The map compiler: dex-map writes state/map.json - #126
Merged
Conversation
One mechanical compile inverts what is already on disk — taxonomy, entity-members, corpus and wiki — into the cached artifact the query surface will read: every topic (uncategorized-shares excluded — a ledger, not a topic) with description, sorted members, count, has-page and the newest member's share date; every entity with kind, aliases and members; and a typed edge list with implicit nodes — directed wikilink edges kept only between taxonomy names, and weighted shared-items intersections for topic-topic and entity-topic pairs, each stored once, smaller name first. The bytes are deterministic — sorted names, sorted ids, fixed edge order — so a freshness check can diff a recompile against the file. A missing taxonomy or entity-members file compiles an honestly empty map; a malformed one refuses loudly with nothing written; a corpus or wiki file that will not read contributes nothing, as in serve — lint is what reports broken files. The [[wikilink]] extraction lifts out of serve/library.py into wikitext.py, THE one extraction both readers share; serve behavior is unchanged. Instance gains map_path, KNOWN_VERBS gains map, and the entry point, shim usage line and README command table move together per the standing rule.

PR1 of the instance-map stack (design: #125). The mechanical compile:
dex-mapreads taxonomy, entity-members, corpus and wiki and writesstate/map.json— every topic and entity with members, counts, has-page and newest date, plus the typed relation graph (directed wikilink edges, weighted shared-member edges). Deterministic to the byte, atomic write, loud refusal on malformed judgment files, honestly-empty map for young instances. Wikilink extraction lifted towikitext.py, shared with serve unchanged.63 tests; mutation audit run on both new modules (survivors read — all equivalent).
