01 / UNDERSTAND / SDN
One identity.
Several independent axes.
SDN is Seudo Direccional Nominador: the internal machine-first information domain.
The width envelopes
| WIDTH | FIELDS | VIEW | READER IN | DOCTOR |
|---|---|---|---|---|
| 04Char | CORE4 | Point / nucleus | 12Char | 12Char |
| 06Char | CORE4 + PLACE2 | Line | 04Char | 04Char |
| 08Char | LOC2 + CORE4 + PLACE2 | Grid | 06Char | 06Char |
| 12Char | LOC2 + CORE4 + PLACE2 + DIR4 | Oriented lattice | 08Char | 08Char |
CORE4 persists. The 3^0 through 3^3 labels name doctrinal orders. They are not arithmetic equalities with the character counts.
Width is not stage
Width, temporal role, codec, physical carrier and object identity are separate fields. Widening a token is not automatically compression or a move into the future.
NOW and the stage field
| STAGE | ROLE | MEANING |
|---|---|---|
| .sd4 | WITNESS / ADMISSION | Raw witness and admitted source evidence |
| .sd3 | TRANSPORT / COMPACTION | Verified transportable representation |
| .sd2 | WORKBENCH / REVEAL / SURGICAL | Expanded inspection and default human surgical editing surface |
| .sd1 | ABSTRACTION / ORGANISATION | Dictionary, references, grammar and Brother Quicky organisation |
| .sd0 | VAULT / SEALED CURRENT VERIFIED LOCAL MINIMUM | Current verified sealed representation selected from tested candidates |
| .sdn | NOW / LIVE | Active live object / temporary mind node |
| .sd5 | PROXIMATE | Near projection |
| .sd6 | PREDICTIVE | Predictive projection |
| .sd7 | SCENARIO | Alternative scenario projection |
| .sd8 | FRONTIER | Farther practical projection frontier |
| .sd9 | HORIZON | Practical projection horizon |
Projection horizons have no fixed time spacing frozen here. Projected state must be compared with later observations before becoming admitted realised evidence.
The carousel
STAGE^n → CANDIDATE → VERIFY → END^n → RE-ADMIT
A newly useful reversible view can enter the next candidate arena. Count the whole object: payload, metadata, dictionaries, inverse/reconstruction information and proof.
.sd0 is the smallest verified complete object in a named tested local arena. .sd2 may grow to become inspectable. A bijection alone does not compress every input.
TRY THE CANDIDATE ARENA →SDO / a nominated envelope
The implemented profile expands SDO as Sealed Data Object. The broader architecture uses persistent nominated object/message envelopes with state, lineage and proof. The browser lab names its exact E8I-SDO-6 reference profile.
DNA/RNA is functional grammar. Meaning and semantic interpretation are another organ.
