# Run the five honesty/anchor sweep-invariant greps against the
# design/contracts (the honesty-bound contract surface; design/models
# is the narrative tier, out of honesty-sweep scope); the spine is
# design/INDEX.md. Output: matched lines, prefixed by sweep name.
# Exit 0 if all five sweeps are clean, 1 if any anchor was found,
# 2 if the spine (design/INDEX.md) is not found. Sweeps 1-4 are the
# history-anchor invariants; Sweep 5 is the docs-honesty-lint
# Wunschdenken / post-mortem invariant.

# Companion to skills/audit/agents/ailang-architect.md "What you check
# / design/ history-anchor regrowth". The rationale of each sweep
# regex (Sweeps 1–4: history anchors; Sweep 5: honesty / Wunschdenken)
# lives in the design-md-consolidation milestone commits (2026-05-10).
#
# A non-zero exit is advisory, not authoritative: the architect agent
# reviews each match and decides whether it is a legitimate quote
# (e.g. a block-quote citation of a commit body) or fresh drift.
