M7 — Production Hygiene	CI Gates & Release	(CI file)	✅ live
M8 — Capstone	Assemble the Mini Service	your repo	guided build

Also on lms.codecora.dev → course Rust Foundations (CodeCora Engineering Track) (private; login required): the same pilot content as structured chapters with enrollment tracking.

Capstone follow-ups (post-course, pick your depth)

crates/search — M3 engine behind a trait, indexing the notes table
crates/ingest — M4 semaphore + JoinSet bulk loader
Postgres backend — swap connect options, keep every query pattern
Axum middleware layer — rate limiting + request IDs (Sinau’s hardening pattern)

House rules recap

Tested means live: green tests + behaving binary, not just “it compiles”.
The loop: cargo fmt && cargo clippy --all-targets -- -D warnings && cargo test.
No unsafe, no unwrap() on user input in production paths.
One error enum per crate; render status codes at the boundary only.
Backpressure or it didn’t happen: cap concurrency before spawning.
English artifacts, versioned schema, CI gates everything.
