Browser discovery and later CDP failures previously lost launch evidence when their private fixture was removed. Retain failed private fixtures locally and export fixed-shape launch observations. Startup-only stderr is capped at 65,536 bytes; stderr after a page visit is withheld from public artifacts. CI uploads only two explicitly allowed files.
The launch record distinguishes settled status, signal, observation before cleanup, cleanup request and port-read outcomes. Post-renewal liveness has its own transport label. Original startup polling, CDP deadlines, execution completion guard, renewal interval and process ownership remain unchanged.
This diagnostic change addresses evidence collection for #64 and #44. It does not establish those original failure causes. The combined main-target diff includes #69 runtime cold-build initialization and cleanup qualification.
Validation:
- Final focused regression: 19 passed, two actual-browser cases skipped, zero failed, 166 assertions. Pickier and application/runtime types passed. Both independent review axes are clean.
- Actual macOS workspace and execution browser attempts failed with observed child exit 0 before cleanup. Both failed private profiles and original logs remain retained. The reporting path exported launch metadata and withheld post-page stderr. Neither macOS browser scenario passed.
