Phase 1 — dedup + hardening (~9 items): - Remove duplicate *skill-registry* defvar from core-skills - Merge *backend-registry* into *probabilistic-backends*, delete backend-register - Remove inject-stimulus alias, standardize on stimulus-inject - Add pre-eval sandbox (skill-source-scan) blocks restricted symbols before eval - Remove dead plist-get function; remove duplicate json-alist-to-plist export - Fix read-framed-message whitespace DoS (4096-iteration max) - Add *read-eval* nil to dispatcher-approvals-process read-from-string (RCE) - Add test-op to ASDF; update .asd version 0.4.3→0.7.2 Phase 2 — prose + contracts + reorder: - Split ROADMAP: 2623→1089 lines (TODO only), CHANGELOG: 260→1528 lines (full DONE history, 14 versions reverse chron) - Add Contracts + Overview to 6 channel files + embedding-native + programming-standards + symbolic-scope - Reorder 28 .org files: Contract → Test Suite → Implementation (TDD order) - Add 7-phase inline prose to think() in core-reason - Expand USER_MANUAL: 183→461 lines (10 new sections) Phase 3 — decomposition + export organization: - Decompose think() into think-assemble-prompt, think-call-llm, think-parse-response orchestrator - Organize 188 exports into 16 grouped sections by module Phase 4 — budget enforcement + error protocol: - Per-session budget enforcement (SESSION_BUDGET_USD env var, budget-exhausted-p, guard in think-call-llm) - Error condition hierarchy (6 conditions: pipeline-error, llm-error, gate-error, budget-error, protocol-error) - Restarts in loop-process: skip-signal, use-fallback, abort-pipeline

SKILL: Protocol Validator (org-skill-protocol-validator.org)
Overview
The Protocol Validator enforces schema compliance on every message entering or leaving the cognitive pipeline. It checks that messages are valid plists, that they have the required :type and :payload fields, and that the type is one of the known types (:REQUEST, :EVENT, :RESPONSE, :LOG, :STATUS). This prevents malformed messages from crashing the pipeline and ensures backward compatibility when the protocol evolves.
Architectural Intent
The Protocol Validator wraps validate-communication-protocol-schema
(the core communication function) in a skill-level gate. It is the first
filter every message passes through — malformed messages are rejected
before they reach any cognitive stage.
Contract
- (validator-protocol-check msg): returns
msgif valid pervalidate-communication-protocol-schema. Signalserroron malformed messages (caught by the skill's deterministic gate). - The skill's deterministic gate wraps the validator: valid actions pass
through; invalid actions produce a
:LOGrejection with:level :error.
Boundaries
- Does NOT define the schema — that is
core-transport.org. - Does NOT validate semantic content — that is the Dispatcher and Policy.
