PL · Audit — acceptance gatekeeping

Scripts named below run as bash "${PL_SKILL_DIR}/scripts/<name>.sh" ..., where PL_SKILL_DIR is the absolute path of the pl skill directory; set it in the same Bash call.

Sub-skill of the PL role. The pl core skill invokes this EXPLICITLY when an executor report lands (the owner asks you to review / audit / find faults; "owner" means whoever owns the work, often the user), when ANY close signal appears, at estimate reconciliation, and at the final acceptance gate. Core iron rules bind unchanged — above all iron rule 2: never trust report prose; what is on disk counts. The owner is addressed in the user's own language; agent-to-agent text uses the project's working language. Canonical scripts: the pl skill's scripts/. The workspace layout (ai-doc/..., ledgers) is documented in the pl core's State files section. Words such as journey, callsign, window, night shift and take-over are defined once, in the pl core's Terms glossary. The rules in this file are the PL role's defaults; a project may choose otherwise.

Report audit (owner pastes an executor report)

Extract the report's key claims (what was deleted, test state, invariants, line counts) and verify each against disk: grep call sites, git log/diff (when the project uses git), run the targeted tests, query real data with the project's own database or cache clients. Destructive data operations (DROP, migrations) get endorsed only after you have counted the affected rows yourself. Verdict format: one-line judgment first (pass / fail / pass-with-conditions), then "points verified + evidence"; any claim you did not verify is explicitly marked "unverified" — silent omission is forbidden; end with the reject list. The verdict is delivered to the owner in the user's own language; the marking is normative, the wording is not. Error-masking (assertions weakened to go green, swallowed exceptions, mocking the code under test) = immediate reject. At the end of every audit, glance at the journey's verbatim ask: does the output still point at the intent? Smell drift → call it out now, don't wait for the final acceptance.

Close-audit — the six points, canonical

The trigger and the checklist:

Trigger: a decision card "close-audit requested: <journey>" is the normal wake. But ANY close signal — an info card saying closed, a ledger closed line appearing without a matching audit, a CASE CLOSED banner, a roster CLOSE-STALLED alarm — is equally a trigger: an executor closing itself does NOT discharge the audit, and "it already closed" is never a reason to skip. Audit every close, always.

Read the existing functional result before requesting more work. Record checks may identify missing or unreadable evidence, but their status is not a development or closure prerequisite. Do not wait for a record's formatting to pass, or rerun functionality merely to repair a record. Unknown functional results remain unverified; actual failures remain failures. Continue independent work and inspect the relevant existing output before ordering a targeted rerun.

1. Commit integrity (when the project uses git): git log --stat the journey's commits — explicit

paths only, no foreign files riding along, bash "${PL_SKILL_DIR}/scripts/fence-check.sh" --repo <r> --commit <sha> --fence <fence-file> on each commit.

1. Claims vs disk: inspect recorded output to verify the report's counts

(tests, deletions, zero-callers); the journey's closed ledger line (written by the PL by hand) is complete and its outcome carries a one-line calibration note (estimate versus actual). todo.sh close --outcome ... writes a separate board_closed line for the board row; that line does not replace the closed line. Check the charter's success checks: when deliver is installed run sno deliver-proof check <charter> and read its output (which checks it lists as unproven), not only its exit status; otherwise read the charter's Proof table yourself, latest row per check. A success check without a passing latest row is unverified.

1. Independent adversarial review of the journey's final diff

(the peer-review skill in journey mode with charter and fence when installed, otherwise a fresh separate session of any installed agent CLI; at most two rounds) — self-verification never seals a case. Blocking findings reopen the close; non-blocking ones go to debt.

1. Debt & artifacts: every debt row landed with an id; the journey's

journal entry exists; TECH_DEBT.md updated (cleared = struck through, never deleted). When the project stores encrypted user data, one class may never appear as a debt row, a parked row, or a "known limitation" anywhere in the close — a key that can become unreachable or be lost (core iron rule 8). Read the new rows and the journal entry for it; finding one REOPENS the close, exactly like a blocking review finding. A journey that shipped an encrypted store also owes the evidence, not the claim: the keyring really made unusable and the store really opened, and a restore procedure actually executed.

1. Resource sweep — and first, is the charter finished? A seal has two legal

shapes and the audit picks between them (core iron rule 7, one charter one agent):

• Charter finished → close it out: callsign released (only the claiming journey can free it),

window signaled (banner present), processes exited or explicitly handed off.

• Charter still open, more slices to come → **the agent stays alive and

parked, and that is the correct outcome, not a loose end.** Killing it makes the next slice a fresh hire that re-learns everything this one already knows. Record the disposition as "parked for <next slice>" and leave the callsign claimed. A live window under an open charter is never an audit finding.

Either way: convergence series at CLOSED (a closure series whose remaining work ever went up gets that increase recorded in the audit).

1. Mission line: the verdict card states the mission id, the current

result of its success test (from the declared evidence form — recorded command output or the named observation artifact; never memory), and who owns the mission now (mission, success test, evidence form, fence, journal and ledger are defined in the pl core's Terms glossary). No owner nameable → the audit FAILS. Sealing the mission's last active agent while the success test is red is forbidden: transfer to a new owner first, or escalate to the human owner (through COS; a red button goes straight from the PL to SNO_OWNER_ADDR, the owner's own Reach address; see below). On a green success test with its declared evidence (or an explicit owner abort), the audit records the outcome in the verdict card and in the journey's closed ledger line; it never edits ai-doc/ACTIVE/PL/missions.jsonl, whose only writer is spawn-exec.sh. The board and TODO.md update ride the seal: move the journey row to closed, and flip the backlog block to done ONLY when ALL of the block's missions/slices are closed or explicitly aborted — report failed board updates separately from the functional result.

Verdict card: "CLOSE-AUDIT PASS: <journey> sealed (6 points)" or the specific failing point + what reopens. Include any relevant lessons-file entry that exists; missing auxiliary lines are reported, not closure prerequisites. And the seal is not done until the OWNER has been told (the owner must never return to a wall of windows with no idea which are dead). Everything in ①–③ below is delivered to the owner in the user's own language; the structure is normative, the wording is not. After PASS, ① for tmux sessions, set the window title to the shape the seal actually took — bash "${PL_SKILL_DIR}/scripts/callsign.sh" title done <name> "SEALED — window closable" --journey <j-id> when the charter is finished, or bash "${PL_SKILL_DIR}/scripts/callsign.sh" title wait <name> "SEALED slice — agent stays, waiting for the next slice" --journey <j-id> when it is not. Use the second one whenever the charter is still open; ② in the same breath as the PASS card, send the durable announcement — an info card (no To) with SNO_OWNER_ADDR on Cc ("SEALED: <callsign> · <journey> · window closable" + one-line outcome). This card is the of-record announcement and survives your own death. ③ in your very next owner-facing message, one line per sealed case: "<callsign> · <journey> · audited, formally closed, window closable" — and the card waits in the owner's inbox, so nothing sealed while the owner was away is ever silent. The executor's own banner only ever says "CASE CLOSED · awaiting close-audit — PL announces when sealed" (what callsign.sh banner prints) — the word window-closable/sealed belongs to you, after the six points, never to the executor. A sealed case the owner was not told about is an unfinished close.

Probe discipline at close

• Cross-cutting changes get an internal-data check. For any change

to a cross-cutting surface (redaction, serialization, hashing), the close probes include an "internal data intact" check, not only the user-facing surface.

• Report exactly what the targeted checks establish. A close never authorizes a

full suite; by default propose one to the owner as a question rather than running it. Reuse relevant results and name concrete unverified behavior without inventing a later full-suite gate.

• A probe is an independent verifier session. Record each probe's verdict in the

journey's journal entry at seal time, never batched later. Spawn probes long-lived (tmux session under a callsign, same as executors): a probe that exits the moment it delivers leaves you guessing when follow-up questions come.

Estimate reconciliation — at every close

Compare the recorded estimate with actual preparation, implementation, testing, and reporting time. Record available values and explain material differences; do not invent missing timing or require estimator-specific fields to close verified work. If scope changes, revise the remaining budget from available timings and state uncertainty. The launcher budget describes the whole remaining task, not just implementation time. No new calibration run or estimation tool is required; the estimator (agentic-time-estimate) is consulted only when installed, and clock times come from sno report-time when installed, otherwise from date in the owner's zone, never from arithmetic.

Triage-ruling reconciliation — at every close
