6b830a54b9 feat(ui): connection requirements — sidebar + modal + drag-A-to-B + inspector
Snapshot now carries connection_requirements; state.requirements is
populated on project switch.

Sidebar:
- New "Requirements" section between Cable types and Tools.
- Each row shows "A ↔ B · cable-type" plus a must/nice badge. Clicking
  a row selects the requirement (inspector pane updates).

+ Requirement modal:
- Device-pair pickers (autocompletes from the project's current devices).
- Cable-type picker with "— solver picks —" as the first option (saves
  preferred_cable_type_id as null on the wire).
- "Must connect" checkbox (default on); notes textarea.
- POSTs to /api/projects/:pid/connection-requirements. 409 collisions
  (reversed-pair duplicates) surface as inline form errors.

Drag-from-A-to-B gesture:
- New tool `req` (keyboard R + "Drag req A→B" button). Arming the tool
  + pointerdown on a device starts a dashed-line preview. Pointerup on
  another device opens the modal with from/to pre-filled. Anywhere
  else cancels. Crosshair cursor while armed.

Inspector:
- Device pane gains a "Requirements" section listing every requirement
  involving the selected device, sorted by the other device's name.
  Each row is clickable → inspector jumps to that requirement.
- New `requirement` selection kind with its own inspector renderer
  showing from/to, cable type, must/nice toggle button, debounced
  notes textarea, "Edit" (re-opens modal), and Delete.

Delete of a device cleans up its requirements in local state (server
already CASCADEs the rows).

d8637de4a0 feat(db): connection_requirements + cables.auto
Migration 003 adds the solver's per-project input table + the auto flag
that slice 6 will use to distinguish solver-owned cables from m's
hand-drawn ones.

connection_requirements:
- (from_device_id, to_device_id, preferred_cable_type_id) with
  preferred_cable_type_id nullable ("solver picks if exactly one type
  matches both ends").
- (pair_lo, pair_hi) is the order-normalised MIN/MAX of (from, to),
  stored alongside the m-facing from/to so the UI doesn't have to
  denormalise.
- UNIQUE (project_id, pair_lo, pair_hi, preferred_cable_type_id) →
  (A,B,T) and (B,A,T) collide; (A,B,Power) + (A,B,RJ45) coexist.
- CHECK (from != to). FK CASCADE from devices → requirement vanishes
  if either endpoint device is deleted.

Store + 11 new tests:
- pair normalisation rejects the reversed-direction duplicate
- different cable types on the same pair coexist
- self-loop rejected (ErrInvalidInput)
- cross-project device reference rejected
- two null-cable-type reqs on the same pair both succeed (SQLite NULL
  != NULL in UNIQUE — semantically "solver picks both times", second
  wins)
- partial PATCH: preferred_cable_type_id tri-state (leave/set/clear),
  must_connect bool, notes string
- device delete cascades to its requirements
- snapshot.connection_requirements is non-nil and populated

cables.auto:
- ALTER TABLE cables ADD COLUMN auto INTEGER NOT NULL DEFAULT 0 CHECK
  (auto IN (0,1)). Slice 6 sets 1 from the solver; slice 7's manual
  cable POST keeps the default 0.

7f0b6e4fab feat(ui): type-aware device creation + port rendering
Modal-driven +Dev (replaces the v3 inline namer):
- Tool armed → click on canvas captures the click position + frame_id
  from frameAt(p), then opens a #modal-new-device dialog.
- Dialog has a <select> grouped by `kind` for built-ins, then
  project-custom rows, then "Custom (no type)" at the bottom.
- Default selection is the first built-in (NAS). Name input is
  auto-pre-filled to <type-name>, bumping to <type-name>-N if a name
  collision is detected in the current device list.
- Submit POSTs name + type_id + x/y/w/h + frame_id. Server seeds the
  ports in the same transaction; we re-snapshot to pick them up.

Canvas:
- After each device's <rect> + label, render the device's ports as
  white-filled <circle>s with stroke = the port's cable_type colour.
- Position: (device.x + port.x_offset, device.y + port.y_offset). The
  seeder's "evenly along the edge" layout means ports already sit on
  the device's bottom edge by default and follow the device on drag
  (because they re-render from the same x/y on every renderCanvas).
- Ports themselves are `pointer-events: none` for slice 4 — selection
  remains device-level. Per-port click semantics ship in slice 7
  (manual cable draw).

Inspector device pane:
- New "type" row showing the type name + a "(custom)" badge for
  project-custom types, or "Custom (no type)" for freeform.
- New "Ports" section with one row per seeded port: cable-type-colour
  swatch, label, "unconnected" placeholder. Label falls back to the
  cable type's name when the seeded label_prefix was blank.

State + snapshot:
- state.ports populated from snap.ports; cleared on project switch /
  404.
- state.deviceTypes hydrated from GET /api/projects/:pid/device-types
  after the snapshot loads. Failure of that fetch is non-fatal — the
  +Dev modal just shows "Custom (no type)" only.
- Delete-device cleans up its ports from state.ports too (server-side
  CASCADE already handles persistence).

0a34dce398 feat(http): device-type endpoints + type_id on device create/patch
- GET /api/device-types — built-ins only (read-only).
- GET /api/projects/:pid/device-types — built-ins + project-custom merged.
- POST/PATCH/DELETE /api/projects/:pid/device-types — project-custom only.
  Mutating a built-in row returns 403 via the new ErrForbidden → 403 map
  in writeError.
- devicePatch / deviceCreate JSON shapes accept type_id (tri-state for
  PATCH via the existing parseFrameRef helper applied to type_id too).
- POST /api/projects/:pid/devices with type_id seeds ports in one tx
  server-side; response carries the device row + the snapshot will then
  carry the new ports.

8cb237fe8e feat(db): device_types store + port seeding on device create
Catalog: 11 built-ins from §2.2 + the v4.1 trio (Screen, Keyboard, Mouse)
seeded in migration 002, totalling 16 built-in types.

Store layer:
- internal/db/device_types.go — CRUD for device_types. Built-ins
  (project_id NULL) reject PATCH/DELETE with new ErrForbidden sentinel
  (handler maps to HTTP 403). Project-custom types accept full CRUD;
  cross-project access returns ErrNotFound. Replacing the port profile
  on UPDATE is one transaction.
- internal/db/ports.go — ListPortsForProject for the snapshot loader +
  seedPortsFromType(tx, …) used by CreateDevice. Layout is "evenly spaced
  along the configured edge", per-edge group ordering by sort_order +
  id. Labels are "<prefix>" for count==1 and "<prefix> N" 1-indexed for
  count>1.
- Device gains a nullable TypeID + tri-state on UpdateDevice. CreateDevice
  validates the type is built-in or a project-custom row of the same
  project, then seeds the device's ports in the same transaction.

Snapshot now populates Ports from the store; field type tightened to
[]Port.

Tests (15 new, all green with -race):
- 16 built-ins seeded with correct names + project_id=NULL + built_in=1
- Port-profile totals match the §2.2 table for every built-in type
- Project-custom create + name-collision-with-built-in → 409 (ErrConflict)
- Per-project name UNIQUE — same custom name across projects is fine
- PATCH/DELETE built-in → ErrForbidden
- Cross-project custom PATCH → ErrNotFound
- CreateDevice with NAS type → 2 ports along bottom edge, evenly spaced,
  labels set
- CreateDevice with PC type → 5 ports incl. "USB 1" + "USB 2"
- CreateDevice without type_id → 0 ports (freeform fallback)
- Cross-project custom type on CreateDevice → ErrInvalidInput
- Snapshot includes the seeded ports

a3f0586296 feat: frontend — IO markers + cable-type inspector
Slice 3 frontend.

+ IO tool (keyboard `I`):
- Single-click on canvas places a 30x30 diamond (rotated <rect>) at the
  point, with the Power-cable_type colour fill (red-ish).
- Inline namer prompts for a label; empty → server defaults to "IO".
- Drop-point determines initial frame_id via the existing frameAt()
  point-in-rect logic, same as devices.

Render:
- io_markers come from snap.io_markers in the snapshot loader. Each
  renders as a <rect> with rotate(45) around its centre + a small text
  label below the diamond. Selection halo on stroke-width.
- Drag is the same pointer-event flow as devices; on pointerup, PATCH
  x,y + recompute frame_id from the new centre. Cross-frame moves
  update frame_id with explicit null on the wire when leaving all frames.
- Frame-drag now also relocates contained IO markers (mirrors the
  device-cascade pattern). Single PATCH per IO marker on release.

Cable-type inspector:
- Clicking a legend row now sets state.selection = {kind:"cable_type", id}
  in addition to toggling activeTypeId. The inspector renders the cable
  type's details (name + colour, both editable, with the
  "shared across projects" banner from v3 §7), a used-by counter (0
  until slice 7 ships cables), and a Delete button that surfaces the
  RESTRICT in_use_by_cables count from the server.
- Debounced rename via the existing bindDebouncedRename helper.

Inspector frame view picks up an "IO" count alongside the device count.
Background click + Esc clear the selection (existing behaviour, now
covers cable_type too).

Hand-tested via the API equivalents: 3 IO markers created (free, in
frame, default-label), PATCH x,y + frame_id-to-null all work, cross-
project frame_id rejected with 400, DELETE 9999 returns 404. Snapshot
shape post-slice-3: {frames, devices, io_markers, cable_types} all
populated, ports/cables/bundles still [].

1ea6082948 feat: db store — IO markers CRUD, snapshot wiring
Schema already in 001_init.sql; this is just the Go store layer.

IO markers are project-scoped wall-outlet terminators (a cable's
"this end plugs into a wall socket outside the diagram" endpoint).
Power-by-convention; no schema-level type enforcement.

- CreateIOMarker validates frame_id is in the same project (cross-project
  ref → ErrInvalidInput), defaults label to "IO" when blank.
- GetIOMarker is project-scoped — wrong-project read returns ErrNotFound.
- UpdateIOMarker uses the FrameRef tri-state for frame_id (same as
  DeviceUpdate) so callers can clear it explicitly.
- DeleteIOMarker is direct delete — ON DELETE SET NULL from the schema
  drops the io_markers.frame_id ref cleanly when the frame is deleted
  (verified by TestDeleteFrame_SetsIOMarkerFrameIDToNull).

Snapshot now populates IOMarkers from the store; field type tightened
from []any to []IOMarker.

7 new table-driven tests, all green with -race.

376ffd8197 merge: design v4.1 — schematic-only, templates folded in
m's review of v4 locked 6 answers. Tight doc pass:
- Schematic-only bundling: dropped trunk-segment/frame-edge/cable-tray
  language. v3 endpoint-pair rule is the only bundle rule.
- Setup templates folded in (not post-MVP): migration 004 with 3
  built-ins (Living Room, Home Office, Server Rack) + 3 new device
  types (Screen, Keyboard, Mouse) + apply-template API in slice 6.
- Unmet-requirement quick-fix: combo endpoint adds a missing port and
  re-solves in one server roundtrip.
- Solver still button-only, catalog still SQL-seeded, promote still
  explicit on cable inspector.

All 9 §9 questions resolved.

e42b351280 docs: design v4.1 — schematic-only bundling, setup templates folded in
Tight pass on m's review of v4 (single commit per head's instruction).

Six locked answers integrated:

1. mCables is a schematic, not a physical-routing tool. Stripped
   'trunk', 'frame-edge corridor', 'cable tray', 'path optimisation'
   from §5b.1, §5b.2, §7, §8, §9. Bundling reduces to the v3 endpoint-
   pair rule: ≥2 cables between the same A↔B endpoint pair → group as
   one bundle. Anything path-shaped is "out of scope, period" (§8).
2. Solver button-only for v0 (no change). Live-solve parked at 9+.
3. Unmet-requirement quick-fix: red badge on the affected device in the
   inspector with a single "+ Add <type> port to <device> and re-solve"
   button per §5b.4. New endpoint
   POST /api/projects/:pid/devices/:id/ports-and-resolve chains the
   port insert + the solve re-run in one transaction.
4. Setup templates fold INTO v4.1. New §2.4 with the schema for
   setup_templates + setup_template_devices + setup_template_requirements
   (migration 004), 3 built-in templates seeded (Living Room, Home
   Office, Server Rack). New API: GET /api/setup-templates,
   POST /api/projects/:pid/apply-template. New UI flow: "or start from
   a template" section in the New Project modal + an "Apply template"
   action on empty projects. Built-in catalog grows to 14 types
   (adds Screen, Keyboard, Mouse).
5. Catalog SQL seed in migration 002 (no change).
6. Promote-to-manual: explicit button on cable inspector (no change).

§8 slice 6 absorbs the templates work alongside the solver MVP.
§9 closes all six v4 questions; no open design questions remain.
Trailer changes to "DESIGN v4.1 READY FOR REVIEW".

CLAUDE.md mirrors: schematic-only framing, 14-type catalog, setup
templates as a first-class feature, quick-fix UX note.

e862a06e9d docs: design v4 — solver-as-core, hybrid device-type catalog, requirements
Big rescope driven by m's product-vision clarification: mCables is a
cable-management framework with a solver as its core value prop, not a
manual draw-and-click editor. m declares devices + required connections
between them; the solver emits the cable plan + bundle recommendations,
optimising for maximum bundling.

Schema additions (migrations 002 + 003):
- device_types (catalog) — built-ins (project_id NULL) + project-custom
  (project_id non-null). 11 built-in types seeded with default port
  profiles (NAS, PC, Mac, TV, Soundbar, Switch, fritz, ChromeCast,
  SteamLink, IOx-3/6/8, Notebook).
- device_type_ports (profile rows: cable_type × count × edge).
- devices.type_id (nullable). Picking a type seeds ports once;
  instance-owned thereafter (no retroactive re-seed).
- connection_requirements (per-project, from/to device + preferred type
  + must_connect flag, with order-normalised pair_lo/pair_hi for
  duplicate prevention).
- cables.auto (slice 5.5 migration) — distinguishes solver-owned cables
  from user-drawn ones.

API additions:
- GET /api/device-types (built-ins only, read-only) and
  GET /api/projects/:pid/device-types (built-ins + project-custom merged)
- POST/PATCH/DELETE under /api/projects/:pid/device-types (project-custom
  only; built-ins are 403)
- /api/projects/:pid/connection-requirements full CRUD
- POST /api/projects/:pid/solve with ?preview=1 — pure-function solver
  (greedy port allocation, endpoint-pair bundling for v0); returns
  add[], remove[], bundles_added[], unsatisfied[], warnings[]

Solver algorithm (§5b):
- Read project devices + ports + connection_requirements + manual cables
- Assign each requirement a (port_a, port_b) using the preferred cable
  type (or auto-pick if exactly one type matches both ends)
- Bundle by endpoint-pair (v3 rule, applied to auto cables only)
- Surface unsatisfied requirements per class (no compat type / ambiguous
  type / no free port) — does NOT auto-add ports; UI quick-fix instead
- ?preview=1 returns the diff without writing; default applies in a tx

UI additions:
- Device-create modal: type dropdown (built-ins grouped by kind, then
  project-custom, then "Custom (no type)" for the v3 freeform fallback)
- Left-sidebar Requirements section with + Requirement button
- Header Solve button (S keybinding) → preview modal → Apply
- Inspector for selected device: type, ports grid, unmet requirements
  with red badges + quick-fix actions
- Inspector for selected auto cable: driving requirement, parent bundle,
  Promote-to-manual button

Slice reshape (§8):
- Slices 1, 2 shipped. v4 inserts: 4 = catalog + type-aware device create,
  4.5 = catalog management, 5 = requirements CRUD + UI, 6 = solver MVP +
  Solve button. Old "manual port + manual cable draw" slides to slice 7
  as a tweak path on solver output. Export becomes slice 8.

Six new open questions (§9) for m to gate before slice 4:
1. Path source (auto-route through frame edges / user cable-trays /
   Steiner-tree)?
2. Live-solve vs. button-only?
3. UX when solver has no compatible port pair?
4. Setup templates in v4 or post-MVP?
5. Catalog as code seed or JSON file?
6. Auto-promote vs. explicit Promote-to-manual on solver cable edits?

CLAUDE.md updated to reflect the solver-core framing, hybrid catalog,
connection-requirements model, and auto/manual cable distinction.

4f862e741a merge: fix inspector not updating on device/frame selection

29e221e080 fix(ui): inspector now updates on device/frame selection
startDrag set state.selection but didn't render until pointerup's onUp
ran — and onUp can throw on `e.currentTarget.classList.remove` if the
event reference is stale after pointer capture release, which leaves
the inspector stuck on 'Nothing selected.'

One-line fix: call render() right after state.selection assignment so
the inspector + halo update from pointerdown, independent of whether
onUp completes cleanly. The drag-completion render at the end of onUp
stays — when both fire it's idempotent (renders are pure functions of
state).

c7dfbe010c merge: fix +Dev inline-namer blur (sherlock's preventDefault diagnosis)
Primary fix: e.preventDefault() on the pointerdown for both armed-tool
branches in onCanvasPointerDown. Without it, the browser's default
mousedown action blurs the freshly-focused input in promptInline
(the SVG click target isn't focusable), and the blur handler calls
done(null) before m can type.

Secondary fix: clear activeNamer before fo.remove() in done(), to
prevent a re-entrant pageerror when Enter triggers blur synchronously.

12804619b2 fix(ui): +Dev inline-namer kept getting blurred by default mousedown
Root cause traced by sherlock with Playwright (docs/sherlock-+dev-bug.md
on the sherlock branch). The previous routing fix at 94869f3 was
necessary but not sufficient: placeDeviceAt() now reaches promptInline()
correctly, but the synchronous input.focus() is undone ~6ms later by
the browser's compatibility-mousedown default — which blurs the active
element when the mousedown landed on a non-focusable target (SVG rect /
SVG root). The blur listener then ran done(null) and ripped the
<foreignObject> out before m could type a name.

Primary fix: e.preventDefault() at the top of both armed-tool branches
in onCanvasPointerDown. Suppresses the focus-shifting default so the
input keeps focus.

+Frame is also wrapped for symmetry. It wasn't strictly affected (its
namer runs from pointerup, not pointerdown) but preventDefault avoids
a subtle text-selection side effect during rubber-band drag.

Secondary fix in promptInline.done(): clear activeNamer *before*
fo.remove(). Enter-key triggers a synchronous blur listener which
re-enters done() — if remove() ran first, the re-entry hit a
"node no longer a child" pageerror. Reordering makes the re-entry a
no-op (activeNamer is already null).

Verified locally: served /main.js shows e.preventDefault() inside both
tool branches and the reordered done() body. go test -race ./... still
green.

"maximum bundling" objective is satisfied by the endpoint-pair rule
(when two or more cables share the same A↔B endpoint pair, group them
into one bundle). The visual editor is still there for tweaking the
plan, but the solver is the headline.

promotes it to manual (explicit "Promote to manual" button in the

mCables shifts from a manual draw-and-click editor to a **solver** that
takes a list of devices + the connections m needs and emits the cable
plan + bundle recommendations. The manual editor stays (it's the only way
to inspect + tweak the plan) but is no longer the primary surface.

> ChromeCast, SteamLink, IOx-3/6/8, Notebook, …) with default port
> profiles (`device_type_ports` rows: cable_type + count + label).
> Adding a device → pick a type → ports auto-seed. m can override per
> instance (this PC has 3 USB, not 2). Catalog is extendable per project.
> - **`connection_requirements` table** (§2.2). m declares "NAS must
> connect to Switch via RJ45" once. Many per device. The solver consumes
> these.
> - **`POST /api/projects/:pid/solve` endpoint** (§3.2). Reads devices +

> of `cables` + `bundles`. Two modes: `?preview=1` returns the diff
> without applying; default applies.
> - **Solver objective: maximum bundling** (§5b.1). Schematic only: when
> two or more cables share the same endpoint pair, group them into one
> bundle. No path or trunk geometry — mCables is a wiring schematic,
> not a routing tool. v4.1 strips all path/trunk language from the v4
> draft.

### 2.1 Migration sequence
- **001_init.sql** (v3) — projects, frames, devices (no type_id), ports,
cable_types (5 seeded), io_markers, cables, bundles, bundle_cables.
- **002_device_catalog.sql** (v4) — `device_types` +
`device_type_ports`. Seeds the built-in catalog (§2.2). Adds
`devices.type_id` (`ALTER TABLE devices ADD COLUMN type_id INTEGER
REFERENCES device_types(id) ON DELETE SET NULL`) and the matching
index.
- **003_connection_requirements.sql** (v4) — `connection_requirements`.
Also adds `cables.auto` (`ALTER TABLE cables ADD COLUMN auto INTEGER
NOT NULL DEFAULT 0`) so the solver can distinguish its rows from
m's hand-drawn ones (§5b.3).
- **004_setup_templates.sql** (v4.1 NEW) — `setup_templates` +
`setup_template_devices` + `setup_template_requirements`. Seeds 3
built-in templates ('Living Room', 'Home Office', 'Server Rack').
Slices 1 and 2 already shipped 001. Slice 4 lands 002; slice 5 lands
003; slice 6 lands 004 alongside the solver MVP + templates UI.
### 2.2 Built-in catalog seed (002 INSERTs)
The 14 built-in types m's setup uses today, with their default port
profiles. Stored as `(project_id NULL, built_in 1)`. v4.1 added the
three peripheral types (Screen, Keyboard, Mouse) to support the Home
Office setup template:
| `device_types.name` | `kind` | Default ports (cable_type × count) |
|---|---|---|
| NAS | storage | Power × 1; RJ45 × 1 |
| PC | compute | Power × 1; RJ45 × 1; HDMI × 1; USB × 2 |
| Mac | compute | Power × 1; HDMI × 1; USB × 2 |
| Notebook | compute | Power × 1; USB × 2 |
| TV | display | Power × 1; HDMI × 2 |
| Soundbar | audio | Power × 1; HDMI × 1 |
| Switch | network | Power × 1; RJ45 × 5 |
| fritz | network | Power × 1; RJ45 × 4 |
| ChromeCast | display | Power × 1; HDMI × 1 |
| SteamLink | compute | Power × 1; HDMI × 1; USB × 2 |
| IOx-3 | hub | Power × 1; (3× port slots — concrete cable type per slot is set at instantiation; defaults to USB × 3 for v0) |
| IOx-6 | hub | Power × 1; USB × 6 |
| IOx-8 | hub | Power × 1; USB × 8 |
| **Screen** | display | Power × 1; HDMI × 1 |
| **Keyboard** | accessory | USB × 1 |
| **Mouse** | accessory | USB × 1 |
"Hub" devices like IOx-* have ambiguous port profiles (the seed drawing
shows them in red because most carry Power, but they also hub USB). v0
seeds them as USB hubs; m overrides per-instance. The catalog is editable
in the UI (slice 4.5 — "Manage device types") so m can refine the IOx-3
profile once and not re-override every instance.
m can also add **project-custom types** at any time (UI: "+ New device
type" inside the device-create modal) with `project_id = current`.
### 2.3 Why ports are still instance-owned
When m picks a type to create a device, the seeder calls `count` × INSERT
into `ports`. From that moment on, ports are instance-level rows owned by
that device. Deleting a port from this PC doesn't touch other PCs;
changing a type's port profile (in slice 4.5) doesn't retroactively
re-seed already-created devices — it only affects subsequent device
creations.
Trade-off acknowledged: m may want a "re-seed from type" action later
(slice 5+) to wipe + reset a device's ports. Out of v0 scope; not
blocked by the schema.
### 2.4 Setup templates (v4.1 NEW)
A setup template is a named recipe of "device-types to add + connection
requirements between them" that bootstraps a project from blank to
solver-ready in one click. m's three archetypes:
| Template name | Devices | Default requirements |
|---|---|---|
| **Living Room** | TV, Soundbar, ChromeCast | TV ↔ Soundbar (HDMI, must); TV ↔ ChromeCast (HDMI, must) |
| **Home Office** | PC, Screen, Keyboard, Mouse | PC ↔ Screen (HDMI, must); PC ↔ Keyboard (USB, must); PC ↔ Mouse (USB, must) |
| **Server Rack** | NAS, Switch, fritz | NAS ↔ Switch (RJ45, must); Switch ↔ fritz (RJ45, must); fritz ↔ NAS (Power, nice) |
> "Screen", "Keyboard", "Mouse" are added to the v4 built-in catalog
> alongside the existing 11 (Screen: Power × 1 + HDMI × 1; Keyboard: USB × 1;
> Mouse: USB × 1). Migration 002 grows to seed 14 built-ins.

- Requirements whose endpoints both resolve fire;
any whose endpoint was skipped are themselves
skipped (logged in `requirements_skipped[]` — same

## 5b. v4 — Solver
The solver is the headline addition in v4. m's product-vision sentence
maps onto it directly:
> "I say what devices we have, the app tells me how to bundle cables and
> how the most efficient connection looks like"
The solver reads a project's `devices` (with their `ports`) and
`connection_requirements`, and writes a set of solver-owned `cables`
(rows with `auto=1`) + `bundles`. m's hand-drawn cables (`auto=0`) are
left strictly alone — the solver only adds and removes its own.
### 5b.1 Objective: maximum bundling — schematic only
mCables is a **schematic**, not a physical-routing tool. Cables are
straight lines between endpoints; the solver has no model of walls,
floors, cable trays, or path geometry. "Maximum bundling" therefore
reduces to a single rule on the schematic:
> When two or more cables share the same endpoint pair (device A ↔
> device B), group them into one bundle.
This is the v3 endpoint-pair rule, applied to the solver's output. m's
"visually cleaner setups" benefit comes from the bundle being a single
labelled set in the inspector + a single mixed-colour glyph in the
render (slice 9+), rather than from any path optimisation. Anything
about trunks, frame-edge corridors, or auto-routing is out of scope —
filed for "post-v0 ambient" in §8.
### 5b.2 Algorithm (v0)
Pure function. No graph search; no LP; no path optimisation. Single
pass with greedy port allocation.
```
solve(project) ⇒ {add, remove, bundles, unsatisfied}:
let auto_cables_before = SELECT * FROM cables WHERE project=p AND auto=1
let port_free := {port_id -> bool} initialised TRUE for every port
minus ports already used by manual cables (auto=0)
for each requirement r in order(must_connect DESC, id ASC):
let ct = r.preferred_cable_type_id
?? auto_pick_cable_type(r.from_device, r.to_device)
?? fail("ambiguous")
let pa = first_free_port(r.from_device, ct, port_free)
let pb = first_free_port(r.to_device, ct, port_free)
if !pa or !pb:
if r.must_connect: unsatisfied.push({r.id, reason})
else: skip
continue
port_free[pa] = port_free[pb] = false
add.push(cable{type=ct, from_port=pa, to_port=pb, auto=1})
// Bundle by endpoint-pair (v3 rule, applied only to auto cables).
for each (device_a, device_b) pair with ≥ 2 add-cables:
bundles_add.push({auto=1, cables: those add-cables})
// Diff against auto_cables_before to compute remove[] (any prior auto
// cable whose (from, to, type) doesn't appear in add[]).
remove = auto_cables_before - add
return {add, remove, bundles_add, unsatisfied}
```
`first_free_port(device, cable_type, free_map)` picks the lowest-id port
on the device whose `type_id` matches and that is still free, returning
NULL if none. The `lowest-id` tiebreak is deterministic so repeated
solves produce the same plan.
`auto_pick_cable_type(from, to)` (used when `preferred_cable_type_id` is
NULL): find the set of cable types `T = ports(from).types ∩
ports(to).types`. If `|T| == 1`, return it. If `|T| > 1`, fail
("ambiguous; specify preferred_cable_type_id"). The UI surfaces this
as a "specify type" inline edit on the requirement.
### 5b.3 Solver-owned vs. user-owned cables
`cables.auto` distinguishes them.
| Operation | Effect on `auto=0` cables | Effect on `auto=1` cables |
|---|---|---|
| POST /api/.../cables (m draws by hand) | inserts auto=0 | n/a |
| PATCH cables (m moves endpoint, relabels) | applies | applies (and the cable is "promoted" to auto=0 — m owns it now) |
| DELETE cables | applies | applies |
| POST /api/.../solve | left alone (their used ports are reserved before the solver runs) | replaced wholesale (remove[] + add[] in one tx) |
This way a manual cable m doesn't want the solver to second-guess
survives every solve. If m wants the solver to take it over, he deletes
his hand-drawn cable and re-solves; the solver re-creates an equivalent
auto cable.
### 5b.4 When solver fails — quick-fix UX
Three classes of failure surface in the response's `unsatisfied[]`:
1. **No compatible cable type** — `T = ports(from).types ∩
ports(to).types` is empty (e.g. a Power-only device to an HDMI-only
device).
2. **Ambiguous cable type** — `|T| > 1`, no preferred set on the
requirement.
3. **No free port** — the cable type matches but every port on one side
is already used.
The solver does **not** auto-add ports without m's consent. v4.1 ships
an explicit one-click quick-fix per class of failure, surfaced as a red
badge on the affected device in the inspector (§7) and as a button on
each `unsatisfied[]` entry in the preview-diff modal:
| Failure class | Quick-fix button | What it does |
|---|---|---|
| No compatible cable type | **"+ Add &lt;preferred_type&gt; port to &lt;device&gt; and re-solve"** | POST `/api/projects/:pid/devices/:id/ports` with `type_id=preferred_type` + sensible default offset, then immediately POST `/solve` again. The preferred_type is the requirement's `preferred_cable_type_id`. If the requirement has no preferred type, the button reads "Specify cable type" and opens an inline cable-type picker on the requirement instead. |
| Ambiguous cable type | **"Specify cable type"** | Opens an inline picker on the requirement row with the candidates from `T` pre-listed. On select → PATCH the requirement → re-solve. |
| No free port | **"+ Add &lt;type&gt; port to &lt;device&gt; and re-solve"** | Same as the no-compat case but the `type` is already determined (it's the requirement's preferred or auto-picked type). Adds a port on whichever side ran out (the response's `reason` carries `which_side`). |
All three quick-fixes do their work in a single round-trip request from
the UI perspective: the click fires a POST that either chains the port
insert + the re-solve server-side, or fires both calls back-to-back from
the client (server-side chaining is simpler — see §3.2 for the endpoint
shape).
The quick-fix never adds a port silently; the button text always names
the device + cable type so m sees what's about to mutate.
### 5b.5 Preview vs. apply
`?preview=1` returns the same shape without writing. The UI shows a diff
modal with `add[]`, `remove[]`, `unsatisfied[]`; m clicks Apply to fire
the same endpoint without `preview=1`. Default (no flag) applies
immediately. Live-solve (no Solve button — every requirement edit
triggers a debounced re-solve) is parked at slice 9+ as an opt-in.

The New Project modal gains a **"or start from a template"** section
under the description field. Each built-in template ('Living Room',
'Home Office', 'Server Rack') is a clickable card listing its devices +
the requirement edges between them. Selecting one expands an inline
override form:
- A pre-filled name for each template device (m can edit each, e.g.
rename `TV` to `Bedroom TV`).
- Per-device "skip" checkbox.
On Create, the server does `POST /api/projects` first; on success,
immediately fires `POST /api/projects/:pid/apply-template` with the
collected overrides. The response's `devices_added` + `requirements_added`
are merged into the local snapshot and the project switches to it,
already populated.
For an already-existing empty project, the inspector's project header
shows an **"Apply template"** action that opens the same override form
without the project-create round-trip.

## 8. First slices
## 8. First slices — v4 reshape
Each slice ends with something m can click. The first coder shift takes
slices 14 as the MVP; slice 5 (export) is the round-trip end.
Slices 1 + 2 have shipped (see git history). v4 inserts new slices ahead
of the original 3-5 because the solver depends on the catalog + the
requirements model, not on manual cable drawing. The old "manual port +
cable draw" slice is still in scope as a tweak path on the solver
output, but it follows the solver instead of leading.
| # | Slice | What's shipped |
|---|---|---|
| 1 | **Bootstrap + project CRUD** | `cmd/mcables` Go binary, SQLite migrations. Migration 001 seeds the 5 default cable types (Power/USB/HDMI/DP/RJ45) **globally, once**. `internal/db` store. `POST /api/projects` auto-fills `drawing_name = <name>.excalidraw` when omitted. `DELETE /api/projects/:pid?confirm=<name>` with name-match guardrail. `GET /api/projects` lists them. `GET /api/projects/:pid` returns a (mostly empty) snapshot. `GET /api/cable-types` returns the 5 seeded rows. Frontend `index.html` + `main.js` shows the project picker, a "+ New Project" modal, and an empty SVG canvas with the legend rendered from the global `cable_types` table. m can create LOFT, see it picked, see no devices. |
| 2 | **Add frame, add device, drag-to-position** | `+ Frm` and `+ Dev` tools work. Devices and frames persist. Drag-to-position writes back to DB on `pointerup`. Reload returns to the same layout. m builds LOFT's `desk` and `rack` frames and drops in his first devices. |
| 3 | **Add port, draw cable** | `+ Port` (with a device selected) places type-coloured ports on device edges with offsets. Click-port → click-port creates a cable. Cables auto-route as straight lines. Inspector shows the cable's type, endpoints, label. m wires up the first end-to-end cable. |
| 4 | **IO markers + cable-type editing** | `+ IO` places a wall-outlet diamond. Cable-from-port → IO commits as `to_io_id`. Legend swatch is a colour picker; renaming a type updates the legend on the fly. `+ Type` adds new types. m can fully recreate LOFT's visual model from scratch. |
| 5 | **Export to mxdrw.msbls.de** | `POST .../sync/export` generates a `.excalidraw` scene that reproduces the seed's visual grammar (ports as positional ellipses, IO as diamonds, legend as text in the top-left), writes it via mExDraw API, and stores the assigned `excalidraw_id`s for stability on re-export. m sees LOFT in Excalidraw and confirms the look matches the seed. |

Migration adds `devices.type_id`. API: `GET /api/device-types`, `GET /api/projects/:pid/device-types`. Frontend: the +Dev inline namer becomes a type dropdown + name input; choosing a built-in type seeds the device's ports on the backend. Picking `Custom (no type)` falls back to v3 freeform. m can create a typed NAS + see its Power + RJ45 ports appear on the canvas. |
| **4.5 (NEW)** | **Manage device-type catalog (per project)** | pending | Modal: `POST/PATCH/DELETE /api/projects/:pid/device-types` for project-custom rows. Edit affordance hidden for built-ins. Lets m add an exotic device type without contributing to the built-in catalog. Validation: a custom type can't share a name with a built-in (already enforced by `UNIQUE(project_id, name)` + a separate code-level check against built-ins). |
| **5 (NEW)** | **Connection requirements UI + CRUD** | pending | Migration 003: `connection_requirements`. API: full CRUD under `/api/projects/:pid/connection-requirements`. Frontend: left-sidebar "Requirements" section, `+ Requirement` modal (autocomplete from project's current devices, cable-type picker, must/nice toggle). Drag from device A to device B gestures the same modal pre-filled. Inspector for a selected device lists its requirements. |
| **6 (v4.1 EXPANDED)** | **Solver MVP + Solve button + setup templates** | pending | `POST /api/projects/:pid/solve` with `?preview=1` support. v0 algorithm (§5b.2): pure-function, greedy port allocation, endpoint-pair bundling. Migration 003 adds `cables.auto`. Header gains a Solve button that opens the preview-diff modal. m clicks Solve → sees the cable plan + unmet requirements (each with its quick-fix button per §5b.4) → applies. **Folded in v4.1: setup templates.** Migration 004 adds `setup_templates` + `setup_template_devices` + `setup_template_requirements` and seeds 3 built-ins ('Living Room', 'Home Office', 'Server Rack'). API: `GET /api/setup-templates`, `POST /api/projects/:pid/apply-template`. UI: a "Templates" section in the New Project modal + an "Apply template" action on empty projects → seeds devices + requirements in one transaction → Solve produces the wired diagram. |
| **7 (was 3, slimmed)** | **Manual port + manual cable draw** | pending | The v3 flow as a tweak path on solver output. `+ Port` on an instance-owned device; click-port → click-port creates a hand-drawn cable (`auto=0`). Used to override the solver's choices or to extend its plan. |
| **8 (was 5)** | **Export to mxdrw.msbls.de** | pending | `POST .../sync/export` writes a `.excalidraw` scene per the visual grammar (§4). Bundles ignored on export in v0. |
Slices 6+ (not promised for the first coder shift):
bundle suggestions UI; bundle rendering (thick path with mixed-colour
fan-out); cable type "warn on cross-type port-to-port"; cable inventory
metadata (length/SKU) if m later wants it; dark mode.
Slices 9+ (not promised for the first coder shift):
- Live-solve mode: re-run solver on every device/requirement edit with a debounce + previewed-but-not-applied diff in a toast. Opt-in toggle in project settings.
- Bundle rendering in the SVG (a single thick line with mixed-colour stops between the endpoint pair, plus a small badge with the cable count). Cables in a bundle still render as their individual lines underneath; the bundle is a visual overlay m can toggle.
- "Re-seed from type" action on a device.
- Custom setup templates (m authors them in-UI, not just the built-in three).
- Cable inventory metadata (length/SKU) if m later wants it.
- Dark mode.
Out of scope, period (would change mCables's mental model): path
routing, cable-tray polylines, frame-edge corridors, wall-axis bundling,
3D, anything that treats a cable as more than a labelled endpoint pair.

2. **Device-name uniqueness within a project** → `UNIQUE (project_id,

3. **Non-Power IO markers** → no `type_id` on `io_markers` for v0.
Power-by-convention; UI soft-warns on non-Power cables to an IO. (§2, §7)
4. **Bundle render in export v1** → bundles ignored on export until slice
6+. (§4, §5)
5. **Cross-project cable types** → `cable_types` is fully **global**. One
shared legend; renaming/recolouring affects every project. (§2, §3, §7)
6. **Project deletion guardrail** → `DELETE /api/projects/:pid?confirm=<name>`
required; server validates name match, returns 400 otherwise. (§3)
1. **Where do paths come from?** → **Nowhere — mCables is a schematic.**
Cables are straight lines between endpoints. The solver does not
route, the renderer does not route, and "maximum bundling" reduces to
the endpoint-pair rule (§5b.1). Anything resembling a path, trunk,
cable tray, or frame-edge corridor is **out of scope, period**
(§8 "Out of scope, period").
2. **Live solve or button-only?** → **Button-only for v0.** Live-solve
stays parked at slice 9+ as an opt-in.
3. **No-compatible-port-pair UX.** → **Explicit quick-fix.** The
unsatisfied-requirement badge in the inspector carries a single
button — "+ Add &lt;type&gt; port to &lt;device&gt; and re-solve" —
that POSTs the port AND fires `/solve` in one UI action. The button
text always names the device + type, so m sees what's about to
mutate (§5b.4 + §7).
4. **Setup templates.** → **Folded INTO v4.1, in slice 6.** Migration 004
adds `setup_templates` + child tables + 3 built-ins. `GET
/api/setup-templates` and `POST /api/projects/:pid/apply-template`
ship alongside the solver (§2.4 + §3 + slice 6 in §8). Custom
templates (m authors his own) parked at slice 9+.
5. **Catalog distribution.** → **SQL seed in migration 002.** No
external file loader.
6. **Promote to manual.** → **Explicit button** on the cable inspector
(§7 row "cable (auto=1)"). PATCHes that only update labels stay auto.
No open design questions remain. The coder shift is gated on m's
go/no-go for v3 — not on any unanswered design question from picasso.
