dsh-codex: OpenAI Codex Subscription Provider Foundation

Foundation contract

This is a cold, source-specific foundation, not an operational procedure. It is historical, revision-pinned evidence rather than timeless guidance. Current project source, tests, requirements, and runtime behavior outrank this projection and decide what ships.

Provenance and revision

Source record: dsh-codex; portable upstream identity, license, coverage caveats, and retrieval history are preserved in the index.
Recorded revision: main@e3e54e206f7c829503c7e6eed378643ba0416792.
Full provenance, coverage caveats, boundaries, and preserved evidence: references/index.md.

Topic map

Representative topics: Provider auth adapter; Browser challenge lifecycle; Cancellation and teardown; Status recovery; Trusted request gate; Trusted origin store; Auth route contract; CLI auth modes.
Scope and retrieval questions: references/index.md#use-this-for.
Complete capsule chooser: references/index.md#load-the-matching-source-dump.
Detailed grouped map: references/index.md#capsule-map.
Source limitations and portability boundaries: references/index.md#boundaries.

Retrieval

Open the index, choose one capsule matching the active question, and load only that capsule. Revalidate its cited source and revision before relying on it. Do not bulk-load the inventory, treat historical claims as current truth, or apply this foundation as a procedure.
