The README listed 11 of fold's 17 detectors, never explained the
confidence tiers every finding carries, did not mention the new exit
code 2 / coverage reporting, and spent half its length on a
performance roadmap.
It now says what fold is, defines the five tiers (from
include/fold/report/finding.hpp, including concrete-witness and
latent), what "bounded" means after the loop-exit fix, a quick start,
output formats and exit codes (0 none, 1 any unsuppressed finding, 2
unwritable report or any unanalysed translation unit), and links. The
detector list defers to the complete table in docs/USAGE.md.
The performance section moves to docs/architecture/performance.md, with
one correction: the gold set was derived from fold's own reviewed output
and is matched by detector kind and file, so it catches drift rather
than measuring precision/recall independently. The lint pre-commit hook
note moves to BUILD.md.
- skills/fold-sast: rename to skill-fold-sast and expand the scan/precision
guidance for C++/Rust/Swift lanes
- docs/architecture: record call-graph phase decomposition and the
optimization-loop TP/FP/TN/FN evidence policy
- docs/mcp-tools + README: update budget/per-query defaults (1800s/6000ms)
and note the OpenGrep pre-push hook
