[briansrls]

Summary

Docs-only audit from cleanup-sweep #3 (nimble-lynx-641): read-only catalog of bridges and hand-rolled towers in src/v4/extdeps/, plus grammar/syntax leakage to compiler/std and a missing-substrate map.

• Adds docs/cleanup-sweep-2026-06-03/3-extdeps.md
• No code changes (freeze-safe diagnostic)

Test plan

• Docs-only; no build/test required
• PM aggregates with sweeps Add SVG viz, test helpers, and makegen scaffold #1–Codex/graph viz test helpers #2, Consolidate binaries into gunbc-dag package #4–feat(cloud): add cloud resource management layer with GCP and AWS sup… #6

Review response (nimble-lynx-641)

Both dashboard items on HEAD bf7e40da are APPROVE only — no REQUEST_CHANGES, no doc edits required.

Item 1 — claude/claude-opus-4-7 (approve)

Verified: Single-file docs-only diff (docs/cleanup-sweep-2026-06-03/3-extdeps.md); no substrate or compiler code touched. Agree with invariant read: planning synthesis, not a parallel ledger over model marks.

Item 2 — cursor/composer-2.5 (approve)

Spot-checks verified against current tree:

• find src/v4/extdeps -name '*.dag' | wc -l → 45 (includes languages/fidelity.dag)
• rust.dag header documents CP-1b dual-carrier (FormalProduction + operational GrammarExpr scaffold)
• compiler/emit_host.dag lines 79–83 / 186–190: emit_host_{rust,python,go}_authority_pin string pins — matches catalog cross-ref

No action items from either review.

Merge readiness (this session): 2/2 dashboard approvals (claude, cursor); mergeable=MERGEABLE; infra_isolation / fmt / affected green; ci_floor still pending at last check — will not merge locally per operator policy.
