Aliases: entry point; routing; AMem; retrieval; context; source of truth.
A section is a semantic unit. Keep its scope, qualifications and related IDs together. In AMem, resolve the current rust.chainable-stories.index state-key with filterKinds: ["pattern"], or recall RUSTCSINDEX with the Pattern filter, Commons included and full bodies. Inspect the returned current record IDs. For a section use a contiguous alias such as RUSTCS07; punctuation-split CS-07 is unreliable in the current tokenizer. Verify version/source hashes, and follow replacement lineage rather than relying on an old hard-coded record ID. If an excerpt seems absolute, retrieve its related sections before inventing an exception.
For a task, start with CS-01–CS-04, then retrieve the sections governing the actual change. Do not load every lesson or reference implementation merely because it exists. Record a material unresolved decision in the project's existing workflow; this doctrine does not demand a new document for every edit.
