Librarian and Data Trust
Nishi vs the field — every Nishi cell is measured against real organ source at emit time; each gap names the watch contract that will close it.
Nishi vs DataHub and OpenMetadata and Collibra and Atlan
Layer 1 · Executive
Where we are. The librarian and data-trust plane is structurally ahead of the catalogs: content-addressed identity (exceed), tamper-evident append-only store (exceed), silicon-up genesis lineage (exceed), C2PA-class signed provenance with deny-by-default verification (two exceeds), the no-new-TSV live guard (exceed), the format-sprawl audit (exceed), universal library foundationing of 1,314 of 1,314 docs (exceed), plus dataset lineage, dedup, freshness state machine, schema drift, compaction, BM25 over the library, the librarian review with RACI handoff and a live cross-team orchestration engine (exceed). Behind the catalogs on: applied subject classification, a RUNNING freshness beat, the MCP orchestration API, column-level lineage, contract enforcement at ingest, and a catalog UI.
Where we need to go. A library that is CLASSIFIED and BROWSABLE, kept fresh by a beat rather than a session, enforced at the door by data contracts, traced to the column, and engaged by any team through one MCP door -- on the same signed content-addressed substrate that already exceeds the field.
The unit. 1 u = one measured session-leg (estate calibration: graphics R21 in one leg 2026-08-15). Local evidence: library foundationing (1314/1314, resumable) and the orchestration engine (13/13, proven live) each landed in one leg; estimates are relative to those.
Where we are: 6 open rungs. Trust substrate exceeding; curation, cadence and surfaces behind. Counts measured at emit below this line.
Cost to a living library: 1 u. LI1 the freshness beat -- the organs exist, nothing runs them on a cadence.
Cost to a browsable catalogue: 3.5 u. LI2 applied subject classification of the whole corpus, LI3 the catalog UI over it.
Cost to trust depth and autonomy: 6 u. LI4 contract enforcement at ingest, LI5 column-level lineage, LI6 the MCP orchestration door.

| Licence text acquired for the unread rows (LX1) after LX0 | aq_license_fetch | For every acquire_sources.conf row at evidence=NONE, fetch the upstream LICENSE into our own mirror, pin its digest and lift the row to READ so its bytes become mirrorable; gate proves a row cannot reach READ without a mirrored licence file whose digest is pinned, and that a fetch failure leaves the row at NONE rather than advancing it | Organ | 1.5 u |
| Upstream rot watch over acquired works (LX2) after LX1 | aq_rot_scan | Re-probe every acquired upstream URL on a beat and record DISAPPEARED versus CHANGED versus INTACT against the pinned digest we hold, so the library can prove it still holds a work its source no longer serves; gate proves a source that stops resolving is reported DISAPPEARED while our held bytes still verify | Organ | 1.5 u |

Layer 3 · Engineering
How this is scored. Every Nishi mark is measured: the generator reads the real organ source on disk and requires the implementing symbol to exist (no self-grading). A watching tag names the organ and symbol contracted to close a gap — the mark flips itself on the next compare beat when that workstream ships, and the
comparewatch- plane row flips with it. The flip is necessary, not sufficient: it proves the symbol exists, never that the capability is good. The bar is the rung's pre-declared done-rule, proven by its gate — a symbol shipped without the behaviour behind it is a defect, and the flip is exactly what makes that defect visible instead of quiet. Competitor marks record documented capability presence — presence, not depth or scale. Adoption is measured too: every measured row carries where its organ stands on the estate's ladder (source → built → promoted → registered → invoked; libraries by importer reach minus validation importers; gates by the execution surfaces that run them). A row is fully adopted only at the top of its ladder; anything short is tagged partial with the exact remedy, so a build nobody promoted can no longer read as shipped. Census stamps: importers asof 1787849099, gate census asof 1787855507 (unix seconds; -1 = census absent).Capability matrix — measured against source

Licence-EVIDENCE class gating rights at ingest (declared vs read)Measured exceed:aq_decide in runtime/nx_acquire_lib.nx, verified at emit. An UNREAD licence ABSTAINS and can never grant. Measured on the NAVER LABS Europe listing 2026-08-25: 2 of 26 releases carry any licence string (77 permil), both prose not a field, so a catalog that stores a licence STRING is storing an upstream assertion as if it were a fact. Gate 25/25 (now 40/40 with fixity), three bite-proven neg-controls, one compiling mutant killed. DRIVEN LIVE by runtime/nx_acquire.nx over the real NAVER LABS registry: rows=26 clear=1 review=25 refuse=0 malformed=0 sum=26 partition=RECONCILES, with naverlabs_anny carried the whole way -- listing page mirrored, licence URL derived, licence FETCHED and READ (Apache-2.0 confirmed by reading, not by the listing's assertion), pinned and SWHID'd -- and every other row honestly at REVIEW Adoption: LIB-WIRED importers=2 nonval=1 — fully adopted (top of its ladder). | ◉ | ○ | ○ | ○ | ○ |
Four independent verdicts per external work (mirror, redistribute, learn, attribute)Measured exceed:aq_res in runtime/nx_acquire_lib.nx, verified at emit. They fail apart in practice: collapsing them is how a work gets mirrored for study then accidentally republished. Attribution is modelled as an OBLIGATION that takes the MAX and never abstains, so I-could-not-look can never lighten a duty; catalogs model licence as a tag, not as a duty with a direction Adoption: LIB-WIRED importers=2 nonval=1 — fully adopted (top of its ladder). | ◉ | ○ | ○ | ○ | ○ |
Rights refused unless the licence row is CONFIRMEDMeasured exceed:lg_eval in runtime/nx_licgate_lib.nx, verified at emit. verified was parsed into the table, printed by list, and never consulted by the verdict until 2026-08-25 -- sdxl-base-1.0 returned SHIP_OK exit=0 from a row the table itself marks UNCONFIRMED. Unverified rows now cap at CONDITIONAL, a strict tightening measured to move exactly one model and only toward REVIEW Adoption: LIB-WIRED importers=2 nonval=2 — fully adopted (top of its ladder). | ◉ | ○ | ○ | ○ | ○ |
Licence text acquired into our own mirror for the unread rowsOpen — watchingruntime/nx_acquire_license.nx : aq_license_fetch, re-measured on every compare beat. Ship that symbol and this mark flips itself; the comparewatch- plane row flips with it. 24 of 26 acquire_sources.conf rows sit at evidence=NONE and their bytes are therefore unmirrorable by our own door; the remedy is to fetch each upstream LICENSE into the mirror and pin its digest, which is the only thing that can lift a row to READ | ○ | ○ | ○ | ○ | ○ |
Byte-length fixity beside every digest (the truncation a pin cannot see)Measured exceed:aq_fixity in runtime/nx_acquire_lib.nx, verified at emit. A digest answers are-these-the-bytes-I-hashed. Only a LENGTH answers are-these-ALL-the-bytes. A body truncated in transit whose digest was then computed on what ARRIVED verifies CLEAN, and researched Aug-2026 neither in-toto DigestSet nor SPDX verifiedUsing carries a byte length anywhere, so both are structurally blind to it. Our provenance row already carried bytes beside sha256 and nothing read it. Gate 40/40 with the truncation case BITE-PROVEN, and three states so an unrecorded length can never read as MATCH Adoption: LIB-WIRED importers=2 nonval=1 — fully adopted (top of its ladder). | ◉ | ○ | ○ | ○ | ○ |
Digest shape DERIVED from its algorithm rather than assertedMeasured exceed:aq_digest_shape_ok in runtime/nx_acquire_lib.nx, verified at emit. The expected hex length comes from the algorithm that produced the digest, never a hand-picked constant. Measured in the field: the Croissant specification's own canonical FileObject examples put six values in a property named sha256, of which four are 32 hex characters (an MD5 length) and one is 40, so a validator that recomputes SHA-256 fails the specification's own examples. A field named for one hash routinely carries another, so the NAME is a claim and the LENGTH is the check Adoption: LIB-WIRED importers=2 nonval=1 — fully adopted (top of its ladder). | ◉ | ○ | ○ | ○ | ○ |
Forge-independent ISO-standard identity (SWHID)Measured exceed:swhid_cnt in runtime/nx_swhid_lib.nx, verified at emit. ISO/IEC 18670:2025, spec V1.2. Computed from the file BYTES alone -- no filename, no path, no mtime -- so ANYONE can recompute it and confirm our copy is the same object Software Heritage holds, with no registry and no hosting forge in the loop. That is the anti-rot property: the pointer can die and the identity survives. SPDX 2.3 Annex F accepts swh as a Persistent-Id and DataCite 4.7 added it as a relatedIdentifierType, so one identifier reads in two ecosystems. Gate 18/18 against NINE differential vectors produced by git 2.49.0, an INDEPENDENT implementation rather than values we asserted; blob framing bite-proven; one compiling mutant killed. Carried BESIDE our sha256 and byte length and never instead of them: SHA-1 has chosen-prefix collisions since SHAttered 2017, so a SWHID is an interoperable NAME and never tamper evidence Adoption: LIB-WIRED importers=3 nonval=2 — fully adopted (top of its ladder). | ◉ | ○ | ○ | ○ | ○ |
Risk register
| Risk | Likelihood x impact | Mitigation |
|---|---|---|
| A classifier that shelves by title fills the catalogue with confident wrong shelves | possible x medium | LI2 names unclassifiable docs and publishes precision on a labelled sample before the catalogue goes live. |
| Contract enforcement on live planes refuses a writer mid-flight | possible x high | LI4 derives contracts from the current planes first (zero refusals at birth) and tightens by declaration. |
On these two registers. Rows are declared in the domain's plan file and carry the debt id, which is the join key back to the sovereign debt plane — that plane, not this page, is the authority on state. Reconciling them automatically (the regen reading the plane and refreshing these rows) is a named, owed rung; until it lands, treat an id here as a pointer to look up, not a status to trust.
Honest verdict. The coverage above is capability presence measured against source — not depth, scale, or polish, where mature rivals may lead. Exceeds are claimed only where a mechanism backs them. Every open gap is a watch contract: it names the organ and symbol that closes it, and this page flips the cell itself when that workstream ships.
