Introduced a high-performance two-phase pipeline for league roster syncing via the League Dossier modal (Sync All Players) and Admin Console (Sync League). Phase 1 (~5–8s) synchronizes only active league night matches and records within 48 hours, immediately hot-reloading standings, schedules, and throw lore in place. Phase 2 continues in the background with an unobtrusive progress stepper to asynchronously backfill remaining career match sheets without locking the user interface.

Added full multi-column client-side sorting across the administrative player registry. Columns for Player ID, Name, Collins Rating, Stored Matches, Last Synced, and Sync Cooldown now support two-way ascending and descending sorting with ARIA-compliant sort state indications.

Elevated SQLite write serialization to a shared database-level async mutex, preventing lock contention across concurrent background syncs. Enforced admin authentication on hard cache purges (full_refresh=true), sealed task-cancellation permit leaks in outbound rate limiters, eliminated startup migration table scans, and added a dedicated database-verified /healthz readiness endpoint.

Fixed the Last Synced (UTC) column in the admin players registry table to display each thrower's authentic match sheet synchronization timestamp (last_synced_at) rather than falling back to bulk directory upsert timestamps (updated_at). Players who have not yet had individual match sheets synchronized now clearly display a formatted Never status.

Eliminated muddy reddish-brown backgrounds across the Trophy Case modal. Champion (1st), Finalist (2nd), and Podium (3rd) summary boxes and historical seasonal finish cards now all share the identical cool dark slate container styling as 2nd place (bg-slate-900/60 border-slate-800). Finishes are distinguished cleanly via gold (#eab308), silver (#cbd5e1), and bronze (#f59e0b) typographic highlights without jarring high-contrast card background clashes.

Audited and refreshed cards, pills, and alert banners across the site to replace opaque brown slabs with clean dark slate containers and glowing translucent accents. Updated offline notice banners, upstream outage alerts, upcoming match make-up badges, toss-up indicators, tactical trait badge fallbacks, and the profile banner Lane Scout drawer trigger. True red is strictly reserved for actionable attention states such as losses, negative rating shifts, and system errors.

Merged the upper Throw Rhythm Sequence Diagnostics card and the lower Score Distribution Table into a single authoritative Throw Progression & Score Distribution card. In Lane Mode, throwers see high-signal diagnostics and responsive micro-bar progression cards (T1 → T5). In Pro Mode, an integrated view switcher allows seamless toggling between visual cards and the comprehensive 7/5/3/1/0 tabular breakdown. Sudden Death overtime records and milestone rounds (Natural 25s, Supernatural 27s, 75 Club, 81 Club) are integrated directly beneath the active data view.

Relocated the Opponent Scoring Tier Performance chart from its previous cramped split-column layout beside the duplicate score table into a clean, dedicated full-width card in Pro Mode. Provides Chart.js with substantial horizontal canvas width to clearly plot win rates and scoring averages across Elite (≥68), Competitive (62–67.9), Mid-Tier (55–61.9), and Developing (<55) tiers.

Established Lane Mode as the default view mode across the platform for immediate, low-clutter venue scouting. Progression cards have been compacted with 5px slim micro-bars and a 2-column mobile wrap to completely eliminate horizontal container clipping on mobile screens, with user view preference seamlessly preserved in localStorage.

Promoted Upcoming Matches to the 2nd tab immediately following Overview in both the navigation bar and view hierarchy (Overview & Intelligence → Upcoming Matches → Seasons & Tournaments → Opponent Matrix & Scouting → Circuit & Majors), providing immediate access to upcoming scheduled matchdays and pre-match opponent intelligence.

Eliminated stacked duplicate trait strips: in Lane Mode, the banner badge strip is hidden so the inline Lane Scout dossier holds single authoritative prominence, while Pro Mode retains the compact summary and drawer trigger. Furthermore, unplayed disciplines (0 matches, such as Big Axe or Knives for Standard-only throwers) are automatically hidden in Lane Mode so active disciplines expand cleanly, and dimmed with subtle opacity in Pro Mode.

Standardized on Rubber Deciders (R3) across profile KPIs, Lane Scout cards, and modal dialogs, unifying previously split naming. Renamed situational clutch to Situational Clutch Performance, updated trailing metrics to When Trailing Entering T5 to avoid collision with margin-of-victory modeling, added When Tied Entering T5 to complete the symmetric Leading / Tied / Trailing tri-state breakdown, and added a direct View Complete Opponent Matrix → bridge to the H2H tab.

Integrated pytest-playwright with 8 comprehensive end-to-end headless Chromium tests verifying landing page interactivity, default Lane Mode styling, Pro mode toggling, DOM hydration, mobile viewport adaptation without clipping, modal keyboard escape dismissal, consolidated throw card view switching, and cross-tab navigation.

Implemented a two-tier synchronization pipeline that prioritizes active and recent season matches (within 90 days or current season) in Tier 1 so thrower profiles and active metrics render in 2–3 seconds. Historical career seasons (hundreds of matches) seamlessly backfill asynchronously in Tier 2 with real-time progress updates, rating timeline reconstruction, and intermediate dashboard refreshes.

Engineered an in-memory summary cache inside AnalyticsEngine with thread-safe lock management, deep-copy response isolation, and sub-millisecond query returns. Filter switches (Standard, Premier, Big Axe, timeframes) and repeated profile visits no longer trigger expensive multi-table joins. Caches automatically invalidate upon background sync milestones, Tier 1 completions, or administrative record deletions.

Added full Progressive Web App (PWA) support with a Web App Manifest (manifest.json) and root-scoped Service Worker (/sw.js). Features stale-while-revalidate API caching for thrower summaries and cache-first delivery for CSS, JS, and vendor dependencies, guaranteeing full functionality and opponent scouting access inside axe venues with poor or dead cellular reception. Added automated offline/online status alerts.

Standardized top headers across all pages with unified branding, the "Not affiliated with IATF" companion badge, and complete reciprocal navigation links across all views (Insights, Changelog, About & Policy, Support, and Dashboard). Decluttered the header by moving thrower search and discipline/time range filter pills out of the global header into a dedicated player controls toolbar on the active dashboard, eliminating redundant search inputs on the landing page. Aligned the Admin Console padding and container width to precisely match all other views.

Added full ArrowLeft, ArrowRight, Home, and End keyboard navigation to the dashboard tab list with synchronized aria-selected, tabindex, and URL hash routing. Converted unsemantic search dropdown items to accessible <button type="button" role="option"> elements, added role="group" with synchronized aria-pressed toggles across all filter groups, added scope="col" across data tables, and replaced misleading external link icons on internal thrower profile switches.

Unified the main column container width across all secondary views (Changelog, About & API Policy, Community Insights) to max-w-7xl, matching the main Dashboard layout for consistent usable screen real estate. Corrected league standings placeholder colspans to 7 columns, wrapped the rating history ledger in horizontal scroll containers, added bottom close dismissal buttons to the League Dossier modal, styled Premier league badges with distinct purple palette styling, and eliminated redundant hardcoded inline border colors.

Fixed an issue in _determine_needed_match_ids where fresh database initializations erroneously applied a 90-day recency cutoff to unrecorded historical matches, truncating veteran player records from hundreds of career matches down to recent matches. All unrecorded historical matches are now comprehensively ingested while continuing to preserve intelligent skip logic for old completed matches during subsequent delta syncs.

Eliminated cyclical polling and alert toggling during match synchronization. Scoped tier-readiness tracking, added silent in-memory dashboard updating for intermediate and completion milestones, and delegated sync progress exclusively to the dedicated live progress banner. Fixed CSS stacking contexts (z-index) on the player toolbar so the thrower autocomplete search dropdown cleanly overlays on top of profile cards and metrics without being clipped.

AxeProgress officially graduates from beta to v1.0.0 General Availability following comprehensive 5-dimensional security, logic, and operational hardening across all core services.

Hardened admin endpoints to fail closed with 503 Service Unavailable when unconfigured in production, removed external CDNs from Content Security Policy (CSP) for pure 'self' isolation, and added attribute-safe quote escaping (escapeJsAttr) across interactive opponent selection modals.

Fixed falsy rate fallbacks in the Monte Carlo simulation engine to accurately preserve legitimate 0.0% clutch and sudden death win rates, with built-in zero-sum defense for unplayed overtime match states.

Integrated an interactive Monte Carlo Forecast mode across league schedules, displaying projected win probabilities, score spreads, Tale of the Tape comparisons, and dynamic 🔥 Toss-Up and ⚡ Upset Alert indicators.

Completed matches in the forecast view now render side-by-side actual scorelines alongside the prediction model, clearly highlighting verified favorite wins (✓ Forecast Verified) or underdog upsets (⚡ Upset Occurred).

Introduced a 4-card overall accuracy KPI banner tracking overall forecast success rates, total verified matches, logged upsets, and pending matches, alongside per-week accuracy breakdown pills.

Calibrated the simulation engine with Bayesian sample shrinkage toward league baselines ($K = 60\text{ axes}$) and clutch regression ($K = 10\text{ calls}$), guarding against small-sample distortions in early-season matchups.

Corrected situational clutch calculations (When Leading, When Trailing / Comeback Pressure, and Level / Tied) to evaluate the pre-throw round score differential entering Throw 5 (r.player_score - t.score vs r.opponent_score - 5.0). Eliminates post-throw feedback distortion where hitting a clutch 7 previously flipped trailing comeback rounds into leading statistics.

Milestone badges for the 75 Club are now dynamically synthesized and enriched directly from the thrower's stored league seasons with averages $\ge 75.0$, bridging upstream registry synchronization gaps across modern Premier seasons.

Enabled FastAPI GZipMiddleware with a 1 KB threshold, providing automatic gzip compression across all JSON payloads, HTML templates, and static assets.

Established a dedicated community home page highlighting long-form endurance duels, official IATC skills competition standings, and historical scoring lore, keeping the About page focused purely on architecture, telemetry, and API stewardship.

Relocated the sudden death marathon leaderboard with explicit dataset visibility documentation detailing the coverage of regular season matches and 1-day tournaments versus aggregate-only Week 8 league playoffs.

Ingested official AxeScores competition results across all four core IATC skills disciplines: Ambidextrous (Ambi), Doubles, Time Trial, and Around The World.

Added dedicated clutch calling percentage and success metrics directly into the League Dossier standings table and the Active Season overview header cards (e.g. 50.0% (42/84) with detailed 7s breakdowns), providing granular insight into thrower clutch performance under competitive pressure.

Introduced a new fun statistics section on the About page tracking the longest sudden death overtime duels and Big Axe tiebreakers across all stored matches in the platform database. In addition, throwers now have their personal longest sudden death duel highlighted directly in their profile overview scouting card.

Added a historical podiums summary to the thrower's Trophy Case modal and accolades tray, computing 1st place championship titles, 2nd place finalist finishes, and 3rd place podium finishes entirely from cached player profile seasons without generating extra upstream network requests.

Refined the Collins Rating History ledger and match tables to display exact single-day tournament dates or event week labels without synthetic weekly date estimations.

Launched the Live Site Statistics & Telemetry dashboard on the About page, exposing local platform storage footprint (players, matches, throws, leagues, venues, milestones, circuit rankings, SQLite DB size), time-windowed API calls (24h/7d/30d), total wire bandwidth retrieved, 24h average roundtrip latency and pacing delay, and upstream success rate.

Added a granular telemetry table categorizing requests and wire bandwidth across all active synchronization categories: /match, /player, /ratings, /records, /club, /iatc, /tournament, and /league.

Created a dedicated public JSON endpoint GET /api/site-stats for live telemetry inspection without authentication. Cleaned up the Admin Console to remove redundant metrics and keep the interface focused strictly on player cache controls, force synchronization, and real-time request logging.

Launched the Tale of the Tape comparison modal, comparing 3s, 1s, drop percentages, aimed throw accuracy (Throws 1–4), clutch call frequencies, and situational clutch conversion across leading, trailing comeback pressure, and tied scenarios. Includes dynamic temporal chips (Active Year 2026, 90 Days, 60 Days, 30 Days), discipline selectors, and full unbounded direct encounter match history.

The Interactive Scouting Dossier search bar now indexes across both encountered past rivals and 27,000+ unencountered global directory throwers with automatic background match sheet caching and instant profile simulation.

Engineered a dedicated get_comparison_profile engine utilizing multi-threaded concurrent execution (ThreadPoolExecutor) to extract comparative profiles in parallel, cutting comparative query latency by over 55%.

Replaced keyword title heuristics with a physical date-span hierarchy. Events spanning ≤ 4 days (Ironman tournaments, Daddy's Daycare, Super Bowl Sunday, Farewell Marathons) are deterministically classified as tournaments, while leagues spanning ≥ 14 days are classified as multi-week regular seasons. Added match calendar clustering analysis for undated events.

Conducted an end-to-end performance sweep of the entire analytics engine. Eliminated nested 1.5M row scans in get_perfect_round_breakdown (dropping query latency from 220ms to 2.5ms, an 85x speedup), optimized sudden death tiebreaker round scans from 39ms down to 7ms, and replaced chunked N+1 database queries with fast indexed batch operations.

Engineered dedicated composite covering indexes across throws, rounds, and matches (idx_rounds_player_match_order, idx_throws_player_match_clutch, idx_throws_player_round_score) and consolidated situational clutch metrics into a unified single-pass SQL execution. Yields up to 71% profile loading latency reduction across heavy multi-thousand match profiles.

Added a full-featured Rating Ledger modal accessible directly via the rating progression header or by clicking any data point on the Chart.js line graph. Features instant opponent and league text search, multi-axis filtering (Wins/Losses, Rating Gains/Drops, High Stakes ≥10 pts), multi-criteria sorting, dynamic summary KPIs (Filtered Net Δ, Peak in View, Best Win Δ, Toughest Drop Δ), and smooth internal table scrolling.

Track official tournament rankings across all sanctioned divisions with active competitor counts and field percentiles (e.g. Top 3% of division). Includes bracket seed gap calculations (+X pts to overtake next rank) and Top 8 / Top 16 Regional Championship Playoff Cutoff indicators with cycle selector tabs (⚡ Active Cycle, 📁 2025-2026, 🌐 All Cycles).

Live qualification pathway tracker for the upcoming June 2027 IATC World Championship cycle. Identifies confirmed bids (Premier Top 8, Standard Top 4, Wilson Cup, 70+ Average) as well as bubble criteria diagnostics (seasons with member club / 3, 70+ season counters, best finishes).

Comparative high-stakes analytics contrasting elimination tournament performance against regular weekly league play across 4 core metrics: Match Win Rate, 3-Round Throw Score Average, Throw 5 Clutch Accuracy, and deciding Round 3 Rubber Win Rate with player pressure profiles (⚡ Tournament Riser, ⚠️ High-Stakes Shift, ⚖️ Steady Competitor).

Streamlined accolades tray with an interactive modal detailing IATC bids, 81/75 Club perfect games, and World Records. Added a direct contact modal with fast one-click copy for email, Telegram, and Signal.

Looking up any thrower now automatically refreshes their match history in the background if their cached data is more than 24 hours old or has never been synced before. Profile pages render instantly from local cache while updates download quietly. When the 1-hour cooldown expires, an inline [Sync Fresh Matches] action appears right on the cache status bar. Streamlined the profile header to give milestone badges (81 Club, World Records) and multi-discipline ratings plenty of breathing room.

Added first-class support for IATF Knives competitions. Features a dedicated Knives dynamic filter pill in the navbar, full throw accuracy aggregations, and an expanded 4-card Discipline Performance Matrix (Standard, Premier, Big Axe, Knives) on the overview tab.

Overhauled query indexing and analytics aggregation across career match histories. For players with over 2,000 matches (43,000+ individual throws), full profile loading and rating progression generation dropped from 6.4 seconds down to under 1 second (978ms).

Added an interactive toggle on the Collins Rating chart allowing throwers to switch between Collapsed mode (consecutive match sequence, collapsing off-season hiatuses) and Calendar mode (proportional time scale showing dates and season gaps).

Enforced unique opponent ID isolation to prevent stats merging for players with identical names. Added an unobtrusive Not affiliated with IATF disclaimer badge in headers linking to platform attribution and policies.

Added dedicated Full Reset actions across the Admin Dashboard table and direct player ID lookups alongside Delta Sync. Completely purges cached match records and re-downloads historical throw sheets fresh from AxeScores.

Added granular tracking for Natural 25s (5 pure bullseyes), Supernatural 27s (4 bullseyes + 1 clutch), Unnatural 25s (dropped regulation throws recovered via clutch), 75 Club matches, and 81 Club Premier perfect games with interactive tooltips.

Added a comprehensive scoring terminology guide on the About page and interactive tooltips on the League Dossier modal table explaining 81s vs 15s.

Standardized all 8 footer metric cards across the Opponent Scoring Tier and Throw-by-Throw Sudden Death tiebreaker panels to uniform bg-slate-900/60 border border-slate-800 rounded-xl p-3 flex flex-col justify-between styling. Eliminates border weight and color mismatches while preserving semantic title highlights.

Unified the badge styling for Seasons & Tournaments, Opponent Matrix, and Upcoming Matches to a clean, consistent bg-slate-800 border border-slate-700/60 text-slate-300 font-mono badge pill.

Replaced sporadic raw unicode emojis across event badges, season dates, and list headers with sharp Lucide SVG icons (zap, calendar, trophy), reserving emojis strictly for podium medal rankings (🏆 1st, 🥈 2nd, 🥉 3rd).

Added complete double-elimination Week 8 Playoff tournament intelligence. Features a dedicated Week 8 Playoffs tab in the League Dossier modal, Playoff KPI summary cards (Tournament Champion, Enrolled Throwers, Playoff Clutches, Big Axe Deciders), full playoff standings with podium medals (🏆 1st, 🥈 2nd, 🥉 3rd), match records, SPA, sweeps, and tiebreaker deciders.

Implemented a high-performance multi-tier caching architecture combining persistent SQLite storage and in-memory client caching. Re-opening league dossiers is now instantaneous (0ms in-memory, ~8ms SQLite cache hit), completely eliminating the ~2,400ms upstream AxeScores API latency bottleneck.

Replaced the 3MB runtime Tailwind Play CDN with a pre-compiled, tree-shaken 34KB minified stylesheet (tailwind.min.css). Refactored monolithic templates into modular Jinja2 components (templates/components/, templates/modals/) and extracted client analytics scripts into cached static JavaScript (/static/js/app.js).

Enhanced modal and table accessibility with standard role="dialog", aria-modal="true", scope="col" attributes, and global Escape key dismissal for modals and search dropdowns.

Complete interactive season dossier with real-time league-wide KPI summary cards (League Average, Bullseye Accuracy %, Enrolled Throwers, Total Matches), full standings table with 7-point clutches and perfect games (81s/15s), and 8-week match pairings.

Pre-scheduled future matches (Not Started, 0-0) are clearly marked with neutral Upcoming badges and isolated from win/loss records, scoring averages, clutches, and rating impact.

Removed synthetic per-match date interpolation in favor of official AxeScores tournament and season date ranges. Single-day marathon tournaments and multi-week leagues are strictly distinguished and preserved.

Refined global search ranking and automatic deduplication across player directory indexes to ensure rapid, collision-free profile lookup.

Granular scoring breakdown across regulation throws 1 through 5 (7s, 5s, 3s, 1s, 0s), clutch calling accuracy, and aimed bullseye precision.

Win rate and scoring breakdown categorized by opponent scoring average tiers (Elite ≥68, Competitive 62-67.9, Mid-Tier 55-61.9, Developing <55).

Built with zero tracking, local SQLite caching, 1-hour cooldown protections, and transparent open-source architecture.
