  "notes": "Terminal iteration of the standalone-loop/recur milestone (codegen Component 5 + run-to-value/deep-n/infinite-build E2E). Zero review re-loops across all 3 tasks; all four Boss design calls implemented verbatim (alloca-not-hand-phi; mut_var_allocas reuse; emergent loop-exit via the if/match join; single block_terminated field + parallel SET site) — each verified against actual read source before implementation, none reopened. T1 RED observed verbatim (iter-1 lower_term stub via direct ail build); GREEN sum_to->55. T1 plan's literal codegen arms compiled as-written, no plan-vs-reality substitution needed (pre-grounding confirmed mut_var_allocas:(String,Type) + lower_term->(String,String) matched). One DONE_WITH_CONCERNS on T3: the plan's literal `cargo test --workspace tail` filter substring matches no test name (real tail-app guards live under ailang-check/-prose lib + e2e iter14e_*musttail); ran the gate via real test names + the authoritative full-suite 619/0 which subsumes them — recurring feedback_plan_pseudo_vs_reality class (verification-command filter doesn't resolve), no behaviour change, intent (tail-app/verify_tail_positions byte-unchanged) preserved. Codegen-only iter: no schema/AST/serde/typecheck change; hash pins (loop_recur+iter13a) + drift trio + carve_out_inventory green untouched (empirical proof none scans the codegen region). cargo test --workspace 616 -> 619 (= baseline + exactly the 3 new e2e tests), zero FAILED/error. Milestone structurally closed; audit/fieldtest is the Boss post-iter call."
