Simplify Git Worktree Ignore Configuration

Using pfleidi:review for the requested branch review; I’ve loaded the review workflow and I’m gathering the current origin/main diff and intent context now. Dungeon paperwork, but the kind that catches teeth in the gears.

Diff scope is four Go files under cmd/entire/cli, about 1,047 inserted lines and no working-tree dirt. PR lookup failed because this checkout’s remotes aren’t recognized by gh, so the review intent will be inferred from commits and diff unless source says otherwise.

I loaded the Go, de-slop, and testing guidance the review workflow delegates to. Since this branch is all Go, the Go-cleanliness lens is part of the swarm.

I’m also pulling the live trail command help because this branch changes that surface. If the command contract moved, the review needs the current Cobra truth, not vibes in a little hat.

trail exposes checkout, so I’m drilling one level deeper before sending the agents. This is exactly the sort of flag-surface branch where stale help text lies with confidence.

Review context before launch:

Changed files: 4 total, all Go. Launching security, correctness, de-slop, readability, and clean-Go lenses now.

Agents are out. I’m doing the main-pass source read in parallel, focused on the changed production files first, so the final report isn’t just a chorus of outsourced suspicion.

The main source pass has one real suspicion already: the installed agent-help trail checkout output still lacks --worktree, while the branch source registers it. I’m checking whether that’s just an installed-binary mismatch or a source/help wiring issue before treating it as a finding.

The live installed help mismatch looks like the binary in PATH, not the branch source: newTrailCheckoutCmd does register --worktree, so I’m not treating that as a source bug. The actual dungeon floor is now worktree path handling and .worktreeinclude copy behavior.

One high-value edge is whether git rev-parse --git-common-dir is resolved from a subdirectory correctly. The code joins relative output to CWD, so if Git returns .git from a nested directory, the feature builds worktrees under the wrong root. I’m verifying that against real Git behavior now.

In this linked-worktree checkout Git returns an absolute common dir, so the local branch passes that check. I’m testing a fresh normal repo too because this feature is meant to run from either shape, and Git’s relative-path behavior is where pain likes to live rent-free.

I’m checking .worktreeinclude pattern semantics now. The docs in source promise “gitignore-style patterns,” so a directory pattern like config/ must behave like people expect, not like a tiny bureaucratic trapdoor.

That search only hit an old module-cache path because shell expansion did what shell expansion does. I’m narrowing it without cleverness now; yes, the command got dramatic for no reward.

Go target is 1.26.4, and the repo uses go-git v6 alpha from May 2026. I’m checking behavior against that exact dependency, not a convenient memory of gitignore semantics from another universe.

Subagents are still running; I’m continuing the local pass on helper behavior. So far, the scary-looking symlink and branch-name paths are deliberately guarded; the remaining candidates are narrower pattern semantics and comment/test quality.

No need for a throwaway probe file; the go-git matcher source is readable enough. I’m checking dirOnly handling directly so I don’t invent a bug with a tiny lab experiment and call it science.

Security reported two source-backed findings; I’m verifying both locally before they make the final table. The second one is especially nasty: copying .env into a branch that doesn’t ignore .env is how secrets become “surprise collectibles.”

I’ve verified the destination-ignore finding against the current tests: the “creates worktree” test creates the trail branch before adding .gitignore, then expects .env to be copied anyway. That is not a theoretical bug; it’s currently encoded as success. Bold, and useful.

De-slop and clean-Go both came back clean, so the review is converging on the two security findings unless correctness or the coverage sweep finds another confirmed issue. I’m checking autofix scope now because both fixes look small and testable without touching public APIs.

Correctness found a third Required issue: duplicate ignore lines can be treated as already handled even when a later negation makes the path unignored. I’m launching the independent coverage sweep now; then I’ll verify and dedupe the confirmed set before fixing eligible Required items.

Before editing I’m loading the local code-review-receipt/TDD guardrails because the next step is applying review findings, not just admiring them in a glass case. The fix path is small, but the rules still count.

The fix cycle will use TDD: add focused regression tests for the confirmed failures, watch them fail, then make the minimal production changes. No commits; just a review patch if the findings stay eligible after the coverage sweep.

Coverage sweep is still running. I’m using the wait time to check artifact availability and exact verification scope, so once the report is ready the fix cycle doesn’t wander off into a swamp.

./tmp/ exists and is ignored, so I’ll use ./tmp/pfleidi-review/ for the required fix ledger once we enter edits. The verification path is the cmd/entire/cli package with focused trail_checkout_worktree tests, plus build/lint after the patch.

Coverage sweep returned clean. Final confirmed set is three Required findings: .gitignore symlink write, ineffective duplicate ignore append after negation, and copying included files into destination branches that do not ignore them. All three are autofix-eligible; I’m presenting the review tables, then applying the focused fixes.

Required

No Improvement findings survived verification. Overall: 3 Required, 0 Improvements. The branch is not merge-ready until these are fixed; the pattern is all local filesystem safety around generated worktrees.

Planned Autofix

Adding regression tests first: one for unsafe symlinked ignore files, one for negated ignore rules, and one for destination worktrees that would not ignore an included file. These should fail on the current code; if they don’t, the test is theatrical garbage.

One test referenced the planned helper before it exists, which would make RED a compile error instead of a behavioral failure. Fixing the test to exercise the existing appendIgnoreRule path before running the red check.

Running the focused red test set now. Expected failures: symlink append succeeds, negated ignore remains unignored, and destination-unignored files still copy.

Red run failed before tests executed: the unquoted regex was eaten by the shell, and Go’s build cache is outside the sandbox. Re-running the same focused test correctly quoted and with approval for the build cache access.

The red run caught the expected behavior failures, plus one bad test setup: this repo helper doesn’t create .git/info until needed. I’m fixing that setup so the negation test fails for the right reason, not because it tripped over an absent directory.

Re-running the red check after fixing the test setup. It should now fail only on the three real behaviors.

Production changes now: make ignore-file appends refuse symlinks/non-regular files, force a final effective rule only after Git proved the path is unignored, and gate .worktreeinclude copies on the destination worktree’s ignore rules.

Running the same focused set for GREEN. If this passes, I’ll run the broader local worktree checkout tests and then format/build/lint scope.

The red-green check passed: command go test ./cmd/entire/cli -run 'Test(AppendIgnoreRule_RejectsSymlink|EnsureTrailWorktreeIgnoreRule_AppendsAfterNegatedRule|CopyWorktreeIncludeFiles_SkipsDestinationUnignoredFile|CheckoutTrailWorktree_SkipsIncludeWhenTrailBranchDoesNotIgnoreFile)' -count=1 exited 0 with ok github.com/entireio/cli/cmd/entire/cli 0.633s. Formatting the touched Go files next.

Go formatting made no noisy output. I’m reviewing the resulting diff before broader verification, because “formatted” and “correct” are different little bureaucratic demons.

Diff review looks scoped to the three findings. Running the full focused worktree-checkout test cluster now, including the adjusted positive copy cases.

Focused worktree test cluster passed: command exited 0 with ok github.com/entireio/cli/cmd/entire/cli 1.101s. Updating the review ledger, then I’ll run compile/build and lint/test verification.

Running the remaining validators at the natural boundary: explicit CLI build and the project lint task. The focused tests are still valid from the last run because only the ledger changed afterward.

Build and lint both exited 0. I’m checking the working tree now for generated artifacts, because go build ./cmd/entire can leave a local binary behind depending on invocation.

go build left an ignored ./entire binary. I created that artifact, so I’m removing just that file to leave the repo surface clean.

The generated binary is gone; only the two intended Go files are modified. I’m doing one final status/diff check and then I’ll report the fixed findings and verification evidence.

SYSTEM NOTICE: Three review hazards entered. Three left in labeled bags.

Verification:

Rollback/traceability:

Ledger: tmp/pfleidi-review/review-cli-20260710-112423.md

No commits made.

Using receiving-code-review here: your feedback rejects the patch, so I’m reverting my changes first, then I’ll re-evaluate the findings instead of defending the first pass.

Reverting only my patch: the two Go files go back to the branch state, and the ignored review ledger I created gets removed. Then I’ll give a corrected assessment of what should and should not have been flagged.

The revert hit sandbox protection on the shared worktree index lock. Re-running the same surgical checkout with approval; this only resets the two files I touched.

Removing the ignored ledger artifact I created, then I’ll verify the worktree is back to the pre-fix branch diff.

Now checking status and the branch diff against origin/main so I can separate “reverted my patch” from “branch still has its intended worktree feature changes.”

The worktree is back to clean relative to the branch: git status --short produced no output, and git diff --stat produced no output. Branch diff against origin/main is again the original four-file feature diff.

Reverted my patch. Evidence:

Corrected review stance:

So the better report is: no Required findings. I should not have auto-fixed those. The first pass promoted speculative/intent-sensitive issues into merge blockers. Pathetic, but now contained.
