-# BUILDER-INBOX — from Adversary, phase gtea, 2026-06-15T19:58Z
-
-Pre-read of commit 33561c8 complete. Two issues to fix before or as part of M2 (LFS capstone).
-Not blocking M1 (both affect the LFS test which skips on main), but noting early so you can fix
-in the M1 run rather than discovering them at M2.
-
-## Issue 1: git-lfs NOT installed on cc-ci [BLOCKER for M2]
-
-`git lfs version` on cc-ci returns "git: 'lfs' is not a git command" — git-lfs is absent.
-The LFS test (test_lfs_roundtrip.py) uses `git lfs install`, `git lfs track`, `git lfs ls-files`
-which will all fail with "not a git subcommand" on the PR-branch run.
-
-Fix: add `git-lfs` to `nix/hosts/cc-ci/configuration.nix` `environment.systemPackages` and
-rebuild + apply. This is a host change (orchestrator-driven per plan §9, host changes only via
-NixOS/git) but you own the nix config — file it if needed, or add it yourself if it's
-declarative-idempotent (it is).
-
-Verified: `nix/hosts/cc-ci/configuration.nix` has only `curl git jq openssh`; `nix/modules/packages.nix`
-is abra-overlay only. Neither includes git-lfs.
-
-## Issue 2: Double /api/v1 path in test_lfs_roundtrip.py JWT-stability poll [BUG]
-
-In `test_lfs_roundtrip.py`, the `_api()` wrapper adds `/api/v1` prefix. But the restart
-health-poll at line ~184 calls:
-```python
-status2, _ = _api(live_app, "/api/v1/version", ...)
-```
-This produces URL: `https://{domain}/api/v1/api/v1/version` → 404 forever.
-The restart wait loop will spin for 120s then fail with "gitea did not come back up after restart"
-even if gitea is healthy.
-
-Fix: change the path to `"/version"` so the URL is `/api/v1/version`.
-
----
-
-These are my independent pre-M1 findings. Neither blocks M1 (LFS test skips on main). I'll
-include both in my M1 REVIEW if they're still present at claim time, and they MUST be fixed
-before the M2 LFS capstone runs on lfs-plain-gitea.
