**Released:** 2026-06-29 (versions 0.5.0 through 0.5.3)

## What's in v0.5

### Deep-Research Verified Content (Sprint 6)

v0.5 introduces OKF content generated from a 104-agent deep-research workflow with adversarial verification (3-vote majority per claim). Only claims reaching 2-of-3 or 3-of-3 agent agreement were published. Claims that failed verification are explicitly excluded and noted in affected files.

**6 new adversarially verified dossier files:**

| File | Key claim | Confidence |
|------|-----------|------------|
| `suryavanshi-72-sixes` | 72 sixes in IPL 2026 — IPL single-season record | 3-0 |
| `suryavanshi-youngest-500-runs-ipl` | Youngest to 500+ IPL season runs (15y 27d) | 2-1 |
| `kohli-9000-ipl-runs` | First batter to 9,000 IPL career runs (April 27 2026) | 3-0 |
| `kohli-ipl-2026-final` | 75* off 42 balls, fastest IPL fifty (25 balls), PoM | 3-0 |
| `ipl-2026-chase-dominance` | 8 of 12 early-phase matches won by chasers | 3-0 |
| `impact-player-rule-controversy-2026` | Axar Patel opposition; top-5 run chases all post-2023 | 3-0 / 2-1 |

**4 new advanced metric files (research gaps confirmed):**

| File | Content |
|------|---------|
| `fantasy-cricket-strike-rate` | Dream11 IPL SR tiers (-6 to +6 points), 10-ball minimum floor |
| `expected-runs-xR` | Delivery-difficulty-adjusted batting metric; academic concept (CricketSavant 2016) |
| `expected-wickets-xW` | 50-nearest-neighbour wicket probability; academic concept (CricketSavant 2017) |
| `win-probability` | Two-model chain (first-innings + chase model); Win Probability Added (WPA) |

**Claims excluded after verification failure:**
- IPL 2026 Final specific scorecard (GT 155/8, RCB 161/5) — refuted 0-3 by secondary sources
- "All ten captains opposed the Impact Player Rule" — refuted 0-3
- "BCCI refused rule change until 2027" — refuted 0-3
- Suryavanshi prior-record holder single-season sixes count (Gayle's count) — refuted 0-3

### 4 Impact Player Narrative Stories (v0.5.1)

- `impact-player-captains-dilemma` — "The Card You Can Only Play Once"
- `impact-player-rule-alone` — "The Rule That Only IPL Dared Try"
- `impact-player-bowlers-displaced` — "The All-Rounder's Dilemma"
- `ipl-2026-most-impactful-player` — "The Most Impactful Player of IPL 2026 (Both Meanings)"

### SEO Schemas + Viewer

- FAQPage, BreadcrumbList, and Article JSON-LD on dossier and story pages
- Type-aware `<title>` suffix enrichment per page type
- WebSite schema + SearchAction on homepage (Google Sitelinks Searchbox)
- Per-page OG images: 135 unique images for stories, dossier, research, metrics (v0.5.2/v0.5.3)
- `.well-known/ai-plugin.json` — OpenAI plugin manifest for agent discovery

### Google OKF Alias Field Coverage

All 532 OKF files now include:
- `resource` — alias for `canonical_page` (Google OKF alignment)
- `timestamp` — alias for `last_verified` (Google OKF alignment)

Validator result: **532 files, 0 errors, 0 warnings** (was 681 warnings at v0.4).

`scripts/fix_okf_aliases.py` added as a reusable idempotent maintenance tool.

### 7 World-Class Sprint Dossiers + 5 Metrics (also in this release)

Dossiers: `fastest-century-ipl`, `best-spin-bowler-ipl-2026`, `ipl-2026-best-team`, `best-powerplay-batter-all-time-ipl`, `ipl-vs-other-t20-leagues`, `ipl-salary-cap-explained`, `best-all-time-death-bowler-ipl`

## Bundle Size

532 files at initial release (2026-06-29) · 45 stories · 19 metrics · 83 dossiers. Bundle has grown substantially since — see [manifest.yaml](/manifest.yaml) for current counts.

## Conformance Level

Level 3 — Agent-Safe. Self-certified 2026-07-08.

Initial release (2026-06-29) shipped at Level 2. Elevated to Level 3 within the v0.5.x series when Trust OS v1 was committed on 2026-07-08, adding: machine-readable claim ledger (`/claims.jsonl`), JSON Schema (`schema/claim-object.schema.json`), eval benchmark (`/evals/cricket-qa-v1.jsonl`, 1,000 rows), and trust manifest (`/trust-manifest.json`).

## Breaking Changes

None. All existing file paths and entity IDs unchanged.

## Security

`ROADMAP.md` (internal Claude Code planning document) was inadvertently committed during this sprint and immediately removed. Added to `.gitignore` to prevent recurrence. No sensitive data, credentials, or proprietary feed data were exposed — confirmed by full repository security audit.
