📄 Description

Description

Fixes a process-capture validation race where a resize renderer entry used its exact dispatch time while adjacent PTY output used a normalized time bucket. A resize at 301 ms followed by its SIGWINCH output at bucketed 300 ms preserved causal order but produced decreasing rendered-frame timestamps, so an otherwise successful capture returned a validation error.

Resize renderer entries now use the same elapsed-time normalization helper as PTY frames. Interaction-event dispatch times remain exact; renderer and journal order remain causal and are not sorted or clamped.

The regression uses a 60-second bucket so the old mismatch is deterministic on PTY-capable hosts.

Type of Change

Bug fix
New feature
Breaking change
Documentation-only change
Refactor (no behavior change)

Testing

Unit tests added or updated
npx vitest run tests/processCapture.test.ts
npm run typecheck
npm run lint
Real Hopper smoke test (if applicable)
Browser CDP end-to-end verifier (if applicable)

Real-provider verification is not applicable to the provider-neutral PTY capture path.

Tool Contract Impact

MCP tool schemas changed
CLI behavior changed
Generated product catalog refreshed
Documentation updated

No schema change. Valid resize captures no longer fail when timestamp normalization crosses a bucket boundary.
