When a project directory has been renamed, this rebases the context's spec path onto the live project, but the subsequent runs.rearm_escalation still loads the unchanged state.project/task.worktree_path and resolves task_spec_path against the old location. The interactive agent can therefore successfully edit the newly advertised file and write resolution.json, only for re-arm to report the spec missing or mutate a surviving old copy. Restamp or otherwise rebase the persisted project-owned anchors before constructing both the context and the re-arm target.

When policy changes from worktree to none, this now correctly reopens an accepted continuation in its recorded mount, but downstream cleanup still branches on live self._isolated. If that continuation later defers, Engine._defer skips the isolated _carry_harvested_deferrals path; integrate_unit then handles the task as failed and, with keep_failed = false, deletes the mount containing any gitignored harvested ledger entries. Use mounted-workspace semantics for the entire continuation, not only for choosing where it runs.

When another process closes a matched DW entry after _harvest_spec_deferrals reads its snapshot but before this locked update, _find_entry returns the now-done entry and this code still stamps it as seen again. The caller has already excluded the finding from pending, so no new open entry is filed and the recurrence is silently lost. Recheck entry.open inside the transaction and let the caller append the finding when the match became stale.

For every session without expected_spec—including stories-mode sessions and first sprint attempts—this scans every Markdown artifact and retains all marker fingerprints under a unique task ID for the adapter's entire lifetime. With N existing specs and M such sessions, the run performs and retains O(N×M) work, which can make large backlogs increasingly slow or memory-heavy. Scope the capture to the deterministic stories candidate where available, or evict each task's snapshot after its result is finalized.

This changes damping/exhaustion to journal the spent budget without filing a ledger entry, but docs/FEATURES.md:57 still promises that the lingering recommendation is re-filed for a later sweep. Operators following the repository's behavior reference will therefore look for work that is intentionally no longer created; update that documented contract or retain the advertised behavior.

On supported Python 3.11, Path.resolve() raises RuntimeError for a symlink loop, but this fallback catches only OSError. Consequently, a single looped *.md symlink in an artifact directory makes _capture_launch_auto_run_results abort before the transport starts, blocking every unpinned generic dev session instead of treating that unrelated marker as unreadable; catch RuntimeError here as the surrounding path-observation code does.

When a worktree task resumes after [scm] isolation changes to none and then defers, this branch correctly treats it as mounted, but _record_defer immediately calls _defer_recovery_note, whose line 6771 still selects solely on live self._isolated. If an earlier retry set preserve_ref, the notification therefore emits an in-place git -C <mounted-worktree> merge --ff-only ... command; integrate_unit subsequently deletes that directory when keep_failed = false, leaving the advertised recovery command unusable, and with keep_failed = true the notice also omits the branch holding the latest failed work. Make the recovery-note selector use the same mounted-task predicate as this defer path.

worktree list -z on the supported Git floor
On the documented minimum Git 2.34—Ubuntu 22.04's stock version—this command rejects -z; the Git 2.34 worktree synopsis only supports git worktree list [--porcelain]. Consequently, every isolated-task resume reaches worktree_is_registered(), gets a GitError, and escalates instead of reopening its recorded worktree, while orphan reconciliation silently skips cleanup. Either retain the newline parser on older supported Git or raise the declared Git floor to the version that introduced worktree list -z.

When a run is opened from a moved or copied project whose persisted state.project still names the old location, _review_escalation displays and validates the spec returned by _paused_spec, which remains anchored under that old project, while this argument makes rearm_escalation modify the copy under self.project. If the old tree is gone, the modal marks the spec unreadable and prevents the newly added moved-project re-arm path; if it still exists, the operator can review one spec and then re-arm a different, unreviewed copy. Rebase the TUI's displayed spec and confinement root using the same live-project mapping before enabling re-arm.

When an interrupted task changes from worktree isolation to in-place execution, _release_orphaned_mount deliberately leaves its old mount for recovery; if that same nonterminal task later changes back to worktree mode, this unconditional reclaim force-removes that directory before creating the replacement. Only commits unique to the old branch are preserved above, so any uncommitted files in the orphan are irreversibly lost—even with the default keep_failed = true—where the previous worktree add refusal left them intact. Capture the dirty work, move the orphan aside, or refuse the remount before calling discard_worktree.

When branch_per = "run" executes an isolated unit, switches to isolation = "none" long enough to commit another story on the target, and then switches back, branch_tip is the old shared-run tip while pinned_base is the now-advanced target. This arm remounts the old tip and ignores pinned_base, so the next session develops without the intervening in-place story; with merge_strategy = "ff" integration must then be refused because the target is no longer an ancestor, while other strategies may merge code that was developed against stale inputs. Bring the shared branch forward to the new base before remounting it.

For a stories-mode run opened after a project rename, this rebases only the spec text onto the live project; _story_context and _sentinel_kind still call task_stories_root, whose fallback is the recorded state.project. If the old tree is gone, the modal omits the story intent and the sentinel warning even though re-arm uses persisted sentinel_kind to delete the live sentinel; if the old tree remains, it can display stale intent from that copy. The fresh evidence after the earlier spec-anchor fix is this remaining split between the newly live spec and the modal's other story reads, which should use the same live-project mapping.

When an existing story branch is checked out in another registered worktree—for example, after an operator moves a retained recovery worktree—this update-ref-based reset succeeds and moves the branch underneath that checkout. The subsequent worktree add then fails because this call omits --force (Git’s help describes that option as “checkout even if already checked out in other worktree”), leaving the operator’s checkout with its index and files based on the old tip but its branch ref at pinned_base; even a previously clean checkout can suddenly appear modified. Detect branch occupancy and refuse before changing the ref.

When a persisted absolute spec uses a valid parent traversal, such as /old/project/../shared/spec.md resolving into a configured external artifact root, Path.relative_to() still returns ../shared/spec.md even though the canonical target is outside the recorded project. If the project is moved to a different parent, resolve and re-arm are redirected to /new/project/../shared/spec.md, so they can fail to reopen the actual shared spec or mutate an unrelated file there. Normalize or reject parent traversal before classifying the persisted path as project-owned.

When an isolated project's directory is renamed, the recorded mount no longer exists at its old spelling but may exist beneath the rebased project. This calls task_stories_root before rebasing, so that existence check discards the mount and returns the main project; the modal then reads its manifest and sentinel from the main checkout while live_spec_path and re-arm target the moved worktree. Fresh evidence after the prior TUI anchoring fix is that resolve._context_stories_root explicitly probes the rebased mount, while this shared helper does not; apply that ordering here as well.

When a run pauses at DEV_VERIFY in worktree mode and policy changes to none, this correctly reopens the recorded mount, but review recovery still branches on live self._isolated: _review_loop applies its in-place budget-exhaustion rescue and _salvage_review_timeout enables in-place timeout salvage. A mounted continuation can therefore commit a non-converged or timed-out review solely because of the policy flip, whereas the same mounted work under unchanged policy is deferred and preserved for later review. Fresh evidence beyond the previously reported defer-cleanup path is these two review-specific commit paths; make their isolation test include the recorded mount too.

When a re-arm targets a project that was renamed and a later operation fails after changing the live spec, this rebased spec_path is passed to _rollback_rearm, but _restore_rearmed_spec still derives its confinement root from the recorded state.project. The live path therefore appears outside that stale root and rollback falls back to the unconfined writer; if a live parent component is replaced with a symlink during this error window, the restoration follows it and can overwrite a file outside the project instead of refusing. Thread the corresponding live_spec_root through the rollback path as well.

When an operator moves a retained worktree to a valid POSIX path ending in whitespace, git for-each-ref emits that whitespace before its record newline, but _git_out applies .strip() to stdout. Consequently _refuse_foreign_checkout can mistake a foreign path such as <expected-mount> for <expected-mount>, exempt it as this unit's own mount, and then move the branch ref underneath the foreign checkout. Read this scalar without trimming path bytes, removing only Git's terminating newline.

The park-marker rows rewrite the spec and advance its mtime by one nanosecond above the launch capture. ext4 stores that; NTFS keeps ~100ns ticks, so on Windows the increment rounds away, the rewritten marker does not read as newer than the launch floor, the readback fails closed and `_result_json` returns None — nine rows asserting `rj is not None`. Bump by a whole second instead, which clears every granularity these tests can land on and matches the bump this file already uses elsewhere. The negative rows still distinguish what they did: the full file passes unchanged on a filesystem that did record the nanosecond.
…ice's rows The unreadable-artifact count added below this slice widens build_context to a triple; the rows added here still unpacked a pair.
…ry at the live tree Two sites where a persisted value stood in for the tree actually in hand. resolve: `build_context` publishes a `spec_file` rebased onto the LIVE CLI project, because `state.project` is the launch-time spelling and nothing re-stamps it — there is no project counterpart to `restamp_code_root`. `rearm_escalation` still resolved `task_spec_path` against the recorded project, so after a project move the agent edited one file and the re-arm flipped another; in the real shape the recorded tree is gone, the flip silently no-ops, and the re-drive wedges on the escalated attempt's status with the escalation spent. The rebase helper moves to `runs` (both sides need one answer, and `resolve` already imports it), and `rearm_escalation` takes the live project the way `build_context` does. Scope is the write target and its confinement root, which move together or the writers silently drop the confined arm. engine: `_finish_inflight` reopens a recorded mount regardless of live policy, but `_defer` gated `_carry_harvested_deferrals` on `self._isolated` alone. On a `worktree -> none` flip a deferring continuation reset the main repo, skipped the carry, and lost the unit's harvested findings when `_integrate_unit` deleted the mount. The gate is now the same pair `_run_story` already uses.
…es stale `_harvest_spec_deferrals` decides the cross-spec dedupe against a ledger SNAPSHOT and excludes the matched finding from its append on the strength of that match, then stamps the sighting later, under `mark_seen_again_many`'s lock. A rival that closed or archived the entry in that window left `_find_entry` returning a done entry, which the mark stamped anyway — so the sighting landed on a closed row, no open entry was filed, and the recurrence was recorded nowhere. `mark_seen_again_many` now rechecks `entry.open` inside the hold and returns the ids whose match went stale alongside the applied flags and the published text. The two ways a flag can be False are no longer interchangeable: a replay whose line is already present has a live sighting and must file nothing, while a missing or no-longer-open id has none. `entry.open` deliberately, not `not entry.done` — an unparseable status is neither, and the question is only whether this is still the open entry the caller matched. The harvest folds the stale ids' findings back into both the append and `harvested_deferrals` (records ahead of the write that files them, as before, so the isolation carry can re-file them), narrows `seen_again` to the entries that actually took a sighting, and journals `spec-deferral-sighting-stale`. The row builder and the record absorption are shared by both passes so the recovered rows are byte-identical to the ones the snapshot scan would have filed.
The bounded-review-loop bullet promised that when the follow-up-review damping cap is spent the lingering recommendation "is re-filed to the deferred-work ledger". `_journal_review_budget_spent` does the opposite by design: it journals the spent budget (`review-followup-damped`, or `review-budget-committed` on plain exhaustion) and files nothing, because the DW-55/64/90 class showed such rows re-litigate a converged story's review rather than record work anyone chose to defer. FEATURES.md is a behavior contract, so state what ships. The one path that still files is the review TIMEOUT salvage, under its own `review-timeout-salvage` origin — named here so the correction cannot be read as "the orchestrator never re-files a follow-up".
…uilder `_marker_path_key` wrapped `Path.resolve()` in `except OSError:`, but on the 3.11 support floor a symlink loop raises `RuntimeError` — not an OSError — and on 3.13 it raises nothing at all. So the fallback was inert on the floor and unreachable on the dev interpreter: one looped `*.md` under an artifact dir aborted `_capture_launch_auto_run_results` before the transport started, and with it every unpinned generic dev session, which globs the whole directory. Catch `(OSError, RuntimeError)`, the shape every other `resolve()` guard in the package already uses. The loop entry then reads as one unreadable marker (`read_text` raises ELOOP on every interpreter) and the readable spec beside it is still captured. Two tests: the unit row injects the RuntimeError through a Path subclass so it means the same thing on every interpreter CI runs; the launch row builds a real `a -> b -> a` loop and is non-vacuous on 3.11 only, for the reason above.
…r as the defer `_defer` routes on `self._isolated or task.worktree_path`, but the recovery note `_record_defer` emits two lines later still selected on live isolation alone. A run flipped `"worktree" -> "none"` while paused therefore reached the defer with the workspace swapped onto its mount and printed the in-place `git -C <mount> merge --ff-only <ref>` — aimed at a directory `_integrate_unit` deletes on the way out with `keep_failed` off — and with it on, omitted the branch holding the latest failed work. `preserve_ref` is set on that path whenever an earlier in-worktree dev-retry rollback parked one (#333: the ref is not isolation-scoped), so both facts are live at once. The selector now uses the same pair. The isolated arm's rule is unchanged: name the ref, never offer a fast-forward that would land a discarded attempt.
…rse on the floor The isolation-flip sweep replaced the newline-delimited `worktree list --porcelain` parse with `-z`, a switch git added in 2.36. The 2.34 support floor — Ubuntu 22.04's stock 2.34.1 — rejects it outright (`error: unknown switch `z'`, exit 129, measured in an ubuntu:22.04 container), so on the floor every isolated-task resume reached `worktree_is_registered`, got a `GitError`, and escalated instead of reopening its recorded mount, while orphan reconciliation silently skipped its cleanup. The floor is documented as a support floor, not a capability one: no command bmad-loop issues may need more. `worktree_list` now asks `git_below_floor` for 2.36 and issues `-z` only where git offers it; below that — or when git will not say what it is — the parse the floor supports is used, and the one shape it cannot represent (a newline inside a worktree path) reads as a truncated record for that entry alone.
…arm writes `_do_rearm` hands `rearm_escalation` `project_root=self.project`, so after a project move the re-arm flips the spec under the live tree — while `_paused_spec` and `_paused_spec_root` still anchored on the recorded `state.project`. Opened from a moved project, the modal showed the old tree's copy: unreadable once that tree was gone, which refused the very re-arm the live mapping exists for; and with both trees present, the operator reviewed one spec and re-armed a different, unreviewed one. Both anchors now go through the mapping the re-arm uses. `_live_spec_path` and `_live_spec_root` are promoted to public `live_spec_path` / `live_spec_root` rather than re-derived in the TUI, because the read and write sides of one gesture must produce the identical path. The no-task arm of the root moves with them — it is the same mapping applied to the recorded project, which lands on `self.project`, so the two arms keep making one claim.
…rm writes `_story_context` and `_sentinel_kind` anchored on `runs.task_stories_root`, whose no-mount arm is the recorded `state.project`, while `_paused_spec` already reads through the live mapping the re-arm writes. After a project move the modal showed the live spec beside a title, description and sentinel indicator from the old tree — omitted once it was gone, stale while it lingered. Add `runs.live_stories_root` beside `live_spec_root` and use it in both readers. A mount sits outside the recorded project, so the rebase passes it through and the isolated arm keeps its answer; only the project fallback moves.
…remount reclaims its path
…lls back `live_stories_root` called `task_stories_root` first, which decides between the mount and the project on an existence probe against the RECORDED spelling. `RUNS_DIR` is `.bmad-loop/runs`, so a mount lives inside the project and rebases with a rename; its recorded spelling is then gone, the probe fails, the mount is discarded, and rebasing the project fallback answers the main checkout — while `live_spec_path` (no probe in `task_spec_root`) follows the rename onto the moved mount. The escalation modal read title, description and sentinel from the stale twin while `blocking` and the re-arm targeted the moved worktree. Adopt `_context_stories_root`'s ordering, and make that function delegate here so one definition serves `context.json` and the TUI. Correct the mirrored claim in both docstring and `tui.app` that a mount lies outside the recorded project.
…k pair as the defer
`_restore_rearmed_spec` derived its `confine_root` from `task_spec_root`, the recorded project spelling that nothing re-stamps, while the three forward writers it undoes — the status flip, the `## Auto Run Result` strip and the baseline re-stamp — all confine against `live_spec_root`, and the path it writes is itself `live_spec_path`. The arm predicate is a lexical `is_relative_to`, so after an isolated project rename the live path is not under the stale root, the predicate goes False, and the rollback silently takes the unconfined `atomic_write_bytes` arm on exactly the specs its siblings had just written through the confined one. Without an attacker the outcome is indistinguishable — right file, right bytes, `rollback='restored'` — which is why nothing downstream caught it; what is lost is #593's O_NOFOLLOW walk of the PARENT components, since `follow_symlinks=False` guards only the final one. Thread the live project root through `rearm_escalation` -> `_rollback_rearm` -> `_restore_rearmed_spec` as a REQUIRED parameter: an optional one falling back to `task_spec_root` would reintroduce the same silent degradation. The two-arm structure and `require_writable_target=True` on both arms are unchanged — only the root the predicate compares against is corrected. The dimension was wholly uncovered: every existing row calls `rearm_escalation` without `project_root`, so the two roots were the same string and each stayed green either way. The new row supplies a differing `project_root` and spies both writers on the `runs` namespace the call site reads them from.
`branch_checkout_path` read `for-each-ref --format=%(worktreepath)` through
`_git_out`, which returns `stdout.strip()`. A foreign checkout registered at a
unit's own deterministic mount path plus a trailing space therefore came back as
the bare mount path, compared EQUAL to it in `_refuse_foreign_checkout`, and was
exempted as if it were this unit's own orphan. The ref then moved under a live
foreign checkout, its tree went spuriously dirty, and `worktree add` failed on the
held branch anyway — exactly the harm the occupancy guard was added to prevent,
with the guard present. The function's own docstring already promised the opposite
("git's registered spelling, un-canonicalized").
Scoped to the call site. `_git_out` is untouched: it has 16 other callers and at
least two would change behavior — `untracked_files` and the `status --porcelain`
read in `commit_paths`, whose records legitimately begin with a space. `_git_raw`
drops the diagnostic, so a failure message would lose stderr. A new `_git_raw_out`
beside it returns `(rc, stdout VERBATIM, merged detail)`, and only the single
framing `\n` is removed — an empty answer still means "no worktree has it
attached" and returns None.
The error could only go the unsafe way: `safe_segment` rstrips ". " from every
segment we compose, so our own mount path can never end in whitespace and a
spurious REFUSE is unreachable. The negative control pins that half and is ablated
twice, since "does not raise" passes for every reason.
Accepted bound, documented at the reader: `_run_git` uses `text=True` (universal
newlines), so a path ending in `\r` stays indistinguishable even after this fix.
… unit The pre-dispatch guard in `run_isolated` asked only `_is_file(unit.path / task.spec_file)`. That helper folds OSError to False around `Path.is_file()`, which FOLLOWS symlinks and answers only "are there readable bytes here" — it carries no containment check at all. `_accepted_spec_seed` already refuses a destination that resolves outside the mount, but it refuses SILENTLY: the rel never reaches `seed_files`, so neither `worktree-seed-skipped` nor `worktree-seed-dropped` names it, leaving this probe as the only remaining guard. When the accepted spec's parent is a real directory in the main checkout but a committed OUTWARD symlink in the commit the mount is cut from, the probe follows that link to an unrelated external artifact, answers true, and the unit dispatches reading someone else's bytes under the accepted spec's name. The regular-file half was already correct; only containment was missing. Resolve the probe once and require it to stay under the mount, folding OSError / RuntimeError / ValueError to "not delivered" so an unresolvable probe escalates rather than binds. A legitimate INWARD link whose target is inside the mount still passes, because resolve() lands it back under the unit root. Regression test builds the real shape — committed outward symlink materialized in the fresh worktree over an external file — and is POSIX-only, matching the neighbouring symlink tests. Ablated twice: removing the containment clause and removing the whole condition each turn it red.
… beat the lock Both locked mutators hand back the WHOLE post-edit file, so an entry a rival appended between this task's pre-harvest snapshot and the mutator's locked read was re-published under the run's name and landed in post_engine_ledger_digest. A later rejected attempt then read _restore_ledger's compare-and-set as owned and whole-file-overwrote with the old snapshot, deleting the rival's entry in silence — the default ledger is gitignored, so the digest is the sole write authorization and git never republishes it. mark_seen_again_many and append_entries_published now also return the preimage they read under the lock. Both engine anchor sites re-anchor only when that preimage is still the bytes the run last claimed; otherwise the anchor stays on the snapshot, the restore sees ours as False, and it journals the existing ledger-restore-skipped-diverged kind. The comparison is against the anchor rather than task.pre_harvest_ledger because the harvest's mark leg legitimately moves the anchor before its append leg runs, so the append's preimage is the mark's published text.
… the reclaim An orphan-mount reclaim drew its snapshot candidates from `untracked_files`, i.e. `git ls-files --others --exclude-standard`, which excludes ignored paths by contract. The deferred-work ledger, the sprint board and the bound spec are ignored inside every mount by construction: WorktreeFlow seeds them into a tracked-only checkout and folds every seeded rel into the worktree-local info/exclude. The mount therefore held the only copy, and the reclaim's `worktree_remove(force=True)` deleted it — silently over a clean tracked tree, where the snapshot returned None so there was no ref, no on_orphan_preserved callback and no journal line. An orphan never merges, so no carry and no replay handle survived either. `_orphan_owned_rels` derives those three rels from the `paths` argument the open already receives, rebased onto the mount, and includes each only when the mount holds it as a regular file; they ride `snapshot_worktree`'s existing `force_include`. `ProjectPaths` carries no spec member, so the accepted spec's spelling is threaded in as a new keyword-only `spec_file` and resolved against the rebased paths. Candidates are judged one at a time. An artifacts dir configured outside the project tree is supported, and `rebased` leaves it unmoved there, so the ledger and board resolve outside the mount and correctly drop — they are shared, not per-checkout. The spec must not drop with them: `_accepted_spec_seed` lays it inside the mount regardless, where it is still the only copy. A single `try` around the loop voided all three the moment the first raised, which would have made this inert in exactly that configuration. `is_file()` re-raising EACCES through 3.13 has the same shape and is contained the same way. Naming still degrades to `()` on a setup fault, in `_ledger_seed`'s style; the #340 gate stays at the capture, where a named rel git cannot stage refuses the remount. Deliberately narrow. Preserving every ignored path would park the seeded `_bmad/` tree, the adapters' MCP configs and venv residue into a ref `scm.preserve_keep` retains 20 deep; refusing the reclaim would break the flip-back path outright, since every mount has shielded ignored files.

Annotate escalate_unit as NoReturn
WorktreeFlow._pause is typed as Callable[..., NoReturn], so neither handler can return at runtime. However, escalate_unit is declared as returning None, so Pyright can report mounted and mounted_branch as possibly unbound. Change escalate_unit to return NoReturn; a bare return would violate reopen_unit’s UnitWorkspace return type.

Skip this row when git predates the -z switch.
test_worktree_list_preserves_newlines_in_paths does not stub git_below_floor, so it exercises the live host's git. The NUL-delimited parse only runs when git satisfies _WORKTREE_LIST_NUL_GIT (2.36). On a host at the declared 2.34 support floor, worktree_list takes the newline parse, truncates the record for that path, and both assertions fail. The sibling test above documents 2.34.1 as a supported version, so this row can redden on a supported host rather than skip.
Gate the row on the same version probe the production code uses.

What
Third of five stacked PRs draining Wave 2's deferred-work ledger. Closes DW-14 … DW-18, DW-33,
DW-35, DW-36, DW-41 … DW-51 (19 entries): the resolve session root context, the spec path
resolvers, the isolation flip's mount state, and the session-authored park assertions.
Why
Wave 2 anchored the baseline contract on one tree; the review then found the surrounding readers
still deriving their own roots and the park assertions unable to tell a session-authored marker
from any other. These are the entries that make the "one tree, one reader" claim hold at the
edges rather than only at the centre.
How
bmad-loop resolvecarries a session root context (DW-14, DW-35) and the spec pathresolvers are documented and shared (DW-17, DW-18, DW-36).
marker's author is established rather than assumed.
(DW-43, DW-44).
(DW-51); atomic TUI replan (DW-33); dead artifact relpaths removed (DW-15); the task generation
suffix peeled (DW-16).
Testing
uv run pytest -q -n logical,uv run pyright, andtrunk check --all --no-fixall clean atthis tip. Negative assertions ablated before being trusted.
