- Replace tidwall/gjson and tidwall/sjson with github.com/MoeForge/moego/ojson
and encoding/base64 with github.com/MoeForge/moego/base64 across the main
module and examples
- Introduce cross-method *ojson.Doc request rewriting pipelines across
thinking, signature, client/codex, runtime/executor/helps, pluginhost, and
all provider executors with FinalizePayloadDoc as the final semantic barrier
- Convert all consecutive JSON mutations (>= 2 Set/SetRaw/Delete operations)
to batch edits on ojson.Doc
- Upgrade read-only byte paths to ojson.GetBytesNoCopy,
ojson.GetManyBytesNoCopy, and util.ParseGJSONBytesNoCopy with explicit
strings.Clone ownership protection across streaming and persistent state
- Use base64.StdEncoding.ValidateString for zero-allocation signature checks
and base64.EncodeDataURL for single-allocation data URL construction
- Set `tool_mode` to `"direct"` and disable `use_responses_lite` and `supports_reasoning_effort_updates` when normalizing Codex catalog entries for non-template models and non-Codex or mixed-provider routes.
- Reset `tool_mode`, `use_responses_lite`, and `supports_reasoning_effort_updates` when synthesizing a fallback `gpt-5.5` baseline template in `fetch_codex_models`.
Closes: #6769
Load codex_client_models.json like models.json with validation, revisioned
handler reloads, CI bake, and Home-aware updater gates so list IDs still
come from Home while templates can refresh on the edge.
