audit-engineer: intent-gated datafacts — pre-publication intent gate (problem 08)
Layer: datafacts · Problem: 08 · Persona: audit-engineer · Author: Midhun Raj Charles (midhunrajcharles) — same name as the Phase 2 skills submission ([AgentIntent in the registry](https://nandatown.projectnanda.org/skills), entry…
feat(datafacts): add MerkleDataFacts plugin with Git-style DAG, monotonic hash chains, bloom ancestry, and aliases
Implements Problem 08:
nandha-datafacts-verifier: Delegatable capability tokens …
Problem #4: Delegatable Auth (True Macaroon-style Capability Tokens)
maurathat: sic_facts — serialization-invariant content addressing (closes the provenance-laundering gap in byte-level CIDs)
TL;DR: cid_facts prevents name substitution, but not identity forking under semantically equivalent serialization. sic_facts closes that gap while preserving tamper detection and unknown-parent rejection.
hiten: add configurable provenance_supply_chain_multi scenario
This is a focused follow-up to my previous hackathon PR (#39). Following the merge of the DataFacts implementation in #31, this PR contributes the independent scenario enhancement suggested during review by introducing a configurable…
interview-integrity: Problem 08 (datafacts) — ogha_facts plugin: audience ACLs + pre-hash PII redaction + screening-evaluation scenario & validators
I run the AI services for a verified-screening business — the filter at the *front* of a client's hiring funnel. A human interviewer conducts a recorded screening interview; the audio is transcribed, and the interviewer files an evaluation…
scenarios: provenance_supply_chain_linear — deep linear provenance chain (follow-up to #35)
Follow-up #2 to #35 (closed as a duplicate of #31), the distinct-topology scenario @dhve flagged as worth landing independently.
datafacts: first-class typed parents field on DatasetMetadata (follow-up to #35)
Follow-up #1 to #35 (closed as a duplicate of #31), the typed-lineage-field piece @dhve flagged as a clean, independent improvement.
hiten: add typed FreshnessProof model
This is a focused follow-up to my previous hackathon PR (#39), implementing the reviewer-suggested FreshnessProof API improvement after the DataFacts work from #31 was merged.
feat(datafacts): implement content-addressed plugin
This PR implements Problem 08: Content-Addressed Datasets with Provenance Chains and Freshness Proofs for the NANDA Town hackathon.
