docs: karpathy-pattern wiki built from the spec, plan, design contract and decisions ledger

kb/ is its own wiki root: 34 pages across 7 categories, index.md catalog, log.md, AGENTS.md schema layer, and raw/ holding copies of README, the spec, the 13-task plan, the design master and the SDD ledger.

Every page cross-references 3 to 6 others and all 107 wikilinks resolve except two [["list"]] artefacts inside JSON snippets in the copied plan.

Kept separate from the repository root on purpose: its generated graph lands in kb/.ua/ instead of overwriting the code graph.

+# SSE stream
+
+One POST to `/api/analyze` returns a server-sent event stream. `lib/stream.ts` frames events on the server and
+parses them in the browser, and also extracts text deltas from an OpenAI-compatible streaming response.
+
+Four named stages are reported as they happen: digesting, proposing, judging, writing. The console shows them as
+`1 of 4 · Reading the plan` style pills. A `done` frame re-enables the Analyse button; an `error` frame names the
+stage it died in, so a rejected plan reads "digesting: ..." rather than failing silently.
+
+If the browser disconnects, in-flight model fetches are aborted and the row is stored as `abandoned` or `partial`
+instead of piling ghost runs onto the analyst endpoint.
