* fix(fields): field writes keep every number's literal, so an integer above 2^53 is no longer rounded by a write that never named it (BUG-3202) Every door that writes an item's fields decoded the blob into map[string]any, turning each JSON number into a float64, so the re-encode rounded integers above 2^53 (9007199254740993 stored as ...992). The stored blob was decoded that way too, so a fields_patch to `status` rewrote every large integer in the row. - models.DecodeFieldsJSON / DecodeJSONKeepingNumbers decode with UseNumber. They accept and refuse exactly what json.Unmarshal does (trailing data, out-of-float64-range numbers); only the representation changes. - Used at every fields decode that feeds a write: create, full-fields update, the fields object on the wire, fields_patch (request and store merge), the carried-blank-relation normalisation, the Append/Set metadata helpers, move, bulk move, cross-workspace copy and its preflight, and the move/copy field_overrides (models.FieldValues). - items.validateFieldType accepts a json.Number that parses as a finite number. items.coerceValue and the CLI's parseFieldFlag keep a numeric string that is a JSON number literal as that literal. - Read-only decoders are unchanged (display, hydration, guards). Claude-Session: https://claude.ai/code/session_01A3rXV7GDLAhBe9mL4V6z2m * fix(fields): compare field values by value, so an equal number in another spelling is no change and two integers that share a float64 are (BUG-3202) Field writes now keep a number's literal, so one value can be stored as different text (1e3 vs 1000). Three places compared field values: - item.updated's change detector compared the fields blob's TEXT whenever it was not masking a string done key: an equal-value rewrite, or a key-reorder-only rewrite, emitted item.updated. - the activity `changes` diff and the BUG-3163 carry check compared float64s: equal spellings were fine, but two different integers above 2^53 compared equal, so such a change went unrecorded and a changed reserved value passed as carried. models.CanonicalJSONNumbers gives every number one exact canonical spelling. All three decode keeping literals and compare canonical forms. Claude-Session: https://claude.ai/code/session_01A3rXV7GDLAhBe9mL4V6z2m
