R77.F2 Verification — 10 section index.md stubs

File existence (10/10)

All 10 new index.md files confirmed present with valid YAML frontmatter (title + tags + type: section-index + updated):

#	Path	title:
1	docs/3-world/physics/laws/index.md	Laws (physics layer)
2	docs/architecture/index.md	Architecture
3	docs/architecture/decisions/index.md	Architecture Decision Records
4	docs/agents/index.md	Agent Contracts
5	docs/reference/index.md	Reference
6	docs/reference/extractions/index.md	Heritage Extractions
7	docs/audits/index.md	Audits
8	docs/contracts/index.md	Contracts
9	docs/packets/index.md	Packets
10	docs/verification/index.md	Verifications

Every file matches the repo-consistent section-index pattern (same frontmatter shape as the 6 pre-existing index.md files in docs/). No nav_order/parent/has_children introduced (repo convention).

Gate results

Gate	Command	Result
Build	npm run build	PASS — tsc clean
Lint	npm run lint	PASS — eslint src clean
Test	npm test	1084 / 1085 passing (26 suites)

The single failing test (startup — subprocess smoke › tsx src/server.ts boots and logs [Startup] Phase 1) is the pre-existing known flake documented in memory as predating Wave H and not a regression from this PR — which touches zero src/ files, only docs/*.md. The test count matches the post-Wave-I baseline (1084 passing).

Post-merge validation (Sigma)

After merge + Pages rebuild (~60–90 s), curl should return 200 for each of the 10 folder URLs that previously returned 404. Example checklist for Sigma:

for p in 3-world/physics/laws architecture architecture/decisions \
         agents reference reference/extractions \
         audits contracts packets verification; do
  code=$(curl -s -o /dev/null -w "%{http_code}" \
    "https://lasteld.github.io/AMS/${p}/")
  echo "${code}  ${p}/"
done

All 10 should return 200.
