feat(passport): public field-level redaction (keep GETs public, hide sensitive fields) by Scottcjn · Pull Request #6833 · Scottcjn/Rustchain

Alternative to #6197 — redact sensitive fields instead of admin-gating the whole listing

#6197 puts require_admin() on every machine-passport GET. Machine passports are hardware-provenance/showcase data (the public Green-Tracker story), so blanket admin-gating throws away their public value. This keeps the GETs public but strips the genuinely-sensitive fields from the unauthenticated view; an admin-keyed request still returns the full record.

Redacted from the public view:

repair log → technician, notes, cost_rtc (private operational detail)
attestation → entropy_score
benchmark signatures → cache_timing_profile, simd_identity, thermal_curve, memory_bandwidth, compute_score, entropy_throughput — these are the raw anti-VM hardware fingerprint. Publishing them hands an attacker the exact profile to mimic, so they're admin-only. (This corrects an assumption that the passport held no fingerprint data — it does, in passport_benchmark_signatures. The tri-brain review caught the leak.)

Public still sees: name, architecture, year, photos, provenance, restoration story (repair type/description/parts), earnings stats, ownership lineage, and that a benchmark exists (timestamp) — none of which reveals a fingerprint.

Tests: 9 cases — public strips each sensitive field, admin sees the full record, listing stays 200 (keep-public preserved). 44 passed (1 pre-existing PDF-date failure unrelated).

Recommend this over #6197 — it protects the spoofing-relevant fields and miner privacy without taking the provenance showcase private. If you'd rather lock it all down, #6197 does that, but it's heavier than the threat needs.

Keeps machine-passport GETs PUBLIC (provenance/showcase, like the Green Tracker) but strips the genuinely-sensitive fields from the unauthenticated view; an admin-keyed request returns the full record. Redacted from public: - repair log: technician, notes, cost_rtc (private ops) - attestation: entropy_score (derived fingerprint summary) - benchmark signatures: cache_timing_profile, simd_identity, thermal_curve, memory_bandwidth, compute_score, entropy_throughput — these ARE the raw anti-VM hardware fingerprint, so publishing them would hand an attacker the exact profile to mimic. (Correcting an earlier assumption that the passport held no fingerprint data; it does, in passport_benchmark_signatures.) Public still sees name/arch/year/photos/provenance/restoration story/earnings stats/ownership lineage + that a benchmark exists (timestamp). Endpoints stay public (no admin gate) per the keep-GETs-public policy. 9 redaction tests (public strips, admin sees full, listing stays 200).

I reviewed the passport redaction change.

The new TestPassportPublicRedaction class is appended after the file-level if name == "main" block, and run_tests() is invoked before that class is defined. It also is not added to the explicit suite inside run_tests(). If this repository runs node/tests/test_machine_passport.py directly, the new redaction tests never execute, so the main privacy behavior added by this PR is not covered by the existing script runner.

Please move the class above run_tests()/the main block and add it to the explicit suite, or switch the file to a discovery-only runner consistently. The implementation itself is easier to trust once the new redaction paths are actually exercised by the same runner this file already defines.
