* Fix NHL bracket-aware simulation and MLB sourceElo support
NHL: NHLSimulator now checks for a populated playoff_game bracket before
falling back to season-projection mode. When a bracket exists (e.g. via
simple_16 template), it simulates the actual bracket structure, respecting
completed matches and using ELO+odds blending for the rest — matching the
pattern used by Snooker, NBA, and UCL simulators.
MLB: MLBSimulator now reads sourceElo from participantExpectedValues and
converts it to an effective RDif (via eloToRDif), overriding the hardcoded
TEAMS_DATA.rdif when present. This wires up the expected-wins admin form
(which saves sourceElo) to the simulation engine.

* Wire sourceElo from projected wins form into NBA, NHL, and WNBA simulators
All three simulators had entries in simulator-config.ts (enabling the projected
wins form in the admin UI) but silently ignored the sourceElo that was saved.
NBA: Both bracket-aware and season-projection modes now load sourceElo and
prefer it over hardcoded TEAMS_DATA elo. Added resolvedElo field to TeamEntry
so eloOfEntry() uses the correct value throughout.
NHL: Season-projection mode now fetches sourceElo + sourceOdds in a single
parallel query (removing the duplicate evRows query). Bracket-aware mode also
loads sourceElo alongside sourceOdds. Both modes use sourceElo > TEAMS_DATA > 1400.
WNBA: resolveElo() now accepts sourceElo as an optional highest-priority
argument. The evRows query fetches sourceElo alongside sourceOdds and passes
it through when building team entries.

* Add review fixes: NHL R1 validation, WNBA sourceElo tests, NHL bracket unit tests
- NHLSimulator.simulateBracket: remove unused nameById variable
- NHLSimulator.simulateBracket: validate all R1 participants before entering
Monte Carlo loop; throws with a clear message if any slot is missing
- wnba-simulator.test.ts: add 5 tests covering the sourceElo override parameter
on resolveElo() (overrides SRS, overrides futures, overrides fallback,
null/undefined fall through to normal priority chain)
- nhl-simulator.test.ts: add full bracket-aware integration suite (10 tests)
covering fallback to season-projection, structure validation errors, probability
distributions, fully-decided champion, and source tag

* Fix TS error: add resolvedElo to makeEntry in nhl-simulator.test.ts
TeamEntry requires resolvedElo after the simulator refactor.

* Fix lint: replace non-null assertions with null-safe alternatives in NHL test

* Fix NHL simulator dynamic seeding and code quality issues
- Replace hardcoded seeding probabilities with standings-based Monte Carlo
projection: simulates remaining regular season games per team using Elo
win probability vs. a league-average opponent, so mathematically eliminated
teams naturally fall out of playoff contention
- Fix double-simulation bug in wildcard pool: all 16 conference teams are now
projected exactly once via sortProjected([...divA, ...divB].map(projectTeam)),
then filtered — wildcard pool no longer re-runs simulateProjectedPoints with
fresh randomness independent of the division seeding
- Move ProjectedTeam interface, projectTeam(), and sortProjected() to module
scope (defined once, not recreated on every buildConferenceBracket call)
- Replace conference-level participant count check (east < 8 || west < 8) with
per-division checks (each division < 3) for a more actionable error message
- Add logger.warn when standings.length === 0 so admins know the sim is running
without synced data
- Remove unused easternTeams/westernTeams variables
- Simplify test: replace Object.fromEntries pattern with a plain for..of loop

* Fix oxlint errors in NHL simulator and tests
- Replace non-null assertions (data!) with optional chaining (data?.x ?? "")
- Move makeEntry helper to module scope to avoid recreating on every call

- Add 70/30 Elo + Vegas futures blending for per-game win probability,
mirroring the UCL simulator pattern; falls back to Elo-only when no
sourceOdds are stored in participantExpectedValues
- Adjust PARITY_FACTOR to better match Vegas championship implied
probabilities (COL was ~12% vs ~20% market expectation)
- Add 15 unit tests covering name normalization, team data lookup,
parity-factor math, seeding probability sanity, and eliminated-team checks

- Add app/lib/logger.ts: dev passes through to console; prod routes errors
to Sentry.captureException and warnings to Sentry.captureMessage, with
extra context preserved. Uses captureMessage (not captureException) for
string-only args to avoid fabricated stack traces.
- Add server/logger.ts: dev passes through; prod silences log/info but
keeps warn/error on stderr (Sentry not initialized in that process).
- Replace all console.* calls across 44 app files and 4 server files.
- Upgrade no-console from warn → error in oxlint; exempt logger files and
scripts/** via overrides.
- Add typescript/no-inferrable-types rule; fix violations in services and
simulators. Exempt test files (intentional string widening for switch/if
tests would break under literal type inference).

* Fix no-shadow and consistent-function-scoping lint violations
Resolves all 11 no-shadow and 16 consistent-function-scoping oxlint
warnings and promotes both rules to errors in .oxlintrc.json.
no-shadow: renamed Drizzle callback params (sports→s, matches→m,
seasons→s) to avoid shadowing outer imports; removed shadowed
destructures (eq, inArray) from where callbacks; renamed inner
template→bracketTemplate, prev→currentTimers, season→ss, name→teamName
(with name: teamName fix to preserve semantics).
consistent-function-scoping: moved formatDate, getRankBadge,
getMovementIndicator, getPositionBadge, getStatusBadge, toDateStr,
elo (×2), weightedPick, sortByMatchNumber (×2) to module scope;
moved formatTime (×2), isValidLeagueName, getDraftTimes,
makeSeasonQueues to file scope in test files.

* Fix no-non-null-assertion lint violations and promote to error
Eliminates all 208 no-non-null-assertion warnings across 38 files.
Promotes typescript/no-non-null-assertion from warn to error in
.oxlintrc.json.
Fix patterns applied:
- Map.get(key)! after .has() check → extract with get() + null guard
- Map.get(key)! on pre-populated count maps → ?? 0 default
- .set(id, map.get(id)! + 1) increment → ?? 0 before adding
- participant1Id!/participant2Id! on DB matches → ?? "" fallback
- array.find()! in tests → guard + throw or expect().toBeDefined()
- bracketTemplateCache.get(id)! → null guard extract
- Various nullable field accesses → optional chain or ?? default

* Fix prefer-add-event-listener, no-unassigned-import, require-module-specifiers
Resolves all 9 remaining non-console lint warnings and promotes all
three rules to errors in .oxlintrc.json.
- prefer-add-event-listener: converted onchange/onclick/onload
assignments to addEventListener in useDraftNotifications.ts and
admin.data-sync.tsx; stored changeHandler ref for proper cleanup
with removeEventListener
- no-unassigned-import: configured rule with allow list for legitimate
side-effect imports (*.css, @testing-library/jest-dom,
@testing-library/cypress/add-commands)
- require-module-specifiers: removed redundant `export {}` from
cypress/support/e2e.ts (file already has an import)

* Fix TypeScript errors from no-non-null-assertion fixes
Two fixes introduced by the non-null assertion cleanup produced type
errors:
- scoring-event.ts: `?? ""` was wrong type for a participant object map;
restructured to explicit null guards so TypeScript can narrow correctly
- standings-sync/index.ts: `?? null` after name-match lookup lost the
truthy guarantee, causing TS18047 on the write-back block; added
`participant &&` guard before accessing its properties

* Add npm run typecheck as Stop hook in Claude settings
Runs a full project typecheck at the end of each Claude turn so type
errors surface as feedback before the next message.

Closes#115
- Add `NHLSimulator` using NHL's divisional bracket format (top 3 per
division + 2 wildcards per conference, best-of-7 series, parity
factor 800). Elo ratings and seeding probabilities sourced from
elo.harvitronix.com/nhl/2025-2026 as of March 18, 2026.
- Add `nhl_bracket` to `simulatorTypeEnum` with migration.
- Register `NHLSimulator` in the simulator registry.
- Fix simulator type dropdown in admin to auto-generate from the
registry instead of a hardcoded list, so new simulators appear
automatically without a separate UI change.
Code review fixes applied to the simulator:
- Narrow `weightedPick` key type to the five seeding probability fields
(was `keyof NhlTeamData`, allowing `"elo"` which would silently
corrupt results)
- Remove uniform-random fallback in `weightedPick` — zero-weight draws
now return `undefined` and are skipped, preventing eliminated teams
from becoming wildcards
- Exclude unrecognized participants entirely (with a console warning)
instead of silently routing them into the Eastern wildcard pool
- Replace the confusing for-of loop over both conferences (with unused
`champ` variable and `!`-suppressed unitialized vars) with two
explicit sequential East/West blocks
- Track `effectiveN` for skipped degenerate draws so probability
denominators stay accurate; throw if all iterations are skipped
