It +describes the **current** format — a SQLite database — and the **legacy** format +(a ZIP archive) that current readers still accept and migrate. + +> An earlier revision of this document described the ZIP container as the current +> format. That is now historical; see [§11 Legacy ZIP format](#11-legacy-zip-format-pre-sqlite). + +## 1. Notational conventions + +The key words **MUST**, **MUST NOT**, **SHOULD**, **SHOULD NOT**, and **MAY** are +to be interpreted as described in RFC 2119. + +Byte sizes use binary units: `KiB = 1024`, `MiB = 1024²`, `GiB = 1024³`. + +"UUID" means an RFC 4122 128-bit identifier. Unless stated otherwise, a UUID is +serialized in JSON as its canonical hyphenated lowercase string, and stored in +SQLite as its 16 raw bytes in **network (big-endian) byte order** — i.e. the byte +sequence returned by `Uuid::as_bytes`, most significant byte first. + +## 2. Overview + +A `.beam` file is a **single SQLite 3 database** (default rollback journal; no WAL, +no special pragmas) containing: + +- one JSON document, `project.json`, holding all project state that is small and + structural (the document/scene tree, audio project, asset metadata); and +- zero or more **media** items (audio, raster frames, image assets, and derived + blobs such as waveforms and thumbnails), each either **packed** into the database + in chunks or **referenced** by an external file path. + +The design goals are: a single beginner-friendly file (no project folder); +streaming reads of large media via SQLite blob I/O; transactional, crash-safe, +**in-place** saves that do not rewrite unchanged media; and inspectability with the +ordinary `sqlite3` CLI. + +## 3. File identification + +A reader MUST determine the container type from the first 16 bytes of the file: + +- If the first 16 bytes equal the ASCII string `SQLite format 3\0` (i.e. + `53 51 4C 69 74 65 20 66 6F 72 6D 61 74 20 33 00`), the file is a SQLite + `.beam` and MUST be read per [§4](#4-container-the-sqlite-schema)–[§10](#10-load-semantics). +- Otherwise the file is treated as a [legacy ZIP `.beam`](#11-legacy-zip-format-pre-sqlite) + (ZIP local-file-header magic `50 4B 03 04`). + +The `.beam` extension is used for both container types; the magic bytes — not the +extension — are authoritative. + +## 4. Container: the SQLite schema + +A conforming SQLite `.beam` MUST contain exactly these four tables (DDL as created; +column order and types are normative): + +```sql +CREATE TABLE media ( + id BLOB PRIMARY KEY, -- 16-byte UUID (big-endian) + kind INTEGER NOT NULL, -- MediaKind (§6.1) + codec TEXT NOT NULL, -- original codec/container, e.g. "flac","mp3","png" + storage INTEGER NOT NULL, -- MediaStorage (§6.2): 0=Packed, 1=Referenced + ext_path TEXT, -- external path, set iff storage=Referenced + total_len INTEGER NOT NULL DEFAULT 0, -- payload length in bytes (packed); 0 if referenced + channels INTEGER, -- audio: channel count (nullable) + sample_rate INTEGER, -- audio: sample rate in Hz (nullable) + width INTEGER, -- visual media: pixel width (nullable) + height INTEGER -- visual media: pixel height (nullable) +); + +CREATE TABLE media_chunk ( + id INTEGER PRIMARY KEY, -- rowid (used as the handle for blob streaming) + media_id BLOB NOT NULL, -- → media.id + chunk_index INTEGER NOT NULL, -- 0-based ordinal of this chunk + bytes BLOB NOT NULL, -- chunk payload + UNIQUE (media_id, chunk_index) +); + +CREATE TABLE project_json ( + id INTEGER PRIMARY KEY CHECK (id = 0), -- exactly one row, id 0 + data TEXT NOT NULL -- the serialized BeamProject (§8) +); + +CREATE TABLE meta ( + key TEXT PRIMARY KEY, + value TEXT NOT NULL +); +``` + +There is no foreign-key constraint between `media_chunk.media_id` and `media.id`; +referential integrity is maintained by the writer. A reader MUST NOT assume SQLite +enforces it. + +### 4.1 The `meta` table + +Defined keys (all values are strings): + +| Key | Value | Meaning | +|------------------|--------------------|---------| +| `schema_version` | `"1"` | Container schema version. Set once at creation. | +| `version` | `"1.0.0"` | Project payload version (mirrors `project.json`'s `version`). | +| `created` | RFC 3339 timestamp | Creation time. Preserved across in-place re-saves. | +| `modified` | RFC 3339 timestamp | Last save time. Updated on every save. | + +Writers MAY add additional keys; readers MUST ignore unknown keys. + +### 4.2 Two independent version numbers + +The format carries **two** version numbers with different compatibility rules: + +- **`meta.schema_version`** (`INTEGER`, currently `1`) — versions the SQLite + container/table layout. A reader MUST reject a file whose `schema_version` is + **greater** than the highest it supports, and SHOULD accept any value less than + or equal to its maximum (forward-compatible for older files). +- **`BeamProject.version`** / `meta.version` (currently `"1.0.0"`) — versions the + `project.json` payload. The current implementation requires **exact string + equality** and rejects any other value. A future revision MAY relax this to a + semantic-version range; until then, writers MUST emit exactly `"1.0.0"` and + readers reject anything else. + +These two numbers are orthogonal and MUST both be checked. + +## 5. UUIDs and identity + +Every media item is identified by a UUID. In `project.json` UUIDs appear as +canonical strings; in the `media`/`media_chunk` tables they appear as 16 raw +big-endian bytes (`media.id`, `media_chunk.media_id`). A reader MUST treat the two +representations as equal by their 128-bit value. + +`media_chunk.id` is the SQLite rowid and is the handle a reader uses to open a blob +for streaming (`sqlite3_blob_open` on table `media_chunk`, column `bytes`). It has +no meaning beyond row identity and MUST NOT be relied upon to be stable across +re-saves. + +## 6. Media model + +### 6.1 `MediaKind` (`media.kind`) + +| Value | Kind | `codec` examples | Notes | +|-------|---------------|------------------|-------| +| `0` | `Audio` | `flac`, `mp3`, `wav`, `ogg`, `opus`, `aac`, `m4a`, `alac`, `caf`, `aiff` | Source audio for a pool entry. | +| `1` | `Video` | `mp4`, `mov`, … | A video clip's container bytes, keyed by the clip id. Packed under the large-media policy (referenced above 2 GiB unless `Pack`). Frames **and** the embedded audio stream are decoded directly from this blob. | +| `2` | `Raster` | `png` | Full-resolution pixels of a raster keyframe (PNG-encoded RGBA). | +| `3` | `ImageAsset` | `png`, `jpg`, … | An imported image asset's original bytes. | +| `4` | `Waveform` | `lbwf` | Precomputed waveform LOD pyramid for an audio item. Opaque blob owned by `daw_backend::audio::waveform_pyramid`. | +| `5` | `Thumbnail` | `lbtn` | A pack of precomputed video thumbnails for a clip. Opaque blob owned by the editor. | +| `6` | `RasterProxy` | `png` | Low-resolution PNG proxy of a raster keyframe, shown during cold scrubs while full-res pages in. | + +A reader MUST reject a `kind` value it does not recognise only if it needs that +item; unknown kinds MAY otherwise be ignored. + +### 6.2 `MediaStorage` (`media.storage`) + +| Value | Storage | Bytes location | `total_len` | `ext_path` | +|-------|--------------|----------------|-------------|------------| +| `0` | `Packed` | `media_chunk` rows in this DB | payload length | `NULL` | +| `1` | `Referenced` | external file at `ext_path` | `0` | path string | + +### 6.3 Packed storage and chunking + +Packed bytes are split into chunks of **`CHUNK_SIZE = 4 MiB`** and stored one chunk +per `media_chunk` row, ordered by `chunk_index` ascending starting at `0`. The +writer MUST: + +1. set `media.total_len` to the exact total byte length of the payload; +2. write `ceil(total_len / CHUNK_SIZE)` chunk rows (zero rows iff `total_len == 0`); +3. make every chunk exactly `CHUNK_SIZE` bytes **except the last**, which holds the + remainder `total_len − (n−1)·CHUNK_SIZE`. + +Because chunk lengths are fully determined by `total_len` and `CHUNK_SIZE`, a reader +performing random access MUST compute, for a byte offset `pos < total_len`: + +``` +chunk_index = pos / CHUNK_SIZE +offset_in_chunk = pos % CHUNK_SIZE +chunk_len = min(CHUNK_SIZE, total_len − chunk_index·CHUNK_SIZE) +``` + +and read from the row with that `chunk_index`. A reader MAY stream the whole payload +by concatenating chunk `bytes` in `chunk_index` order. The chunk size MAY differ in +files written by other tools; a robust reader SHOULD derive chunk boundaries from +actual row lengths rather than assuming 4 MiB. (The reference reader assumes uniform +`CHUNK_SIZE` except for the last chunk; writers targeting it MUST keep chunks +uniform.) + +### 6.4 Referenced storage + +A referenced item stores only `ext_path` (with `total_len = 0` and no chunk rows). +The path is resolved relative to the directory containing the `.beam` file unless it +is absolute. If the file is absent at load time, the item is reported as a *missing +file* ([§10.4](#104-missing-referenced-files)) — this is non-fatal. + +## 7.

Unchanged packed media MUST NOT be rewritten (§9.3); this is + the central performance/crash-safety property, and writers MUST NOT use a + copy-to-temp-and-rename flow for in-place saves. +- Otherwise (new file, or migrating a legacy ZIP), the writer creates a fresh DB at + `.beam.tmp`, writes everything, commits, then atomically `rename`s it over + the target. + +### 9.2 Order of operations within the transaction + +1. Audio pool entries → `Audio` (+ `Waveform`) media rows. +2. Raster keyframes → `Raster` (+ `RasterProxy`) media rows. +3. Video thumbnail packs → `Thumbnail` media rows. +4. Video clips → `Video` media rows (packed/referenced per the large-media policy); + when a clip is packed, its linked video-audio pool entry's `media_id` is set to + the clip's `Video` row so the audio streams from the same blob. +5. Image assets → `ImageAsset` media rows. +6. **Garbage-collect**: delete every `media` row (and its chunks) whose id is **not** + in the set of live ids accumulated in steps 1–5. +7. Write `project.json` and the `meta` keys (`version`, `created`, `modified`). +8. Commit; then (create path only) rename the temp file over the target. + +### 9.3 Packed vs. referenced decision (audio) + +For each audio pool entry, in order: + +- If a packed row for its `media_id` already exists in the archive, keep it untouched + (do not rewrite the bytes) and keep the entry packed. +- Else if its external file resolves and exists: store **referenced** if the entry is + video audio, *or* the file is `≥ LARGE_MEDIA_THRESHOLD` (2 GiB) and the large-media + mode is not `Pack`; otherwise **pack** it (streamed from disk chunk-by-chunk). +- Else if it has `embedded_data`: base64-decode and pack it. +- Else: leave its references as-is (it will be reported missing on load). + +Raster, image, and thumbnail media follow the same "write if present, else keep the +existing row" rule so that paged-out content survives a save without being held in +memory. + +## 10. Load semantics + +### 10.1 Dispatch and version checks + +Open the file, read `project.json`, parse `BeamProject`. Reject unless +`version == "1.0.0"` (§4.2). The container's `schema_version` is verified on open +(`≤` the reader's maximum). + +### 10.2 Audio resolution + +Per pool entry with a `media_id`: look up the media row. If its `codec` is a +**streamable** audio codec (`mp3`, `flac`, `ogg`/`oga`, `wav`/`wave`, `aiff`/`aif`, +`aac`, `m4a`, `opus`, `alac`, `caf`), the bytes are **streamed lazily** from the blob +at playback time (the entry keeps `media_id`, with `embedded_data`/`path` cleared). +Otherwise the bytes are read eagerly into `embedded_data`. A precomputed `Waveform` +blob, if present, is read into the entry. + +### 10.3 Visual media paging + +- **Raster** full-res pixels are **not** eagerly decoded; each keyframe is flagged + for fault-in and its pixels are paged from its `Raster` row on demand. Its + `RasterProxy` PNG **is** read and decoded eagerly so cold scrubs show a low-res + frame immediately. +- **Image assets** are **not** eagerly read; they page from their `ImageAsset` rows + on demand. +- **Thumbnail** packs are read eagerly per video clip. + +### 10.4 Missing referenced files + +A pool entry that is neither packed nor embedded, whose `relative_path` resolves to a +non-existent file, MUST be reported as a missing file (non-fatal). The host +application prompts the user to relocate it. + +## 11. Legacy ZIP format (pre-SQLite) + +Files whose magic is not `SQLite format 3\0` are read as a ZIP archive with this +internal layout: + +- `project.json` — the same serialized `BeamProject` (`version` must be `"1.0.0"`). +- `media/audio/.` — audio source files. The codec is taken from the + extension. **FLAC entries are decoded to PCM `f32` and re-encoded in memory as + IEEE-float WAV (WAV format tag 3)** before being base64-embedded; other formats are + embedded as-is. The entry's `relative_path` is cleared after extraction. +- `media/raster/.png` — raster keyframe pixels, named `media/raster/.png` + after the keyframe's `id`. + +A reader MUST NOT modify a legacy ZIP on open; it loads into memory only. **The next +save migrates the project to SQLite** (the save sees a non-SQLite target, so it takes +the create-and-rename path and writes a fresh `.beam` database). + +> Known limitation of the legacy reader: raster pixels are loaded only for +> **top-level** layers; raster keyframes nested inside groups/clips are not populated +> from a ZIP. The SQLite path recurses correctly. Re-saving to SQLite is the remedy. + +## 12. Large-media policy + +- `LARGE_MEDIA_THRESHOLD = 2 GiB`.
