v0.12.90: @newsroom.writer: SGit × Ruflo, checked against the author's code

Mondweep Chakravorty published the code behind his video, mondweep/sgit-ruv-memory (MIT), and the three SGit × Ruflo articles and the walkthrough page now read from the video and the code together.

What the code settles: the ABP rows are compiled into Ruflo rules and every adapter tool is checked by a pinned copy of Ruflo's policy evaluator in enforce mode, so the pieces no longer say Ruflo's policy engine was unused (what is unused is Ruflo's running policy state); in step 11 the tampered checkpoint is refused by the adapter's digest check of the stored ciphertext, before SGit decrypts; each checkpoint is its own SGit vault and no remote push is performed; the encrypted manifest binds the ABP and compiled-rule hashes, which the author notes are not signatures. The policy piece now quotes the author's own statement of the limit, "Only adapter tools pass through this gate", gives his follow-up, native plugin registration, as the fix, and answers the five open questions from the code. The walkthrough adds the repository, its 16 tests and the keyword-recall validation. The page marks six steps "Confirmed in the code", and the component map, the step 2 and step 11 diagrams and the gap figure are redrawn.
