REINOW-WP-0001	Bootstrap: minimal open-weight agentic loop	finished	6fbd6531-5e66-519c-9cf2-b987fe7c3c61

First working milestone for rein-openweights: prove an agentic tool-use loop against a current open-weight model via OpenRouter, comparable in scope to rein-aharness's green-commit-only profile, implementing the glas-harness rein contract (glas-harness/GLAS-WP-0001-T01).

Live-proven end-to-end (2026-07-26): via glas-harness's gateway (glas_harness.reins.rein_openweights.ReinOpenWeights), inside a real ext.bwrap sandbox, against the real OpenRouter API with model qwen/qwen-2.5-72b-instruct — a 2-turn tool-calling loop produced a real git commit (2effe57a), verified via git rev-parse HEAD, 2449 tokens spent. Not a mock; real credentials, real API cost, run with the user's explicit go-ahead. executor-sandbox (the disposable target repo) was left untouched — bwrap only mutates its ephemeral copy.

Task: Pick the starter open-weight model + OpenRouter path

Checked llm-connect's existing OpenRouter integration (OpenRouterAdapter.execute_prompt): it takes a single prompt string, builds a fixed [system, user] message pair itself, and never surfaces message.tool_calls in its response — it cannot drive a multi-turn tool-calling loop without a breaking change to llm-connect's frozen Core LLMAdapter ABC. Decision: rein-openweights uses its own minimal OpenRouter client (openrouter_client.py) for the agentic loop instead; tools/tool_choice already pass through llm-connect's own OPENAI_CHAT_PASSTHROUGH_FIELDS allow-list, confirming the request shape is standard OpenAI-compatible function-calling, just not round-tripped by that adapter today. Starter model is a --model-configurable default (meta-llama/llama-3.1-70b-instruct), not hardcoded.

Task: Minimal agentic loop

Implemented in loop.py + tools.py: plan → tool call → observe → repeat with a hard tool allow-list matching rein-aharness's green-commit-only (read_file/write_file/edit_file/glob_files/ grep_files + git_status/git_diff/git_log/git_add_commit, no push/network/shell), bounded by max_turns and a token budget. Budget tracker is vendored locally (budget.py), not llm-connect's — consistent with T01/ADR-002 keeping llm-connect optional. Path-traversal guarded (_resolve); tool errors are reported back to the model as a role: tool message rather than crashing the loop. 26 tests, all mocked at the httpx/subprocess boundary.

Task: Success criterion + reporting

Implemented in runner.py/hub.py: a local git commit is the sole success signal (RunResult.ok == committed), State Hub progress event (executor_run) and token event posted on completion via a hub module mirroring rein-aharness's, --no-hub to skip. Not yet exercised against a live State Hub call in this pass (mocked in tests) — same caveat as rein-aharness/glas-harness's own not-yet-live-run notes elsewhere in this rein family.

Task: Credential brokering

Resolved by glas-harness docs/adr/ADR-002-credential-brokering-and-composable-reins.md (Option B): rein-openweights acquires its own OpenRouter credential. Implemented in credentials.py, mirroring rein-aharness's mailscan.py OpenBao AppRole/ambient-token pattern (explicit env var → AppRole exchange → ambient token → single kv get). glas-harness does not broker this.

Task: Forgejo repo creation

Operator created coulomb/rein-openweights.git on Forgejo (stub with LICENSE + README). Local history merged in with --allow-unrelated-histories (kept the local README, took the stub's MIT LICENSE — matches the sibling rein repos), pushed to origin/main, registered with State Hub (domain: infotech, wp-prefix: REIN-OW). Repo is no longer local-only.
