Round a tuned threshold to 4dp so repeated nudges stay stable.

* Break body text into comparable segments: one per line, each further split on * sentence punctuation, normalized to single-spaced and trimmed.

* Remove fenced (``` ```) and inline (`` ` ``) code so tags/links inside code * are not extracted as real tags/links.

Body lines outside fenced code blocks, so a leading fence can't become a * skill's name or description.

Ensure a logical path carries a `.md` extension.

Append a `> See also [[label]]` cross-link, keeping one trailing newline.

Append a lesson to an existing playbook, keeping one trailing newline.

Apply an approved proposal to the vault, recording it as the proposer's edit.

* Build a normalized TF-IDF vector for a note's tokens — the same weighting the * semantic engine (`semantic.ts`) uses per chunk, applied here at not

Cosine of two normalized vectors = their dot product (iterate the smaller).

* Stable, collision-proof de-dupe key for a passage. JSON-encoding the * path/heading/text triple keeps the key plain text (no magic separator byte)

A gentle quadratic arc between two points — softer than a straight line.

Approximate the tokens a candidate contributes (its heading counts too).

A whitespace-collapsed, length-capped excerpt of a passage.

Find ATX headings in body order, skipping fenced (``` / ~~~) code blocks.

First non-empty body line of a note (heading marker stripped) — a fallback * display snippet for hits that have no exact match line and no semantic c

Generate a short, URL-safe, ASCII block id.

* Install a controllable `prefers-color-scheme` media query (jsdom has none). * Returns a `setDark` that flips the value and notifies listeners, so a

Drop a friendly note in the vault on its very first launch so it isn't empty.

A fresh per-channel playbook, seeded with its first lesson (a `type: skill` note).

* A note's declared frontmatter `type:`, normalized to lowercase, or undefined. * Read here (rather than via the schema module) so the graph stays a

Drop de-dupe claims older than the window so the map can't grow unbounded.
