+# Jev fault-injection results: no execution gate
+
+## September 28, 2026
+
+All **30 implemented fault injectors** were run against their configured scenarios using the no-gate controller (`f2858ef`; branch HEAD at run time `6ee75a1`). The controller and verifiers were not modified for this experiment. Clean reference: [no-gate benchmark](BENCHMARK_RESULTS_NO_GATE.md), **72/150 verified successes**.
+
+**Retained outcomes: 3 verified successes, 19 model stops, 6 repeated-state stalls, 1 step-limit exit, and 1 initialization timeout. No completion claim was rejected by the existing verifier.**
+
+The three passes preserved the outcomes actually checked: the extra background request, database delay, and missing sign-out activity-log entry. The last is a coverage gap if activity logging is part of the desired contract. The remaining non-passes must not be presented as 27 detected defects: several workflows already fail cleanly, some never reached the injected behavior, and the timeout happened before model execution.
+
+### Method
+
+- One retained attempt per fault, mapped to its existing scenario; 30 unique faults checked against `implementedFaults` and the scenario mappings.
+- Initial matrix concurrency three; fresh user and live browser session per attempt. The three infrastructure retries ran sequentially with the same controller and harness.
+- No separate execution gate or action-confidence threshold. Completion threshold 0.90; maximum 30 iterations; seven-minute loop deadline; five-entry history; existing repetition guard.
+- Existing fault installers, input values, action context, and independent Playwright assertions retained.
+- Jev API interruptions are excluded and rerun; none occurred in this matrix.
+- Three Endform/artifact interruptions were rerun once. Original attempts remain available, but the table uses their replacements. The script-delay initialization timeout was retained because it occurred under the targeted delay injection, not treated as a model-service interruption.
+- This is a one-attempt-per-fault exploratory matrix, not a repeated estimate of detection probability.
+
+Initial command:
+
+```sh
+bun scripts/jev-benchmark.ts --mode faults --concurrency 3 --output benchmark-results/no-gate-full-fault-matrix
+```
+
+The retry launcher used an unchanged copy of the benchmark controller with only the task list filtered to `unexpected-dashboard-redirect`, `session-cookie-invalid-on-dashboard`, and `invite-accepted-but-member-missing`. It ran with concurrency one and was removed afterward. The retained manifest records which original attempts were replaced.
+
+### All 30 outcomes
+
+“Clean” is the corresponding no-gate scenario’s verified count out of ten. Evidence below comes from saved decisions/snapshots and injector source inspection. It describes observed effects, not an independent assertion that every fault activated.
+

+|---|---|---:|---|---:|---:|---|

+| session-cookie-missing-mid-flow | plan-upgrade | 0/10 | Stall | 11 | 29.4s | Reached checkout but left required fields empty; cookie deletion was not independently checked. |
+| payment-server-error | plan-upgrade | 0/10 | Stall | 13 | 33.8s | Clicked purchase with missing required cardholder/billing fields; no injected server-error response observed. |
+| payment-subscription-update-skipped | plan-upgrade | 0/10 | Stall | 11 | 28.8s | Stopped at incomplete checkout; subscription-write path not demonstrated. |
+| signout-cookie-not-cleared | signout-session | 6/10 | Model stopped | 7 | 20.5s | After sign-out and dashboard navigation, Team Settings remained accessible; model stopped. |
+| signout-activity-log-missing | signout-session | 6/10 | Verified success | 4 | 17.8s | Sign-out and protected-route redirect verified; activity log is not part of this verifier. |
+| invite-accepted-but-member-missing | team-invitation | 4/10 | Step limit | 30 | 64.8s | Retry reached Team Settings with No team members yet after invite signup; repeated invitations/signup attempts until the step limit. |
+| invite-role-drift | team-invitation | 4/10 | Model stopped | 10 | 25.3s | Reached Team Settings with the invited email shown as owner rather than member; stopped at 0.14. |
+
+### What these outcomes establish
+
+**Eighteen faults now map to scenarios with at least some clean success.** Of those, three passed, thirteen ended in model stops, one stalled, and one hit the step limit. This includes duplicate invitations (6/10 clean), sign-out (6/10), and team invitation (4/10), whose fault runs previously had little interpretive value when their clean counterparts never passed. These clean rates are still imperfect, so a single non-pass is not proof of sensitivity.
+
+**Several visible effects were reached.** Missing/mislabelled activity entries, absent team members, the wrong invitation role, repeated invitation success instead of duplicate rejection, and continued authenticated dashboard access after sign-out all appear in the saved observations. These runs did not produce verified success. That is useful evidence of refusing a pass in the presence of a wrong visible outcome, but the controller usually reports a generic stop or stall rather than diagnosing the injected defect.
+
+**The password-write fault produced a particularly useful trace despite its 0/10 clean baseline.** Login with the new password failed, login with the old password succeeded, and a second cycle again failed with the new password. This is consistent with the skipped-write injection and demonstrates that the login behavior was exercised. Because the clean controller already fails the scenario, the final model stop still cannot establish a detection rate.
+
+**Twelve faults map to scenarios with zero clean successes.** These are activity ordering, email change, password change, payment history, and plan upgrade. Their non-passes do not establish fault sensitivity. Activity ordering never reached Activity in this fault run. The payment cases remained at forms missing required cardholder/billing values; placeholders were present, but filled values were absent. Clicking the purchase button under those conditions does not prove that server-side payment logic ran.
+
+**The latency and background-work cases require care.** Extra-request and database-delay injections passed because the existing verifier checks the name, not telemetry. The separate seven-second team-API delay stopped before observing the new name; that is controller intolerance of the observed timing, not proof of a permanently incorrect application result. The saved accessibility traces do not independently confirm extra-request counts or database timing.
+
+**The new sign-out pass exposes a verification boundary.** `signout-activity-log-missing` passed because the session cleared and revisiting the dashboard redirected to sign-in. Neither the aim’s implemented checks nor the verifier inspects the sign-out activity entry. It is a pass under the current contract, not evidence that the injected logging fault was detected or absent.
+
+**No verifier rejection occurred.** The three completion claims all passed their existing checks. Consequently this run does not demonstrate the verifier catching a false completion, and its current historical-transition/coverage limitations remain.
+
+### Initialization failure and infrastructure retries
+
+`script-chunk-timeout` delayed a script for 15 seconds; initial dashboard navigation timed out waiting for `load` after 15 seconds, before any model call. This is a browser/harness initialization outcome under injection.
+
+| Retried fault | Original interruption | Retained retry |
+|---|---|---|
+| unexpected-dashboard-redirect | Endform live session had already ended during the run | Model stopped after 3 steps |
+| session-cookie-invalid-on-dashboard | Endform observer WebSocket reset during startup | Model stopped after 3 steps |
+| invite-accepted-but-member-missing | Missing `25-after.png` while copying an observation artifact | Step limit after 30 steps |
+
+All three original attempts remain in the initial matrix artifacts. The retry policy addresses infrastructure-interrupted conclusions; it does not turn the retried faults into multiple independent samples or prove those interruptions were unrelated to the injected app behavior.
+
+### Cost and duration
+
+The 30 retained attempts consumed **1,645,474 input tokens** and **84,938 output tokens**, estimated at **$0.069110**. Mean duration was **28.2s**; summed duration was **844.5s**. Summed duration is not wall-clock duration. Including all three superseded infrastructure attempts, the 33 physical attempts cost an estimated **$0.073259** in total.
+
+These use the unchanged benchmark pricing assumption of $0.042 per million input tokens and free output tokens, recorded September 22, 2026. Estimates exclude Endform/browser infrastructure.
+
+### Historical comparison
+
+| Outcome | September 22 gated matrix | September 28 no-gate retained matrix |
+|---|---:|---:|
+| Verified success | 2 | 3 |
+| Model stopped | 16 | 19 |
+| Repeated-state stall | 11 | 6 |
+| Step limit | 0 | 1 |
+| Initialization failure | 1 | 1 |
+| False completion rejected by verifier | 0 | 0 |
+
+The added pass is `signout-activity-log-missing`. This comparison is historical, not a pure gate ablation: action descriptions also changed after September 22, and the default `jev-latest` alias is not a pinned model revision. The newer clean contextual-gated benchmark did not include a fault rerun.
+
+### Artifacts
+
+- Canonical retained matrix: `benchmark-results/no-gate-fault-matrix-retained/results.json` and `runs/` (includes replacement provenance).
+- Initial 30 physical attempts: `benchmark-results/no-gate-full-fault-matrix/`.
+- Three targeted infrastructure retries: `benchmark-results/no-gate-fault-infrastructure-retries/`.
+- Clean comparator: `benchmark-results/no-gate-full-clean-10x/` and [BENCHMARK_RESULTS_NO_GATE.md](BENCHMARK_RESULTS_NO_GATE.md).
+
+Each run record references its Endform directory with snapshots, decisions, and screenshots. These machine-local artifacts remain ignored by Git; this report is a new committed file. The existing clean benchmark reports remain unchanged.

+# Jev Playwright benchmark results
+
+## September 28, 2026: identifiable action descriptions
+
+Measured on branch `oliver/jev-test-loop`, implementation commit `7b6d4dc`, against the hosted Playwright tutorial application. This is the full clean benchmark: all 15 scenarios, ten runs each, with concurrency three. The September 22 results are retained as the comparison baseline below.
+
+**Result: 57/150 verified successes (38.0%), compared with 50/150 (33.3%) previously: seven more passes, or +4.7 percentage points.**
+
+### Change under test
+
+Both the single-name-change controller and the suite benchmark now retain the target accessibility reference in every element action description. A shared helper adds up to six context lines from named ancestors and preceding descriptive siblings, prioritizing the nearest heading. This uses only the existing accessibility tree, with no application-specific selectors or additional DOM reads. Selection, execution gating, and action history receive the same identifiable description.
+
+For example, the recorded pricing actions now distinguish:
+
+```text
+Click - button "Get Started" [ref=f1e59] (context: - heading "Base" [level=2] [ref=f1e18]; - paragraph [ref=f1e19]: with 7 day free trial)
+Click - button "Get Started" [ref=f1e60] (context: - heading "Plus" [level=2] [ref=f1e37]; - paragraph [ref=f1e38]: with 7 day free trial)
+```
+
+Input values and candidate combinations, the execution gate, the completion threshold, history length, and independent verification are unchanged. No named-input changes were made, keeping the experiment focused on action descriptions.
+
+### Method and validation
+
+- Fresh isolated user and Endform live-test session for each attempt; signup clears cookies and deletion starts with a fresh account.
+- Completion threshold: 0.90; execution threshold: 0.80; maximum 30 iterations; seven-minute loop deadline after startup.
+- The model sees text accessibility snapshots. Screenshots are retained for inspection, not sent to Jev.
+- Independent Playwright verification runs when Jev declares completion. Existing verifier limitations remain; these checks do not prove every historical transition required by every aim.
+- Reporting policy: attempts interrupted by Jev API failures are discarded and rerun, retaining ten completed attempts per scenario. Timing and cost describe retained attempts.
+- Eight focused unit tests passed, including duplicate button labels, scoped sibling headings, named ancestors, disabled targets, and literal action arguments. TypeScript and targeted lint checks passed.
+- Before pushing the implementation, a separate ten-run name-change validation produced **9/10 verified successes and one stall**. It is excluded from the 150-run table below.
+
+Commands:
+
+```sh
+bun test scripts/jev-loop.test.ts scripts/jev-benchmark.test.ts scripts/jev/action-context.test.ts
+bun scripts/jev-benchmark.ts --mode clean --case change-name --repeat 10 --concurrency 3 --output benchmark-results/context-name-change-10x

+| duplicate-invite | 0/10 | 0/10 | 26.9s | $0.002408 |
+| payment-history | 0/10 | 0/10 | 22.7s | $0.002885 |
+| plan-upgrade | 0/10 | 0/10 | 24.7s | $0.003683 |
+| signout-session | 0/10 | 1/10 | 25.2s | $0.001803 |
+| team-invitation | 0/10 | 0/10 | 24.1s | $0.001872 |
+| delete-account | 0/10 | 0/10 | 16.3s | $0.000587 |
+
+Outcomes: **57 verified successes, 77 repeated-state stalls, and 16 model stops**. No false completions or step/time-limit outcomes were observed under the existing checks.
+
+The retained runs consumed **5,497,283 input tokens** and **218,573 output tokens**, for an estimated **$0.230886** in Jev usage ($0.001539 per run). This uses the unchanged benchmark pricing assumption of $0.042 per million input tokens and free output tokens, recorded September 22, 2026; it excludes Endform/browser infrastructure and is not an invoice. The previous clean estimate was $0.190714.
+
+Mean duration was **21.6s**; summed duration was **3,238.6s**. Durations include startup, screenshots, model decisions, verification, and cleanup. Summed duration is not wall-clock duration because three sessions ran concurrently, and failed runs are included in the averages.
+
+### What changed, and what still fails
+
+- Signup improved from 8/10 to 10/10, activity after account update from 7/10 to 10/10, and name change from 6/10 to 10/10. Sign-out improved from 0/10 to 1/10.
+- The logged-in observation check regressed from 9/10 to 6/10. Its four stopped runs had completion scores of 0.87–0.89, below the unchanged 0.90 threshold; they never reached independent verification.
+- Eight scenarios still have zero verified successes. Identifiable targets do not resolve every execution or completion problem.
+- In payment-history run 1, the model selected the explicitly identified Plus button and reached checkout. It then repeatedly proposed the purchase button before filling the form; the execution gate rejected those proposals.
+- In activity-order run 1, the name fill and save executed, but subsequent navigation toward Security was repeatedly rejected. In password-change run 1, the password fields and submit executed, but the initials-only user-menu button was repeatedly rejected. Context from the tree cannot supply semantics that the tree does not expose.
+- Nine deletion runs stopped on the sign-in page with completion probabilities of 0.64–0.86; the other stopped on Security at 0.88. None reached verification, so apparent browser progress is not counted as a verified deletion.
+- Across all 150 attempts, the gate rejected **352/682 evaluated actions (51.6%)**. On the 130 attempts excluding signup and deletion, it rejected **345/613 (56.3%)**, compared with the previously recorded 362/618 (58.6%). These counts describe evaluated gate decisions, excluding terminal decisions before the gate.
+
+The net improvement is modest and concentrated in short workflows. This is a historical comparison with ten runs per scenario, not an interleaved randomized ablation. The model defaults to the floating `jev-latest` alias, and this benchmark does not persist the returned model revision. Date, model, and service variation can contribute to differences, so the observed gain cannot be attributed entirely to the code change.
+
+### Historical fault investigation (September 22; not rerun)
+
+The earlier 30-fault experiment remains historical evidence for the previous controller, not a measurement of this revision. Its two verified successes were `api-team-extra-request` and `api-team-db-latency-spike`, which preserved the visible name-change outcome. Eleven faults intended to disrupt visible outcomes on otherwise viable scenarios produced no verified passes. The other 17 faults targeted scenarios with no clean successes, so those failures did not establish fault sensitivity. Fault activation and reachability were not separately confirmed for every run.
+
+### Artifacts
+
+- New full clean results and generated report: `benchmark-results/context-full-clean-10x/`.
+- Separate name-change validation: `benchmark-results/context-name-change-10x/`.
+- Previous clean baseline: `benchmark-results/full-clean-10x/`, `benchmark-results/full-clean-10x-signup/`, and `benchmark-results/full-clean-10x-delete/`.
+- Historical fault matrix: `benchmark-results/full-fault-matrix-rerun/`.
+
+Each new run record points to its Endform result directory with numbered screenshots, accessibility snapshots, and step decisions. These bulky machine-local artifacts are ignored by Git; this summary is committed.

+# Clairic: driving Playwright without a list of options
+
+## October 19, 2026
+
+Jev and Clef are decision models: they can only pick from options you write down, so every earlier controller first turned the page into a menu of candidate actions. [Clairic](https://developers.cloudflare.com/workers-ai/models/clairic/), released on Workers AI as a preview on October 19, is an extraction model. It answers typed fields, and a `text` answer is an exact span of the input. That allows a much simpler loop: put the page in the state and let Clairic point at what to do next.
+
+This report benchmarks the simplest version of that loop, and two one-idea variations, against the naive Jev loop on the same 15 scenarios.
+
+### The naive Clairic loop
+
+Each step sends one plain-text state:
+
+```text
+Aim: Starting on the authenticated dashboard, change your name to John Doe in general settings. ...
+Success criteria:
+- The account update success message has been observed after saving.
+- ...
+Supplied values: "John Doe"
+Direct URLs: /dashboard
+Actions so far:
+1. Clicked - button "General" [ref=e20] -> done; now on /dashboard/general
+Current page: https://.../dashboard/general (Playwright Tutorial)
+Page accessibility tree:
+- generic [ref=e1]:
+  ...
+```
+
+and asks four `text` fields:
+
+| Field     | Asks for                                                                 |
+| --------- | ------------------------------------------------------------------------ |
+| `element` | The ref (like e12) of the interactive element to click or type into next |
+| `text`    | The supplied value to type into it, or null                              |
+| `url`     | A path from Direct URLs to open instead, or null                         |
+| `done`    | A quote of the text showing every success criterion is met, or null      |
+
+The code is a few rules. If `done` is not null, independent Playwright verification decides the outcome. Otherwise, if `element` names a ref on the page, its role decides the action: textboxes are filled with `text`, checkboxes and radios are checked, and everything else is clicked. If not, `url` is opened. With neither, the run stops. That is the whole controller: no candidate actions, no thresholds, and no app-specific rules. Settling after actions, the 30-step and seven-minute limits, the repeated-state guard, and the strengthened verifiers are shared with the Jev runs.
+
+The two variations each change one thing:
+
+- `clairic-screenshot` also sends the page screenshot.
+- `clairic-clef` drops the `done` quote and asks Clef, in parallel, "Have ALL success criteria been met?" (claimed at ≥ 0.90), like the Jev loop's completion question.
+
+The reference `text` is the September no-gate Jev loop on Jev 1.14: a menu of click, fill, and check options built from the same accessibility tree.
+

+
+The Jev reference reproduces the October 16 measurement of the same controller (110 vs 109 of 150).
+
+### What worked
+
+**Pointing works for the next step.** Without any option list, Clairic usually named a real, sensible element: in change-name it went General → typed "John Doe" into Name → Save Changes, the same opening as a hand-written test. Invalid references were rare (9 of 1,201 steps in `clairic`), as were clicks on non-interactive containers (25) and typed text that was not a supplied value (9).
+
+**Short tasks pass every time.** Every Clairic variant passed the three observation checks (activity-section, has-title, already-logged-in) 10/10. `clairic` and `clairic-clef` passed delete-account 10/10, where the Jev loop never did: Jev's completion score stayed just under 0.90 and it chose to stop.
+
+### What failed
+
+**The model quotes the goal as proof.** Asked to quote the text showing the aim is complete, `clairic` produced a quote 100 times. 73 of those came from the aim, success criteria, or action log, not the page: it quoted "Delete the current account by entering…" or "The current page is Sign in" from the state itself. In change-name it quoted "Account Information" right after saving, one step before returning to Team Settings. That produced 58 false completions, all rejected by verification. Passes happened only when the work was already finished by the time a quote appeared.
+
+**Without that shortcut, it does not know when to stop.** With Clef judging completion, false completions dropped to zero, but 97 of 150 runs stalled or hit the step limit. The action log says what was clicked, not what the page answered, so after "Save Changes" Clairic saw no reason to move on and clicked Save again until the repeat guard ended the run. Clef's completion score stayed low: across the 97 failed runs, the median of each run's highest score was 0.02 (90th percentile 0.04).
+
+**Multi-step flows mostly never finish.** In `clairic`, apart from delete-account, every scenario that needs more than a couple of actions scored at most 2/10; `clairic-clef` also passed activity-after-account-update 10/10, and nothing longer. Typical traces bounce between pages (plan-upgrade: Change Plan → open /dashboard → Change Plan again): 25–35% of all steps opened a direct URL, and 95% of those in `clairic` reopened `/dashboard`. Checkout was reached in about half of the plan-upgrade and payment-history attempts and never completed.
+
+**The screenshot made it worse again.** As with Jev, adding the screenshot lowered the pass rate (28% → 20%), raised cost 2.4×, and added more stops and stalls.
+
+### Cost and speed
+
+Clairic is priced at $0.10 per million input tokens (Jev: $0.042; Clef: $0.24), with no output charge. A naive Clairic attempt cost about $0.0035 against $0.0019 for Jev, mostly from the higher price; `clairic-clef` pays for two models per step. In a manual check, Clairic answered a 2,800-token state in about 0.6 seconds; per-request latency was not recorded in the benchmark.
+
+### Method and limits
+
+- All four variants ran interleaved, scenario by scenario, with fresh users and live Endform sessions. The batch started at concurrency 6 and was resumed at concurrency 9 to finish sooner; the six attempts in flight at the switch were rerun.
+- Three attempts failed on infrastructure (a screenshot that never transferred back from the Endform worker, and a live session that ended early). They were moved aside and rerun; none of the replacements passed.
+- The loop was fixed after two smoke runs on three scenarios, before this batch: the first version mixed "element or URL" in one field (Clairic pointed at the URL line instead of the page) and read whole spans, which can run on into the next line of the state. The measured version splits `url` into its own field and reads the first token of each span.
+- Clairic is a preview checkpoint, released the day of this benchmark. Each scenario has ten attempts.
+
+### Takeaways for a naive implementation
+
+Letting the model point instead of choose makes the controller very small: four fields and a role lookup, no menu building. On this suite that simplicity costs reliability. The naive Clairic loop passes 28% of attempts against 73% for an equally naive option menu with Jev. The gap comes from completion and memory, not from finding elements. The obvious next steps are the same lessons the Jev stepwise controller learned: record what the page said after each action, only accept completion evidence that comes from the page, and track progress through the parts of the aim.

+# Jev with screenshots, and a stepwise controller
+
+## October 16–18, 2026
+
+Jev 1.14 (released October 14) accepts images and adds a `box` question type. This report measures what giving Jev the page screenshot does to the 15-scenario suite, then what a more general controller achieves with and without it.
+
+| Variant         | Controller           | Model        | Screenshot |            Verified |
+| --------------- | -------------------- | ------------ | ---------- | ------------------: |
+| `text-1.13`     | September 28 no-gate | `jev-1.13.0` | no         |  **77/150 (51.3%)** |
+| `text`          | September 28 no-gate | `jev-1.14.0` | no         | **109/150 (72.7%)** |
+| `images`        | September 28 no-gate | `jev-1.14.0` | yes        |  **79/150 (52.7%)** |
+| `stepwise-text` | stepwise             | `jev-1.14.0` | no         | **149/150 (99.3%)** |
+| `stepwise`      | stepwise             | `jev-1.14.0` | yes        |  **150/150 (100%)** |
+
+**Adding the screenshot to the existing controller cost 30 verified passes (72.7% → 52.7%).** The model upgrade alone gained 32 (51.3% → 72.7%). With the stepwise controller, the screenshot made no measurable difference (150 vs 149) at 2.4× the Jev cost.

+
+A full-page screenshot (1280 px wide) adds about 2,600 input tokens per request. Cost uses $0.042 per million input tokens with free output, unchanged from September; durations include Endform session startup, verification, and cleanup.
+
+### Why the screenshot hurt the existing controller
+
+The screenshot was the only change in `images`: same candidates, history, thresholds, and questions, with "`screenshot` and accessibility tree" named as the current page.
+
+- **Completion scores moved under the 0.90 threshold.** has-title and signout-session reached the right page in every attempt, but Jev's final completion probability was 0.71–0.84 with the screenshot, against 0.86–0.94 text-only. Jev then chose _stop_ because nothing was left to do, ending the run unverified. The old stop option meant both "finished" and "impossible".
+- **Checkout was submitted early.** With the screenshot, Jev filled one or two fields and then clicked "Complete Purchase" repeatedly; browser validation blocked each submit without visible change. Text-only filled the fields in order and, after a blocked submit, followed the `[active]` marker the browser put on the first invalid field.
+- **It did help where the action is visual.** duplicate-invite rose from 6/10 to 10/10 and team-invitation from 9/10 to 10/10.
+
+### The stepwise controller
+
+Every change is a flag in `variants.ts` (described in [the README](README.md#variants-screenshots-and-the-stepwise-controller)). None uses application-specific selectors or text; each targets a failure seen in traces:
+
+| Failure in traces                                                                                        | Change                                                                                                                                                                      |

+
+Stepwise asks two requests per iteration (progress, then action), so it uses more requests but fewer tokens per request without screenshots: $0.0015 per attempt text-only versus $0.0036 with screenshots.
+
+The single stepwise failure (`stepwise-text` team-invitation #4) completed the invitation and signup, reached Team Settings with both members, then stayed uncertain on the final confirmation (completion 0.50–0.67) and waited on an unchanged page until the repeat guard stopped it.
+
+Jev's `box` question type was not used: every candidate action is already grounded by its accessibility reference, so locating it in pixels adds nothing on this application.
+
+### Verification
+
+Making completion claims easier exposed weak verifiers. During development, the controller chose _finish_ on the first step of change-password and passed, because that verifier only checked that the dashboard was showing, which is true at the start. Three verifiers now check the outcome instead (`cases.ts`):
+
+- change-password: the activity log shows a sign-in after the password change, and the new password signs in from a fresh browser context.
+- change-email: the email is persisted, and the activity log shows a sign-in after the account update.
+- delete-account: the deleted credentials no longer sign in.
+
+Each was checked against both directions in a live session: it rejects the untouched start state and accepts a scripted genuine completion. The stepwise batch used these verifiers; the first batch used the original ones. Its only passes on these three scenarios were six `text-1.13` delete-account attempts, and their traces show a genuine deletion.
+
+### Fault injection
+
+All 30 faults ran once per stepwise variant (`--mode faults`).
+
+| Outcome                              | stepwise | stepwise-text |
+| ------------------------------------ | -------: | ------------: |
+| Verified success                     |        6 |             7 |
+| False completion (verifier rejected) |        3 |             3 |
+| Model stopped                        |       15 |            15 |
+| Repeated-state stall                 |        3 |             3 |
+| Step limit                           |        2 |             1 |
+| Error before the first decision      |        1 |             1 |
+
+No pass broke a verified outcome:
+
+- `api-team-extra-request`, `api-team-db-latency-spike`, and (`stepwise-text` only) `api-team-latency-spike` only add requests or delay; the September controller also passed the first two.
+- `script-404` and `script-chunk-404` fail only the first script request; the flow works after the next navigation, and Jev completed it.
+- `api-user-malformed-json` breaks the client `/api/user` fetch, but the root layout seeds SWR with server-fetched user data, so General still shows the persisted email.
+- `signout-activity-log-missing` drops an activity entry that no verifier checks (also passed in September).
+
+The three payment faults now reach checkout and pay; Jev claimed completion and the payment verifier rejected each claim. In September these faults were never reached. `script-chunk-timeout` fails the initial navigation before Jev runs.
+
+### Method and limits
+
+- Variants ran interleaved, scenario by scenario, at concurrency 6, so each comparison shares app, Jev service, and infrastructure conditions. The second batch started while the first was running.
+- Both batches were interrupted when the controlling session ended on October 16 and were resumed on October 18 with `--resume` (82 of 450 and 192 of 300 attempts ran then, at concurrency 5). Twenty attempts whose live session failed to start (TLS and registration errors) were rerun; those are infrastructure, not outcomes. No Jev API retries were needed.
+- The stepwise controller was developed with smoke runs on these 15 scenarios. It avoids application-specific rules, and the fault matrix checks it still fails when outcomes break, but its 100% is on the suite it was tuned against. 150/150 bounds the per-attempt failure rate only to roughly 2% (95%, rule of three).
+- The aim splitter assumes aims written as sentences and comma-separated clauses, as all 15 are.
+- Jev's completion probability remains poorly calibrated early: 0.72–0.81 at the start of change-password. The progress gate, not the threshold, kept those from becoming claims.
+
+### Conclusion
+
+On this suite, screenshots are not where the gains are: dropped into the existing loop they made things worse, and in the stepwise loop they are within noise of text-only for 2.4× the cost. The controller changes moved the suite from 72.7% (same model) to 99–100%, so this suite is saturated; further work needs harder scenarios rather than more tuning here.

+# Jev benchmark: no execution gate
+
+## September 28, 2026 comparison
+
+**72/150 verified successes (48.0%) without the gate, compared with 57/150 (38.0%) with it: +15 verified passes, or +10.0 percentage points.**
+
+This report is separate from [the contextual gated benchmark](BENCHMARK_RESULTS.md), which remains unchanged. Both runs use contextual action descriptions, all 15 clean scenarios, ten repetitions each, and concurrency three. The no-gate implementation is commit `f2858ef`; the gated implementation is `7b6d4dc` (results committed in `c9c124e`).
+
+### The single algorithm change
+
+The selector still judges completion and chooses among bounded click/fill/check/navigation actions plus wait and stop. The chosen action now executes directly, without a second Jev request or action-confidence threshold. Existing candidate filtering, reference validation, supplied-value restrictions, and Playwright action checks remain.
+
+The completion threshold remains 0.90. The suite still allows 30 iterations and seven minutes after startup, retains five history entries, and stops after the fourth repeated selection on the same snapshot. Input values, contextual descriptions, action-selection instructions, completion instructions, setup/cleanup, and independent verification are unchanged. No extra delay, progress tracking, or verifier changes were introduced. Removing a model call also changes the elapsed time between observing the page and acting on it.
+
+### Validation and reporting policy
+
+- Eight focused unit tests, TypeScript, targeted lint, and whitespace checks passed.
+- The requested single name-change smoke run **stopped without verification** after six steps. It executed the name fill and save, then navigated to Team Settings while the prior snapshot still showed `Saving...`. John Doe was visible on Team Settings, but the required success message had not been observed; completion remained at 0.44–0.46. This smoke result is retained separately and excluded from the 150-run table.
+- The implementation was frozen after that smoke run. The full benchmark was run without tuning it to the smoke outcome.
+- Attempts interrupted by Jev API failures are discarded and rerun so each scenario retains ten completed attempts. No such replacements were needed in this batch.
+- All 150 retained attempts have one model request per iteration; inspection of the saved decision records confirmed no execution-gate calls.
+- These are the 15 clean scenarios. Fault injection was not rerun in this comparison.

+### Aggregate comparison
+
+| Metric | Gated | No gate |
+|---|---:|---:|
+| Verified success | 57 (38.0%) | 72 (48.0%) |
+| Repeated-state stall | 77 | 10 |
+| Model stopped | 16 | 67 |
+| Step limit | 0 | 1 |
+| False completion under existing verification | 0 | 0 |
+| Mean iterations per attempt | 5.55 | 7.79 |
+| Model requests | 1,514 | 1,169 |
+| Input tokens | 5,497,283 | 5,669,571 |
+| Output tokens | 218,573 | 300,474 |
+| Estimated total Jev cost | $0.230886 | $0.238122 |
+| Mean attempt duration | 21.6s | 23.0s |
+| Summed attempt duration | 3,238.6s | 3,445.6s |
+| Successfully executed browser actions (excludes waits) | 311 | 879 |
+| Executed waits | 19 | 140 |
+| Browser action execution errors | 0 | 1 |
+
+Model requests fell by 22.8%, but total estimated Jev cost rose by 3.1% and mean duration rose by 6.4%. Longer trajectories and larger later-history contexts offset the removed gate requests. Cost uses the unchanged assumption of $0.042 per million input tokens and free output tokens, recorded September 22, 2026. It excludes Endform/browser infrastructure and the separate smoke test. Durations include setup, screenshots, model calls, verification, and cleanup; summed duration is not wall-clock duration because three sessions run concurrently.
+
+### What improved
+
+- Duplicate invitation improved **0/10 → 6/10**.
+- Sign-out improved **1/10 → 6/10**.
+- Team invitation improved **0/10 → 4/10**.
+- Every other scenario retained the same verified-pass count as the gated comparison. Six scenarios still have zero verified successes.
+- Name change remained **10/10** in the full batch and became faster and cheaper on average, despite the separate smoke run exposing a timing-sensitive failure.
+
+### Remaining failures and observed downsides
+
+**More progress does not guarantee recognized completion.** Activity-order run 1 executed the name update, password update, and navigation to Activity, but subsequently returned to General and stopped without verification. Email-change run 1 updated the email, signed out, filled the new email and password, submitted sign-in, then stopped later at 0.67 completion confidence. Past milestones can fall outside the unchanged five-entry history.
+
+**Repeated mutations replace some gate stalls.** Password-change run 1 changed the password and signed in using the new password, then revisited Security and tried to change it again with the old current password. Later snapshots showed `Current password is incorrect.` and `New password must be different from the current password.` All ten password scenarios still failed; one reached the 30-step limit, and mean duration grew from 30.6s to 54.9s.
+
+**Premature checkout actions remain a problem.** Payment history had ten model stops and plan upgrade had ten repeated-state stalls. These workflows did not gain a verified pass from executing actions that the gate had previously rejected.
+
+**Removing the gate also removes incidental waiting.** The smoke run navigated away while saving was still in progress, before capturing the success message. This is evidence for investigating explicit observation of pending work in a future variant, not a reason to silently add a delay to this one.
+
+**Execution success is narrower than task success.** The single recorded browser execution error was a five-second fill timeout in email-change run 3. Validation errors and unnecessary submissions usually do not throw Playwright errors, so the 879 successful browser-action calls are not 879 correct decisions.
+
+### Interpretation and limits
+
+This batch supports removing the generic execution gate as a useful direction: it increased verified completion by ten percentage points and unlocked three previously difficult workflows. It did not improve every task or lower aggregate cost and runtime. Completion recognition, short history, and form behavior remain important limitations.
+
+The same independent verifiers were deliberately retained for comparability. They do not establish every required historical transition (for example, the password verifier only checks the final dashboard), so zero observed false completions does not prove the no-gate controller cannot falsely pass. Stronger verification and a fresh fault-injection experiment would be needed for that claim.
+
+The runs were sequential batches on the same date, not an interleaved randomized experiment. Each scenario has ten repetitions. The controller defaults to the floating `jev-latest` alias and does not persist the returned model revision, so service/model variation can affect comparisons.
+
+### Artifacts
+
+- No-gate full batch: `benchmark-results/no-gate-full-clean-10x/results.json` and `report.md`.
+- Separate no-gate smoke: `benchmark-results/no-gate-name-change-smoke/`.
+- Gated comparison batch: `benchmark-results/context-full-clean-10x/`.
+- Gated summary: [BENCHMARK_RESULTS.md](BENCHMARK_RESULTS.md).
+
+Run records point to local Endform directories containing all step decisions, accessibility snapshots, and screenshots. These bulky machine-local artifacts remain ignored by Git; this comparison is committed separately.

+# Blog outline: Using Jev to dynamically run Playwright tests
+
+Draft brief for the writing team. Branch: `oliver/jev-test-loop`. Use **Jev**, **Playwright**, and **Endform** consistently throughout.
+
+## Title options
+
+- **Using Jev to Dynamically Run Playwright Tests** — recommended; clear and direct.
+- **Can Jev Choose the Next Step in a Playwright Test?**
+- **Jev Meets Playwright: Cheap Decisions, Tricky Tests**
+- **We Let Jev Drive Playwright: What Worked and What Stalled**
+- **150 Attempts with Jev and Playwright: The Promise and the Limits**
+
+## Editorial direction
+
+- An honest engineering experiment: can a classifier choose browser actions from a goal and the current page?
+- Lead with the contrast in the results: excellent performance on narrow observation checks, some success with simple changes, substantial difficulty elsewhere, and very low model costs.
+- This is a deliberately naive implementation, not a verdict on Jev's capabilities or a production-ready testing framework.
+- Compare outcomes across converted scenarios. We did not run a controlled speed or cost comparison against ordinary Playwright or a generative browser agent.
+
+## 1. Introduction: let Jev choose what Playwright does next
+
+- We used Jev to select and execute steps dynamically inside Playwright tests, then measured success, duration, and model cost.
+- Starting point: an existing tutorial suite with known workflows, fixtures, and expected outcomes.
+- Hook: 150 attempts cost approximately **$0.19 in Jev usage**, but only **50 passed verification**. The interesting story is which tests worked and why the others struggled.
+- Preview the question: could instructions such as “fill out this form with these details” replace some hand-written interaction code while retaining the test harness?
+
+## 2. Why a classifier inside a test runner?
+
+- Introduce Jev as a classifier: in this experiment it chooses among supplied actions and scores yes/no questions. It does not generate arbitrary Playwright code.
+- Distinguish one-time AI conversion of existing tests into frozen text specifications from the runtime loop. No generative model writes steps during execution.
+- Keep Playwright fixtures and the harness: create an isolated user, establish a logged-in session, control the browser, verify outcomes, and clean up.
+- Hypothesis: some interactions could be described by intent and supplied data, with Jev selecting the concrete action at runtime.
+- The experiment tests that division of responsibility; it does not eliminate authored test expectations or setup code.
+
+## 3. The approach: a Bun script, Endform live test, and a decision loop
+
+- Introduce Endform live-test functionality: start a Playwright session and issue commands into the running browser while retaining its state and fixtures.
+- Each scenario supplies a frozen aim, input values, and success criteria. The controller is a Bun script calling the Endform CLI and Jev API.
+- Decision-loop diagram ([editable Excalidraw source](./diagrams/jev-playwright-loop.excalidraw), [SVG](./diagrams/jev-playwright-loop.svg)):
+
+  ![Jev selects from candidate actions built from the aim and current accessibility snapshot. A separate execution gate allows a Playwright action, then a fresh snapshot feeds the next iteration. Completion claims go to independent Playwright checks.](./diagrams/jev-playwright-loop.svg)
+
+- Endform automatically saves an AI accessibility snapshot after commands. The controller reads it and maps element references to concrete Playwright locators.
+- Build click, fill, and check choices, plus navigation, wait, and stop options. In the naive version, every supplied input value can be paired with every textbox.
+- Send the aim, criteria, URL/title, snapshot, candidates, and the last five action observations to Jev. Ask which action to take and whether the task is complete; use a separate request to judge whether the chosen action should execute.
+- Completion threshold: 0.90. Execution threshold: 0.80. These are experimental settings, not calibrated reliability guarantees.
+- End on a verified completion, an explicit stop, repeated unchanged state/action, a limit, or an error. Benchmark limits: 30 iterations and seven minutes after startup.
+- Independent Playwright assertions check completion claims; they do not guide action selection. They are adapted checks, not proof of equivalence with every original assertion.
+- Screenshots are explicitly captured by our controller and transferred back by Endform. They are inspection artifacts; Jev receives text, not images. Preserve this distinction from the automatic snapshots.
+
+## 4. Converting the tutorial suite and measuring it
+
+- Convert all 15 listed tests into frozen scenarios, adapting signup/setup and deletion/teardown to isolated accounts. Run each ten times: **150 attempts**, with three concurrent sessions.
+- Track verified success, explicit stop, repeated-state stall, and infrastructure/API errors, alongside duration and reported token usage.
+- Use the full per-test table from [BENCHMARK_RESULTS.md](./BENCHMARK_RESULTS.md); a grouped chart can introduce it:
+
+| Scenario group | Verified successes | What it suggests |
+|---|---:|---|
+| Observation checks: title, activity section, logged-in state | 29/30 | Strong performance when the required evidence is already visible |
+| Signup, name change, activity after an update | 21/30 | Promising but inconsistent on short interaction flows |
+| Remaining nine scenarios | 0/90 | This implementation struggled with longer flows, ambiguity, and completion decisions |
+
+- Overall: **50/150 (33.3%)** verified success; **73 stalls**, **25 explicit stops**, **2 HTTP 529 errors**.
+- Mean duration: **21.7 seconds per attempt**, including session startup, screenshots, verification, and cleanup. Fast failed attempts are not evidence of fast successful execution.
+- Estimated Jev cost: **$0.190714 total**, **$0.001271 per attempt** (about 0.127 US cents). Includes failed attempts; excludes browser/Endform infrastructure, development, and one-time specification generation. Two failed API responses had no reported usage.
+- Ten attempts per scenario provide exploratory evidence, not a precise reliability estimate. Pricing is the rate recorded for this experiment; link the pricing source in the results/README and verify it before publication.
+
+## 5. What worked, what sometimes worked, and what never passed
+
+### Consistently strong: evidence already on the page
+
+- Title and activity-section checks: **10/10** each. Logged-in state: **9/10**.
+- Little navigation, few ambiguous choices, and success evidence available directly in the observation.
+- This supports a narrow claim about this suite's observation tasks; these are also relatively easy tasks.
+
+### Partial success: short visible changes
+
+- Signup: **8/10**; activity after account update: **7/10**; name change: **6/10**.
+- Traces show inconsistent completion judgments and action/gate disagreement. A viable next action can be selected and then rejected, leaving the browser unchanged.
+- Explain one successful and one stalled name-change run to make the loop concrete. Choose actual artifacts rather than inventing dialogue or model reasoning.
+
+### Zero verified successes: several different kinds of failure
+
+- List the nine cases: activity ordering, email change, password change, duplicate invitation, payment history, plan upgrade, sign-out, team invitation, and account deletion.
+- Group observed contributing factors rather than attributing every failure to a single cause:
+  - Ambiguous descriptions: identical “Get Started” choices without useful ancestor context; user-menu buttons identified by initials.
+  - Too many poorly distinguished actions: checkout produced 88 candidates from pairing values with fields; premature submission also occurred.
+  - Longer workflows: navigation, account transitions, and limited history make progress and completion harder to establish.
+  - Completion false negatives: deletion appeared to complete, but scores below 0.90 prevented verified success. Zero benchmark passes does not always mean zero useful browser actions.
+- Present these as observations and plausible contributors. We did not run ablations proving how much each change would improve results.
+
+## 6. Injecting failures: did the tests stop and fail?
+
+- Inject faults into scenarios that otherwise passed to see whether the loop stops when the expected outcome is broken.
+- Sometimes Jev stopped correctly; sometimes it stalled on an unchanged state until the controller ended the run.
+- The correct stops are encouraging. The stalls are a weakness: the test ends without success, but does not clearly recognize or explain what went wrong.
+- Takeaway: the loop showed some useful failure handling, but getting stuck is not the same as detecting a failure cleanly.
+
+## 7. What the naive approach teaches us
+
+- There are two lossy transformations: **web page → accessibility representation → finite action menu**.
+- The first can omit visual relationships and application state; the second can discard context, collapse meaningful distinctions, and introduce implausible choices.
+- Jev must classify the representation we supply. Missing information or poorly constructed candidates cannot be repaired merely by choosing a label.
+- Our gate design, short history, and fixed thresholds add further limitations. Avoid implying all failures are inherent to classifiers.
+- Possible follow-up experiments: preserve ancestor context, associate values with fields, represent progress explicitly, and simplify or calibrate the execution gate. Clearly label these as untested ideas.
+
+## 8. Conclusion: cheap enough to explore, selective enough to be useful
+
+- Return to the evidence: very strong on narrow checks, mixed on simple mutations, unsuccessful on the remaining scenarios in this implementation.
+- The measured model cost makes repeated dynamic decisions inexpensive enough to investigate in bounded parts of a conventional Playwright suite. We have not established comparative savings against another agent.
+- Third-party forms, such as Stripe checkout, are a possible future use case: retain deterministic setup/assertions and delegate a bounded interaction. **Our checkout scenarios failed, and we did not demonstrate successful Stripe automation**; present this as a hypothesis that needs better representations and validation.
+- Close with an invitation: “Where would a small, dynamic step help in your Playwright tests? We'd be curious to hear which parts of testing your own web applications would suit this approach.”
+
+## Handoff references

+- [Benchmark controller](../jev-benchmark.ts), [frozen scenarios and verification](./cases.ts), and [Playwright harness](./suite-harness.spec.ts).
+- Raw benchmark folders and screenshots are Git-ignored and contain local paths. Sharing the branch alone will not give the writing team those artifacts; export selected runs separately if illustrations are needed.

+# Jev test loop
+
+Run from the repository root:
+
+```sh
+bun run jev:test
+```
+
+Requires installed project dependencies, an authenticated Endform CLI (`pnpm exec endform login`), and `JEV_API_KEY=...` in the git-ignored `.env.jev` file. The controller loads that file automatically and removes the key from the Endform subprocess environment. `JEV_MODEL` optionally selects a model (default `jev-latest`); `ENDFORM_BIN` optionally points to another CLI binary. `BASE_URL` overrides the hosted tutorial app.
+
+`name-change.json` is the frozen, AI-authored text specification derived from `tests/change-name.spec.ts`. It contains the aim, supplied text values, and success criteria, not locators or an action sequence. The minimal harness uses the same user creation/cookie/cleanup helpers as that test. Its separate Playwright config avoids the original suite's telemetry dependency and setup projects.
+
+The Bun controller starts one Endform live session, paused before the harness body, and navigates to the authenticated dashboard. Every iteration reads the current AI accessibility snapshot and creates click/fill candidates using its references. Jev chooses the next action and judges completion in one request. Selected actions execute without a separate model execution gate or action-confidence threshold. Only supplied input values can be entered. No generative model runs inside the loop.
+
+Current experimental completion threshold: >= 0.9. The loop allows 20 iterations, five minutes after startup, and at most three repetitions of an action on an unchanged snapshot. These are initial settings, not calibrated confidence guarantees. Execution failures return to observation; terminal failure exits nonzero.
+
+When Jev says done, independent Playwright checks require an observed success message, the team page, and the updated name both before and after reload. These checks never guide Jev. Session cleanup runs on completion, failure, or Ctrl-C (after the in-flight command finishes). The terminal prints every available action with its Jev probability, the selected action, and the completion probability.

+`scripts/jev/cases.ts` contains the frozen aims, supplied values, success criteria, independent verification code, and fault mapping. Setup and teardown are adapted to run independently: signup begins with cleared cookies and cleans up its created account, while account deletion receives a fresh authenticated user. The default concurrency is three and can be overridden with `--concurrency N`. Reports are written under the ignored `benchmark-results/` directory. Its `screenshots/` folder links to every run's numbered images. Individual run records link to the corresponding Endform result directory with per-step choices and automatic accessibility snapshots.
+
+Outcomes distinguish verified success from false completion, an explicit model stop, repeated-state stalls, limits, and infrastructure or script errors. Timings include Endform session startup, the Jev loop, independent verification, and cleanup.
+
+Both controllers retain each target's live accessibility reference in its action description. They also include up to six context lines from named ancestors and preceding descriptive siblings within those ancestors (prioritizing the nearest heading). This distinguishes repeated labels such as pricing-card buttons using the existing accessibility tree, without application-specific rules or extra browser reads. The same description reaches action selection and history. The no-gate variant preserves input candidates, the completion threshold, and verification.
+
+## Variants, screenshots, and the stepwise controller
+
+`--variants a,b,...` runs several controller configurations in one batch. Each scenario runs once per variant before the next scenario starts, so variants share the app, Jev service, and infrastructure conditions instead of running in separate batches. `scripts/jev/variants.ts` defines them; each flag is one general algorithm change, and none uses application-specific selectors or text:
+
+| Flag          | Change                                                                                                                                                                                                                                                                                                                                                                                                             |
+| ------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
+| `images`      | Send the current full-page screenshot as a Jev image asset (`TypeSafe-Danger-Zone-Images: true`), next to the accessibility tree. Tall pages are scaled to fit Jev's 280–1568 px limits (`images.ts`).                                                                                                                                                                                                             |
+| `settle`      | After each action, wait until no request younger than five seconds is in flight and the accessibility tree has been unchanged for 500 ms (at most five seconds), then observe.                                                                                                                                                                                                                                     |
+| `memory`      | Keep every past action in history, each with its result, resulting page, and the page text that appeared (`newPageText`), instead of the last five actions with full accessibility trees. Unchanged pages are reported as such.                                                                                                                                                                                    |
+| `fieldValues` | Offer one fill per field instead of every value × every field; a Choice per field picks which supplied value (or none) belongs there. Fills that would leave a field unchanged are skipped. Actions report the browser's constraint-validation bubble (for example "Please fill out this field."), which neither screenshots nor accessibility snapshots capture.                                                  |
+| `finish`      | Split the old stop option into _finish_ (a completion claim, independently verified like done ≥ 0.9) and _stop_ (the aim cannot be reached).                                                                                                                                                                                                                                                                       |
+| `skipNoops`   | Do not offer an action again on a page state it left unchanged.                                                                                                                                                                                                                                                                                                                                                    |
+| `steps`       | Split the aim into its ordered clauses (`progress.ts`). Each iteration first asks one Noul per unfinished part, extends the run of finished parts from the start (finished parts stay finished), then asks for the action that accomplishes the current part. Completion claims need every part but the last to be finished. Within a part, an action already tried from the same page state is not offered again. |
+| `escape`      | Offer pressing Escape. Modal menus hide the rest of the page from the accessibility tree, leaving no other way back.                                                                                                                                                                                                                                                                                               |
+
+`text-1.13` reproduces the September 28 no-gate controller; `text` is the same controller on Jev 1.14; `images` adds only the screenshot. `stepwise` enables every flag and is the default (`bun run jev:benchmark`); `stepwise-text` is the same without screenshots, measured within noise of it at under half the Jev cost. Variants pin `jev-1.14.0` (or `jev-1.13.0`) rather than a moving alias. Jev's `box` question type is not used: every candidate is already grounded by its accessibility reference. The single-scenario `bun run jev:test` demo above is unchanged and remains text-only.
+
+A run whose live session fails to start is retried up to twice; failures after the session starts are always counted. `--resume` with the same `--output` keeps recorded attempts (except sessions that never started) and runs the rest. Jev 429/5xx responses are retried with backoff and counted per run (`apiRetries`).
+
+```sh
+bun scripts/jev-benchmark.ts --mode clean --repeat 10 --concurrency 6 --variants text,images,stepwise,stepwise-text
+```
+
+The change-password, change-email, and delete-account verifiers originally passed on states a premature completion claim could reach (the dashboard is already showing at the start of change-password). They now check the outcome: the activity log must show a sign-in after the password change or account update, the new password must sign in from a fresh browser context, and deleted credentials must no longer sign in.
+
+## Clairic: pointing instead of choosing
+
+[Clairic](https://developers.cloudflare.com/workers-ai/models/clairic/) is Cloudflare's extraction model (Workers AI, preview since October 19, 2026). Instead of choosing among options, it answers typed fields; a `text` field is an exact span of the input. The `clairic` controller (`clairic.ts`) uses that to drop candidate actions entirely. Each step sends one plain-text state:
+
+```text
+Aim, success criteria, supplied values, direct URLs (/dashboard and any captured invitation URL),
+a numbered log of past actions ("Clicked - button "General" [ref=e20] -> done; now on /dashboard/general"),
+the current URL and title, and the accessibility tree
+```
+
+and asks for four span fields:
+
+| Field     | Instruction (abridged)                                                   |
+| --------- | ------------------------------------------------------------------------ |
+| `element` | The ref (like e12) of the interactive element to click or type into next |
+| `text`    | The supplied value to type into that element, or null                    |
+| `url`     | A path from Direct URLs to open instead, or null                         |
+| `done`    | Quote the text showing every success criterion is met, or null           |
+
+Code turns the answers into one action: if `done` is not null, independent verification runs. Otherwise, if `element` is a reference on the page, its role decides the action (textboxes are filled with `text`, checkboxes and radios are checked, everything else is clicked); otherwise `url` is opened; with neither, the run ends as a model stop. Only the first token of a span is read, because spans can run on into the next line. Actions settle like the stepwise controller; the 30-step, seven-minute, and repeated-state limits are unchanged.
+
+`clairic-screenshot` adds the page screenshot (`images`), and `clairic-clef` replaces the `done` quote with a Clef Noul ("Have ALL success criteria been met?", claimed at ≥ 0.90), asked in parallel.
+
+Clairic variants need `CLOUDFLARE_ACCOUNT_ID` and a Workers AI `CLOUDFLARE_API_TOKEN` in `.env.jev`; the token is removed from the Endform subprocess environment like `JEV_API_KEY`. Cost uses Workers AI input prices ($0.10 per million tokens for Clairic, $0.24 for Clef; no output charge), recorded in the existing `estimatedJevUsd` field.
+
+```sh
+bun scripts/jev-benchmark.ts --mode clean --repeat 10 --concurrency 6 --variants text,clairic,clairic-screenshot,clairic-clef
+```
+
+## Inspect a run
+
+To watch screenshots arrive in a browser, start the local viewer:
+
+```sh
+bun run jev:viewer
+```
+
+Open http://127.0.0.1:3031, then run `bun run jev:test` in another terminal.
+Keep the viewer beside your editor or terminal. It polls every 500 ms and displays
+the newest complete screenshot without refreshing the page. These are still images
+captured after each step, not browser video; the last image remains after the run ends.
+
+The controller writes its session and results directory to
+`test-results/jev-current-run.json` when the session starts. The viewer follows this
+pointer automatically, including when you start another run. Both the pointer and
+screenshots are published with atomic renames so the viewer never reads a partially
+written file. The pointer is ignored by Git with the rest of `test-results/`.
+This viewer follows the single `jev:test` controller, not concurrent benchmark runs.
+
+The script prints its Endform results folder (`test-results/live-session-<session-id>/`). It contains:
+
+- `screenshots/00-initial.png`, numbered `NN-after.png` images after each action, wait, or rejection, and a final `NN-verified-after-reload.png` on success. The initial image is the state for decision 1; each after-image is the state for the next decision.
+- `step-NN-choices.json`: all candidates, answer probabilities, action result.
+- `jev-cost.json`: API-reported token totals, model revisions, and the estimated Jev cost.
+- Endform's automatically saved `run-*-ai-aria-snapshot.yml` files.
+
+Endform captures ARIA snapshots automatically after commands (including failures). The CLI saves them but only prints the command's stdout/stderr, so the controller reads the newly saved snapshot instead of calling `page.ariaSnapshot()` again. Screenshots are **explicit**: the controller calls `page.screenshot()` in the worker's current directory, and Endform transfers the new PNG back automatically. The controller groups copies under `screenshots/`. Screenshots and snapshots are sequential observations, not an atomic capture of an animating page. Capturing screenshots also adds latency to the loop.
+
+Cost is estimated at $0.042 per million input tokens and $0 for output tokens, using [TypeSafe's published pricing](https://typesafe.ai/blog/introducing-system-one-models-and-jev), checked September 22, 2026. Selection/completion requests count; this variant makes no execution-gate requests. Missing usage (including failed API requests) is flagged as a partial estimate. This estimates Jev API charges only, excluding Endform/browser infrastructure, and is not an invoice.
+
+The contextual gated baseline is recorded in `BENCHMARK_RESULTS.md`. The separate no-gate comparison is recorded in `BENCHMARK_RESULTS_NO_GATE.md`. The screenshot and stepwise comparison, with its fault matrix, is recorded in `BENCHMARK_RESULTS_IMAGES.md`. The naive Clairic loops are compared with the naive Jev loop in `BENCHMARK_RESULTS_CLAIRIC.md`. Every variant keeps the 30-iteration and seven-minute limits and the repetition guard.
