Bulk serial validator

Paste @U Base85 serials or deserialized lines (pipes + part tokens like 261, 0, 1, 50| 2, 2730|| …). Deserialized text is normalized on this page and decoded with the same inline WASM path as legacy/bl4-bulk-decoder.html (no iframe). YAML/JSON with serial: fields work too. Each row gets part resolution, then checked with the same data-backed rules as Legit Builder (manifest, NCS, inv composition tags from inv_comp_tag_data.js + tag-comp-validation.js, loot schedules, weights, source tables, stats coverage). Parts not on the manifest loot-pool export are listed as FYI only (rewards/vendors/quests are still valid). Drop hints use SOURCE_PATHS_DATA when applicable.

Idle. Natural legitimacy: OK means the serial can occur in-game (strict slot-map + inv tags + elements/pearl/frame + weights/schedule). Parts outside the item map, unique/licensed conflicts, 0% weight, or below MinGameStage → Fail. Soft uni_/leg_ dep gaps alone stay FYI.

How it works

Decode: Serials are decoded in this page (same engine as the bulk decoder). Paste @U… lines or deserialized forms.
OK (data): Composition looks naturally possible under our balance rules — close to save-editor.be’s Balance Pass. Not a promise that a specific boss dropped this exact roll. Quest/vendor/mail gear can still be OK even if Drop hint is empty.
Fail / Balance Fail (Modded): Hard problems such as wrong-root weapon parts (e.g. Ripper parts on a Maliwan gun), exact duplicate part keys in a slot, inv exclusion clashes (incl. unique/licensed), over-max slot counts, element/pearl/frame conflicts, and clear NCS base-map breaches. Shared ClassMod / Shield / Grenade / Enhancement / Weapon pools are allowed.
FYI (does not Fail by itself): Soft uni_/leg_ and most other dependency gaps (only missing licensed/unique hard-fail), NCS part-order noise, loot weight 0%, MinGameStage, under-min slot counts, barrel_01/02 structure tags, and most “not in our option list” gaps. Those may still show in Notes.
Drop hint: Legendary shiny / pool path hint. Modded here is visibility only — it does not flip OK→Fail. Use KPI OK + drop Modded when you want editor/off-pool gear that still passes composition.
Notes: Actionable failure lines (exclusions, duplicates, wrong-root, etc.), not the footer stats block.
Export: JSON / CSV / Markdown summaries, plus quick lists: OK only, non-OK, Fail only, or OK+drop Modded. Optional “export only rows matching filter.”

Summary

Use Notes for the real fail reasons (exclusions, duplicates, wrong-root, etc.). Drop hint is separate from OK/Fail.

Serials 0

Dup lines merged 0

Decoded OK 0

OK (data) 0

Uncertain 0

Decode failed 0

No manifest 0

Fail (data) 0

Drop hint Modded 0

OK + drop Modded 0

What do these mean?

Serials: How many rows ran (after default dedupe of identical serial text).
Dup lines merged: How many extra input lines were dropped because they repeated the same serial string. Use Keep duplicate lines to validate every line; then this shows —.
Decoded OK: WASM successfully decoded the serial. If this is less than Serials, some input couldn’t be parsed.
OK (data): Balance / natural composition pass (wrong-root, duplicates, exclusions, over-max, etc. clear). Soft FYI lines may still appear in Notes. Not a guarantee of a specific boss drop.
Uncertain: Decoded but not a clear OK or Fail — often unmapped without a hard critical rule, or warn-state only.
Decode failed: Couldn’t decode — see Notes for the error (corrupt/truncated/@U). Filter “Failures” to find them.
No manifest: Decoded but manufacturer/item type don’t match any known item type we validate.
Fail (data): Hard composition fail — often labeled Balance Fail (Modded) with buckets (Critical Rules, Tag Exclusion, …). Includes wrong-root weapon parts, exact duplicates, exclusion clashes, over-max stacks, element/pearl/frame issues.
Drop hint Modded: No legendary shiny / pool path hint. Common for quests, vendors, mail, or editor items. Does not by itself change OK/Fail.
OK + drop Modded: Passed composition (OK) but Drop hint is Modded — useful when filtering editor/off-pool gear that still passes balance checks.
