The team breakdown page rendered a 5-column table that overflowed on
phones, forcing horizontal scroll. Add a responsive card layout for
mobile that shows every field (pick #, sport, participant, position,
points) with no horizontal scroll, while keeping the existing sortable
table on desktop (md+).
- Header now stacks on mobile (flex-col -> sm:flex-row).
- Mobile renders one card per pick with a compact sort control (field
select + asc/desc toggle) instead of clickable column headers.
- Extract shared PositionCell / PointsValue / pickLabel helpers so the
table and cards stay in sync.
- Update tests to scope table assertions and cover the mobile view.

The previous fix only queried playoffMatchGames.scheduledAt for bracket
events. FIFA World Cup group stage matches live in groupStageMatches
(linked via tournamentGroups), not playoffMatchGames. Now
getUpcomingScoringEvents fetches both tables in parallel and uses
the earliest scheduledAt from either source as earliestGameTime,
matching what UpcomingCalendarPanel already shows on the Upcoming Events page.

getUpcomingScoringEvents already fetched per-game scheduledAt times from
playoffMatchGames for sorting, but discarded them from the return value.
EventSchedule was showing eventStartsAt (event-level) instead of the
accurate per-game times. Now getUpcomingScoringEvents includes earliestGameTime
in each returned event, and EventSchedule prefers earliestGameTime over
eventStartsAt — matching how UpcomingCalendarPanel works on the Upcoming Events page.

## Summary
- Adds `useHasMounted` hook (using `useSyncExternalStore` — no extra render cycle) to gate UTC timestamp formatting to client-only
- Fixes the visible time-flip in `EventSchedule` and `UpcomingCalendarPanel` where SSR rendered UTC time (e.g. "9:00 PM") and the client re-rendered with local time (e.g. "2:00 PM PDT") after hydration, with `suppressHydrationWarning` silently hiding the mismatch
- Fixes `formatEventDate` in `date-utils.ts` (and `EventSchedule`'s private copy) to parse `YYYY-MM-DD` strings as local midnight instead of UTC midnight, correcting an off-by-one day bug for UTC-negative users across all callers
## Test plan
- [ ] Navigate to a sports season page — confirm event times show in local timezone with no flash/flip on load
- [ ] Hard-reload the page — confirm no brief UTC time visible before settling on local time
- [ ] Check the home page `UpcomingCalendarPanel` — confirm same behavior
- [ ] Verify dates display correctly (e.g. no "Jun 17" showing for a "Jun 18" event near midnight UTC)

## Summary
- 0-3 teams in Stage 3 were being assigned slots 9–10 (high QP) when marked eliminated before other Stage 3 teams, because `computeStage3ExitQP` filled from slot 9 upward using only the teams passed in
- 1-3 teams had the same problem when marked before 2-3 teams
- Fix: gate all Stage 3 QP computation on `stage3Exits.length === STAGE3_TOTAL_EXITS` (8) — partial saves write 0 QP as a placeholder, and correct QP/placements are assigned once all 8 exits are known
- As belt-and-suspenders, `computeStage3ExitQP` now places 0-wins teams from the bottom of the slot range so the function itself is correct even if called with a partial set
## Test plan
- [ ] Run `npm run test:run -- app/models/__tests__/cs2-major-stage.test.ts` — all 17 tests pass
- [ ] Mark 2 Stage 3 teams as 0-3 eliminated and save — confirm they show 0 QP (not 2 QP)
- [ ] Mark all 8 Stage 3 exits and save — confirm 0-3 teams get slots 15–16 QP, 1-3 teams get slots 12–14 QP split correctly

## Summary
- Deletes 12 `it("calls onX with correct args")` test blocks from `MiniDraftGrid.test.tsx` and `DraftGridSection.test.tsx`
- Removes now-unused `import userEvent` from both files
## Why
`userEvent.setup().click()` hangs indefinitely on Radix UI `ContextMenu` items in jsdom — pointer-event and animation checks stall waiting for CSS transitions that never fire `transitionend` in the test environment. This caused a flaky 5 s timeout in CI.
The deleted tests were verifying that clicking a `ContextMenuItem` fires its `onClick` — React/Radix wiring, not app logic. The remaining presence/absence tests already cover the conditional rendering (which items appear under which conditions), which is where the actual app logic lives.
## Test plan

## Summary
- Removes the last in-process \`setInterval\` (\`server/snapshots.ts\` 24h loop) and replaces it with an external HTTP cron job via Forgejo Actions
- Adds automated standings sync + conditional simulation: syncs every 2h, only simulates when standings actually changed (detected by comparing \`gamesPlayed\`/\`leagueRank\` before upsert)
- Adds \`GET /healthz\` for Docker healthcheck (Phase B prerequisite)
## What's new
| Endpoint | Triggered by | What it does |
|---|---|---|
| \`POST /admin/jobs/run-daily-snapshots\` | Forgejo schedule \`5 0 * * *\` | Creates daily fantasy standings snapshots for all active/draft seasons |
| \`POST /admin/jobs/sync-and-simulate\` | Forgejo schedule \`0 */2 * * *\` | Syncs standings from external APIs; runs simulation only if standings changed |
| \`GET /healthz\` | Docker / Traefik | Returns 200 \`{ok:true}\` when DB reachable, 503 otherwise |
Both cron endpoints are protected by \`X-Cron-Secret\` header (set \`CRON_SECRET\` in Forgejo repo secrets + production env).
## Schema changes (migration 0118)
Two new nullable columns on \`sports_seasons\`:
- \`standings_last_changed_at\` — written by \`syncStandings()\` when data actually changes
- \`last_simulated_at\` — written by the cron job after a successful simulation run
## Deployment notes
1. Add \`CRON_SECRET\` to Forgejo repo secrets (generate with \`openssl rand -hex 32\`)
2. Add same value to production environment
3. Migration runs automatically via the \`migrate\` container on deploy
## Test plan
- [ ] \`curl -X POST https://brackt.com/admin/jobs/run-daily-snapshots -H "X-Cron-Secret: ..."\` → 200 \`{total, succeeded, errors}\`

three places that re-anchor timeRemaining to the client clock, replacing
duplicated Date.now() + timeRemaining * 1000 expressions
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
## Summary
- The countdown display used `data.expiresAt` (server-side Unix timestamp) subtracted from `client Date.now()`. When the server clock runs ~2-3s ahead of the client (observed in production), the display was inflated by that delta.
- Fixes three linked symptoms: timer starting at 2:02 instead of 2:00, chess-clock increment crediting 1:54 instead of 1:55, and the commissioner's adjust-time-bank dialog disagreeing with the visible countdown.
- Fix: replace all server `expiresAt` timestamps with a client-local expiry from the server-provided `timeRemaining` integer (`Date.now() + timeRemaining * 1000`). The skew then cancels algebraically when the server computes credit.
## Sites changed
- `handleTimerPickStarted` — fires after every pick (the main fix)
- `handleDraftStateSync` — reconnect path
- `useState` initializer in the draft room — initial page load seed from loader data (uses `loaderTimerNow` server timestamp to compute remaining server-side, then re-anchors to client clock)
## Test plan
- [ ] Start a chess-clock draft (2:00 bank, 15s increment) — timer should show exactly **2:00** when a team goes on the clock
- [ ] Pick at 1:40 — new bank should show **1:55** (100 + 15s)
- [ ] Commissioner adjust-time-bank dialog — displayed remaining should match the countdown
- [ ] Force autopick at any displayed time T — new bank should be T + increment
- [ ] Reconnect mid-pick — timer should resume at the correct remaining time

## Summary
- **Timer bank broadcasts**: emit `timer-bank-updated` after every pick so all clients immediately see the updated bank instead of waiting for the next `timer-pick-started`
- **Increment accuracy**: capture `pickMadeAt` at route entry (before auth/DB overhead) and use `Math.ceil` so credited seconds always match the client countdown display
- **Race condition fix**: hold `schedulingInProgress` lock for the full timer callback to prevent the recovery interval from scheduling a duplicate timeout mid-pick
- **force-autopick fix**: call `rescheduleTimer` so the next team's clock starts immediately instead of waiting for the old timeout to naturally expire
- **adjust-time-bank fix**: for on-clock teams, shift `picksExpiresAt` by the adjustment and reschedule so the client countdown updates; block adjustments that would reduce the bank to zero
- **New socket events**: `timer-pick-started`, `timer-overnight-paused`, `timer-bank-updated` with full type definitions; removed dead `timer-update` event
- **Reconnect sync**: `draft-state-sync` now includes `expiresAt` for the active timer and `isOvernightPause` state so reconnecting clients see accurate countdown and pause banner immediately without a page reload
- **Room closure countdown**: capture client-side timestamp when draft completes so the "Room closes in X" countdown actually ticks down before the loader revalidates with `draftCompletedAt`
- **Countdown interval**: run at 500ms with `Math.ceil` to prevent skipped seconds under event loop pressure
- **Overnight pause UX**: `canPick` only blocks on commissioner pause — overnight pause freezes the timer but the on-clock player can still pick early
- **Overnight pause refactor**: extract `checkOvernightPause` to `server/overnight-pause-check.ts`, breaking the `timer↔socket` circular import and sharing the timezone cache across both callers with correct eviction
- **PostgreSQL type fix**: cast `varchar` owner ID to `uuid` in `getTeamTimezone` join
## Test plan
- [ ] Manual pick: all clients see bank increment immediately after pick
- [ ] Timeout pick: all clients see bank update (0 → increment); next clock starts within ~1s
- [ ] Force-autopick: next team's clock starts immediately; no "Pick already made" log
- [ ] Force-manual-pick: all clients see bank increment
- [ ] Pause while clock running: countdown freezes on all clients
- [ ] Resume: clock continues from frozen value
- [ ] adjust-time-bank on on-clock team: countdown shifts immediately
- [ ] adjust-time-bank to zero: returns 400 error
- [ ] Reconnect (socket disconnect/connect): countdown resumes for correct team
- [ ] Hard refresh mid-draft: on-clock indicator and countdown correct immediately
- [ ] Draft complete: "Room closes in X" counts down
- [ ] Overnight pause: banner shows, pick buttons still enabled, timer frozen
- [ ] `npm run test:run` — all 158 files / 2351 tests pass

## Summary
- **MLB simulator seeding now responds to projected wins**: replaced hardcoded FanGraphs `p_div`/`p_wc` probability draws with Binomial regular-season simulation. Admin-entered projected wins (via Elo) now drive both playoff _qualification_ odds and in-bracket game win probability, not just the latter.
- **Reads current standings mid-season**: `getRegularSeasonStandings` is called so synced `wins`/`gamesPlayed` feed into each simulation iteration's projected final standings.
- **27× seeding performance improvement**: `sampleBinomial` now uses a Box-Muller normal approximation for `n ≥ 30`, dropping the seeding phase from ~243M to ~3M `Math.random()` calls per 50K-sim run (pre-season, 162 remaining games × 30 teams).
- **Missing-standings warning**: when standings exist for some teams but not all recognized ones (partial sync), a `logger.warn` now surfaces which teams are falling back to 0 wins / 162 remaining instead of silently distorting seeding.
- **Cleanup**: `eloToRDif` calls `rawWinRateFromElo` instead of inlining the same formula.
- **Simulate errors surface inline**: moved simulation action from dedicated route to parent page `intent="simulate"` so errors display inline rather than crashing to an error page.
## Test plan
- [ ] `npm run test:run -- mlb-simulator` — 49 tests pass
- [ ] `npm run typecheck` — clean
- [ ] Trigger a simulation from the admin panel for an MLB season with projected wins entered; confirm teams with higher projected wins show meaningfully higher EVs
- [ ] Confirm that running simulate with no projected wins entered (pre-season defaults) still produces a valid bracket
- [ ] Check logs after simulating a season where some teams lack standings rows — confirm warning appears

## Problem
Running a simulation on MLB (and any sport where the readiness check fails) showed a confusing React Router 400 error instead of the real failure reason. The cause: the simulate route had only an \`action\` export. When the action **threw** instead of redirecting, React Router tried to render the route via GET to display the error — hit the missing loader — and replaced the real error with its own internal 400.
A secondary issue: the interim fix used \`?simulationError=\` query params, which had three problems identified in code review:
- Stale errors re-appeared when pressing browser Back after fixing the issue
- The param reflected arbitrary text into the UI (social engineering surface)
- The styling didn't match the established \`bg-destructive/15\` error pattern
## Changes
**\`admin.sports-seasons.\$id.simulate.tsx\`** — strip the action; keep a loader-only redirect stub so bookmarked URLs degrade gracefully to the season page.
**\`admin.sports-seasons.\$id.tsx\`** — add \`intent="simulate"\` to the action dispatcher (matching \`delete\`, \`rescore\`, \`sync-standings\`, \`finalize-standings\`). On success: redirect to expected-values (unchanged). On failure: return \`{ simulateError: message }\` displayed inline with the correct \`bg-destructive/15\` styling.
## Test plan
- [ ] Click Run Simulation on a season with a missing readiness input → error message appears inline below the description text, styled consistently with other errors on the page
- [ ] Click Run Simulation on a fully-configured season → redirects to expected-values as before
- [ ] Navigate directly to \`/admin/sports-seasons/<id>/simulate\` in browser → redirects to season page (no 400)
- [ ] Run simulation, see error, fix the issue, run again successfully → no stale error message persists

- **Refactor**: Extracted a shared `espn.ts` utility module, eliminating 4× duplication of `statsMap()`, `flattenEspnStandings()`, ESPN interfaces, and the `playoffSeed` → conference rank logic across adapters.
- **Bug fixes** found during review and applied across all affected adapters:
- `parseConferenceRank`: `|| undefined` falsy-zero bug replaced with `isNaN` guard
- Sort comparators: stable alphabetical tiebreaker added to MLB, NBA, WNBA
- `winPct`: falls back to `wins/(wins+losses)` if ESPN omits the stat (was silently 0)
- statsMap pre-built once per entry before sorting in all adapters (was rebuilt per comparison)
- WNBA `parseEntry`: accepts pre-computed `sm` instead of rebuilding it internally
- MLB `gamesBack`: tests updated to reflect ESPN returns numeric `0` for division leaders (old API used `"-"` → `undefined`)
## Test plan
- [ ] All 60 standings-sync unit tests pass (`npm run test:run -- app/services/standings-sync`)
- [ ] Trigger MLB standings sync from admin panel and confirm it returns data without a 406

## Summary
- **Dockerfile layer caching**: `development-dependencies-env` now copies only `package.json`/`package-lock.json` before `npm ci` (was `COPY . /app`), so the npm install layer is cached on every code-only commit instead of rebuilt from scratch
- **Skip QEMU**: `platforms: linux/amd64` added to `build-push-action`, cutting `setup-buildx-action` from ~5 min to ~30 sec
- **npm cache in CI jobs**: Manual `actions/cache@v3` blocks (copy-pasted 3×) replaced with `actions/setup-node@v4` + `cache: 'npm'`, which handles path/key/restore automatically and pins Node 20 explicitly
- **Harden `.npmrc`**: Switched from `COPY .npmrc` to `--mount=type=secret,id=npmrc` in both `npm ci` stages — the file is available during install but never written into a Docker layer, so it cannot leak through the registry build cache regardless of future contents
## Expected timing
| Step | Before | After (code change) |
|---|---|---|
| Setup buildx | ~5 min | ~30 sec |
| Build + push | ~5 min | ~1-2 min |
| Deploy (docker pull) | ~5 min | ~1-2 min |
| **Total** | **~15 min** | **~3-5 min** |
## Test plan
- [ ] Push a code-only commit to main — confirm `setup-buildx-action` logs ~30s (no QEMU), Docker build shows `CACHED` for npm install layers, build+push completes in ~1-2 min
- [ ] Check deploy job — `docker compose pull` should show most layers as `Already exists`
- [ ] Push a commit that changes `package.json` — confirm npm layer correctly re-runs (not cached)
- [ ] Confirm deployed app is functional
