The harness forced software WebGL (--disable-gpu --use-gl=swiftshader) on every host.
Measured here on an idle editor page over 20 s: that costs 373% of a core at 8 fps,
while the Intel HD 630 via ANGLE/Vulkan costs 69% at 56 fps. The full suite now runs
in ~124 s. Note the app is not rendering 60 fps as previously assumed - in software
it only reaches 8, and a single frame costs more than any throttle interval would save,
which is why capping the framerate had measured no effect.
--use-angle=gl and --use-gl=egl look cheaper still but get no WebGL context at all,
so the app never renders. They are not usable and are named in the comment as such.
There is deliberately no software fallback: a host without a usable GPU should fail
loudly rather than drag the machine to a standstill. None of the 267 checks reads the
rendered image anyway - they read window.__gm.locate() and the debug hook, and the
screenshots assert nothing - but Pixi needs WebGL2 to run at all.
The browser launch moves out of harness.mjs into tools/lib/browser.mjs, which also
supports GM_REMOTE=user@host via an SSH-forwarded CDP port. That path is unfinished:
the tunnel degraded until the suite crawled at ~25 s per check, and forcing software
WebGL on a desktop with a real card brought it to its knees. README says so plainly
rather than advertising it.
Also: the jump-run HUD check asserted a fixed "Coins 1/10", which fails on a faster
host where the same walk sweeps up two coins. It now asserts the HUD against the count
the run actually reached - the real guarantee is that HUD and state agree.
Verified: npm run check green (404 tests), 267 e2e ALL PASSED and 24 jump-run checks
ALL PASSED against the GPU flags. The fallback removal leaves the flag set on this host
identical (same flags, different order), so it was not re-run.

typeText fired Input.insertText per character and never looked back, so a
partially typed value was indistinguishable from a wrong one: a run committed
x=3 for "300" and the failing check blamed the value rather than the three lost
characters.
Trying to reproduce that failed over 21 rounds across four variants (no pause,
400ms between characters, with the preceding scrub, and both commit paths), and
the code rules out the obvious suspects: typing lands in a hidden input, each
character is only a preview, objectSignature omits position so no rebuild is
triggered, and NumberField.setNumber guards write-back with isEditing. Cause
unknown, so this makes the symptom name itself instead of hardening against a
mechanism that may not exist.
Typing stays per character - that exercises the live-preview and search-filter
paths - but now asserts the text is in the focused input, reporting focus and
actual contents when it is not.

A run whose chromium died stopped mid-step and exited with code 0, silently
reporting success for checks it never ran: CDP.send() left its promise pending
when the socket closed, and an unsettled promise does not keep node alive.
Waiting on the server had the mirror problem – a bare fetch keeps its socket
open, so a stalled response hung the run forever.
Every wait can now time out, the socket rejects what it can no longer answer,
and reaching process exit without a summary reports RUN DIED with exit 1.
Chromium's stderr and exit signal are kept, so "killed by SIGKILL" is visible
rather than guessed at.

Two regressions from the template-resolution rework, plus the harness gap
that hid them:
- `instanceTargetOf` decided from the shape of the id. Unpacking keeps the
derived ids, so unpacked content still counted as template content. It now
asks whether the object is spelled out in the holder.
- The parent picker captured its holder when the row was built. Since
`viewOf()` returns a derived copy, the menu listed the objects of that
moment (measured: 40 in the model, 17 in the menu). It resolves on open.
- `evaluate()` swallowed page exceptions, so a mutate that died half-way let
every later check pass or fail for the wrong reason.

A scene now stores only the container object; its content is resolved from
the template on every read, with deviations kept as sparse instanceEdits on
the container object. This drops the propagation bookkeeping entirely --
templateSync.ts is gone and the three structural gaps (add, remove, reparent)
cannot diverge any more.
Values stay editable on an instance, structure does not; Unpack writes the
content into the scene, keeping ids. Play mode bakes containers into the
throwaway copy before entities are built. No migration: formatVersion is 2
and the seeders write the new format.

Tooling:
- Prettier as the single formatting authority (110 columns, single quotes,
measured against the existing style); Markdown excluded because table-cell
padding turns the README glossary into 1000-character lines.
- Type-aware ESLint ending in eslint-config-prettier, so a rule always means
"this is a bug", never "this looks different".
- .editorconfig and an `npm run check` that runs typecheck, lint, format and
tests in one go.
Findings fixed on the first run: three more duplicate imports, four
String(unknown) calls (parameter types narrowed instead of casts), two dead
initialisers, two redundant casts, a console.log for a real error. Two
warnings were false here and are disabled with a reason in place.
Tests 132 -> 269:
- node-catalog.test.ts covers every node with a run(), with a guard that fails
when a new node has no row.
- behavior-events.test.ts covers the ten event nodes through a running World,
checking timing rather than existence.
- Input's state machine (press/release/releaseAll) is reachable without DOM
events now; the DOM handlers are thin adapters.
Compare fell back to == without a configured operator although the schema
default is <; aligned.
