2a46ce744b 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.

Trailer changes to "DESIGN v4 READY FOR REVIEW".

# CableGUI — Project Instructions
# mCables — Project Instructions
## Project Overview
Cable-management **framework + solver** for m's setup. m declares his
**devices** and the **connection requirements** between them ("NAS must
connect to Switch via RJ45"). CableGUI runs a solver that emits the cable
plan + bundle recommendations. CableGUI is a **schematic**, not a
physical-routing tool — cables are straight lines between endpoints; the
"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.

### 5b.1 Objective: maximum bundling — schematic only
### 5b.1 Objective: maximum bundling
CableGUI 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:
Locked in by m. Prefer routes that consolidate cables into shared trunks
even at higher total length. Visually cleaner setups; easier to manage
physically (one cable bundle along the floor, not five strands).
> 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.
Concretely: when assigning a cable to a path, the solver minimises the
**count of distinct trunks**, breaking ties by total length. v0
approximates a "trunk" with the pair of device endpoints (the v3 rule);
slice 6+ adds path-based trunks via frame-edge corridors.

Three classes of failure surface in the response's `unsatisfied[]`:
1. **No compatible cable type** — `T = ports(from).types ∩

device).

the devices.

type on the requirement.
3. **No free port** — the cable type matches but every port on one side
is already used.
is already used. UX: drop a must_connect=0 requirement, or add ports.
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.
The solver does **not** auto-add ports to a device. Reason: m said
"override per instance"; auto-adding crosses that line. The UI surfaces
the unmet requirement with a "+ Add port" affordance on the device
inspector instead.
### 5b.5 Preview vs. apply

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.

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.
1. **Where do paths come from?** v0 draws straight lines port-to-port +
bundles by endpoint-pair. Three candidates for slice 6.5/9:
(a) auto-route through frame edges (cables exit a device toward the
nearest frame edge, traverse along edges, enter the target frame);
(b) m draws **cable-tray polylines** on the canvas and cables snap to
them; (c) Steiner-tree-ish path optimisation per trunk. I lean (b) +
(a) as fallback — m gets the manual override when his layout is
non-obvious, otherwise the system routes for him. Confirm direction.
No open design questions remain. The coder shift is gated on m's
go/no-go for v4.1 — not on any unanswered design question from picasso.
2. **Live solve or button-only?** Two modes available:
- **Button-only** (locked default) — m hits Solve, sees the diff,
applies. Simple; no surprises.
- **Live** — solver re-runs on every device/requirement edit with a
debounce, results land in a toast "12 cables, 3 bundles, 1 unmet
— review?". More responsive, costs ~10ms of compute per edit.
I'd ship button-only first (slice 6); add live as an opt-in toggle
(slice 9+). Confirm or escalate to "live always".
3. **No-compatible-port-pair UX when solving.** Three options:
(a) Surface as "unsatisfiable" and let m manually add a port via the
device inspector (current §5b.4 stance).
(b) Auto-add the missing port to the device on the m's confirmation
(single-button "Add HDMI to PC and re-solve").
(c) Auto-add silently — bad UX, surprise mutations.
I lean (a) with a one-click quick-fix that does (b). Confirm.
4. **Setup templates — v4 or post-MVP?** "Living Room" / "Home Office" /
"Server Rack" archetypes that pre-populate `connection_requirements`.
I left this out of the v4 slice list (designed in §8 "slices 9+") to
keep v4 tight. m can build the same effect by adding requirements
manually first time. Confirm: post-MVP OK, or do you want me to fold
it into slice 5/6?
5. **Catalog distribution: code seed vs. JSON file.** Two paths:
(a) seed in migration 002 via SQL INSERTs (today's design — locked-in,
schema versioned, no user override of built-ins).
(b) seed from a curated JSON file at `internal/db/catalog/builtin.json`
that the migration reads. m or contributors can extend the file by
PR; rebuild image; new built-ins appear.
I lean (a) for v0 (simpler, doesn't need a file-loader). Open
question: do you anticipate growing the built-in list often? If yes,
(b) starts paying off after the second addition.
6. **Promoting a solver cable to manual.** §5b.3 says PATCHing an
`auto=1` cable flips it to `auto=0` so the next solve doesn't replace
it. Two surface variants:
(a) Implicit: any PATCH that touches type/from/to on an auto cable
promotes it. m never sees the flag.
(b) Explicit: a "Promote to manual" button on the cable inspector
(current §7 stance). PATCHes that only update labels stay auto.
I leaned (b) for clarity ("the solver might overwrite this — promote
to protect"). Confirm or override.

## 11. v5 — Cable routing via clamps
m's bundling primitive: a **clamp** is a physical anchor on the canvas
(think cable tie / clip). A cable routes from its `from` endpoint,
through zero or more clamps **in order**, to its `to` endpoint. Two
cables that share an ordered pair of consecutive clamps are visibly
bundled along that segment — no detection pass, no inference: the
overlap *is* the bundle.
This replaces the abandoned waypoints + segment-detection approach.
v0's straight-line schematic stays as the empty-clamps case
(`cable_clamps` is empty for a fresh solver-emitted cable).
### 11.1 Schema (migration 007)
```sql
CREATE TABLE clamps (
id INTEGER PRIMARY KEY,
project_id INTEGER NOT NULL REFERENCES projects(id) ON DELETE CASCADE,
x REAL NOT NULL,
y REAL NOT NULL,
label TEXT NOT NULL DEFAULT '',
frame_id INTEGER REFERENCES frames(id) ON DELETE SET NULL,
excalidraw_id TEXT,
created_at TEXT NOT NULL DEFAULT (datetime('now')),
updated_at TEXT NOT NULL DEFAULT (datetime('now')),
UNIQUE (project_id, excalidraw_id)
);
CREATE INDEX clamps_project_idx ON clamps(project_id);
CREATE TABLE cable_clamps (
cable_id INTEGER NOT NULL REFERENCES cables(id) ON DELETE CASCADE,
clamp_id INTEGER NOT NULL REFERENCES clamps(id) ON DELETE CASCADE,
ord INTEGER NOT NULL, -- 1..N along from→to
PRIMARY KEY (cable_id, ord),
UNIQUE (cable_id, clamp_id) -- a cable can't visit the same clamp twice
);
CREATE INDEX cable_clamps_clamp_idx ON cable_clamps(clamp_id);
```
`frame_id` on clamps mirrors devices + IO markers — m can put a clamp
inside a frame and the frame-drag carries it.
`UNIQUE (cable_id, clamp_id)` blocks loops. `ord` is a small int, 1-based;
nothing requires it to be contiguous (m can renumber 1, 2, 3 → 1, 3, 5
during edits and the renderer is fine with that), but the UI keeps them
contiguous on every mutation for sanity.
### 11.2 Cable rendering model
Each cable resolves to a polyline `[from-anchor, clamp₁, clamp₂, …, clampₙ, to-anchor]`
where:
- `from-anchor` / `to-anchor` come from the existing `anchorForEndpoint`
resolver (port / device / IO).
- clamp anchors are `(clamp.x, clamp.y)` directly — clamps don't have a
width/height to centre.
For N=0 clamps the result is the v0 straight line. For N≥1 we render
a `<polyline>` instead of a `<line>`.
The endpoint-replug handles from §10 (cable-replug) stay on the **first
and last** vertices. Mid-polyline vertices get their own clamp-handle —
small grab points only on the selected cable, which behave like
clamp-detach when dragged onto empty canvas (drop a clamp off the
cable's path).
### 11.3 Bundle visualisation — derived from shared segments
A **segment** is a directed pair `(A, B)` where A and B are consecutive
nodes of a cable's polyline. Two cables share a segment when their
polyline contains the same A→B (or B→A — segment matching is
undirected).
For each segment, compute `cables[]` — the cables that traverse it.
If `len(cables) ≥ 2`, render the segment as a single thick line on top
of the individual ones:
- **Width**: `2 + N` px (N = cable count). Caps at ~12 px.
- **Colour**: a striped pattern, one stripe per distinct cable type in
the bundle, ordered by cable_type.id. SVG `<linearGradient>` with
hard stops produces the stripe band cheaply; render it on a sibling
`<polyline>` over the individual lines.
- **Tooltip**: `<title>` child listing the cables ("Power · USB · HDMI").
At a clamp where ≥ 2 cables meet, the clamp icon (10×10 rounded square)
shows a small count badge (`×N`) when N > 1. At fan-out points
(endpoint with no clamp before it on the polyline) the individual
coloured lines re-emerge, so m sees which port each strand goes to.
Shared-segment computation is O(C·N̄) where C = #cables and N̄ = average
polyline length. For a v0-sized project (≤ ~30 cables, ≤ ~5 clamps per
cable) this is trivial. We rebuild the segment map on every renderCanvas
— no caching layer.
### 11.4 UI gestures
**+ Clamp tool (`C` shortcut, also a sidebar button):**
- Click empty canvas → place a clamp at the cursor (POST `/clamps`).
Standalone clamp — not on any cable yet.
- Click a cable line → insert this clamp into that cable. The new clamp
sits at the click position (snapped to the nearest point on the
cable's polyline) and its `ord` is computed so it falls between the
two existing vertices it lies between.
**Drag a cable's mid-segment:**
- Pointerdown on a cable line (not on an endpoint handle) and drag.
Live preview shows a bend at the cursor. Pointerup:
- If the cursor is within snap-radius (~16 px) of an existing clamp:
insert that clamp into the cable's polyline at the right `ord`.
- Otherwise: create a fresh clamp at the release point and insert it.
**Clamp inspector** (selecting a clamp on the canvas):
- Position (x, y editable + label)
- "Cables through this clamp": list with each cable's two endpoints,
click → select that cable
- "Remove from this cable" (per row) → DELETE the matching cable_clamps
row; cable's polyline collapses around the gap.
- "Delete clamp" → cascade-removes from every cable_clamps row.
**Right-click on a clamp icon ON a cable** → "Remove from this cable"
inline.
**Frame drag** carries clamps the same way it carries devices + IO
markers (clamp.frame_id mirrors the existing pattern, drag handler
already iterates frame-contained items).
### 11.5 Relationship to the existing `bundles` table
**Recommendation: keep `bundles` and `bundle_cables`, repurpose them.**
- Implicit/auto bundles → derived live from shared clamp segments. No
DB rows. The §5 `GET /bundles/suggestions` endpoint stays useful as a
"you might want to route these through the same clamps" hint.
- Explicit named bundles → still in the `bundles` table. m names a
group ("desk → wall trunk"), the UI offers "route all members through
these clamps" as a one-click action. Useful for the case where m
wants a stable label on a logical bundle that isn't yet routed.
Migration 007 leaves `bundles` + `bundle_cables` untouched. A v6 cleanup
can drop them if m decides the explicit-named path isn't worth keeping.
### 11.6 Solver coupling
The v0 solver still emits **straight cables** — no clamp rows. m
hand-routes after Solve. The solver's preview-diff is unaffected
(solver compares endpoint pairs; clamp routing is independent of the
endpoint identity).
Future v5.1: solver-suggested clamps based on shared paths between
endpoint pairs. Out of scope here.
### 11.7 Export to mxdrw
Clamps map to small diamond elements (separate from IO markers — IO
diamonds are red wall-outlets; clamps are grey routing points).
`excalidraw_id` is stable across re-exports per the existing pattern.
Cable arrows become Excalidraw `arrow` elements with mid-points (the
clamp positions) when N≥1 — Excalidraw supports multi-vertex arrows
via the `points` array. Each `startBinding` / `endBinding` resolves to
the from/to anchor's excalidraw_id; mid-vertices are unbound.
Bundle visualisation (thick striped lines on shared segments) is **not
exported** in v0 — Excalidraw doesn't natively support gradient strokes,
and the mxdrw round-trip would lose them. We export each cable as its
own polyline; bundling is a viewer-only concept.
### 11.8 API additions
```
POST /api/projects/:pid/clamps { x, y, label?, frame_id? } → Clamp
PATCH /api/projects/:pid/clamps/:id { x?, y?, label?, frame_id? } → Clamp
DELETE /api/projects/:pid/clamps/:id
POST /api/projects/:pid/cables/:cid/clamps { clamp_id, ord? } → CableClamp
DELETE /api/projects/:pid/cables/:cid/clamps/:cmid
# Convenience: re-order clamps on a cable in one call
PUT /api/projects/:pid/cables/:cid/clamps { clamp_ids: [int, int, …] }
```
Snapshot endpoint grows two arrays:
- `clamps: []Clamp`
- `cable_clamps: []{ cable_id, clamp_id, ord }`
### 11.9 Open questions for m
1. **Clamp icon shape.** Diamond (overlaps visually with IO markers
when zoomed out), small filled circle (overlaps with port circles),
or rounded square `` 10×10? Recommend rounded square — distinct from
everything else on the canvas today.
2. **Snap radius when inserting onto a cable.** ~16 px world-units feels
right at 1× zoom. Should it scale with zoom (visual constant) or stay
world-constant (gesture stays the same regardless of zoom)? Recommend
visual constant — divide by current zoom.
3. **Clamp deletion when shared.** If a clamp is used by 4 cables and m
clicks "Delete clamp", do we (a) refuse with a "still in use" prompt,
(b) cascade-remove from all 4 cables, or (c) cascade silently? Current
draft says cascade silently. Worth a confirmation?
4. **Bundle stripe order.** Cable-type id is stable but arbitrary; visual
order on a thick line affects readability. Order by stripe-count
(Power first if 3 Power + 1 USB), or by cable-type-id (deterministic
but unrelated to importance)? Recommend by-count, ties broken by id.
5. **Solver respect for existing routing.** When m re-runs Solve after
hand-routing, should the solver preserve existing clamp routing on
user-owned (`auto=0`) cables? Auto cables are wiped + rebuilt, so
their clamps disappear with them — that's expected. But manual cables
with clamps should clearly keep them. Confirm.
### 11.10 Slice plan (post-design)
1. Schema migration + tx-aware store helpers (Create/Update/DeleteClamp,
AttachClampToCable, DetachClampFromCable, ReorderClamps).
2. HTTP endpoints + snapshot extension.
3. Frontend: clamp render + + Clamp tool + canvas placement (no
cable attach yet).
4. Cable polyline render via clamps, mid-segment drag-to-clamp,
clamp inspector.
5. Shared-segment bundle visualisation (gradient stripe + count badge).
6. Export pipeline extension — mxdrw arrows with mid-points + clamp
diamonds. Bundle viz stays viewer-only.

--
-- v4 seeded the IOx-3 / IOx-6 / IOx-8 as USB hubs (Power × 1 + USB × N),
-- but m's physical IOx-* devices are power strips (1 power input on
-- the back, N power outputs on the front). v5's Multi-plug 3/4/5/6
-- profiles also lumped every Power port on the bottom edge without
-- distinguishing the input from the outputs.
--
-- This migration replaces the port profile for the 8 power-distribution
-- types with the canonical "1 in (top/back) + N out (bottom/front)"
-- layout. Convention: top=back, bottom=front.
--
-- N for each type:
-- IOx-3 / Multi-plug 3 → 3 outputs
-- IOx-6 → 6 outputs
-- IOx-8 → 8 outputs
-- Multi-plug 4 → 4 outputs
-- Multi-plug 5 → 5 outputs
-- Multi-plug 6 → 6 outputs
-- Wifi-plug → 1 output (it's a pass-through outlet)
--
-- Existing devices m may have created with the old profile keep their
-- already-seeded ports — per design §2.3, ports are instance-owned. To
-- get the new layout on an existing instance, delete it and re-create.

// Algorithm:
// 1. Read all auto cables, manual cables, ports, requirements.

// - Find lowest-id free port on each side. None → unsatisfied
// (no free port). Reserve both.
// - Stage an "add cable {from_port, to_port, type, auto=1}".
