The Driver's print standard: every export is generated when it is asked for, and only previews are
stored. The zone and country map sheets — the poster, and the map-only sheet on a packet's page 1 —
existed only if library/scripts/posters/generate.mjs (Node) had written them ahead of time; no country
had a print-resolution sheet at all.
- library/packet/poster-render.js is generate.mjs's drawing layer (2,645 lines) as a pure factory,
createPosterGenerator({ env, SERIES_DEF, ISO3_NAME, adm0, adm1Ind, adm1Chn, nePlaces, series }). Moved
VERBATIM (template literals carry their whitespace into the output), `process.env` read through a
local shadow; its inputs are its free variables, found by a scope-aware parse, not a grep (a grep
missed adm0, and the proof caught it). generate.mjs is now its Node driver.
- PROVEN BYTE-IDENTICAL: all 118 sheets of a pinned offline matrix — the 28 zones in 3x4, 3x3, letter
and packet, and a country sample at both sheet sizes — hash the same before and after.
- data/zone-sheet.js is which group pins in which zone (first claim wins), now ONE function both the
Node driver and the browser call, so a group cannot pin in one zone on paper and another on screen.
- library/packet/posterSheets.js feeds the factory in the browser: the served full-resolution
boundaries, the shared series and places tables, a generator per call (caching by format pinned the
first caller's data on every later sheet). generateCountrySheet does a country end to end;
data/zone-sheet-print.js a UPG-100 zone. ISO3_NAME moves to library/data (territory-counts re-exports).
- usePosterPrints gains opts.sheet: the poster print is the generated letter sheet as a VECTOR page,
and the packet's page 1 the generated map-only sheet (item.mapId honoured); stored images remain the
fallback when generation fails. PosterWall forwards it; the Country Posters wall, the UPG-100 wall and
the UPG-100 map pass it. The UPG-100 wall and map drop their own record fetches for the shared
provider, and the map's legend and selection HUD offer the card deck (production).
- check:poster-browser-equiv: the browser feed's sheet is byte-identical to the Node generator's for an
India zone (packet) and a country — proven two-sided (it fails when the feed drops the city dots).
check:selection-kinds reads the handler's branches instead of a fixed poster/packet pair, anchored on
`if (` (proven: it fails with the cards branch deleted). library/packet/README.md: the standard.
gates:pre 68/68; both bundles build.
