not bytes).

"""gen_build_mode_truth.py — build-mode batch 1 truth battery
(contract BUILDER-2026-10-07T17:08:00Z-6e177d-unknown).
The LIVE BuildManager runs with the clock FROZEN (module-patched datetime)
and create_worktree no-op'd (reactive piece, deferred to batch 2). Cases
capture: the start_build id format, the ledger flow across phases
(including a failure + correction), resume-point scans at several states,
and the status shape. The Go replay compares state dicts key-for-key.
Usage: python3 scripts/gen_build_mode_truth.py (from repo root)
