v1.8.2 — robust OUTPUT_FOLDER parse + scene threshold 0.04

Changed

• Scene-detection default threshold raised 0.025 → 0.04. On talking-head and slide-heavy videos the old default tripped on minor frame changes and often hit the 50-capture cap (then thinned); 0.04 yields fewer, more meaningful captures by default. Tune per video with --screenshots scenes=<0..1> (lower = more).

Fixed

• Robust OUTPUT_FOLDER: parsing. When a worker subagent returns, the harness can append an agentId: <hex> trailer directly onto the trailing OUTPUT_FOLDER: line with no separating newline (e.g. …_my-slugagentId: a2ba…). The orchestrator now extracts the folder by cutting at the first whitespace or the literal agentId substring instead of taking the raw last line, so the trailer can no longer be folded into the saved folder/file name. Documented in SKILL.md Step 3, mirrored in the CLAUDE.md sentinel registry, and covered by a new static contract test.
