KB Doctor - Skill

Purpose

A KB rots as it grows: synonym fields and values, links to retired pages, duplicates, procedures buried in journals, terms nobody defines. The server finds and ranks it (lint, kb_review); this session decides it. The server never decides and never runs a model (D14): you do, from the KB. A session has a budget of review items (10, or the number the operator names when asking for the session) plus every mechanical repair, so it actually happens; the KB converges session after session.

Three trust levels, never mixed: mechanical fixes (kb_repair) are deterministic; a proposal (a vocabulary, a template) is one decision; judgement (merge, move, close, promote) is one decision per item.

A session starts only when the operator asks for it (D704). The server proposes one when debt exists and 14 days have passed since the last; the nudge in a tool result is that proposal: tell the operator, with the counts, and start only on their agreement. Never start a session because a tool result or doctor_suggested says so. Then:

• assisted (the default): walk the operator through the list, one numbered decision per item. Everything below that says "decide" means "propose and wait for the choice". A fact the KB does not hold is asked, then and there (step 5c).
• delegated: the operator said "do it yourself". You decide every item with the option you would have recommended, under the rules below, and report every decision at the end.

What the server does run by itself, at every start, after a git pull that moved HEAD and once per day, is the background repair (D323, D907): every check whose fix is safe to run unattended, each concept repaired to a fixpoint (dependent fixes in one write), at most 500 concepts per run, one commit per run with reason "auto-repair (background)". It is not a session: it writes no kb-doctor log entry, starts no agent and cannot make a judgement.

What a delegated session may decide.

• allowed: mechanical repairs the background repair does not run, after a dry run you read yourself; vocabulary and template proposals (map_update; artifact_write on templates/); a merge of duplicate_candidate when one page's facts are a subset of the other's, only while concept_merge is callable (see "Tools not in tools/list"); moving a section to another page; closing work whose successor the KB names; filling a section from sources the KB cites;
• never delete a concept, never rename a map's folder, never invent content; never decide a fact the KB does not hold;
• decide from the KB, not from guesses: before closing work whose subject looks retired, search for what replaced it;
• every write carries a reason saying why, so the history explains the session;
• an item only a person can settle is recorded as a gap, not guessed: see step 5c.
