- `main` is always the stable release; README curl install pins `main` (not version tags). Do not describe `main` as a development/moving target.
- `clean` supports `--gone` and `--merged` (detecting direct, rebased, and squash-merged PRs); `--older-than` is omitted.
- When resolving CodeRabbit review comments, verify each claim against the code before acting; report skipped findings with the reason rather than silently dropping them.
- The Homebrew workflow owns the formula's `url`/`sha256` pair — it rewrites both together after a release is published. Do not hand-bump either: the tag's tarball sha cannot be computed before the tag exists, so editing the url alone ships a checksum mismatch.
- Verify a review finding before acting on it *and* before rejecting it; CodeRabbit's 1.0.3 pass included a false claim that the smoke suite was broken (CI was green on both platforms) alongside three findings that were real.

Fail the checksum step when curl fails.

This pipeline does not enable pipefail. If curl fails, sha256sum hashes empty input and the workflow can commit and publish that checksum. Enable pipefail before the pipeline so the formula remains unchanged on a download failure.

scripting `clean` depends on it.



**`sync` fetches once for the whole container.** Every worktree shares one
object store, so a per-worktree fetch transfers nothing after the first — the
single fetch is the design, not an optimisation to unroll. The default strategy
is `--ff-only`; `--rebase` is opt-in, and a strategy without `--pull` is
rejected rather than silently ignored, since `sync --rebase` that only fetched
would look like it had rebased. Like `clean`, the loop runs to completion and
returns nonzero if any worktree was skipped, so a nonzero exit means partial
success, not a stop. A detached HEAD is reported but deliberately not counted
as a failure.

**`_sync_target` gates on worktree registration too**, but for a different
reason than `cmd_rm`'s: not to keep `TREES_RM_CMD` away from the container
root — `sync` never removes anything — but because an existing directory git
does not know as a worktree would otherwise resolve to a real path, match
nothing in the pull loop, and exit 0 having done nothing. A silent no-op is
worse than an error, so the unregistered case must keep reporting `is not a

## Git pitfall: a start-point can override `-b`

`git worktree add --no-track -b <new> <dir> <base>` does **not** guarantee a
worktree on `<new>`. When `<base>` is a bare name matching a branch that exists
only on the remote, git's DWIM reads it as "create a local branch tracking
`origin/<base>`" and overrides `-b <new>` entirely: the worktree comes up on
`<base>`, `<new>` is never created, a stray local `<base>` ref is left to go
stale, and the exit status is 0. `--no-track` does not help — it governs the
upstream, not the branch name.

`cmd_add` resolves the base through `_base_sha` first (local commit-ish, else
`origin/<base>`) and passes the sha, which leaves nothing for the DWIM to latch
onto, and then asserts the new worktree's `HEAD` really is `<br>`. Keep both:
the resolution is the fix, the assertion is what makes a future regression loud.
