- LineupPitch: both XIs on a vertical pitch at FotMob's per-player
formation coordinates — shirt numbers, live ratings, goal badges,
formation + coach labels. Substitutes take over the outgoing player's
slot (paired through ESPN's 'X replaces Y' commentary with a unique
same-minute fallback — the sources romanize names differently), with
a subbed-off strip below; the page's live refetch keeps it current
through the match. Falls back to the list view (and hides predicted
pre-kickoff XIs) when no confirmed lineup is captured.
- /api/match-rich now serves the trimmed FotMob lineup (only complete,
fully-positioned XIs)
- Fix: vs-Market label box was too narrow — the probability bar covered
the end of 'DraftKings'
- Timeline spine no longer runs past the kick-off/full-time pills

GET /api/match-rich/:num projects the captured provider data for the
match center: every shot with pitch coords and xG oriented to
home/away (FotMob payloads now carry team ids, v2 + settle-versioned
refetch), team xG sums, the momentum curve, player of the match with
rating, FIFA's official attendance/stadium/referee, and kickoff-hour
weather. Verified on real data: South Korea 2.31-0.83 Czechia on 22
oriented shots, POTM Hwang 8.9, referee Amin Mohamed Omar.

The first heal attempt missed both matches: a 02:00 UTC kickoff files
under the PREVIOUS day in ESPN's ?dates= param (ET-based), and the
backfill skipped today's UTC date entirely. Now any started-but-
forgotten fixture triggers fetches for its UTC date and the day
before, covering the ET offset in both directions.

The persistence table shipped empty just as ESPN's default scoreboard
window rolled past matchday 1 — prod forgot both results. Rather than
patching the DB by hand, boot now re-fetches the date-scoped
scoreboard for any past day whose fixtures still look scheduled and
merges + persists the results. Heals fresh databases and any future
data loss the same way.

Four new feeds, all verified against real tournament matches:
- FotMob (unofficial, works from the VPS again): per-shot xG/xGOT with
pitch coords, team xG, player ratings, POTM, momentum, attacking
zones — trimmed payloads (~87KB/match) on a gentle 90s-live/30m-idle
cadence. Capture-first: this source could lock again any day.
- FIFA official v3: confirmed lineups with player IDs, typed XY event
timelines (80 events for the opener), attendance + named referees,
tactics — id-mapped via the calendar, hot while live.
- Open-Meteo: kickoff-hour weather per venue from a build-time geocoded
venues.json (with elevation — Azteca 2,240m); fetched in the enrich
loop inside the 48h horizon.
- DraftKings scorer props (first/last/anytime goalscorer per athlete)
via ESPN's core propBets, insert-if-changed line history, athlete
names resolved through a 30-day cache.
Also fixes a real resilience gap found along the way: fixture results
now persist in SQLite and restore at boot — previously a restart after
ESPN's scoreboard window moved on would silently forget a match day
(standings, model and scoreboard would all regress).

A restart during a live match sat behind the multi-minute odds sweep
before the first scoreboard poll. The live loop now starts immediately
after fixture mapping; odds/backfill/enrich follow on their own
rate-limit keys.

The boot refit fires before live state is restored, so restarts lost
this tournament's matches from the fit until the nightly timer. A
one-shot follow-up at +5 minutes closes the gap.

Fully progressive: without VAPID keys in the environment the API says
404, the bell never renders, and the service worker addition (a push
handler via workbox importScripts — no SW strategy change) is inert.
With keys: a bell on each team page requests permission, subscribes
(one team per device) and the server diffs fixture states on every
broadcast to push Kickoff / Goal / Full time to that team's followers.
Dead endpoints (404/410) self-clean. Round-trip verified locally with
dev VAPID keys; disabled mode verified too.

ESPN's keyEvents carry participants[].athlete for goals — no text
parsing needed. The normalizer now extracts scorer/scoring/shootout
(payload versioned, with a boot backfill that re-stores summaries
saved by the old normalizer), /api/goldenboot aggregates per-player
goals (own goals and shootout kicks excluded), and the Teams page
leads with the top-10 race. Verified against tonight's real goals.

Crawler-visible <title> + og:title/description are injected into the
SPA shell server-side: match links carry the score or the model's
probability split, team links the current title odds — honest framing
included. Plain shell for every other route.

While a match runs, every poll records the in-play model probability
per game state (insert-if-new on minute+score) into inplay_history.
The match page draws it as a stacked area chart — home fills from the
bottom, away from the top, the gap is the draw — with minute ticks and
a 50% guide. Shows live (under the win-probability bar) and after full
time as its own card. EN/DE strings included.

The first prod snapshot landed as a 0-byte file with a stale journal:
SQLite needs byte-range locking on the VACUUM INTO destination, which
the CIFS storage box refuses. Now: vacuum into a local temp file, then
a plain sequential copy to the archive (always CIFS-safe), cleaning up
the temp and any leftover journal.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The 'external drive' turned out to be a CIFS-mounted Hetzner storage
box — SQLite cannot run on a network mount (WAL shared memory and
locking break), and the live DB is only ~7MB anyway. So: the hot
database stays on the local volume, and a nightly VACUUM INTO snapshot
(transactionally consistent, a plain sequential file write — perfect
for CIFS) lands in /data/archive, which compose binds to the storage
box via HOST_ARCHIVE_DIR. 14-day retention, plus a snapshot at boot.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
HOST_DATA_DIR in .env can now point /data at a host path (the 1TB
external drive) instead of the named volume, so odds history, caches
and snapshots stop eating the 128GB root disk. A daily prune drops
cache entries stale for over a week and ingest-log rows older than 14
days — faster polling no longer means unbounded DB growth.

Validated on the strict 2018-2022 window and confirmed on the untouched
2022-2026 test set (RPS 0.1703 vs 0.1721 over 4,448 matches):
- the Elo member now blends 30% of a 3x-faster Elo walk, so recent
results move ratings much harder
- ensemble weight shifts from 75/25 toward Elo to 45/55 toward the
time-decayed Team-DC member — the recent-form model now leads
- Team-DC refits nightly (and at boot) on the 15-year window plus every
finished 2026 match, via a new committed-at-build dcTrain.json
(server-only, excluded from the PWA precache)
- a recent-form goal multiplier was also tested and did NOT validate;
it ships disabled, and backtest.json records the whole decision
buildBacktest.ts grew the experiment harness: wider xi/k grids, the
fast-Elo and form variants, a pre-registered ship bar (>=0.0005
validation RPS), and a 7-day refit-cadence check. Older ratings.json
files still work — all new model fields are optional with golden
regression coverage.

The live staleness bug: liveTick refetched ESPN summaries every 20s but
the cache TTL was 5 minutes, so in-play stats/timeline barely moved.
Summaries now take a live flag (15s TTL in play), the scoreboard TTL
drops 20s->5s, and polling gets three tiers (8s in-play / 20s near
kickoff / 10m idle) via a pure, tested cadence module. The
football-data fallback is throttled to one attempt per 15s so the 8s
cadence can never breach its 10 req/min cap. Enrichment runs every 5m
(was 20m); client refetch intervals tighten to 10s (live match page)
and 30s (scoreboard).

- scripts/processStatsbomb.ts: one pass over the 17GB StatsBomb lake (4,235
matches) -> lakestats.json (12.82GB events / 14.9M events / 6,919 players),
scorestate.json (goal-rate multipliers by game state — shipped as an insight,
NOT wired into in-play: the raw effect is selection-biased toward stronger
teams and would distort a calibrated model), fingerprints.json (40/48 nations'
shots/xG/set-piece share from real event data). Artifacts committed; raw lake
stays local (gitignored).
- /data page + /api/data/stats: the gigabytes made visible — lake counters,
historical archive, live-collection counts (odds lines, frozen forecasts,
enrichment), per-source health with freshness. Footer links.
- Term component: plain-language glossary tooltips (RPS, Brier, ECE, Elo, xG,
de-vig, ensemble) attached where metrics appear.

- prediction_snapshots: model + de-vigged market frozen ≤15min pre-kickoff
(or at first sight of a live match, flagged 'late' and excluded from totals).
- src/lib/model/scoring.ts: ONE shared RPS/Brier/log-loss implementation for
the backtest and the live scoreboard.
- /api/scoreboard + /scoreboard page: per-match model-vs-bookmaker bars, RPS
for both after FT, 'closer' badges, running head-to-head with honest rules
printed (small-sample caveat included). Nav: 'vs Market'.
- Methodology page now shows the three-way split + ensemble bake-off variants.
- Verified end-to-end with a simulated match: snapshot froze model 80.7% and
DraftKings 67.0% (de-vig correct), both scored at FT, late-flag honored.

- src/lib/model/teamDc.ts: per-team attack/defence Dixon-Coles via weighted MLE
(Maher iterations), exponential time-decay, shrinkage for thin histories,
learned home multiplier; log-pool of score matrices. 7 vitest cases.
- buildBacktest.ts rewritten as a strict three-way-split bake-off: params
pre-2018, tune (xi, k, w) on 2018-2022 validation, final scores on untouched
2022-2026 test (4,448 matches). Result: ensemble RPS 0.1721 beats Elo-DC
0.1726 and Team-DC 0.1801; ECE stays 0.01. Tuned: xi=0.5 k=5 w=0.75.
- Runtime now IS the backtested model: ratings.json carries teamDc+ensembleW;
matchMatrix() pools both members for predictions, Monte Carlo and advance
probs; ModelEngine re-rating preserves ensemble params; lambdas reported as
matrix expectations (drives in-play).
- scripts/buildSquadValues.ts: Transfermarkt FIWC participants page -> all 48
squad market values (France 1.52bn ... Qatar 20m). Display/availability layer
only — June-2026 values are NOT in the backtested model (would leak).

- docs/V3-GIGA-PLAN.md: the v3 plan (data lake to 7+GB, GIGA ensemble, scoreboard,
UI clarity) with the honest reframe: perfect accuracy = perfect calibration;
'beat the betting sites' = a live public head-to-head, scored with proper rules.
- src/lib/odds.ts: American-ml → decimal, de-vig (normalize away the margin),
overround; 3 vitest cases incl. tonight's real opening lines.
- ESPN core odds adapter (server/src/ingest/espnOdds.ts): captures DraftKings
1X2 moneylines + O/U + spread per fixture; follows $ref pointer items.
- odds_history table (insert-if-changed → clean line-movement history);
scheduler odds sweep every 3h over a 14-day horizon, first sweep at boot;
/api/odds + /api/odds/:num. Odds are a benchmark ONLY — never a model input.
- Boot speed-up: fixture↔event mapping skips dates already fully mapped.
- Verified: 54 fixtures captured with real moneylines locally.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
- src/lib/model/inplay.ts: in-play win probability — remaining goals modelled as
time-scaled Poisson processes convolved with the current score; recomputed each
tick. 4 vitest cases (locks at FT, lead grows decisive over time, sums to 1).
- ESPN summary normalizer extended with the live event timeline (keyEvents);
preview now carries liveStats + events. Scheduler refreshes LIVE matches'
summaries every live tick (~20s) for fresh stats/timeline.
- /match/:num is now a live match center: when live it shows in-play win
probability (driven by the WS score/clock), match stats bars and an event
timeline, polling while live; preview content for scheduled games, recap when
finished. Verified with a simulated live state (94% live vs 81% pre-match).

- Persistence via Node's built-in node:sqlite (zero native deps) on a Docker
volume: response cache, source health, fixture↔provider id map, per-fixture
enrichment, ingest log. Runtime bumped to node:24-slim + --experimental-sqlite.
- Resilient fetcher: DB cache + per-source rate-limit + jittered backoff +
circuit-breaker (blocked sources trip + skip; UI reads DB, never breaks).
- ESPN hidden API as the PRIMARY rich source (works from the VPS where SofaScore
403s): scoreboard (live scores w/ clock) + summary (venue, H2H, recent form,
lineups, team stats). football-data / SofaScore are fallbacks.
- Scheduler: maps all 72 group fixtures to ESPN event ids, polls live on a
dynamic cadence, enriches imminent fixtures into match_ext. /api/sources/health.
- Verified: DB populates (real H2H + form for opening matches), 22 tests pass,
Docker image runs node:sqlite on the volume and persists across restart.
