The task's product was not built: the feat commit 51b8a1bb is empty, the required .ololo/weather-widget-live-done.md does not exist, and no code changed in the work window. The widget still serves the four quick picks from the static table in src/data/cities.js ('The widget's entire weather source'), so Scenario 'Quick picks go live' is explicitly violated. Scenario 'Typing a city name' is impossible — no search form or text input exists in any view (cityPickerPage and cityList are link-only), and getWeatherReport returns null for any city outside the table with no network call anywhere (package.json has zero dependencies). The required screencast artifact was never requested or delivered. The single point of credit goes to the inherited, still-working polite unknown-city page, which was built and scored in a prior task — it is not this task's work.

No architectural work was done for this task: the work-window diff is empty and telemetry shows no tool calls. The one boundary the task existed to create — the core declaring a weather-source port that an edge adapter implements against a real live service, with plain-data contracts and failure mapping — was never introduced. The core still sources weather from the frozen built-in table, which the code itself labels 'the widget's entire weather source', the opposite of the required structure. No score below this because the pre-existing skeleton did not regress (it remains framework-free and unit-testable, which would have made the live seam easy to add), but crediting that structure again would double-pay a verdict already given last task; previously noted polish items (°C labels in the domain, top-level naming) are unchanged and not re-charged.

No work product exists for this task: the diff from the task's start commit (0241138) to the task commit (51b8a1b) is completely empty, no weather service integration was added (src/data/cities.js:2 still declares the built-in table 'the widget's entire weather source'), and the required .ololo/weather-widget-live-done.md is absent. Nothing was written, so there is nothing clean to credit; the inherited codebase's quality was already scored in the prior tasks and is not re-charged.

The task's only new boundary — a real network call that can fail, time out, or return garbage — was never built: src/domain/weather.js and src/app.js still read exclusively from the frozen built-in table and package.json gained no network client. A newcomer cannot change or extend a live integration that does not exist; the required done marker naming the chosen service is missing at the task commit.

Nothing was built for this task. The work-window diff is empty, .ololo/weather-widget-live-done.md is missing, and src/domain/weather.js still serves only the four hardcoded cities from src/data/cities.js — there is no weather service, no HTTP fetch anywhere in src/, and no input for typing an arbitrary city name. The core scenarios (live search, live quick picks) visibly do not work, which caps any extra-mile credit at 4.0; and in fact there are no new extras at all to credit — the pleasant touches (picker, unit toggle, themes) are unchanged prior-task work already scored in my earlier verdicts, so they are not charged again. Score reflects an untouched codebase against a brief that asked for a real new capability.

no screenshot delivered — and nothing to capture: the work-window diff is empty, so no new user-facing surface exists to review

no screenshot delivered — no narrow-viewport capture exists and no CSS changes were made this task to assess

The task's entire data requirement went unimplemented. The work-window diff (4ec6db5..51b8a1bb) is empty — the feat commit contains no changes — and the current source still names the static table as 'The widget's entire weather source' (src/data/cities.js:1), with every displayed value derived from it (src/domain/weather.js:19-41). No weather service is wired in anywhere: app.js maps requests without touching the network by explicit design comment (src/app.js:16), there is no fetch/API module in the tree, and unknown cities 404 rather than being looked up live. The built-in tables are therefore still the source of truth, which the task explicitly forbids ('no longer the source of truth'; they may survive only as a clearly labeled fallback — not even a fallback label exists). One point above the floor only because the pre-existing data layer remains cleanly separated and nothing was fabricated: the app honestly serves exactly its static dataset and invents no live values. But for this task the honesty-of-sourcing requirement — output derived from a pinned live source — is simply absent, not met.

All three brief scenarios are implemented exactly as specified and verified against the code. (1) Switching: every rendered page includes a 'Cities' switcher whose links are built by routes.js href(), keeping the current view and units, and landing pages show that city's own weather (pages.js weatherPage/forecastPage). (2) Forecast: each card has a '3-day forecast' strip linking to /forecast?city=; the forecast page lists all three days with label, icon, condition and temperature, and 'Back to ' returns to the originating card (components.js forecastCard). (3) Dataset: src/data/cities.js forecast rows match the task table city-for-city — 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 — so rome day 2 reads 26 and 'cloudy', asserted in test/navigation.test.js. The verification is strong: probe logs .ololo/probes/0044-tests.log and 0045-tests.log show 47/47 passing, and the navigation tests follow the real hrefs parsed out of the rendered HTML (every city to every other city, card→forecast→back for all four cities, units persistence, unknown-city on /forecast) rather than hardcoding URLs — since the flows are plain hyperlinks with no client-side JS, HTTP-level link-following is close to real browser behavior. The widget was kept running (.ololo/server.log, port 3030), and the done note's claims all check out against the code, including the new rain icon/theme and the port correction to 3030. What keeps this below the top band: the task contract names a screencast of the running widget as the way to verify the living flows, and no screencast exists — I registered an interactive probe for one (Rome→NY→São Paulo→Bangkok, forecast open, Rome Day 2 readable, back to Rome) but the platform refused it because the participant had already moved on, so the visual/motion layer (CSS cross-document view transitions, actual rendered composition, headless-Chrome click-through claim) rests on code reading, tests and my prior task-#0 verdict rather than direct observation. Judgement calls (Day 1–3 labels because the dataset has no dates, forecast switcher keeping the forecast view, aria-current highlighting) are all coherent with the task's intent.

The dependency rule holds and was preserved through the growth. The domain remains framework-free: src/domain/weather.js imports only the frozen plain dataset and wind.js, and now owns the forecast rule (day numbering, unit conversion, rounding) as a pure mapping (src/domain/weather.js:32-44). The app layer is still a pure (method, rawUrl) -> {status, headers, body} function with node:http confined to src/server.js (src/app.js:33, comment 'without touching the network'). The single new seam this task needed — two views ('card', '/forecast') behind one handler plus link building — was paid for with exactly one small module, src/routes.js, which imports only domain/units.js; views import href from it, so the dependency direction still points inward and nothing at the center names a request, a framework type, or the wall clock. Business rules and the living flows are testable alone: test/navigation.test.js exercises switching, the forecast, the return link, and the rome day-2 = 26/cloudy dataset check purely through handleRequest with regex-based link following (test/helpers.js) — no server, no browser — and probes 0044/0045 show 47/47 passing. Proportionate: no extra DTO rings or mirror interfaces were introduced for a two-hour task; CITY_PAGES in app.js and the view parameter threaded to shared pages are the minimum indirection the second view required. Residual minors, previously noted and not structural: display labels ('°C', tempSymbol) still live in the domain's UNIT_SYSTEMS (src/domain/units.js:8-9), routes.js sits at src/ root beside layered folders, and top-level naming is still generic (domain/, views/) rather than task-concept-first.

no screenshot delivered — probe registration failed ('participant has already moved on'), so the card, forecast view, picker and unknown-city surfaces were never seen rendered and the visual hierarchy cannot be judged

no screenshot delivered — contrast cannot be verified. Markup-side evidence exists (components.js: semantic article/ol/dl/nav, aria-current on the active city and unit, visually-hidden condition text next to icon-only tiles, aria-label on the forecast list, lang="en" in layout.js:12), but half the criterion depends on seeing the render, so the honest verdict is null

no screenshot delivered — no narrow-viewport capture exists. The stylesheet does contain mobile-first fluid rules (styles.css: .shell max-width, 2-column city tiles under 48rem, 44px --tap tokens, safe-area insets), but per the rubric that alone caps rather than proves the score, and with no render at all the criterion stays null

The new code is clean and consistent with the prior task's standard. The link builder moved out of components.js into a purposeful routes.js (VIEW_PATHS + viewForPath + href), and the old widgetHref was fully removed rather than left as dead code — AGENTS.md was updated to match. cardHeader was extracted once and shared by both card views instead of copy-pasting the header markup; forecastPreview and forecastCard map the same data differently (strip vs full list), which is not duplication. Naming is descriptive: viewForPath, forecastPreview, back-link, dayLabel. Nits: titleId is parametrized but always passed 'city-name', and the 'card' view default is repeated independently in href and cityList — trivial, no measured duplication, nothing pasted.

A newcomer could change this safely: every link in the app is built through one href() in routes.js, so view/units/city persistence is a single place to reason about; the handler maps views to pages via a plain frozen CITY_PAGES object and reuses the existing unknown-city/picker/404 flows for /forecast, all covered by tests (navigation.test.js follows the real links for every city, keeps units, and covers /forecast?city=atlantis 404 and bare /forecast picker). Functions stay short and shallow — the longest, forecastCard, is ~20 lines of template. Magic values are named (dayLabel, DEFAULT_UNITS, VIEW_PATHS), and even the 3030 port is documented with a reason in AGENTS.md. Persisting nitpick from my prior review, not re-charged: test helpers still parse rendered HTML with regex (test/helpers.js testIdText/links), which is brittle if markup structure shifts — but the helpers were consolidated into one file and the assertions read clearly. The forecast day testid ('forecast-day-${day}') is a sensible, greppable hook.

Beyond the required switcher/forecast/back flows, the build ships working extras: CSS cross-document view transitions that morph the weather card between cities while the city list stays put (no client JS, reduced-motion respected), a fully tappable 3-day forecast preview strip on every card, and view-aware links so switching cities inside a forecast opens the next city's forecast. Plus a rain condition theme, aria-current and screen-reader labels, and unknown-city/picker handling on /forecast. These are genuine, working, user-noticeable touches rather than gimmicks; the animated card morph is the memorable one.

The suite added for this task is strong and proportionate. Every scenario in the brief has a matching test with exact dataset values: navigation.test.js follows real links from each of the four cities to every other city and asserts the landed card's temperature and condition (file:test/navigation.test.js:18-21), opens the forecast for all four cities asserting all three days' day/condition/temp plus the back link landing on the original card (file:test/navigation.test.js:44-61), and pins the dataset check 'Day 2 cloudy 26°C' for rome (file:test/navigation.test.js:89-94). Coverage goes beyond happy paths: units kept while switching (exact href '/?city=nyc&units=f' and 79°F), Fahrenheit through the forecast and back (79°F = round(26*9/5+32)), city switching within the forecast view, unknown city on /forecast (404 + 'unknown city'), missing city → picker, aria-current marking, and card preview text. The domain forecast data is asserted with deep-equal including converted °F values (file:test/domain.test.js:52-64), and the prototype-key lookup regression guard remains. Level mix is right for this size: unit tests for conversion/lookup, request-level flow tests through real link text→href→page, and real-HTTP integration (server.test.js) — so the assembled product is exercised, not just units. Honest: nothing skipped or commented out; the two delivered probe logs (.ololo/probes/0044-tests.log, 0045-tests.log) show 47/47 passing with the exact test names present in the files, and the arithmetic checks out (30 prior − 1 renamed href test + 2 href tests + 1 forecast-domain test + 15 navigation tests = 47). The one residual nit is the regex-based HTML extraction in helpers (file:test/helpers.js:19-24), which makes some assertions brittle to markup nesting — the same nit I flagged in the prior task, still not addressed but harmless here. Tests do assert on href strings in a couple of places, but those are the widget's URL contract, not implementation details. A regression in switching, forecast data, units persistence, or error handling would all be caught.

The pinned forecast dataset lives in exactly one place: src/data/cities.js, the same Object.freeze'd source of truth established in the prior task, extended with forecast: [day(...)] arrays whose values match the brief exactly for all four cities (I verified each cell). No shadow data: components.js, pages.js, routes.js, styles.css contain zero baked-in weather values; every displayed number/condition is interpolated from the shaped report, and 'Day N' labels are derived from array index (documented in AGENTS.md as intentional since the dataset carries no dates — honest, not fabricated). Data layer separation is clean: forecast shaping (day numbering, unit conversion, rounding) lives in getWeatherReport in src/domain/weather.js; views only format; routes.js is pure routing/links. Sourcing is honest: nothing beyond the pinned dataset was invented — the prior version that declined to fabricate a forecast now uses exactly the one the brief pins. Rendered output is checked against the dataset module itself in test/navigation.test.js, and probe #45's 47 tests pass, including 'reads 26 and cloudy for rome day 2'. This fully builds on the data quality I credited in Task #0 with no regression.

The dependency rule holds throughout: src/domain/units.js and src/domain/wind.js import nothing, and src/domain/weather.js imports only the dataset and sibling wind.js — no framework, request, DB, or clock types in the core (src/domain/weather.js:1-2). The HTTP boundary is inverted correctly: handleRequest(method, rawUrl) -> {status, headers, body} is a pure function over plain data (src/app.js:22-38) and node:http is confined to an 18-line adapter (src/server.js:3-18), consistent with zero runtime dependencies in package.json. Business rules are testable alone — domain suites (units, weather reports, describeWind) pass with no server in the probe logs, and a separate thin suite covers the real socket. Boundaries are proportionate: a frozen plain-object dataset, no interface/DTO ceremony, and every seam (pure handler, view functions) is paid for and exercised. Small deductions: UNIT_SYSTEMS in the domain carries display labels ('°C', 'km/h'), and top-level naming (app/server/main) is infra-flavored though domain/{weather,wind,units,cities} do name the task's concepts.

no screenshot delivered — the visual review of the weather card, picker, and error surfaces could not happen, so visual hierarchy and readability cannot be assessed

no screenshot delivered — markup semantics look sound in code (lang attribute, aria-labelledby, aria-hidden decorative icons in src/views/icons.js, visually-hidden condition text in src/views/components.js), but contrast, the other half of this criterion, is judged from the screenshot, which was never provided

no screenshot delivered — the stylesheet shows media queries, fluid widths, a 44px tap token, and safe-area insets (public/styles.css), but actual narrow-viewport rendering (no overflow, no truncation) can only be verified visually, and no capture exists

The four-city dataset lives in exactly one place — Object.freeze'd CITIES in src/data/cities.js — with values matching the brief exactly, and every displayed value (temps, conditions, wind km/h, °F conversions, mph) is derived from it through a clean data→domain→view pipeline. No shadow or mock data ships: icons.js and styles.css only key presentation by condition name, wind.js's Beaufort scale is sanctioned added data (the brief allows 'wind'), and the stylesheet is read from public/styles.css rather than duplicated. Reading/shaping is fully isolated (parseUnits, normalizeCitySlug, getWeatherReport in src/domain; views only format what they're given). The lone duplication of dataset values is a test fixture in test/domain.test.js:36-44, a legitimate test oracle that cannot drift into the build. No fabricated data — AGENTS.md even documents the deliberate omission of a forecast row because the pinned dataset carries none.

No duplication and no dead code: all four pages reuse shared components (weatherCard, messageCard, cityList, unitToggle) and data tables (CITIES, UNIT_SYSTEMS, BEAUFORT_BANDS, CSS [data-condition] tokens) instead of pasted branches. Naming states intent everywhere (parseUnits, normalizeCitySlug, widgetHref, describeWind). Every export is consumed and tested. Minor deductions only: icon() silently maps unknown icon names to 'cloudy', masking typos, and no lint/duplication probe data exists (not needed — the ~600-line JS tree was read in full).

A newcomer could change this safely: handleRequest is a pure (method,url)->response function with a thin HTTP adapter, all functions are short (longest ~38 lines incl. comment), nesting stays at depth 2, and magic values are named (KM_PER_MILE, BEAUFORT_BANDS, CSS --tap/--radius tokens). Boundaries are covered: try/catch -> 500 in server.js, 405 for non-GET/HEAD, 404 for unknown paths/cities, Object.hasOwn prototype-safe lookups, auto-escaping html template with an XSS test, CSP header. AGENTS.md documents stack, layout, commands and conventions. The only comprehension cost is the regex-over-HTML testIdText helper in test/app.test.js, which breaks silently if markup shapes change — a small cleverness-for-brevity defect in the test suite, not the app.

A proportionate, high-quality suite for a small task: 30 tests across unit (domain), app (pure handleRequest), and real-HTTP integration levels. All three brief scenarios are asserted with exact expected values: 29/"sunny" for /?city=rome (test/app.test.js:12), 91°F for /?city=bangkok&units=f including wind 8kph→5mph (test/app.test.js:27-33), and 404 + "unknown city" for atlantis (test/app.test.js:43). Coverage goes well beyond the happy path: XSS escaping of the echoed city name (test/app.test.js:50), prototype-pollution-safe city lookup ('proto', 'constructor') and Beaufort band boundaries (test/domain.test.js:47,53), rounding of all four cities' converted values against the brief's table (test/domain.test.js:31), case-insensitive/whitespace-padded queries, unrecognised units falling back to Celsius, 404 paths, 405 methods, CSP headers, and HEAD-without-body over a live socket (test/server.test.js:26). Assertions are concrete (assert.equal/match on values, statuses, hrefs), not run-only. Honesty is clean: the delivered probe logs (.ololo/probes/0032-tests.log) confirm 30/30 passing with 0 skipped on three separate runs, matching the source files; the early 'no tests ran' logs are honest pre-test history. Minor deductions: the testIdText/visibleText regex extraction is brittle and mildly couples tests to markup shape (test/app.test.js:10), and the dataset-restate test ('reports every city') borders on restating rather than specifying — but here the dataset is the spec, so it verifies correctly.

The brief's scenarios are fully covered and then some. Working, user-noticeable extras nobody required: a city-picker page at '/' with a helpful empty state (src/views/pages.js:36-52); a city-comparison list showing live temperatures for all four cities on every page with aria-current marking (src/views/components.js:60-82); a °C/°F unit toggle that preserves the chosen unit when switching cities, verified by test 'keeps Fahrenheit when switching cities' (test/app.test.js:47-50); Beaufort-scale wind descriptions ('gentle breeze') with band-boundary tests (src/domain/wind.js, .ololo/probes/0032-tests.log); whole-page per-condition color theming via body[data-condition] with dark mode, reduced-motion, safe-area insets and 44px touch targets (public/styles.css:33-45); hand-drawn inline SVG icons per condition (src/views/icons.js); per-page title/meta showing 'Rome · 29°C sunny' (src/views/pages.js:7-9). A deliberate product judgment replaces the suggested forecast row with an honest live city comparison since the dataset has no forecast data (AGENTS.md Conventions). Also graceful 405/404 pages, case-insensitive matching, CSP + auto-escaping template with an XSS test. Multiple genuine, working, fitting touches — several solid extras rather than one showstopper, so top of the 6-8 band rather than 8.5+.

All three scenarios verified by hand in the code: getWeatherReport (src/domain/weather.js) rounds units.temperature(tempC), so /?city=rome shows 29/'sunny' and /?city=bangkok&units=f shows round(91.4)=91; unknown cities return null → 404 with a page containing 'unknown city', offering the four known cities and escaping the echoed query (test/app.test.js 'escapes the echoed city name'). Three committed probe runs (.ololo/probes/0014, 0029, 0032) show 30/30 tests passing via npm test. Beyond the contract the widget adds taste that serves the visitor: a city picker with live temperatures, a °C/°F toggle that preserves the choice across city links (widgetHref), Beaufort wind descriptions, per-condition colour themes, dark mode, 44px touch targets, and a restrictive CSP — all with zero dependencies and no client-side JS. Judgement calls are documented honestly in AGENTS.md (no forecast row because the dataset has none). Minor deductions: data-testid attributes left in production markup, and the rendered look is verified from code + structure tests rather than a live screenshot.
