…gg#13094) Import the upstream Claude Opus 5.5 manifest entry and capability profile. Keep the fork-owned manifest source and document the legacy classification overlay. Co-authored-by: Anco <anco@bluebarry.ai> Co-authored-by: Exotic <118054752+extoci@users.noreply.github.com> Co-authored-by: Julius Marminge <51714798+juliusmarminge@users.noreply.github.com> (cherry picked from commit f25a8e4) Upstream-PR: 13094 Upstream-Commit: f25a8e4
Classify Opus 5 as legacy in both the catalog and pre-discovery overlay while keeping its alias for older Claude Code versions. Match upstream Fable 5.1 defaults, profile, version gate, and badge behavior; the earlier fork-specific profile was not a maintained product difference. The Fable manifest values follow upstream PRs 11347 and 12173. This commit does not import the non-manifest changes from PR 11347.

Codex discovers available models from its own app server, but styal's manifest still classifies GPT-5.6 as current. GPT-6-Astra, GPT-6-Sol, and GPT-6-Luna therefore appear under Legacy models even when the installed Codex CLI offers them. New Codex threads also still default to GPT-5.6-Sol. Classify the GPT-6 family as current and prefer GPT-6-Sol for new Codex threads. If Sol is unavailable, prefer GPT-6-Astra, then an available GPT-5.6 model; if none of these are present, keep Codex's own reported default. The GPT-5.6 models remain selectable from the live CLI inventory under Legacy models. Choosing Sol over Astra is a deliberate styal default difference from current upstream. This change is separate from the Claude catalog update in #405 because it affects a different provider. The installed Codex CLI 0.155.1 reported all three GPT-6 models and the GPT-5.6 models in its `model/list` response. In an isolated headless Chrome run, a fresh composer selected GPT-6-Sol with Medium effort, the picker showed the GPT-6 family as current, and GPT-5.6-Sol appeared under Legacy models. Chrome reported no page errors. Focused Codex provider, manifest, and fork ledger tests passed (28 tests), including preference and fallback cases. Contract and server typechecks, ledger validation, and targeted formatting checks passed. Remote update checks were disabled for the updated local run because the fork's published manifest still predates this PR. No authenticated model inference request was sent. | Before | After | | --- | --- | |  |  | | GPT-5.6-Sol selected in the composer |  | --- Written by an agent (Codex, GPT-6). --------- Co-authored-by: Julius Marminge <julius0216@outlook.com> Co-authored-by: Codex <codex@users.noreply.github.com>

Claude Code 2.1.284 ships Claude Sonnet 5.5 and points its `sonnet` alias at it, but styal's Claude model manifest does not list the model, so the Claude picker cannot offer it. Upstream T3 Code has no Sonnet 5.5 support yet. This adds a Sonnet 5.5 manifest entry and profile, following #405 for Opus 5.5: - `claude-sonnet-5-5` is a current model with a NEW badge, shown only for Claude Code 2.1.284 or newer. Older CLIs see the existing "too old for Claude Sonnet 5.5, upgrade to v2.1.284" notice. - The profile follows the model catalog bundled in Claude Code 2.1.284: effort low through max with medium as the default, ultracode (Claude Code offers it on every model with xhigh effort), and ultrathink. There is no fast mode. The context window defaults to 200k with 1M selectable through the `[1m]` suffix, matching Sonnet 5, whose context metadata is identical. - Sonnet 5 moves to Legacy models. It keeps the `sonnet` alias for older Claude Code versions, the way Opus 5 kept `opus`. - `currentModels.claudeAgent` lists Sonnet 5.5 in place of Sonnet 5 for releases that predate catalog discovery. The Claude Code default stays Opus 5.5. ## Validation - I loaded the bundled catalog and resolved models for Claude Code 2.1.283 and 2.1.284. With 2.1.283, Sonnet 5.5 is hidden and the upgrade notice names v2.1.284. With 2.1.284, it appears just ahead of Sonnet 5 and defaults to medium effort. Ultracode is sent to Claude Code as `xhigh`. Choosing 1M resolves to `claude-sonnet-5-5[1m]` with a 1,000,000-token window. `sonnet-5.5` resolves to the new model, and `sonnet` still resolves to Sonnet 5. - Manifest and Claude catalog tests pass (14 tests). - In an isolated web dev server whose Claude provider used the Claude Code 2.1.284 binary from npm, with remote manifest fetches disabled, the picker listed Sonnet 5.5 with a NEW badge in place of Sonnet 5, and Legacy models grew from 8 to 9. Selecting Sonnet 5.5 showed `Medium · 200k`, and its menu offered Low through Max, Ultracode, Ultrathink, and a 200k (default) or 1M context window. - No authenticated inference request was sent to Sonnet 5.5. ## Screenshots Before, on `main`:  After, with Sonnet 5.5 among current Claude models:  Sonnet 5.5 reasoning and context options:  --- Written by an agent (Claude Code, claude-opus-5-5).

…11347) Co-authored-by: maria-rcks <254055478+maria-rcks@users.noreply.github.com> Fork adaptation: Keeps the fork's GPT-6-Sol Codex default with GPT-6-Astra as its first fallback (codex-default-model) and Claude Opus 5.5 as the Claude default from fork #405. Fable 5.1's medium default effort is already present from fork #405, so this takes GPT-6-Astra's medium default effort. (cherry picked from commit 1f73a89) Upstream-PR: 11347

…11347) Co-authored-by: maria-rcks <254055478+maria-rcks@users.noreply.github.com> Fork adaptation: Already present. The fork chooses its own Codex and Claude defaults (codex-default-model: GPT-6.1-Sol, then GPT-6-Sol and GPT-6-Astra; Claude Opus 5.5 from fork #405), fork #405 already gave Fable 5.1 a medium default effort, and fork #543 makes medium the default effort for every Codex model that offers it, which covers GPT-6-Astra. This commit records provenance only. (cherry picked from commit 1f73a89) Upstream-PR: 11347

Current styal installations fetch Claude model data from the fork's
mainmanifest, which does not contain Opus 5.5. Their bundled fallback lacks it too, so the Claude picker cannot show the model despite remote catalog support already being present.Add the Opus 5.5 catalog entry and capability profile from
pingdotgg/t3code#13094. Claude Code 2.1.280 or newer lists it with a NEW badge, medium default effort, and 1M context support. Move Opus 5 into Legacy models while keeping itsopusalias for older Claude Code versions. Align Fable 5.1's effort profile, version gate, and badge with upstreampingdotgg/t3code#11347andpingdotgg/t3code#12173; the fork's separate Fable profile was not an intended maintained difference. Set Opus 5.5 as styal's new Claude Code default, deliberately differing from upstream's Fable 5.1 default. Older CLIs select an available model after version filtering.
