Problem
runtime_recovery_guard._SEGMENT_SPLIT_RE splits a compound command line so each simple command is classified on its own. The background-job separator & was missing from the alternation and a subshell wrapper ( ... ) was never stripped before tokenising, so _analyse_kill_segment — which inspects only the first command token of a segment — never reached the kill verb in either form. With no marker written, review, merge, close and completion mutations stayed reachable after a real daemon kill.
Adding & to a quote-unaware splitter, as the first head did, fixed those two forms but created a false-positive class. Review #497 measured three regressions against base 35e94e10, all of which merely mention the canonical kill string:
A false contamination marker fails review, merge, close and completion mutations closed and by design only a reconciler may clear it, so it is an operator-visible stall rather than a warning. Since the regressing string is the exact example this issue is written around, a doc line or commit message about #787 was itself a trigger.
Implementation
The alternation is replaced by a quote-aware scan. _iter_active() yields only the character positions where a shell metacharacter is syntactically active — outside single and double quotes, and not backslash-escaped — and _split_segments() separates only at those positions. This addresses the class, not the three named strings, and also retires the ; and | false positives that predate this issue.
&& and || are still consumed whole, so logical-separator precedence and the behaviour of ;, |, newlines and standalone & are unchanged.
_strip_subshell() removes a trailing ) only when it closes a leading ( that the same call stripped, so balanced command substitution survives (kill $(pgrep -f myapp) is no longer mangled into kill $(pgrep -f myapp).
_is_redirection() keeps 2>&1, >&2 and &>log from being read as background separators; a 2>&1 previously split into ['a 2>', '1'].
The last two are the reviewer's informational F3 observations. Neither changed a verdict at the rejected head, and neither is required to close#787 on its own; they are corrected here only because F1 required reworking the same splitter, which is where the reviewer asked for them to be tightened or commented.
Out of scope and untouched, as the issue directs: the contamination model, the gated-task set, the marker lifecycle, and the reconciler-only clearing path. No widening of detection to automatic ingestion from other tools.

## Head
`aa4fe1cc7bd2d6f07ea35775a5c5292d94a938e0`
Base parent chain: `35e94e107c32cfdc4b9ab9a95cb4e94df94077d4` (current master) -> `6b58f04d396b881d5d242eacac45bcfdfefe2d00` (the head review #497 rejected) -> `aa4fe1cc` (this remediation).
## Problem
`runtime_recovery_guard._SEGMENT_SPLIT_RE` splits a compound command line so each simple command is classified on its own. The background-job separator `&` was missing from the alternation and a subshell wrapper `( ... )` was never stripped before tokenising, so `_analyse_kill_segment` — which inspects only the first command token of a segment — never reached the kill verb in either form. With no marker written, review, merge, close and completion mutations stayed reachable after a real daemon kill.
Adding `&` to a **quote-unaware** splitter, as the first head did, fixed those two forms but created a false-positive class. Review #497 measured three regressions against base `35e94e10`, all of which merely *mention* the canonical kill string:
```
git commit -m "block sleep 1 & pkill -f mcp_server.py as recovery"
echo "docs: sleep 1 & pkill -f mcp_server.py is now detected"
grep -rn "sleep 1 & pkill -f mcp_server.py" docs/
```
A false contamination marker fails review, merge, close and completion mutations closed and by design only a reconciler may clear it, so it is an operator-visible stall rather than a warning. Since the regressing string is the exact example this issue is written around, a doc line or commit message about #787 was itself a trigger.
## Implementation
- The alternation is replaced by a quote-aware scan. `_iter_active()` yields only the character positions where a shell metacharacter is syntactically active — outside single and double quotes, and not backslash-escaped — and `_split_segments()` separates only at those positions. This addresses the class, not the three named strings, and also retires the `;` and `|` false positives that predate this issue.
- `&&` and `||` are still consumed whole, so logical-separator precedence and the behaviour of `;`, `|`, newlines and standalone `&` are unchanged.
- `_strip_subshell()` removes a trailing `)` only when it closes a leading `(` that the same call stripped, so balanced command substitution survives (`kill $(pgrep -f myapp)` is no longer mangled into `kill $(pgrep -f myapp`).
- `_is_redirection()` keeps `2>&1`, `>&2` and `&>log` from being read as background separators; `a 2>&1` previously split into `['a 2>', '1']`.
The last two are the reviewer's informational F3 observations.

Author role stops here. This PR needs a fresh reviewer; the author has not reviewed, approved, or merged it.
`runtime_recovery_guard._SEGMENT_SPLIT_RE` claimed to split a compound command
line "on shell separators", but omitted the background-job separator `&`, and no
caller stripped a subshell wrapper before tokenising. `_analyse_kill_segment`
only inspects the first command token of a segment, so in both forms the kill
verb never reached the classifier.
Measured against the previous implementation at 35e94e10:
sleep 1 & pkill -f mcp_server.py -> process_kill False, contamination False
(pkill -f mcp_server.py) -> process_kill False, contamination False
Changes:
- Add `&` to `_SEGMENT_SPLIT_RE` as `(?:\|\||&&|[|;&\n])`; the two-character
logical forms stay first so `&&` and `||` are consumed whole.
- Add `_strip_subshell()` and apply it in `_split_segments()`, removing leading
`(` and trailing `)` (including nested wrappers) before tokenising.
Both forms now classify as contamination with reason class `manual_daemon_kill`,
and the record tool writes a durable marker for each. Direct-command behaviour is
unchanged. The contamination model, gated-task set, marker lifecycle, and
reconciler-only clearing path are untouched.

Scope examined
Diff versus base master 35e94e107c32cfdc4b9ab9a95cb4e94df94077d4 touches exactly two files, 103 insertions, 3 deletions:
runtime_recovery_guard.py — _SEGMENT_SPLIT_RE widened, new _strip_subshell(), applied in _split_segments().
tests/test_issue_630_runtime_recovery_guard.py — new cases only.
No unrelated refactoring. The contamination model, gated-task set, marker lifecycle, and reconciler-only clearing path are untouched. Scope discipline for #787 holds.
Behaviour was examined by reading the diff at the pinned head in a dedicated detached worktree, by direct in-process classification of 28 command strings against both the head and a clean-base copy of the guard, and by running the test suites at both commits.
What is correct
Both previously missed forms are genuinely fixed. Reproduced independently at the pinned head:
Same two strings against the clean-base copy of the guard reproduce the defect exactly as issue #787 records it (contamination=False, reason_class=None), so the change is the cause of the improvement.
Operator precedence survives the widened alternation. _split_segments returns ['a', 'b', 'c'] for a && b || c and ['a', 'b'] for a & b; true && false || pkill -f mcp_server.py still classifies as contamination and systemctl restart myapp && echo ok does not.
Existing direct-command behaviour is preserved: pkill -f mcp_server.py, pkill -f gitea_mcp_server, killall mcp_server, sudo pkill -f mcp_server.py, the && compound, and the broad pkill -f python sweep all keep their prior outcomes. pkill -u mcpuser -f myapp stays non-contaminating and unambiguous, ps aux | grep mcp_server stays a non-kill, kill 31337 stays ambiguous and non-contaminating, and benign background jobs (npm run dev & sleep 2) are not flagged.
The broader-failure claim is sound. Verified at both commits in separate worktrees, not taken on trust.
Findings
F1 — BLOCKING (correctness + coverage). Splitting on & creates a new false-positive class, and the one test that guards it is written so it cannot catch the case.
The splitter is quote-unaware. Adding & therefore makes any quoted text containing an ampersand followed by a kill verb classify as contamination. Measured, head versus clean base:
command base head
git commit -m "block sleep 1 & pkill -f mcp_server.py as recovery" False True <-- NEW
echo "docs: sleep 1 & pkill -f mcp_server.py is now detected" False True <-- NEW
grep -rn "sleep 1 & pkill -f mcp_server.py" docs/ False True <-- NEW
git commit -m "fix; pkill -f mcp_server.py" True True (pre-existing)
git commit -m "fix | pkill -f mcp_server.py" True True (pre-existing)
Three of these are regressions introduced by this head. The ; and | rows show the underlying quote-unawareness predates this PR, so the class is not new — but this change extends it to the one separator that appears in the canonical example string, and that string is the subject of this very issue. Any commit message, doc line, or grep that quotes sleep 1 & pkill -f mcp_server.py now classifies as a manual daemon kill.
Why this is blocking rather than cosmetic: issue #787 scope item 4 names "a commit message quoting the kill string" as a case that must keep its non-contaminating outcome, and AC5 requires test coverage for it. The PR adds test_commit_message_quoting_the_kill_string_is_not_a_kill, but the string it quotes omits the ampersand, so the test passes while the very form the issue is about regresses. The named case is nominally covered and actually unprotected.
Consequence when triggered: gitea_record_daemon_process_kill_attempt writes a durable contamination marker, and _enforce_runtime_recovery_contamination_gate then fails review, merge, close and completion mutations closed. By design a worker session cannot clear it — only a reconciler can. A false marker is therefore an operator-visible stall, not a warning.
Blast radius today is bounded: assess_recovery_command has exactly one production consumer, gitea_record_daemon_process_kill_attempt, so the marker is written only when a session explicitly calls that tool. It is not yet wired to arbitrary command strings. That containment is exactly what the issue's own deferred follow-up proposes to remove by feeding the classifier from gitea_record_pre_review_command and gitea_assess_gitea_operation_path. Landing this false-positive surface first and that wiring later would turn a latent defect into a live one.
Required change, either of:
Preferred — make segment splitting quote-aware: walk the string tracking single/double-quote state and split only on separators found outside quotes. Roughly ten lines, no change to the classifier, and it also removes the two pre-existing ; and | false positives, so the guard strictly improves.
Minimum — keep the current splitter but add the ampersand-bearing form of the commit-message case to the no-false-positive tests and make it pass.
Either way AC5 needs a case that quotes the full sleep 1 & pkill -f mcp_server.py string inside a non-executing command and asserts contamination is False.
F2 — MINOR (evidence accuracy). The stated test counts in the PR body do not match the head.
The body states the file "held 46 cases before this change" and that "9 were added". Counted at both commits, and confirmed by collection: base 35e94e10 47 passed, head 6b58f04 55 passed. Eight test functions are added, not nine, and the prior count was 47, not 46. The suites themselves pass as claimed; only the arithmetic in the narrative is wrong. Please correct the body so the record is accurate.
F3 — INFORMATIONAL. _strip_subshell and the widened split both treat shell syntax loosely.
_strip_subshell removes a trailing ) unconditionally, so kill $(pgrep -f myapp) becomes kill $(pgrep -f myapp. No classification changes today because the remaining text still carries or lacks the daemon pattern, but the helper mangles balanced command substitution as a side effect of stripping an unbalanced wrapper. Similarly the new & split turns a 2>&1 into ['a 2>', '1']. Neither causes a wrong verdict in the cases tested; both are worth a comment or a tightened implementation if the splitter is reworked for F1.

AC4 (marker written for both new forms) is covered by the two new record-tool cases, which pass in the focused run above. This reviewer did not invoke the live record tool, because writing a real contamination marker would fail this session's own review mutation closed.
Verdict rationale
AC1, AC2 and AC4 are met. AC3 is met for the cases the issue enumerates literally. AC5 is not met: the commit-message case it names is covered only in a form that cannot exercise the new code path, and the head regresses that case for the exact string the issue is about. F1 is a correctness defect in the shipped behaviour, so the verdict is request_changes.
[THREAD STATE LEDGER] PR #789 — reviewer verdict request_changes at head 6b58f04
What is true now:
Server-side decision state: a REQUEST_CHANGES review verdict is being recorded against head 6b58f04d396b881d5d242eacac45bcfdfefe2d00; no merge event has occurred; PR #789 remains in open state; issue #787 remains in open state.
Local verdict/state: independent review complete at the pinned head; one blocking finding (F1), one minor evidence finding (F2), one informational finding (F3).
Latest known validation: focused suite 55 passed at head and 47 passed at base; the five broader modules produce an identical 11-failure signature at both commits.
What changed:
A reviewer verdict of request_changes is recorded for head 6b58f04d396b881d5d242eacac45bcfdfefe2d00.
No branch, lock, lease, or repository content was altered by this review.
What is blocked:
Blocker classification: code blocker
F1: splitting on & introduces three measured false positives on quoted text containing an ampersand and a kill verb, and the AC5 test for the commit-message case omits the ampersand so it cannot catch them.
Who/what acts next:

Required action: implement F1 (preferably quote-aware segment splitting), add an AC5 case quoting the full sleep 1 & pkill -f mcp_server.py string inside a non-executing command asserting contamination False, correct the test-count arithmetic in the PR body for F2, and push a new head for re-review.
Do not do: do not merge this head; do not treat the focused suite passing as evidence that the commit-message case is protected; do not widen the classifier into other tools while F1 stands.

F1 (blocking): _SEGMENT_SPLIT_RE is quote-unaware, so adding `&` made quoted
text containing an ampersand plus a kill verb classify as contamination.
Measured regressions versus base 35e94e10:
git commit -m "block sleep 1 & pkill -f mcp_server.py as recovery"
echo "docs: sleep 1 & pkill -f mcp_server.py is now detected"
grep -rn "sleep 1 & pkill -f mcp_server.py" docs/
Preferred fix: split only on separators found outside single/double quotes.
This also removes the pre-existing `;` and `|` false positives.
F1 coverage: test_commit_message_quoting_the_kill_string_is_not_a_kill quotes a
string without an ampersand, so it cannot catch the regression. Add a case
quoting the full `sleep 1 & pkill -f mcp_server.py` string inside a
non-executing command and assert contamination is False.
F2 (minor): the PR body says the file held 46 cases and 9 were added. Measured:
47 at base, 55 at head, so 8 were added. Correct the body.
F3 (informational): _strip_subshell strips a trailing `)` unconditionally, and
the new split turns `a 2>&1` into ['a 2>', '1']. Tighten or comment if the
splitter is reworked.
Keep the scope to issue #787. Re-run the focused suite plus the five broader
modules at base and at the new head, then hand off to a fresh reviewer.
WHAT_HAPPENED:
An independent reviewer examined PR #789 at head 6b58f04d39 in a dedicated detached worktree, read the two-file diff, classified 28 command strings against both the head and a clean-base copy of the guard, and ran the focused suite and five broader modules at both commits. Both forms named in issue #787 are correctly detected and operator precedence is preserved, but splitting on & introduced three measured false positives on quoted text, and the AC5 test that should protect the commit-message case omits the ampersand.
WHY:
A false contamination marker fails review, merge, close and completion mutations closed and can only be cleared by a reconciler, so a false positive is an operator-visible stall. The regressing string is the exact example the issue is written around, which makes a documentation or commit-message mention of #787 a trigger.
BLOCKERS:
F1 — quote-unaware splitting on & yields three measured false positives at this head; the AC5 commit-message test cannot catch them because it omits the ampersand.
VALIDATION:
Focused suite 55 passed at head 6b58f04, 47 passed at base 35e94e10. Five broader modules give an identical 11-failure signature at both commits (11 failed, 254 passed), confirming those failures predate the branch. Classification of 28 command strings run against head and clean base; both issue forms reproduce as contamination at head and as non-detection at base; three quoted-text regressions measured at head only.

## Scope examined
Diff versus base master `35e94e107c32cfdc4b9ab9a95cb4e94df94077d4` touches exactly two files, 103 insertions, 3 deletions:
- `runtime_recovery_guard.py` — `_SEGMENT_SPLIT_RE` widened, new `_strip_subshell()`, applied in `_split_segments()`.
- `tests/test_issue_630_runtime_recovery_guard.py` — new cases only.
No unrelated refactoring. The contamination model, gated-task set, marker lifecycle, and reconciler-only clearing path are untouched. Scope discipline for #787 holds.
Behaviour was examined by reading the diff at the pinned head in a dedicated detached worktree, by direct in-process classification of 28 command strings against both the head and a clean-base copy of the guard, and by running the test suites at both commits.
## What is correct
Both previously missed forms are genuinely fixed. Reproduced independently at the pinned head:
```
sleep 1 & pkill -f mcp_server.py contamination=True reason_class=manual_daemon_kill ambiguous=False
(pkill -f mcp_server.py) contamination=True reason_class=manual_daemon_kill ambiguous=False
```
Same two strings against the clean-base copy of the guard reproduce the defect exactly as issue #787 records it (contamination=False, reason_class=None), so the change is the cause of the improvement.
Operator precedence survives the widened alternation. `_split_segments` returns `['a', 'b', 'c']` for `a && b || c` and `['a', 'b']` for `a & b`; `true && false || pkill -f mcp_server.py` still classifies as contamination and `systemctl restart myapp && echo ok` does not.
Existing direct-command behaviour is preserved: `pkill -f mcp_server.py`, `pkill -f gitea_mcp_server`, `killall mcp_server`, `sudo pkill -f mcp_server.py`, the `&&` compound, and the broad `pkill -f python` sweep all keep their prior outcomes. `pkill -u mcpuser -f myapp` stays non-contaminating and unambiguous, `ps aux | grep mcp_server` stays a non-kill, `kill 31337` stays ambiguous and non-contaminating, and benign background jobs (`npm run dev & sleep 2`) are not flagged.
The broader-failure claim is sound. Verified at both commits in separate worktrees, not taken on trust.
## Findings
### F1 — BLOCKING (correctness + coverage). Splitting on `&` creates a new false-positive class, and the one test that guards it is written so it cannot catch the case.
The splitter is quote-unaware. Adding `&` therefore makes any quoted text containing an ampersand followed by a kill verb classify as contamination. Measured, head versus clean base:
```
command base head
git commit -m "block sleep 1 & pkill -f mcp_server.py as recovery" False True <-- NEW
echo "docs: sleep 1 & pkill -f mcp_server.py is now detected" False True <-- NEW
grep -rn "sleep 1 & pkill -f mcp_server.py" docs/ False True <-- NEW
git commit -m "fix; pkill -f mcp_server.py" True True (pre-existing)
git commit -m "fix | pkill -f mcp_server.py" True True (pre-existing)
```
Three of these are regressions introduced by this head. The `;` and `|` rows show the underlying quote-unawareness predates this PR, so the class is not new — but this change extends it to the one separator that appears in the canonical example string, and that string is the subject of this very issue. Any commit message, doc line, or grep that quotes `sleep 1 & pkill -f mcp_server.py` now classifies as a manual daemon kill.
Why this is blocking rather than cosmetic: issue #787 scope item 4 names "a commit message quoting the kill string" as a case that must keep its non-contaminating outcome, and AC5 requires test coverage for it. The PR adds `test_commit_message_quoting_the_kill_string_is_not_a_kill`, but the string it quotes omits the ampersand, so the test passes while the very form the issue is about regresses. The named case is nominally covered and actually unprotected.
Consequence when triggered: `gitea_record_daemon_process_kill_attempt` writes a durable contamination marker, and `_enforce_runtime_recovery_contamination_gate` then fails review, merge, close and completion mutations closed. By design a worker session cannot clear it — only a reconciler can. A false marker is therefore an operator-visible stall, not a warning.
Blast radius today is bounded: `assess_recovery_command` has exactly one production consumer, `gitea_record_daemon_process_kill_attempt`, so the marker is written only when a session explicitly calls that tool. It is not yet wired to arbitrary command strings. That containment is exactly what the issue's own deferred follow-up proposes to remove by feeding the classifier from `gitea_record_pre_review_command` and `gitea_assess_gitea_operation_path`. Landing this false-positive surface first and that wiring later would turn a latent defect into a live one.
Required change, either of:
1. Preferred — make segment splitting quote-aware: walk the string tracking single/double-quote state and split only on separators found outside quotes. Roughly ten lines, no change to the classifier, and it also removes the two pre-existing `;` and `|` false positives, so the guard strictly improves.
2. Minimum — keep the current splitter but add the ampersand-bearing form of the commit-message case to the no-false-positive tests and make it pass.
Either way AC5 needs a case that quotes the full `sleep 1 & pkill -f mcp_server.py` string inside a non-executing command and asserts contamination is False.
### F2 — MINOR (evidence accuracy). The stated test counts in the PR body do not match the head.
The body states the file "held 46 cases before this change" and that "9 were added". Counted at both commits, and confirmed by collection: base `35e94e10` 47 passed, head `6b58f04` 55 passed. Eight test functions are added, not nine, and the prior count was 47, not 46. The suites themselves pass as claimed; only the arithmetic in the narrative is wrong. Please correct the body so the record is accurate.
### F3 — INFORMATIONAL. `_strip_subshell` and the widened split both treat shell syntax loosely.
`_strip_subshell` removes a trailing `)` unconditionally, so `kill $(pgrep -f myapp)` becomes `kill $(pgrep -f myapp`. No classification changes today because the remaining text still carries or lacks the daemon pattern, but the helper mangles balanced command substitution as a side effect of stripping an unbalanced wrapper. Similarly the new `&` split turns `a 2>&1` into `['a 2>', '1']`. Neither causes a wrong verdict in the cases tested; both are worth a comment or a tightened implementation if the splitter is reworked for F1.

The author's claim that these predate the branch is confirmed and they do not bear on this verdict.

AC4 (marker written for both new forms) is covered by the two new record-tool cases, which pass in the focused run above. This reviewer did not invoke the live record tool, because writing a real contamination marker would fail this session's own review mutation closed.
## Verdict rationale
AC1, AC2 and AC4 are met. AC3 is met for the cases the issue enumerates literally. AC5 is not met: the commit-message case it names is covered only in a form that cannot exercise the new code path, and the head regresses that case for the exact string the issue is about. F1 is a correctness defect in the shipped behaviour, so the verdict is request_changes.
[THREAD STATE LEDGER] PR #789 — reviewer verdict request_changes at head 6b58f04
What is true now:
- Server-side decision state: a REQUEST_CHANGES review verdict is being recorded against head `6b58f04d396b881d5d242eacac45bcfdfefe2d00`; no merge event has occurred; PR #789 remains in open state; issue #787 remains in open state.
- Local verdict/state: independent review complete at the pinned head; one blocking finding (F1), one minor evidence finding (F2), one informational finding (F3).
- Latest known validation: focused suite 55 passed at head and 47 passed at base; the five broader modules produce an identical 11-failure signature at both commits.
What changed:
- A reviewer verdict of request_changes is recorded for head `6b58f04d396b881d5d242eacac45bcfdfefe2d00`.
- No branch, lock, lease, or repository content was altered by this review.
What is blocked:
- Blocker classification: code blocker
- F1: splitting on `&` introduces three measured false positives on quoted text containing an ampersand and a kill verb, and the AC5 test for the commit-message case omits the ampersand so it cannot catch them.
Who/what acts next:
- Next actor: author
- Required action: implement F1 (preferably quote-aware segment splitting), add an AC5 case quoting the full `sleep 1 & pkill -f mcp_server.py` string inside a non-executing command asserting contamination False, correct the test-count arithmetic in the PR body for F2, and push a new head for re-review.
- Do not do: do not merge this head; do not treat the focused suite passing as evidence that the commit-message case is protected; do not widen the classifier into other tools while F1 stands.

Address reviewer findings on PR #789 (issue #787) in
Scaled-Tech-Consulting/Gitea-Tools, remote prgs. Reviewed head was
6b58f04d396b881d5d242eacac45bcfdfefe2d00.
Use only the gitea-tools author namespace. Do not review, approve, or merge.
F1 (blocking): _SEGMENT_SPLIT_RE is quote-unaware, so adding `&` made quoted
text containing an ampersand plus a kill verb classify as contamination.
Measured regressions versus base 35e94e10:
git commit -m "block sleep 1 & pkill -f mcp_server.py as recovery"
echo "docs: sleep 1 & pkill -f mcp_server.py is now detected"
grep -rn "sleep 1 & pkill -f mcp_server.py" docs/
Preferred fix: split only on separators found outside single/double quotes.
This also removes the pre-existing `;` and `|` false positives.
F1 coverage: test_commit_message_quoting_the_kill_string_is_not_a_kill quotes a
string without an ampersand, so it cannot catch the regression. Add a case
quoting the full `sleep 1 & pkill -f mcp_server.py` string inside a
non-executing command and assert contamination is False.
F2 (minor): the PR body says the file held 46 cases and 9 were added. Measured:
47 at base, 55 at head, so 8 were added. Correct the body.
F3 (informational): _strip_subshell strips a trailing `)` unconditionally, and
the new split turns `a 2>&1` into ['a 2>', '1']. Tighten or comment if the
splitter is reworked.
Keep the scope to issue #787. Re-run the focused suite plus the five broader
modules at base and at the new head, then hand off to a fresh reviewer.

WHAT_HAPPENED:
An independent reviewer examined PR #789 at head 6b58f04d396b881d5d242eacac45bcfdfefe2d00 in a dedicated detached worktree, read the two-file diff, classified 28 command strings against both the head and a clean-base copy of the guard, and ran the focused suite and five broader modules at both commits. Both forms named in issue #787 are correctly detected and operator precedence is preserved, but splitting on `&` introduced three measured false positives on quoted text, and the AC5 test that should protect the commit-message case omits the ampersand.
WHY:
A false contamination marker fails review, merge, close and completion mutations closed and can only be cleared by a reconciler, so a false positive is an operator-visible stall. The regressing string is the exact example the issue is written around, which makes a documentation or commit-message mention of #787 a trigger.

Five broader modules give an identical 11-failure signature at both commits (11 failed, 254 passed), confirming those failures predate the branch. Classification of 28 command strings run against head and clean base; both issue forms reproduce as contamination at head and as non-detection at base; three quoted-text regressions measured at head only.

Review #497 on PR #789 found that adding `&` to the separator alternation
created a new false-positive class: the splitter was quote-unaware, so any
quoted text carrying an ampersand and a kill verb classified as a manual
daemon kill. Three commands regressed against base 35e94e10, all of which
merely mention the canonical kill string:
git commit -m "block sleep 1 & pkill -f mcp_server.py as recovery"
echo "docs: sleep 1 & pkill -f mcp_server.py is now detected"
grep -rn "sleep 1 & pkill -f mcp_server.py" docs/
A false contamination marker fails review, merge, close and completion
mutations closed and only a reconciler may clear it, so this is an
operator-visible stall rather than a warning.
F1: replace the `_SEGMENT_SPLIT_RE` alternation with a quote-aware scan.
`_iter_active` yields only the character positions where a metacharacter is
syntactically active — outside single and double quotes, not backslash
escaped — and `_split_segments` separates only there. This fixes the class
rather than the three named instances, and also retires the `;` and `|`
false positives that predate #787. `&&` and `||` are still consumed whole,
so logical-separator precedence is unchanged.
F3: `_strip_subshell` now removes a trailing `)` only when it closes a
leading `(` this call stripped, so `kill $(pgrep -f myapp)` is no longer
mangled into `kill $(pgrep -f myapp`; and `_is_redirection` keeps `2>&1`,
`>&2` and `&>log` from being read as background separators. Neither changed
a verdict at the rejected head, but both are corrected here because the
splitter was reworked for F1.
Nine focused cases added: the three F1 commands, double-quoted, single-quoted
and backslash-escaped ampersands, the POSIX rule that a backslash does not
escape inside single quotes, the `;`/`|` class, the two F3 forms, and a
record-tool case asserting no marker is written for a quoted mention.
Focused suite 64 passed (47 at base 35e94e10, 55 at rejected head 6b58f04).
Full suite 11 failed, 4190 passed, 6 skipped; the same 11 failures occur
test-for-test at base and are unrelated to this branch.

Scope examined
Diff versus base master 35e94e107c32cfdc4b9ab9a95cb4e94df94077d4: two files, 321 insertions, 4 deletions.
runtime_recovery_guard.py — _SEGMENT_SPLIT_RE removed; new _iter_active, _is_redirection, _closes_leading_paren; _strip_subshell rewritten; _split_segments rewritten as a scan.
tests/test_issue_630_runtime_recovery_guard.py — new cases only, no existing case weakened or deleted.
The classifier itself (_analyse_kill_segment, classify_recovery_command, assess_recovery_command), the contamination model, the gated-task set, the marker lifecycle, and the reconciler-only clearing path are untouched. No widening of detection into other tools. Scope discipline for #787 holds.
The splitter is now quote-aware. _iter_active() walks the string tracking single- and double-quote state and backslash escaping, yielding only positions where a metacharacter is syntactically active; _split_segments() separates only at those positions. This is the preferred remedy #497 named, and it addresses the class rather than the three measured strings.
All three measured regressions are gone, and the two pre-existing ;/| false positives #497 documented are retired as well — so the head is strictly better than base on this axis, not merely better than the rejected head. Measured this session at all three commits:
Every row where base reads True and the head reads False is a command that executes no kill at all under shell semantics — an escaped or quoted separator makes the text an argument, not syntax — so each is a false positive being retired, never a detection being lost.
AC5 coverage is now real. F1_QUOTED_COMMANDS holds the full ampersand-bearing strings and is asserted twice: once against the classifier (test_quoted_ampersand_examples_from_review_f1_are_not_kills) and once against the marker-writing tool (test_record_tool_does_not_mark_a_quoted_mention_of_the_kill_string, asserting contaminated is False, marked is False, and _load_runtime_recovery_marker(...) is None). The second assertion is the one that matters operationally, because the marker is what fails mutations closed. Single-quoted, escaped, and escaped-inside-single-quote forms carry their own cases.
F2 (MINOR, evidence accuracy) — RESOLVED
The body now states 47 at base, 55 at the rejected head, 64 at this head, and says the rejected head added 8 cases rather than 9. Re-counted independently this session in three separate detached worktrees; the corrected figures are exact. Full-suite pass counts corroborate the arithmetic: base 4173 passed versus head 4190 passed, a difference of 17, matching 64 − 47.
F3 (INFORMATIONAL) — RESOLVED
_strip_subshell now removes a trailing ) only when _closes_leading_paren() proves it closes a ( this call stripped, tracking nesting over active characters. kill $(pgrep -f myapp) is returned intact, and (kill $(pgrep -f myapp)) unwraps to kill $(pgrep -f myapp) with the substitution balanced. An unmatched leading ( is still dropped alone, which is required because splitting a wrapped compound orphans the opening half. _is_redirection() keeps 2>&1, >&2 and &>log out of separator position.
Segmentation properties verified
Verified by direct calls to _split_segments at the pinned head, not inferred from the tests:
a && b || c -> ['a', 'b', 'c'] (&& / || consumed whole)
a & b -> ['a', 'b'] (active &)
a; b\nc | d -> ['a', 'b', 'c', 'd'] (active ; newline |)
echo "a & b" -> ['echo "a & b"'] (double-quoted, inert)
echo 'a & b' -> ["echo 'a & b'"] (single-quoted, inert)
echo a \& pkill -f x -> ['echo a \\& pkill -f x'] (escaped, inert)
echo a \; pkill -f x -> ['echo a \\; pkill -f x'] (escaped, inert)
echo "x"&pkill -f mcp_server.py -> ['echo "x"', 'pkill -f mcp_server.py'] (active right after close quote)
echo a\ & pkill -f mcp_server.py -> ['echo a\\', 'pkill -f mcp_server.py'] (escaped space, then active &)
a 2>&1 -> ['a 2>&1'] (redirection, not a separator)
a >&2 -> ['a >&2']
a &> log -> ['a &> log']
a >| b -> ['a >| b'] (noclobber override)
a 2>&1 & pkill -f mcp_server.py -> ['a 2>&1', 'pkill -f mcp_server.py'] (redirection then a real &)
a && b & pkill -f mcp_server.py -> ['a', 'b', 'pkill -f mcp_server.py'] (mixed logical + background)
a |& pkill -f mcp_server.py -> ['a', 'pkill -f mcp_server.py']
kill $(pgrep -f myapp) -> ['kill $(pgrep -f myapp)'] (substitution intact)
(pkill -f mcp_server.py) -> ['pkill -f mcp_server.py']
((pkill -f gitea_mcp_server)) -> ['pkill -f gitea_mcp_server']
(kill $(pgrep -f myapp)) -> ['kill $(pgrep -f myapp)']
(ps aux | grep mcp_server) & pkill ... -> ['ps aux', 'grep mcp_server)', 'pkill -f mcp_server.py']
The last eight rows are cases the diff does not name and the tests do not assert, chosen to test generality rather than the reported examples; each matches shell semantics. echo "x"&pkill ... and echo a\ & pkill ... are the important ones: quote-awareness does not make a separator inert merely because quoting appears earlier in the line, so the fix suppresses false positives without opening an evasion path.
True-positive reproductions at the pinned head
All required forms classify as contamination with reason_class=manual_daemon_kill (broad sweep as broad_process_kill), reproduced this session:
echo 'a\' & pkill -f mcp_server.py is the sharp case: POSIX gives a backslash no escaping power inside single quotes, so the quote closes and the & is genuinely active. The head detects it, which shows the quote handling is a faithful shell model rather than a blunt "ignore anything near a quote" rule.
No-false-positive cases, unchanged at all three commits
ps aux | grep mcp_server process_kill=False contamination=False
pkill -u mcpuser -f myapp process_kill=True contamination=False ambiguous=False
kill 31337 process_kill=True contamination=False ambiguous=True
kill $(pgrep -f myapp) process_kill=True contamination=False ambiguous=True
pkill -f myapp process_kill=True contamination=False
npm run dev & sleep 2 process_kill=False contamination=False
systemctl restart myapp && echo ok process_kill=False contamination=False
a 2>&1 / a >&2 / a &> log process_kill=False contamination=False
Marker-creation proof
assess_recovery_command still has exactly one production consumer: gitea_mcp_server.py:15980, inside gitea_record_daemon_process_kill_attempt. Verified by repository-wide search at the pinned head for assess_recovery_command, classify_recovery_command and build_contamination_record outside tests/. That consumer writes a marker only under if contaminated and mark: (gitea_mcp_server.py:15990), where contaminated requires classifier contamination and absent operator authorization. That file is not in this diff, so the marker lifecycle is unchanged; the head narrows what reaches the marker rather than changing when a marker is written. The record-tool tests assert marker creation for both newly detected forms and absence of a marker for all three quoted mentions.
Test evidence
All commands run by this reviewer with an absolute interpreter path, in the stated working directory. No repository file was edited. All three worktrees are session-owned, detached, and were clean before and after every run.

Validation failure history
The full suite at the pinned head exited 1 with 11 failing tests. No rerun was performed and no failure was made to disappear; the failures are dispositioned by the pre-merge baseline comparison below rather than by retry.
Suspected cause: host/workspace-state dependent preflight and commit-payload fixtures, unrelated to shell segmentation. Reproduced: yes, deterministically. Evidence that they are not caused by this change: none of the five modules imports or exercises runtime_recovery_guard, and the identical set fails on the pre-merge base commit with this change absent.
Pre-merge baseline proof
The comparison was run as a full suite at both commits, not only on the five affected modules, so the equivalence claim rests on the whole surface. The baseline commit is the pre-merge base of this branch, not post-merge master: aa4fe1cc has not landed, so 35e94e10 is master as it stands without this work.

The 17-test pass-count difference (4173 to 4190) equals the focused-suite delta (47 to 64), so the head adds tests and removes none. The author's claim that the same 11 failures reproduce on clean base is confirmed, and confirmed on a wider basis than the author measured.

re-acquired under the same session id 17962-46269707ca04, comment 13843, after the 10-minute lease TTL lapsed during validation; gitea_assess_reviewer_pr_lease first proved active_lease: null, so no foreign lease was displaced
gitea_whoami then gitea_resolve_task_capability(task="review_pr") re-resolved immediately before the call

No mutation beyond review was performed by this session. Merge capability (merge_pr / gitea.pr.merge) and branch-delete capability (gitea.branch.delete) are both absent from this profile and neither was attempted.
Findings and severity
No blocking findings. No correctness, safety, scope or coverage problem remains. Two informational observations, neither a regression and neither in scope for #787:
I1 — INFORMATIONAL. A line with an unterminated quote swallows its tail, so echo "oops & pkill -f mcp_server.py classifies as no kill. This is documented in the _iter_active docstring and matches the shell, which rejects such a line as a syntax error rather than running its tail. The classifier's only consumer receives a command string a session voluntarily self-reports, so a syntactically invalid line is not a route by which a real kill escapes an honest report.
I2 — INFORMATIONAL. A brace group and an explicit interpreter still bypass the classifier: { pkill -f mcp_server.py; } and sh -c 'pkill -f mcp_server.py' both classify as no kill. Measured at base and at this head, identical at both, so this predates the branch and is not a regression. Issue #787 names only the subshell wrapper, and widening the tokenizer further belongs with the deferred follow-up that would feed the classifier automatically from other tools.
Verdict rationale
Issue #787 acceptance criteria, each checked against the pinned head this session:
AC1 — met. sleep 1 & pkill -f mcp_server.py classifies as contamination with reason class manual_daemon_kill.
AC2 — met. (pkill -f mcp_server.py) classifies as contamination with reason class manual_daemon_kill.
AC3 — met. pkill -u mcpuser -f myapp stays non-contaminating and unambiguous; kill 31337 and kill $(pgrep -f myapp) stay ambiguous and non-contaminating.
AC4 — met. The record tool writes a durable marker for both newly detected forms, covered by passing cases in the focused run.
AC5 — met. Both forms plus all four no-false-positive cases from scope item 4 are covered, and the commit-message case is now asserted with the full ampersand-bearing string against both the classifier and the marker-writing tool — the exact gap that made review #497 blocking.
The remediation is a genuine class fix rather than a patch over the three reported strings: it is expressed as shell syntax rules, it generalizes to cases neither the diff nor its tests name, and it retires two false positives that predate this issue. No true positive was lost anywhere between base and this head. The full-suite failures are proven baseline-equivalent on a whole-suite basis. Findings F1, F2 and F3 are each resolved, and no material regression was found, so the verdict is approve.
[THREAD STATE LEDGER] PR #789 — reviewer verdict approve at head aa4fe1cc
What is true now:
Server-side decision state: an APPROVE review verdict is being recorded against head aa4fe1cc7bd2d6f07ea35775a5c5292d94a938e0; no merge event has occurred; PR #789 remains in open state; issue #787 remains in open state.
Local verdict/state: independent re-review complete at the pinned head; findings F1, F2 and F3 from review #497 are each resolved; no blocking finding; two informational observations recorded, both pre-existing and out of scope.
Latest known validation: focused suite 64 passed at this head, 55 at the rejected head, 47 at base; full suite 11 failed / 4190 passed at this head and 11 failed / 4173 passed at base with identical failing test ids.
What changed:
A reviewer verdict of approve is recorded for head aa4fe1cc7bd2d6f07ea35775a5c5292d94a938e0.
A reviewer PR lease was acquired, heartbeated, and re-acquired for PR #789 under one session id 17962-46269707ca04 (comments 13838, 13840 and 13843); the re-acquisition followed a lapsed 10-minute TTL on this session's own lease, with active_lease: null proven first.
Three session-owned detached worktrees were created under branches/. No branch, lock, or repository content was altered.
What is blocked:
Blocker classification: no blocker
Nothing is blocked. Review #497 is superseded by this verdict at the newer head.
Who/what acts next:
Next actor: merger
Required action: adopt the reviewer lease for PR #789 through gitea_adopt_merger_pr_lease pinned to aa4fe1cc7bd2d6f07ea35775a5c5292d94a938e0, re-run merge preflight including gitea_assess_pr_sync_status, and complete the merge only while the live head still equals the approved head.
Do not do: do not merge at any head other than aa4fe1cc; do not treat review #497 as still blocking; do not re-review or re-approve; do not delete the author worktree or another session's worktrees.

WHO_IS_NEXT:

NEXT_ACTION:
Merger adopts the reviewer lease for PR #789 at head aa4fe1cc7b, re-runs merge preflight, and completes the merge only while the live head equals the approved head.
NEXT_PROMPT:
Merge PR #789 (issue #787) in Scaled-Tech-Consulting/Gitea-Tools, remote prgs,
using only the gitea-merger namespace and the canonical review-merge workflow.
Approved head: aa4fe1cc7bd2d6f07ea35775a5c5292d94a938e0
Base master: 35e94e107c32cfdc4b9ab9a95cb4e94df94077d4
Approving review: this reviewer verdict, recorded at that exact head.
Preflight: load the canonical review-merge workflow, prove identity is
sysadmin / prgs-merger with role merger, prove runtime/master parity, confirm
PR #789 is still open and mergeable, confirm the live head is still exactly
aa4fe1cc7bd2d6f07ea35775a5c5292d94a938e0, and confirm approval_at_current_head
is true via gitea_get_pr_review_feedback. Call gitea_assess_pr_sync_status and
proceed only when recommended_next_action is merge_now.
Adopt the reviewer lease with gitea_adopt_merger_pr_lease from a clean merger
worktree under branches/, passing expected_head_sha pinned to the approved head.
Never seed a lease manually and never steal a foreign lease. Note the reviewer
lease carries a 10-minute sliding TTL, so re-acquire your own before a long step
rather than adopting a lapsed one.
Then call gitea_merge_pr — blocked for the reviewer profile that produced this
handoff, so it belongs to the merger session alone. If the live head has moved,
stop: the approval is void and a fresh review at the new head is required. After
a successful merge, hand post-merge branch and worktree cleanup to a
prgs-reconciler session with gitea.branch.delete capability proof; do not clean
up inline and do not use raw git for branch deletion.
WHAT_HAPPENED:
An independent reviewer that did not author or remediate this work examined it at head aa4fe1cc7b in a dedicated detached worktree, read the full two-file diff, exercised the segmentation scan directly on 22 syntax cases beyond those the diff names, classified 47 command strings against this head, the rejected head 6b58f04 and clean base 35e94e10, and ran the focused suite at all three commits plus the full suite at this head and at base. The quote-aware splitter resolves review #497 finding F1 for the class rather than the reported examples, removes two false positives that predate the issue, loses no true positive, and finding F3's subshell and redirection defects are corrected; the corrected test counts required by F2 match the head exactly.
WHY:
A false contamination marker fails review, merge, close and completion mutations closed and only a reconciler may clear it, so the false-positive class that made review #497 blocking had to be closed as a class before this change could land. It is, and the detection required by issue #787 is intact.
VALIDATION:
Focused suite 64 passed at head aa4fe1cc, 55 passed at rejected head 6b58f04, 47 passed at base 35e94e10, each in its own detached worktree. Full suite 11 failed / 4190 passed / 6 skipped at this head and 11 failed / 4173 passed / 6 skipped at base, with identical failing test ids, so the failures are baseline-equivalent; the 17-test pass-count difference equals the focused-suite delta. Classification of 47 command strings run at all three commits plus 22 direct segmentation cases at the head; all required true positives detected, all required false positives retired.

Worktree/index mutations: three detached worktrees created under branches/ — review-pr789-aa4fe1cc at aa4fe1cc, baseline-master-pr789 at 35e94e10, review-789-rejected-6b58f04 at 6b58f04; no index or working-tree change in any of them; all three are retained for the merger and no local checkout was deleted
Git ref mutations: one git fetch from remote prgs updating refs/remotes/prgs/master and refs/remotes/prgs/fix/issue-787-kill-segment-separators; two read-only git ls-remote calls; no branch created, moved, or deleted
MCP/Gitea mutations: reviewer PR lease acquired (comment 13838), heartbeated (comment 13840) and re-acquired under the same session id after its TTL lapsed (comment 13843) on PR #789; one review verdict recorded on PR #789
Review mutations: one — APPROVE on PR #789 at head aa4fe1cc7b
Current status: independent re-review complete at the pinned head; approve verdict recorded; PR #789 stays in open state awaiting a merger
Next actor: merger
Next action: a merger session adopts the reviewer lease for PR #789 pinned to aa4fe1cc7b, re-runs merge preflight, and completes the merge only while the live head equals the approved head
Next prompt: Merge PR #789 (issue #787) in Scaled-Tech-Consulting/Gitea-Tools, remote prgs, using only the gitea-merger namespace and the canonical review-merge workflow, at approved head aa4fe1cc7b over base master 35e94e107c. The full paste-able text is in the NEXT_PROMPT block above.
Safe next action: a merger session adopts the reviewer lease for PR #789 pinned to aa4fe1cc7b, re-runs merge preflight, and completes the merge only while the live head equals the approved head
Safety statement: no lease or lock was stolen, replaced, or edited — the one re-acquisition was of this session's own lapsed lease under the same session id, with active_lease: null proven first; no lock file touched; no process killed; no daemon restarted; the author namespace was not used for any action; no direct API calls, curl, tea or gh; no branch or repository content modified; the author worktree and the two worktrees owned by the prior reviewer session were inspected for status only and left untouched; the three worktrees created by this session are the only local repository artifacts

This is an independent re-review by a session that did not author or remediate this pull request. The author handoff and its reported numbers were treated as claims to verify, not as evidence. Every count and every classification below was re-measured in this session.
Prior-landing gate: NOT_LANDED — the pull request is in open state, `merged_at` null, `merge_commit_sha` null, and `git merge-base --is-ancestor aa4fe1cc prgs/master` returned non-zero, so head aa4fe1cc is not an ancestor of the target branch.

## Prior request-changes state
Review #497 by sysadmin, submitted 2026-07-21T20:19:51-05:00, REQUEST_CHANGES at head `6b58f04d396b881d5d242eacac45bcfdfefe2d00`. It is visible, `dismissed=false`, `stale=true`, not quarantined. The head advanced to `aa4fe1cc` afterwards (`author_pushed_after_request_changes=true`), so the blocker is evaluated against new code rather than reused. No newer substantive review exists: `gitea_get_pr_review_feedback` returns exactly one review, `latest_review_state_by_reviewer={"sysadmin": "REQUEST_CHANGES"}`, `approval_visible=false`. No conflicting reviewer or merger lease existed at acquisition (`gitea_list_workflow_leases` count 0; `gitea_assess_pr_sync_status` reported `author_lock=false, reviewer_lease=false, merger_lease=false`).
## Scope examined
Diff versus base master `35e94e107c32cfdc4b9ab9a95cb4e94df94077d4`: two files, 321 insertions, 4 deletions.
- `runtime_recovery_guard.py` — `_SEGMENT_SPLIT_RE` removed; new `_iter_active`, `_is_redirection`, `_closes_leading_paren`; `_strip_subshell` rewritten; `_split_segments` rewritten as a scan.
- `tests/test_issue_630_runtime_recovery_guard.py` — new cases only, no existing case weakened or deleted.
The classifier itself (`_analyse_kill_segment`, `classify_recovery_command`, `assess_recovery_command`), the contamination model, the gated-task set, the marker lifecycle, and the reconciler-only clearing path are untouched. No widening of detection into other tools. Scope discipline for #787 holds.
## Disposition of review #497 findings
### F1 (BLOCKING at `6b58f04`) — RESOLVED
The splitter is now quote-aware. `_iter_active()` walks the string tracking single- and double-quote state and backslash escaping, yielding only positions where a metacharacter is syntactically active; `_split_segments()` separates only at those positions. This is the preferred remedy #497 named, and it addresses the class rather than the three measured strings.
All three measured regressions are gone, and the two pre-existing `;`/`|` false positives #497 documented are retired as well — so the head is strictly better than base on this axis, not merely better than the rejected head. Measured this session at all three commits:
```
command base 35e94e10 rejected 6b58f04 head aa4fe1cc
git commit -m "block sleep 1 & pkill -f mcp_server.py as recovery" False True False
echo "docs: sleep 1 & pkill -f mcp_server.py is now detected" False True False
grep -rn "sleep 1 & pkill -f mcp_server.py" docs/ False True False
git commit -m 'block sleep 1 & pkill ... as recovery' (single-q) False True False
echo 'docs: sleep 1 & pkill ... is now detected' (single-q) False True False
grep -rn 'sleep 1 & pkill -f mcp_server.py' docs/ (single-q) False True False
echo a \& pkill -f mcp_server.py (escaped) False True False
echo a \; pkill -f mcp_server.py (escaped) True True False
echo a \| pkill -f mcp_server.py (escaped) True True False
git commit -m "fix; pkill -f mcp_server.py" (quoted ;) True True False
git commit -m "fix | pkill -f mcp_server.py" (quoted |) True True False
git commit -m 'fix; pkill -f mcp_server.py' (quoted ;) True True False
echo "a\" & pkill -f mcp_server.py" (esc. quote) False True False
```
Every row where base reads True and the head reads False is a command that executes no kill at all under shell semantics — an escaped or quoted separator makes the text an argument, not syntax — so each is a false positive being retired, never a detection being lost.
AC5 coverage is now real. `F1_QUOTED_COMMANDS` holds the full ampersand-bearing strings and is asserted twice: once against the classifier (`test_quoted_ampersand_examples_from_review_f1_are_not_kills`) and once against the marker-writing tool (`test_record_tool_does_not_mark_a_quoted_mention_of_the_kill_string`, asserting `contaminated is False`, `marked is False`, and `_load_runtime_recovery_marker(...) is None`). The second assertion is the one that matters operationally, because the marker is what fails mutations closed. Single-quoted, escaped, and escaped-inside-single-quote forms carry their own cases.
### F2 (MINOR, evidence accuracy) — RESOLVED
The body now states 47 at base, 55 at the rejected head, 64 at this head, and says the rejected head added 8 cases rather than 9. Re-counted independently this session in three separate detached worktrees; the corrected figures are exact. Full-suite pass counts corroborate the arithmetic: base 4173 passed versus head 4190 passed, a difference of 17, matching 64 − 47.
### F3 (INFORMATIONAL) — RESOLVED
`_strip_subshell` now removes a trailing `)` only when `_closes_leading_paren()` proves it closes a `(` this call stripped, tracking nesting over active characters. `kill $(pgrep -f myapp)` is returned intact, and `(kill $(pgrep -f myapp))` unwraps to `kill $(pgrep -f myapp)` with the substitution balanced. An unmatched leading `(` is still dropped alone, which is required because splitting a wrapped compound orphans the opening half. `_is_redirection()` keeps `2>&1`, `>&2` and `&>log` out of separator position.
## Segmentation properties verified
Verified by direct calls to `_split_segments` at the pinned head, not inferred from the tests:
```
a && b || c -> ['a', 'b', 'c'] (&& / || consumed whole)
a & b -> ['a', 'b'] (active &)
a; b\nc | d -> ['a', 'b', 'c', 'd'] (active ; newline |)
echo "a & b" -> ['echo "a & b"'] (double-quoted, inert)
echo 'a & b' -> ["echo 'a & b'"] (single-quoted, inert)
echo a \& pkill -f x -> ['echo a \\& pkill -f x'] (escaped, inert)
echo a \; pkill -f x -> ['echo a \\; pkill -f x'] (escaped, inert)
echo "x"&pkill -f mcp_server.py -> ['echo "x"', 'pkill -f mcp_server.py'] (active right after close quote)
echo a\ & pkill -f mcp_server.py -> ['echo a\\', 'pkill -f mcp_server.py'] (escaped space, then active &)
a 2>&1 -> ['a 2>&1'] (redirection, not a separator)
a >&2 -> ['a >&2']
a &> log -> ['a &> log']
a >| b -> ['a >| b'] (noclobber override)
a 2>&1 & pkill -f mcp_server.py -> ['a 2>&1', 'pkill -f mcp_server.py'] (redirection then a real &)
a && b & pkill -f mcp_server.py -> ['a', 'b', 'pkill -f mcp_server.py'] (mixed logical + background)
a |& pkill -f mcp_server.py -> ['a', 'pkill -f mcp_server.py']
kill $(pgrep -f myapp) -> ['kill $(pgrep -f myapp)'] (substitution intact)
(pkill -f mcp_server.py) -> ['pkill -f mcp_server.py']
((pkill -f gitea_mcp_server)) -> ['pkill -f gitea_mcp_server']
(kill $(pgrep -f myapp)) -> ['kill $(pgrep -f myapp)']
(ps aux | grep mcp_server) & pkill ... -> ['ps aux', 'grep mcp_server)', 'pkill -f mcp_server.py']
```
The last eight rows are cases the diff does not name and the tests do not assert, chosen to test generality rather than the reported examples; each matches shell semantics. `echo "x"&pkill ...` and `echo a\ & pkill ...` are the important ones: quote-awareness does not make a separator inert merely because quoting appears earlier in the line, so the fix suppresses false positives without opening an evasion path.
## True-positive reproductions at the pinned head
All required forms classify as contamination with `reason_class=manual_daemon_kill` (broad sweep as `broad_process_kill`), reproduced this session:
```
sleep 1 & pkill -f mcp_server.py contamination=True manual_daemon_kill
(pkill -f mcp_server.py) contamination=True manual_daemon_kill
pkill -f mcp_server.py contamination=True manual_daemon_kill
pkill -f gitea_mcp_server contamination=True manual_daemon_kill
killall mcp_server contamination=True manual_daemon_kill
sudo pkill -f mcp_server.py contamination=True manual_daemon_kill
/usr/bin/pkill -f mcp_server.py contamination=True manual_daemon_kill
env FOO=1 pkill -f mcp_server.py contamination=True manual_daemon_kill
true && false || pkill -f mcp_server.py contamination=True manual_daemon_kill
pkill -f mcp_server.py & contamination=True manual_daemon_kill
nohup pkill -f mcp_server.py & contamination=True manual_daemon_kill
((pkill -f gitea_mcp_server)) contamination=True manual_daemon_kill
( sudo pkill -f mcp_server.py ) contamination=True manual_daemon_kill
(ps aux | grep mcp_server) & pkill -f mcp_server.py contamination=True manual_daemon_kill
sleep 1 & killall mcp_server contamination=True manual_daemon_kill
kill $(pgrep -f mcp_server.py) contamination=True manual_daemon_kill
pkill -f mcp_server.py 2>&1 contamination=True manual_daemon_kill
echo hi; pkill -f mcp_server.py contamination=True manual_daemon_kill
echo "hi" ; pkill -f mcp_server.py contamination=True manual_daemon_kill
echo hi\npkill -f mcp_server.py contamination=True manual_daemon_kill
sleep 1 &\npkill -f mcp_server.py contamination=True manual_daemon_kill
echo 'a\' & pkill -f mcp_server.py contamination=True manual_daemon_kill
pkill -f python contamination=True broad_process_kill
```
`echo 'a\' & pkill -f mcp_server.py` is the sharp case: POSIX gives a backslash no escaping power inside single quotes, so the quote closes and the `&` is genuinely active. The head detects it, which shows the quote handling is a faithful shell model rather than a blunt "ignore anything near a quote" rule.
## No-false-positive cases, unchanged at all three commits
```
ps aux | grep mcp_server process_kill=False contamination=False
pkill -u mcpuser -f myapp process_kill=True contamination=False ambiguous=False
kill 31337 process_kill=True contamination=False ambiguous=True
kill $(pgrep -f myapp) process_kill=True contamination=False ambiguous=True
pkill -f myapp process_kill=True contamination=False
npm run dev & sleep 2 process_kill=False contamination=False
systemctl restart myapp && echo ok process_kill=False contamination=False
a 2>&1 / a >&2 / a &> log process_kill=False contamination=False
```
## Marker-creation proof
`assess_recovery_command` still has exactly one production consumer: `gitea_mcp_server.py:15980`, inside `gitea_record_daemon_process_kill_attempt`. Verified by repository-wide search at the pinned head for `assess_recovery_command`, `classify_recovery_command` and `build_contamination_record` outside `tests/`. That consumer writes a marker only under `if contaminated and mark:` (`gitea_mcp_server.py:15990`), where `contaminated` requires classifier contamination **and** absent operator authorization. That file is not in this diff, so the marker lifecycle is unchanged; the head narrows what reaches the marker rather than changing when a marker is written. The record-tool tests assert marker creation for both newly detected forms and absence of a marker for all three quoted mentions.
## Test evidence
All commands run by this reviewer with an absolute interpreter path, in the stated working directory. No repository file was edited. All three worktrees are session-owned, detached, and were clean before and after every run.

## Validation failure history
The full suite at the pinned head exited 1 with 11 failing tests. No rerun was performed and no failure was made to disappear; the failures are dispositioned by the pre-merge baseline comparison below rather than by retry.
- `tests/test_commit_payloads.py` — 6 failures (`test_commit_files_content_plain`, `test_commit_files_local_path`, `test_commit_files_multiple_sources_blocked`, `test_commit_files_outside_scope_blocked`, `test_commit_files_traversal_blocked`, `test_commit_files_workspace_path`)

- `tests/test_post_merge_moot_lease.py::TestAcquireToolRefusesMergedPR::test_acquire_tool_fails_closed_on_merged_pr_without_posting` — 1 failure
- `tests/test_reconciler_supersession_close.py::TestReconcilerSupersessionMcpTool::test_tool_posts_comment_and_closes_superseded_pr_issue` — 1 failure
Suspected cause: host/workspace-state dependent preflight and commit-payload fixtures, unrelated to shell segmentation. Reproduced: yes, deterministically. Evidence that they are not caused by this change: none of the five modules imports or exercises `runtime_recovery_guard`, and the identical set fails on the pre-merge base commit with this change absent.
## Pre-merge baseline proof
The comparison was run as a full suite at both commits, not only on the five affected modules, so the equivalence claim rests on the whole surface. The baseline commit is the pre-merge base of this branch, not post-merge master: `aa4fe1cc` has not landed, so `35e94e10` is master as it stands without this work.

The 17-test pass-count difference (4173 to 4190) equals the focused-suite delta (47 to 64), so the head adds tests and removes none. The author's claim that the same 11 failures reproduce on clean base is confirmed, and confirmed on a wider basis than the author measured.

No mutation beyond review was performed by this session. Merge capability (`merge_pr` / `gitea.pr.merge`) and branch-delete capability (`gitea.branch.delete`) are both absent from this profile and neither was attempted.
## Findings and severity
No blocking findings. No correctness, safety, scope or coverage problem remains. Two informational observations, neither a regression and neither in scope for #787:
- **I1 — INFORMATIONAL.** A line with an unterminated quote swallows its tail, so `echo "oops & pkill -f mcp_server.py` classifies as no kill. This is documented in the `_iter_active` docstring and matches the shell, which rejects such a line as a syntax error rather than running its tail. The classifier's only consumer receives a command string a session voluntarily self-reports, so a syntactically invalid line is not a route by which a real kill escapes an honest report.
- **I2 — INFORMATIONAL.** A brace group and an explicit interpreter still bypass the classifier: `{ pkill -f mcp_server.py; }` and `sh -c 'pkill -f mcp_server.py'` both classify as no kill. Measured at base and at this head, identical at both, so this predates the branch and is not a regression. Issue #787 names only the subshell wrapper, and widening the tokenizer further belongs with the deferred follow-up that would feed the classifier automatically from other tools.
## Verdict rationale
Issue #787 acceptance criteria, each checked against the pinned head this session:
- AC1 — met. `sleep 1 & pkill -f mcp_server.py` classifies as contamination with reason class `manual_daemon_kill`.
- AC2 — met. `(pkill -f mcp_server.py)` classifies as contamination with reason class `manual_daemon_kill`.
- AC3 — met. `pkill -u mcpuser -f myapp` stays non-contaminating and unambiguous; `kill 31337` and `kill $(pgrep -f myapp)` stay ambiguous and non-contaminating.
- AC4 — met. The record tool writes a durable marker for both newly detected forms, covered by passing cases in the focused run.
- AC5 — met. Both forms plus all four no-false-positive cases from scope item 4 are covered, and the commit-message case is now asserted with the full ampersand-bearing string against both the classifier and the marker-writing tool — the exact gap that made review #497 blocking.
The remediation is a genuine class fix rather than a patch over the three reported strings: it is expressed as shell syntax rules, it generalizes to cases neither the diff nor its tests name, and it retires two false positives that predate this issue. No true positive was lost anywhere between base and this head. The full-suite failures are proven baseline-equivalent on a whole-suite basis. Findings F1, F2 and F3 are each resolved, and no material regression was found, so the verdict is approve.
[THREAD STATE LEDGER] PR #789 — reviewer verdict approve at head aa4fe1cc
What is true now:
- Server-side decision state: an APPROVE review verdict is being recorded against head `aa4fe1cc7bd2d6f07ea35775a5c5292d94a938e0`; no merge event has occurred; PR #789 remains in open state; issue #787 remains in open state.
- Local verdict/state: independent re-review complete at the pinned head; findings F1, F2 and F3 from review #497 are each resolved; no blocking finding; two informational observations recorded, both pre-existing and out of scope.
- Latest known validation: focused suite 64 passed at this head, 55 at the rejected head, 47 at base; full suite 11 failed / 4190 passed at this head and 11 failed / 4173 passed at base with identical failing test ids.
What changed:
- A reviewer verdict of approve is recorded for head `aa4fe1cc7bd2d6f07ea35775a5c5292d94a938e0`.
- A reviewer PR lease was acquired, heartbeated, and re-acquired for PR #789 under one session id `17962-46269707ca04` (comments 13838, 13840 and 13843); the re-acquisition followed a lapsed 10-minute TTL on this session's own lease, with `active_lease: null` proven first.
- Three session-owned detached worktrees were created under `branches/`. No branch, lock, or repository content was altered.

- Blocker classification: no blocker
- Nothing is blocked. Review #497 is superseded by this verdict at the newer head.
Who/what acts next:

Merge PR #789 (issue #787) in Scaled-Tech-Consulting/Gitea-Tools, remote prgs,
using only the gitea-merger namespace and the canonical review-merge workflow.
Approved head: aa4fe1cc7bd2d6f07ea35775a5c5292d94a938e0
Base master: 35e94e107c32cfdc4b9ab9a95cb4e94df94077d4
Approving review: this reviewer verdict, recorded at that exact head.
Preflight: load the canonical review-merge workflow, prove identity is
sysadmin / prgs-merger with role merger, prove runtime/master parity, confirm
PR #789 is still open and mergeable, confirm the live head is still exactly
aa4fe1cc7bd2d6f07ea35775a5c5292d94a938e0, and confirm approval_at_current_head
is true via gitea_get_pr_review_feedback. Call gitea_assess_pr_sync_status and
proceed only when recommended_next_action is merge_now.
Adopt the reviewer lease with gitea_adopt_merger_pr_lease from a clean merger
worktree under branches/, passing expected_head_sha pinned to the approved head.
Never seed a lease manually and never steal a foreign lease. Note the reviewer
lease carries a 10-minute sliding TTL, so re-acquire your own before a long step
rather than adopting a lapsed one.
Then call gitea_merge_pr — blocked for the reviewer profile that produced this
handoff, so it belongs to the merger session alone. If the live head has moved,
stop: the approval is void and a fresh review at the new head is required. After
a successful merge, hand post-merge branch and worktree cleanup to a
prgs-reconciler session with gitea.branch.delete capability proof; do not clean
up inline and do not use raw git for branch deletion.
```
WHAT_HAPPENED:
An independent reviewer that did not author or remediate this work examined it at head aa4fe1cc7bd2d6f07ea35775a5c5292d94a938e0 in a dedicated detached worktree, read the full two-file diff, exercised the segmentation scan directly on 22 syntax cases beyond those the diff names, classified 47 command strings against this head, the rejected head 6b58f04 and clean base 35e94e10, and ran the focused suite at all three commits plus the full suite at this head and at base. The quote-aware splitter resolves review #497 finding F1 for the class rather than the reported examples, removes two false positives that predate the issue, loses no true positive, and finding F3's subshell and redirection defects are corrected; the corrected test counts required by F2 match the head exactly.
WHY:
A false contamination marker fails review, merge, close and completion mutations closed and only a reconciler may clear it, so the false-positive class that made review #497 blocking had to be closed as a class before this change could land. It is, and the detection required by issue #787 is intact.

Full suite 11 failed / 4190 passed / 6 skipped at this head and 11 failed / 4173 passed / 6 skipped at base, with identical failing test ids, so the failures are baseline-equivalent; the 17-test pass-count difference equals the focused-suite delta. Classification of 47 command strings run at all three commits plus 22 direct segmentation cases at the head; all required true positives detected, all required false positives retired.

[THREAD STATE LEDGER] PR #789 post-merge reconciliation — worktree cleanup complete, source branch retained under an active worktree binding
What is true now:
Server-side decision state: no review or merge decision state was changed by this session. PR #789 is in closed state with merge_commit_sha 3d0c13fa5a756ff94441dc57cf4e74318f45ba41, merged_at 2026-07-21T21:40:03-05:00, head aa4fe1cc7bd2d6f07ea35775a5c5292d94a938e0. Issue #787 is in closed state and carries no status:pr-open label.
Local verdict/state: reconciler cleanup phase authorized via gitea_authorize_reconciliation_cleanup_phase (delete_capability_verified: true). Two retained worktrees removed. Source branch fix/issue-787-kill-segment-separators retained at aa4fe1cc on both the remote and locally.
Latest known validation: gitea_assess_master_parity reports in_parity: true, stale: false, restart_required: false, startup_head == current_head == 3d0c13fa5a756ff94441dc57cf4e74318f45ba41. gitea_assess_terminal_label_hygiene clean=true across 427 issues, residual_count 0. aa4fe1cc proven an ancestor of prgs/master.
What changed:
Removed local worktrees branches/merge-pr-789 and branches/review-pr789-aa4fe1cc. Both were clean, detached at aa4fe1cc, and contained in master. Snapshot diff confirmed exactly two removals with zero other entries added or changed; branches/ directory count 50 to 48, registered worktrees 43 to 41.
The MCP runtime was restarted through the sanctioned client reconnect path after the control checkout advanced to 3d0c13fa, restoring exact parity. No process was killed.
The only Gitea API mutation performed across this reconciliation is this audit comment.
What is blocked:
Blocker classification: process/rule blocker
gitea_cleanup_merged_pr_branch re-run on the restarted runtime returns the same verdict: its own assessment reports safe_to_delete: true, remote_branch_exists: true, empty block_reasons, recommended_action: delete_remote_branch, yet it fail-closes with blocker_kind: active_branch_ownership, blocking_categories: ["worktree_binding"]. The sole obstruction is that branches/fix-issue-787-kill-segment-separators still has the target branch checked out. That worktree is classified active_issue_work with preserve: True by the canonical snapshot because the durable #787 issue lock is live by time: work_lease.created_at 2026-07-22T01:37:57Z, work_lease.expires_at 2026-07-22T05:37:57Z, owner pid 52938 dead. Reconciliation stopped rather than removing a worktree the canonical workflow marks for preservation.
Who/what acts next:
Next actor: user
Required action: after 2026-07-22T05:37:57Z, when the #787 work lease lapses, or once it is released through its sanctioned owner path, remove branches/fix-issue-787-kill-segment-separators and re-run gitea_cleanup_merged_pr_branch for PR #789, then delete the local branch.
Do not do: do not hand-edit the issue lock file, do not remove the preserved worktree while its lease is live, do not touch branches/issue-681-preserve-wip or any unrelated artifact, and do not kill MCP daemon processes.
Canonical Issue State
STATE:

WHO_IS_NEXT:
user
NEXT_ACTION:
After the #787 work lease lapses at 2026-07-22T05:37:57Z (or is released through its sanctioned owner path), remove the worktree branches/fix-issue-787-kill-segment-separators, re-run gitea_cleanup_merged_pr_branch for PR #789 to delete the remote branch fix/issue-787-kill-segment-separators, verify verified_absent: true, then delete the local branch of the same name.
NEXT_PROMPT:
FINISH POST-MERGE RECONCILIATION FOR PR #789 (Scaled-Tech-Consulting/Gitea-Tools, issue #787).
Everything else is complete and verified. One artifact set remains: the source branch
fix/issue-787-kill-segment-separators, at aa4fe1cc7bd2d6f07ea35775a5c5292d94a938e0 on the
remote and locally, plus its worktree branches/fix-issue-787-kill-segment-separators.
Blocker recorded by the prior cycle: gitea_cleanup_merged_pr_branch assessed
safe_to_delete=true, remote_branch_exists=true, block_reasons=[] and still fail-closed with
blocker_kind=active_branch_ownership / blocking_categories=["worktree_binding"], because that
worktree holds the branch under the durable #787 issue lock (owner pid 52938 dead,
work_lease.expires_at 2026-07-22T05:37:57Z). The canonical snapshot classifies the worktree
active_issue_work with preserve=True while that lease is live.
Preflight as prgs-reconciler:
- load the workflow; confirm identity sysadmin / prgs-reconciler, role reconciler
- gitea_assess_master_parity must show startup_head == current_head == 3d0c13fa5a756ff944
41dc57cf4e74318f45ba41, stale=false, restart_required=false
- re-read ~/.cache/gitea-tools/issue-locks/prgs-Scaled-Tech-Consulting-Gitea-Tools-787.json
and confirm work_lease.expires_at has actually passed; do not assume it from the clock
- re-capture the branches snapshot and confirm the worktree is no longer preserve=True
- confirm the worktree is clean and that git diff 9e89efc prgs/master is empty
Then:
git -C /Users/jasonwalker/Development/Gitea-Tools worktree remove \
branches/fix-issue-787-kill-segment-separators
whoami -> resolve_task_capability(cleanup_merged_pr_branch) -> gitea_cleanup_merged_pr_branch

confirmation=<copy the exact value of the expected_confirmation field that the same tool

worktree_path=<any surviving path under branches/>
verify verified_absent=true, then:
git -C /Users/jasonwalker/Development/Gitea-Tools branch -D fix/issue-787-kill-segment-separators
Do not hand-edit the lock file. Do not touch branches/issue-681-preserve-wip or any unrelated
branch, worktree, lock, lease, issue or PR. Do not kill processes.
WHAT_HAPPENED:
Preflight proved identity sysadmin / prgs-reconciler, role reconciler, and workflow skills/llm-project-workflow/workflows/review-merge-pr.md hash 263d0a6cb8a6 with a clean session boundary. PR #789 state, its head, its merge commit and its parents (35e94e107c32 plus aa4fe1cc7bd2), prgs/master, the closed state of Issue #787, and ancestry containment were verified live. The comment-backed merger adoption lease from comment 13848 (session 79158-9d38efff1e7c, adopted from reviewer session 17962-46269707ca04 / comment 13843) reached its TTL at 2026-07-22T02:49:34Z, so gitea_cleanup_post_merge_moot_lease returned lease_moot: false and cleanup_allowed: false, reporting that the PR has reached a terminal state and no active reviewer lease remains, so there was nothing to clean and no marker was posted. The control-plane DB holds zero leases for PR #789, and all four PR-789 session pids are dead (author 52938, reviewers 84153 and 17962, merger 79158). The cleanup phase was authorized and the two clean detached worktrees were removed. The source-branch deletion fail-closed on worktree binding, both before and after the runtime restart.
WHY:
The removed artifacts belonged only to the completed PR #789 lifecycle, so reclaiming them carried no risk to live work. The author worktree was preserved because the canonical snapshot marks it preserve: True under a work lease that has not yet lapsed. Its head 9e89efc is a sibling of the published head — same parent 6b58f04, same tree 9b12bc5f, and an empty diff against prgs/master — so no unpublished work exists there, but proving content containment does not by itself authorize removing an artifact the workflow marks for preservation, and releasing that lease belongs to its owner path rather than to a reconciler. The source branch therefore stays until the binding clears.

BLOCKERS:
Source branch fix/issue-787-kill-segment-separators retained on the remote and locally. gitea_cleanup_merged_pr_branch fail-closes with blocker_kind: active_branch_ownership and blocking_categories: ["worktree_binding"] because branches/fix-issue-787-kill-segment-separators holds the branch under the #787 issue lock, whose work_lease runs to 2026-07-22T05:37:57Z with a dead owner pid 52938. No other blocker remains: parity is exact, capability resolves, and the branch assessment itself reports safe_to_delete: true.

[THREAD STATE LEDGER] PR #789 post-merge reconciliation — worktree cleanup complete, source branch retained under an active worktree binding
What is true now:
- Server-side decision state: no review or merge decision state was changed by this session. PR #789 is in closed state with merge_commit_sha `3d0c13fa5a756ff94441dc57cf4e74318f45ba41`, merged_at `2026-07-21T21:40:03-05:00`, head `aa4fe1cc7bd2d6f07ea35775a5c5292d94a938e0`. Issue #787 is in closed state and carries no `status:pr-open` label.
- Local verdict/state: reconciler cleanup phase authorized via `gitea_authorize_reconciliation_cleanup_phase` (`delete_capability_verified: true`). Two retained worktrees removed. Source branch `fix/issue-787-kill-segment-separators` retained at `aa4fe1cc` on both the remote and locally.
- Latest known validation: `gitea_assess_master_parity` reports `in_parity: true`, `stale: false`, `restart_required: false`, `startup_head == current_head == 3d0c13fa5a756ff94441dc57cf4e74318f45ba41`. `gitea_assess_terminal_label_hygiene` clean=true across 427 issues, residual_count 0. `aa4fe1cc` proven an ancestor of `prgs/master`.
What changed:
- Removed local worktrees `branches/merge-pr-789` and `branches/review-pr789-aa4fe1cc`. Both were clean, detached at `aa4fe1cc`, and contained in master. Snapshot diff confirmed exactly two removals with zero other entries added or changed; `branches/` directory count 50 to 48, registered worktrees 43 to 41.
- The MCP runtime was restarted through the sanctioned client reconnect path after the control checkout advanced to `3d0c13fa`, restoring exact parity. No process was killed.
- The only Gitea API mutation performed across this reconciliation is this audit comment.
What is blocked:
- Blocker classification: process/rule blocker
- `gitea_cleanup_merged_pr_branch` re-run on the restarted runtime returns the same verdict: its own assessment reports `safe_to_delete: true`, `remote_branch_exists: true`, empty `block_reasons`, `recommended_action: delete_remote_branch`, yet it fail-closes with `blocker_kind: active_branch_ownership`, `blocking_categories: ["worktree_binding"]`. The sole obstruction is that `branches/fix-issue-787-kill-segment-separators` still has the target branch checked out. That worktree is classified `active_issue_work` with `preserve: True` by the canonical snapshot because the durable #787 issue lock is live by time: `work_lease.created_at 2026-07-22T01:37:57Z`, `work_lease.expires_at 2026-07-22T05:37:57Z`, owner pid 52938 dead. Reconciliation stopped rather than removing a worktree the canonical workflow marks for preservation.
Who/what acts next:
- Next actor: user
- Required action: after `2026-07-22T05:37:57Z`, when the #787 work lease lapses, or once it is released through its sanctioned owner path, remove `branches/fix-issue-787-kill-segment-separators` and re-run `gitea_cleanup_merged_pr_branch` for PR #789, then delete the local branch.
- Do not do: do not hand-edit the issue lock file, do not remove the preserved worktree while its lease is live, do not touch `branches/issue-681-preserve-wip` or any unrelated artifact, and do not kill MCP daemon processes.

NEXT_ACTION:
After the #787 work lease lapses at `2026-07-22T05:37:57Z` (or is released through its sanctioned owner path), remove the worktree `branches/fix-issue-787-kill-segment-separators`, re-run `gitea_cleanup_merged_pr_branch` for PR #789 to delete the remote branch `fix/issue-787-kill-segment-separators`, verify `verified_absent: true`, then delete the local branch of the same name.
NEXT_PROMPT:

FINISH POST-MERGE RECONCILIATION FOR PR #789 (Scaled-Tech-Consulting/Gitea-Tools, issue #787).
Everything else is complete and verified. One artifact set remains: the source branch
fix/issue-787-kill-segment-separators, at aa4fe1cc7bd2d6f07ea35775a5c5292d94a938e0 on the
remote and locally, plus its worktree branches/fix-issue-787-kill-segment-separators.
Blocker recorded by the prior cycle: gitea_cleanup_merged_pr_branch assessed
safe_to_delete=true, remote_branch_exists=true, block_reasons=[] and still fail-closed with
blocker_kind=active_branch_ownership / blocking_categories=["worktree_binding"], because that
worktree holds the branch under the durable #787 issue lock (owner pid 52938 dead,
work_lease.expires_at 2026-07-22T05:37:57Z). The canonical snapshot classifies the worktree
active_issue_work with preserve=True while that lease is live.
Preflight as prgs-reconciler:
- load the workflow; confirm identity sysadmin / prgs-reconciler, role reconciler
- gitea_assess_master_parity must show startup_head == current_head == 3d0c13fa5a756ff944
41dc57cf4e74318f45ba41, stale=false, restart_required=false
- re-read ~/.cache/gitea-tools/issue-locks/prgs-Scaled-Tech-Consulting-Gitea-Tools-787.json
and confirm work_lease.expires_at has actually passed; do not assume it from the clock
- re-capture the branches snapshot and confirm the worktree is no longer preserve=True
- confirm the worktree is clean and that git diff 9e89efc prgs/master is empty
Then:
git -C /Users/jasonwalker/Development/Gitea-Tools worktree remove \

verify verified_absent=true, then:

WHAT_HAPPENED:
Preflight proved identity `sysadmin` / `prgs-reconciler`, role reconciler, and workflow `skills/llm-project-workflow/workflows/review-merge-pr.md` hash `263d0a6cb8a6` with a clean session boundary. PR #789 state, its head, its merge commit and its parents (`35e94e107c32` plus `aa4fe1cc7bd2`), `prgs/master`, the closed state of Issue #787, and ancestry containment were verified live. The comment-backed merger adoption lease from comment 13848 (session `79158-9d38efff1e7c`, adopted from reviewer session `17962-46269707ca04` / comment 13843) reached its TTL at `2026-07-22T02:49:34Z`, so `gitea_cleanup_post_merge_moot_lease` returned `lease_moot: false` and `cleanup_allowed: false`, reporting that the PR has reached a terminal state and no active reviewer lease remains, so there was nothing to clean and no marker was posted. The control-plane DB holds zero leases for PR #789, and all four PR-789 session pids are dead (author 52938, reviewers 84153 and 17962, merger 79158). The cleanup phase was authorized and the two clean detached worktrees were removed. The source-branch deletion fail-closed on worktree binding, both before and after the runtime restart.
WHY:
The removed artifacts belonged only to the completed PR #789 lifecycle, so reclaiming them carried no risk to live work. The author worktree was preserved because the canonical snapshot marks it `preserve: True` under a work lease that has not yet lapsed. Its head `9e89efc` is a sibling of the published head — same parent `6b58f04`, same tree `9b12bc5f`, and an empty diff against `prgs/master` — so no unpublished work exists there, but proving content containment does not by itself authorize removing an artifact the workflow marks for preservation, and releasing that lease belongs to its owner path rather than to a reconciler. The source branch therefore stays until the binding clears.
RELATED_PRS:
PR #789 (merge commit `3d0c13fa5a756ff94441dc57cf4e74318f45ba41`, the target of this reconciliation); PR #786 (predecessor that landed #630 at `35e94e107c32`); PR #788 (unrelated, remains in open state on `feat/issue-610-live-remote-parity`, untouched).
BLOCKERS:
Source branch `fix/issue-787-kill-segment-separators` retained on the remote and locally. `gitea_cleanup_merged_pr_branch` fail-closes with `blocker_kind: active_branch_ownership` and `blocking_categories: ["worktree_binding"]` because `branches/fix-issue-787-kill-segment-separators` holds the branch under the #787 issue lock, whose `work_lease` runs to `2026-07-22T05:37:57Z` with a dead owner pid 52938. No other blocker remains: parity is exact, capability resolves, and the branch assessment itself reports `safe_to_delete: true`.

runtime_recovery_guard._SEGMENT_SPLIT_REsplits a compound command line so each simple command is classified on its own. The background-job separator&was missing from the alternation and a subshell wrapper( ... )was never stripped before tokenising, so_analyse_kill_segment— which inspects only the first command token of a segment — never reached the kill verb in either form. With no marker written, review, merge, close and completion mutations stayed reachable after a real daemon kill.Adding
&to a quote-unaware splitter, as the first head did, fixed those two forms but created a false-positive class. Review #497 measured three regressions against base35e94e10, all of which merely mention the canonical kill string:A false contamination marker fails review, merge, close and completion mutations closed and by design only a reconciler may clear it, so it is an operator-visible stall rather than a warning. Since the regressing string is the exact example this issue is written around, a doc line or commit message about #787 was itself a trigger.
Implementation
_iter_active()yields only the character positions where a shell metacharacter is syntactically active — outside single and double quotes, and not backslash-escaped — and_split_segments()separates only at those positions. This addresses the class, not the three named strings, and also retires the;and|false positives that predate this issue.&&and||are still consumed whole, so logical-separator precedence and the behaviour of;,|, newlines and standalone&are unchanged._strip_subshell()removes a trailing)only when it closes a leading(that the same call stripped, so balanced command substitution survives (kill $(pgrep -f myapp)is no longer mangled intokill $(pgrep -f myapp)._is_redirection()keeps2>&1,>&2and&>logfrom being read as background separators;a 2>&1previously split into['a 2>', '1'].The last two are the reviewer's informational F3 observations. Neither changed a verdict at the rejected head, and neither is required to close #787 on its own; they are corrected here only because F1 required reworking the same splitter, which is where the reviewer asked for them to be tightened or commented.
Out of scope and untouched, as the issue directs: the contamination model, the gated-task set, the marker lifecycle, and the reconciler-only clearing path. No widening of detection to automatic ingestion from other tools.

Scope examined
Diff versus base master
35e94e107c32cfdc4b9ab9a95cb4e94df94077d4touches exactly two files, 103 insertions, 3 deletions:runtime_recovery_guard.py—_SEGMENT_SPLIT_REwidened, new_strip_subshell(), applied in_split_segments().tests/test_issue_630_runtime_recovery_guard.py— new cases only.No unrelated refactoring. The contamination model, gated-task set, marker lifecycle, and reconciler-only clearing path are untouched. Scope discipline for #787 holds.
Behaviour was examined by reading the diff at the pinned head in a dedicated detached worktree, by direct in-process classification of 28 command strings against both the head and a clean-base copy of the guard, and by running the test suites at both commits.
What is correct
Both previously missed forms are genuinely fixed. Reproduced independently at the pinned head:
Same two strings against the clean-base copy of the guard reproduce the defect exactly as issue #787 records it (contamination=False, reason_class=None), so the change is the cause of the improvement.
Operator precedence survives the widened alternation.
_split_segmentsreturns['a', 'b', 'c']fora && b || cand['a', 'b']fora & b;true && false || pkill -f mcp_server.pystill classifies as contamination andsystemctl restart myapp && echo okdoes not.Existing direct-command behaviour is preserved:
pkill -f mcp_server.py,pkill -f gitea_mcp_server,killall mcp_server,sudo pkill -f mcp_server.py, the&&compound, and the broadpkill -f pythonsweep all keep their prior outcomes.pkill -u mcpuser -f myappstays non-contaminating and unambiguous,ps aux | grep mcp_serverstays a non-kill,kill 31337stays ambiguous and non-contaminating, and benign background jobs (npm run dev & sleep 2) are not flagged.The broader-failure claim is sound. Verified at both commits in separate worktrees, not taken on trust.
Findings
F1 — BLOCKING (correctness + coverage). Splitting on
&creates a new false-positive class, and the one test that guards it is written so it cannot catch the case.The splitter is quote-unaware. Adding
&therefore makes any quoted text containing an ampersand followed by a kill verb classify as contamination. Measured, head versus clean base:Three of these are regressions introduced by this head. The
;and|rows show the underlying quote-unawareness predates this PR, so the class is not new — but this change extends it to the one separator that appears in the canonical example string, and that string is the subject of this very issue. Any commit message, doc line, or grep that quotessleep 1 & pkill -f mcp_server.pynow classifies as a manual daemon kill.Why this is blocking rather than cosmetic: issue #787 scope item 4 names "a commit message quoting the kill string" as a case that must keep its non-contaminating outcome, and AC5 requires test coverage for it. The PR adds
test_commit_message_quoting_the_kill_string_is_not_a_kill, but the string it quotes omits the ampersand, so the test passes while the very form the issue is about regresses. The named case is nominally covered and actually unprotected.Consequence when triggered:
gitea_record_daemon_process_kill_attemptwrites a durable contamination marker, and_enforce_runtime_recovery_contamination_gatethen fails review, merge, close and completion mutations closed. By design a worker session cannot clear it — only a reconciler can. A false marker is therefore an operator-visible stall, not a warning.Blast radius today is bounded:
assess_recovery_commandhas exactly one production consumer,gitea_record_daemon_process_kill_attempt, so the marker is written only when a session explicitly calls that tool. It is not yet wired to arbitrary command strings. That containment is exactly what the issue's own deferred follow-up proposes to remove by feeding the classifier fromgitea_record_pre_review_commandandgitea_assess_gitea_operation_path. Landing this false-positive surface first and that wiring later would turn a latent defect into a live one.Required change, either of:
;and|false positives, so the guard strictly improves.Either way AC5 needs a case that quotes the full
sleep 1 & pkill -f mcp_server.pystring inside a non-executing command and asserts contamination is False.F2 — MINOR (evidence accuracy). The stated test counts in the PR body do not match the head.
The body states the file "held 46 cases before this change" and that "9 were added". Counted at both commits, and confirmed by collection: base
35e94e1047 passed, head6b58f0455 passed. Eight test functions are added, not nine, and the prior count was 47, not 46. The suites themselves pass as claimed; only the arithmetic in the narrative is wrong. Please correct the body so the record is accurate.F3 — INFORMATIONAL.
_strip_subshelland the widened split both treat shell syntax loosely._strip_subshellremoves a trailing)unconditionally, sokill $(pgrep -f myapp)becomeskill $(pgrep -f myapp. No classification changes today because the remaining text still carries or lacks the daemon pattern, but the helper mangles balanced command substitution as a side effect of stripping an unbalanced wrapper. Similarly the new&split turnsa 2>&1into['a 2>', '1']. Neither causes a wrong verdict in the cases tested; both are worth a comment or a tightened implementation if the splitter is reworked for F1.Test evidence
All commands were run by this reviewer with an absolute interpreter path, in the stated working directory. No repository file was edited.
Focused suite at the pinned head:
Focused suite at the clean base, separate detached worktree:
Broader suite comparison, non-destructive, two separate worktrees at the two commits:
The failing ids match one for one at both commits: six in
tests/test_commit_payloads.py, two intests/test_issue_702_review_findings_f1_f6.py, one intests/test_mcp_server.py::TestPreflightVerification, one intests/test_post_merge_moot_lease.py, one intests/test_reconciler_supersession_close.py. The author's claim that these predate the branch is confirmed and they do not bear on this verdict.Classification probe:
AC4 (marker written for both new forms) is covered by the two new record-tool cases, which pass in the focused run above. This reviewer did not invoke the live record tool, because writing a real contamination marker would fail this session's own review mutation closed.
Verdict rationale
AC1, AC2 and AC4 are met. AC3 is met for the cases the issue enumerates literally. AC5 is not met: the commit-message case it names is covered only in a form that cannot exercise the new code path, and the head regresses that case for the exact string the issue is about. F1 is a correctness defect in the shipped behaviour, so the verdict is request_changes.

_analyse_kill_segment,classify_recovery_command,assess_recovery_command), the contamination model, the gated-task set, the marker lifecycle, and the reconciler-only clearing path are untouched. No widening of detection into other tools. Scope discipline for #787 holds.Disposition of review #497 findings
F1 (BLOCKING at
6b58f04) — RESOLVEDThe splitter is now quote-aware.
_iter_active()walks the string tracking single- and double-quote state and backslash escaping, yielding only positions where a metacharacter is syntactically active;_split_segments()separates only at those positions. This is the preferred remedy #497 named, and it addresses the class rather than the three measured strings.All three measured regressions are gone, and the two pre-existing
;/|false positives #497 documented are retired as well — so the head is strictly better than base on this axis, not merely better than the rejected head. Measured this session at all three commits:Every row where base reads True and the head reads False is a command that executes no kill at all under shell semantics — an escaped or quoted separator makes the text an argument, not syntax — so each is a false positive being retired, never a detection being lost.
AC5 coverage is now real.
F1_QUOTED_COMMANDSholds the full ampersand-bearing strings and is asserted twice: once against the classifier (test_quoted_ampersand_examples_from_review_f1_are_not_kills) and once against the marker-writing tool (test_record_tool_does_not_mark_a_quoted_mention_of_the_kill_string, assertingcontaminated is False,marked is False, and_load_runtime_recovery_marker(...) is None). The second assertion is the one that matters operationally, because the marker is what fails mutations closed. Single-quoted, escaped, and escaped-inside-single-quote forms carry their own cases.F2 (MINOR, evidence accuracy) — RESOLVED
The body now states 47 at base, 55 at the rejected head, 64 at this head, and says the rejected head added 8 cases rather than 9. Re-counted independently this session in three separate detached worktrees; the corrected figures are exact. Full-suite pass counts corroborate the arithmetic: base 4173 passed versus head 4190 passed, a difference of 17, matching 64 − 47.
F3 (INFORMATIONAL) — RESOLVED
_strip_subshellnow removes a trailing)only when_closes_leading_paren()proves it closes a(this call stripped, tracking nesting over active characters.kill $(pgrep -f myapp)is returned intact, and(kill $(pgrep -f myapp))unwraps tokill $(pgrep -f myapp)with the substitution balanced. An unmatched leading(is still dropped alone, which is required because splitting a wrapped compound orphans the opening half._is_redirection()keeps2>&1,>&2and&>logout of separator position.Segmentation properties verified
Verified by direct calls to
_split_segmentsat the pinned head, not inferred from the tests:The last eight rows are cases the diff does not name and the tests do not assert, chosen to test generality rather than the reported examples; each matches shell semantics.
echo "x"&pkill ...andecho a\ & pkill ...are the important ones: quote-awareness does not make a separator inert merely because quoting appears earlier in the line, so the fix suppresses false positives without opening an evasion path.True-positive reproductions at the pinned head
All required forms classify as contamination with
reason_class=manual_daemon_kill(broad sweep asbroad_process_kill), reproduced this session:echo 'a\' & pkill -f mcp_server.pyis the sharp case: POSIX gives a backslash no escaping power inside single quotes, so the quote closes and the&is genuinely active. The head detects it, which shows the quote handling is a faithful shell model rather than a blunt "ignore anything near a quote" rule.No-false-positive cases, unchanged at all three commits
Marker-creation proof
assess_recovery_commandstill has exactly one production consumer:gitea_mcp_server.py:15980, insidegitea_record_daemon_process_kill_attempt. Verified by repository-wide search at the pinned head forassess_recovery_command,classify_recovery_commandandbuild_contamination_recordoutsidetests/. That consumer writes a marker only underif contaminated and mark:(gitea_mcp_server.py:15990), wherecontaminatedrequires classifier contamination and absent operator authorization. That file is not in this diff, so the marker lifecycle is unchanged; the head narrows what reaches the marker rather than changing when a marker is written. The record-tool tests assert marker creation for both newly detected forms and absence of a marker for all three quoted mentions.Test evidence
All commands run by this reviewer with an absolute interpreter path, in the stated working directory. No repository file was edited. All three worktrees are session-owned, detached, and were clean before and after every run.

Validation failure history
The full suite at the pinned head exited 1 with 11 failing tests. No rerun was performed and no failure was made to disappear; the failures are dispositioned by the pre-merge baseline comparison below rather than by retry.
tests/test_commit_payloads.py— 6 failures (test_commit_files_content_plain,test_commit_files_local_path,test_commit_files_multiple_sources_blocked,test_commit_files_outside_scope_blocked,test_commit_files_traversal_blocked,test_commit_files_workspace_path)tests/test_issue_702_review_findings_f1_f6.py— 2 failures (TestF1RecoveryBeforeTerminalProbe::test_removed_worktree_recovers_before_probe,TestF2PreflightPathVerification::test_preflight_and_mutation_context_agree_on_dead_binding)tests/test_mcp_server.py::TestPreflightVerification::test_declared_clean_task_worktree_ignores_control_checkout_violation— 1 failuretests/test_post_merge_moot_lease.py::TestAcquireToolRefusesMergedPR::test_acquire_tool_fails_closed_on_merged_pr_without_posting— 1 failuretests/test_reconciler_supersession_close.py::TestReconcilerSupersessionMcpTool::test_tool_posts_comment_and_closes_superseded_pr_issue— 1 failureSuspected cause: host/workspace-state dependent preflight and commit-payload fixtures, unrelated to shell segmentation. Reproduced: yes, deterministically. Evidence that they are not caused by this change: none of the five modules imports or exercises
runtime_recovery_guard, and the identical set fails on the pre-merge base commit with this change absent.Pre-merge baseline proof
The comparison was run as a full suite at both commits, not only on the five affected modules, so the equivalence claim rests on the whole surface. The baseline commit is the pre-merge base of this branch, not post-merge master:

The 17-test pass-count difference (4173 to 4190) equals the focused-suite delta (47 to 64), so the head adds tests and removes none. The author's claim that the same 11 failures reproduce on clean base is confirmed, and confirmed on a wider basis than the author measured.

Merge capability (
merge_pr/gitea.pr.merge) and branch-delete capability (gitea.branch.delete) are both absent from this profile and neither was attempted.Findings and severity
No blocking findings. No correctness, safety, scope or coverage problem remains. Two informational observations, neither a regression and neither in scope for #787:
echo "oops & pkill -f mcp_server.pyclassifies as no kill. This is documented in the_iter_activedocstring and matches the shell, which rejects such a line as a syntax error rather than running its tail. The classifier's only consumer receives a command string a session voluntarily self-reports, so a syntactically invalid line is not a route by which a real kill escapes an honest report.{ pkill -f mcp_server.py; }andsh -c 'pkill -f mcp_server.py'both classify as no kill. Measured at base and at this head, identical at both, so this predates the branch and is not a regression. Issue #787 names only the subshell wrapper, and widening the tokenizer further belongs with the deferred follow-up that would feed the classifier automatically from other tools.Verdict rationale
Issue #787 acceptance criteria, each checked against the pinned head this session:
sleep 1 & pkill -f mcp_server.pyclassifies as contamination with reason classmanual_daemon_kill.(pkill -f mcp_server.py)classifies as contamination with reason classmanual_daemon_kill.pkill -u mcpuser -f myappstays non-contaminating and unambiguous;kill 31337andkill $(pgrep -f myapp)stay ambiguous and non-contaminating.The remediation is a genuine class fix rather than a patch over the three reported strings: it is expressed as shell syntax rules, it generalizes to cases neither the diff nor its tests name, and it retires two false positives that predate this issue. No true positive was lost anywhere between base and this head. The full-suite failures are proven baseline-equivalent on a whole-suite basis. Findings F1, F2 and F3 are each resolved, and no material regression was found, so the verdict is approve.

WHAT_HAPPENED:
An independent reviewer that did not author or remediate this work examined it at head
aa4fe1cc7bin a dedicated detached worktree, read the full two-file diff, exercised the segmentation scan directly on 22 syntax cases beyond those the diff names, classified 47 command strings against this head, the rejected head6b58f04and clean base35e94e10, and ran the focused suite at all three commits plus the full suite at this head and at base. The quote-aware splitter resolves review #497 finding F1 for the class rather than the reported examples, removes two false positives that predate the issue, loses no true positive, and finding F3's subshell and redirection defects are corrected; the corrected test counts required by F2 match the head exactly.WHY:
A false contamination marker fails review, merge, close and completion mutations closed and only a reconciler may clear it, so the false-positive class that made review #497 blocking had to be closed as a class before this change could land. It is, and the detection required by issue #787 is intact.

The control-plane DB holds zero leases for PR #789, and all four PR-789 session pids are dead (author 52938, reviewers 84153 and 17962, merger 79158). The cleanup phase was authorized and the two clean detached worktrees were removed. The source-branch deletion fail-closed on worktree binding, both before and after the runtime restart.WHY:
The removed artifacts belonged only to the completed PR #789 lifecycle, so reclaiming them carried no risk to live work. The author worktree was preserved because the canonical snapshot marks it
preserve: Trueunder a work lease that has not yet lapsed. Its head9e89efcis a sibling of the published head — same parent6b58f04, same tree9b12bc5f, and an empty diff againstprgs/master— so no unpublished work exists there, but proving content containment does not by itself authorize removing an artifact the workflow marks for preservation, and releasing that lease belongs to its owner path rather than to a reconciler. The source branch therefore stays until the binding clears.RELATED_PRS:
