Reads decrypt, writes encrypt, the inner backend never sees plaintext. Composes with itself (nested cubes with different keys). - cube.Pack/Unpack/Open: portable encrypted DataCube archives. Pack walks a source Medium into a tar archive, encrypts via the Sigil framework, and writes the ciphertext. Open returns an in-memory Medium over the decrypted tar for direct reads without unpacking. - Named action registry: core.io.local.read|write|list|delete, core.io.memory.read|write, core.io.copy (io.RegisterActions), core.io.cube.read|write|pack|unpack (cube.RegisterActions), and core.io.s3.read|write (s3.RegisterActions). All backends use the existing Sigil framework and core primitives (no banned imports). Tests cover Good/Bad/Ugly for every function, all 10 packages pass go build / vet / test.

Cerberus DREAD CRITICAL #1049 — ChaCha20-Poly1305 catastrophically fails under nonce reuse: leaks XOR(plaintext_a, plaintext_b) and lets an attacker recover the Poly1305 one-time key for unlimited authenticated forgeries. Production callers (cube/cube.go x4, workspace/service.go x1) all pass nil → safe. This closes the API shape that invited future deterministic-ciphertext misuse. Doc comment warns explicitly: nonce uniqueness is the invariant; if deterministic AEAD is needed, that's a future PR backed by AES-GCM-SIV.

charset=UTF-8 Content-Transfer-Encoding: 8bit NewSigil("chacha20poly1305") used to return an unkeyed ChaChaPolySigil which could never successfully encrypt — newAEAD(nil) returns "bad key length" and there was no SetKey hook to install one post-construction. Half-built factory entry: a footgun for callers who'd reasonably expect the factory to return a usable sigil. Removed the case entirely. Callers must go through NewChaChaPolySigil (key, nonce) — the only path that requires + installs key material. chacha20poly1305 import dropped (no longer used by sigils.go after #1049 landed the nonce-uniqueness invariant in crypto_sigil.go). Cerberus #1059 from workspace-wide sniff. Tests: NewSigil("hex") succeeds (sanity); NewSigil("chacha20poly1305") errors with "scheme requires key material; use NewChaChaPolySigil".

=?UTF-8?q?=20PWA=20stub=20backends=20per=20RFC=20=C2=A712=20+=20=C2=A713?= =?UTF-8?q?=20(#633)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit GitHub Medium: REST contents-backed reads via google/go-github + oauth2, recursive List, Clone action, auth via GITHUB_TOKEN env or ~/.config/lthn/github-token. Read-only mutators return ErrReadOnly. Registers core.io.github.{read,list,clone} actions. PWA Medium: stub returning ErrNotImplemented uniformly. Doc comment documents the load-bearing dep chain: forge.lthn.ai/Snider/Borg (Borg IS the PWA collector — headless-browser scraping is one of Borg's many roles; Borg also wraps the scraped artefact in a DataNode and io.Medium was designed FOR DataNodes from day 1) and forge.lthn.ai/Snider/Enchantrix (encrypts the fetched payload at rest; Trixxie is THE encryption layer for ALL encryption across the stack). Wire BOTH at canonical forge.lthn.ai/Snider/* paths when scaffolded — never migrate to dappco.re/*. go test ./... + go build ./... pass under isolated GOWORK=off (parent workspace has unrelated replacement conflicts, #1020).
