Summary

Registers GPT-6 Astra as an optional Codex family, so a model sheet can name codex:gpt-6-astra@<effort>. On main the registry resolves it as unregistered.

 FAMILIES
   luna   codex:gpt-6-luna    low..max     default max
+  astra  codex:gpt-6-astra   low..ultra   default max   optional, upstream null
 RELEASED_PAIRS
   ...
   claude:claude-haiku-5-5
+  codex:gpt-6-astra

The efforts come from the CLI. Codex CLI 0.164.0 codex debug models lists gpt-6-astra with low medium high xhigh max ultra (Luna lists no ultra). The default is max, as for Sol and Luna. The pair is appended because the released-pair list is append-only. Codex families generate no Claude agents, and render.ts --write changed only the catalog row. docs/reference.md now says ultra is offered on Sol and Astra, and CHANGES.md gets an Unreleased entry. Default roles and panels are unchanged.

Evidence

• Before: on main, resolveModel("codex", "gpt-6-astra") returns {"kind":"unregistered"}.
  After: it returns current with family astra. registry.test.ts asserts that Astra resolves to astra at max by default, and that @ultra reaches Codex as model_reasoning_effort="ultra".
• One read-only probe through this branch's pstack-runner (--parent claude --provider codex --model gpt-6-astra --effort high --mode read-only) exited 0 in 17.9 s. The receipt reads status: complete, modelEvidence: pinned-argv, error: null. The model replied: defaultEffort: "max"; efforts: ["low", "medium", "high", "xhigh", "max", "ultra"]. The receipt stays local and private: open-pstack-astra-probe/receipt.json.
• Gate, run locally under the pinned Bun 1.4.0: bun run test 506 pass, 0 fail. bun run typecheck passes. claude plugin validate plugins/pstack passes. bun run static passes its JSON and skill checks, and its verifier suite runs 200 pass, 1 fail. The failure is publisher request boundaries > a manifest is version-only when only its version strings changed since the merge base, which hits Bun's 5 s default timeout on this machine. It fails the same way on a clean origin/main worktree, and passes on both trees in about 9 s under --timeout 30000.

Merge Danger

Door: two-way

One new family row and one new released pair. Reverting removes the row, and a sheet that names Astra resolves as unregistered again, as it does on main today.

Blast Radius: opt-in

No role default uses Astra. Only a sheet that names it changes behavior.

Verification

• Bun tests, strict typecheck, static invariants, and plugin validation pass (static's one local timeout is noted above).
• The exact candidate is installed in every affected harness.
• The changed behavior passes from each real user surface.
• The live-gate status on the final head links the evidence comment (installed version, surface, action, observed result).

[Medium impact] The code changes appear safe to merge once the required exact-head live gate passes.

Summary

Adds GPT-6 Astra as an optional Codex family with efforts from low through ultra and a default of max.

• Model sheets can now select GPT-6 Astra through Codex.

Merged as #267, with you as the commit author. It ships in Open Pstack 1.17.0. Thanks for the clear evidence.

#251: register GPT-6 Astra as an optional Codex family (fork PR by shookya)

Ported as PR #267 with shookya as commit author; #267's keyword closed the fork PR, which got a thank-you. The registry row matches codex debug models on Codex CLI 0.166.0 (low to ultra, default max), no role changed. Live proof was the catalog feature in both harnesses on ceb2a8a and on the queue-created head 4926185; no Astra model ran through the runner on the port (the fork's own probe ran on Codex 0.164.0). Reader correction. Shipped in 1.17.0.
