Implement Checkpoints v1.1 Topology Coverage

Using using-superpowers for skill routing and pfleidi:pfleidi:review for the review workflow. I’m going to anchor the review on the spec, the current origin/main diff, branch commits, and any PR context before launching the parallel review agents.

The branch has 9 changed files against origin/main and no uncommitted changes. gh pr view could not resolve a GitHub PR for this remote, so PR context will be recorded as unavailable rather than guessed.

I’ve read the spec’s key decisions: topology-aware reads for rewind prompt and cleanup orphan detection, explicit v1-pinning for resume/explain, and deletion of the dead session-listing chain. I’m going to pass that as review intent rather than treating all old v1 reads as regressions.

Changed files against origin/main (9 total): explain.go, resume.go, strategy/clean_test.go, strategy/cleanup.go, strategy/common.go, strategy/manual_commit_rewind.go, strategy/manual_commit_test.go, strategy/session.go, and strategy/session_test.go.

I’m launching the review agents now with that context and the spec as the statement of intent.

The spec leaves one accepted risk: v1.1 cleanup can flag a false orphan if the mirror is stale. I’m telling the review agents to treat that as intentional, so only contradictions, concrete bugs, or real test gaps should surface as findings.

The first-pass agents are running. While they do the lens-specific passes, I’m reading the same changed paths locally so I can verify or discard their findings instead of forwarding raw agent output.

One thing I’m checking carefully is the new rewind test setup. It intentionally hand-builds a checkpoint tree instead of using WriteCommitted; I need to confirm that tree shape matches the real prompt-reading helper and still proves the intended topology behavior.

The local pass confirmed the helper rename itself is mechanically small. The likely review surface is now the two new tests and whether the cleanup read switch still handles multi-session checkpoint references correctly.

The rewind test is narrower than the production storage layout: it hand-builds a root prompt.txt because the current picker helper reads that path for single-session logs-only points. I’m tracing whether that narrowness is just a topology isolation choice from the spec or whether it leaves the actual intended behavior unverified.

The spec’s new rewind test setup does not match the spec text: the spec says to use WriteCommitted, but the implementation hand-builds a different tree shape. That matters because production committed checkpoints store prompts under session subdirectories, and the picker’s single-session path currently reads the root path.

The security reviewer came back clean. My local source trace has one concrete issue candidate: the new rewind test proves the ref switch only against a hand-built tree shape, not the real committed checkpoint layout produced by WriteCommitted.

A second candidate is in cleanup: ListCommitted exposes all session IDs for multi-session checkpoints, but orphan detection only records cp.SessionID, the latest session. Since this branch explicitly moves that cleanup path, I’m checking whether that should be reported as a current required fix or treated as older behavior outside the branch’s scope.

One reviewer independently found the rewind test/layout issue and classified it Required. I’m still waiting on the remaining reviewers before I synthesize; I’m also checking whether the minimal fix can reuse existing committed-read helpers instead of adding a new path reader.

The clean-Go reviewer reported no findings, and their focused tests passed, but that doesn’t disprove the layout gap because the current test encodes the non-production layout. I’m treating test output as useful smoke evidence, not as proof the intended behavior is covered.

The correctness reviewer found a docs/API drift issue from deleting exported session-listing functions while docs still advertise them. I need to verify that against the source docs and decide whether it belongs in the fix batch, since it is caused by this branch even though the docs are not in the current diff.

All first-pass agents are back. I’m starting the independent coverage sweep now, then I’ll synthesize only source-backed findings I can confirm locally.

Two findings remain under verification: the rewind prompt layout gap and stale docs for deleted exported APIs. I’m reading the cited docs and nearby production helpers now to confirm exact line references and minimal fixes.

I confirmed the docs drift: AGENTS.md is a symlink to CLAUDE.md, and both the repo instructions and architecture doc still list ListSessions() / GetSession() after this branch deletes them. That is branch-introduced documentation/API drift, not just stale background text.

The prompt reader issue is broader than just single-session. Existing ReadAllSessionPromptsFromTree also assumes the latest multi-session prompt is at the checkpoint root, while committed checkpoints are written under numbered session directories. The smallest production fix is likely to reuse the existing committed-layout helper for the main prompt and make the all-prompts helper read numbered session directories.

A project-local tmp/ directory exists and is ignored, so if I apply default fixes I’ll keep the review ledger under tmp/pfleidi-review/ per the review workflow.

The coverage sweep confirmed the prompt-layout issue as Required and eligible. I’m going to fix two Required items: read logs-only rewind prompts from the real committed checkpoint layout and update the docs that still advertise deleted APIs.

Required

Improvements (follow-up)

Summary: 2 Required findings and 1 follow-up improvement. The branch should not merge until the prompt reader/test mismatch and docs drift are fixed; both Required fixes are source-backed and minimal.

Planned Autofix

I’m applying the eligible Required fixes now and leaving the comment-only improvement untouched unless it falls directly out of the required edit.

I’m creating the review ledger under the ignored tmp/pfleidi-review/ directory, then I’ll do the red test change first so the prompt issue is proven before touching production code.

I’m changing only the v1.1 rewind test first: it will write the checkpoint through WriteCommitted, mirror that real committed tree, and keep v1 pointed away. With production code unchanged, that should fail on the prompt assertion.

The test now uses the production committed checkpoint writer. I’m running just that test to confirm it fails for the expected reason before changing the reader.

The first red test covers the single-session path. Before production code, I’m adding one focused helper test for the multi-session prompt list so the other half of the same root cause is covered too.

I’m running the new helper test by itself to verify it also fails against the current implementation.

Both prompt tests fail for the expected layout mismatch. I’m now making the minimal reader changes: single-session logs-only points use the committed-layout latest-session helper, and multi-session prompt lists read numbered session directories.

The production reader now follows the committed layout. I’m rerunning the two tests that were red before.

The prompt fix is green on the focused tests. I’m updating the docs next so they no longer describe the deleted session-listing API.

The actual strategy interface still has GetSessionLog() and GetSessionInfo() but not the deleted standalone discovery functions. I’m aligning the prose with that rather than inventing a replacement API.

I’m keeping the doc edit narrow: remove the deleted discovery APIs from the strategy interface summary and replace the architecture section with the actual state-store / committed-read-store paths.

The docs no longer reference the deleted APIs. I’m formatting the touched Go files, then I’ll run focused verification for the prompt fix and a doc grep check for the API references.

gofmt completed, and the deleted API names no longer appear in the affected docs (rg exited 1 with no matches, which is expected for this check). I’m recording the fix ledger before running the remaining validators.

For verification I’m using focused Go tests for the changed strategy package and the project lint task because the documented lint wrapper does not appear to have file-level scoping in the repo docs.

One compatibility detail: the old code could read a root-level prompt if such metadata existed. I’m preserving that as a fallback after the committed-layout read, so the fix doesn’t narrow old readable shapes while correcting the production layout.

I added the root fallback and am reformatting that file before validators.

I’m running the focused strategy tests, lint, a whitespace check, and the doc reference grep from the same tree state. If lint surfaces unrelated pre-existing issues I’ll separate them from anything introduced here.

Verification passed: focused strategy tests and mise run lint exited 0; git diff --check exited 0; the doc grep exited 1 with no output, which is the expected “no matches” result for removed API references. I’m doing a final diff/status review and updating the ledger.

The reviewed diff is limited to the required fixes and related tests/docs. I’m updating the ledger with the final verification evidence now.

The ledger is updated. Before I close this out, I’m applying the verification-before-completion checklist so the final status only claims what the commands actually showed.

Applied the two Required review fixes. No commits were made.

Red checks before the fix failed as expected: the v1.1 rewind test got an empty prompt, and the multi-session helper returned an empty second prompt.

Rollback notes:

Ledger: review-cli-20260603-162626.md

I’ll commit only the tracked review-fix files, then push HEAD to origin. I’m re-checking the current diff/status first so the commit reflects the actual working tree, not stale assumptions.

The staged set will be the six tracked files shown in the diff. I’m committing them as one focused review-fix commit; the ignored ledger under tmp/ is not part of the commit.

I’ll fix item 3 as a separate small commit since the first commit already exists and has not been pushed. Then I’ll run the required lint check on the final tree and push both commits.

I’m changing only the stale comments in cleanup.go; the code path already uses the topology read store.

The comment-only fix is in place. I’m formatting the touched Go file and then running the required final lint before committing and pushing.

Only cleanup.go has unstaged changes now, and they are comment-only. I’m checking that diff and running mise run lint on the final tree before the second commit.

mise run lint passed on the final tree. I’m committing the comment cleanup now, then I’ll push HEAD to origin.

Both local commits are created. I’m checking the branch state, then pushing the current HEAD.

The working tree is clean. The two commits to push are 3283c77d2b fix logs-only prompt reads and ce29f8380d update cleanup topology comments.

Committed and pushed.
