`untracked_files` read `ls-files --others` line by line and stripped each record. Under the default core.quotePath that yields git's C-quoted spelling of every non-ASCII (and newline-bearing) name and eats leading/trailing spaces, so `snapshot_worktree`'s `git add --` failed on a non-path, the rollback refused, and the cleanup plan got the wrong names. Now `ls-files -z` through `git_bytes` (the chokepoint's binary accessor): split on NUL, no strip, stderr never becomes a record (#442). Bytes rather than text mode because text mode's universal-newline read rewrites a `\r` in a name to `\n`. Decoding, as found: `_run_git` text mode decodes with the locale codec, strict, and translates UnicodeDecodeError into GitError (#377). But under the default quotePath git never emitted a raw high byte to this reader, so an invalid-UTF-8 name used to come back as its quoted token, not a GitError; only quotePath=false hosts got the GitError. Each record is now decoded strictly with the filesystem codec, and an undecodable one keeps the default-config answer (the quoted token, via `_c_quote_path`), which is inert and self-consistent across baseline and later reads. Raising instead would fail every baseline capture in a repo holding one such stray; surrogateescape would leak surrogates into state/journal JSON. Compatibility: a run persisted before this fix holds quoted/stripped records in `baseline_untracked`; an exact difference would make those pre-existing files deletion targets on resume. The rollback-side consumers (`snapshot_worktree`, `_rollback_cleanup_plan`, `attempt_dirty`) now go through `_created_untracked`, which also treats a path as baseline when any of its pre-fix spellings (git's quoting under either quotePath setting, split and stripped as the old reader did) is in the baseline. Spurious matches only spare a file. The proof-of-work gate keeps the exact difference: it fails open toward "work happened".
…teardown (#779) post_story fires after _run_isolated has merged the unit and removed its worktree, but the bus still chose ctx.worktree as the declarative hook's cwd. subprocess.run raised FileNotFoundError before the shell started, so the journal logged plugin-hook-error and the hook never ran. For post_story alone, a worktree that no longer exists falls back to ctx.repo_root. Every other stage keeps its cwd, and with it the error and fail-closed semantics, since the project root is the wrong tree mid-story. The context and BMAD_LOOP_WORKTREE keep the original path so a hook can still tell which unit it was. In-process Python hooks get no cwd from the bus and are unchanged.
…unt hook errors in diagnose (#783, #779) capture_diff still listed untracked files with the line-based `ls-files` read that #783 replaced in untracked_files. Under core.quotePath a non-ASCII name came back C-quoted (and `.strip()` ate edge spaces); `git diff --no-index` could not open that spelling and exited 1 with empty stdout, the code the loop tolerates as "the files differ", so the file was silently left out of the failed-unit forensic patch. The leg now iterates `sorted(untracked_files(repo))`, which also carries the #442 stdout-alone read. A name the filesystem codec cannot decode still arrives as the quoted token and stays omitted, the same residual #783 left. diagnose's plugin-errors total counted only `plugin-error`, so a run whose hook bus journaled `plugin-hook-error` summarized as 0 plugin errors beside a histogram showing plugin-hook-error=1. Both kinds now count.

- Around line 387-389: Update the isolated post_story hook documentation to
distinguish worktree states: when the worktree has been removed, the hook runs
from the repository root while BMAD_LOOP_WORKTREE retains its path; when it
still exists, the hook runs from that worktree.

Summary
untracked_filesused to readls-files --othersline by line and strip each record. Under the defaultcore.quotePaththat gave git's C-quoted spelling of every non-ASCII or newline-bearing name, and the strip removed leading and trailing spaces.snapshot_worktree'sgit add --then failed on a path that did not exist, the rollback refused, and the cleanup plan got the wrong names. The reader now usesls-files -zthroughgit_bytes, the chokepoint's binary accessor. It splits on NUL, strips nothing, and never turns stderr into a record (verify._gitmerges stderr into stdout for every caller, so a git that warns at rc 0 corrupts every output-reading probe #442). Each record is decoded strictly with the filesystem codec. A record that cannot be decoded keeps the quoted token, which matches what the default config returned before.baseline_untracked. The rollback-side consumers (snapshot_worktree,_rollback_cleanup_plan,attempt_dirty) now go through_created_untracked. It also counts a path as baseline when any of its pre-fix spellings is in the baseline, so resuming such a run does not delete pre-existing files. A spurious match can only spare a file. The proof-of-work gate keeps the exact difference and fails open toward "work happened".capture_diffreads the same way. It still listed untracked files with the line-based read. A quoted name madegit diff --no-indexexit 1 with empty stdout, which the loop accepts as "the files differ", so the file was silently left out of the failed-unit forensic patch. It now iteratessorted(untracked_files(repo)).post_storyhooks run from the repo root after worktree teardown.post_storyfires after_run_isolatedhas merged the unit and removed its worktree, but the bus still usedctx.worktreeas the declarative hook's cwd.subprocess.runraisedFileNotFoundErrorbefore the shell started, so the hook never ran and the journal recordedplugin-hook-error. Forpost_storyonly, a worktree that no longer exists now falls back toctx.repo_root. Every other stage keeps its cwd and its fail-closed behavior. The hook context andBMAD_LOOP_WORKTREEstill carry the original path.diagnosecounts hook errors. The plugin-errors total counted onlyplugin-error, so a run withplugin-hook-errorentries reported 0 plugin errors. Both kinds now count.Notes for reviewers
diagnose --jsonfieldplugin_error_countcan now report a higher value for the same journal, becauseplugin-hook-errorentries are included. The schema is unchanged.capture_diffstill leaves that file out, because--no-indexcannot open that spelling. untracked_files reads ls-files without -z, so a non-ASCII untracked path comes back C-quoted — the rollback safety-net snapshot then fails its own git add and halts the run #783 already left this case open. Raising on it would fail every baseline capture in a repo holding one such file.test_capture_diff_includes_verbatim_named_untracked, 4 params, andtest_summarize_journal_counts_plugin_hook_errors) were ablation-checked: they fail with the fix reverted.trunk checkclean.Stack
