github-backup: drain-wrapper Bitwarden fallback (PRs #3222/#3226) has no test — the bws-env branch runs only where the primary path already failed

Finding

infra/github-backup/systemd/drain-wrapper.sh — the systemd drainer's only Bitwarden credential path for the github-backup estate mirror — had its credential-loading logic changed twice in one evening, and none of it is tested:

PR github-backup: portable Bitwarden env in drain wrapper #3222 (github-backup: portable Bitwarden env in drain wrapper #3222, commit a0d2da4) replaced the hard source ~/tools/bws-env.sh with a three-way branch (sandbox ~/tools, laptop ~/hatch/tools, raw access-token file).
PR github-backup: drain wrapper bws access fix (laptop token store) #3226 (github-backup: drain wrapper bws access fix (laptop token store) #3226, commit 6361b89) replaced that again: export ~/.config/bws/access-token when present, then probe bws secret list and only on failure source a bws-env.sh from either candidate path, with sourcing failures masked (source "$f" || true).

Both PRs touched only drain-wrapper.sh (verified from both merge commits' file lists). On current main (3adad8fc9e2e) the fallback logic is at drain-wrapper.sh:11-18, and there is no test for the wrapper anywhere in the repo: infra/github-backup/systemd/ contains no test file (directory listing verified), and a code search for drain-wrapper returns only nixos/home/github-backup.nix and the drain service unit.

Why it matters

The fallback branch is precisely the code that runs only on a machine where the primary credential path has already failed — the situation both PRs were written for (the laptop drain). Its failure modes are silent or late:

If bare bws fails and bws-env.sh is missing or itself fails, the || true mask lets the script continue to the Python eval, which then dies with a raw traceback/KeyError at timer fire time, not at deploy time.
Path drift (the wrapper already moved conventions once: ~/tools vs ~/hatch/tools vs ~/.config/bws) breaks the fallback without any signal until a drain run fails and the estate mirror silently stops draining.

The sibling scripts in this fleet's backup tooling carry stubbed tests (e.g. pkgs/cold-store-reaper/tests/); the drain wrapper — which handles live credentials — has none.

Acceptance criteria

A stubbed shell test for drain-wrapper.sh (fake HOME, stub bws, stub drain target — no real Bitwarden, no network) covering all four branches:
1. BWS_ACCESS_TOKEN already set in the environment → no token-file export, no bws-env.sh sourcing, drain proceeds.
2. Token file present at ~/.config/bws/access-token → exported, bare bws succeeds, no fallback sourcing, drain proceeds.
3. Bare bws secret list fails and a bws-env.sh exists (each candidate path) → it is sourced, credentials load, drain proceeds. This is the PR github-backup: drain wrapper bws access fix (laptop token store) #3226 branch that currently has zero coverage.
4. No working credential path → the wrapper exits non-zero before invoking the drain, with a comprehensible error.
The test runs in the same place/convention as the repo's other shell-script tests and passes.
Production behavior of drain-wrapper.sh is unchanged unless a branch is shown broken by the new test, in which case the fix is part of this issue.

Found by pr-diff-review lane B reviewing PRs #3222 and #3226 (batch 3217–3251, 2026-11-03). Cross-checks that this is not already covered: open tracker issue #3215 (estate mirror system) does not mention wrapper tests; issue #3240 covers non-atomic state JSON writes in the fetch/drain scripts, a different defect.

Task: Filed this issue after reviewing PRs github-backup: portable Bitwarden env in drain wrapper #3222 and github-backup: drain wrapper bws access fix (laptop token store) #3226 in lane B's batch 3217–3251: the drain wrapper's Bitwarden loading was rewritten twice in one evening and no test for it exists on main (verified: both merge commits touched only drain-wrapper.sh; systemd directory listing and code search show no test). Triage packet enqueued as task 8959 in repo-health-code-pilot.
Expectation: effort/s — a stubbed four-branch shell test for drain-wrapper.sh; done when all four credential branches are covered and the test passes without real Bitwarden or network.

Verdict: CONFIRMED at current main (f486f2aab6a98cf709a4b37659441f318eafa0f8). Fresh reads this run:
- infra/github-backup/systemd/drain-wrapper.sh on main carries exactly the filed credential logic: token-file export first, then a probe of the bare credential CLI, and only on failure a masked, non-fatal source of a fallback env script from either candidate path (lines 11–18, matching the issue's evidence).
- infra/github-backup/systemd/ on main contains only the wrapper, the service/timer units, and install-units.sh — no test file.
- No branch of that fallback logic has any automated coverage; branch 4 of the acceptance criteria (no working credential path) currently continues past the masked source toward the drain invocation rather than exiting early with a comprehensible error — the follow-up test will pin the expected behavior and any fix it demonstrates.
Routing: the stubbed four-branch shell test is well-scoped and low-risk; enqueued as a follow-up small_fix queue task by this triage (see the queue task id in the completion of task 8954). Production behavior stays unchanged unless the new test demonstrates a broken branch.
