Role contracts (roles/<role>.json): roleVersion, name bound to filename,
tools ceiling (subset of pi built-ins), network declared (none|api-only|
open; enforced when network policy lands). Strict schema, fail closed -
a non-role document refuses resolution.
mosaic-task.mjs resolve-role: config-free contract validation, emits
MOSAIC_ROLE_TOOLS / MOSAIC_ROLE_NETWORK.
agent.sh: a declared role binds to its contract. Missing/invalid contract
refuses the launch (exit 2, names the role - the under-equipped-seat
failure mode, mirroring M17 skills). Effective tools = ceiling ∩ requested
(CLI --tools or agent.json caps); no request -> ceiling stands; narrowing
and tool-free outcomes loud on stderr. Adapters unchanged; headless M9
chain (mission ∩ task) untouched.
Ships roles/researcher.json (existing seat declares the role; without the
contract the fail-closed gate would refuse its launch).
Task suite 74 -> 88: contract resolution, wrong-kind/name/network/
duplicate/unsupported/missing refusals, ceiling narrowing E2E (mock
adapter), tool-free E2E, missing-contract refusal. Test-authoring
correction recorded in BUILD-LOG (a check that registered on one path
only, caught by count arithmetic).
Suites 24/88/14/17 + verify green.
Owner direction: the repository root holds first-class, bootstrap-required
configuration only. conductor-policy.json is a ROLE contract (the
conductor's authority), one of scores of future role contracts
(agent-policy, coder-policy, ...) - such files get a dedicated home.
- roles/conductor-policy.json (git mv)
- conductor-apply.sh + test-conductor.sh read the new path
- CONDUCTOR.md records the roles/ convention
Closes UX follow-up from owner layout review; no issue (convention change).
