_detect_nvidia parsed nvidia-smi --query-gpu=memory.total,name and did
float(memory.total) per row, dropping the row on ValueError. Grace Blackwell
GB10 (DGX Spark, sm_121) reports memory.total as '[N/A]'/'Not Supported'
because the GPU shares the system LPDDR pool rather than carrying discrete VRAM
— so the only GPU row was dropped and a real GB10 (even with vLLM running on it)
was reported as 'No GPU', breaking Cookbook recommendations and model switching.
Keep a named device whose memory.total is non-numeric: when there are no
discrete-VRAM rows but such unified devices exist, report a unified-memory CUDA
GPU backed by the system RAM pool (has_gpu, name, backend=cuda, count,
unified_memory=True) — mirroring how Apple Silicon and AMD APUs are already
handled. Discrete GPUs are unchanged, and a box with a real discrete GPU keeps
the discrete path.
Adds tests/test_hwfit_unified_nvidia.py with a GB10 nvidia-smi fixture: the
device is detected (not dropped), surfaces through detect_system with
unified_memory propagated, discrete GPUs stay non-unified, and a discrete GPU
takes precedence over an N/A-memory row.

POST /api/skills/{id}/markdown set sk.name = slugify(sk.name or match['name']),
taking the name parsed from the edited markdown frontmatter. A changed name
makes update_skill() move the skill directory on disk and re-key its usage
sidecar, orphaning the original id. The UI still holds that original id, so the
next DELETE /api/skills/{id} fails the name/id lookup and 404s — 'can't delete
them now'.
The audit save path (_apply_skill_md) already guards against exactly this with
sk.name = name and an explicit 'must NEVER rename the skill' comment. Apply the
same pin here: keep the stored name on markdown save (content edits still take
effect; only the rename is suppressed). Drops the now-unused slugify import.
Adds tests/test_skill_save_no_rename.py: saving markdown whose frontmatter
renames the skill keeps the original name and applies the edit, and a
subsequent delete-by-original-id succeeds. Pure unit test — calls the route
handlers directly with a mock Request (no server/network), like
test_skills_delete_owner.py.

The Cookbook's manual hardware simulator ("what if I had this setup") let users
pick a backend, but _apply_manual_hardware only accepted cuda/rocm/cpu_x86/
cpu_arm and silently coerced anything else to cuda. So selecting Apple/Metal
simulated a CUDA box instead — and ranked safetensors-only repos a Mac can't
serve, even though the rest of hwfit (services.hwfit.fit, the serve-command
generation) already supports Metal as GGUF-only via llama.cpp/Ollama.
Add "metal" to the accepted backends (now a named _MANUAL_BACKENDS set, kept a
subset of what fit.py understands) and set unified_memory=True for it — Apple
Silicon shares one memory pool with the GPU — while clearing that flag for the
discrete (cuda/rocm) and CPU backends. _apply_manual_hardware is lifted to
module scope so it is directly unit-testable; both route call sites are
unchanged.
Adds tests/test_hwfit_manual_backend.py, including an end-to-end check that a
simulated Metal box only recommends GGUF-servable models.

The Cookbook → Dependencies tab reported llama-cpp-python[server] as "not
installed" even when it was installed and usable for serving. The local check
looked up distribution metadata as pkg["name"].replace("_", "-") — for the
import name `llama_cpp` that yields "llama-cpp", but the module ships in the
`llama-cpp-python` distribution. importlib.metadata.version("llama-cpp") then
raised PackageNotFoundError and the package was marked missing (the import
itself succeeds, which is why serving still worked).
Derive the distribution name from the package's declared pip spec instead
(stripping [extras] and version markers), falling back to the munged import
name only when no pip spec is declared. New _pip_dist_name() helper.
Adds tests/test_cookbook_package_detection.py covering the llama_cpp mapping,
extras/marker stripping, plain names, the no-pip-spec fallback, and that the
route wires the helper in (guarding against the exact regression).
A session that exists only in the in-memory SessionManager — never persisted,
or whose DB row was removed out-of-band — was listed by GET /api/sessions (the
list is built from the in-memory manager) but 404'd on every per-session
operation, so it could never be deleted.
Two causes, both fixed:
1. _verify_session_owner() only consulted the DB and raised 404 when no row
existed. It now falls back to the in-memory session's owner when (and only
when) a session_manager is supplied and the caller actually owns the ghost.
The DB row stays authoritative when present, and a ghost owned by another
user still 404s, so the ownership/security model is unchanged. The new
parameter defaults to None, preserving behavior for all other callers.
2. SessionManager.delete_session() only removed the in-memory entry when a DB
row was found, so memory-only ghosts survived. It now drops the in-memory
copy regardless and reports success when either the DB row or the in-memory
entry was removed.
Added tests/test_session_ghost_delete.py covering both layers, including the
cross-owner 404, the unauthenticated 403, DB-row-wins precedence, and backward
compatibility when no manager is passed.

Self-hosted endpoints on a LAN are sometimes protected by an API key. The admin
"Local" add/test form only sent base_url (+ model_type), so such an endpoint
could not be added — it just errored out — even though the backend
POST /api/model-endpoints and /model-endpoints/test already accept an optional
api_key form field (the cloud "API" form already uses it).
Adds an optional masked "API key" input (adm-epLocalApiKey) to the Local form
and wires it into the local Test and Add handlers, sending api_key only when
filled (an empty value is omitted so we never send a blank Bearer). The field
is cleared after a successful add, matching the cloud form.
Tested: tests/test_local_endpoint_api_key_js.py extracts the two click handlers
and runs them under node with mocked DOM/FormData/fetch, asserting api_key is
sent when the field is filled and omitted when blank, plus that the input
exists as a password field. `node --check static/js/admin.js` passes.
