- src/glas_harness/contract.py: Rein ABC (start_session/dispatch_tool/
end_session), SandboxHandle/ToolCall/ToolResult, per docs/harness-contract.md.
- reins/rein_aharness.py: adapter around the rein-aharness CLI. Collapses
a whole `agent-harness run` into one dispatch_tool call for now (no
per-tool hooks yet — tracked in rein-aharness HARNESS-WP-0002-T03);
verifies success via new-commit detection, mirroring rein-aharness's
own success signal.
- gateway.py + cli.py: resolves a sand-boxer sandbox, runs one task
through a rein, tears the sandbox down.
- registry/reins/*.yaml (rein-aharness implemented, rein-openweights
planned) and profiles/harness.agent-dev{,-local}.yaml, pairing with
sand-boxer's profile.agent-dev and the new profile.bwrap-local.
Tested against a real local git repo + mocked SandboxManager/CLI
subprocess (10 tests, all passing). A real live run against the actual
Claude Code CLI is deliberately left for a human-triggered follow-up —
not executed autonomously since it spends real API credits/credentials.

start_session/dispatch_tool/end_session, mirroring sand-boxer's
SandboxExtension ABC one layer up: sand-boxer establishes where work
runs, this contract governs how an agent session runs on top of it.
Unblocks the rein-aharness parity proof (T04) and rein-openweights
bootstrap (T05).

Establishes glas-harness as the framework routing between concrete
harness backends ("reins"): rein-aharness (renamed from agent-harness)
and the newly chartered rein-openweights. GLAS-WP-0001 defines the
harness contract, rein registry, and a minimal gateway proving parity
against rein-aharness.
