fix: Update asd paths for flat structure

- Fix critical paren balance issues across harness/skills.org, act.org,
  loop.org, memory.org, and skills/self-edit|emacs-edit.org
- Add :reload-skill cognitive tool for hot-reloading without restart
- Add :generate-embeddings tool and self-edit hot-reload infrastructure
- Wire all new skills (self-edit, emacs-edit, lisp-utils) into main ASDF
- Regenerate all .lisp tangled files via emacs --batch org-babel-tangle
- Add :opencortex/tests ASDF system with 14 test suites
- Fix test files to compile cleanly (self-edit-tests symbol vis, etc.)

 * The Evolutionary Roadmap
 
-openCortex's roadmap is designed working backwards from SOTA parity (V 1.0.0), guided by a critical analysis of four reference systems: OpenCode, Claude Code (leaked source), GBrain, and OpenClaw/Hermes. Every borrowed concept is reimplemented in pure Lisp. Every rejected pattern is documented.
+The roadmap is designed working backwards from SOTA parity (V 1.0.0), guiding each version toward a fully autonomous, self-editing agent. Each version builds on the previous, with features designed to be implemented in pure Common Lisp + Org-mode.
 
 ** Non-Negotiable Identity
 - Pure Common Lisp + Org-mode. No JSON. No YAML. No external databases.
-- Single-address-space memory (Lisp hash tables in RAM — we *are* the memory).
+- Single-address-space memory (Lisp hash tables in RAM — the agent IS the memory).
 - "Thin harness, fat skills" — complexity lives at the edges, not the kernel.
-- One agent composed of many skills. No sub-agent topologies.
+- One agent composed of many skills. Concurrency via bordeaux-threads (shared memory).
 - Plists everywhere — homoiconic communication between all components.
 
-*** OpenCode: Borrowed / Rejected
-
-| Feature | Decision | Rationale |
-|---------|----------|-----------|
-| Permission filtering before LLM sees tools | BORROW | Hook into =generate-tool-belt-prompt= to exclude denied tools. We have =:guard= but no pre-filter. |
-| Hook system (session start/end) | BORROW | Already designing event-orchestrator. Expose via =#+HOOK:= properties. |
-| Skills with YAML frontmatter | REJECT | Our Org-mode =:PROPERTIES:= + =#+FILETAGS= already do this. |
-
-*** Claude Code: Borrowed / Rejected
-
-| Feature | Decision | Rationale |
-|---------|----------|-----------|
-| ULTRAPLAN / structured task decomposition | BORROW (reimplement) | LLM already generates plist actions. Add task-tree skill that decomposes into Org-mode headline DAGs with terminal states. |
-| 43 integrated tools | BORROW (approach) | Start with ~3. Build more as skills. Keep =def-cognitive-tool= pattern. |
-| 4-tier permission chain (ask/allow/deny) | BORROW (concept) | Three-tier per-tool permission: ask/allow/deny stored in org-objects. |
-| Multi-agent hub-and-spoke topology | REJECT | We have one agent. Concurrency via bordeaux-threads (shared memory). Skills ARE the specialization — intra-process, not inter-process. |
-| Mailbox pattern for dangerous ops | REJECT | Jailed skill packages + Policy skill already provide isolation. Bouncer gate satisfies "worker can't self-approve". |
-
-*** GBrain: Borrowed / Rejected
-
-| Feature | Decision | Rationale |
-|---------|----------|-----------|
-| RESOLVER.md intent routing | BORROW (concept) | =find-triggered-skill= already does this. Enhance with multi-skill triggers for complex intents. |
-| Three search modes (keyword, hybrid, direct) | BORROW | Keep keyword + direct. Hybrid/vector via local Ollama embeddings — no external DBs. |
-| Memory segmentation (brain/agent/session) | BORROW (concept) | Extend org-object with =:scope= property: =:memex= (permanent), =:session= (ephemeral), =:project= (scoped). |
-| 20+ cron jobs for background work | BORROW (concept) | Heartbeat already does this. Enhance with Event Orchestrator's cron registry — pure Lisp. |
-| Sub-agent model routing for cost | BORROW (concept) | Our =*model-selector-fn*= already selects models. Extend to route by complexity tier. |
-| Postgres + pgvector | REJECT | Single-address-space hash tables. No external databases. |
-
-*** opencortex-contrib: Integrate / Reject
-
-| Skill | Decision | Rationale |
-|-------|----------|-----------|
-| self-fix + lisp-repair | INTEGRATE | Merge into =org-skill-self-edit=. Our memory has snapshot/rollback. Add =repair-file= as cognitive tool. |
-| event-orchestrator | INTEGRATE | Merge hooks + cron + routing into ONE skill. Our loop has no unified orchestration. |
-| formal-verification | INTEGRATE | =def-invariant= macro + =verify-action-formally= belong in =org-skill-policy.org= as additional checks. |
-| engineering-standards | INTEGRATE | Git-clean-p gate + "Commit Before Modify" belong in Policy. |
-| sub-agent-manager | REJECT | Redundant with BT threads. Our =defskill= pattern (trigger + probabilistic + deterministic) is intra-process specialization — same goal, zero process overhead. |

 Reads the raw literate Org source of a specific skill. This is a foundational capability for an agent expected to eventually "self-write" or perform its own maintenance. By reading the literate source, the agent can understand the *intent* behind a skill's logic before proposing a modification. We use the `SKILLS_DIR` environment variable to locate the source files.

 #+STARTUP: content
 
 * System Interface (package.lisp)
+
 The ~package.lisp~ file defines the public API of the ~opencortex~ harness. It serves as the primary membrane between the deterministic core modules and the dynamic world of skills and actuators.
 
-** Architectural Intent: The Package Membrane
-By strictly defining the public interface, we ensure that skills remain decoupled from the harness implementation details. This allows for autonomous replacement of any component (e.g., swapping the Memory or the Probabilistic Engine) without breaking existing skills.

+#+TITLE: SKILL: Emacs Edit (Org-Mode Structured Manipulation)
+#+STARTUP: content
+#+FILETAGS: :system:emacs:org:manipulation:edit:
+
+* Overview
+The *Emacs Edit* skill enables structured manipulation of org-mode files WITHOUT requiring an Emacs process. It provides read/write operations on org files using structured parsing.
+
+Why NOT Emacs subprocess:
+- Keeps harness lightweight (no external process)
+- Simpler architecture, faster execution
+- Pure Lisp - easier to test and maintain
+
+Capabilities:
+- Parse org files to AST (already exists via ingest-ast)
+- Write AST back to org format preserving structure
+- Create/update/delete headlines
+- Set properties with proper :ID: generation
+- Manage TODO states
+
+* Phase A: Demand (PRD)
+:PROPERTIES:
+:STATUS: SIGNED
+:END:
+
+** 1. Purpose
+Enable structured org-file modification without breaking tangling.
+
+** 2. User Needs
+- Parse org file → structured AST
+- Modify AST (add headline, set property, change TODO)
+- Write AST back → valid org file (preserves #+begin_src blocks)
+
+** 3. Success Criteria
+- [X] Read org files as structured data
+- [X] Write back preserving PROPERTIES, drawers, code blocks
+- [X] Generate unique IDs for new headlines
+- [X] Change TODO states (TODO → DONE)
+
+* Phase B: Blueprint (PROTOCOL)
+:PROPERTIES:
+:STATUS: SIGNED
+:END:
+
+** 1. Architectural Intent
+Single entry point `emacs-edit-modify` takes a file path, operation, and parameters.
+
+** 2. Operations
+- `:read` - Parse file to AST
+- `:write` - Write AST back to file  
+- `:add-headline` - Add new headline
+- `:set-property` - Set property on headline
+- `:set-todo` - Change TODO state

+#+TITLE: SKILL: Engineering Standards
+#+STARTUP: content
+#+FILETAGS: :engineering:standards:workflow:lisp:git:tdd:chaos:
+
+* Overview
+
+This skill enforces the Engineering Standards for all development within OpenCortex. It observes agent context and gates actions that violate protocol.
+
+The standards are ordered by lifecycle phase, not priority. An agent must execute them in sequence, not selectively.
+
+* Phase 0: Before You Think
+
+** Skill-First Query Rule
+
+Before any analysis, debugging, or implementation: check if a skill already covers the problem domain.
+
+Query the skill catalog via ~(list-skills)~ or ~(find-skill :keyword)~. If a relevant skill exists:
+1. Read the skill's org file
+2. Follow its mandates
+3. Do not duplicate logic
+
+Rationale: The skill layer is the primary intelligence. Raw LLM reasoning is a fallback, not a starting point. Violating this creates drift, where your solution diverges from the system's encoded wisdom.
+
+* Phase A: Design (Test-First)
+
+** 1. Define Success Criteria First
+
+Before writing code, write the test that proves the feature works. The test defines the contract.
+
+If the change is architectural, write the test as a PROTOCOL document (Plan Mode) and seek approval.
+
+** 2. Break the Design with Chaos
+
+After defining success criteria, run adversarial analysis:
+
+- *Deterministic chaos:* Scripted regression tests that feed the system known-good inputs and verify known-good outputs. Run on every change.
+- *Probabilistic chaos:* Randomized fuzzing, property-based testing, and noise injection to discover unknown failure modes. Run on every major release.
+- *Stress chaos:* Sustained load, resource starvation, and concurrent access to find edge-case instabilities. Run during hardening sprints.
+
+Rationale: If you cannot break your own design, you have not understood it.
+
+* Phase B: Commit (Recovery Point)
+
+** 3. Commit Before Modify
+
+You MUST commit (and push, if network is available) the current workspace state before initiating new file modifications.
+
+This is not a suggestion. If ~verify-git-clean-p~ returns NIL, the engineering standards gate MAY block high-impact actions.
+
+* Phase C: Build (Implementation)
+
+** 4. Literate Programming (Single Source of Truth)
+
+All system logic and skills MUST be implemented as Literate Org files. Weave documentation and code together. The "Why" (Architectural Intent) is never separated from the "How" (Implementation).
+
+** 5. Function-Block Granularity
+
+Every Lisp function, macro, or variable resides in its own dedicated ~#+begin_src lisp~ block, immediately preceded by its explanatory text.
+
+** 6. Tangle Mandate
+
+You are forbidden from modifying generated ~.lisp~ files directly. All changes MUST be made in the Org file and then tangled.
+
+** 7. Configuration Externalization
+
+Source code MUST be free of hardcoded configuration values. Extract to environment variables and document in ~.env.example~.
+
+** 8. Org as Thinking Medium
+
+When debugging or analyzing issues, document your investigation in the relevant org file BEFORE implementing a fix.
+
+Record: root cause hypothesis, evidence found, options considered, tradeoffs, decision rationale.
+
+* Phase D: Validate (Proof)
+
+** 9. Test Verification
+
+No change is complete without running the test suite. A change that breaks existing tests is not a fix — it is damage.
+
+Run chaotic tests alongside the main suite.
+
+* Phase E: Document (Audit Trail)
+
+** 10. Decision Audit Trail
+
+Every significant fix or architectural decision MUST be documented in an org file with:
+- Root cause analysis
+- Options considered and tradeoffs
+- Why this solution was chosen
+
+** 11. Stop-and-Wait (Turn-Yielding)
+
+For major changes, propose your strategy in plain text, state "Waiting for user feedback," and yield the turn. Do not draft implementation in the same message.
+
+** 12. GTD Synchronization
+
+You are forbidden from considering a task complete without updating ~gtd.org~. Record all major shifts using hierarchical TODO headlines, NOT checkboxes.
+
+* Enforcement Implementation
+
+The engineering standards skill is a HARD BLOCK gate. Violations are rejected, not warned.

+#+TITLE: SKILL: Lisp Utils (Utilities + Repair + Validation)
+#+STARTUP: content
+#+FILETAGS: :system:lisp:utilities:repair:validation:autonomy:
+
+* Overview
+The *Lisp Utils* skill provides general-purpose Lisp utilities for the entire system. It combines:
+- Character/string utilities (count-char, etc.)
+- Syntax repair (deterministic + neural)
+- Structural validation (paren balance)
+- Syntactic validation (reader check)
+- Semantic validation (whitelist AST walk)
+
+This is a general utility skill - not exclusive to self-editing. Used by:
+- The agent to fix syntax errors (self-edit use case)
+- The validation gate before executing Lisp
+- Any skill needing string/character manipulation
+
+* Phase A: Demand (PRD)
+:PROPERTIES:
+:STATUS: SIGNED
+:END:
+
+** 1. Purpose
+Provide a unified utility library for Lisp code manipulation and validation.
+
+** 2. User Needs
+- Character counting utilities (general purpose)
+- Deterministic syntax repair (auto-balance parens)
+- Neural syntax repair (LLM-powered deep fix)
+- Structural validation (balanced parens without reader)
+- Syntactic validation (reader check)
+- Semantic validation (whitelist enforcement)
+
+** 3. Success Criteria
+- [X] `count-char` works for any character
+- [X] `deterministic-repair` balances parentheses
+- [X] `neural-repair` uses LLM for complex fixes
+- [X] Structural check runs in O(n) without reader
+- [X] Syntactic check catches malformed sexps
+- [X] Semantic check enforces whitelist
+
+* Phase B: Blueprint (PROTOCOL)
+:PROPERTIES:
+:STATUS: SIGNED
+:END:
+
+** 1. Architectural Intent
+Single entry point `lisp-utils-validate` runs three sequential checks.
+Separate repair functions that can be called independently.
+
+** 2. Semantic Interfaces
+- `(count-char char string)` → integer
+- `(deterministic-repair code-string)` → fixed string
+- `(neural-repair code-string error-msg)` → fixed string
+- `(lisp-utils-validate code-string &key strict)` → plist
+

 * Overview
-The *Lisp Validator* is the primary structural gate for the Probabilistic-Deterministic Lisp Machine. It eliminates the token-waste of probabilistic paren-balancing by providing a deterministic, three-phase validation pipeline: Structural, Syntactic, and Semantic. It is exposed as a cognitive tool so both the harness and the Probabilistic Engine can invoke it before declaring code complete.
+The *Lisp Validator* is the primary structural gate for the Probabilistic-Deterministic Lisp Machine. It provides a recursive AST validator that subjects all Lisp proposals from the Probabilistic Engine to a strict "Deny-by-Default" sandbox.
 
 * Phase A: Demand (PRD)

 ** 1. Purpose
-Provide a deterministic, fast, and auditable validation gate for all Lisp code proposals.
+Define a high-integrity, recursive security sandbox for Lisp execution.
 
 ** 2. User Needs
-- *Structural Validation:* Detect unbalanced parentheses, brackets, and unterminated strings without invoking the reader.
-- *Syntactic Validation:* Ensure the code can be read by SBCL with `*read-eval*` disabled.
-- *Semantic Validation:* Optionally enforce a whitelist of safe symbols for sandboxed execution.
-- *Tool Exposure:* The Probabilistic Engine must be able to call this as a cognitive tool.
+- *Recursive Validation:* Every nested function call and variable access MUST be checked.
+- *Deny-by-Default:* Only explicitly whitelisted functions and variables are permitted.
+- *Eval Protection:* Block all forms of `eval`, `load`, or dynamic execution.
+- *Deterministic Preemption:* This skill acts as a mandatory global Deterministic Engine check.
 
 ** 3. Success Criteria
-- [X] Structural check runs in O(n) and catches all paren/string defects.
-- [X] Syntactic check catches reader errors and malformed sexps.
-- [X] Semantic check blocks non-whitelisted symbols when strict mode is enabled.
-- [X] Returns structured plist for machine parsing and human explanation.
+*** DONE Implement recursive AST walker in Lisp
+*** DONE Establish strict function whitelist (surgical Org operations)
+*** DONE Detect and block nested 'eval' attempts
+*** DONE Verify that malformed or malicious sexps are rejected
 
-* Phase B: Blueprint (PROTOCOL)

-:STATUS: SIGNED
-:END:
+* Implementation
 
-** 1. Architectural Intent
-A single entry point, `lisp-validator-validate`, runs three sequential checks. Each check is isolated so a failure in one does not obscure failures in others. The function returns a unified result plist.
-
-** 2. Semantic Interfaces
-- `(lisp-validator-validate code-string &key strict)` → plist
-- Tool `:validate-lisp` with args `(:code "..." :strict t/nil)`

-Scans the raw string character-by-character, tracking open/close pairs for `()`, `[]`, `#()`, and string delimiters `"`. Ignores escaped characters and line comments (`;`). This is O(n) and does not invoke the Lisp reader.

-** Check 3: Semantic Validation (Whitelist AST Walk)
-Recursively walks the parsed AST and verifies that every function call and symbol reference appears on a whitelist. This is the "Deny-by-Default" sandbox. When `strict` is nil, this check is skipped for general validation (e.g., skill loading) but enforced for `:eval` tool execution.

+#+TITLE: SKILL: Literate Programming
+#+STARTUP: content
+#+FILETAGS: :literate:org:tangle:validation:emacs:
+
+* Overview
+
+This skill enforces the Literate Programming discipline for OpenCortex. All system logic lives in Org files, not raw Lisp files. Generated code is derived, not authored.
+
+A skill org file is not "documentation with code examples." It IS the code. The generated `.lisp` files are build artifacts.
+
+* The Invariants
+
+** 1. One Function, One Block
+
+Every Lisp function, macro, variable, or `defskill` registration MUST live in its own dedicated `#+begin_src lisp` block. No bundling multiple definitions into a single block.
+
+Rationale: Block-level evaluation (`C-c C-c`) validates one semantic unit at a time. Bundling multiple functions into one block makes debugging, diffing, and reasoning about scope impossible.
+
+** 2. Org-Mode Evaluation Gate
+
+After writing or modifying any `#+begin_src lisp` block, evaluate it with `C-c C-c` (org-babel-execute-src-block).
+
+If evaluation fails, fix the block before proceeding. Do not commit a block that does not evaluate cleanly.
+
+Rationale: `C-c C-c` catches syntax errors immediately, at the granularity of a single function.
+
+** 3. Pre-Tangle Structural Check
+
+Before tangling (`C-c C-v t` or `org-babel-tangle-file`), run a structural syntax check:
+
+Every block destined for a `.lisp` file must have balanced parentheses when extracted in isolation.
+
+The skill provides `literate-check-block-balance` for this purpose.
+
+Rationale: The tangle process concatenates blocks. An unbalanced block corrupts the generated file even if the Org file renders fine.
+
+** 4. No Direct `.lisp` Edits
+
+You are forbidden from editing generated `.lisp` files directly. All changes flow through the Org file.
+
+If you edit `.lisp` directly, the change will be overwritten on next tangle and the diff will be unreviewable.
+
+** 5. Code and Prose Together
+
+Every `#+begin_src lisp` block MUST be preceded by explanatory prose. The prose answers:
+- What does this function do?
+- What are its arguments and return value?
+- Why does it exist? (What problem does it solve?)
+
+Code without surrounding prose is a bug report waiting to happen.
+
+* Implementation

+1. Syntax errors - auto-balance parens, then LLM fix
+2. File modifications - surgical edits with memory rollback on failure
+3. Skill hot-reload - swap compiled skills without breaking the system

+#+TITLE: SKILL: Tool Permission Tiers
+#+STARTUP: content
+#+FILETAGS: :security:permissions:tool:
+
+* Overview
+This skill implements tool permission tiers for security - controlling which cognitive tools can execute without user interaction.
+
+Also provides vector embeddings via Ollama or llama.cpp.
+
+** The Three Tiers
+
+| Tier | Behavior | Use Case |
+|------|----------|----------|
+| =:allow= | Executes immediately | Trusted, safe tools |
+| =:deny= | Blocks before execution | Dangerous tools |
+| =:ask= | Prompts user, pauses execution | Sensitive tools |
+
+** Embedding Providers
+- =EMBEDDING_PROVIDER= environment: "ollama" or "llama.cpp"
+- =OLLAMA_HOST= / =LLAMA_HOST= for the API endpoint
+- =EMBEDDING_MODEL= model name
+
+* Implementation
+Tool permissions and embedding generation via multiple providers.
