- Always emit `model_provider = "custom"` from deep link, UniversalProvider, and the universal form modal so future writes share one stable routing key.
- Add `codex_provider_template_v1` local migration that rewrites legacy keys (aihubmix/ccswitch/...) under `[model_providers.custom]`, updates profile refs, and backs up the original settings_config under `~/.cc-switch/backups/<timestamp>/providers/`.
- Tighten history migration source detection to a whitelist plus `[model_providers.<id>]` existence check so user-authored keys are never rewritten in jsonl/state DB.
- Encode deep link name/model/endpoint through `toml_edit::Value` so display names containing quotes or backslashes no longer break the generated config.toml.
- Stabilize provider settings backup filename hash with Sha256 (was process-random SipHash).
Codex CLI filters conversations by model_provider — after normalizing
all third-party providers to "custom", old sessions with their original
provider IDs become invisible. This migration rewrites JSONL session
files and state_5.sqlite threads to use the unified ID.
Uses a three-tier trust model for source ID collection:
- Known legacy preset whitelist (46 IDs, case-insensitive)
- cc-switch-created custom providers (identified by created_at)
- User-maintained custom providers are explicitly skipped
Adds scanned_history_files flag to prevent stale v1 markers from
blocking re-runs with the improved source ID collection logic.
Codex filters resume history by `model_provider`, so switching between
provider-specific ids like `rightcode` and `aihubmix` made past sessions
appear to vanish. Collapse all third-party providers into a single
stable bucket so cross-switch history stays visible.
- Normalize live `model_provider` to "custom" on every Codex write
(reserved built-in ids like openai/ollama are preserved).
- Add device-level one-shot migration that rewrites historical JSONL
session files and the `state_5.sqlite` threads table from legacy
provider ids into the "custom" bucket. Backs up originals under
`~/.cc-switch/backups/codex-history-provider-migration-v1/` and uses
the SQLite Backup API for the state DB.
- Record completion in `settings.json` under `localMigrations` so the
migration is strictly idempotent across launches.
- Update Codex provider preset templates to emit `model_provider = "custom"`
out of the box.
