A broadcast of a replay: the camera on the action and two commentators — a play-by-play caster and an analyst — written and voiced by the scmjs.dev server. Offered when the scmjs.dev plugin is signed in to an account the server gives casts to (admin only for now) and the replay has been analysed. Stacked on #8 (Economy + Tech); merge that first and this retargets to main.

What it is

• Facts (cast.ts, pure, tested): the whole game as stretches — the quiet parts played fast, the key fights at 1×, no cuts — or the key moments only; for each stretch, timed facts in seconds on screen: supply-counted openings, each player's economy / buildings / upgrades / whole army, supply blocks, and key fights blow by blow (what fell every 1.5 s and what killed it, firsts, the heaviest exchange, where the fight moves). Cards: each research (from its real start, by the game's tables) and the first of each unit and building, tagged in the facts.
• Schedule: one timeline for the whole cast; lines placed after the one before, dropped when they'd come too late for their priority; the last frame held for the sign-off.
• Reel (castplay.ts): plays on the replay's own clock, changes speed at each stretch (cuts only in Key moments), starts each voice at its frame, follows the person's pause and ends on a jump elsewhere. Every line is brought to one loudness (BS.1770-gated, −18), so the two voices match.

Making and watching

• Cast window (one Cast… button on the strip): format, banter, voiced or captions only, cards, notes for the commentators, and the likely length, cost and time to make. Making shows each step live — planning, writing (part and lines as the script streams in), voicing (in batches of twelve), timing — with a clock and the storyline's first sentence (the rest would spoil it). The window can be closed; the strip says when it's ready.
• Kept casts (castmake.ts): IndexedDB, keyed by the replay file's SHA-256 + options, with the voices — watching again needs no server. Reopening the replay offers its newest cast as Watch cast (with Cast… beside it). Asks the browser to keep the storage; past 30 casts or 300 MB the ones watched longest ago go.
• Captions and cards over the game (icon, player, name, progress bar while it's made); no legend under the captions.
• Cinematic view: while a cast plays in the Game view, the game full screen without the editor — a broadcast bar (names, races, supply, workers, army, clock, map), a title card, a key-fight banner, the winner at the end, larger captions, Pause / Leave on pointer move. Needs the Game view.

Tested

• 115 tests (cast facts, segments, schedule, cards, loudness, stream reading, batches, estimate, eviction, Korean catalogue).
• In the editor, headless: a real cast (Opus 5.5 + ElevenLabs via a local ai-server) — 4× opening, 1× fights on time, voices at their frames, loudness gains applied, pause/resume, cards on screen, no errors. The window, progress, kept casts across a reload, and the cinematic view were driven against a stand-in server and a stand-in engine view.

Needs

• scm-js/ai-server#1 (casts, /v1/speech) deployed with the ElevenLabs settings.
• Optional: Account: a Replay casts line in the Status table (1.37.0) plugin-scmjs-dev#2 for the Account window's Replay casts line.
