v2.46.0

Community PR bundle: five contributed fixes and features (#62, #63, #64, #65, #66), live-validated on Resolve Studio 21.

Fixed

• Timeline marker frames are now correctly relative to the timeline start (#66). Timecode params and the playhead default rebase by GetStartFrame(), so markers on hour-start timelines land where the Resolve UI shows them instead of an hour past the end of the timeline. Raw frame params pass through unchanged and are documented as relative-to-start. Contact sheets and marker thumbnail review rebase the other way, with a guard so legacy absolute-stored markers still sample the intended frame.
• Project lint no longer flags audio-only timelines as empty (#62). Live lint state reports per-type video_item_count / audio_item_count / subtitle_item_count.

Added

• media_pool.check_proxy_media_compatibility (#63): ffprobe-vs-source signature diagnostics covering resolution, fps, frame count, sample rate, and expected codec/profile. Same-aspect downscales count as compatible — half-res proxies are the normal proxy workflow.
• Readback verification envelopes (verified_operation) around media_pool.link_proxy_checked (#63) and media_pool.append_to_timeline (#64): preflight, execution, post-state readback, verification status, and a journal event. link_proxy_checked gains check_compatibility / require_compatible guards that refuse incompatible proxies before linking (PROXY_INCOMPATIBLE).
• bins in declarative project specs (#65): missing media-pool bin paths plan as ensure actions and are created idempotently; existing bins are noops. Bin paths normalize to the Master/ prefix so unprefixed spec bins converge instead of reporting perpetual drift.

Validation

• Full offline unit suite green: 1153 passed, 0 failed (plus 207 subtests).
• Release static checks green: import probe, API parity audit, undefined-name / action-list / panel-docs drift guards, npm pack.
• Live Resolve Studio 21.0.0.47 validation on disposable projects with synthetic media:
  • tests/live_marker_validation.py passed on an hour-start timeline (raw frame 12 → 12, playhead → 120, timecode +2s → 48; all markers within the visible timeline).
  • Proxy link readback: half-res ProRes proxy linked with verification_status: readback_verified (Proxy Media Path confirmed via GetClipProperty), zero contradictions; mismatched square/30fps file correctly refused by require_compatible before linking.
