+# Runtime Effect Kind-8 Tier2 Recipe Runtime Note
+
+This note summarizes the checked subgraph
+`artifacts/exports/rt3-1.06/runtime-effect-kind8-tier2-recipe-runtime-subgraph.md`,
+seeded from:
+
+- `0x00435630`
+- `0x00412d70`
+- `0x00412fb0`
+
+## High-level shape
+
+The current Tier 2 recipe/runtime strip is one tightly coupled rebuild family, not a set of
+independent helpers.
+
+Important bounded relationships:
+
+- `0x00435630`
+  - rebuilds scenario-side port/warehouse cargo recipe runtime tables
+  - re-enters `0x00412d70`
+- `0x00412d70`
+  - rebuilds candidate runtime records from scenario state
+  - re-enters `0x00435630`
+  - also re-enters `0x00411ce0` and `0x00411ee0`
+- `0x00412fb0`
+  - broader collection-load owner
+  - re-enters `0x004120b0`
+  - then `0x00412d70`
+  - then `0x00412ab0`
+  - then `0x00412c10`
+
+So the current recipe/runtime strip is not a simple one-way ladder. It is a coupled rebuild loop:
+
+- recipe runtime rebuild
+- candidate runtime-record rebuild
+- per-record stream-load rebuild
+- later named-availability latch refresh
+
+## Neighboring owners
+
+The same bounded subgraph also shows the relevant downstream and side owners:
+
+- named availability / cargo-economy side:
+  - `0x00412c10`
+  - `0x0041eac0`
+  - `0x00434ea0`
+  - `0x00434f20`
+- broader load / bringup side:
+  - `0x004131f0`
+  - `0x004384d0`
+  - `0x00443a50`
+
+## Current implication
+
+This supports the current Tier 2 bias:
+
+- the shipped add-building carrier differences are more likely to live in the interaction between
+  recipe rebuild, candidate runtime-record rebuild, and later availability-latch refresh
+- not in one isolated helper or one isolated named-availability bit
+
+So the next recovery pass should target the internal sequencing and data handoff across:
+
+- `0x00435630`
+- `0x00412d70`
+- `0x00412fb0`
+- `0x00412c10`
+
+rather than returning to the title overlap or direct `Warehouse05` availability question.
