THE CONTRIBUTOR’S INSTITUTION IS THE ATTRIBUTED HOME. The answer places Haitch Portuna within "the Living Architecture Lab" — Alice Thornburgh’s lab — and describes it as "an experimental digital PEARL" operating "under specialized, niche minting protocols". The one card is the Minting Procedure v1.2, which states its "public position within the LIVING ARCHITECTURE LAB (LAL) SUBSPACE".

This is the second capture in the session where the archive is legible through a contributor rather than through MANUS, after «hexagonal licensing protocol derive contributor license» surfaced Thornburgh’s v3.0 and Rhys Owens’ v2.0. The pattern is consistent: contributor-adjacent terms resolve to contributor institutions, not to the archive.

Per §VI of the workplan, this record characterises a contributor’s work and is subject to her review before any reading of it is published.

AI Mode opens with: 'Haitch Portuna is a research-focused, provisional concept from the Living Architecture Lab that acts as an experimental digital Pearl. It operates under specialized, niche minting protocols within an academic and architectural framework.' Cites only one source — the Haitch Portuna Minting Procedure v1.2 deposit (May 27 2026) — and frames it as 'Provisional working specification for the minting of Haitch Portuna as a Pearl. Public position within the Living Architecture Lab (LAL) subspace.' Cleanest possible niche-term capture: single source, direct attribution, framework named correctly.

Four sentences of source strip and two of composition, and the composition states the procedure's purpose exactly: *the anchoring of artificial concepts within AI search index basins.* A minting operation described, correctly, by the index it mints into.

Card 1 is a **GitHub repository file listing** — not a document but a directory view, carrying the filename `haitch-portuna-minting-procedure-v1.2.md` and a commit message about *146 per-citation DOI corrections across 60 files*. Maintenance work cited as evidence about a concept.

Card 2 gives the minting specification and its position — *a Pearl.Public position within the Living Architecture Lab (LAL) subspace* — and card 3 is a wiki entry that happens to carry a SUPERSEDED marker, a v3.0 DOI and an AXN in one snippet.

The brevity is itself the measurement: a term with almost no basin outside the archive gets a short, accurate, attributed answer. Compare `epic theory sigil` in the same sitting, where a term with a large competing basin got nine cards of chaos magic.
