From 25713f6f0a2197c9ef0dfffbb60c82b6e72ca2d2 Mon Sep 17 00:00:00 2001 From: "Perplexity Computer (LEAD)" Date: Sat, 2 May 2026 20:47:35 +0000 Subject: [PATCH] =?UTF-8?q?feat(crates):=20trios-igla-ops=20=E2=80=94=20O(?= =?UTF-8?q?1)=20operator=20utilities?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Three Rust binaries replacing ad-hoc Python/shell scripts (R1: trios#143 Rust-only). fleet-probe — parallel auth+health check across all 7 Railway accounts in a single tokio fan-out (1 GraphQL call per account, ~1 s wall clock). queue-stats — single Neon connection, mission report: strategy_queue counts, running-rows-by-lane, active scarabs, best-BPB leaderboard top-15. queue-victory-hunt — idempotent insert of the full WAVE-GF-001 victory hunt grid (LR8 × hidden6 × Fibonacci F17..F21 × runnable formats binary32/GF16) = 480 canonical rows. ON CONFLICT DO NOTHING. Modules: accounts.rs — canonical 7-account registry (tokens via env vars RAILWAY_TOKEN_ACC{0..6}; never hardcoded). Lane mapping per trios#445. SANCTIONED_SEEDS = Fibonacci F17..F21. neon.rs — strip_channel_binding helper (rustls 0.23 cannot satisfy SCRAM-PLUS, see trios-trainer-igla#84) + idempotent CryptoProvider install + connect() wrapper. All canon_names produced by these tools follow the trios-trainer-igla#93 spec: IGLA-{LANE}-{format}-h{H}-LR{LR4}-rng{SEED}-{TAG} where {format} is mandatory and drawn from the 60+ format catalog (see zig-golden-float#69). Verification: - cargo test -p trios-igla-ops --lib → 3/3 GREEN (strip_channel_binding unit tests). - cargo build --release -p trios-igla-ops → all three binaries build clean. - queue-stats smoke run against live Neon DSN-A reports 493 pending IGLA-* rows, 30 running, 9 IGLA-RAILWAY-* scarabs all heart-beating.
