Implemented the portable verification baseline and completed the first Resource three-tier pass.

Clone Portability

Added fresh-clone setup instructions using repository-local .venv in README.md (line 28) and tools/README.md (line 12).
Documented that any virtual-environment path works and activation is optional.
Added .venv/ and venv/ to .gitignore (line 17).
Confirmed no tracked project files reference your specenv or rnsenv.
Verification Infrastructure

Added verify_all.py (line 1), which:
Enforces versions from tools/requirements.txt.
Runs every verifier independently.
Summarizes all failures.
Confirmed it rejects the older RNS 1.1.3/LXMF 0.9.3 environment.
Resource Audit

Added Tier 1 report: resource-tier1-rns-1.2.4.md (line 1).
Added verify_resource.py (line 1).
Corrected §10 and stale flow documentation:
Direct LXMF Resource threshold is 319 bytes.
Advertisement d is total logical-resource size.
Resource packets contain slices of one encrypted stream.
Exhausted requests can also request parts.
RESOURCE_RCL rejects advertisements; ordinary receiver cancellation is local-only.
Validation:

Passed: 16
Failed: 0
ALL VERIFIERS PASS
Remaining Resource work is deterministic resources.json vectors and negative/rejection cases.
