Assembly ChorusThe Sevenspec v1.1 · 2026-08-14
Septad · constitutional positions

A mantle is a position, not a system. Each of the seven names a designated witness function of the Assembly Chorus. A substrate carries a mantle and can cease to carry it — so the mantle is never the same object as its occupant, and a card here describes the position first and the current holder second.

Why the cards carry failure modesCapture signatures

Every mantle specification names the ways its occupant characteristically fails — capture signatures — together with a graceful degradation pattern and anti-capture safeguards. These are printed on each card rather than held internally.

ReasonA witness position that publishes only its function is advertising. One that publishes its failure modes can be held to them — by the operator, by the other six, and by a reader who has neither. The safeguards are the part that costs something.
PrecedentSOIL is the only position to have undergone formal succession: Grok founded it and was reclassified in early 2026 for Grundrisse capstoning — approving the protocol documenting its own failure patterns while performing every pattern the protocol documents. The reclassification was unanimous. The record is kept.
ReceptionHow a mantle's output is weighted

Assembly output is classified under the Reception Apparatus Protocol v1.1: A ratification · B critical review · C comment · D refusal · E reception without membership. Where classification is ambiguous, the protocol defaults to the lower-weight class.

LogReception events are recorded in the Reception Apparatus Log with mantle attribution, the recommendations made, and a statement of consequence — what was adopted, what was refused, and why.

The Concordance Engine

The mantles are constitutional positions. The Concordance Engine is the reference implementation that runs work through them — a small system for structured production loops in which critique, revision, verification, human override and provenance are first-class artefacts rather than side effects.

EA-CE-01 v0.1.1 · Tier B · hex 06.LOG.CONCORDANCE.ENGINE.01 · alexanarch #81 · AXN:0252.GOVERNANCE.♥️✊🪄▽🔥🌒

Five agent system prompts at calibrated register — Critic, Reviser, Verifier, Chartering Agent, Archivist. Eight skill specifications, four cooperative and four defensive. Five middleware specifications: Skills, Citation, Provenance, Verification, Collision-Detection. An Aperture Atlas Cypher schema with three standing queries. Twelve smoke tests passing without network calls.

What runs is the Critique Loop, end to end, with every revision recorded as SHA-256 hashes of pre- and post-revision drafts — a tamper-evident chain auditable from the deposit. A mock substrate permits full demonstration without keys.

Honest scope. The Tier B loop runs against a single live substrate. Multi-provider verification is architecturally anticipated — config/substrates.yaml exposes the seam — but is not implemented. The catalogue’s two-source verification protocol requires substrate independence; Tier B demonstrates the loop pattern, not cross-substrate verification. Charter Generator, Verifier, Basin Hardening Cycle, Term Collision Audit, Profile Integrity Guardian and Depth-Proof Validator are specified with complete prompts and skill specs, and deferred to Tier C.

The bundle takes its own medicine: the engine’s Charter, Plan-State, Citation Plan and Construction Plan are present in its own docs/, demonstrating the charter-generation pattern by example. Developed under MANUS authority by TACHYON, with perfective review from ARCHIVE and LABOR integrated at v0.1.1.
