Changelog

September 14, 2026

Added a sanitized structural snapshot for intentionally public API operations.
Added cryptographic endpoint and whole-contract fingerprints derived from the production API contract without publishing private schemas or implementation metadata.
Added CI validation requiring the snapshot endpoint set to match the explicit public allowlist exactly.
Added the contract snapshot to the Public Release Firewall and machine-readable documentation routing.
Established production-to-docs drift detection so approved public API structure cannot change silently.

Added a fail-closed publication firewall to the required documentation CI check.
Added an allowlisted public-contract boundary for WEDNESDAY origins and explicit HTTP endpoint declarations.
Added source and generated-site leakage scanning plus regression tests.
Excluded repository governance, policy, tests, and security-maintenance files from the GitHub Pages artifact.
Tightened the API reference so operational service metadata and probes are not part of the published developer contract.

Established docs.wednesdaychat.com on GitHub Pages.
Configured the custom domain and enforced HTTPS.
Established main as the production documentation branch.
Added the initial public documentation architecture and machine-readable discovery files.

Platform feature changes will be listed here only when verified against the relevant production contract.
