+- [x] **\[feature\]** `ail emit-ir --emit=staticlib` — restore the
   Decision-5 IR-readability affordance for kernels (M1 fieldtest
-  spec_gap). DESIGN.md Decision 5 makes "the compiler emits LLVM IR
-  as text so the LLM can read what it generated" a load-bearing
-  author affordance, but `ail emit-ir` has no `--emit=staticlib`
-  (only `ail build` does), and `emit-ir` on a `main`-free kernel
-  hits the executable-path `MissingEntryMain` rejection — so the
-  author cannot read the generated `@<sym>` forwarder for an
-  exported kernel, the exact thing M1 introduced. Resolution chosen
-  on the merits: **add** `--emit=staticlib` to `ail emit-ir`
-  (symmetric with `ail build`, reusing the `Target::StaticLib`
-  path) — NOT narrow DESIGN.md (narrowing a load-bearing affordance
-  to dodge a gap is the wrong direction). Scoped feature, no design
-  fork. P1.
+  spec_gap#2) — CLOSED 2026-05-18. `ail emit-ir` had no
+  `--emit=staticlib` (only `ail build` did) and on a `main`-free
+  kernel hit the executable-path `MissingEntryMain` rejection — an
+  author could not read the generated `@<sym>` forwarder for an
+  exported kernel. Resolution **added** (DESIGN.md *widened*, never
+  narrowed): a one-line symmetric codegen convenience
+  `lower_workspace_staticlib(ws)` routing through the M1-audited
+  unchanged `Target::StaticLib` path, an `emit` clap field on
+  `Cmd::EmitIr` symmetric with `Cmd::Build`'s, a zero-export guard
+  byte-identical to `build_staticlib`'s; DESIGN.md §"Embedding ABI
+  (M1)" affordance sentence + a CLI-synopsis correction also
+  discharging a pre-existing M1 `ail build --emit=staticlib`
+  omission. No new doc pin (E2E pins behaviour; architect's
+  milestone-close DESIGN.md read catches stale prose). Boss-verified:
+  3 new E2E 3/0 (incl. functional CLI spot-check — `@backtest_step`
+  external forwarder readable, no `@main`), `embed_staticlib_cli`
+  2/0 (build-side untouched), `docs_honesty_pin` 5/0, `ail` 186/0,
+  workspace 623→626 (+3), zero out-of-scope diff, no fixture minted.
+  Scoped feature — no audit/fieldtest gate (E2E is the coverage;
+  reuses the M1-audited codegen path, no invariant/surface change).
+  plan `docs/plans/emit-ir-staticlib.md` (`03493c9`) → iter
+  `bcfe554`. Stays here briefly for context; remove once stale (full
