Keys (spec/02 §2.4), the rule paperstack settled on:
- A work key is a Scholar-style citation key, a hyphen and the first four
Crockford base32 characters of SHA-256("scienting-key/1:" + identity),
where the identity is the first of doi, arxiv, isbn, pmid, pmcid and
openalex in same_as, else the folded title, year and family name. A
collision lengthens the later key by two characters; a key is minted
once and never recomputed. A document key adds .si, .v<seq> or .<type>
for versions other than the version of record.
- Every fixture key is now minted (hale2026harmonic-damb,
okafor2025solvent-acth, writer2027fixed-ynr7.v3, tiny2026tiny-j4qm), so
every node and record ID was re-minted and the docs rewritten to match.
The validator checks the document key against the work key and version
(doc.key.work) and the hash part against the identifier (doc.key.suffix).
vectors/keys.jsonl pins the cases paperstack's tests pin.
Review:
- Spot-check seeds are ECVRF-EDWARDS25519-SHA512-TAI proofs (RFC 9381),
implemented in tools/oracle/vrf.py in plain Python and reproduced
against the RFC's Example 16; the sample ranks by the VRF output. The
earlier Ed25519 seed could be ground by a dishonest checker.
- RFC 9162 inclusion and consistency proofs (crypto.inclusion_path,
verify_inclusion, consistency_proof, verify_consistency) with
scienting-proof/1, vectors/proofs.jsonl and two fixture records.
- document.json carries `history`, the root over the corrections, with
the empty-tree hash for none (spec/11 §11.5, rule doc.history).
- A provisional transparency log (spec/23): log entries, signed-note
checkpoints with key hashes as transparency logs share them, the rule
that a logged revocation beats a self-asserted time, and vectors.
- Reserved signature schemes cose and ml-dsa-65 (spec/08 §8.4).
Identifiers and text:
- urn:scienting: becomes tag:scient.ing,2026: (RFC 4151), since the URN
namespace was never registered.
- Unicode 16.0 is pinned for normalization and categories (spec/01 §1.4);
the checker refuses another version.
Checking:
- check.py: keys, proofs, VRF and checkpoint vectors; the proof and
checkpoint records; a check that every ID and hash the prose quotes
exists in the fixtures or vectors; three more broken packages
(history-wrong, key-suffix, key-work).
- stress.py: key, VRF, proof and checkpoint properties.
- Docs: a keys section in the concepts and FAQ, rationale entries for
keys, VRF, proofs, tag URIs and the Unicode pin, a "Looking ahead"
section, media-type registration and OCI distribution notes.

Fixture sources
Each source describes a document as a converter first read it, mistakes included, in a shorthand that tools/build.py expands.
The build mints IDs, applies the listed corrections, lays out synthetic geometry, signs the listed receipts and writes the package.
The shorthand is tooling, not a format.
| Shorthand | Becomes |
|---|---|
{"p": [...]} |
A paragraph of the listed sentences. |
{"s": [...]} |
A sentence; a string part is a text run. |
{"sup": t}, {"sub": t}, {"em": t} |
A styled text run. |
{"m": src}, {"t": src} |
A TeX or Typst math run. |
{"cite": [...], "text": t}, {"xref": target, "text": t}, {"fn": name, "text": t} |
Citation, cross-reference and footnote-mark runs. |
{"eq": {...}} |
A display equation inside the sentence. |
{"row": [...]}, {"c": [...]} |
A table row, and a cell with role, rowspan, colspan and col. |
"name": "@x" |
A local name, replaced by the minted ID; ext:<doc>:@x names a node of another source. |
"page": n |
The page the node and its descendants are laid out on. |
corrections lists the operations in order, naming nodes by local name; crop names the node whose crop is the evidence.
anchors_at_rev0 lists the anchors whose resolution vectors/resolve.jsonl records, and receipts the receipts, spot-checks and revocations to sign.
