What changes

sdk_version goes from 0.2.31 to 0.2.32. Merging this tags sdk-v0.2.32 and publishes its tarball. sdk-repin then asks each store plugin to repin.

Why now: the SDK's shape has moved three times since 0.2.31, so store plugins built for 0.2.31 don't load in a fizzy built from main. Pixi's history trim (reading fizzy's history limit) needs #620's call.

SDK impact

• None
• Core-only or additive: reaches plugins at the next SDK release
• Fingerprint moved: recorded in sdk/src/version.zig, sdk_version untouched, PR labelled sdk
• SDK release: bumps sdk_version, lists the sdk PRs since the last sdk-v* tag

sdk PRs since sdk-v0.2.31:

• sdk: plugins register demos, and the demos service lists and plays them #608: plugins ship demos.
  • host.registerDemo(.{ .name, .title, .tape }) in register; the host copies them and drops them on unregister.
  • The demos service (sdk.services.demos, version 1) lists every demo fizzy can play and plays one by name.
  • sdk.Demo is new. Nothing existing changed shape.
• sdk: a document's bytes for a checkpoint, without a save's bookkeeping #606: a document's bytes without a save.
  • New optional Plugin.VTable.documentBytes(state, doc, path, allocator): the bytes a save would write, with none of a save's bookkeeping (no format on save, no undo stop). Fizzy uses them for crash checkpoints, a restart's carried work, a tape's file and fizzy.document.changed listeners.
  • An owner without it falls back to documentSnapshot + encodeSnapshot, as before.
• app: the history limit is fizzy's setting, read by every editor #620: the history limit is fizzy's. host.historyLimit() (a new EditorAPI member) is how many steps a document's undo history keeps: fizzy's "Undo steps per document" setting, 0 for no limit. Each plugin that owns a history trims its own.

Also reaching plugins at this release (no boundary change):

• app: go back to before Claude's change, from its bubble or a command #616: Host.Activity gains an optional agent, the author index of an agent's edit.
• backend: a plain app's in-app floating windows are made of the window material #589: the dvui pin moves to the zig-0.17 branch's floating-window background hook (docs/DEPENDENCIES.md, patch 14).
• core: a rounded panel of glass has a drop's rim; the bars lose their rings #614: glass panels in core/dialogs.zig get a drop's rim.

(app/ changes since 0.2.31 are not compiled into plugins.)

Verified

• macOS: scripts/check-fmt.sh and zig build test-sdk-version pass. The fingerprint is main's recorded value (0x3d7fca8d3d211e73); only sdk_version changed.
• Store plugins built against this sdk/ (--fork, Zig 0.17, macOS, sandbox profile): pixi, zig, atlas, drive and ghostty, each from its main, all build.
• Linux: CI

Follow-ups

• Repin and release the store plugins (pixi, zig, ghostty, drive, atlas; then agent and chat, by hand) when sdk-repin opens their PRs.
• Make 0.2.32 live on fizzyed.it/app once the repinned plugins are in the store: gh workflow run web.yml --ref main -f go_live=0.2.32.
