+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## What this is
+
+A collection of Matter commissioning QR decoders (the `MT:` URI format used by
+Matter/CHIP devices). Users either paste an `MT:` URI or scan a QR code; the
+result shows the decoded payload (version, vendor/product IDs, commissioning
+flow, discovery capabilities, discriminator, passcode). Three artifacts:
+
+- `matter-qr-decoder.html` — the single-file browser app (Vue 3 + Bootstrap).
+- `matter-decode.sh` — a pure-bash CLI port of the same decode logic (no camera
+  scanning; takes a URI as an argument or on stdin).
+- `manufacturers.tsv` — `vendor ID → name` table (~900 rows), shared by both
+  tools and optional (a missing file only drops the vendor-name lookup).
+- `gen-manufacturers.py` — Python 3 stdlib script that regenerates
+   `manufacturers.tsv`. Default source is the upstream `manufacturers.xml`
+   **fetched over the network** (via `curl`; a GitHub `blob/` URL is auto-rewritten
+   to its `raw.githubusercontent.com` form). A positional arg overrides with
+   another URL or a local XML file; passing `matter-qr-decoder.html` uses the
+   embedded `<map>` block as an offline fallback. Reproduces the committed TSV
+   byte-for-byte.
+- `README.md` — user-facing docs; this file documents the internals.
+
+## Commands
+
+There is **no build, test, lint, or package step** — this is not a git repo and has no
+`package.json`. The entire app is one HTML file that runs in the browser:
+
+- Run/develop: open `matter-qr-decoder.html` in a modern browser and edit it directly.
+- Camera scanning (`getUserMedia`) requires a **secure context** — serve over HTTPS or
+  `localhost` (e.g. `python3 -m http.server` then open `http://localhost:8000`).
+- The "Scan QR" feature uses the `BarcodeDetector` API, which is **Chromium-only**
+  (Chrome/Edge). Firefox/Safari fall back to a "not supported" message; paste-input works everywhere.
+- The page loads Vue 3, Bootstrap 5.3, and Bootstrap Icons from CDNs, so it needs network access.
+
+## Architecture
+
+Everything lives in `matter-qr-decoder.html` (~1500 lines). Two regions matter:
+
+1. **App logic** (the `<script>` before `#app` is mounted, ~lines 255-559): a single
+   `Vue.createApp({...})` mounted to `#app`, with all state in `setup()` via `ref`/`computed`.
+   The UI template (lines ~26-253) is plain HTML using `v-model`/`v-if`/`v-on` bindings,
+   no SFC or build step.
+2. **Vendor map** (`<script type="text/xml">`, ~lines 560-1495): a `<map>` of
+   `<mapping code="0xXXXX" translation="Name"/>` entries. This block is the bulk of the
+   file. It is **derived from upstream**
+   `project-chip/connectedhomeip .../zcl/data-model/manufacturers.xml` (Apache-2.0,
+   generated 2022-08-02) and carries an "do not edit manually" note — refresh it from
+   upstream rather than hand-editing individual rows.
+
+### Decode pipeline (the core)
+
+`decodeUri()` (triggered live on input) runs, in order:
+
+1. Validate the `MT:` prefix, then take the base38 payload after it.
+2. `base38Decode(str)` → `Uint8Array`. Charset is `0-9A-Z-.` (38 chars). Chunking is
+   **greedy**: 5 chars→3 bytes, 4→2, 2→1; a length that doesn't fit those groupings
+   throws `Invalid base38 string length`. Bytes are extracted **little-endian**
+   (`value & 0xFF`, then `>>= 8`).
+3. `extractBits(bytes, startBit, bitCount)` reads the 84-bit field layout **LSB-first**.
+   Fixed field order/widths (see the in-page "Data Encoding Format" table for the source of truth):
+   version(3), vendor ID(16), product ID(16), custom flow(2), discovery caps(8),
+   discriminator(12), passcode(27).
+4. Display helpers translate raw numbers: `getCustomFlowName`, `getDiscoveryCapabilities`
+   (bit flags: SoftAP / BLE / On IP Network), `formatVendorId`/`formatProductId`
+   (decimal + `0x`-hex padded to 4).
+
+### Vendor name lookup
+
+`getVendorName(id)` → `parseVendorMappings()` **lazily parses the embedded XML once**
+(cached on `vendorMap`, a `let` inside `setup()`) via `DOMParser`, keyed by
+`parseInt(code, 16)`. It is exposed reactively through the `vendorName` `computed`, so
+the lookup re-runs when the decoded vendor ID changes.
+
+## Gotchas
+
+- The `BarcodeDetector` scanner polls the camera via `setInterval` every 200ms and
+  auto-stops the first time it sees a QR starting with `MT:`; `stopScanning()` clears
+  the interval **and** stops the media tracks — keep those paired when changing scanning.
+- `parseVendorMappings` short-circuits on a non-empty `vendorMap`; if you add a mechanism
+  to update the map, clear/reset that cache or new codes won't be seen.
+- The relative links `/tools/` and `/` (header/footer) imply this page is deployed as part
+  of a larger static site (Tommie Gannert's blog/tools), but that site isn't in this repo.
+- `matter-decode.sh` is a bash port of the HTML app's decode pipeline, kept in lockstep
+  with it — the base38 charset/chunking, little-endian byte extraction, and the 84-bit
+  LSB-first field layout are identical. When you change the decode logic in the HTML app,
+  mirror it in the script (and vice versa). The script's only extra is a `manufacturers.tsv`
+  lookup for the vendor name; without that file it still decodes everything else.
+- `manufacturers.tsv` is regenerated with `gen-manufacturers.py` (Python 3
+  stdlib). Default source is the **upstream `manufacturers.xml` fetched over the
+  network** (via `curl`; a GitHub `blob/` URL is auto-rewritten to its
+   `raw.githubusercontent.com` form). A positional arg overrides with another URL
+  or a local XML file, and passing `matter-qr-decoder.html` uses the embedded
+   `<map>` block as an **offline** fallback. The default fetch is pinned to the
+  same commit the HTML block came from, so it reproduces the committed TSV
+  byte-for-byte. Caveat: the script writes **only the TSV** — the embedded
+   `<script type="text/xml">` block in the HTML app has the same upstream
+  provenance and a "do not edit manually" note, so refreshing the TSV from new
+  upstream XML leaves the HTML copy stale. Refresh both from the same source.

+# Matter QR Code Decoder
+
+Decode the commissioning QR code that Matter / CHIP devices ship with. A Matter
+device's setup QR encodes a short `MT:` URI that carries the information a
+commissioning app (e.g. Apple Home, Google Home, the Matter app) needs to pair
+with the device for the first time. This tool takes that URI and shows you what
+is inside.
+
+No build, no install, no package step. Two ways to use it: a browser app and a
+command-line script that share the same decode logic.
+
+## What it decodes
+
+Given an `MT:` URI, the payload (84 bits, see [Data format](#data-format)) is
+split into these fields:
+
+| Field | Meaning |
+|---|---|
+| **Version** | Encoding version (3 bits) |
+| **Vendor ID** | 16-bit manufacturer identifier, shown as decimal + `0x`-hex, with a name looked up from `manufacturers.tsv` when available |
+| **Product ID** | 16-bit vendor-assigned product identifier, decimal + `0x`-hex |
+| **Custom Flow** | Commissioning flow type: 0 = Standard, 1 = User Intent, 2 = Custom, 3 = Reserved |
+| **Discovery** | How the device can be found: **SoftAP** / **BLE** / **On IP Network** (a bitset — a device may show more than one) |
+| **Discriminator** | 12-bit discriminator |
+| **Passcode** | 27-bit commissioning passcode |
+
+## Components
+
+| File | What it is |
+|---|---|
+| [`matter-qr-decoder.html`](matter-qr-decoder.html) | The browser app. Single self-contained HTML file (Vue 3 + Bootstrap 5.3, loaded from CDNs). |
+| [`matter-decode.sh`](matter-decode.sh) | A pure-bash CLI port of the same decode logic. No camera scanning. |
+| [`manufacturers.tsv`](manufacturers.tsv) | Tab-separated `vendor ID → name` table (~900 rows) used to turn a numeric vendor ID into a name. Shared by both tools; optional. |
+| [`gen-manufacturers.py`](gen-manufacturers.py) | Python 3 script that regenerates `manufacturers.tsv`; pulls the upstream `manufacturers.xml` over the network by default (or a URL/local file/HTML block you pass in). |
+
+`CLAUDE.md` documents the internals for anyone (or Claude Code) working on the
+code.
+
+---
+
+## Browser app
+
+### Requirements
+
+- A modern browser with network access (the page loads Vue 3, Bootstrap 5.3, and
+  Bootstrap Icons from CDNs).
+- Camera scanning needs a **secure context** — serve it over `HTTPS` or
+  `localhost`, not `file://`:
+
+   ```sh
+  python3 -m http.server 8000
+   # then open http://localhost:8000/matter-qr-decoder.html
+   ```
+
+### Use it
+
+1. Paste an `MT:` URI into the **Input** box — decoding happens live as you type.
+2. Or click **Scan QR** and point your camera at the code. Scanning stops itself
+   the moment it reads an `MT:` QR.
+
+Two caveats:
+
+- **Scan QR is Chromium-only** (Chrome / Edge). It uses the `BarcodeDetector`
+  API. Firefox and Safari show a "not supported" message — **pasting a URI works
+  everywhere**, so use that on those browsers.
+- The **Data Encoding Format** and **Discovery Capabilities Bits** sections at the
+  bottom of the page explain the layout shown in the output.
+
+---
+
+## Command line
+
+`matter-decode.sh` decodes a URI from an argument or from stdin and prints the
+same fields as the web UI:
+
+```sh
+./matter-decode.sh "MT:..."
+echo "MT:..." | ./matter-decode.sh
+```
+
+Example output (run the URI through the script to reproduce):
+
+```
+$ echo "MT:O083635783973181337368400343813154179" | ./matter-decode.sh
+Version:      0
+Vendor ID:    13012 (0x32D4)
+Product ID:    50616 (0xC5B8)
+Custom Flow:  User Intent Commissioning Flow
+Discovery:    BLE
+Discriminator:1723
+Passcode:      8126392
+```
+
+(The vendor ID `0x32D4` isn't in `manufacturers.tsv`, so no name is printed —
+that's expected, not an error.)
+
+The script is pure bash (3.x+). It reads `manufacturers.tsv` from its own
+directory to resolve the vendor name; without that file every field still decodes
+and only the vendor name is omitted.
+
+---
+
+## Data format
+
+The URI is `MT:` followed by a **base38** payload (charset `0-9 A-Z - .`, 38
+symbols). The payload decodes to bytes, read **little-endian**, then sliced into
+the 84-bit field layout **LSB-first**:
+
+```
+version(3) | vendor ID(16) | product ID(16) | custom flow(2)
+           | discovery caps(8) | discriminator(12) | passcode(27)
+```
+
+Base38 decoding is greedy: 5 chars → 3 bytes, 4 → 2, 2 → 1; a length that fits
+none of those groupings is an error. Both the HTML app and the shell script use
+this same scheme, which is why the two stay in lockstep.
+
+## Vendor name lookup
+
+Both tools map a numeric **Vendor ID** to a name using
+`manufacturers.tsv` (`vendor ID` in the first column, name in the second). The
+table is derived from upstream
+`project-chip/connectedhomeip .../zcl/data-model/manufacturers.xml`
+(Apache-2.0, generated 2022-08-02). **Refresh it from upstream rather than
+hand-editing individual rows.**
+
+To refresh the table, run **`gen-manufacturers.py`** (Python 3 standard library
+only). By default it **pulls the upstream `manufacturers.xml` over the network**
+(via `curl`) and writes the sorted two-column TSV (`decimal id \t name`) to
+`manufacturers.tsv`:
+
+```sh
+python3 gen-manufacturers.py
+```
+
+The source is pinned to the same commit the HTML block was generated from, so a
+fresh pull reproduces the current `manufacturers.tsv` exactly. To refresh from a
+different upstream revision, pass a source — a URL (a GitHub `blob/` URL is
+auto-rewritten to its `raw.githubusercontent.com` form) or a local XML file:
+
+```sh
+python3 gen-manufacturers.py https://.../manufacturers.xml
+python3 gen-manufacturers.py ./manufacturers.xml
+```
+
+No network? Use the embedded block as the source instead:
+
+```sh
+python3 gen-manufacturers.py matter-qr-decoder.html
+```
+
+The same table is also embedded as a `<map>` XML block near the end of
+`matter-qr-decoder.html` (marked "do not edit manually"). This script regenerates
+only the TSV, so if you refresh the TSV from new upstream XML, also paste that XML
+into the HTML's `<script type="text/xml">` block to keep the two copies in sync.
+
+## License
+
+The vendor mapping is derived from Matter/CHIP's `manufacturers.xml`, which is
+Apache-2.0. The app itself is a small single-file utility.

+# matter-decode.sh — decode a Matter commissioning QR code (MT: URI) from the CLI.
+#
+# This is a bash port of the decode logic in matter-qr-decoder.html (the browser
+# app's camera/QR-scanning feature has no shell equivalent and is intentionally
+# omitted). It decodes the 84-bit payload and prints the same fields the web UI shows.
+#
+# Usage:
+#   ./matter-decode.sh "MT:..."
+#   echo "MT:..." | ./matter-decode.sh
+#
+# A companion file manufacturers.tsv (same directory) maps vendor IDs to names.
+# It is derived from project-chip/connectedhomeip's manufacturers.xml and is
+# optional: without it, all fields still decode — the vendor name line is simply
+# skipped. Regenerate it with:  python3 gen-manufacturers.py  (see that file).
