Distinguish unretained blocks from empty relations and page generated control dependencies over one lazy snapshot index. Verify all 2,845 SQLite triples through both real MCP adapters and an independent finite-path oracle; 82 related tests pass. Record equivalent core-query and process-family costs. Freeze the shared two-level controller question and oracle before real-model launches.

Investigate sqlite3VdbeExec in {{artifact_path}} statically, starting from:
|
|
- cannot open savepoint - SQL statements in progress
|
|
- cannot release savepoint - SQL statements in progress
|
|
|
|
Establish the format-owning implementation despite same-name callable entries.
|
|
Reuse one retained VM capture and selected structured facts. Locate the shared
|
|
recovered error CALL, the block containing it, and the PHI alternatives for its
|
|
format argument, including each incoming edge binding and passing storage.
|
|
|
|
For that shared-call block, obtain the complete direct control-dependence set
|
|
in the retained recovered CFG. Then obtain the direct controllers of each of
|
|
those controller blocks: exactly one additional level, not a transitive closure.
|
|
Keep the two levels separate. For every conditional controller in these sets,
|
|
report its branch operation, both successor-edge IDs/destinations/polarities,
|
|
condition identity/test, and Boolean definition. Trace operands to constants
|
|
and LOAD boundaries, preserving SSA identity, input indexes, widths and signedness.
|
|
Which conditions share exactly the same loaded SSA value? Are matching storage
|
|
coordinates enough to equate the other loaded values?
|
|
|
|
Explain the alternative guard combinations in this local two-level fragment.
|
|
Does the list of control-dependence relations mean that all listed predicates
|
|
must hold simultaneously? Use the recovered value identities and edge choices
|
|
to support the answer; do not claim these are all earlier runtime conditions.
|
|
|
|
For each direct controller of the shared-call block, supply one recovered-edge
|
|
witness from the selected successor to that block, and one from the alternative
|
|
successor to any recovered zero-successor exit that avoids the shared-call block.
|
|
Give block sequences and edge IDs. Any valid witnesses suffice; shortest paths
|
|
are unnecessary. These graph paths do not prove runtime feasibility.
|
|
|
|
Check the four selected guard sites, relevant load/spill instructions, format
|
|
setups and shared machine CALL with focused instruction windows. Separate native
|
|
optimized edge polarity/origins from actual machine branch transfers. Keep the
|
|
answer focused with real Evidence IDs, target digest and explicit recovered-graph,
|
|
alias, machine-flow, nontermination and runtime limits. Complete retained Evidence
|
|
remains available; do not return the complete C report or graph. Close the lease.
