Lh Basis Foundation

Use when porting LinkedIn identity resolution, runtime type-guard kernels, or automation-domain payload validation — Linked Helper v2 domain-kernel contracts: person/organization/chat/message external-identifier families with hash→memberId decoding, guard-composition data models without classes, property+method-surface aggregate duck-typing, recursive message-template node validators, polymorphic list-payload guards, cross-layer DB collision error mining, source-conditional collect-info schema, interval/credit-limit guards, presence/absence discriminator pairs for campaign/action/result family splits with postpone-reason tagged unions, positional-trap CSV-import rejection taxonomies, signed result-status domains, and getDay()-compatible week-working schedule maps.

LH Basis (Linked Helper v2.130.5 ingest): Domain-Kernel Foundation

Foundation contract

This is a cold, source-specific foundation, not an operational procedure. It is historical, revision-pinned evidence rather than timeless guidance. Current project source, tests, requirements, and runtime behavior outrank this projection and decide what ships.

Provenance and revision

Source record: lh-basis; portable upstream identity, license, coverage caveats, and retrieval history are preserved in the index.
Recorded revision: ?@? (non-Git curated source).
Full provenance, coverage caveats, boundaries, and preserved evidence: references/index.md.

Topic map

Representative topics: Identity type algebra; Hash id decoding; Guard kernel composition; Template node tree; List payload shapes; Collision error mining; Source-scoped schemas; Organization identifiers.
Scope and retrieval questions: references/index.md#use-this-for.
Complete capsule chooser: references/index.md#load-the-matching-source-dump.
Detailed grouped map: references/index.md#capsule-map.
Source limitations and portability boundaries: references/index.md#boundaries.

Retrieval

Open the index, choose one capsule matching the active question, and load only that capsule. Revalidate its cited source and revision before relying on it. Do not bulk-load the inventory, treat historical claims as current truth, or apply this foundation as a procedure.
