# cortex-sft-300

Phase 1 output of the Ornith-9B-CORTEX build (see `docs/CUSTOM-MODEL-BUILD-PLAN.md` in
[Johnny5b/portable-ai-runner](https://huggingface.co/datasets/Johnny5b/portable-ai-runner)).

**304 validated chat-format examples** (`{"messages": [user, assistant]}`), grown deterministically
(seed 20260920) from the 14 seed examples in `data/cortex_sft.jsonl` of portable-ai-runner plus the
repo's own source corpora: `symbols/symbol_evolution_index.json`, `docs/CORTEX-SYSTEM-PROMPT.md`,
`docs/EVO-SKILLS-BRIDGE.md`, `docs/CORTEX-LOOP-PHASE.md`, `docs/CORTEX-POINTER-ARCHITECTURE.md`,
`docs/SYMBOL-TEMPLATE.md`, `docs/BENCHMARKS.md`, `docs/CORTEX-AWAKE-PHASE.md`,
`docs/CORTEX-REPAIR-PHASE.md`.

## Validation (every example, `data/validation_report.json`)

- exactly one user + one assistant message
- assistant answer starts with the verbatim trace header `[TRACE: §R:<target> | §T:<tool> | §S:<AWAKE|REPAIR|REST>]`
- RST scaffold present (`Claim:` … `Synthesis:`)
- length bounds, no placeholders, sha256 dedupe (0 dropped)

## Honesty ledger

- Scripted generation, no LLM in the loop — templates + parsed registry/docs, so every symbol,
  commit hash, and tok/s figure is quoted from the source files, not invented.
- Benchmark numbers embedded in `routing_benchmarks` examples are the measured values from
  `docs/BENCHMARKS.md` with their HF job IDs.
- Additive: the 14 seed examples are included unmodified.
