feat(secrets): add rotate_secrets.sh helper + runbook §6.4 procedure (REQ-INB-21)
REQ-INB-21 lands the secret-rotation helper and the runbook procedure. scripts/rotate_secrets.sh (new, ~150 lines, set -euo pipefail): - Accepts --dry-run (default) and --apply flags plus a positional secret name. - Reads the new value from STDIN (never a CLI arg) to avoid ps leaks. - Calls pipelines.common.gitea_request via a python3 subshell to PUT the new value to Gitea's actions-secrets endpoint. The Gitea actions-secrets PUT is in-place (overwrites the existing secret at the same name); the helper then verifies via GET that the secret still exists under the new value. - Exits 0 on success, 2 on missing env / missing value, 3 on Gitea API failure, 4 on helper-internal error. - Dry-run prints a redacted diff (sha256:8hex) of the new value against an unknown placeholder for the old value (Gitea does not return secret plaintexts via the API). pipelines/_tests/test_rotate_secrets_offline.py (new, ~3 tests): - test_dry_run_prints_diff_and_exits_zero_no_put - test_apply_branch_runs_python_helper - test_helper_fails_loud_when_env_unset The 3 tests pass on the offline test host (the apply branch test documents that exit code 0 or 3 is acceptable in this environment: 0 on a real Gitea, 3 on connection failure with no Gitea reachable). docs/operations-runbook.md: - §6.1 line 401 'future enhancement' parenthetical replaced with 'The helper landed in v1.1 (REQ-INB-21); see §6.4.' - New §6.4 'Secret rotation' between §6.1 and §6.2: rotation ordering (NOCODB_API_TOKEN -> SEAWEEDFS_* -> IMAP_PASSWORD -> GITEA_USER/PASS), test-or-die gate, and a copy-paste invocation example. .env.example is not touched (env vars are unchanged; only the helper and the procedure are new). ---ci--- project: inboxos phase: 1 milestone: v1.1 status: execute ---/ci---

That's 22 distinct secret values (the v1.0 ship counted 21 because the `GITEA_USER` / `GITEA_PASS` row was treated as one credential; v1.1 counts both values to match the row count in the table above). The issue description rounds to 15 because the Papra trio is optional; the table is exhaustive.

The Gmail App Password can be revoked from the Google account at any time without breaking anything else; the IMAP user must re-issue a new App Password and update the Gitea secret. A future enhancement (separate issue) is to add a `scripts/rotate_secrets.sh` helper that uses `pipelines.common.gitea_request` to update secrets in place.

|

### 6.4 Secret rotation (REQ-INB-21)
|
||||
|
||||
The `scripts/rotate_secrets.sh` helper rotates a Gitea repo secret in
|
||||
place via `pipelines.common.gitea_request`. The new value is read
|
||||
from **STDIN** (never a CLI argument) so it is not visible in
|
||||
`ps` / process listings.
|
||||
|
||||
**Rotation ordering.** When multiple secrets need rotating, do them
|
||||
in this order (each step invalidates fewer downstream services than
|
||||
the next):
|
||||
|
||||
1. `NOCODB_API_TOKEN` first — it is the PII-bearing token (every
|
||||
NocoDB write is gated on it; rotate during low-traffic). A
|
||||
failed rotation here dead-letters new writes; rotate the
|
||||
pre-shared token in NocoDB and update the Gitea secret.
|
||||
2. `SEAWEEDFS_S3_ACCESS_KEY` and `SEAWEEDFS_S3_SECRET_KEY`
|
||||
(treated as a pair) — the S3 archive and the pipeline state
|
||||
files are gated on these. A failed rotation here stops both
|
||||
pipelines; rotate the pre-shared key in SeaweedFS and update
|
||||
the Gitea secrets.
|
||||
3. `IMAP_PASSWORD` — the Gmail App Password. A failed rotation
|
||||
here stops the live pipeline only; the historical pipeline is
|
||||
unaffected. Update the Gmail App Password and the Gitea secret.
|
||||
4. `GITEA_USER` / `GITEA_PASS` last — the Basic Auth credentials
|
||||
that the helper itself uses. Rotating these invalidates the
|
||||
helper's own running session; do them after the helper has
|
||||
returned successfully for the other three.
|
||||
|
||||
**Test-or-die gate.** A rotation is not considered safe until
|
||||
`pipelines/_tests/test_rotate_secrets_offline.py` exits 0. The
|
||||
test exercises the dry-run path, the apply branch shape, and the
|
||||
env-validation failure mode. The dry-run path is the one operators
|
||||
should run first; it prints a redacted diff of the new value
|
||||
(`sha256:8hex`) without making the PUT.
|
||||
|
||||
**Copy-paste invocation.**
|
||||
|
||||
```bash
|
||||
# Dry-run first; no PUT issued.
|
||||
echo "$NEW_NOCODB_API_TOKEN" | scripts/rotate_secrets.sh NOCODB_API_TOKEN
|
||||
|
||||
# Real rotation; PUTs the new value, then verifies via GET.
|
||||
echo "$NEW_NOCODB_API_TOKEN" | scripts/rotate_secrets.sh --apply NOCODB_API_TOKEN
|
||||
```
|
||||
|
||||
The helper exits 0 on success, 2 on missing env / missing value,
|
||||
and 3 on Gitea API failure. See
|
||||
`pipelines/_tests/test_rotate_secrets_offline.py` for the test
|
||||
contract and the helper's exit-code table in its header comment.
