• Centralised known API route and method declarations so JSON 405 handling and published contracts use one catalogue.
• Added API and contract revision response headers.

No existing request or response field was removed or renamed.

2026-08-02 — Canonical API subdomain

• New integrations use https://api.vettiguard.com/v1.
• https://vettiguard.com/api/v1 remains operational for existing integrations.
• Legacy responses carry migration headers that identify the canonical URL.
• No sunset date is currently assigned to the legacy base URL.

Compatibility policy

• New optional response fields may be added without a major API version change.

• Added internal release-lock, migration-catalog, deployment-packet, and rollback-packet tooling for system operators.
• Added a blocking exact-RC identity gate to production release execution.

2026-08-10 — Phase 82 exact-release production evidence binder (no contract change)

Phase 82 changes only the system-admin release/launch control plane. New validation evidence is bound to the exact package version and manifest checksum, and System > Releases & upgrades can read/download a private production-evidence binder. No public /api/v1 route, request field, response field, SDK contract, or OpenAPI operation is added or changed. The public API remains at 121 operations with contract version 2026-08-08.3.

2026-08-11 — Phase 82.1

• Browser widget hotfix: routine challenge/token expiry now silently renews challenge state instead of rendering an expiry error card.
• Pending protected-form submissions are preserved and automatically resumed after fresh verification.
• Browser lifecycle state/events now distinguish ready, challenging, verified, stale, refreshing, and failed conditions.
• Built-in CAPTCHA chrome is merchant-neutral and shows only “Protected by VettiGuard”; effective branding responses neutralise account display name/logo for compatibility with older widget builds.
• No new public HTTP operation; contract remains 2026-08-08.3 with 121 operations.

2026-08-11 — Phase 82.2

• Browser-only hotfix; public HTTP contract remains 2026-08-08.3 with 121 operations.
• Idle challenge/token expiry no longer creates continuous replacement-challenge traffic.
• VettiGuard.getState(container) can report challenge_stale; fresh challenge state is obtained at interaction/protected-action time.
• Successful widget chrome is reduced to a compact checked Verified state with no visitor-facing token implementation details.
• Phase 82.1 neutral identity remains unchanged: Protected by VettiGuard only.
