Types phase 4 — containers. A splice-on-demand open-addressing hash table (runtime/native/dict.ludic, FNV-1a, linear probing, tombstones, grow at 0.7) behind two namespaces: - Dict.* — string -> int map: new/set/get/get_or/has/remove/size/clear/keys. Resource counts, id/name registries. O(1) average vs a linear list scan. - Set.* — set of strings: new/add/has/remove/size/clear/members. Tags, unlocked achievements, visited tiles. Shares the same table. Values are int (also an entity handle / small id); Value.* covers richer maps. [T; N] inline fixed arrays remain future work — typed buffers and []T slices already cover heap-backed arrays. Wired: parser splice trigger (g_uses_dict), emit_call dispatch, reseeded seed, a self-asserting example (examples/library/containers.ludic + feat_case), and per-symbol docs + inventory. All suites green incl. golden renders byte- identical and the bootstrap fixpoint. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

A hash map from string keys to int values — the everyday lookup a game needs, like resource counts or an id registry by name. A Dict is backed by an open-addressing hash table (FNV-1a, linear probing, tombstone deletes, growing at load factor 0.7), so get/set/has are O(1) on average rather than the linear scan a list would give. Create one with Dict.new, then set / get / get_or / has / remove / size / clear / keys. Values are int (which also holds an entity or any small id); for richer values use the Value. tree. Arguments are positional. The runtime is spliced in only when a program mentions Dict. (or Set.*).
