Preserve manual-token defaults across explicit profile refreshes and selective logout while keeping legacy marker behavior compatible.
Make profile login, refresh, switch, and logout writes rollback-safe; reject unsupported future profile versions before remote side effects; and prevent cross-profile token fallback.
Forward token overrides through usage recording, use the newly authenticated identity for post-login authorization, distinguish unavailable profile state, and propagate Windows registry deletion failures.
Store DingTalk credentials in corpId:userId identity slots while retaining organization and legacy mirrors for forward compatibility.
Resolve organization, account, friendly-name, current, previous, and deletion selectors without silently choosing among ambiguous accounts.
Make identity tokens the source of truth, serialize migration and refresh reads, reject unsafe mirror recovery, and sweep orphan token entries during reset.
Persist token source and client ID for exact remote revocation, require user identity before first-login persistence, and add cross-platform regression coverage for migration, deletion, refresh, and keychain failures.
In sandboxed macOS runtimes (e.g. Codex App), `security` / Keychain APIs
are blocked, so `keyring.Get`/`Set` for the DEK fails on every token
read/write. Add an opt-in env var that switches the macOS implementation
to the same file-based DEK scheme already used on Linux. Default
behavior is unchanged.
- Extract shared `fileDEK(service)` into `file_dek.go` (darwin || linux)
- Linux `getDEK` now delegates to `fileDEK`
- Darwin `getDEK` short-circuits to `fileDEK` when DWS_DISABLE_KEYCHAIN=1
- Document the tradeoff in reference.md (DEK and ciphertext co-located)
- Add darwin-only tests covering fallback path + overwrite
