Deleting a node cost its source with no way back. Every mutation already
funnels through one commit, so undo/redo is a bounded stack of node
snapshots replayed through the same debounced save. Deleting a node only
drops it from flow.json — the source file survives — so restoring the id
restores the code. Renaming a message now offers to follow the rename
across every node still bound to the old name, as one undoable step.
Autosave never fired: flush depended on the whole mutation object, which
react-query rebuilds every render, so the effect re-ran and its cleanup
cancelled the pending timer. Unmounting now flushes rather than drops.
The canvas looked blurry zoomed out because Background scales the dot
radius by zoom, leaving quarter-pixel dots on a drifting tile; radius
and spacing now divide the zoom back out, spacing in octaves so the grid
halves. Edge value labels are opaque, the edge popover fits its summary
on one row with a trash icon and scrolls names that overflow, and flow
settings moved to the flowbar. The flowbar was sized against the
viewport rather than the canvas, so its buttons left the screen once
enough flows were open.

pytest was deleting every user on teardown against the development
database. The engine is built at import time, so tests/__init__.py pins
POSTGRES_DB before app.core.config loads; the fixture creates the schema
and drops the database again, guarded against a name that is not _test.
Playwright now defaults at the integrated stack, which is the origin the
API allows, so a bare `bunx playwright test` works without a dev server.
The four template specs that asserted copy we no longer ship are gone,
along with the helpers they were the last callers of. The admin edit
assertion was page-wide and only ever passed on a fresh database.

- MQTT nodes failed to build: the topic map was renamed to talk in ports, but
__slots__ still declared the old name, so every MQTT node raised
AttributeError. Building one of each node type is now a test, since __slots__
makes this failure invisible until someone places the node.
- Port names offer the messages already in play: everything published is worth
reading, and an input nobody provides yet is worth publishing. A message only
connects when both ends spell it the same way, so choosing beats typing.
- Adding a port focuses its name field.
- Dragging onto an input that already reads something offers the extra port as
well as the replacement — an MQTT or InfluxDB node usually wants both.
- The template's Item model, its routes, screens and table are gone.

The browser half of M3. Flows open on a full-bleed canvas with their chrome
floating over it: flow tabs top, dock bottom, node settings in a panel on the
right that leaves the graph visible and running behind it.
- Connections are derived, not stored. A node declares the messages it reads
and publishes; every matching pair draws an edge, so two producers of one
message converge on their consumer. Dragging output to input is shorthand
for pointing that input at the producer's message, and asks before it
replaces an existing one.
- Values land on the edges as they flow, over a websocket that feeds a store
outside React, so a value arriving re-renders its own chip and nothing else.
Clicking an edge shows the last payload and when it arrived.
- Node source is edited in Monaco, loaded only when a panel opens and themed
from the design tokens.
- Edits autosave; identical documents are skipped server-side, so a quiet
canvas writes nothing.
- Validation from the API shows on the node it belongs to and is summarised in
the dock, where each entry pans to its node.
- Works on a phone: touch-connect, 44px dock targets, and the node panel
becomes a full-screen sheet.
Two new tokens (--status-success, --font-mono) are mirrored in the website repo
and recorded in DESIGN-GUIDELINES.md.

The submodule collapse was only half applied: .gitmodules was deleted but
backend/ and frontend/ were still recorded as gitlinks, so none of their
files were tracked. Replace the gitlinks with the real trees.
Also untrack .env (it carried placeholder secrets) in favour of a tracked
.env.example, drop the committed __pycache__, and narrow the blanket *.png
ignore that would have swallowed design assets.
