title: "Harness router foundation: contract + first two reins"

Turn glas-harness from a charter into the actual harness router per
|
|
`docs/adr/ADR-001-rein-harness-family.md`. Define the contract concrete
|
|
harness backends ("reins") implement, register the first two
|
|
(`rein-aharness`, `rein-openweights`), and stand up a minimal gateway
|
|
that can run a session through either. No channel work, no memory/skills
|
|
layer yet — this workplan is the sand-boxer-extension-model equivalent
|
|
for harnesses: contract + registry + one working round trip.
|
|
|
|
## Task: Define the harness contract
|
|
|
|
Specify the interface a rein implements: session start/resume/end, tool
|
|
dispatch + policy check, actor attribution (`adm`/`agt`/`atm`), sandbox
|
|
policy resolution (mode/scope/workspaceAccess) handed to sand-boxer, and
|
|
the audit envelope reported to State Hub. Mirror sand-boxer's
|
|
`SandboxExtension` ABC shape (`provision`/`wait_ready`/`teardown`) at the
|
|
harness level: something like `start_session`/`dispatch_tool`/
|
|
`end_session`. Document in `docs/harness-contract.md`.

|
|
|
|
## Task: Rein registry
|
|
|
|
A named, versioned registry of reins (`registry/reins/rein-aharness.yaml`,
|
|
`registry/reins/rein-openweights.yaml`) analogous to sand-boxer's
|
|
`extensions/ext.*.yaml` — each entry declares its capabilities (e.g.
|
|
`unattended`/`interactive`, `model-class: frontier|open-weight`,
|
|
`credential-source`) and a handler reference. Extend
|
|
`registry/indexes/capabilities.yaml` with a `capability.platform.
|
|
glas-harness` entry per the registry-first-reuse principle.

|
## Task: Harness profile catalog seed
|
|
|
|
First harness profile, `harness.agent-dev`, paired with sand-boxer's
|
|
`profile.agent-dev` (existing `docs/integrations/glas-harness.md` contract
|
|
in sand-boxer already assumes this pairing — verify it still matches).
|
|
Add a second profile, `harness.agent-dev-local`, paired with sand-boxer's
|
|
forthcoming `profile.bwrap-local` (SAND-WP-0013) once that lands, for
|
|
fast local iteration without an SSH hop.

|
```
|
|
|
|
## Task: Minimal CLI gateway — prove the contract against rein-aharness
|
|
|
|
Implement just enough of the harness contract to run one existing
|
|
rein-aharness `run` (task-file path) *through* glas-harness: resolve
|
|
`harness.agent-dev`, request a sandbox from sand-boxer, dispatch to
|
|
rein-aharness's adapter, verify commit, report to State Hub. This is the
|
|
parity proof gating any later "retire agent-harness as a standalone
|
|
concern" conversation — deliberately not attempted until this exists.

```
|
|
|
|
## Task: Charter and bootstrap rein-openweights
|
|
|
|
Turn the `~/rein-openweights` scaffold into a working minimal rein: an
|
|
agentic tool-use loop (plan → tool call → observe → repeat) driving an
|
|
open-weight model via `llm-connect`'s OpenRouter path, implementing the
|
|
GLAS-WP-0001-T01 contract. Start with the same tool surface as
|
|
rein-aharness's `green-commit-only` profile (Read/Write/Edit/Glob/Grep +
|
|
local git) so it's directly comparable. Needs its own Forgejo remote
|
|
before anything is pushed — coordinate repo creation with the operator.

|
|
|
|
## Task: Decide credential-brokering ownership for rein-openweights
|
|
|
|
Resolve the open question from ADR-001: does glas-harness broker the
|
|
OpenRouter/llm-connect credential the same way it will broker sand-boxer
|
|
sandbox handles, or does rein-openweights acquire it directly (OpenBao/
|
|
ops-warden) the way rein-aharness does today? Record as an ADR addendum
|
|
before T05 lands, not after.
