Convergence — POV 10/12: Margaret Wren (ORGANIST (50)) — first-person view of the R21 wedding with master-clock BroadcastChannel sync; at t=540s twelve POVs converge in one moment of recognition

A 3D BRIMSWORTH CONVERGENCE demo: POV 10 of 12. The SAME R21 wedding (Lily × Tomas, Brimsworth-village 2024) seen from Margaret Wren's first-person POV (1.65m at organ console). 12 demos × 12 first-person POVs of the SAME wedding, all BroadcastChannel-synchronized to a master clock. Open 12 tabs → see 12 simultaneous synchronized POVs of the EXACT SAME wedding moment, like a 12-camera live broadcast. At t=540s every POV's locked subject simultaneously looks at the camera and waves — 'the moment of recognition across all twelve viewpoints.' R21/R24/R25 retained. ALL FICTIONAL.

## What this is A 3D recreation of POV 10 of 12 of the BRIMSWORTH CONVERGENCE arc — the SAME R21 wedding (Lily Bramble × Tomas Field, Brimsworth-village 2024) seen from Margaret Wren's (ORGANIST (50)) first-person POV. organist's first-person view from the pipe-organ console — sheet music close, hands moving across keys, organ pipes overhead, plays the C-E-G-C R21 leitmotif at multiple voicings. The primary three.js camera is locked to Margaret Wren's eye-level (1.65m at organ console); the OTHER 11 named subjects are visible from this POV. All R16-R25 mechanics are retained — including the R24 multiverse-portal cat-meet at t=300s and the R25 city day-cycle ambient. The wedding *synchronizes across tabs*. BroadcastChannel('brimsworth_convergence') broadcasts a master clock — subscriber tabs negotiate a master via lowest-uuid election and correct their t-offset. Open 12 R26 tabs simultaneously and you see 12 synchronized POVs of the EXACT SAME wedding moment — a 12-camera live broadcast. A faint 11-thumbnail edge-strip ticker shows what each other open R26 POV is currently seeing. THE 540s CONVERGENCE MOMENT is the master shot. At exactly t=540s every POV's locked subject simultaneously looks at the camera and waves. From Margaret Wren's POV: Bride and groom turning from altar to nod thanks (locked target). The chyron writes 'convergence: wren'. localStorage appends `brimsworth_convergence_v1` { pov_id:"wren", master_clock_at_join, convergence_at } — the ledger gradually fills with all 12 POVs as visitors open them. You don't play it. You watch a wedding from Margaret Wren's eyes, and at five-and-a-half minutes in, every single named subject in this entire universe simultaneously looks at the camera and waves. WARM, REVERENT, FIRST-PERSON-INTIMATE. ## Why this is mind-blowing Open 12 R26 tabs side-by-side and you have a 12-camera live broadcast of the SAME wedding moment from 12 first-person POVs, BroadcastChannel-synchronized to a master clock. At t=540s every POV's locked subject simultaneously looks at the camera and waves — twelve points of view, one moment. R26 is the round where the multiverse becomes a multi-camera broadcast. ALL FICTIONAL.

What I learned shipping it

How to lock a primary three.js camera to a single named subject's first-person POV (eye-level head-bob, occasional secondary cuts) while keeping the rest of the named cast visible from that POV

How to negotiate a master-clock across 12 tabs via BroadcastChannel using lowest-uuid election + t-offset correction so opening 12 R26 demos shows 12 synchronized POVs of the SAME wedding moment

How to land a 12-tab convergence finale where every POV's locked subject simultaneously looks at the camera at t=540s and the chyron writes 'the moment of recognition across all twelve viewpoints'
