alexmandClaude 3831b52a2b feat: ML-DSA-65, did:key, named hash algorithm, model provenance, log tiles and witnesses
- hashing.algorithm names the hash function in every document; a consumer refuses one it does not implement (doc.hash.algorithm)
- ML-DSA-65 (FIPS 204) is an implemented signature scheme: pure-Python reference in tools/oracle/mldsa.py checked against NIST ACVP vectors, a receipt signed by the new roster key dana, and signature vectors for key generation and a deterministic signature
- roster keys may carry a did:key, which the validator checks against the public key (doc.roster.did), and a witness purpose for parties that cosign log checkpoints
- model provenance: a correction's author and an annotation's generator name the model with provider, version and the hashes of its weights, prompt and parameters, and where it ran
- the transparency log gains the tlog-tiles static layout (fixtures/records/log/), a project settings.log with origin, witnesses and threshold, and an acceptance rule; the fixture checkpoint is cosigned by a witness
- store.sql: roster_keys accepts cose and ml-dsa-65 and gains a did column
- spec chapters 01, 08, 11, 18, 20 and 23, the rationale, glossary, fixture, vector and tool guides updated; stress harness covers ML-DSA

The paperspec specification

This specification states exactly what each paperspec file holds and how every value in it is computed. The schemas, SQL, JSON-LD context, registries, vectors and fixtures are normative too, and each chapter says which of them it relies on. A chapter and a vector that disagree signal a bug, so please report it in the repository, https://git.scient.ing/infra/paperspec.

Two readers will get the most from it: implementers who build a reader, writer, converter or checker, and experts who want the precise rules. Newcomers should start with the guides, which explain what the formats are for. This text assumes you know why and tells you how.

Reading paths

Find the row for the job you are doing and read its chapters after those in the first row. Chapter numbers are those in the table below.

If you are writing Read
Anything at all 0, 1, 3, 4 and 5: introduction, conventions, nodes, identity and the content values.
A reader of packages Then 2, 6, 7 and 12: the model, anchors, geometry and the package.
A converter Then 9, 10 and 11: figures and tables, references, and corrections with the gate.
A store or a server Then 8, 13, 14 and 23: receipts, the database form, rights, and the transparency log.
A writer or reader of annotation, teaching or data files Then 15 to 21.
A validator Chapter 22, with registry/rules.json.

Chapters

Chapter Subject
0. Introduction Scope, conformance, versions and status, and how the repository is arranged

2. Works, versions, witnesses and documents The four objects; document.json and witnesses.json
3. Nodes Nodes, their kinds and children, content, attributes, inline runs and the plain projection
4. Identity Minting IDs, permanence, retirement, aliases, ids.jsonl, store-qualified names and record IDs
5. Content values The five content values, the projections, alignment, suspects, keyed hashes and the metadata hash
6. Addresses and anchors Addresses, anchors and the five resolutions, with drift
7. Geometry Page fingerprints, stamp rules, pages.jsonl and locations.jsonl
8. Fidelity, receipts and spot-checks Fidelity levels, receipts, signatures, Merkle roots, the roster, revocations, spot-checks and error bounds
9. Figures, tables and equations Figures, panels, tables, cells and equations

13. The database form and the bundle The database form and the SQLite bundle
14. Rights Rights records, policies, stages and backends
15. Datasets Frictionless Data Packages with units, uncertainty and origin; anchors.jsonl; content hash
16. Digitization records How values were read off a figure panel: target, axes, series, method, verification and confirmation
17. Views Vega-Lite specifications that pin their data, and optional computations
18. Layers and annotations Layers and annotations
19. Exercises, submissions and grades Exercises, submissions and grades
20. Projects Members and roles, documents, reading paths, held layers, datasets, views and drafts, and settings
