# Shelf-Mounted Devices Implementation Plan
> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
**Goal:** Model cabinet/tower PCs that sit on a rack shelf — the shelf reserves a U-range, occupants attach via `mounted_on`/`shelf_face`/`shelf_slot` — and render them as side-by-side boxes in the elevation.
**Architecture:** Extend `scripts/gen_rack.py`: a `mounted_on` branch in `validate_item`, a skip in `check_overlaps`, a new `check_shelves` cross-item validator, and shelf rendering in `render_svg` (a shelf strip plus per-occupant boxes subdividing the column) and `render_page` (occupancy rows for mounted devices). Then populate the worked example. No generator-config or CI changes.
**Tech Stack:** Python 3 (stdlib + PyYAML only), pytest, MkDocs Material, Forgejo Actions CI.
**Spec:** `notes/dev/specs/2026-06-24-rack-shelves-design.md`.
## Global Constraints
- Scripts use **stdlib + PyYAML only**; deterministic and offline (copy existing `gen_rack.py` style). No randomness/time in generated output.
- `re` and `yaml` are already imported in `scripts/gen_rack.py`; do not add new imports.
- Validation failures raise `SchemaError`; `generate` prints `ERROR: …` to stderr and returns `1`, **writing nothing** on failure.
- A **mounted device** declares `mounted_on` (str), `shelf_face` ∈ {front, rear}, `shelf_slot` (int ≥ 1), and **omits** `rack_u`/`u_height`/`rack_face`. A **shelf** (`kind: shelf`) is placed normally (`rack_u`/`u_height`/`rack_face: both`) and reserves the assembly's U-range.
- Peer/PDU/grouping fields (`power:`, `links:`, `cluster:`) on a mounted device are unchanged — they key off hostname, not placement.
- Reuse the existing `item()` and `_write_item` test helpers in `tests/test_gen_rack.py`; add a local `shelf()` helper where noted.
- `isinstance(x, int)` style (bool-is-int acceptable, matching existing code).
- Provisional placeholder data only (matches the existing `srvNN` positions and power/network demos).
- **No edits** to `mkdocs.yml`, `Makefile`, `.forgejo/workflows/docs.yml`, or `scripts/overview_config.yml` (`shelf`/`server` already in the enum; drift already covers `racks/`).
- `mkdocs build --strict` must pass; `make docs-check` must exit 0 after regeneration.
---
### Task 1: Validation — mounted branch, overlap skip, `check_shelves` (TDD)
**Files:**
- Modify: `scripts/gen_rack.py` (add `SHELF_FACES`; `validate_item` mounted branch; `check_overlaps` skip; new `check_shelves`; call it in `generate`)
- Modify: `tests/test_gen_rack.py` (append tests + a `shelf()` helper)
**Interfaces:**
- Consumes: `SchemaError`, `item()`/`_write_item` helpers, `generate`.
- Produces:
- `SHELF_FACES = {"front", "rear"}` (constant)
- `check_shelves(items: list[dict]) -> None` — raises `SchemaError` on a bad mount.
- `validate_item` and `check_overlaps` gain mounted-item handling.
- [ ] **Step 1: Append a `shelf()` helper and failing tests to `tests/test_gen_rack.py`**
Add near the top, just after the existing `item()` helper:
```python
def shelf(**kw):
base = {"hostname": "shf01", "kind": "shelf", "status": "in-use",
"rack": "rack01", "rack_u": 37, "u_height": 10, "rack_face": "both"}
base.update(kw)
return base
```
Append these tests at the end of the file:
```python
def test_validate_accepts_mounted_item():
gen_rack.validate_item(item(hostname="srv01", mounted_on="shf01",
shelf_face="front", shelf_slot=1))
def test_validate_rejects_mounted_with_rack_u():
with pytest.raises(gen_rack.SchemaError):
gen_rack.validate_item(item(hostname="srv01", mounted_on="shf01",
shelf_face="front", shelf_slot=1, rack_u=5))
def test_validate_rejects_mounted_bad_shelf_face():
with pytest.raises(gen_rack.SchemaError):
gen_rack.validate_item(item(hostname="srv01", mounted_on="shf01",
shelf_face="left", shelf_slot=1))
def test_validate_rejects_mounted_bad_slot():
with pytest.raises(gen_rack.SchemaError):
gen_rack.validate_item(item(hostname="srv01", mounted_on="shf01",
shelf_face="front", shelf_slot=0))
def test_overlaps_skips_mounted_items():
items = [
item(hostname="a", mounted_on="shf01", shelf_face="front", shelf_slot=1),
item(hostname="b", mounted_on="shf01", shelf_face="front", shelf_slot=2),
]
gen_rack.check_overlaps(items) # no raise — mounted items claim no U-range
def test_check_shelves_accepts_valid_mount():
items = [shelf(),
item(hostname="srv01", mounted_on="shf01",
shelf_face="front", shelf_slot=1)]
gen_rack.check_shelves(items)
def test_check_shelves_rejects_missing_shelf():
items = [item(hostname="srv01", mounted_on="ghost",
shelf_face="front", shelf_slot=1)]
with pytest.raises(gen_rack.SchemaError):
gen_rack.check_shelves(items)
def test_check_shelves_rejects_non_shelf_target():
items = [
item(hostname="sw01", kind="switch", rack_u=10, u_height=1,
rack_face="front"),
item(hostname="srv01", mounted_on="sw01",
shelf_face="front", shelf_slot=1),
]
with pytest.raises(gen_rack.SchemaError):
gen_rack.check_shelves(items)
def test_check_shelves_rejects_duplicate_slot():
items = [shelf(),
item(hostname="srv01", mounted_on="shf01",
shelf_face="front", shelf_slot=1),
item(hostname="srv02", mounted_on="shf01",
shelf_face="front", shelf_slot=1)]
with pytest.raises(gen_rack.SchemaError):
gen_rack.check_shelves(items)
def test_generate_returns_1_on_dangling_mount(tmp_path):
hw = tmp_path / "hardware"
out = tmp_path / "out"
hw.mkdir()
_write_item(
hw, "srv01",
"---\nhostname: srv01\nkind: server\nstatus: in-use\n"
"rack: rack01\nmounted_on: ghost\nshelf_face: front\nshelf_slot: 1\n---\n",
)
rc = gen_rack.generate(hw, out)
assert rc == 1
assert not (out / "rack01.md").exists()
```
- [ ] **Step 2: Run to verify failure**
Run: `pytest tests/test_gen_rack.py -q`
Expected: FAIL — `AttributeError: module 'gen_rack' has no attribute 'check_shelves'` (and the mounted-validation tests fail because `validate_item` rejects the missing `rack_face`).
- [ ] **Step 3: Add the `SHELF_FACES` constant**
In `scripts/gen_rack.py`, just after the existing `ZERO_U_FACES = {"left", "right"}` line, add:
```python
SHELF_FACES = {"front", "rear"}
```
- [ ] **Step 4: Add the mounted branch to `validate_item`**
In `validate_item`, the function currently begins:
```python
def validate_item(fm: dict) -> None:
name = fm.get("hostname") or fm.get("_path", "?")
rack = fm.get("rack")
if not isinstance(rack, str) or not rack:
raise SchemaError(f"{name}: rack must be a non-empty string")
face = fm.get("rack_face")
```
Insert the mounted branch between the `rack` check and the `face = …` line, so it reads:
```python
def validate_item(fm: dict) -> None:
name = fm.get("hostname") or fm.get("_path", "?")
rack = fm.get("rack")
if not isinstance(rack, str) or not rack:
raise SchemaError(f"{name}: rack must be a non-empty string")
if "mounted_on" in fm:
mounted_on = fm.get("mounted_on")
if not isinstance(mounted_on, str) or not mounted_on:
raise SchemaError(f"{name}: mounted_on must be a non-empty string")
for forbidden in ("rack_u", "u_height", "rack_face"):
if forbidden in fm:
raise SchemaError(
f"{name}: mounted item must omit {forbidden}"
)
sface = fm.get("shelf_face")
if sface not in SHELF_FACES:
raise SchemaError(
f"{name}: shelf_face={sface!r} not in {sorted(SHELF_FACES)}"
)
slot = fm.get("shelf_slot")
if not isinstance(slot, int) or slot < 1:
raise SchemaError(f"{name}: shelf_slot must be an integer >= 1")
return
face = fm.get("rack_face")
```
(The rest of `validate_item` — the `face`/0U/U-range checks — is unchanged.)
- [ ] **Step 5: Skip mounted items in `check_overlaps`**
In `check_overlaps`, the loop body currently starts:
```python
for fm in items:
face = fm.get("rack_face")
if face in ZERO_U_FACES:
continue
```
Add a mounted skip as the first thing in the loop:
```python
for fm in items:
if "mounted_on" in fm:
continue
face = fm.get("rack_face")
if face in ZERO_U_FACES:
continue
```
- [ ] **Step 6: Add `check_shelves` after `check_overlaps`**
Add this function immediately after `check_overlaps` in `scripts/gen_rack.py`:
```python
def check_shelves(items: list[dict]) -> None:
"""Validate shelf-mounted devices within one rack.
Every mounted_on resolves to a placed kind:shelf item in the same rack;
no two devices share (shelf, face, slot).
"""
by_host = {fm.get("hostname"): fm for fm in items}
occupied: dict[tuple[str, str, int], str] = {}
for fm in items:
if "mounted_on" not in fm:
continue
name = fm.get("hostname", "?")
shelf_name = fm["mounted_on"]
target = by_host.get(shelf_name)
if target is None:
raise SchemaError(
f"{name}: mounted_on={shelf_name!r} is not in this rack"
)
if target.get("kind") != "shelf":
raise SchemaError(
f"{name}: mounted_on={shelf_name!r} is not a kind:shelf item"
)
if not isinstance(target.get("rack_u"), int) or not isinstance(
target.get("u_height"), int
):
raise SchemaError(
f"{name}: shelf {shelf_name!r} is not placed (needs rack_u/u_height)"
)
key = (shelf_name, fm["shelf_face"], fm["shelf_slot"])
if key in occupied:
raise SchemaError(
f"{shelf_name} {fm['shelf_face']} slot {fm['shelf_slot']}: "
f"{name} overlaps {occupied[key]}"
)
occupied[key] = name
```
- [ ] **Step 7: Wire `check_shelves` into `generate`**
In `generate`, the per-rack validation loop currently reads:
```python
try:
check_overlaps(ritems)
validate_power(ritems)
validate_links(ritems, hw_index)
except SchemaError as e:
errors.append(f"{rack}: {e}")
```
Add `check_shelves(ritems)`:
```python
try:
check_overlaps(ritems)
validate_power(ritems)
validate_links(ritems, hw_index)
check_shelves(ritems)
except SchemaError as e:
errors.append(f"{rack}: {e}")
```
- [ ] **Step 8: Run to verify pass**
Run: `pytest tests/test_gen_rack.py -q`
Expected: PASS (all prior tests + 10 new).
- [ ] **Step 9: Commit**
```bash
git add scripts/gen_rack.py tests/test_gen_rack.py
git commit -m "feat(rack): validate shelf-mounted devices (mounted_on/shelf_face/shelf_slot)"
```
---
### Task 2: Rendering — shelf strip + occupant boxes + occupancy rows (TDD)
**Files:**
- Modify: `scripts/gen_rack.py` (`render_svg` shelf drawing; `render_page` occupancy)
- Modify: `tests/test_gen_rack.py` (append tests)
**Interfaces:**
- Consumes: `render_svg`, `render_page`, the `shelf()` helper (Task 1).
- Produces: `render_svg`/`render_page` render shelves and mounted occupants. No new public function.
- [ ] **Step 1: Append failing tests to `tests/test_gen_rack.py`**
```python
def test_render_svg_draws_shelf_and_occupants():
items = [
shelf(),
item(hostname="srv01", mounted_on="shf01", shelf_face="front", shelf_slot=1),
item(hostname="srv02", mounted_on="shf01", shelf_face="front", shelf_slot=2),
item(hostname="srv03", mounted_on="shf01", shelf_face="rear", shelf_slot=1),
]
svg = gen_rack.render_svg("rack01", items)
assert "shf01" in svg
assert "srv01" in svg and "srv02" in svg and "srv03" in svg
# the shelf is NOT drawn as a generic full-height device box
assert "shf01 (U37" not in svg
def test_render_svg_shelf_is_deterministic():
base = [
shelf(),
item(hostname="srv02", mounted_on="shf01", shelf_face="front", shelf_slot=2),
item(hostname="srv01", mounted_on="shf01", shelf_face="front", shelf_slot=1),
]
assert gen_rack.render_svg("rack01", base) == gen_rack.render_svg(
"rack01", list(reversed(base))
)
def test_render_page_lists_mounted_devices():
items = [shelf(),
item(hostname="srv01", mounted_on="shf01",
shelf_face="front", shelf_slot=1)]
page = gen_rack.render_page("rack01", items)
assert "../../hardware/srv01.md" in page
assert "front · shf01/1" in page
assert "U37U46" in page # mounted device shows its shelf's U-range
```
- [ ] **Step 2: Run to verify failure**
Run: `pytest tests/test_gen_rack.py -q`
Expected: FAIL — `test_render_page_lists_mounted_devices` raises `KeyError: 'rack_u'` (occupancy loop has no mounted handling) and the SVG tests fail (`shf01`/occupant boxes not drawn; the shelf is drawn as a generic box so `"shf01 (U37"` is present).
- [ ] **Step 3: Render shelves in `render_svg`**
In `render_svg`, the generic device loop currently reads:
```python
for fm in items:
face = fm.get("rack_face")
if face in ("front", "both"):
draw_device(fm, front_x)
if face in ("rear", "both"):
draw_device(fm, rear_x)
```
Replace it with a version that skips shelves and mounted items:
```python
for fm in items:
if fm.get("kind") == "shelf" or "mounted_on" in fm:
continue
face = fm.get("rack_face")
if face in ("front", "both"):
draw_device(fm, front_x)
if face in ("rear", "both"):
draw_device(fm, rear_x)
```
Then, immediately before the final `p.append("</svg>")` line, add the shelf drawing:
```python
SHELF_STRIP_H = 6
shelves = [i for i in items if i.get("kind") == "shelf"]
mounted = [i for i in items if "mounted_on" in i]
def draw_shelf(fm: dict) -> None:
u = fm["rack_u"]
h = fm["u_height"]
y = u_y(u)
block_h = h * U_H
strip_y = y + block_h - SHELF_STRIP_H
avail_h = block_h - SHELF_STRIP_H
shelf_color = KIND_COLORS.get("shelf", DEFAULT_COLOR)
sname = fm.get("hostname", "?")
for col_x, sface in ((front_x, "front"), (rear_x, "rear")):
occ = sorted(
(m for m in mounted
if m.get("mounted_on") == sname
and m.get("shelf_face") == sface),
key=lambda m: (m.get("shelf_slot", 0), m.get("hostname", "")),
)
n = len(occ)
for idx, m in enumerate(occ):
sub_w = COL_W // n

- [ ] **Step 4: Render mounted devices in the `render_page` occupancy table**
In `render_page`, the occupancy loop currently reads:
```python
for fm in items:
name = fm.get("hostname", "?")
link = f"[{name}](../../hardware/{name}.md)"
face = fm.get("rack_face", "")
if face in ZERO_U_FACES:
urange = "0U"
else:
u = fm["rack_u"]
h = fm["u_height"]
urange = f"U{u}" if h == 1 else f"U{u}U{u + h - 1}"
lines.append(
f"| {urange} | {link} | {fm.get('kind', '')} | {face} "
f"| {fm.get('status', '')} |"
)
```
Replace that whole loop with one that orders mounted devices right after their
shelf and renders their shelf-relative position:
```python
by_host = {fm.get("hostname"): fm for fm in items}
mounted_by_shelf: dict[str, list[dict]] = {}
for fm in items:
if "mounted_on" in fm:
mounted_by_shelf.setdefault(fm["mounted_on"], []).append(fm)
def occ_row(fm: dict) -> str:
name = fm.get("hostname", "?")
link = f"[{name}](../../hardware/{name}.md)"
if "mounted_on" in fm:
target = by_host.get(fm["mounted_on"])
if target and isinstance(target.get("rack_u"), int):
su = target["rack_u"]
sh = target["u_height"]
urange = f"U{su}" if sh == 1 else f"U{su}U{su + sh - 1}"
else:
urange = "—"
face = (
f"{fm.get('shelf_face', '')} · "
f"{fm['mounted_on']}/{fm.get('shelf_slot', '')}"
)
else:
face = fm.get("rack_face", "")
if face in ZERO_U_FACES:
urange = "0U"
else:
u = fm["rack_u"]
h = fm["u_height"]
urange = f"U{u}" if h == 1 else f"U{u}U{u + h - 1}"
return (
f"| {urange} | {link} | {fm.get('kind', '')} | {face} "
f"| {fm.get('status', '')} |"
)
for fm in _sorted_items([i for i in items if "mounted_on" not in i]):
lines.append(occ_row(fm))
if fm.get("kind") == "shelf":
occ = sorted(
mounted_by_shelf.get(fm.get("hostname"), []),
key=lambda m: (m.get("shelf_face", ""), m.get("shelf_slot", 0)),
)
for m in occ:
lines.append(occ_row(m))
```
(The `items = _sorted_items(items)` line at the top of `render_page` and the
graph sections above are unchanged.)
- [ ] **Step 5: Run to verify pass**
Run: `pytest tests/test_gen_rack.py -q`
Expected: PASS (all prior tests + 3 new).
- [ ] **Step 6: Commit**
```bash
git add scripts/gen_rack.py tests/test_gen_rack.py
git commit -m "feat(rack): render shelf strip, occupant boxes, and mounted occupancy rows"
```

### Task 3: Populate the shelf demo, regenerate
**Files:**
- Create: `docs/hardware/shf01.md`
- Modify: `docs/hardware/srv01.md`, `srv02.md`, `srv03.md` (convert to mounted)
- Regenerate: `docs/hardware/index.md`, `docs/infrastructure/racks/rack01.md`, `docs/infrastructure/racks/rack01-elevation.svg`
**Interfaces:**
- Consumes: `make docs-index`, `make test`, `mkdocs build --strict`, `make docs-check`.
> **Operator note — provisional data.** The shelf placement and the front/rear/slot assignments are placeholders matching the worked example (TaPPaaS: srv01/srv02 front, srv03 rear, on a shelf reserving U37U46). `check_shelves`/`check_overlaps` reject inconsistent data loudly.
- [ ] **Step 1: Create the shelf file**
Create `docs/hardware/shf01.md`:
```markdown
---
hostname: shf01
kind: shelf
status: in-use
rack: rack01
rack_u: 37
u_height: 10
rack_face: both
cluster: tappaas
---
## Notes
- Provisional placeholder shelf holding the TaPPaaS nodes (srv01/srv02 front, srv03 rear).
```
- [ ] **Step 2: Convert `srv01.md` to mounted**
In `docs/hardware/srv01.md`, replace these three frontmatter lines:
```yaml
rack_u: 1
u_height: 1
rack_face: front
```
with:
```yaml
mounted_on: shf01
shelf_face: front
shelf_slot: 1
```
Leave everything else (including `cluster: tappaas`, `power:`, `links:`) unchanged.
- [ ] **Step 3: Convert `srv02.md` to mounted and tag its cluster**
In `docs/hardware/srv02.md`, replace these three frontmatter lines:
```yaml
rack_u: 2
u_height: 1
rack_face: front
```
with:
```yaml
mounted_on: shf01
shelf_face: front
shelf_slot: 2
```
Then add a `cluster: tappaas` line immediately after the `status: staging` line, so the top reads:
```yaml
hostname: srv02
kind: server
status: staging
cluster: tappaas
location: The pile
```
- [ ] **Step 4: Convert `srv03.md` to mounted and tag its cluster**
In `docs/hardware/srv03.md`, replace these three frontmatter lines:
```yaml
rack_u: 3
u_height: 1
rack_face: front
```
with:
```yaml
mounted_on: shf01
shelf_face: rear
shelf_slot: 1
```
Then add a `cluster: tappaas` line immediately after the `status: staging` line:
```yaml
hostname: srv03
kind: server
status: staging
cluster: tappaas
location: The pile
```
- [ ] **Step 5: Regenerate all indices and rack artifacts**
Run: `make docs-index`
Expected: `gen_overview.py` rewrites `docs/hardware/index.md` (now listing `shf01` under Shelves); `gen_rack.py` prints `Wrote rack01.md + rack01-elevation.svg (10 item(s))`, exit 0 (no schema error).
- [ ] **Step 6: Confirm the shelf and mounted devices rendered**
Run: `grep -c "shf01/" docs/infrastructure/racks/rack01.md`
Expected: `3` (occupancy notes `front · shf01/1`, `front · shf01/2`, `rear · shf01/1`).
Run: `grep -q "shf01" docs/infrastructure/racks/rack01-elevation.svg && echo OK`
Expected: `OK` (shelf strip drawn).
Run: `grep -q "U37U46" docs/infrastructure/racks/rack01.md && echo OK`
Expected: `OK` (mounted devices show the shelf's U-range).
- [ ] **Step 7: Run the full test suite**
Run: `make test`
Expected: PASS.
- [ ] **Step 8: Build the site strictly**
Run: `mkdocs build --strict` (or `python3 -m mkdocs build --strict` if `mkdocs` is not on PATH)
Expected: build succeeds with no warnings-as-errors.
- [ ] **Step 9: Confirm the drift guard is satisfied**
Run: `make docs-check`
Expected: exit 0.
- [ ] **Step 10: Commit**
```bash
git add docs/hardware/ docs/infrastructure/racks/
git commit -m "feat(rack): place TaPPaaS nodes on shelf shf01 (provisional)"
```

## Self-Review
**Spec coverage (`2026-06-24-rack-shelves-design.md`):**
- Container model: shelf placed + reserves U-range; mounted devices via `mounted_on`/`shelf_face`/`shelf_slot` — Task 1 (validation), Task 3 (data). ✔
- `validate_item` mounted branch (forbid rack_u/u_height/rack_face; require shelf_face/shelf_slot) — Task 1 Step 4. ✔
- `check_overlaps` skips mounted items — Task 1 Step 5. ✔
- `check_shelves` (resolves to placed kind:shelf in rack; unique slot) wired into `generate` — Task 1 Steps 67. ✔
- SVG shelf strip + subdivided occupant boxes — Task 2 Step 3. ✔
- Occupancy rows for mounted devices (shelf U-range + `face · shelf/slot`, ordered after the shelf) — Task 2 Step 4. ✔
- Power/network unchanged — no edits to `render_power`/`render_network`; mounted devices keep `power:`/`links:`. ✔
- Demo data (shf01 U37U46; srv01/srv02 front 12, srv03 rear 1; cluster tappaas) — Task 3. ✔
- No mkdocs/Makefile/CI/overview_config changes — Global Constraints. ✔
**Placeholder scan:** No "TBD"/"handle edge cases"/"similar to Task N". The provisional demo placements are real-data-dependent and explicitly bounded.
**Type consistency:** `SHELF_FACES: set`; `check_shelves(items) -> None` (raises `SchemaError`), called per-rack alongside `check_overlaps`/`validate_power`/`validate_links`; `render_svg`/`render_page` -> `str`. Mounted items are identified uniformly by `"mounted_on" in fm` across `validate_item`, `check_overlaps`, `check_shelves`, `render_svg`, and `render_page`. The `shelf()` test helper (Task 1) is reused in Task 2. Field names (`mounted_on`, `shelf_face`, `shelf_slot`) match across tasks, tests, and demo data.

# Shelf-Mounted Devices Design
**Date:** 2026-06-24
**Status:** Approved
**Parent spec:** `notes/dev/specs/2026-06-24-rack-documentation-design.md` (extension)
## Goal
Let the rack model represent cabinet/tower-style PCs that sit on a rack shelf
rather than bolting into the rails. Several PCs share one shelf, side by side and
front/back, and the assembly spans a tall U-range (e.g. a shelf at U46 with three
towers standing up to U37 = a reserved block U37U46). The current model cannot
express this: two PCs in the same U-range on the same face trip `check_overlaps`.
## Context
- Placement today (`scripts/gen_rack.py`): a rack item declares `rack_u` (lowest
U), `u_height`, and `rack_face` ∈ {front, rear, both, left, right}. `left`/`right`
are 0U side-rail items that omit `rack_u`/`u_height` and attach to a rail.
`check_overlaps` rejects two items sharing a U on the same face; it already
skips 0U rail items.
- This gives a precedent: **some items don't claim a U-range directly** (0U rails
attach to a rail). Shelf-mounted PCs are a third placement style — they attach
to a shelf.
- The physical rack is labeled U1 at the top → U48 at the bottom, so a shelf at
U46 (near the bottom) with towers standing upward to U37 reserves U37U46.
- `shelf` is already a valid `kind` (abbrev `shf`) with a color in `KIND_COLORS`.
## Decisions
### 1. Container model
The **shelf** is the rack-placed item; tower PCs are **contained by** it.
- A shelf (`kind: shelf`) is placed normally: `rack_u`, `u_height`,
`rack_face: both` (full depth). Its `rack_u`/`u_height` **reserve the whole
assembly's U-range** (the shelf plus the towers standing on it), e.g.
`rack_u: 37, u_height: 10`.
- A **mounted device** declares, instead of `rack_u`/`u_height`/`rack_face`:
- `mounted_on: <shelf hostname>` — the shelf it sits on.
- `shelf_face: front | rear` — which side of the shelf.
- `shelf_slot: <integer ≥ 1>` — left-to-right position within that face.
Mounted items still declare `rack: <rack>` (so they load as rack items) and may
carry `cluster:`, `power:`, `links:` unchanged — those key off hostname, not
placement.
No `scripts/overview_config.yml` change: `shelf` and `server` kinds already
exist; `mounted_on`/`shelf_face`/`shelf_slot` are extra fields `gen_overview.py`
ignores and `gen_rack.py` validates.
### 2. Validation (in `gen_rack.py`)
`validate_item` gains a placement branch, checked before the existing rail logic:
- If `mounted_on` is present, the item is **mounted**:
- require `shelf_face ∈ {front, rear}`;
- require `shelf_slot` to be an integer ≥ 1;
- forbid `rack_u`, `u_height`, and `rack_face` (mutually exclusive with
mounting, mirroring the 0U rule).
- Otherwise the existing rules apply unchanged (rail item: `rack_face` ∈ FACES,
0U rules for left/right, U-range for the rest).
`check_overlaps` **skips mounted items** (they claim no U-range; their shelf
reserves the block) — added alongside the existing 0U skip. The shelf itself is
a normal placed item, so it still cannot overlap rail gear.
New `check_shelves(items: list[dict]) -> None` (called per rack from `generate`,
alongside `check_overlaps`/`validate_power`/`validate_links`):
- every `mounted_on` resolves to an item **in the same rack** whose `kind` is
`shelf` and which is itself placed (has integer `rack_u`/`u_height`);
- `(mounted_on, shelf_face, shelf_slot)` is unique — no two devices in the same
spot on the same shelf.
### 3. Rendering (`gen_rack.py`)
**Elevation SVG (`render_svg`):**
- The shelf draws as a thin **shelf strip** (shelf-colored rect) at the bottom 1U
of its reserved U-range, in both columns, labeled with the shelf hostname.
- Mounted occupants draw inside the reserved range, above the strip: for each
face (`front` → front column, `rear` → rear column), gather that shelf's
occupants for that face, order them by `shelf_slot` ascending, and subdivide
the column width by the **number of occupants on that face** — one labeled box
per tower (hostname), drawn side by side. This produces the approved
"two front, one back" picture.
- Determinism: occupants ordered by `(shelf_slot, hostname)`; shelves processed
in hostname order.
**Occupancy table (`render_page`):**
- Mounted devices list the **shelf's U-range** in the U column (e.g. `U37U46`)
and a `\<shelf_face\> · \<mounted_on\>/\<shelf_slot\>` note in the Face column
(e.g. `front · shf01/1`).
- Ordering: rail items by U; each shelf's mounted devices appear immediately
after the shelf, ordered by `(shelf_face, shelf_slot)`; 0U rail items last.
**Power/network graphs:** unchanged — mounted PCs appear by hostname exactly as
rail-mounted devices do.
## Provisional demo data
Applies the worked example to the existing TaPPaaS nodes (user-confirmed):
- New `docs/hardware/shf01.md`: `kind: shelf`, `status: in-use`, `rack: rack01`,
`rack_u: 37`, `u_height: 10`, `rack_face: both`, `cluster: tappaas`.
- `srv01`: drop `rack_u`/`u_height`/`rack_face`; add `mounted_on: shf01`,
`shelf_face: front`, `shelf_slot: 1`. (Keeps `cluster: tappaas`, `power:`,
`links:`.)
- `srv02`: same, `shelf_face: front`, `shelf_slot: 2`; add `cluster: tappaas`.
- `srv03`: same, `shelf_face: rear`, `shelf_slot: 1`; add `cluster: tappaas`.
- `srv04`, `srv05` stay rail-mounted at U5U6 (unchanged). The shelf block
U37U46 does not overlap any existing rail item (sw01 U10, pp01 U24, srv04/05
U5U6, pdu rails).
All placements remain provisional placeholders; `check_shelves`/`check_overlaps`
reject inconsistent data loudly.
## Integration
| File | Change |
|------|--------|
| `scripts/gen_rack.py` | `validate_item` mounted branch; `check_overlaps` skip mounted; new `check_shelves`; `render_svg` shelf strip + subdivided occupant boxes; `render_page` occupancy rows for mounted items |
| `tests/test_gen_rack.py` | mounted-validation, `check_shelves`, SVG, and occupancy cases |
| `docs/hardware/shf01.md` | New shelf file |
| `docs/hardware/srv01.md`..`srv03.md` | Convert to mounted; `srv02`/`srv03` gain `cluster: tappaas` |
| `docs/hardware/index.md`, `docs/infrastructure/racks/rack01.*` | Regenerated |
No `mkdocs.yml`, `Makefile`, `.forgejo/workflows/docs.yml`, or
`overview_config.yml` changes.
## Test plan
- **Unit — `validate_item`:** accept a valid mounted item; reject a mounted item
that also has `rack_u`/`u_height`/`rack_face`, a bad `shelf_face`, or a
non-integer/<1 `shelf_slot`.
- **Unit — `check_overlaps`:** two mounted items sharing their shelf's U-range do
not raise (mounted items are skipped).
- **Unit — `check_shelves`:** accept valid mounts; reject `mounted_on` pointing at
a missing item, at a non-`shelf` kind, or at an unplaced shelf; reject two
occupants sharing `(shelf, face, slot)`.
- **Unit — `render_svg`:** a shelf with two front + one rear occupant produces a
shelf strip and three labeled occupant boxes; front occupants share the front
column side by side; deterministic for reordered input.
- **Unit — `render_page`:** mounted devices appear in the occupancy table with the
shelf's U-range and the `face · shelf/slot` note.
- **Integration — `generate`:** valid fixtures write a page; a dangling
`mounted_on` returns `1` and writes nothing.
- **Drift / visual:** `make docs-check` exits 0; `mkdocs build --strict` renders
the rack page with the shelf block showing srv01/srv02 front and srv03 rear.
## Out of scope
- Shelf capacity limits (max slots per face) — slot-collision detection suffices.
- Modeling individual tower height separately from the shelf's reserved block.
- Nested shelves or shelves spanning racks.
