v1.93.37.0 Price Claude Haiku 5.5, GPT-6 Luna and Gemini 4 Argon for eval planning, and name the GPT-6 tiers in the Codex docs (#3732)

* pricing: rows for claude-haiku-5-5, gpt-6-luna and gemini-4-argon (#3640)

* docs(hosts): gpt-6.1-sol is the default eval tier, not the outside-voice default

* test(autoplan): use a model id with no price row for the unpriced-spend-cap case (claude-haiku-5-5 is priced now)

 # Changelog
 
+## [1.93.37.0] - 2026-11-03
+
+**Eval planning prices Claude Haiku 5.5, GPT-6 Luna and Gemini 4 Argon, and the Codex docs name the current OpenAI tiers (#3640, #2943).** Before, `gstack-eval-plan arms --arms claude-haiku-5-5` stopped with EVAL_PRICE_MISSING because `lib/pricing.ts` had no row for it. docs/hosts.md and the /codex example still named gpt-5.6-sol as the current Sol model.
+
+### Added
+- **Price rows** for `claude-haiku-5-5` ($0.10 / $0.50, cached $0.01, standard tier up to 100,000 tokens), `gpt-6-luna` ($0.10 / $0.50, cached $0.01) and `gemini-4-argon` ($4.00 / $20.00, cached $0.20). Each row cites its provider page. Argon uses the rates that start on 2026-12-01, so estimates never come in low after that date. A repository's model-policy document that names one of these models now gets it as an eval arm.
+
+### Changed
+- **docs/hosts.md and /codex** name `gpt-6-astra`, `gpt-6.1-sol` and `gpt-6-luna` as the current tiers. They also say the bounded-scope overlay still applies only to `gpt-5.6-sol` until it has its own eval.
+
+Thanks to @exGeni (#3640) and @DanCanadian (#2943) for the reports. The TypeSafe Jev rows from #3640 are not included, because a $0 output price breaks the price table's rule that every row has an output price.
+
 ## [1.93.36.0] - 2026-11-03
 
 - **/autoplan R65 defaults: no review for bug fixes, one lean review for features.** `gstack-autoplan next --kind fix` prints `AUTOPLAN: not needed (bug fix; R65)` and `status=skipped run=-` and writes nothing; the PR still needs the bug's proof. `--kind feature`, now the default for an unattended Capy run, runs the eng phase alone with one native reviewer whose brief merges the CEO and Eng lenses (Design and DX only when scope detects them), reads the draft code (a diff against `--base`, hashed into the snapshot, or an honest `DRAFT: none`), always asks "Any outside terms, licences or rights involved?", and has no outside voice, one round, one gate revision and no carry check. The reviewer's result must name the draft hash on its `DRAFT:` line. A failed git command reads `DRAFT: none (draft capture failed: …)`, untracked files named like secrets stay out of the draft, the `DRAFT:` line names the checkout it diffed, and a draft over 100,000 bytes is still inlined, cut there and marked. `run` stays the full run unless `--kind feature` asks for the lean one, `run --kind fix` skips like `next`, and `--kind fix --json` prints one skipped object. `--full` brings back every phase and voice; off Capy and in interactive sessions nothing changes. The gate cost line and the owner brief say a lean `rec` reopens nothing.
