OneCAD-Simulation/REBRAND.md

OneCAD Simulation rebrand map (identity layer)

OneCAD Simulation is the OneBSpace fork of FieldCraft (a pure-Rust CAE app: FEA, meshing, thermal, LBM CFD, with a WASM web app at apps/fieldcraft-web). The rebrand is source-level for everything the user can see or click; only the compatibility layer keeps upstream names (so .fieldcraft files, crate names, storage keys and internal identifiers stay upstream-compatible, and every upstream sync stays a clean merge). Files tagged // OneBSpace (OneCAD Simulation): are downstream-only deltas — one tag per edited site, above or beside the change, so the whole fork layer can be found with grep -rn "OneBSpace (OneCAD Simulation)".

Rebranded in source (user-visible)

Layer	Change
Web page	<title>OneCAD Simulation, description and social-card meta renamed; upstream's tangency-labs.github.io/fieldcraft og:url/og:image/twitter:image dropped; loading, no-JavaScript and could-not-start text say "OneCAD Simulation" (apps/fieldcraft-web/index.html)
App bar	upstream's drawn fringe-cube vector mark dropped; a painted OneCAD Simulation wordmark (appbar.rs::APP_NAME) shows in every width variant — the compact bar keeps the name and the quick actions start after the measured wordmark (bar_layout gained a name_w argument)
Help menu	Samples, navigation help, Crash Reports…, Settings… and the version label OneCAD Simulation {VERSION} remain; upstream's Report a Bug… (GitHub draft), Check for Updates and Reinstall FieldCraft… items and their handler branches are removed (appbar.rs::help_menu)
Bug/crash reports	fully local: the Report-a-Bug form's Open GitHub Issue became a Copy report button — the draft (title, fields, session) goes to the clipboard and attachments to the local bug-reports/ folder; nothing opens a browser, ISSUE_URL is never opened (report.rs::copy_report); crash questions/headings say "OneCAD Simulation closed unexpectedly / hit an internal error"
Crash messages	the engine's unclean-exit and native-crash messages (rendered in the crash dialog and the copied report) name the fork (engine/src/crash.rs)
Command catalogue	diagnostics.bug_report and app.update.check palette help texts describe the local draft / name the fork (engine/src/cmd/diagnostics.rs, engine/src/cmd/update.rs)
Updates (desktop-only)	every status line, the notice and the install dialog say "OneCAD Simulation" (updates.rs); the web build has no update host, so none of this runs in the browser; "What's new"/release URLs stay desktop-only logic, rebranded text only
Privacy	consent question and dialog title, Settings copy and tooltips say "OneCAD Simulation"; the upstream GitHub PRIVACY_URL is no longer rendered as a link nor opened — the privacy note is plain text (privacy.rs); the constant is kept for reference
Navigation	the default mouse-mapping preset's label is "OneCAD Simulation" (its id: "fieldcraft" stays, preferences depend on it)
Desktop window	window title / run_native app name "OneCAD Simulation" (apps/fieldcraft/src/main.rs; the APP_ID reverse-DNS id stays)
Attachments	the bug-report session attachment is onecadsim-session.json (engine/src/bug_report.rs::SESSION_FILE); the model attachment keeps the .fieldcraft name

Stays upstream (compatibility & scale)

• The .fieldcraft file-format extension (and model.fieldcraft attachment naming); crate names and the Cargo workspace layout — untouched, so upstream syncs stay mergeable.
• localStorage keys (fieldcraft-recovery/, fieldcraft-prefs) and the browser recovery folder layout.
• HTML element ids (fieldcraft_canvas, fieldcraft_loading) and the trunk tags in apps/fieldcraft-web/index.html.
• Environment variable names (FIELDCRAFT_POSTHOG_KEY, FIELDCRAFT_TELEMETRY, FIELDCRAFT_CONTROL_PORT, …). Telemetry logic is untouched: the Odoo build simply does not set FIELDCRAFT_POSTHOG_KEY, so the PostHog sender stays inert; no key or host URL is surfaced in the UI.
• Internal identifiers: egui window/id salts (fc_appbar, fc_report_bug, …), command ids (diagnostics.bug_report), the fieldcraft nav-preset id, SESSION_FILE/ISSUE_URL API names, the fieldcraft-cli binary name quoted in report text.
• Desktop-only updater internals (release URLs, package layouts) keep upstream strings — unreachable from the web build.

Not touched here

crates/ui-egui/src/files.rs and apps/fieldcraft-web/src/{web,main}.rs plus odoo/* are owned by other agents in this task train; their user-visible strings are handled there.
