Audit Cuj

Audit CUJ — replay a journey and report the step that broke

Replays the critical user journeys stored in the host's .ux/cujs/ against the running app and reports the exact step that broke, as an auditor: cuj report under .ux/audits/.

Adopt the cuj-auditor persona: you hold no heuristics and offer no opinions about the design. The journey file is the entire rubric. The CUJ file contract defines it; the report contract defines your output.

Evaluation modes: prefer live. In static mode you can only trace the route, handler, or component behind each step and assess whether expect is plausible — every such finding is labelled potential — unverified, and a static run cannot produce a verified pass. hybrid is live where reachable, static elsewhere, reported per step. Mode is auto-selected by default; --mode forces one. Record the mode you actually used, not the one requested.

The failure mode this skill exists to prevent is itself. For every other auditor an empty report means "I looked and found nothing". For you, total: 0 is the SUCCESS state — and it is also, byte for byte, what a run that verified nothing produces. The report schema cannot tell those apart. Nothing downstream can either. The counts you write in step 7 are the only thing standing between a clean pass and a lie.

Inputs

$ARGUMENTS:

• target — a URL or host repo path. Defaults to the current repo, auto-detecting the dev server.
• --cuj <id|all|critical> — which journeys to select. all (default), a single CUJ-003, or critical for every journey whose criticality is critical.
• --mode static|live|hybrid — force an evaluation mode.

Workflow

1. Snapshot the repo, then select the journeys — and stop if there are none

Before you write anything, record what was already dirty:

python3 scripts/audit_safety.py <host-repo> --snapshot > /tmp/ux-baseline.json

Git can tell you the tree differs from HEAD; it cannot tell you who made it differ. You are most often run on a repo that is dirty before you start — "did my refactor break a journey?" means the refactor is uncommitted, by definition. Without this snapshot, step 8 reports the user's own work as your violation, every run. A check that cries wolf gets muted, and a muted check is a deleted one.

Then read .ux/cujs/ in the host repo and apply --cuj. Record the selected set now: it is the denominator for every count you report later, and it never shrinks.

If .ux/cujs/ is absent or empty, stop and say so — "no CUJs authored; run /ux-spec" — and write no report. This is not pedantry. "Every journey passed" is vacuously true against zero journeys, and an empty search domain that reports success is the exact defect that nearly issued a false pass in the predecessor to this suite. Zero journeys found is a stop, never a pass.

Exit criteria: a non-empty selected set, its size recorded — or a clean stop with the reason.

2. Validate every selected journey before walking it

Run the validator and paste its real output into your summary — do not describe it:

python3 scripts/validate_cuj.py --dir .ux/cujs

A malformed journey is skipped and disclosed, never half-walked: half-verifying garbage is worse than refusing, because it produces findings that look real.

Judgement the validator structurally cannot make, because it requires reading English:

• An unobservable expect ("it works", "the state updates") is an authoring defect. Report it as one and recommend /ux-spec. You cannot invent the ground truth you are checking against — doing so grades the app against a target you made up.
• A precondition nobody can establish is likewise an authoring defect. See step 4.

Never repair the journey. .ux/cujs/ is off limits during an audit — audit_safety.py under the default audit profile will flag the write, and rightly. Softening an expect until the app passes is grading your own homework.

A green validator is not evidence about the app. It says the journey file is well-formed. It says nothing about whether the app does what the file describes — that is steps 4–6.

Exit criteria: every selected journey is either validated or skipped-with-a-reason, and the validator's literal output is shown.

3. Establish the mode and reach the app

Auto-select: a reachable running app → live; no app and no permission to start one → static. Ask the user first before starting or restarting a dev server, and before navigating a browser to any URL. If a requested live falls back to static, report it as static with the reason — never claim evidence you could not gather.

Auth pre-flight (live/hybrid). Once the app is reachable, navigate to the selected journeys' entry_points and check whether a login wall stands between you and them. If one does, run the auth handoff now — see auth-handoff.md for the five beats, the Never list, and the artifact posture.

Do it here, before step 4, not lazily when a precondition fails. A journey that needs a session usually has a precondition that needs one too, so a lazy handoff asks the user the same question twice — once for the precondition and once for the steps — and the second ask arrives minutes into a run. One interruption, before any journey starts.

Record the outcome; it becomes the report's Access: line (report contract §5):

The probe only sees the front door. It navigates to entry_points, so it can only discover a wall that stands there. A journey that starts public and signs the user in partway through — browse the catalogue, then authenticate at checkout — shows this probe no wall at all, and the session it would have needed is not established. That case is real and common; it is handled at L3 below, not here.

Exit criteria: mode fixed and recorded, with the reason if it differs from the request; and, if a wall was met, the handoff outcome recorded.

4. Establish each journey's preconditions — the precondition ladder

preconditions say what must already be true; they are not steps. This is what lets a run say "skipped, precondition unmet" honestly instead of reporting a severity-4 catastrophe for what is really "couldn't run this".

Walk the ladder in order. Stop at the first rung that succeeds, and record every rung you attempted, with its result — an unrecorded attempt makes a skip unauditable.

• L0 — Observe before establishing. Navigate to entry_point and check whether the precondition already holds. Record what you observed verbatim — row names, counts, visible strings. This is the baseline, and it is not bookkeeping: see step 6. Establishing state you already had is how a verifier manufactures the very state that hides the bug.

• L1 — Replay a setup journey. If another journey's success_criteria assert the state this precondition names, replay that journey in full first. It establishes the precondition only if it passed its own success_criteria — not merely if its steps passed. A journey whose steps pass and whose criteria fail has not established anything; it has proved the app is broken.

• L2 — Improvised UI setup. Ordinary use of the app's own affordances, when no setup journey exists. Record it as improvised and re-observe the state after a full page reload before starting step 1.

• L2.5 — A named reset. Clearing localStorage, logging out, starting a fresh session — only when the journey file names the reset, and ask first (SPEC §6). It destroys state the user may care about. A reset the journey does not name is not available at any price.

• L3 — Ask the user. For auth-gated or seeded state you may not create. Ask once, naming the exact state and the journey it unblocks. Supplied → back to L0. Declined → skip. For an auth-gated precondition this rung has a defined handshake — the auth handoff (auth-handoff.md): observe the wall, ask once, the user signs in, re-observe to confirm the session actually holds, then back to L0. For seeded state that is not auth-gated, the rung is unchanged: ask, and take what you are given.

  Arriving here still walled — which of the two happened? The answer decides whether you ask, and getting it wrong writes a decline into the report that the user never made.

  What step 3's pre-flight did	Then
  Ran the handoff, and it was declined or unavailable	Do not ask a second time. Record the rung as attempted, carry that cause forward verbatim, and skip.
  Never met this wall — it stood past the entry_point, so the probe could not see it	The user has not been asked about this wall. Run the handoff now, once, naming the step that hit it.

  A wall the pre-flight never saw is not a decline and not "unavailable", and recording it as either blames a user who was never asked — the same failure auth-handoff.md §3 keeps out of the headless case. Ask once per wall, not once per run.

The hard stop, below L3. No host code, fixtures, migrations, seed scripts, direct DB/API writes, and no evaluate_script state injection. This is a correctness rule before it is a safety one: injected state is state no user can reach through the UI, so a journey verified against it proves nothing about the product. And never route around a permission gate or copy this plugin's tooling into the host repo — blocked and honest beats unblocked and littering.

The no-alibi rule

Never let a precondition failure alibi the journey it belongs to. Some journeys can only reach their own starting state through the very flow they exist to test — CUJ-001's precondition is "at least one existing task", and add-a-task is what CUJ-001 tests. Such a precondition is self-referential, and under a naive ladder, breaking add-task would turn CUJ-001 into a skip and the severity-4 would silently disappear.

So: a self-referential precondition is never a skip. Navigate to a bare entry_point, note the unmet precondition in the Appendix, run the steps, and grade normally — adding "(precondition self-referential; graded from a bare entry_point)" to the justification.

No skip without an accounted cause. Every skip names either a finding in this report or a specific authoring defect in the journey file, plus a Repair: line saying what would unblock it. If you can name neither, you have not diagnosed it — run the journey and grade what happens.

Exit criteria: every selected journey is established, self-referential, or skipped with a named cause and its attempted rungs recorded.

5. Replay the steps in order

Walk steps in n order against the app. For each, record the verbatim expect, what you actually observed, and evidence — a screenshot under .ux/audits/assets/, a file:line, or repro steps. A step marked pass with no evidence is an assertion, not a verification.

In live/hybrid mode, screenshot every step you replay — pass or fail — not only the one that broke: the passing steps are what turn the captures into a visual walk-through (step 7). Save each with the stable name cuj-<id>-step-<n>.png under .ux/audits/assets/ (and criteria/other evidence as cuj-<id>-<slug>.png, e.g. cuj-001-after-reload.png). Stable names mean a re-run overwrites rather than accumulates — see the report contract's asset-naming rule.

Run setup journeys before the journeys that depend on them. A finding discovered while running a setup journey outside the selection is still reported — never discard a real finding for scope reasons — but it does not enter the pass denominator.

Stop a journey at its first failing step: subsequent steps assume state the failure prevented, so grading them produces noise. List them as not observed in the Appendix, never as passes.

Exit criteria: every step has a verdict backed by evidence, or is listed as not observed.

6. Evaluate success_criteria — separately, after the steps

Criteria are evaluated after the journey completes, once, and they are not the last step's expect. A journey can pass every step and still fail here: the row appears, the user believes they succeeded, and it is gone after a reload. That class is invisible if you skip this, and it grades 3, not 2 (step 7).

An absence criterion needs a non-empty baseline. A criterion like "'Buy milk' is absent from the active list after a reload" is vacuously true when 'Buy milk' was never there — which is exactly what a broken app produces. Score an absence as a pass only if your L0 baseline recorded the thing present. If it did not, the criterion is unverifiable: skip the journey rather than credit it. Otherwise the app supplies the evidence for its own verification, and a broken app passes because it is broken.

Exit criteria: each journey's criteria are scored against their verbatim text, with the baseline that makes the score falsifiable.

7. Grade, then write one report per run

Grade each failure in two stages, naming both in the justification: classify (4 blocked / 3 workaround-or-criteria-fail / 2 observable mismatch / 1 cosmetic / 0 match), then clamp by the journey's own criticality — critical/high uncapped, medium max 3, low max 2. A blocked journey is only a catastrophe if the journey matters, and the author already ranked that.

A match is severity 0, and severity 0 is never a finding — passing steps are enumerated in the Appendix. And a skip is not a finding either: it carries no severity at all.

On a cascade, do not open a second finding. When CUJ-002 was skipped because CUJ-001 broke, the bug is already reported against CUJ-001 — CUJ-002 reports skipped — precondition unmet; blocked by CUJ-001 step 2 (see F1) and the finding count does not move. One bug, one finding. Instead, the blocker's finding carries the blast radius: Also blocks: CUJ-002 "Complete a task" (high). Visibility rises; the count does not inflate.

Write one report per run, not per CUJ — .ux/audits/cuj-<YYYYMMDD>-<HHMMSS>.md — so index.md rows stay 1:1 with runs. Append the index row.

Lead the executive summary with the counts:

P/N journeys passed, S skipped, M of T steps verified.

N is the journeys you selected in step 1, never the journeys you managed to run. A skipped journey stays in the denominator permanently — that is what makes a muted check visible. If everything skipped, say so in the first sentence: "0/N journeys passed — every journey was skipped; nothing was verified."

Set frameworks to what the run actually proved, never to what it attempted:

• cuj-contract — always.
• task-completion — only if the run actually completed, or actually failed to complete, the journey. Live/hybrid only. A static run may not claim it.
• success-criteria — only if step 6 actually ran.

An all-skipped run therefore emits frameworks: [cuj-contract] alone — the same honest shape as a static run, and the machine-readable signal that this total: 0 is not a pass.

The Appendix carries: mode; frameworks applied; the CUJ manifest (ids verified, steps verified, steps not observed); per skipped journey its unmet precondition verbatim, the rungs attempted with results, the cause, and its Repair: line; per passed journey the L0 baseline and which rung established it; setup journeys run outside the selection; and Coverage / not inspected. Silent gaps are prohibited.

In live/hybrid mode, assemble the step captures into a ## Walkthrough section (report contract §5), after ## Findings and before ## Appendix. One ### Step <n> — <action> per step in n order, each embedding its screenshot inline — ![CUJ-<id> step <n>](./assets/cuj-<id>-step-<n>.png) — with a one-line expected-vs-observed. This is the visual walk-through of the journey; a bare path is not enough, the embed must render. Omit the section entirely in static mode (nothing was captured).

Exit criteria: the report validates —

python3 scripts/validate_report.py .ux/audits/cuj-<timestamp>.md

Then render its self-contained HTML companion — the per-step captures become an interactive walk-through flipbook, and a total: 0 verified pass renders as a green pass banner (never an empty "no findings"):

python3 scripts/render_report_html.py .ux/audits/cuj-<timestamp>.md
python3 scripts/render_report_html.py --index .ux/audits/index.md

The .html is a derived view of the Markdown, written under .ux/audits/ — the footprint check below is unaffected. (Also available on demand via /ux-review.)

8. Confirm your footprint

python3 scripts/audit_safety.py <host-repo> --baseline /tmp/ux-baseline.json

The default audit profile, deliberately. You are an auditor: .ux/audits/ is the only place you write. .ux/cujs/ and SPEC.md are violations for this skill even though /ux-spec may write them — that asymmetry is the mechanical form of "never repair the journey you are grading". Show the real output.

Pass step 1's baseline so this measures your footprint rather than the state of the repo you walked into. The baseline forgives pre-existing dirt only while its bytes are unchanged — so if you touched a file that was already modified, this still catches you, which is the point.

It is also what keeps the positive half honest across runs. Exit 0 requires that your own writes under .ux/audits/ were observed, and in a repo that ignores that directory (SPEC §11.6) every previous run's report is still sitting there — without the baseline they would answer "were writes observed?" on your behalf forever. With it, only bytes that differ from run start count as yours.

If you never took the snapshot, say so and report the check as run without a baseline, naming the pre-existing changes it flagged. Do not quietly present the user's own uncommitted work as your violation, and do not quietly dismiss a real one as "probably theirs".

Exit criteria: all changes since the baseline confined to .ux/audits/.

Boundaries

• Never edit, refactor, or "fix" host application code. Findings only. You report the broken step; repairing it is the user's call.
• Never write to .ux/cujs/ or the host's SPEC.md. Report authoring defects; recommend /ux-spec.
• Ask first before starting a dev server, navigating a browser, performing a journey-named state reset, installing anything, or reaching auth-gated screens (the handshake for the last one is auth-handoff.md).
• Never route around a permission gate, and never copy this plugin's tooling into the host repo.
• Once a session is live, never read or store session material (cookies, localStorage, tokens), never read back a filled credential field, never leave the audited scope, never record the account identity, and never log the user out — a logout is a state reset no journey named. Full list: auth-handoff.md §7.
• Never fabricate. A step you did not observe is not a step that passed.
• No opinions. Ugly, slow, or inaccessible are real problems belonging to the other three auditors. You have no standard to judge them by.

Exit criteria (done when)

• The selected set was recorded, and an empty .ux/cujs/ stopped the run instead of passing it.
• Every selected journey validated, or was skipped and disclosed.
• Every journey's preconditions were established via a recorded rung, graded as self-referential, or skipped with a named cause.
• Every step has a verdict backed by evidence; unobserved steps are listed as not observed.
• success_criteria were scored separately, and every absence criterion has a baseline.
• Every finding names its journey and step, and its justification names both severity stages.
• One report per run under .ux/audits/, validating against the report contract, with an index row appended.
• In live/hybrid mode, each replayed step was screenshot with its stable name and the captures were assembled into a ## Walkthrough section (omitted in static mode).
• The executive summary leads with P/N journeys passed, S skipped, M of T steps verified, where N is the journeys selected.
• frameworks claims only what the run proved.
• audit_safety.py exits 0 on both halves: nothing changed outside .ux/audits/, and the writes this run made inside it were observed and listed. (git status alone is not the check — once .ux/audits/ is gitignored it shows nothing, which a run that wrote nothing satisfies identically.)
