feat(recover): synthetic rehearsal test + operator rehearsal playbook (#90)#124
Conversation
…#90) Close #90's testing gap in two layers: a synthetic CI-guard test and an operator playbook for the real crates.io-backed rehearsal. ## Synthetic test (crates/shipper-cli/tests/e2e_rehearse.rs) The existing `bdd_resume` scenarios prove the resume *read* side: given a hand-constructed state file, assert resume does X. They do NOT prove the *write* side — that a real `shipper publish` run's persisted state is actually coherent when the run is interrupted. The new `rehearsal_interrupted_publish_then_resume_preserves_invariants` closes that gap end-to-end: 1. 3-crate workspace (a, b, c with c→b→a) — real topological ordering. 2. Mock registry with per-crate 404→200 flip + a `never_flip` pin so crate-c stays 404 during run 1 even after cargo "exits 0", preventing the reconcile path from upgrading a test-simulated failure to Published. 3. Run 1: fake cargo succeeds for a/b, fails for c → realistic interrupted end state. 4. Assert on persisted evidence: - state.json parses, a/b=published, c not published - events.jsonl is valid NDJSON (append-only integrity) - PackagePublished event count == succeeded crate count (no duplicates) 5. Run 2: shipper resume with c now succeeding. 6. Assert post-resume: - a/b stay Published (in-state idempotency) - c reaches Published or Skipped (both legitimate — the version_exists short-circuit is a valid end state) - PackagePublished total across runs is 2..=3 (never >3 — duplicates would mean resume re-published already-done crates) - ExecutionStarted event count == 2 (events.jsonl is append-only — truncation would drop events from run 1) This runs on every CI commit as a cheap regression guard. ## Real-rehearsal playbook (docs/how-to/run-recover-rehearsal.md) Step-by-step procedure for the actual crates.io-backed rehearsal that the synthetic test can't simulate: - throwaway `v0.3.0-test-resume-YYYYMMDD` tag - trigger release workflow; cancel after 2-3 crates published - collect shipper-state-final artifact; verify NDJSON + event/state consistency - dispatch resume; verify plan-ID validation, skip-already-published, no duplicate cargo publishes - spot-check crates.io visibility - yank the rehearsal versions (containment, not deletion) - pass/fail rubric + "when to re-run" policy The playbook is linked from docs/README.md's How-to index. ## Scope Synthetic test proves state/events invariants. Real rehearsal proves crates.io rate-limit interaction, sparse-index propagation, runner killed-mid-upload artifact preservation — things the mock can't reach. Both together = #90's "resume is demonstrated, not promised."

Code Review
This pull request introduces a new end-to-end 'Recover rehearsal' test and documentation to verify that the publishing process can be safely resumed after an interruption. The changes include a synthetic test using a mock registry and a detailed manual procedure for testing against crates.io. Feedback was provided regarding a docstring that incorrectly mentions unimplemented event types, an inconsistent crate count in the documentation, and incorrect file paths in the maintenance section of the new guide. Additionally, it was suggested to make the crate list in the manual procedure dynamic to prevent the documentation from becoming brittle.

The docstring mentions that PackageSkipped events are emitted for a/b during resume. However, the pull request description explicitly states that the resume path currently does not emit PackageSkipped events for packages already in the Published state, and that this is a candidate for a follow-on enhancement (#93). Additionally, the test code does not currently assert the presence of these events. This comment should be updated to reflect the current implementation to avoid misleading future maintainers.

There is an inconsistency between the stated number of crates and the list provided later in the document. Line 18 (and lines 123, 179) mentions "12 crates", but the loop in Step 8 (lines 139-142) and Step 9 (lines 153-156) lists 13 distinct crate names. Please verify the correct count and update the documentation accordingly.

The list of crates in this playbook is hardcoded, which makes the documentation brittle as the workspace evolves. Consider suggesting a dynamic way to retrieve the list of workspace members (e.g., using cargo metadata --format-version 1 | jq -r '.workspace_members[] | split(" ")[0]') or adding a note for the operator to verify the current list of crates in the workspace.

The paths referenced here (crates/shipper-core/src/...) appear to be incorrect based on the repository structure described in GEMINI.md and the provided file list, which indicate that the core logic resides in crates/shipper/src/. Please verify if shipper-core is the intended path or if it should be updated to crates/shipper/src/.

Enforce idempotency per crate, not by aggregate count
This assertion can miss a duplicate publish regression on resume: if crate-a (or crate-b) is incorrectly re-published while crate-c is skipped, the total PackagePublished count is still 3, which this check accepts. That means the test passes even though resume violated idempotency for an already-published crate. To actually guard the invariant described in the comments, the test should validate PackagePublished occurrences by package (e.g., crate-a@0.1.0 and crate-b@0.1.0 appear exactly once across both runs).
Useful? React with 👍 / 👎.

Three-column reconciliation of what's actually merged vs each issue's acceptance checklist. Single source of truth for what closes each pillar issue. **Findings:** - **#90 Recover** — honestly closable. Code side is done (#124 + #130); operator-side real rehearsal is an ops action, not a code gap. - **#97 Prove tier 2** — 85% done. Rehearsal + visibility + hard gate + plan_id binding all landed (#127 + #133). Missing: install/smoke check (cargo install against the rehearsal registry / consumer build). One narrow follow-up PR closes it. - **#98 Remediate** — 60% done. Receipt schema + plan-yank (from-receipt) + yank primitive + fix-forward planning all landed (#121 + #132 + #134). Missing: plan-yank's --starting-crate graph mode, plan execution for yank + fix-forward. Two narrow follow-ups. Also captures the two review concerns on #122 (Trusted Publishing) that were addressed in a follow-up commit to that PR. Recommended next merge order and follow-up PRs spelled out at bottom.

Summary
Close #90's testing gap in two layers:
crates/shipper-cli/tests/e2e_rehearse.rs.Runs on every commit. Proves the write-side invariants (state.json,
events.jsonl NDJSON integrity, no duplicate publishes on resume) that
existing
bdd_resumetests don't cover because they construct stateby hand rather than running a real publish.
docs/how-to/run-recover-rehearsal.md.Step-by-step for the once-per-RC crates.io-backed rehearsal the
synthetic can't substitute for (rate limits, sparse-index timing,
runner kill + artifact upload).
Why both
The synthetic test catches persistence bugs cheaply and repeatedly.
The real rehearsal catches the things mocks literally can't simulate —
crates.io's per-minute new-crate rate limit, sparse-index propagation
delay, the GitHub Actions `if: always()` artifact upload path after a
cancelled job, token/auth edge cases.
Running only one is insufficient:
through (see: ci: reduce PR proptest cost, add Ubuntu-only full-strength crypto lane #87, docs: add operator release runbook #88, ci: include .shipper/ hidden dir in release workflow artifact uploads #89 — all found by CI reality, not mocks).
The synthetic test
rehearsal_interrupted_publish_then_resume_preserves_invariants:crate-c stays unpublished during run 1 even if cargo "exits 0"
(otherwise the reconcile path would upgrade the simulated failure
to Published and the scenario becomes meaningless)
PackagePublished; events.jsonl append-only (ExecutionStarted count = 2
confirms run 1's events survived resume)
The playbook

Findings noted during test development
Two potential improvements surfaced while writing the test, kept out of
scope for this PR:
PackageSkipped event for packages whose state is already Published
(only emits for packages where `version_exists` short-circuits).
The audit trail is silent on the "state said done, we trusted it"
decision. Candidate enhancement for an Document and enforce the events-as-truth / state-as-projection invariant #93 follow-on.
state.json kept showing `failed` for the affected package. Top-level
`updated_at` bumped (state file was re-written) but the package's
own `last_updated_at` didn't. Could indicate update_state not being
called on the Skipped path for a resumed Failed package — worth a
closer look.
Both warrant follow-up issues, not blockers here.
