Three stale-project-identity fixes from reviewing the New-workspace flow:
- New workspace (web): handleNewClick cleared the workspace and the
current project but left the browser on the old /user/slug URL — a
refresh (or back-button pop) silently reloaded the OLD project over
the fresh unsaved workspace. Now replaceState's to the localized
/editor (replace, not push, so no back-entry points at the stale
project route).
- New workspace (desktop menu): same URL fix for the newProject menu
action, which cleared identity but never left the project route.
- .vlx import: importVlxFile mutated the stores WITHOUT clearing
currentProject — with a saved project open, autosave saw the
imported content as dirty edits on the old projectId and silently
PUT the .vlx contents over the user's saved project (and pushed the
clobber to GitHub on linked projects). Now severs identity first,
same guard loadExample.ts already documents.
Phase 2 of the run-system/UX work.
- BoardInstance gains an optional user ; boardDisplayName(board) resolver
(name || kind label) routes every INSTANCE-label surface: file-explorer
section header, compile console (EditorToolbar), canvas selector/tooltip/
context-menu, Serial Monitor tabs, Oscilloscope board picker, Board Options
subtitle. Board/component pickers keep the KIND label (they pick new boards).
- Inline rename on board AND chip section headers (double-click the name, or a
hover pencil button). Board -> updateBoard(id,{name}); chip -> chipName in
properties. Enter commits, Escape cancels (cancel-flag ref guards the
unmount-fires-onBlur footgun), empty clears to the kind / 'Custom Chip'.
- FileTabs shows an owner badge naming the board/chip whose files are shown
(resolved as a selector so it doesn't re-render on every sim pin toggle).
- CustomChipDialog no longer clobbers a user-given chipName: chip.json's name
only seeds the blank defaults (My Chip / Custom Chip); loading an example
relabels explicitly.
- Persistence: board name round-trips via projectPayload (+ dirty hash),
vlxFile, ProjectByIdPage load + loadProjectState; chipName rides components_json.
- Drive-by: fixed a pre-existing rules-of-hooks violation in BoardOptionsModal
(early return before a useCallback).
Reviewed by a 3-agent adversarial pass (completeness / persistence / correctness);
all major findings folded in.

A programmable custom-chip (a CPU emulator that runs a ROM/program, e.g. the
Z80 or 8080) now keeps its program (larson.s, chaser.c, ...) in a dedicated
editor file group — group-chip-<chipId> — rendered as its own collapsible
section in the file explorer, exactly like each board owns its sketch group.
Behaviour/driver chips and predefined chips carry no programFile and get no
group; they stay editable only in the chip designer.
Fixes two reported issues on the Z80 examples:
- /example/z80-larson-no-board: the board-less chip example now opens its
program (larson.s) as the active group, editable on the left — previously
the editor showed but no file appeared.
- /example/z80-led-chaser-c: the chip program (chaser.c) no longer shows as
a sibling tab inside the Arduino sketch group; it sits in its own chip
section instead. The board group shows only sketch.ino.
Details:
- useEditorStore: chipFileGroupId()/CHIP_GROUP_PREFIX helpers.
- loadExample: seedChipProgramGroups() routes each chip's programFile into its
own group (seeded from the example files), sweeps stale chip groups, keeps
the program OUT of the board group, and for a board-less chip example makes
the chip group active so the program is the editable file shown.
- EditorToolbar.prepareCustomChips: resolves the program from the chip's own
group (falls back to board files for older projects) before assembling ROM.
- FileExplorer: renders one collapsible section per programmable chip with an
IC icon; clicking switches the editor to the chip group. Lazy-creates a
group for chips dropped on the canvas.
- projectPayload + vlxFile: serialise chip groups alongside board groups and
include them in the dirty-check hash, so chip-program edits persist on
save / autosave / .vlx export and round-trip via replaceFileGroups on load.
- Regression tests for board-less + board+chip routing and stale-group sweep.

Phase 4 of the OSS / pro split. The OSS image has no auth and no
server-side persistence — without this commit, the user's workspace
was ephemeral (lost on tab refresh). `.vlx` is a single-file JSON
snapshot of the entire workspace (boards, file groups, components,
wires, active board id) that the user can save to disk and reload
later.
New: utils/vlxFile.ts
- buildVlxPayload() / buildVlxBlob() — pure snapshot of the current
editor + simulator stores.
- triggerDownloadVlx({ name? }) — anchor-click download with a safe
filename. Returns the filename actually used.
- parseVlxFile(File) — async reader + validator. Checks
format === "velxio-project", version <= 1, and the required
arrays/objects are present. Throws VlxParseError with a human-
readable message on any issue.
- importVlxFile(File) — convenience wrapper that parses AND calls
useSimulatorStore.loadProjectState() with the result.
Format intentionally mirrors the server's POST /api/projects body so
a Pro user can export-from-pro and import-into-OSS losslessly (and
vice-versa once Pro adds an Export button — out of scope here).
lib/proSaveAction.ts: the default (no-overlay) implementation now
calls triggerDownloadVlx() instead of console.info'ing about the
missing handler. The Pro overlay still wins via installSaveActionImpl()
— Save in Pro keeps opening SaveProjectModal. The Save button in OSS
now actually saves.
components/editor/FileExplorer.tsx: new "Open .vlx" button next to
New + Save. Opens a hidden file input; confirms with the user before
replacing the workspace (loadProjectState is destructive); surfaces
VlxParseError messages via window.alert.
Verified with both builds:
- OSS-only: triggerSaveAction → download .vlx; FileExplorer shows
3 buttons (New, Open, Save).
- OSS + overlay: Pro's installSaveActionImpl overrides — Save opens
SaveProjectModal as before. Open .vlx still works (independent
button, not part of the save flow).
