CLAUDE_CODE_EFFORT_LEVEL hard-locks effort for the whole session and makes
Claude reject in-session /effort switching (incl. ultracode). Carry effort
as a dedicated payload field instead, injected at spawn as a soft default:
- regular levels (incl. max) -> claude --effort <level>
(the settings effortLevel key is enum([low,medium,high,xhigh]) with
.catch(undefined), so max would be silently dropped there)
- ultracode -> claude --settings '{"ultracode":true}'
(dedicated boolean settings key, rejected by the --effort flag)
Changes:
- add effort enum field to create/quick-start/ralph-loop schemas and thread
it through Session -> CreateSessionOptions/RespawnPaneOptions -> spawn
- buildEffortCliArgs() in session-cli-builder, shared by tmux spawn command
and direct-PTY fallback args
- frontend: buildEnvOverrides() no longer emits CLAUDE_CODE_EFFORT_LEVEL;
validated effort goes into payloads via getEffortSetting()
- settings UI: add Ultracode option to the Thinking Effort dropdown
- legacy migration: Session constructor extracts CLAUDE_CODE_EFFORT_LEVEL
from persisted envOverrides; applyEnvOverrides() unsets the stale tmux
session var so respawned panes are no longer locked
- tests: test/effort-injection.test.ts (13 cases)
