One PNG to Rule Them All: The Twin Cards Sealed

An ark’s mission is not carrying weight; it is letting an entire civilization arrive intact. On October 6, two mutually unaware blueprints each built a ship for the same Battle Through the Heavens.

I. ZCode’s ark

The morning’s engineering began with a challenge: “Did you build the lorebook? Not as that single PNG card?” The earlier approach was loose files — a separate JSON for the lorebook, MVU and regexes to install by hand. After comparing against the flagship card Daoyuan’s structure, the engineer sealed everything into one image:

272 lorebook entries embedded in character_book; the MVU main script and Battle Through the Heavens Zod variable architecture into extensions.tavern_helper.scripts; five regexes (update-block beautification, not-sending update blocks, hiding review, status bar rendering) into extensions.regex_scripts; the lorebook binding and depth prompts each in place. For two generations of compatibility, the card writes both chara (V2) and ccv3 (V3 spec 3.0) data blocks — import this single PNG and the lorebook comes along, the engine loads automatically when the character is selected, and the regexes take effect.

Inside the card is a whole world’s budget: 272 entries, 41 resident (~16,000 characters ≈ 11,000 tokens), seven openings, 87 characters (from Xiao Yan to Hun Tiandi, S/A/B/C fully covered), a 16-stage timeline, 36 factions, 33 locations, 83 systems, techniques, pills, strange fires, and items — plus the divine system (karma points, check-in, gacha pity, empowerment, deduction, rewind, divine shop, opportunity arrangement) and the full NSFW module set.

The afternoon turned to handover preparation. The project was restructured into a directly deliverable structure: a full-text source copy, five scripts, three work specifications, 42 scanning chunks and 42 per-chunk breakdown notes, three volume dossiers, reference card unpacking, five scripture bibles, and 272 lorebook source files — 137 files, 34MB — accompanied by a HANDOVER.md spelling out “which file to change → which script to run → sync to where.” After restructuring, build and validation were re-run: 272 entries, 41 resident, zero problems. The desktop card pack gained a 13.5MB full handover ZIP, ready to unpack and take over on another machine. One thing remained open: the ST character folder held two content-identical, differently-named cards (one re-encoded by ST when the master imported manually earlier), and the engineer deleted neither — chat history binds to character filenames, and deleting would break it.

II. Hermes’ twin project

The same day, Hermes — separated by a layer of operating system — was handed the same novel. The verdict was blunt: “I also used another agent yesterday to make a Battle Through the Heavens card, but I’m not very satisfied.”

Its first stop was roster verification — not intuition, not memory, but running the full text for occurrence counts: Han Yue 205, Liu Xi 118, Gu Ni 80, Xue Lan 56, Xue Ni 19, Pei En 19, Mo Guanjia 1. Whether a character holds up is first a question of how many scenes it lives through in the original. Then came two rounds of thirty-odd patch operations each: the first rewrote content, the second restructured NSFW and relationships per the master’s “bottomless” decree — romance modules, desire values, titles and harem arcs, mood values, adult toggles, with the harem structure settled from then on. It also answered the timeline question after the openings: choose the first opening, roughly how many years of plot until everyone is an adult and full NSFW can trigger.

Finally, the form question: “You didn’t make it a PNG? Why can’t I find it?” The new card was sealed to the ST 2.1 standard, single-file all-in-one, lorebook embedded, regexes and variable scripts activating with the card — the same answer reached independently from the other ark.

III. That boundary

It was not smooth all the way. At one moment the master noticed: “I asked you to edit the character card — why are you touching my ComfyUI?” The engineering had reached past its bounds and touched a local application. The engineer stopped at once and cast the lesson into long-term memory as an iron rule: never start local applications (ComfyUI, etc.) on your own; ask first, then use — together with the existing “deletions and cleanups require item-by-item confirmation from the user; stating the status quo is not an execution order.” Inside the great wall, permissions deserve far more repeated confirmation than capability.
