- Introduced GPC OTP channel selection (WhatsApp/SMS) in the sidepanel.
- Added local SMS helper toggle and URL input for macOS users.
- Implemented normalization functions for OTP channel and local SMS URL.
- Updated settings payload to include new GPC helper configurations.
- Enhanced Plus checkout process to utilize local SMS helper for OTP retrieval.
- Added tests for GPC SMS helper script and its integration in the checkout flow.
- Updated documentation to reflect new GPC helper features and configurations.
This keeps the existing CPA, SUB2API, and contribution flows intact
while introducing codex2api as a separate source that plugs into
Step 7 and Step 10 through backend APIs instead of page DOM.
The sidepanel now exposes codex2api settings, preserves the built-in
local default through placeholder-only UI, and accepts user-provided
public admin URLs. Step 7 now treats missing or invalid management
secrets as terminal config errors so the flow stops instead of retrying
needlessly.
Constraint: New source must be additive and must not break existing CPA/SUB2API/contribution paths
Rejected: Drive codex2api through admin page button clicks | too brittle against frontend DOM changes
Rejected: Reuse contribution mode as a source surface | violates existing panelMode/runtime-mode boundary
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep codex2api on the protocol path unless its API becomes insufficient; do not add a panel content script without proving the protocol path cannot work
Tested: npm test; targeted codex2api/auth retry loops repeated 40 times; full suite repeated 5 times
Not-tested: Real browser run against a live codex2api instance with a real Admin Secret and OpenAI authorization
Expose a configurable default proxy for SUB2API, resolve the proxy once,
persist the proxy_id in state, and reuse it across auth URL generation,
code exchange, and account creation so one OAuth flow stays on one proxy.
Constraint: Upstream GitHub permission is READ, so publication must use a fork PR
Rejected: Push to origin | current GitHub viewer permission does not allow upstream branch publication
Rejected: Resolve proxy independently in later steps | could drift from the proxy chosen at auth URL generation
Confidence: high
Scope-risk: moderate
Reversibility: clean
Tested: npm test passed 183/183
Not-tested: Manual browser extension flow against a live SUB2API deployment
