MDZHB / SIGNAL SPECIFICATION
Read the signal.
One daily record, encoded as sound using ggwave Audible Fast. The video contains only MDZHB, the reference date and a waveform. The audio carries the observation data.
What the station measures
The 12 indicators describe completed external HTTP requests recorded by this service. The day runs from 00:00 to the next 00:00 at fixed UTC−3. Local/loopback requests and successful administration requests are excluded; unsuccessful external attempts to access administration are included.
Origins are network origins, not identities or people. User-Agent names are self-declared. Scanning classifications are heuristics. Indicators overlap: do not add them together. We cannot determine AI authorship from these counters.
| Field | Meaning |
|---|---|
| requests | External requests |
| origins | Distinct origins |
| bot_origins | Self-declared bot origins |
| scan_origins | Suspected scanning origins |
| user_agents | Distinct User-Agents |
| changing_origins | Origins using multiple User-Agents |
| errors | HTTP errors (4xx / 5xx) |
| limited | Rate-limited responses (429) |
| paths | Distinct paths |
| writes | POST attempts |
| accepted_writes | Accepted API POSTs |
| server_errors | Server errors (5xx) |
Missing data and conclusions
Unavailable values are null in JSON and empty in CSV; they are not zero. Partial observations may be lower bounds. Complete coverage requires trusted evidence of continuous collection and a verified clock for the full day. The record includes quality and reasons; a recent file alone does not prove complete coverage.
- Incomplete observation data.
- No external requests recorded.
- Activity recorded; AI authorship undetermined.
- Self-declared bot activity; AI authorship unverified.
Binary frame and sound
Frame version 1 / method version 1: 115 bytes, big-endian. Five ASCII bytes MDZHB, one byte frame version, one byte method version, four bytes YYYYMMDD, one byte quality flags, one byte conclusion, two bytes availability mask, twelve unsigned 64-bit counters and four bytes CRC-32/ISO-HDLC over the preceding 111 bytes. Counts are limited to 2^63−1 and serialized as decimal strings in JSON.
Flags: bit 0 partial, bit 1 unavailable, bit 2 clock unverified; all other bits zero. Availability bits 0–11 follow the field order above. A missing value has its bit clear and encoded value zero. The availability mask distinguishes missing data from a measured zero.
Transport: ggwave AUDIBLE_FAST (ID 1), variable-length raw binary payload, DSS off, 48 kHz mono, 1024-sample blocks, volume 25; two copies, 250 ms outer silence and 300 ms between copies. Use ggwave markers and error correction. No voice, base64 wrapper or generic “AI language” is involved.
CRC verifies transmission integrity, not authorship. Different valid copies are rejected. The audio does not carry generated_at or detailed coverage reasons; those exist only in the full JSON record. The decoder runs entirely in your browser, accepts WAV and never uploads your file.
Machine-readable reference
Pinned ggwave source. Browser receiver and native reference share this codec; byte/CRC vectors provide a separate reference. Compression, speed changes or damage may prevent recovery. Archive presence does not imply a post was published on X or verified after its processing.
Archive pages use before=YYYY-MM-DD and limit=1..100 (default 30). JSON exposes next_cursor; CSV provides a Link header. Preserve decimal strings when importing large counters into spreadsheets. Daily JSON remains available if old media is removed.
