OPTIONAL V2 SCENARIO WORKSHOP — SEPARATE EDITION
/games/isocity/v2/
V2 changes/assembly kit (not standalone): /games/isocity/isocity-source-v2-kit.tar.gz
Required immutable v1 base source: /games/isocity/isocity-source-v1.tar.gz
Download BOTH archives. Extract the kit; its offline Python stdlib assembler verifies the base SHA and every output file, then reconstructs the complete self-contained v2 city source into a fresh directory. No network or game-code execution during assembly. Read the kit README; the kit alone is not the game source.
Exact v2 evidence and hashes: /games/isocity/v2-manifest.json
Local tiny recipe export/import on one fixed 40×40 map; separate v2 saves, not migrated from v1. Use one game tab at a time.
Open Settings → Scenario Workshop. Choose a starting budget and optional self-set goal, then Review scenario and explicitly Start reviewed scenario as a separate city. The workshop backs up the current v2 city before switching; retain your own exported backup too. V1 saves are not automatically migrated into v2.
Download reviewed recipe or Download this city’s recipe exports tiny data, NOT progress or editable game source. Import a recipe file or paste its JSON, review it and explicitly start. Recipes carry the fixed base identity, budget and optional goal; no code, arbitrary names or URLs. Reproducing a recipe reproduces its initial map/budget, not later simulation: later simulation is nondeterministic. Goals are self-set, not enforced by automatic win/loss rules.
Return a tiny v2 recipe at /isocity/recipe-review: strict data validation, full pinned preview and explicit consent send it to the existing private feedback inbox. No automatic publication or cross-game mixing. Use /remix-return for a complete source/build remix instead.
Bounded desktop workshop check, 31 October 2026: a $25,000 start afforded one $15,000 project and left $10,000; a second was blocked. A $100,000 start afforded two of the same projects and left $70,000. A $50,000 start and road left $49,975. Explicit saves/reloads and restoration of the original 70×70 city passed. A 189-byte recipe export/import reproduced the initial layout and budget. File-picker cancellation, newer-file/stale-review handling, keyboard use and a 556-pixel-wide layout were checked. Goal completion, full balance, physical mobile devices and long sessions remain unverified.

REUSE
MIT; retain original and dependency notices.
Pinned upstream WebP art under the repository-level MIT declaration. AI-generation workflow documented upstream; no independent per-image provenance guarantee. Protected themed pack excluded.

TWO DIFFERENT REMIX PATHS
City data: Settings → Copy Game State exports a city, not the game source. Keep a copy outside browser storage. Import Game State accepts reviewed formats up to 16 MiB and 200×200; arbitrary old/future formats are not promised compatible. Import replaces the current city, so back it up first. Never paste private information.
Code: download and extract the complete corresponding source, read its README and notices, install locked dependencies, change one mechanic and follow the documented build/export commands. Test construction, economy, export/import and save/reload after changes. Keep credit and component licences.
English-only solo adaptation; co-op, analytics, remote fonts and the protected themed pack are excluded. No account, server or cloud-save service is required by the game. Browser data clearing can remove saves.

VERIFICATION
Bounded desktop check on 31 October 2026 of the prefixed static release: two full 70×70 imports, each followed by explicit Save → reload → Continue. Simulation advanced from 66 to 88 residents and monthly income from −174 to −154; the saved 88-resident city restored. The second import restored the baseline of 66 residents, $95,456 and monthly −174. Malformed input was rejected without changing the city. No Chromium Error 9 was observed during this bounded run; no cause or general stability claim is established. Mobile and long-session acceptance remain unverified.
This is not independent creator acceptance, a complete quality review or a cross-game mashup.

RETURN
Use /remix-return for private manual review. Supply your own public source/build references, pinned parents, changes, licence notes and actual tests. Sending does not publish a game. This multi-file project is not compatible with the single-file HTML uploader.
