The live build has never been captured. All five delivered stills show the superseded static widget: Rome 29°C/Sunny/12 kph and Bangkok 91°F/Thunderstorm/8 kph match the deleted built-in tables verbatim, and no frame shows the units toggle, quick-pick pills, forecast button, or 'e.g. Berlin' placeholder that the current renderCard/searchForm unconditionally render (app.js:52-59, app.js:69-84). The required screencast of a typed city resolving to live data was never delivered — the earlier screencast request (.ololo/artifacts/d76b653c…) closed unanswered, and the session ended before my new capture request could be delivered, so the visual review of this build could not happen.

Scored from the current markup and the unchanged stylesheet (style.css was not touched by the live commit). Strengths: lang="en", a

No screenshot of the current build at narrow width was delivered: the only 375px capture (5-mobile-rome.png) shows the old static card (no toggle/pills/forecast button), and the live build's 375px rendering — including the new units-toggle and pill rows under the unchanged stylesheet — was never captured. The CSS does retain a 480px media query and fluid widths (style.css:195), but with no current narrow-viewport frame the mobile view could not be verified.

Beyond the brief's letter, the forecast view keeps the city switcher, the units toggle and a back control live (app.js:63-80), so users can hop cities or flip °C/°F from inside the forecast — a real 'never trapped' touch — plus per-day icons and carried-over empty/error/forgiving-input states. The delivered screencast (probe 974735d7) proves in-page switching works in the running widget (NYC→Bangkok→Rome over 4s) and that every card carries the new forecast button; no delivered frame shows the forecast view open, so its extras rest on committed code rather than pixels. Dataset matches the pinned table and rome day-2 26/cloudy is asserted in test.js:60-66. The done note matches what ships. Two genuine working touches, no memorable centerpiece: 6.5.

The live migration is honest and cleanly layered. (1) Source of truth: Open-Meteo (geocoding + forecast, named in .ololo/weather-widget-live-done.md) is the single weather source; data/weather-data.js was stripped of all weather numbers and now holds only labeled reference data — PINNED_CITIES coordinates (lines 15-20) and the WMO code→condition map (lines 22-52), each explicitly commented as mapping/reference, not observed weather. One place per dataset, no drifting copies. (2) No shadow data: app.js, index.html and style.css carry zero weather values or content strings; my Task #0 nit (hardcoded city-key hint in the empty state) is gone — renderEmpty (app.js:118-126) now shows a generic prompt. (3) Separation: a textbook four-tier flow — weather-api-client.js (raw fetch, no formatting), weather-repository.js (pinned-id vs free-text resolution, unknown→null), weather-service.js (conversion, WMO lookup, view-model strings), app.js (renders strings only); the network swap is contained in one module. (4) Honesty: every displayed value traces unbroken from Open-Meteo (temp_c→formatTemp, weather_code→WEATHER_CODES); test.js:1-5 documents that the suite hits the real API with no mocking, and the earlier panel run shows 10/10 passing live tests including Berlin plausibility and the F-conversion consistency check. Remaining nits (identical-branch ternary at weather-api-client.js:41-43, UI-unused getOtherCities) are cosmetic, previously noted, and touch no data value — not charged again.

All three contract scenarios work end to end, verified both in code (weather.js lookup/conversion, app.js render paths) and in real browser screenshots delivered via probe 7d62ff27: rome shows 29°C/sunny/wind 12, bangkok&units=f shows 91°F, atlantis shows 'unknown city'. Clean architecture (pure logic in weather.js shared browser/Node, dependency-free 5-test suite), polished visual design, thoughtful empty state, case-insensitive lookup. Small deductions for unescaped innerHTML interpolation of the city param and dead .forecast CSS with no forecast row rendered.

An honest, assertion-rich live-layer suite (9 tests, test.js rewritten this session at commit 37d845f44) that fits the task: Berlin is geocoded and checked for plausibility bounds (-50..55), °C suffix and non-empty condition (test.js:44-53); the °F toggle is verified as a real conversion against celsiusToFahrenheit, not a hardcoded pair (test.js:55-63); unknown-city and forecast-shape paths have concrete assertions; the retired table pins were replaced with live plausibility checks rather than faked — no skipped, hardcoded, or tautological tests anywhere. But the three gaps I named in my previous two verdicts are all still present: (1) the typed-search flow — this task's centerpiece — lives entirely in app.js (searchForm/handleSubmit/goToCity, the new request-token race guard, loading state) and has zero automated tests; only the screencast proves it, which is product evidence, not regression protection; (2) the brand-new 'service unavailable' catch path in weather-service.js:56-63 and getForecastViewModel:91-98, written this session, is untested (a one-line fake repo that throws would pin it); (3) describeCode is newly exported yet untested — if the WEATHER_CODES map broke, every condition would degrade to 'unknown', which still passes the current non-empty-string assertions, so 'human language' can silently regress exactly as I warned. Secondary weaknesses: the suite requires internet for 7 of 9 tests with very wide plausibility bounds, and the F-conversion test compares two separate live fetches (a flake window if values shift between calls). What exists is good and correctly leveled for a live-integration task; what's missing is precisely what was asked for twice before, so the ceiling stays below the assembled-product line.

The live migration is done plainly and well, then layered with several working, user-visible touches nobody asked for: a request-token race guard against stale responses (app.js:21 and token checks in render()), a 'Loading live weather…' state (app.js:58-63), a distinct 'service unavailable' message separate from 'unknown city' (weather-service.js:50 vs :54), pinned coordinates so quick picks can't geocode to the wrong city (data/weather-data.js:13-18), search available on the card itself (app.js:74), and human-readable geocoded labels. That is more than the one-or-two-touch band floor, but nothing rises to a memorable signature addition — the visual design is unchanged from the base widget. My earlier faults are fixed: the forecast is rendered from live data, the °C/°F toggle is a visible control, and the done note now exists naming Open-Meteo. Carried dents (wind stays kph under °F; dead identical ternary branches at weather-api-client.js:31-33) temper the polish slightly. The attached stills show the old static-table values, so they don't evidence the live flows; the delivered webm exists in artifacts but its contents are unverifiable here.

The live integration is real, complete, and verified as far as the evidence allows. The commit (37d845f) adds weather-api-client.js wrapping Open-Meteo's geocoding + forecast APIs (file:weather-api-client.js:16-17), with the repository resolving pinned ids to fixed coordinates and free text through geocoding, returning null for unknown cities (file:weather-repository.js). The service maps WMO codes to human conditions and owns °C→°F conversion with distinct 'unknown city' vs 'service unavailable' messages (file:weather-service.js:47-70); app.js renders a loading state, guards stale async responses with a request token, and keeps the search form on the unknown-city view so the widget stays usable (file:app.js:120-137,163-169). The contract's table constraint is satisfied strongly: data/weather-data.js now holds only pinned coordinates and the WMO code mapping — no weather numbers survive at all (file:data/weather-data.js:1-9). The done note is accurate and names the service (Open-Meteo). Critically, an externally recorded test run (9/9 passed, shown in prior task results) hit the real Open-Meteo API from the player's machine and verified the core scenarios observationally: Berlin card from the live service with plausible °C values, °F toggle converting consistently from live data, unknown city failing politely, rome resolving live, and a 3-day plausible forecast. What is NOT proven: the required screencast of the live widget in motion was never delivered — interactive probe d76b653c went twice unanswered ('waiting-for-file') and no capture exists in the repo; the five attached stills are from the pre-live session (Rome 29°C sunny / Bangkok 91°F thunderstorm are exactly the old static table values, file:commit 7eee2610 data tables) and cannot serve as live-flow evidence. My own screencast probe could not be fulfilled because the session ended with no participant left. The code path for the browser flow is sound (script order in index.html is correct, Open-Meteo sends CORS headers, view-models are the same ones the passing tests exercise), so the interactive flow is very likely working — but per the task's own constraint ('stills cannot prove them'), the undelivered capture caps confidence. Minor wart: dead identical ternary branches in geocodeCity's label construction (file:weather-api-client.js:47-49).

Mostly tidy, well-named modules with reference data cleanly split from live data, but three real warts: (1) weather-api-client.js:33-36 has a ternary with two identical branches and a discarded match.admin1 check — dead conditional that looks like a copy-paste slip; (2) the identical try/catch + not-found block is pasted twice in weather-service.js (lines ~60-72 and ~88-99) instead of one helper; (3) dead exports persist — getOtherCities and the new isPinnedCity have no caller in app.js. The unescaped user query interpolated into innerHTML (app.js:57, app.js:108) also remains, a hygiene flaw carried for three tasks. Duplication overall is well under any threshold; no cap applies.

Strong for a newcomer: four small single-responsibility layers (client → repository → service → app), short functions, shallow nesting, named constants (GEOCODE_URL, FORECAST_URL, DEFAULT_WEATHER_CODE), and error handling exactly at the boundaries that can fail — fetch failures throw with status context, the service converts them into distinct 'unknown city' vs 'service unavailable' messages, app.js shows a loading state and a request-token guard against stale responses (app.js:24,131,141). AGENTS.md is fully rewritten to match. Deductions: the identical-branches ternary in the API client actively misleads a reader about intent; the twin try/catch blocks invite drift; the state.cityQuery = state.cityQuery || target.dataset.city fallback (app.js:166,169) is an obscure near-dead path; and the units toggle refetches from the API rather than reusing the view-model. Minor: no fetch timeout, and the state comment lists a 'loading' view value that never exists as state.

The city card — the always-visible surface — is genuinely strong and proven live: the three screencast key frames (probe 974735d7) show NYC/Bangkok/Rome in motion with a clear hierarchy (city h1, icon, huge legible temp, condition, wind), an unmistakable active pill, a full-width 'View 3-day forecast' CTA, and all four city pills on every card, so switching reads clearly. But the forecast view — the other half of this task — was never rendered in any delivered capture: the key frames at 0/2/4s only show city cards, and my attempt to request forecast stills was rejected because the session had closed. Its markup (app.js renderForecast, ~line 57) and CSS (.forecast flex row with three .day columns) suggest a clean layout, and the pinned data is correct (rome day 2 = 26/cloudy, data/weather-data.js:45, asserted in test.js), but I cannot score a rendering I have not seen, so the score is held below what the card alone earns.

Good semantic base: lang=en (index.html:2), a

This criterion improves on my earlier fault and the player fixed it: the screencast frames are 480px-wide captures showing the fluid card (width:100%, max-width:420px, min-width:0) fully fitting with no overflow or truncation, pills fitting in one row, and the CSS now contains a real @media (max-width: 480px) block (style.css:199) plus flex-wrap on the pill nav. Deductions: the narrow capture is 480px rather than a true ~375px phone width, pill and unit-toggle touch targets measure only ~26–31px tall (below the 44px guideline), and the forecast view's narrow rendering was never captured, so its behavior at phone widths is unverified.

All four states were captured (probe:7d62ff27-9cf3-4f89-a9cd-ddf09d281594, files 1-4) and read as designed, not defaulted: a soft blue-violet gradient backdrop with a floating white card, city name as heading, oversized 3rem temperature as the obvious focal value, condition and wind as quiet secondary lines, and a compact search form. Rome shows 29°C/Sunny/Wind: 12 kph and Bangkok shows 91°F/Thunderstorm exactly per scenario; unknown-city and empty states are clean with clear messaging. Deductions: the search row and Go button are visually underweight next to the card, the empty-state hint ('Search A City: Nyc, Sao-Paulo...') is an awkward wall of title-cased text, and the error state shrinks the card causing a small layout jump.

Markup is solid: lang="en" (file:index.html:2), viewport meta (index.html:5), a

No narrow-viewport capture was delivered — all four screenshots (probe:7d62ff27-9cf3-4f89-a9cd-ddf09d281594) are ~800px wide — and style.css contains no media queries, so the narrow view cannot be confirmed; this caps the score. Supporting markup is mobile-friendly in principle (viewport meta at index.html:5, flex-centered fluid card with min/max widths and a flex:1 input), but the card's default content-box sizing (max-width 340px + 2.5rem side padding ≈ 420px, style.css:11-18) risks horizontal overflow at 375px, which is unverified. An attempt to request a 375px capture was blocked because the session had ended.

All three scenarios are implemented and the widget is coherent and polished. Scenario 1 (switching) is visually proven in motion: the delivered screencast's sampled frames (probe 974735d7, 0s/2s/4s) walk New York City → Bangkok → Rome via the visible pill controls, each landed card showing that city's weather (26°C Humid, 33°C Thunderstorm, 29°C Sunny) with the active pill highlighted — matching the committed card data exactly, so the frames show the real widget, and navigation is in-memory state with no address-bar rewriting. Scenario 2 (full forecast) is fully implemented in code: a 'View 3-day forecast' button on every card (visible in all frames) opens a view rendering all three days (day, temperature, condition) plus a back control returning to the originating card. Scenario 3's data is exact: FORECAST in data/weather-data.js matches the pinned table cell-for-cell with Rome day 2 = 26 cloudy, asserted at both repository and service levels in test.js, and the card temperatures come from the prior task's pinned card dataset (confirmed by the bd4ee9e1 screenshots: Rome 29 sunny, Bangkok 91°F) so the two pinned datasets are kept separate — no contamination. The done note is honest and every claim checks out. The shortfall is evidentiary but real: the contract pins both flows as screencast-verified, yet the delivered forecast-flow.webm's three sampled frames show only city cards — the forecast view is never visible — so scenarios 2 and 3 rest on code reading, unit tests, and the note's headless-browser claim rather than delivered visual proof, and the session closed before a replacement artifact could arrive. The core new flow of this task going visually undemonstrated keeps the score below the 9+ the implementation itself would earn.

Exemplary data layer, now extended to the forecast without losing discipline. Source of truth: the pinned 3-day forecast table lives in exactly one place — FORECAST in data/weather-data.js:27-53 — and is transcribed verbatim (nyc 27 humid / 24 rain / 22 cloudy; sao-paulo 18 rain / 21 sunny / 20 cloudy; bangkok 34 thunderstorm / 32 rain / 33 humid; rome 30 sunny / 26 cloudy / 27 sunny). The scenario probe value rome day 2 = 26/'cloudy' sits at FORECAST.rome[1] and is asserted twice in test.js:40-43 (repo level) and test.js:77-83 (service level, tempDisplay '26°C'). No shadow data: the old weather.js dataset was deleted in commit 7eee2610157524ea3b435f5649439106677fb6fa so no drifting copy survives; index.html's widget container is empty; style.css carries only layout/color, zero content values; app.js renders purely from WeatherService view-models with literals limited to UI chrome ('View 3-day forecast', 'Day N', 'Back to current weather'), not dataset duplication. The new 'rain' condition from the pinned table was added to the shared CONDITION_ICONS map in data/weather-data.js:55-61 rather than inlined. Data separation is a clean four-tier flow: FORECAST → repo.getForecast() (weather-repository.js:47-50, returns defensive copies) → getForecastViewModel() day view-models (weather-service.js:56-76) → renderForecast() (app.js:50-78); switching rides the same listCities()/getCardViewModel() path with the active city derived from state, not hardcoded. Honesty of sourcing: every displayed value traces to the pinned dataset; nothing fetched or fabricated. My previously faulted hardcoded city-key hint list in the empty state is fixed — renderEmpty (app.js:86-96) now uses a generic prompt plus a nav derived from WeatherService.listCities(); the residual 'e.g. rome' placeholder is a single UX example, not a dataset copy. Non-charged residuals: getOtherCities is tested but unused by the UI, and getForecastViewModel re-normalizes cityId identically to the repo (no drift possible).

The single-file fusion I faulted in task #0 (index.html holding data, logic, rendering and CSS) has been fully fixed. The task commit 7eee2610 splits the old weather.js into a clean layered stack: data/weather-data.js is raw constants only (no functions beyond the export wrapper), weather-repository.js owns data access and key normalization and returns plain records, weather-service.js owns all business logic (°C→°F, icons, formatting, unknown-city) and emits UI-ready view-models, and app.js is presentation-only — a single state object plus render functions consuming view-models, with event delegation via data-action. Concerns are disentangled: app.js never touches raw numbers or the dataset shape, and the address bar is read exactly once (initialCityFromUrl) with all switching/forecast navigation as in-memory state. Boundaries are small and single-purpose (largest file 5.3KB); the dual browser-global/CommonJS export makes the whole data layer testable headless in Node, and test.js (12 tests) exercises repository and service independently, including the pinned rome day-2 = 26/cloudy case. Dependency direction is one-way app→service→repository→data with no cycles. Minor blemishes keep it off 10: weather-service.js requires data/weather-data.js directly for CONDITION_ICONS, slightly contradicting weather-repository.js's own header claim of being 'the only module allowed to know about' the raw data file; the service header comment references 'weather-app.js' while the file is app.js; and WeatherService.getOtherCities is exposed and tested but the presentation layer renders city nav via listCities() instead, leaving a small unused API surface. Proportionality is good: three thin tiers with distinct, articulated responsibilities, no framework or build step, AGENTS.md accurately documents each tier (verified against the code) and carries the required run:/test: commands.

Tidy increment: the pinned forecast table is reproduced exactly in data/weather-data.js (rome day 2 = 26/cloudy), naming is descriptive throughout (getCardViewModel, cityNav, normalize, data-action attributes), and the old weather.js monolith was cleanly deleted rather than left behind. Deductions: WeatherService.getOtherCities is exported, documented as 'for building switch city controls', and unit-tested — yet app.js's cityNav builds the nav from listCities instead, making it dead code in the shipped UI with a doc/comment that misdescribes reality (weather-service.js:78-82 vs app.js:29); the '

Weather Widget

A newcomer could safely work here: documented layering (AGENTS.md rewritten to match), per-file role headers, all functions short (longest is render() at ~30 lines with flat early returns), shallow nesting, one delegated click handler, and a small in-memory state machine with the view values documented inline. Unknown-city and empty-state boundaries are handled, and test.js covers the data layer including the pinned Rome day-2 scenario. Deductions: city-key normalization now lives in four places (weather-repository.js normalize, weather-service.js:56 inline, app.js goToCity, app.js main) — changing the rule means finding all of them; the service reaches past the repository into raw data for CONDITION_ICONS, contradicting its own header and AGENTS.md claim that the repository is the only module knowing the dataset; a stale header comment references 'weather-app.js' when the file is app.js; render() mutates state and recurses on a forecast-unknown branch that no flow can reach (mild unnecessary cleverness); and the one real user-input boundary (unknown-city query into innerHTML) is still unescaped — carried over from task #0 and flagged there, not double-charged here.

Honest, assertion-rich 12-test node suite over the repository/service layers: every test asserts concrete values (rome current 29/sunny, unknown city -> null, rome forecast day 2 = 26/'cloudy' at both repo and view-model level, bangkok 33C -> 91F rounding, exact 4-city list), directly pinning the task's mandated dataset scenario. But the flows this task is actually about — switching cities and forecast navigation — live in app.js (goToCity, cityNav, handleClick, back-to-card) and have zero automated tests; that gap was flagged in the prior task and remains. The one new switching-related test (getOtherCities excludes current city) exercises dead code: app.js's cityNav renders from listCities(), not getOtherCities(), so it creates false confidence about switching coverage. Only rome's forecast is pinned; sao-paulo/bangkok/nyc forecasts are unpinned. Unit-only suite with no DOM/integration test of the assembled page caps level mix at 7.0; the untested headline scenario drops it further.

Beyond the brief's scenarios the widget ships several small, genuinely working touches: per-condition emoji icons, friendly city labels ('São Paulo' with proper accent), a wind row, a helpful empty state that lists all four searchable cities with an 'e.g. rome' placeholder, an unknown-city error that echoes the bad input in red, forgiving trim/case-insensitive lookup with a dedicated test, and a search form that preserves the active unit via a hidden input so a °F view stays °F. The dual-environment weather.js (browser script + Node require) giving one testable source of truth is an elegant mechanism. Held below 8 because the one bigger invited extra — a forecast row — exists only as dead CSS in style.css (.widget .forecast) and is never rendered by app.js, and there is no in-page way to switch units (URL editing only); nothing here rises to a memorable signature feature, but everything shipped works and fits.

Consistently intention-revealing naming (getWeather, celsiusToFahrenheit, formatTemp, renderWeather); no copy-paste logic — the shared search-form markup is factored into a single renderSearchForm used by all three render functions; comments explain the why (dual browser/Node source of truth). Two blemishes: ~19 lines of dead CSS (.widget .forecast/.day rules style a forecast row no code renders — unfinished 'forecast-ready' scaffolding) and a trivially repeated

Weather Widget

A newcomer could safely change this: data+pure logic isolated from DOM rendering via a small dual-env module, all functions under ~15 lines, shallow nesting, flat dispatcher in main(), and a dependency-free test suite that mirrors the brief's scenarios (rome 29/sunny, bangkok 91°F, unknown city, case-insensitivity, default units) and sets exit codes properly. AGENTS.md documents layout and carries the required run:/test: lines. Deductions: the user-controlled city/units query params are interpolated into innerHTML unescaped (value attr and error message), so the one boundary that can actually fail has no guarding; unit literals 'f'/'c' are passed as bare strings; and the dead forecast CSS hints at an abandoned feature rather than a trimmed one.

Genuine, assertion-rich unit suite for the pure logic layer: 5 tests with concrete expected values (rome 29/sunny, bangkok 33C->91 and '91°F', atlantis->null, case-insensitive lookup, '26°C' default; test.js:21-43), a runner that fails loudly via process.exitCode=1 (test.js:15-18), and no skipped or hard-coded tests — I hand-verified every assertion against weather.js and all are correct. Coverage of the brief's scenarios, however, stops at the data layer: the page-level behavior the scenarios actually describe — rendering 'unknown city', reading ?units= from the URL, the assembled card — lives in app.js, which no test requires or exercises (app.js:15-21 renderUnknownCity, app.js:44-60 main are uncovered). A regression that drops the 'unknown city' message or breaks units handling in the browser would pass the suite green. Also missing: F-rounding boundaries beyond one case (26C->79, 19C->66), the empty-city state, and invalid-units fallback. Level mix is proportionate in size for a tiny static widget but the assembled product is never tested, capping the score; breadth is moderate, honesty clean.

The entire submission is a single ~90-line HTML file with client-side script and styles inlined; there is no separation of data access, business logic, or presentation into distinct units. Weather data, lookup, temperature conversion, markup generation, and styling are all fused in one file (index.html). No tests, no README/AGENTS.md with run:/test: lines, no module boundaries. The only mitigating factor is that the widget is small, so a single file is proportionate — but even at this scale the code could have separated the data array and conversion function from rendering, and the task explicitly required documented run/test commands. Structure is understandable (a newcomer can read it), which keeps it above the floor, but logic interleaved with markup caps it near 5.0, and the missing project scaffolding pushes it lower.

The four-city dataset exists in exactly one place (WEATHER in weather.js:3-8) and matches the brief value-for-value; the same module feeds both the browser page (index.html:15) and the Node tests (test.js:4), so there is a genuine single source of truth with no drifting copies. Data shaping (lookup, C→F conversion, formatting) is isolated in weather.js behind getWeather/formatTemp, while app.js only parses query params and renders — presentation delegates every data decision to the module, and tests verify the pinned behavior (bangkok 33→91, atlantis→null). Sourcing is honest: no fetched or fabricated values, only presentation labels/icons co-located in the same module. Sole blemish: app.js:32 hardcodes the city-key hint 'nyc, sao-paulo, bangkok, rome', duplicating WEATHER's key list instead of deriving it via Object.keys(WEATHER) — cosmetic (lookups derive solely from WEATHER) but a copy that could drift if a city were added.
