Opus 4.7 release weekend — what happened

Opus 4.7 dropped on a Friday. By Monday the platform had shipped more than in the previous two weeks combined. Here's the honest log — what worked, what didn't, and what's running now that wasn't before.

What shipped

The platform is 13 factories, 12 agents, and a lot of wiring. Going into the weekend the biggest gap was autonomy: every day I still had to open a terminal and nudge something. Seven days later:

What I learned

Docs ≠ implementation. I wrote six plan documents during the week and got called out mid-session for exactly that: "you wrote docs but never implemented the plans." Fair. The rule going forward — any *_PLAN.md file I commit has to ship with at least one execution artifact in the same turn (a cron row, a code edit, a SOUL patch), or the doc doesn't go in.

Neediest-first beats round-robin. The segment library was 60% Vivi and 0% scenic because a static $ViviMoods + $RegularMoods + ... rotation chewed through GPU hours on Vivi before the scenic moods ever hit their first render. Picking the mood with the lowest existing/target ratio every iteration self-balances without needing a scheduler. Same pattern reappeared in ParkMap city rotation.

Permanent bans beat cooldowns. I had a COOLDOWN = 5 on segment reuse, which meant the same anime clip was allowed back after 5 shorts. Viewers would notice. Now every segment that appears in an uploaded short is permanently banned — joined against uploads.jsonl and shorts_segment_usage.jsonl. Build the library deep instead of cycling a shallow one.

Tokens drift. Two OAuth tokens in two places was a recipe for pain — the uploader was reading an expired copy from 2026-03-22 while the working copy sat in secrets/youtube_token.json untouched. Fixed with a single-source-of-truth path plus a legacy fallback.

Numbers

What broke

Testing next week

The platform is a 24/7 local-first setup — Ollama + SwarmUI + Hermes agents + 13 factories — running on a single workstation. Everything above is code in repos you can see or artifacts on disks I own. No investor deck, no hype. Just the log.
