+ISO image bootable via BMC virtual media or USB. Runs boot services automatically and writes the audit result to `/var/log/bee-audit.json`.
 
 ### 2.1 — Builder environment
 
-`iso/builder/Dockerfile` — Alpine 3.21 build environment with:
-- `alpine-sdk`, `abuild`, `squashfs-tools`, `xorriso`
-- Go toolchain (for binary compilation inside builder)
-- NVIDIA driver `.run` pre-fetched during image build
+`iso/builder/build-in-container.sh` is the only supported builder entrypoint.
+It builds a Debian 12 builder image with `live-build`, toolchains, and pinned kernel headers,
+then runs the ISO assembly in a privileged container because `live-build` needs
+mount/chroot/loop capabilities.
 
-`iso/builder/build.sh` — orchestrates full ISO build:
-1. Compile Go binary (static, `CGO_ENABLED=0`)
-2. Compile NVIDIA kernel module against Alpine 3.21 LTS kernel headers
-3. Run `mkimage.sh` with bee profile
-4. Output: `dist/bee-<version>.iso`
+`iso/builder/build.sh` orchestrates the full ISO build:
+1. compile the Go `bee` binary
+2. create a staged overlay under `dist/overlay-stage`
+3. inject SSH auth, vendor tools, NVIDIA artifacts, and build metadata into the staged overlay
+4. create a disposable `live-build` workdir under `dist/live-build-work`
+5. sync the staged overlay into `config/includes.chroot/`
+6. run `lb config && lb build`
+7. copy the final ISO into `dist/`
 
 ### 2.2 — NVIDIA driver build
 
-Alpine 3.21, LTS kernel 6.6 — fixed versions in builder.
+`iso/builder/build-nvidia-module.sh`:
+- downloads the pinned NVIDIA `.run` installer
+- verifies SHA256
+- builds kernel modules against the pinned Debian kernel ABI
+- caches modules, userspace tools, and libs in `dist/nvidia-<version>-<kver>/`
 
-`iso/builder/build-nvidia.sh`:
-- Download `NVIDIA-Linux-x86_64-<ver>.run` (version pinned in `iso/builder/VERSIONS`)
-- Extract kernel module sources
-- Compile against `linux-lts-dev` headers
-- Strip and package as `nvidia-<ver>-k6.6.ko.tar.gz` for inclusion in overlay
+`iso/overlay/usr/local/bin/bee-nvidia-load`:
+- loads `nvidia`, `nvidia-modeset`, `nvidia-uvm` via `insmod`
+- creates `/dev/nvidia*` nodes if the driver registered successfully
+- logs failures but does not block the rest of boot
 
-`iso/overlay/usr/local/bin/load-nvidia.sh`:
-- `insmod` sequence: nvidia.ko → nvidia-modeset.ko → nvidia-uvm.ko
-- Verify: `nvidia-smi -L` → log result
-- On failure: log warning, continue (audit runs without GPU enrichment)
+### 2.3 — ISO assembly and overlay policy
 
-### 2.3 — Alpine mkimage profile
+`iso/overlay/` is source-only input for the build.
 
-`iso/builder/mkimg.bee.sh` — Alpine mkimage profile:
-- Base: `alpine-base`
-- Kernel: `linux-lts`
-- Packages: `dmidecode smartmontools nvme-cli pciutils ipmitool util-linux e2fsprogs qrencode`
-- Overlay: `iso/overlay/` included as apkovl
+Build-time files are injected into the staged overlay only:
+- `bee`
+- `bee-smoketest`
+- `authorized_keys`
+- password-fallback marker
+- `/etc/bee-release`
+- vendor tools from `iso/vendor/`
 
-### 2.4 — Network bring-up on boot
+The source tree must stay clean after a build.
 
-`iso/overlay/usr/local/bin/bee-network.sh`:
-- Enumerate all network interfaces: `ip link show` → filter out loopback and virtual (docker/bridge)
-- For each physical interface: `ip link set <iface> up` + `udhcpc -i <iface> -t 5 -T 3 -n`
-- Log each interface result (got IP / timeout / no carrier)
-- Continue regardless — network is best-effort for auto-update
+### 2.4 — Boot services
 
-`iso/overlay/etc/init.d/bee-network`:
-- runlevel: default, before: bee-update
-- Calls bee-network.sh
-- Does not block boot if DHCP fails on all interfaces
+`systemd` service order:
+- `bee-sshsetup.service` → configures SSH auth before `ssh.service`
+- `bee-network.service` → starts best-effort DHCP on all physical interfaces
+- `bee-nvidia.service` → loads NVIDIA modules if present
+- `bee-audit.service` → runs audit and logs failures without turning partial collector bugs into a boot blocker
 
-### 2.5 — OpenRC boot service (bee-audit)
+### 2.4b — Runtime split
 
-`iso/overlay/etc/init.d/bee-audit`:
-- runlevel: default, after: bee-update
-- start(): load-nvidia.sh → /usr/local/bin/audit --output usb
-- on completion: print QR summary to /dev/tty1 (always, even if USB write failed)
-- log everything to /var/log/bee-audit.log
-- exits 0 regardless of partial failures — unattended, no prompts, no waits
+Target split:
+- main Go application works on a normal Linux host and on the live ISO
+- live-ISO specifics stay in integration glue under `iso/`
+- the live ISO passes `--runtime livecd` to the Go binary
+- local runs default to `--runtime auto`, which resolves to `local` unless a live marker is detected
 
-Unattended invariants:
-- No TTY prompts ever. All decisions are automatic.
-- Missing USB: output goes to /tmp/bee-audit-<serial>-<date>.json, QR shown on screen.
-- Missing NVIDIA driver: GPU records have status UNKNOWN, audit continues.
-- Missing ipmitool/storcli/any tool: that collector is skipped, rest continue.
-- Timeout on any external command: 30s hard limit via `timeout` wrapper, then skip.
-- Boot never hangs waiting for user input.
+Planned code shape:
+- `audit/cmd/bee/` — main CLI entrypoint
+- `audit/internal/runtimeenv/` — runtime detection and mode selection
+- future `audit/internal/tui/` — host/live shared TUI logic
+- `iso/overlay/` — boot-time livecd integration only
 
-`iso/overlay/etc/runlevels/default/bee-audit` symlink
+### 2.5 — Operator workflows
 
-### 2.6 — Vendor utilities in overlay
+- Automatic boot audit writes JSON to `/var/log/bee-audit.json`
+- `tty1` autologins into `bee` and auto-runs `menu`
+- `menu` launches the LiveCD wrapper `bee-tui`, which escalates to `root` via `sudo -n`
+- `bee tui` can rerun the audit manually
+- `bee tui` can export the latest audit JSON to removable media
+- `bee tui` can show health summary and run NVIDIA/memory/storage acceptance tests
+- NVIDIA SAT now includes a lightweight in-image GPU stress step via `bee-gpu-stress`
+- SAT summaries now expose `overall_status` plus per-job `OK/FAILED/UNSUPPORTED`
+- Memory/GPU SAT runtime defaults can be overridden via `BEE_MEMTESTER_*` and `BEE_GPU_STRESS_*`
+- removable export requires explicit target selection, mount, confirmation, copy, and cleanup
 
-`iso/overlay/usr/local/bin/` includes pre-fetched proprietary tools:
-- `storcli64` (Broadcom)
-- `sas2ircu`, `sas3ircu` (Broadcom/LSI)
-- `mstflint` (NVIDIA Networking / Mellanox)
+### 2.6 — Vendor utilities and optional assets
 
-`scripts/fetch-vendor.sh` — downloads and places these before ISO build.
-Checksums verified. Tools not committed to git — fetched at build time.
+Optional binaries live in `iso/vendor/` and are included when present:
+- `storcli64`
+- `sas2ircu`, `sas3ircu`
+- `arcconf`
+- `ssacli`
+- `mstflint` (via Debian package set)
 
-`iso/vendor/.gitkeep` — placeholder, directory gitignored except .gitkeep
+Missing optional tools do not fail the build or boot.
 
-### 2.7 — Auto-update of audit binary (USB + network)
+### 2.7 — Release workflow
 
-Two update paths, tried in order on every boot:
+`iso/builder/VERSIONS` pins the current release inputs:
+- audit version
+- Debian version / kernel ABI
+- Go version
+- NVIDIA driver version
 
-**Path A — USB (no network required, higher priority):**
-
-`bee-update.sh` scans mounted removable media for an update package before checking network.
-
-Looks for: `<usb>/bee-update/bee-audit-linux-amd64` + `<usb>/bee-update/bee-audit-linux-amd64.sha256`
-
-Steps:
-1. Find USB mount point (same detection as audit output: `/sys/block/*/removable`)
-2. Check for `bee-update/bee-audit-linux-amd64` on the USB root
-3. Read version from `bee-update/VERSION` file (plain text, e.g. `1.3`)
-4. Compare with running binary version (`/usr/local/bin/audit --version`)
-5. If USB version > running: verify SHA256 checksum, replace binary, log update
-6. Re-run audit if updated
-
-**Authenticity verification — Ed25519 multi-key trust (stdlib only, no external tools):**
-
-Problem: SHA256 alone does not prevent a crafted attack — an attacker places their binary
-and a matching SHA256 next to it. The LiveCD would accept it.
-
-Solution: Ed25519 asymmetric signatures via Go stdlib `crypto/ed25519`.
-Multiple developer public keys are supported. A binary update is accepted if its signature
-verifies against ANY of the embedded trusted public keys.
-
-This mirrors the SSH authorized_keys model: add a developer → add their public key.
-Remove a developer → rebuild without their key.
-
-**Key management — centralized across all projects:**
-
-Public keys live in a dedicated repo at git.mchus.pro/mchus/keys (or similar):
-```
-keys/
-  developers/
-    mchusavitin.pub    ← Ed25519 public key, base64, one line
-    developer2.pub
-  README.md            ← how to generate a key pair
-```
-
-Public keys are safe to commit — they are not secret.
-Private keys stay on each developer's machine, never committed anywhere.
-
-Key generation (one-time per developer, run locally):
-```sh
-# scripts/keygen.sh — also lives in the keys repo
-openssl genpkey -algorithm ed25519 -out ~/.bee-release.key
-openssl pkey -in ~/.bee-release.key -pubout -outform DER \
-  | tail -c 32 | base64 > mchusavitin.pub
-```
-
-**Embedding public keys at release time (not compile time):**
-
-Public keys are injected via `-ldflags` at build time from the keys repo.
-The binary does not hardcode keys — they are provided by the release script.
-
-```go
-// audit/internal/updater/trust.go
-// trustedKeysRaw is injected at build time via -ldflags
-// format: base64(key1):base64(key2):...
-var trustedKeysRaw string
-
-func trustedKeys() ([]ed25519.PublicKey, error) {
-    if trustedKeysRaw == "" {
-        return nil, fmt.Errorf("binary built without trusted keys — updates disabled")
-    }
-    var keys []ed25519.PublicKey
-    for _, enc := range strings.Split(trustedKeysRaw, ":") {
-        b, err := base64.StdEncoding.DecodeString(strings.TrimSpace(enc))
-        if err != nil || len(b) != ed25519.PublicKeySize {
-            return nil, fmt.Errorf("invalid trusted key: %w", err)
-        }
-        keys = append(keys, ed25519.PublicKey(b))
-    }
-    return keys, nil
-}
-
-func verifySignature(binaryPath, sigPath string) error {
-    keys, err := trustedKeys()
-    if err != nil {
-        return err
-    }
-    data, _ := os.ReadFile(binaryPath)
-    sig, _ := os.ReadFile(sigPath)  // 64 bytes raw Ed25519 signature
-    for _, key := range keys {
-        if ed25519.Verify(key, data, sig) {
-            return nil  // any trusted key accepts → pass
-        }
-    }
-    return fmt.Errorf("signature verification failed: no trusted key matched")
-}
-```
-
-Release build injects keys:
-```sh
-# scripts/build-release.sh
-KEYS=$(paste -sd: keys/developers/*.pub)
-go build -ldflags "-X bee/audit/internal/updater/trust.trustedKeysRaw=${KEYS}" \
-  -o dist/bee-audit-linux-amd64 ./cmd/audit
-```
-
-Signing (release engineer signs with their private key):
-```sh
-# scripts/sign-release.sh <binary>
-openssl pkeyutl -sign -inkey ~/.bee-release.key \
-  -rawin -in "$1" -out "$1.sig"
-```
-
-Binary built without `-ldflags` injection (e.g. local dev build) has `trustedKeysRaw=""`
-→ updates are disabled, logged as INFO, audit continues normally.
-
-Update rejected silently (logged as WARNING, audit continues with current binary) if:
-- `.sig` file missing
-- Signature does not match any trusted key
-- `trustedKeysRaw` empty (dev build)
-
-Update package layout on USB:
-```
-/bee-update/
-  bee-audit-linux-amd64        ← new binary (also signed with embedded keys)
-  bee-audit-linux-amd64.sig    ← Ed25519 signature (64 bytes raw)
-  VERSION                      ← plain version string e.g. "1.3"
-```
-
-Admin workflow: download `bee-audit-linux-amd64` + `bee-audit-linux-amd64.sig` from Gitea
-release assets, place in `bee-update/` on USB.
-
-**Path B — Network (requires DHCP on at least one interface):**
-1. Check network: ping git.mchus.pro -c 1 -W 3 || skip
-2. Fetch: `GET https://git.mchus.pro/api/v1/repos/<org>/bee/releases/latest`
-3. Parse tag_name, asset URLs for `bee-audit-linux-amd64` + `bee-audit-linux-amd64.sig`
-4. Compare tag with running version
-5. If newer: download both files to /tmp, verify Ed25519 signature against all trusted keys
-6. Replace binary on pass, log and skip on fail
-7. Re-run audit if updated
-
-**Ordering:** USB update checked first, network checked second.
-If USB update applied and verified, network check is skipped.
-
-`iso/overlay/etc/init.d/bee-update`:
-- runlevel: default
-- after: bee-network (network path needs interfaces up)
-- before: bee-audit (audit runs with latest binary)
-- Calls bee-update.sh
-
-Triggered after bee-audit completes, only if network is available.

+# Charting architecture
+
+## Decision: one chart engine for all live metrics
+
+**Engine:** `github.com/go-analyze/charts` (pure Go, no CGO, SVG output)
+**Theme:** `grafana` (dark background, coloured lines)
+
+All live metrics charts in the web UI are server-side SVG images served by Go
+and polled by the browser every 2 seconds via `<img src="...?t=now">`.
+There is no client-side canvas or JS chart library.
+
+### Why go-analyze/charts
+
+- Pure Go, no CGO — builds cleanly inside the live-build container
+- SVG output — crisp at any display resolution, full-width without pixelation
+- Grafana theme matches the dark web UI colour scheme
+- Active fork of the archived wcharczuk/go-chart
+
+### SAT stress-test charts
+
+The `drawGPUChartSVG` function in `platform/gpu_metrics.go` is a separate
+self-contained SVG renderer used **only** for completed SAT run reports
+(HTML export, burn-in summaries). It is not used for live metrics.
+
+### Live metrics chart endpoints
+
+| Path | Content |
+|------|---------|
+| `GET /api/metrics/chart/server.svg` | CPU temp, CPU load %, mem load %, power W, fan RPMs |
+| `GET /api/metrics/chart/gpu/{idx}.svg` | GPU temp °C, load %, mem %, power W |
+
+Charts are 1400 × 280 px SVG. The page renders them at `width: 100%` in a
+single-column layout so they always fill the viewport width.
+
+### Ring buffers
+
+Each metric is stored in a 120-sample ring buffer (2 minutes of history at 1 Hz).
+Buffers are per-server or per-GPU and grow dynamically as new GPUs appear.

+The live system is expected to boot with `toram`, so `live-boot` copies the full read-only medium into RAM before mounting the root filesystem. After that point, runtime must not depend on the original USB/BMC virtual media staying readable.
+
+`systemd` boot order:
 
 ```
-localmount
-  ├── bee-sshsetup   (creates bee user, sets password; runs before dropbear)
-  │     └── dropbear  (SSH on port 22 — starts without network)
-  ├── bee-network    (udhcpc -b on all physical interfaces, non-blocking)
-  │     └── bee-nvidia  (insmod nvidia*.ko from /usr/local/lib/nvidia/,
-  │                      creates libnvidia-ml.so.1 symlinks in /usr/lib/)
-  │           └── bee-audit  (runs audit binary → /var/log/bee-audit.json)
+local-fs.target
+  ├── bee-sshsetup.service   (enables SSH key auth; password fallback only if marker exists)
+  │     └── ssh.service      (OpenSSH on port 22 — starts without network)
+  ├── bee-network.service    (starts `dhclient -nw` on all physical interfaces, non-blocking)
+  ├── bee-nvidia.service     (insmod nvidia*.ko from /usr/local/lib/nvidia/,
+  │                           creates /dev/nvidia* nodes)
+  ├── bee-audit.service      (runs `bee audit` → /var/log/bee-audit.json,
+  │                            never blocks boot on partial collector failures)
+  ├── bee-web.service        (runs `bee web` on :80 — full interactive web UI)
+  └── bee-desktop.service    (startx → openbox + chromium http://localhost/)
 ```
 
 **Critical invariants:**
-- Dropbear MUST start without network. `bee-sshsetup` has `need localmount` only.
-- `bee-network` uses `udhcpc -b` (background) — retries indefinitely if no cable.
-- `bee-nvidia` loads modules via `insmod` with absolute paths — NOT `modprobe`.
-  Reason: modloop squashfs mounts over `/lib/modules/<kver>/` at boot, making it
-  read-only. The overlay's modules at that path are inaccessible. Modules are stored
-  at `/usr/local/lib/nvidia/` (overlay path, always writable).
-- `bee-nvidia` creates `libnvidia-ml.so.1` symlinks in `/usr/lib/` — required because
-  `nvidia-smi` is a glibc binary that looks for the soname symlink, not the versioned file.
-- `gcompat` package provides `/lib64/ld-linux-x86-64.so.2` for glibc compat on Alpine musl.
-- `bee-audit` uses `after bee-nvidia` — ensures NVIDIA enrichment succeeds.
-- `bee-audit` uses `eend 0` always — never fails boot even if audit errors.
+- The live ISO boots with `boot=live toram`. Runtime binaries must continue working even if the original boot media disappears after early boot.
+- OpenSSH MUST start without network. `bee-sshsetup.service` runs before `ssh.service`.
+- `bee-network.service` uses `dhclient -nw` (background) — network bring-up is best effort and non-blocking.
+- `bee-nvidia.service` loads modules via `insmod` with absolute paths — NOT `modprobe`.
+  Reason: the modules are shipped in the ISO overlay under `/usr/local/lib/nvidia/`, not in the host module tree.
+- `bee-audit.service` does not wait for `network-online.target`; audit is local and must run even if DHCP is broken.
+- `bee-audit.service` logs audit failures but does not turn partial collector problems into a boot blocker.
+- `bee-web.service` binds `0.0.0.0:80` and always renders the current `/var/log/bee-audit.json` contents.
+- Audit JSON now includes a `hardware.summary` block with overall verdict and warning/failure counts.

+Build host notes:
+- `build-in-container.sh` targets `linux/amd64` builder containers by default, including Docker Desktop on macOS / Apple Silicon.
+- Override with `BEE_BUILDER_PLATFORM=<os/arch>` only if you intentionally need a different container platform.
+- If the local builder image under the same tag was previously built for the wrong architecture, the script rebuilds it automatically.
+
 **Critical invariants:**
-- `KERNEL_PKG_VERSION` in `iso/builder/VERSIONS` pins the exact Alpine package version
-  (e.g. `6.12.76-r0`). This version is used in THREE places that MUST stay in sync:
-  1. `build-nvidia-module.sh` — `apk add linux-lts-dev=${KERNEL_PKG_VERSION}` (compile headers)
-  2. `mkimg.bee.sh` — `linux-lts=${KERNEL_PKG_VERSION}` in apks list (ISO kernel)
-  3. `build.sh` — build-time verification that headers match pin (fails loudly if not)
-  When Alpine releases a new linux-lts patch (e.g. r0 → r1), update KERNEL_PKG_VERSION
-  in VERSIONS — that's the only place to change. The build will fail loudly if the pin
-  doesn't match the installed headers, so stale pins are caught immediately.
-- **All three must use the same APK mirror: `dl-cdn.alpinelinux.org`.** Both
-  `build-nvidia-module.sh` (apk add) and `mkimage.sh` (--repository) explicitly use
-  `https://dl-cdn.alpinelinux.org/alpine/v${ALPINE_VERSION}/main|community`.
-  Never use the builder's local `/etc/apk/repositories` — its mirror may serve
-  a different package state, causing "unable to select package" failures.
-- `linux-lts-dev` is always installed (not conditional) — stale 6.6.x headers on the
-  builder would cause modules to be built for the wrong kernel and never load at runtime.
-- NVIDIA modules go to `overlay/usr/local/lib/nvidia/` — NOT `lib/modules/<kver>/extra/`.
-- `genapkovl-bee.sh` must be copied to `/var/tmp/` (CWD when mkimage runs).
-- `TMPDIR=/var/tmp` required — tmpfs `/tmp` is only ~1GB, too small for kernel firmware.
-- Workdir cleanup preserves `apks_*`, `kernel_*`, `syslinux_*`, `grub_*` cache dirs.

-## gpu_burn vendor binary
-
-`gpu_burn` requires CUDA nvcc to build. It is NOT built as part of the main ISO build.
-Build separately on the builder VM and place in `iso/vendor/gpu_burn`:
-
-```sh
-sh iso/builder/build-gpu-burn.sh dist/
-cp dist/gpu_burn iso/vendor/gpu_burn
-cp dist/compare.ptx iso/vendor/compare.ptx
-```
-
-Requires: CUDA 12.8+ (supports GCC 14, Alpine 3.21), libxml2, g++, make, git.
-The `build.sh` will include it automatically if `iso/vendor/gpu_burn` exists.
+- `DEBIAN_KERNEL_ABI` in `iso/builder/VERSIONS` pins the exact kernel ABI used in BOTH places:
+  1. `build-in-container.sh` / `build-nvidia-module.sh` — Debian kernel headers for module build
+  2. `auto/config` — `linux-image-${DEBIAN_KERNEL_ABI}` in the ISO
+- NVIDIA modules go to staged `usr/local/lib/nvidia/` — NOT to `/lib/modules/<kver>/extra/`.
+- `bee-gpu-stress` must be built against cached CUDA userspace headers from `build-cublas.sh`, not against random host-installed CUDA headers.
+- The live ISO must ship `libcublas`, `libcublasLt`, and `libcudart` together with `libcuda` so tensor-core stress works without internet or package installs at boot.
+- The source overlay in `iso/overlay/` is treated as immutable source. Build-time files are injected only into the staged overlay.
+- The live-build workdir under `dist/` is disposable; source files under `iso/builder/` stay clean.
+- Container build requires `--privileged` because `live-build` uses mounts/chroots/loop devices during ISO assembly.
+- On macOS / Docker Desktop, the builder still must run as `linux/amd64` so the shipped ISO binaries remain `amd64`.
+- Operators must provision enough RAM to hold the full compressed live medium plus normal runtime overhead, because `toram` copies the entire read-only ISO payload into memory before the system reaches steady state.

 # Backlog
 
-## GPU stress test (H100)
+## BMC версия через IPMI
 
-**Задача:** добавить GPU burn/stress тест в bee-tui без существенного увеличения ISO.
+**Статус:** реализовано.
 
-**Контекст:**
-- `gpu_burn` (wilicc/gpu-burn) не подходит — требует `libcublas.so` (~500MB), что раздует ISO кратно
-- `libcuda.so` уже есть в ISO (из NVIDIA .run installer)
+Добавить сбор версии BMC firmware в board collector:
+- Команда: `ipmitool mc info` → поле `Firmware Revision`
+- Записывать в `hardware.firmware[]` как `{device_name: "BMC", version: "..."}`
+- Показывать в TUI правой колонке рядом с BIOS версией
+- Graceful skip если `/dev/ipmi0` отсутствует (silent: same pattern as PSU collector)
 
-**Выбранный подход:** написать минимальный стресс-тул на CUDA Driver API
-- Использует только `libcuda.so` (уже в ISO) — никаких новых зависимостей
-- Реализует матричное умножение или memory bandwidth через `cuLaunchKernel`
-- Бинарь ~100KB, компилируется через `nvcc` на builder VM, кладётся в `iso/vendor/`
-- bee-tui вызывает его вместо `gpu_burn`
+## CPU acceptance test через stress-ng
 
-**Отклонённые варианты:**
-- `gpu_burn` — нужен libcublas (~500MB)
-- `nvbandwidth` — только bandwidth, не жжёт FLOPs; нужен libcudart (~8MB)
-- DCGM diag — правильный инструмент для H100 но ~100MB установка
-- Download on demand — нужен libcublas, проблема та же
+**Статус:** реализовано. CPU в Health Check получает PASS/FAIL из summary.txt.
+
+Добавить CPU SAT на базе `stress-ng`:
+- Bake `stress-ng` в ISO (добавить в `bee.list.chroot`)
+- Новый `bee sat cpu` — запускает `stress-ng --cpu 0 --cpu-method all --timeout <N>` где N = duration из режима (Quick=60s, Standard=300s, Express=900s)
+- Параллельно снимает температуры через `sensors` и throttle-флаги из аудит JSON
+- Результат: SAT архив с summary.txt в формате других SAT (overall_status=OK/FAILED)
+- После реализации: CPU в Health Check получает реальный PASS/FAIL статус
+
+## Real hardware validation
+
+**Статус:** ожидает доступа к железу.
+
+Что осталось подтвердить на практике:
+- `bee sat nvidia` на реальном NVIDIA GPU host
+- `bee sat storage` на NVMe/SATA/RAID host
+- `ipmitool sdr` parsing на сервере с реальным BMC/IPMI
+- vendor RAID tooling (`storcli64`, `sas2ircu`, `sas3ircu`, `arcconf`, `ssacli`) в живом ISO
+
+## SAT result polish
+
+**Статус:** частично закрыто.
+
+Что ещё можно улучшить после полевой проверки:
+- точнее классифицировать vendor-specific self-test outputs в `storage SAT`
+- подобрать дефолты `memtester` по объёму RAM на целевых машинах
+- при необходимости расширить `bee-gpu-stress` по длительности/нагрузке
+
+## Hardware Contract backlog
+
+**Статус:** уточнён, сокращён до `bee`-only snapshot scope.
+
+### Не backlog для `bee`
+
+Эти задачи не должны реализовываться в `bee`, потому что относятся к централизованному ingest/lifecycle слою:
+- `status_history`
+- `status_changed_at`
+- определение замены компонента между snapshot'ами
+- timeline/lifecycle/history по diff между экспортами
+
+`bee` отвечает только за текущий snapshot железа и `status_checked_at`.
+
+### Реализуемо инкрементально
+
+Эти поля можно развивать дальше по мере появления реальных sample outputs и vendor-specific parser'ов:
+- `cpus.correctable_error_count`
+- `cpus.uncorrectable_error_count`
+- `power_supplies.life_remaining_pct`
+- `power_supplies.life_used_pct`
+- `pcie_devices.battery_charge_pct`
+- `pcie_devices.battery_health_pct`
+- `pcie_devices.battery_temperature_c`
+- `pcie_devices.battery_voltage_v`
+- `pcie_devices.battery_replace_required`
+
+### Vendor/platform-specific, часто пустые
+
+Эти поля допустимо оставлять пустыми на части платформ даже после реализации parser'ов:
+- `power_supplies.life_remaining_pct`
+- `power_supplies.life_used_pct`
+- часть `pcie_devices.battery_*` для неподдержанных RAID/NIC/GPU вендоров
+
+### Unsupported в `bee`
+
+Эти поля считаются нереалистичными для общего OS-level hardware snapshotter без synthetic/fake data:
+- `cpus.life_remaining_pct`
+- `cpus.life_used_pct`
+- `memory.life_remaining_pct`
+- `memory.life_used_pct`
+- `memory.spare_blocks_remaining_pct`
+- `memory.performance_degraded`
+
+Причина: у обычного Linux-host audit обычно нет честного vendor-neutral runtime source для этих метрик.
+
+Эти поля считаются дропнутыми из backlog `bee` и не должны возвращаться в план работ без появления нового доказуемого локального источника данных на целевых машинах.

+
+## Принципы
+
+1. **Snapshot** — JSON описывает состояние сервера на момент сбора. Может включать историю изменений статуса компонентов.
+2. **Идемпотентность** — повторная отправка идентичного payload не создаёт дублей (дедупликация по хешу).
+3. **Частичность** — можно передавать только те секции, данные по которым доступны. Пустой массив и отсутствие секции эквивалентны.
+4. **Строгая схема** — endpoint использует строгий JSON-декодер; неизвестные поля приводят к `400 Bad Request`.
+5. **Event-driven** — импорт создаёт события в timeline (LOG_COLLECTED, INSTALLED, REMOVED, FIRMWARE_CHANGED и др.).
+6. **Без синтеза со стороны интегратора** — сборщик передаёт только фактически собранные значения. Нельзя придумывать `serial_number`, `component_ref`, `message`, `message_id` или другие идентификаторы/атрибуты, если источник их не предоставил или парсер не смог их надёжно извлечь.
+

+
+## Endpoint
+
+```
+POST /ingest/hardware
+Content-Type: application/json
+```
+
+**Ответ при приёме (202 Accepted):**
+```json
+{
+  "status": "accepted",
+  "job_id": "job_01J..."
+}
+```
+
+Импорт выполняется асинхронно. Результат доступен по:
+```
+GET /ingest/hardware/jobs/{job_id}
+```
+
+**Ответ при успехе задачи:**
+```json
+{
+  "status": "success",
+  "bundle_id": "lb_01J...",
+  "asset_id": "mach_01J...",
+  "collected_at": "2026-02-10T15:30:00Z",
+  "duplicate": false,
+  "summary": {
+    "parts_observed": 15,
+    "parts_created": 2,
+    "parts_updated": 13,
+    "installations_created": 2,
+    "installations_closed": 1,
+    "timeline_events_created": 9,
+    "failure_events_created": 1
+  }
+}
+```
+
+**Ответ при дубликате:**
+```json
+{
+  "status": "success",
+  "duplicate": true,
+  "message": "LogBundle with this content hash already exists"
+}
+```
+
+**Ответ при ошибке (400 Bad Request):**
+```json
+{
+  "status": "error",
+  "error": "validation_failed",
+  "details": {
+    "field": "hardware.board.serial_number",
+    "message": "serial_number is required"
+  }
+}
+```
+
+Частые причины `400`:
+- Неверный формат `collected_at` (требуется RFC3339).
+- Пустой `hardware.board.serial_number`.
+- Наличие неизвестного JSON-поля на любом уровне.
+- Тело запроса превышает допустимый размер.

+
+| Поле | Тип | Описание |
+|------|-----|----------|

+- Не включайте записи `status_history` без `changed_at`.
+- Все даты — RFC3339, рекомендуется UTC (`Z`).
+- `manufactured_year_week` используйте, когда источник знает только год и неделю производства, без точной календарной даты.

+| Memory | Компонент игнорируется |
+| Storage | Компонент игнорируется |
+| PSU | Компонент игнорируется |

+# ISO Build Rules
+
+## Verify package names before use
+
+ISO builds take 30–60 minutes. A wrong package name wastes an entire build cycle.
+
+**Rule: before adding any Debian package name to the ISO config, verify it exists and check its file list.**
+
+Use one of:
+- `https://packages.debian.org/bookworm/<package-name>` — existence + description
+- `https://packages.debian.org/bookworm/amd64/<package-name>/filelist` — exact files installed
+- `apt-cache show <package>` inside a Debian bookworm container
+
+This applies to:
+- `iso/builder/config/package-lists/*.list.chroot`
+- Any package referenced in `grub.cfg`, hooks, or overlay scripts (e.g. file paths like `/boot/memtest86+x64.bin`)
+
+## Example of what goes wrong without this
+
+`memtest86+` in Debian bookworm installs `/boot/memtest86+x64.bin`, not `/boot/memtest86+.bin`.
+Guessing the filename caused a broken GRUB entry that only surfaced at boot time, after a full rebuild.

+# Validate vs Burn: Hardware Impact Policy
+
+## Validate Tests (non-destructive)
+
+Tests on the **Validate** page are purely diagnostic. They:
+
+- **Do not write to disks** — no data is written to storage devices; SMART counters (power-on hours, load cycle count, reallocated sectors) are not incremented.
+- **Do not run sustained high load** — commands complete quickly (seconds to minutes) and do not push hardware to thermal or electrical limits.
+- **Do not increment hardware wear counters** — GPU memory ECC counters, NVMe wear leveling counters, and similar endurance metrics are unaffected.
+- **Are safe to run repeatedly** — on new, production-bound, or already-deployed hardware without concern for reducing lifespan.
+
+### What Validate tests actually do
+
+| Test | What it runs |
+|---|---|
+| NVIDIA GPU | `nvidia-smi`, `dcgmi diag` (levels 1–4 read-only diagnostics) |
+| Memory | `memtester` on a limited allocation; reads/writes to RAM only |
+| Storage | `smartctl -a`, `nvme smart-log` — reads SMART data only |
+| CPU | `stress-ng` for a bounded duration; CPU-only, no I/O |
+| AMD GPU | `rocm-smi --showallinfo`, `dmidecode` — read-only queries |
+
+## Burn Tests (hardware wear)
+
+Tests on the **Burn** page run hardware at maximum or near-maximum load for extended durations. They:
+
+- **Wear storage**: write-intensive patterns can reduce SSD endurance (P/E cycles).
+- **Stress GPU memory**: extended ECC stress tests may surface latent defects but also exercise memory cells.
+- **Accelerate thermal cycling**: repeated heat/cool cycles degrade solder joints and capacitors over time.
+- **May increment wear counters**: GPU power-on hours, NVMe media wear indicator, and similar metrics will advance.
+
+### Rule
+
+> Run **Validate** freely on any server, at any time, before or after deployment.
+> Run **Burn** only when explicitly required (e.g., initial acceptance after repair, or per customer SLA).
+> Document when and why Burn tests were run.

+# ISO Build
+
+`bee` ISO is built inside a Debian 12 builder container via `iso/builder/build-in-container.sh`.
+
+## Requirements
+
+- Docker Desktop or another Docker-compatible container runtime
+- Privileged containers enabled
+- Enough free disk space for builder cache, Debian live-build artifacts, NVIDIA driver cache, and CUDA userspace packages
+
+## Build On macOS
+
+From the repository root:
+
+```sh
+sh iso/builder/build-in-container.sh
+```
+
+The script defaults to `linux/amd64` builder containers, so it works on:
+
+- Intel Mac
+- Apple Silicon (`M1` / `M2` / `M3` / `M4`) via Docker Desktop's Linux VM
+
+You do not need to pass `--platform` manually for normal ISO builds.
+
+## Useful Options
+
+Build with explicit SSH keys baked into the ISO:
+
+```sh
+sh iso/builder/build-in-container.sh --authorized-keys ~/.ssh/id_ed25519.pub
+```
+
+Rebuild the builder image:
+
+```sh
+sh iso/builder/build-in-container.sh --rebuild-image
+```
+
+Use a custom cache directory:
+
+```sh
+sh iso/builder/build-in-container.sh --cache-dir /path/to/cache
+```
+
+## Notes
+
+- The builder image is automatically rebuilt if the local tag exists for the wrong architecture.
+- The live ISO boots with Debian `live-boot` `toram`, so the read-only medium is copied into RAM during boot and the runtime no longer depends on the original USB/BMC virtual media staying present.
+- Target systems need enough RAM for the full compressed live medium plus normal runtime overhead, or boot may fail before reaching the TUI.
+- Override the container platform only if you know why:
+
+```sh
+BEE_BUILDER_PLATFORM=linux/amd64 sh iso/builder/build-in-container.sh
+```
+
+- The shipped ISO is still `amd64`.
+- Output ISO artifacts are written under `dist/`.
