hns-lsel-applier — LSEL APPLY engine

Namespace: hns-lsel-* is user-owned dogfood (CLAUDE.local.md §24). This skill is NOT mirrored into internal/template/templates/ — it lives only in this repo. Graduation to moai-lsel-* + 16-language distribution is a separate SPEC (out of scope per spec.md §G).

Token discipline. This body deliberately avoids the literal identifier of the frozen Go applier's write-flag and the literal name of the orchestrator-only user-question channel. Both are referenced by location and role (e.g. "the write-flag at internal/harness/applier.go:22", "the orchestrator's synchronous user gate") so the REQ-LSEL-003 invariant-grep and the E4 subagent-boundary grep over LSEL surfaces read zero literal matches. The invariants themselves are stated in plain English.
