Root cause of the 501-commit pile-up in inter-hub: fix_repo() created
git commits (brief updates, T03 writebacks) but never pushed them, so
the 15-minute timer accumulated local commits indefinitely. Once real
development landed on remote the repos diverged with no self-healing path.
Changes
-------
repo_sync.py (new module)
Extracts all git lifecycle primitives: pull_ff, push_ff,
count_remote_ahead (C-16 input), count_local_ahead (C-17/T04 input).
Module docstring documents the push-seal invariant and stable state.
consistency_check.py
- Imports primitives from repo_sync; thin _detect_behind_remote wrapper
preserves backward compat for existing callers and tests.
- C-17 backlog guard: if local has unpushed commits from a prior failed
push, retry before making more; skip all writes if push still fails.
- T04 push seal: unconditional push_ff() at end of every fix_repo() run.
- _report_needs_action: ahead_of_remote param so repos with unpushed
backlogs are not silently skipped as "clean" by fix_all_remote().
- Domain-slug fallback: brief no longer degrades to "(unknown)" when all
workplans are completed — falls back to any workstream for domain context.
- Service switched from --all --fix to --remote --all (pulls before
fixing, skips already-clean repos).
push-seal.md (new)
Capability documentation: the problem, the invariant, all three checks
(C-16/C-17/T04), stable-state description, API reference, and test map.
test_repo_sync.py (new, 32 tests)
Full coverage of all four primitives via real git repos (tmp_path).
Includes C-17 scenario, push-seal invariant, and four end-to-end
loop-stability tests.
test_consistency_check.py
Four new _report_needs_action cases for the ahead_of_remote parameter.
