T01 — No-regress rule (C-15): fix-consistency now detects when a DB task
status is ahead of the workplan file (e.g. marked done on CoulombCore)
and emits C-15 WARN instead of regressing the DB back to the stale file
value. STATUS_ORDER ranking: todo(0) < in_progress/blocked(1) < done/cancelled(2).
T02 — Pull gate (C-16): fix_repo runs git fetch + rev-parse at the start
of every --fix run. If the local repo is behind its remote tracking branch,
all write operations are skipped and C-16 WARN is emitted. Best-effort:
offline/no-remote silently skips the check.
T03 — DB→file writeback: C-15 fix path patches the status field in the
matching task block and git-commits the change with a standard message.
--no-writeback flag disables writeback while keeping T01/T02 active.
T04 — CLAUDE.md + session-protocol.template updated with new guidance,
C-15/C-16 semantics, and fix-consistency-remote recommendation.
T05 — Makefile: fix-consistency-remote pulls then fixes in one step.
16 new tests; 155 passed total.
