review(rcust): APPROVE lasuite-drive pre_install fix-forward (scoped to line-54 bucket-poll raise→best-effort; verified old=best-effort, custom MinIO test is real gate, no coverage loss); conditioned on L5 re-run + my diff re-verify. Auditing other shell->python hook ports for same drift

-## [builder @2026-06-10T20:52Z] lasuite-drive: GENUINE rcust regression found — trivial fix-forward proposed, requesting approval
-
-Root-caused the deterministic lasuite-drive install-tier RED (m2r + m2rr identical): my P2b port
-of `setup_custom_tests.sh` → `ops.py::pre_install(ctx)` was NOT semantics-preserving.
-
-- OLD (c2508c7 `tests/lasuite-drive/setup_custom_tests.sh`): scale the minio-createbuckets
-  one-shot, poll the bucket up to 90s, `break` on success — and on timeout FALL THROUGH and print
-  "complete" (best-effort by design; the custom-tier MinIO storage test is the real gate for a
-  genuinely missing bucket).
-- NEW (my port in `tests/lasuite-drive/ops.py::pre_install`): same scale+poll, but
-  `raise AssertionError` on timeout → install tier fails.
-- Live evidence the semantics change is the ONLY problem: in BOTH failed runs the bucket appears
-  shortly after the 90s window and every later tier INCLUDING the custom MinIO test passes
-  (m2r-lasuite-drive level=0 but upgrade/backup/restore/custom all pass; identical serially).
-  Old code would have printed the fall-through line and gone green, as its baseline did.
-
-Proposed fix-forward on main (trivial, restores OLD behavior byte-for-byte in semantics):
-in `pre_install`, replace the terminal `raise AssertionError(...)` with a loud
-`print("  !! pre_install: minio-createbuckets one-shot did not create drive-media-storage in 90s "
-"— continuing (best-effort, as the pre-restructure hook did); the custom-tier MinIO test gates "
-"a genuinely missing bucket", flush=True)` and return. No assertion weakened: the pre-restructure
-path had NO assertion here, and the custom-tier MinIO test (the actual gate, unchanged) still runs.
-
-Per plan M2 rules (fix-forward on main only for trivial breakage WITH Adversary approval): please
-approve/deny. On approval I'll commit `fix(tests): restore best-effort semantics of lasuite-drive
-pre_install bucket trigger (rcust M2 regression)` + a serial lasuite-drive re-run as proof.
-
-Meanwhile tests 2+3 are running (baseline-REF runs m2b-*, then old-main A/B ab-*-oldmain).

+## [adversary @2026-06-10T20:53Z] lasuite-drive pre_install fix-forward: APPROVED (scoped + conditioned)
+
+Independently verified your root cause — it's correct and it's a GENUINE rcust regression (good
+catch + honest disclosure):
+- OLD c2508c7 setup_custom_tests.sh: 90s bucket poll, `break` on success, on timeout FALLS THROUGH
+  to the "complete" echo — NO failure (best-effort by design; the comment says the MinIO storage
+  test is the gate). Confirmed.
+- NEW merged-main ops.py pre_install line 54: same poll then `raise AssertionError` on timeout →
+  install RED. The lone behavioral change. Confirmed.
+- test_minio_storage.py (custom tier) is the real gate and is UNCHANGED: confirms bucket +
+  upload→list→download round-trip, so a genuinely-missing bucket is still caught (at custom tier,
+  exactly as old). No coverage weakened; L5 level semantics preserved.
+
+**APPROVED** as a trivial fix-forward (vs revert) — restoring pre-restructure best-effort semantics.
+
+SCOPE (strict): change ONLY the terminal `raise AssertionError(...)` at the END of `pre_install`
+(the bucket poll, line ~54) → loud `print(...)` + `return`. Do NOT touch `_wait_collabora_ready`'s
+`raise AssertionError` (line ~75) — that's a legitimate pre_upgrade readiness gate that MUST keep
+failing if collabora never boots. No other edits, no test changes.
+
+CONDITIONS before it counts toward M2 PASS:
+1. Serial lasuite-drive re-run at its baseline REF returns L5 (install pass + custom MinIO test pass).
+2. I independently re-verify: the one-hunk diff is exactly as scoped, AND the re-run hits L5.
+This is the ONLY fix-forward I pre-approve; any further regression needs separate approval.
+
+NOTE for the rest of M2: this slipped my M1 review because my coverage diff compared recipe_meta
+KEYS, not ops.py hook BODIES, and my assert-scan matched `assert ` not `raise AssertionError`. So I
+am now auditing ALL the shell→python hook ports (lasuite-docs setup_custom_tests.sh→install_steps.sh
++ ops.py, and every ops.py pre_* across recipes) for the same best-effort→fatal / semantics drift —
+independently of your sweep. Will report anything I find as its own finding.
