 ### Changed
 
-- Replaced the hourly Jules issue handoff with a bounded OpenCode commercial builder using `NVIDIA_NIM_API_KEY` through OpenCode's built-in NVIDIA provider.
+- Replaced the direct-provider hourly builder path with a bounded OpenCode commercial builder routed through the organization-owned contextual-orchestrator `orchestrator/free` gateway. Provider credentials remain bootstrap-only sidecar inputs; the model process receives only an ephemeral gateway token.
 - Generate the model-authoritative task from the reviewed default-branch registry, treat GitHub issue prose as untrusted, and fail closed on marker, title, identity, or credential mismatches.
 - Preserve the independent review-agent credential and approval path while keeping the development agent PR-first, single-flight, test-first, and prohibited from merging or releasing its own work.

+OpenCode uses the organization-owned contextual-orchestrator gateway with the fail-closed `orchestrator/free` pool. The workflow passes any available `BYTEZ_API_KEY`, `NVIDIA_NIM_API_KEY`, `NVIDIA_NIM_API_KEY_SUB`, `OPENROUTER_API_KEY`, and `OPENAI_API_KEY` only to the trusted sidecar bootstrap step; OpenCode receives an ephemeral loopback gateway token, never a provider credential. The development agent must create exactly one pull request targeting `develop`. It must not choose a provider, direct endpoint, hardcoded model, or paid fallback, and it must not merge, approve, tag, publish, release, change branch protection, or alter the independent review-agent credential path.
 
-The non-cancelling single-flight job has a 170-minute execution budget. This allows a two-hour implementation plus setup and verification while remaining below GitHub's hosted-runner and workflow-syntax limits. Hourly cron events that arrive during an active pass are serialized by the same concurrency group; they do not create parallel product slices or cancel the current agent.
+The central sidecar is expected to remove provider bootstrap variables after registering them into its process-local credential store. The immutable central revision currently pinned by this change has not yet demonstrated that process-environment scrub; `ContextualWisdomLab/.github#1742` owns the executable RED/GREEN repair. The consumer must not merge until an immutable repaired central pin is available and adopted.
+
+The workflow uses a non-cancelling single-flight concurrency group. Hourly or manual runs that arrive while a pass is active are serialized rather than terminating the in-flight OpenCode reasoning or tool-execution slice. The repository does not configure `timeout-minutes` for this model-backed job. User cancellation, provider termination, hosted-runner/platform limits, and administrative termination remain distinct stop conditions instead of being conflated with an application model timeout.
+
+Before model execution, the workflow verifies the actual pinned OpenCode executable together with the sidecar exports, bearer-file loader contract, authenticated numeric-loopback gateway, and OpenAI-compatible `GET /v1/models` response. It then records a SHA-256 receipt for the gateway bearer. The post-model disclosure check does not source control-plane shell or receive raw provider secret expressions; it first verifies that the bearer file still matches the trusted pre-model receipt.
 
 ## Failure recovery

A transient provider, test, GitHub failure, or timeout can leave the validated coordination issue open without creating a pull request.

+The scheduler contract additionally verifies non-cancelling single-flight concurrency, absence of a repository-authored elapsed-time deadline for model execution, provider-secret expression confinement to the trusted sidecar bootstrap, no post-model control-plane loader execution, bearer-file integrity, and an executable pinned-CLI-to-loopback-gateway handoff. The central sidecar process-environment fix tracked in `ContextualWisdomLab/.github#1742` is an additional immutable dependency gate for this change.

-OpenCode uses its built-in `nvidia` provider. GitHub Actions maps the organization secret `NVIDIA_NIM_API_KEY` to the provider variable `NVIDIA_API_KEY` only for the credential preflight and the pinned OpenCode action.
+OpenCode uses the organization-owned contextual-orchestrator gateway. GitHub Actions gives the sidecar any available `BYTEZ_API_KEY`, `NVIDIA_NIM_API_KEY`, `NVIDIA_NIM_API_KEY_SUB`, `OPENROUTER_API_KEY`, and `OPENAI_API_KEY` only at the trusted sidecar bootstrap step. OpenCode receives an ephemeral loopback `CONTEXTUAL_ORCHESTRATOR_TOKEN`, never a provider credential.
+
+The central sidecar is expected to copy provider credentials into its process-local credential store and scrub the bootstrap variables before model-controlled work can run. The immutable pin used by this change does not yet prove that scrub: `ContextualWisdomLab/.github#1742` tracks the owner-side RED/GREEN repair. This consumer is not merge-ready until that defect is fixed in an immutable central revision and this workflow bumps to the repaired pin.

-The workflow has one non-cancelling concurrency group, so a later hourly event cannot terminate an active commercial slice. The job timeout is **170 minutes**. This permits a two-hour implementation plus checkout, dependency setup, tests, documentation, and pull-request publication while remaining well below GitHub's six-hour hosted-runner execution ceiling and the workflow-syntax maximum of 360 minutes.
+The workflow has one non-cancelling single-flight concurrency group. If a run is still active when the next hourly event arrives, GitHub serializes the later run instead of terminating the active OpenCode reasoning or tool-execution slice. The repository does not impose a `timeout-minutes` deadline on the model-backed job; user cancellation, provider termination, platform limits, and explicit administrative termination remain distinct external stop conditions.
 
-Because the schedule fires hourly, one 170-minute pass may span more than one later cron event. Those later events remain serialized by the same concurrency group rather than creating parallel implementation branches. If a run reaches the reviewed timeout without producing a pull request, GitHub cancels the job, the coordination issue remains open, and a later pass can reselect it only after the active run has ended and the PR queue is still empty. The job-scoped `GITHUB_TOKEN` remains valid only for the job lifetime and is not persisted by checkout.
+Before model execution, `scripts/ci/verify_commercial_gateway_handoff.py` verifies the installed OpenCode version and performs an authenticated `GET /v1/models` against the exported numeric-loopback gateway URL using the sidecar bearer file. Redirects, remote hosts, malformed bearer files, CLI-version drift, invalid JSON, and empty model catalogs fail closed. This is a bounded control-plane handshake, not model inference, so its transport timeout does not terminate reasoning work.
+
+The workflow then records a SHA-256 digest of the gateway bearer before model execution. The post-model disclosure check does not source control-plane shell or reacquire provider secrets; it first proves the bearer file still matches that trusted digest, then scans the result for the gateway bearer. This prevents model-controlled mutation of the loader or bearer file from being treated as trustworthy post-model evidence.
