Prism Coder v15.0.0 — Drift Detection + Evidence-First Protocol

Released: 2026-05-10

The headline

AI agents can now detect when they've drifted from your stated goals mid-session, self-correct, and route alerts to the Synalux portal — using three direct Prism MCP calls, no scripts, no cron, no hooks.

What ships

🔄 Proactive session drift detection

session_save_ledger   → snapshot current state
session_cognitive_route → on_track / minor_drift / major_drift
session_compact_ledger + session_load_context → reset if needed

When major_drift is detected, an alert is posted to synalux.ai/api/v1/prism/memory so the drift is visible across sessions and devices.

Real example it caught: A training session promised BFCL ≥90% for three AI models. The agent spent 3+ hours debugging audio bugs instead. Drift check surfaced: "Training goal unmet. Layer3 corpus missing from all training sets. 0 BFCL scores measured." Session immediately re-aligned.

Skill: ~/.agent/skills/session-drift-detection/SKILL.md
Tests: 10 behavioral test cases in skills/session-drift-detection/tests.md

🛡 Evidence-first behavioral protocol

Hard gates that supersede all other agent instructions:

  1. No positive claim (done/fixed/working/90%+) without observable evidence
  2. Diagnose before asserting causes (run oscillator test before guessing audio output device)
  3. Write regression test before pushing any bug fix
  4. Training quality gate: BFCL ≥90% before "training done"
  5. 60-min drift check for long sessions

Evidence gate table maps every claim type to required proof artifact.

🔊 TTS audio protection (prism-aac)

  • PROTECT_PLAY_MS=600ms: rapid autoSpeak calls are gracefully dropped instead of killing each other
  • interrupt parameter replaces shared flag (fixes Speak button being silenced by concurrent tile taps)
  • volume=0 guard with console.warn
  • 10 unit tests covering all failure classes
  • SSML rate × 2 formula (capped at 1.4) confirmed working

🔍 Search keyboard routing (prism-aac)

  • Search opens with keyboard visible immediately
  • On-screen keys route to search input via searchKeyBridge.ts

📬 Inbox wired (prism-aac + synalux-private)

  • /api/v1/prism-aac/inbox/poll returns real Gmail unread + unclaimed SMS
  • Per-message TTS on arrival
  • Reply button on schedule message tasks

🏪 Marketplace catalog fixed (synalux-private)

marketplace_modules table created and applied to production Supabase.

13 stub fixes (synalux-private)

Accounting providers, Zoom, Telegram/WhatsApp, e-sign, feature-flags, SMS, and more.

Migration

No breaking changes to MCP tools or protocol. Update via:

npm install -g prism-mcp-server@15.0.0
npx prism-mcp-server --version  # should print 15.0.0

What's next (v15.x)

  • BFCL ≥90% verified on 72B, 32B, 2B models (in training)
  • Layer3 runtime inference server with 3-layer pipeline
  • OpenAI-compatible /v1/chat/completions with layer routing
