The 9-Stream Enginethe ACI duality pipeline, running · OG → FSS → BSS → OG′

The Duality Engine as a live runtime. A deterministic HACI lexer and parser turn your source into operations, and those operations flow the rail: OG (the committed state) → FSS (every proposal, optimistically) → BSS (only the backed ones survive) → OG′ (the new commit). Five audit streams watch both halves and three feedback loops close it. No RNG — every hash is computed; the same input always gives the same picture. Watch an unbacked operation get dropped at the BSS gate — and press 🔊 sapphic voice to hear it: each op becomes a lyre note in Sappho's Mixolydian mode, the LIMEN gate-cadence resolving a commit up to the octave and letting a rejection fall, all in the Sapphic metre.

the 9 streams + 3 loops
what this is. a deterministic visualization of the ACI duality pipeline, built from the ground up on the HACI / MACI grammar and the Duality Engine's FS/FSS/BSS discipline. The four pipeline streams (OG · FSS · BSS · OG′) are computed live from your input; the five audit streams carry the engine's verified standing (HACI torture 1108/1108, MACI 3929/3929, brutal 40/44). Loops: A the commit loop (drifts on a reference error or a cycle), B the HACI QA loop, C the MACI QA loop.
the voice. a fusion of three domains: the scale is the genuine ancient Mixolydian (Sappho's mode) in Pythagorean tuning on a Karplus-Strong lyre (from Sounds of Lesbos); the cadence is LIMEN's gate law — a crossing voiced as a pitch, a commit resolving up, a rejection falling (from the Sapphic Carrier); the rhythm is the real quantitative Sapphic metre. Each op's note is a Mixolydian degree picked deterministically from its path — so the same source always sings the same song.
honest line. this is a runtime view — the parser is a compact deterministic lexer/parser for the HACI shape, not the full reference validator; the torture/brutal numbers are the engine's verified results, shown as standing audit streams, not re-run in the browser. No randomness in the pipeline: the hashes, the flow, and the melody are a pure function of the source (only the lyre's pluck excitation is noise, as physical strings are).
