fix(lib): no Inf/NaN scores, every export documented, ECHIDNA receipt check, dead sources removed - #71
Merged
Conversation
…es removed - value_score: a zero target on Profit / Efficiency(:computation_time, :kaldor_hicks) now throws ArgumentError instead of returning Inf/NaN. Profit() defaults to target = 0.0, so the default value silently fed Inf into weighted_score, dominated and pareto_frontier. - value_score(::Fairness): a zero threshold demands exact parity (1.0 or 0.0) instead of 0/0 = NaN; :protected_attributes is accepted when :protected is absent, as satisfy and maximize already did. - Docstrings for all 27 previously undocumented exports, ported from the dead fairness_nodocs.jl where they existed and reconciled with the live TPR/FPR logic. verify_value is described as what it is: an attestation check, not a prover. maximize is described as evaluating, not searching. - Module docstring example corrected: as written its @Assert failed (disparity 0.15 > 0.05). - Remove src/fairness.jl.backup, src/fairness_minimal.jl, src/fairness_nodocs.jl (never included; the repo's own Dustfile asked for their removal) and the root scratch file test_load.jl. - Drop the unused LinearAlgebra dependency; compat julia = "1.10" (the lowest version CI tests) and Statistics = "1"; version 0.1.1. - Tests: new test/hardening.jl (zero targets, zero threshold, the :protected_attributes alias, docstring coverage with a positive control, the module example). The Safety attestation test no longer prints "Formally verified" into CI output; it captures the log line. Verified: Pkg.test() passes on Julia 1.10.10 and 1.12.6 (206 + 15 tests); examples/basic_usage.jl runs; no method ambiguities. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…-score note - verify_receipt(value, receipt; goal, allow_axioms): strict check of a parsed echidna.prove.result/1 object (`echidna prove --output json`). Malformed receipts throw; true only for status "verified", a named prover, no unaccepted trust.axioms (sorry/Admitted/postulate...) and, when given, a matching goal. String- or Symbol-keyed parses both work; no JSON or ECHIDNA dependency is added. verify_value delegates to it when handed a receipt. Follows echidna docs/PROVE-RESULT-CONTRACT.adoc and the factive/non-factive split of hyperpolymath/epistemic-types. - safety_verdict(::Safety, state) -> :entailed / :refuted / :unresolved, so absent safety evidence is no longer indistinguishable from "safe". Vocabulary from hyperpolymath/ResidualEvidenceTypes.jl (no dependency). satisfy(::Safety) is unchanged and documents its absent-means-safe default. - weighted_score docstring: the scalarisation is lossy (no section; see no-section-of-collapsing-map in hyperpolymath/echo-types) and lets one value compensate for another; a test exhibits two distinct profiles with the same score that pareto comparison still separates. Verified: Pkg.test() passes on Julia 1.10.10 and 1.12.6 (206 + 43); no method ambiguities or unbound type parameters. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

- Around line 427-430: Update the safety-flag validation in the flags loop so it
checks whether each key is present in state separately from whether its value is
a Bool; throw ArgumentError when a supplied :is_safe or :invariant_holds value
is nothing, while continuing to allow absent keys.
- Line 344: Update _is_receipt to detect whether proof contains the "schema" or
:schema key, regardless of its value; route such proofs to receipt validation so
unsupported schema values are rejected instead of falling through to legacy
attestation.

Reject a present null safety flag.
If state contains :is_safe => nothing, the current guard accepts it as unresolved. This violates the documented ArgumentError for supplied non-Bool values. Check key presence separately from value validity.
