proof(#84): discharge 3.2 bounded external interaction (property)#164
Merged
Conversation
3.2 was already substantially covered in claude-client (capped saturating `backoff_delay` documented "obligation 3.2", a bounded `max_retries` retry loop, and tests `backoff_is_bounded_and_monotonic` + `user_content_cannot_inject_into_ request_json`), so proofs/README marking it "open" was an underclaim. - Add `total_retry_budget_is_finite`: the retry loop runs a bounded number of attempts and each wait is the capped backoff, so the worst-case TOTAL wait across the whole external interaction is finite and bounded (not just each individual delay) — the property that "bounded external interaction" actually asserts. Verified: claude-client 9 tests pass. - Correct the status of 3.2 to *property*-discharged in proofs/README.adoc, the Trustfile PROOF_ARTIFACTS map, and STATE.a2ml. This is the last self-contained obligation in the #84 map. Remaining OPEN are research-grade / external: 1.1 (formal ESP contraction; precondition holds), 1.2 (formal Dafny bound; property evidence exists), 2.2 (N/A single-owner), 3.1 residual (egress veto — external conative-gating #103). Ground truth: cargo test green, clippy --all-targets -- -D warnings clean, fmt clean, must-check exit 0.

Summary
Completes the last self-contained obligation in the #84 proof map.
3.2 (bounded external interaction) was already substantially covered in
claude-client— a capped, saturating
backoff_delay(documented "obligation 3.2"), a boundedmax_retriesretry loop, and testsbackoff_is_bounded_and_monotonic+user_content_cannot_inject_into_request_json— soproofs/README.adocmarking it"open" was an underclaim.
total_retry_budget_is_finite: the retry loop runs a bounded number ofattempts and each wait is the capped backoff, so the worst-case total wait across
the whole external interaction is finite and bounded — the property "bounded external
interaction" actually asserts (complements the per-delay cap test).
proofs/README.adoc, the TrustfilePROOF_ARTIFACTSmap, andSTATE.a2ml.Ground truth:
