Ordering policy
Broadcast date is the default axis. Explicit numbered events override same-date technical tie-breaks. Narrative dates remain absent unless episode evidence supports them.
Primary evidence path
Universe Watch Order
Original broadcast order with explicit crossover-part sequencing. Dates describe release history, not unsupported in-story chronology.
Concurrent release lanes
The Lab Braid
Thirty-nine seasons mapped on one date axis. The overview shows overlap; the underlying watch path remains the episode-level authority.
Select a season block to open its case file.Diamonds mark crossover and continuation events.
Lab-by-lab inventory
Series Case Files
Five complete scripted catalogs plus the exact optional external episode needed to finish a CSI case.
Cases that cross boundaries
Cross-Jurisdiction
Backdoor pilots, multi-city cases, outside-program bridges, the Cyber handoff, the finale, and the return to Las Vegas.
Continuity under oath
Labs & People
Verified series launches, character transfers, returning leads, and external connections. Scope labels distinguish a whole-series bridge from one guest episode.
Scope firewall
Without a Trace contributes one required conclusion. Cold Case is represented by the CSI: NY episode containing its character. No external catalog is recursively imported.
Immortality reconciliation
The regular-series subtotal is 836. Paramount’s two-part finale presentation creates two additional core parts grouped under one Immortality story.
Private source of truth
The public page contains normalized display data only. Source snapshots, provenance tables, review queues, and generator scripts remain private.
