Changelog

1.23.1 - 2026-05-25

Added interface block to plugin.json (displayName, capabilities, brandColor, privacy/TOS URLs)
Added UTM-tagged homepage URL
Added MCP keyword to plugin keywords
Version aligned with ThumbGate core

Unified ThumbGate branding across all public surfaces (README, AGENTS.md, CLAUDE.md, GEMINI.md, landing page, package.json).
Landing page SEO: "human-in-the-loop enforcement", "vibe coding" positioning, FAQPage JSON-LD schema for Google rich results.
Added congruence CI check (scripts/check-congruence.js) — enforces version, branding, tech stack terms, and honest disclaimer across README and landing page on every PR.
Performance: deferred non-critical side-effects in captureFeedback (contextFs, RLAIF self-audit) via setImmediate.
Added _captureMs timing field to accepted feedback responses for observability.
Added mcpize.yaml to version sync targets.
Dead code removal: -1,551 lines (contract-audit.js, prove-rlaif.js, stale landing-page.html, 3 duplicate docs).
Fixed GitGuardian incident #29200799: scrubbed hardcoded Google API key from git history.
Social automation pipeline: post-everywhere CLI, reply monitor with AutoMod-safe Reddit posts.
TDS article draft: "Beyond Prompt Rules: How Pre-Action Gates Stop AI Coding Agents From Repeating Mistakes".

Lesson DB: SQLite + FTS5 full-text search replaces linear Jaccard token-overlap. Sub-millisecond ranked search indexed by signal, domain, tags, importance.
Corrective actions: On negative feedback, capture_feedback returns correctiveActions[] — top 3 remediation steps inferred from similar past failures.
search_lessons MCP tool: Exposes corrective actions, lifecycle state, linked rules, linked gates, and next harness fixes per lesson.
search_thumbgate MCP tool: Searches raw ThumbGate state across feedback logs, ContextFS memory, and prevention rules.
Rejection ledger: Tracks why vague feedback was rejected with revival conditions.
Bayesian belief updates: Each memory carries a posterior that updates on new evidence; high-entropy contradictions auto-prune.

Added session_handoff and session_primer MCP tools for seamless cross-session context continuity.
New session namespace in ContextFS stores primer.json with auto-captured git state (branch, last 5 commits, modified files, working tree status), last completed task, next step, and blockers.
session_handoff records provenance events for full audit trail of session transitions.
Closes Layer 2 (primer.md) of the 5-layer memory stack — no manual primer file needed.
