bitty-perf

Independent performance validation suite for Bitty (W-105 relocation, bitty CTX-0931). Read AGENTS and TODO.

• Suite: crates/bitty-perf — headless, bounded performance baseline harness (startup/latency/idle/real-window/real-soak/throughput-floor/ typical-session/dogfood-session modules, evidence and regression tests, committed baselines under crates/bitty-perf/baselines/). Benchmark binaries live under benches/. Vendored production corpus fixtures live under fixtures/ (see fixtures/README.md for provenance).
• Tested production revision: the pinned immutable bitty commit recorded in crates/bitty-perf/Cargo.toml (W-75 pin discipline: exact commit, never a branch or tag, never a path dependency). Pin bumps are owned, reviewed changes.
• Gates: just check runs the metadata gates plus just rust-fmt, just rust-clippy, and just rust-test (bench compile/run gate and the parser-throughput regression floor against the pinned revision). The bitty product change path keeps thin required invocations of this suite (bench gate, parser-throughput floor) against the pinned suite revision.
• This repository is publish = false tooling with no shipped runtime authority; an independent repository is not an independent gate.

Prerequisite: W-75 / bitty-docs CTX-0265, Issue #404, and W-105 Core CTX-0931. Preserve baseline provenance, budget gates and reproducibility; pin production revisions.

CTX-0001 -> CTX-0002 -> CTX-0003 -> CTX-0004 maps to Issues #4 -> #3 -> #2 -> #1. CTX-0001 (bootstrap) is complete: metadata gates, independent review, first publication, redacted CarryCtx snapshot and branch protection are recorded. Suite migration is proposed under CTX-0003; acceptance (including CTX-0004 independent verification) belongs to the owning tasks.
