From 4963044fdaeb23c38151a14ebf93a44c564f97c5 Mon Sep 17 00:00:00 2001 From: Protocol Zero <257158451+Protocol-zero-0@users.noreply.github.com> Date: Tue, 26 May 2026 10:14:08 +0000 Subject: [PATCH] docs(evidence): commit evidence/ artifacts referenced by README MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The README has pointed to `evidence/` since v1.0 ("checked-in artifacts of runs anyone can reproduce"), but the directory itself never landed — the link was dead in v1.0 / v1.1.0 / v1.1.1 / v1.1.2 readers. This commit ships the two anchor pieces: - `demo-target-run-2026-05-14/` — full ledger of a real, self-halted kernel run against examples/demo_target. 47 ledger files + README + config + raw run.log. Demonstrates planner reading history, evaluator rejecting useless patches, hard-stop firing — $0.11 / 3 runs / 276 tokens. - `repo-snapshot-2026-05-13/` — architecture, test transcript, and 5-minute terminal walkthrough captured at v0.3.0. Adds a reproducibility note pointing out that the demo run used `claude_cli` (currently on main, shipping in v1.2.0); everything else in evidence/ is reproducible against v1.1.2. No code change.

It would not show whether the kernel can *resist* a bad change, or *stop itself* before burning a budget on a dead-end strategy. Those two behaviors are the kernel's actual job. This run demonstrates both: + +### 1. Planner reads history and changes direction + +`run-0002`'s `planner_input.json` contains a `history` field with one entry — the run-0001 rejection summary. The plan it produces is materially different: + +> run-0001 plan: *"Create the file `src/feature.py` with a minimal valid Python module body (e.g., a single docstring or pass statement)"* +> +> run-0002 plan: *"Create `src/feature.py` with exact content: `def feature() -> str: return 'ok'`. Ensure `src/` directory exists. Confirm file is readable and non-empty before returning."* + +The planner did not retry the same approach. It saw the rejection reason ("no effect on score") and reached for something more substantive — a callable function rather than just a docstring. By run-0003 it had pivoted further, proposing changes to evaluator-visible behavior. **The history-injection mechanism is doing real work.** ([`ledger/runs/0002/planner_input.json`](ledger/runs/0002/planner_input.json), [`ledger/runs/0002/plan.json`](ledger/runs/0002/plan.json)) + +### 2. Evaluator rejects "syntactically correct but useless" changes + +In runs 0001 and 0002 the executor *did* produce real diffs that compiled and made the candidate commit. A naive system ("did the LLM apply the patch? yes? accept!") would have shipped both of them. The Evolution Kernel evaluator looked at the actual observation (the metric was still `score: 0.5` after the patch) and rejected them anyway, with a one-sentence reason that names the failure mode: + +- run-0001 evaluator: *"Adding an empty feature module docstring has no effect on the metrics.json score or evaluator outcome."* +- run-0002 evaluator: *"Adding a stub feature.py with a trivial function does not modify metrics.json or any evaluator logic, so the score remains 0.5 and the metric check will not pass."* + +This is the protocol's **`hard_gates_passed` vs `recommendation`** separation in action. The change technically passed the syntactic safety gate, but the evaluator's *outcome* judgment was still "reject." The `fitness` floats (0.01, 0.10, 0.00) record how strongly each candidate moved the goal — both for the human reader and for the k-branch parallel exploration that ranks sibling branches. + +### 3. Hard stop fires on the kernel's own terms + +The `max_consecutive_failures: 3` hard stop is enforced in `evolution_kernel/hard_stops.py`. It triggered exactly when it should — after three back-to-back REJECTs — and the kernel exited with a halted-state JSON dropped at [`ledger/halted/20260514T041157Z.json`](ledger/halted/20260514T041157Z.json) so a future operator (or auditor) can reconstruct what happened from disk alone. + +Total spend at halt: **$0.110 of a $10 budget** (~1%). The kernel did not "run away" — it noticed it was stuck and stopped, leaving the next operator with a clean baseline (`evolution/accepted` still pointing at the initial commit `a05ac1f`, no spurious commits merged) and a written audit trail of why. + +### 4.
