Defold — Save and load manual
Official DocsOfficial save API—sys.save / sys.load, slots, and platform paths for desktop Steam bundles.
Use for: save.root verification baseline
GDevelop — Storage extension
Official DocsBrowser + desktop storage—action keys and path behavior when exporting NW.js Steam demos; preview vs packaged path divergence is the dominant fest bug.
Pro tip: document save_path_map.json before branch promotion
Ren'Py — Persistent data
Official DocsCross-session state—persistent store semantics and migration when narrative scripts change mid-freeze.
Best for: schema bump discipline
Ren'Py — Building distributions
Official DocsBuild classification—which labels and assets ship in release vs development builds; pairs with label_inventory_v1.json gates.
Use for: fest RPA packaging
Beginner pipeline—ships collection_map_v1.json + save_root_map_v1.json + defold_steam_audit_receipt_v1.json; this resource is the external link stack.
Start here: Defold teams
Seven-day freeze—locks storage extension paths before October fest upload; gdevelop_freeze_receipt_v1.json gate 4 blocks promotion when paths differ.
Best for: GDevelop + NW.js
Narrative freeze lane—renpy_freeze_receipt_v1.json + label inventory; complements path maps when crashes are Label not found not missing files.
Use for: VN fest demos
Sibling engine—one-evening export + save sanity before Steam upload; same fest cluster discipline as Defold/GDevelop maps.
Best for: GameMaker Studio 2
NW.js AppData lane—package.json name locks and localStorage paths; pairs with upcoming Construct save-path help in fest cluster.
Use for: Construct fest builds
Recovery narrative—branch promotion broke UI slot labels vs on-disk paths; evidence timeline for partner review.
Best for: post-mortem + map JSON motivation
Steamworks — Steam Cloud
Platform DocsCloud vs local path—when fest demos use Cloud sync, local save maps must still document the on-disk canonical path reviewers test offline.
Use for: Cloud-enabled demos
Promotion gates—add save_path column to Wednesday BUILD_RECEIPT metadata diff; fuzz round-trip with 15 save fuzz tools after maps pass byte-match smoke.
Pro tip: never promote fest branch until maps match
