-## PR-15 — Link Orchestration v0 inside `prometeu_compiler`
-
-**Why:** The compiler must emit a single closed-world executable blob.
-
-### Scope
-
-* Move all link responsibilities to `prometeu_compiler`:
-
-  * **Input:** `Vec<CompiledModule>` (in build-plan order)
-  * **Output:** `ProgramImage` (single PBS v0 bytecode blob)
-
-* Linker responsibilities (v0):
-
-  * resolve imports to exports across modules
-  * validate symbol visibility (`pub` only)
-  * assign final `FunctionTable` indices
-  * patch `CALL` opcodes to final `func_id`
-  * merge constant pools deterministically
-  * emit final PBS v0 image
-
-### Deliverables
-
-* `link(modules) -> Result<ProgramImage, LinkError>`
-* `LinkError` variants:
-
-  * unresolved import
-  * duplicate export
-  * incompatible symbol signature (if available)
-
-### Tests
-
-* `archive-pbs/test01` as integration test:
-
-  * root depends on a lib
-  * root calls into lib
-  * final blob runs successfully in VM
-
-### Acceptance
-
-* Compiler emits a single executable blob; VM performs no linking.

-## PR-16 — VM Boundary Cleanup: remove linker behavior from runtime
-
-**Why:** Runtime must be dumb and deterministic.
-
-### Scope
-
-* Audit `prometeu_core` and `prometeu_bytecode`:
-
-  * VM loads PBS v0 module
-  * VM verifies (optional) and executes
-
-* Remove or disable any linker-like behavior in runtime:
-
-  * no dependency resolution
-  * no symbol lookup by name
-  * no module graph assumptions
-
-### Deliverables
-
-* VM init path uses:
-
-  * `BytecodeLoader::load()` → `(code, const_pool, functions)`
-  * verifier as an execution gate
-
-### Tests
-
-* runtime loads and executes compiler-produced blob
-
-### Acceptance
-
-* Linking is fully compiler-owned.

 ## PR-17 — Diagnostics UX: dependency graph and resolution trace
 
 **Why:** Dependency failures must be explainable.
