ci(relayflows): add isolated dev proof lane

[miyaontherelay]

Summary

• add a manual dev-canary target to the existing RelayFlow PR proof dispatcher
• execute the canary through a reusable workflow protected by the relayflow-dev-proof GitHub environment
• use unique dev-only Cloud configuration and reject any URL outside https://dev.agentrelay.com
• keep the canary unable to publish the production RelayFlow PR proof commit status

Required GitHub environment configuration:

• Environment: relayflow-dev-proof
• Environment variable: RELAYFLOW_DEV_PROOF_CLOUD_API_URL=https://dev.agentrelay.com/cloud
• Environment secret: RELAYFLOW_DEV_PROOF_CLOUD_API_KEY=<dedicated dev workflow-invoke token>

The dev token must be minted in dev for the dev Cloud workspace. It must not contain or reuse the production credential.

Test Plan

• Tests added/updated
• actionlint .github/workflows/relayflow-pr-proof.yml .github/workflows/_relayflow-pr-proof-dev.yml
• git diff --check
• static dev-lane security contract assertion
• manual dev dispatch after environment credential provisioning

RelayFlow Proof

• Change type: non-functional
• RelayFlow case: n/a

Screenshots

Not applicable.

📝 Walkthrough

Walkthrough

The PR adds a manual dev-canary target for RelayFlow PR proofs. The target invokes a reusable workflow from main, validates development settings, runs an isolated proof against dev.agentrelay.com, and uploads logs.

Changes

RelayFlow development canary

Layer / File(s)	Summary
Canary target routing .github/workflows/relayflow-pr-proof.yml	Manual runs select production or dev-canary. Development runs use separate concurrency, skip the production dispatcher, and call the reusable workflow from main.
Development canary execution .github/workflows/_relayflow-pr-proof-dev.yml	The reusable workflow uses restricted permissions and a dedicated environment. It prepares and validates PR proof input, checks development Cloud credentials and origin, runs the isolated proof, and uploads logs.
Canary contract validation tests/fixtures/pr-proof-contract.test.ts	The contract test verifies protected main routing, development credentials, environment and origin isolation, checkout behavior, and exclusion of production permissions and secrets.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 383eb

The new manual dev-canary lane can run against a workflow revision different from the selected PR head, which could produce a canary result for the wrong change. The PR is mergeable with explicit owner awareness and follow-up to validate that the workflow ref matches the intended PR revision.

A rabbit checks the canary gate
Dev proofs run while logs await
Main holds the dispatcher key
Dev credentials keep paths free
The artifact hops safely home

Full details: Description check

Explanation

The description includes the required Summary, Test Plan, RelayFlow Proof, and Screenshots sections. It documents the dev environment configuration, completed validation, and the pending manual dispatch clearly. The non-functional and n/a proof values are appropriate because runtime behavior is unchanged.

Full details: Docstring Coverage

Explanation

No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff. Analyzed 0 functions across 1 files. (2 skipped: 2 unsupported.)
