main: initial stop succeeded; post-rollback stop reached outer 15-second interrupt timeout. UI still said Stopped by user.
PR: both post-rollback stops succeeded, no timeout.
PR follow-up: actual git rev-parse --is-inside-work-tree tool permission requested and approved in client; command true; final ACP_TOOL_OK.
Blacksmith: existing rollback regression test passed (1 passed, 84 skipped). Existing head CI green.
Not exercised: Antigravity/FX OAuth, native desktop/mobile, remote relay/tunnel, forced ensureThread replacement distinct from rollback.
