fix(repo): ws refresh crash-retry edges (temp sweep before .scignore, emptied directory) - #276
Conversation
…heck and replaces its own emptied directory (ref #275) A refresh that turns *.tmp from hidden to visible and is killed mid-write left a staging file the retry counted as an agent addition. The sweep now runs inside plan_checkout, before hidden_additions, for every path the result changes. A crash between the removal loop and the write loop of a dir/file -> dir replacement left an empty directory that refused the retry. On a retry an empty directory counts as the refresh's own when the candidate tracked files under it that the result drops; dir_clearable still refuses any content.

Explanation
Issue
#275has two coding requirements. The PR moves stale staging-file cleanup intoplan_checkoutbefore.scignorecomparison and limits cleanup to refresh-owned files from dead recorded writers. The PR also lets retry planning replace an empty directory left by completed tracked removals when the result now requires a file. The reported tests cover both cases and preserve refusal of user content. The source diff was unavailable, so this assessment relies on the supplied PR summary and test report.

- Around line 338-344: Update the ADR guarantee associated with plan_checkout to
state that refusal conditions are decided before the first checkout write, not
before every planning-side write. Document that retry cleanup via
sweep_stale_temps may remove stale staging files before a later hidden_additions
refusal and is intentional and not rolled back.

On a retry where the old .scignore hid *.tmp and the result exposes it, this pre-check sweep silently deletes any regular sibling named like b.<recorded-dead-pid>.<n>.tmp before hidden_additions can recognize it as a user file. The filename and dead PID are not proof of ownership: such an ignored file may have existed independently or been created after the crash, so retrying can lose user data instead of refusing as it previously did. Record the actual staging paths or otherwise verify ownership before removing them.

If the process dies after writing the pending marker but before removing dir/file, and the user then deletes or replaces that tracked subtree with their own empty dir (including one held as another process's working directory), this condition treats the directory as the refresh's husk solely because the candidate once contained a plain descendant. The retry consequently removes the user's directory even though the interrupted attempt never touched it, bypassing the fail-closed empty-directory guard. Track completed removals in the pending state or otherwise require evidence that the prior attempt actually emptied this directory.

Approved: independent code-reviewer (no blockers, findings fixed), Codex security clean, two narrow P2s deliberately documented, CI green. Separate possible issue filed (#278).
Closes #275
Two fail-closed crash-retry edges of
sc ws refresh(ADR-0056):<stem>.<pid>.<n>.tmp, recorded dead pids only, never through a symlinked parent) are now swept insideplan_checkoutbefore the.scignorecomparison, for every path the result changes. Before, a refresh that turned*.tmpfrom hidden to visible and died mid-write had its own temp file counted as an agent addition.dir_clearableandclear_dir_obstructionstill refuse any content, and a fresh refresh still refuses a user's empty directory.Tests (written first, both failed before the fix):
a_stale_staging_file_the_new_ignore_rules_expose_is_swept_before_they_are_compared,a_retry_replaces_the_empty_directory_its_own_removals_left(includes the user-content refusal). ADR-0056 text updated; the two edges were not in its known-limits paragraph, so there was nothing to remove there.Verified: fmt, clippy -D warnings,
