Gengchou v2.3.3

Gengchou v2.3.3

v2.3.3 adds explicit, provider-specific permission before Gengchou reads any
local provider credential or starts provider polling.

Changes

• Ask before accessing Claude Code, Codex, or Antigravity credentials. Each
  prompt identifies the credential source, defaults to No, and records the
  user's decision.
• Add a Provider access submenu for granting or revoking each permission at
  any time. Revocation stops credential watches and future polls, invalidates
  in-flight results, and removes that provider's cached usage.
• Keep dynamic authentication refresh working after permission is granted by
  re-reading the original credential file or Windows Credential Manager entry.
  Gengchou does not copy or store provider tokens.
• Keep the detail popup open across focus changes when it is pinned.

Updating

Existing users are asked once for each visible provider because older settings
do not contain a permission decision. Choosing No is remembered and no
credential-backed operation runs for that provider. Permission can be changed
later from the context menu.

No settings or cache migration is otherwise required. Do not update an
installation older than v2.2.4 directly to this release; v2.2.4 remains the
required bridge.
