Full spec on Linear FAFF-328. + +*Trial spec for FAFF-328. Audience: the trial agent and human reviewers. It designs and executes the bounded live-run trial ADR-0039 names as the outstanding evidence — a genuine mid-run derailment → subtractive correction → resume — and records a confirm/narrow/fail of the provisional GO.* + +## 1. WHY — Problem and Principles + +**The load-bearing idea:** ADR-0039 admitted Channel A on fixture evidence — pure-function probes over synthetic ledgers. What fixtures cannot prove is the mechanism under real run dynamics: the actual orchestrator authoring a correction from a real derailment verdict, a real abort-resume across dispatch boundaries, and a re-dispatched build honouring a narrowed mandate while the run's other governance (budget, run-done, runcheck) stays coherent around it. This trial exercises exactly that once Channel A carries genuine production authority, and records the verdict where the GO lives. + +**Problem statement.** ADR-0039's GO is explicitly provisional: "Live-run validation is an outstanding evidence item, not a settled claim." FAFF-326 ships Channel A and FAFF-325 ships the trust channel, but nothing exercises the composed system on a real derailed run. Until this trial records its outcome, every consumer of the GO — the `correct` rung, any future signal-widening — rests on fixtures. + +**Design principles.** + +- **Live means live.** The trial runs with genuine asserted integrity (FAFF-325 in production posture) — never the pure-function test seam. A seam-injected "live" run is fixtures wearing a costume and cannot discharge the caveat. +- **The trigger may be seeded; the dynamics must be real.** The provisional caveat doubted run dynamics, not trigger provenance. A deliberately thrash-prone trial issue inside an otherwise production-shaped run is admissible; synthetic ledgers or replayed events are not. +- **Observe, never patch.** The trial changes no shipped behaviour and hot-fixes nothing mid-run. A defect found routes out as a filed ticket and shapes the verdict; the first result always gets recorded. +- **A narrow or fail is a complete deliverable.** The spike house shape (ADR-0029 / ADR-0039 precedent): the recorded decision is the outcome, whichever way it goes. + +**Reference context.** + +| System | Relevance | +|---|---| +| `docs/adr/0039-…gated.md` | The provisional GO this trial discharges; the verdict lands here | +| FAFF-326 spec (its tracker thread, comment 23ecd6d3) | The Channel A contract surface the trial exercises: `faff corrective author/check`, the `correct` rung, `corrective-authored`/`corrective-consumed` events, `BuildDispatch.constraints` | +| FAFF-325 spec (its tracker thread) | The attestation signal that makes authority genuinely available | +| `plugin/skills/faff/bin/lib/sentry.js` + `test/sentry.test.mjs` | The fixture evidence base the trial's checkpoints compare against | +| `plugin/skills/faff-beep-boop/SKILL.md` + both concurrency executors | The acting sites: between-units consult, dispatch-boundary corrective check | +| `docs/specs/2026-07-03-FAFF-278-sentry-2-corrective-intervention-authority-model-design.md` | The spike whose pass-3 probe defined the fixture baseline | + +**Scope statement.** The final slice of the Sentry-2 lineage: FAFF-278 (decision) → FAFF-373 (fail-safe) → FAFF-325 (trust) → FAFF-326 (mechanism) → this trial (live evidence). + +## 2. OUT OF SCOPE + +- **Building or fixing Channel A** — FAFF-326. A mechanism defect the trial finds is filed as a ticket, recorded in the verdict, never hot-fixed mid-trial. *Extension point:* the TrialRecord's `defects_filed` list. +- **The integrity mechanism** — FAFF-325. The trial consumes its asserted state; it never re-tests forgery resistance (FAFF-325's own ACs own that). +- **Fleet supervision** — FAFF-327; this trial is per-run, single-issue. +- **Widening `correct` beyond `fix-review-thrash`** — the trial's evidence is the input to that future conscious edit (named in FAFF-326's design rationale); the widening itself is a new ticket. +- **Re-examining detection un-subvertability under shared fs** — FAFF-324. + +## 3.

The GO lapses to Channel D pending redesign — ADR-0039's own revisit trigger. + +## 4. HOW — Behavior + +**Approach.** No new production surface ships. The ticket delivers a trial runbook + seed materials, the executed trial, the committed TrialRecord, and the ADR verdict entry. One bounded procedure: + +``` +PROCEDURE live_trial: + 0. Preflight (any failure → the trial does not run): + a. faff corrective-integrity --json → asserted:true in the trial container + b. lights-out capability flag corrective_authority: available + c. corrective CLI region + correct rung present (validate Assumptions below) + 1. Seed: create the trial issue (clearly titled "[trial]", labelled per runbook), spec engineered + to iterate fix→review without shipping; sentry thresholds stay production-default + 2. Launch: human initiates the bounded run (the invocation is the authorization); + queue = trial issue + small benign remainder; budget ceiling per runbook + 3. Observe: capture checkpoints 1–9 from run artifacts (events.jsonl, run-ledger.json, + corrective/, dispatch logs, the trial PR diff) — read-only while the run is live + 4. Teardown: close/clean the trial issue, branch, PR, worktree; remove any overrides + 5. Record: commit the TrialRecord; write the ADR verdict entry; file any defects +``` + +**Edge cases.** + +- **Trip doesn't fire** (the seed iterates but stays under-threshold within budget): one bounded re-run is sanctioned with the thrash threshold tightened via config; `seeding.thresholds_overridden: true` is recorded and the verdict's claim narrows to "confirmed under tightened threshold". More than one re-run → stop and record the outcome as `narrow` with the seeding gap named. +- **Authority not asserted at preflight** → the trial is blocked, not run: a channel-D-only run cannot discharge the caveat. +- **Mechanism defect mid-trial** (e.g. `corrective author` rejects a valid input) → record the checkpoint fail, file the defect, complete teardown, compute the verdict per the semantics — never hot-fix and silently re-run. + +**Failure modes.** + +- **Seeded trigger unrepresentative** — the trip fires only via a pathological seed or non-default thresholds. *How you'd know:* the `seeding` disclosure says so. *What it means:* the verdict's claim narrows to the exercised conditions; a natural-derailment observation stays named as future evidence in the record. +- **Observer effect** — trial-only config distorts the dynamics under test. *How you'd know:* the effective-config diff recorded in `seeding.overrides`. *What it means:* every non-seeding knob stays production-default; overrides beyond the thrash threshold invalidate a `confirm`. +- **Surface drift** — FAFF-326's build diverged from its spec (renamed flags/paths). *How you'd know:* preflight 0c fails against the runbook's commands. *What it means:* rebind the runbook to the shipped surface before the trial; behavioural divergence triggers a refresh of this spec first. + +**Anti-pattern:** injecting `asserted:true` at the pure-function seam to run the trial early. Why: it re-proves the fixtures, not the trust channel — the caveat stays undischarged while looking discharged. + +**Anti-pattern:** skipping teardown because the trial run "was expendable".

DESIGN DECISION RATIONALE + +- **Seam-injected early trial vs live trusted-path trial?** Early is runnable before FAFF-325; live waits for the chain. **Chosen:** live trusted-path only — the seam re-proves fixtures; the caveat is precisely about the composed real system. The tracker chain (this ticket blocked by FAFF-326, which needs FAFF-325 for authority) encodes the wait. +- **Natural vs seeded derailment?** Natural is unschedulable and unbounded; seeded is bounded but mildly artificial. **Chosen:** a seeded trial issue in an otherwise production-shaped run — production-default thresholds first, one threshold-tightened re-run as the fallback, both disclosed in the record. Trigger provenance was never the doubt; boundedness is the ticket's own framing. +- **Trial environment — the faff repo vs a SUT repo?** **Chosen:** the faff repo via the standard lights-out runbook, with a clearly-marked trial issue and mandatory teardown — the GO governs faff's own production runs, so the trial runs where the GO applies; a SUT run would interpose an unrepresentative environment layer. +- **Execution mode — autonomous graft vs human-initiated window?** **Chosen:** a human-initiated trial window (the run invocation is the human authorization — the FAFF-278 human-supervised spike precedent), with agent-executed capture and recording. Consequence: an autonomous graft may prepare the runbook and seed but parks at the launch step with cause "trial window needs human launch" — expected and by design. +- **Where does the verdict land?** A new ADR vs an amendment. **Chosen:** on `confirm`, a dated "Live-run validation outcome" entry appended to ADR-0039's Consequences (the caveat and its discharge live together); on `narrow`/`fail`, a short new ADR superseding the GO boundary, cross-referenced from ADR-0039 — a changed decision earns its own record. + +## 7. OPEN QUESTIONS AND ASSUMPTIONS + +**Open Questions.** None — the trial's genuinely open item (does the GO hold?) is the deliverable, not a spec punt (the FAFF-278 precedent: method closed; the answer is the recorded output). + +**Assumptions.** + +- **Assumes:** FAFF-326 is built and merged per its spec (corrective CLI region, `correct` rung, both corrective events, `BuildDispatch.constraints`). *Validate:* the corrective region is registered (`faff corrective check` exits usage, not unknown-region); the consciously-extended AC6 guard is green in `test/sentry.test.mjs`. Absent → park (this ticket is tracker-blocked on it anyway). +- **Assumes:** FAFF-325 is shipped and the trial container genuinely asserts integrity. *Validate:* `faff corrective-integrity --json` returns `asserted:true` inside the trial environment; the lights-out banner shows `corrective_authority: available`. Absent → the trial is blocked (edge case above), even if this ticket's tracker edge has cleared. +- **Assumes:** the between-units consult and the `correct` interrupt row are live at the acting sites (beep-boop + both concurrency executors run `corrective check` at dispatch). *Validate:* the three SKILL.md acting sites named in FAFF-326's DONE carry the wiring. +- **Assumes:** the command/flag/path names in the checkpoint table match the shipped FAFF-326 surface at trial time. *Validate:* re-read FAFF-326's merged spec + PR before the trial; mechanical renames update the runbook, behavioural divergence triggers a refresh of this spec. + +## 8.

The premise holds. + +## Methodology critique + +Methodology: faffter-dark-methodology-agile-delivery + +- **Right-sized? (principle 4)** — No issues. One bounded trial plus its record: a 1–2 day unit once unblocked; runbook, execution, and record always ship together (an unexecuted runbook discharges nothing). +- **Workstream fit? (principles 1 + 5)** — No issues. "T3 — supervision stands alone" is outcome-named, and this is its evidence-closing increment — explicitly named by ADR-0039 and by FAFF-326's OUT OF SCOPE. +- **Deps surfaced? (principle 6)** — One finding. What's there: the ticket is tracker-blocked only by FAFF-326, but the trial's preflight equally load-bears on FAFF-325's asserted state — today reachable only transitively (FAFF-325 → FAFF-326). Why it matters: FAFF-326's spec explicitly allows shipping gate-degraded ahead of FAFF-325, so this ticket could unblock in the tracker while its preflight still fails. What to do: draw the direct FAFF-325 → blocks → FAFF-328 edge so tracker-unblocked equals actually-runnable (prep is drawing this edge with the promotion; the preflight Assumes is the runtime backstop either way). +- **Risk profile? (principle 7)** — No issues. The trial IS the de-risking step for the `correct`-rung lineage; its own risks (unrepresentative seed, observer effect, surface drift) are named as failure modes with mandatory disclosures in the record. + +confidence: high + +```faff-contract:spec-readiness +{ "confidence": "high", + "decisions": [ { "marker": "chosen" }, { "marker": "chosen" }, { "marker": "chosen" }, { "marker": "chosen" }, { "marker": "chosen" }, { "marker": "assumes" }, { "marker": "assumes" }, { "marker": "assumes" }, { "marker": "assumes" } ] } +``` + +## Spec review + +spec-review: approve + +Single-pass spec review (faffter-noon-spec-review; lenses fired per the change-surface cost-gate: all four — unclassified docs/trial surface, fail-safe; mode single-pass, level L3, appetite high). Zero objections: + +- **architectural** — no new production surface; the trial composes shipped precedents (ADR-0010 blast-radius boundary, the ADR-0029/0039 spike-deliverable shape); preflight fails closed (blocked, never channel-D-quietly); verdict-recording follows the house ADR convention (amend on confirm, supersede on narrow/fail). +- **infosec** — deliberate derailment is bounded by the container boundary, the run's budget ceiling, and a mandatory teardown step; the seed cannot ship (merge floor unweakened); seam-injected authority is explicitly anti-patterned, so the trial can't fake its own preconditions. +- **methodology** — the attached critique's single finding (missing direct FAFF-325 edge) is a tracker-topology gap, not a spec/slice defect; the remedy (edge drawn at promotion) plus the preflight Assumes backstop are already carried. Right-sized, right increment. +- **QA** — born-verifiable by construction: a checkpoint table with deterministic confirm/narrow/fail semantics, evidence pointers required per checkpoint, DONE mirrors the body 1:1. + +This verdict is retained alongside the spec's `confidence: high` line (the parent comment is the spec of record; treat `confidence: high` + `spec-review: approve` as its retained gate state).

Launch a bounded `faff lights-out` run from a cage-launched container carrying a well-formed + `FAFF_INTEGRITY_BOUNDARY` declaration in pid-1 environ, with: + - Queue = the seed issue + a small benign remainder (so the run isn't a single-ticket + spin-and-stop, matching "otherwise production-shaped run"). + - A budget ceiling per the repo's existing `budget.tokens` (`.faffrc.yaml`; currently 3B — + more than enough for one bounded trial; a human may set a tighter `--until`/local ceiling + for the trial window specifically). +4. Re-run preflight 0a/0b/0c from *inside* that container before treating the trial as started; + record the re-run results as the trial's real preflight (this runbook's §0 results are + prep-time evidence only, not a substitute). + +## 3. Observe + +Capture checkpoints 1–9 (table in the spec §3) from run artifacts as the run proceeds: +`events.jsonl`, `run-ledger.json`, `/corrective/`, dispatch logs, the seed ticket's PR +diff.
