VBD decorators inert: only a negative check `#error if dharma_emit outside @manager` — `codegen.el:2929-2934`; `lang/spec/language.md:449` "decorators with structural meaning today: none". `@route(path,method,kind,suffix)` synthesizes `el_route_dispatch` — `codegen.el:3500-3852` — but only on **unmerged** `feat/el-route-decorators`. **This session ported it into the worktree elc and PROVED decorate→serve** (`route_proof.el` on :8951; `surface.el` compiles, dispatcher generated for all 8 ops). | +| **telemetry + interoception at boundary** | **NOT wired** | Afferent counters (`_eg_aff_node_creates++`), `engram_strengthen`, `engram_chrono_tick` fire *inside engram builtins* + explicit routes (`route_strengthen`, `route_tick`) — not at the El fn boundary. `cg_fn` (`codegen.el:2919`) injects zero instrumentation. | +| **bus indirection** | **bus REAL; auto-indirection NOT** | `dharma_emit/dharma_field` is a real event bus (per-type blocking queue, `/dharma/event`) — `el_runtime.c:11685-11987`. Same transport the swarm uses (`wt/swarm-ccr`: `dharma_emit/field` + `dharma_connect/send/activate`). `@manager` *may* call it (enforced) but decoration does not auto-insert it. `surface.el` calls it explicitly today (correct, compiles). | + +## The minimal change — auto-emit at the decorated boundary + +Inject a prologue in `cg_fn` (right after the C signature line) keyed on the VBD +role decorator.

A standalone El service (`route_proof.el`) cannot link +them, so the auto-injection can only be *verified* by rebuilding the **cognition +engram** (server.el + the geometry/cognition `el_runtime.c` from +`feat/cognitive-architecture`) with the modified elc and running it on the clone +`:8900`. That rebuild is a multi-branch integration + a delicate ~3.5 MB C build +(AGENTS.md warns of 27 GB OOM on folded builds). Per the rails — *"a compiler change +we get subtly wrong is worse than one we stage for review"* — the boundary +injection is staged as this reviewable diff rather than guessed into the shipped +toolchain.
