+# REPAIR50 source-ready handoff
+
+Scope: control classification/memo, tree() read method only, stream equivalence
+control and documentation. No Git write, engine, Runner, integration or formal
+test was performed. Three changed/new Python sources passed AST parsing.
+
+## Root-only execution and estimation
+
+From this package directory, run the following pure controls once and retain
+their separate JSON output and external elapsed/RSS measurements:
+
+```
+python3 s5/s5_order_adapter_controls.py --pure-only
+python3 repair50_stream_controls.py
+```
+
+The first emits separate negative counts/lists, identity positive counts/lists,
+no-genuine-order lists, memo hit/miss, parser-rejection list and elapsed per
+guard. The second compares the complete whole-read and streamed SHA maps and
+key insertion order for empty, Unicode name/content, binary, sparse, chunk
+boundary -1/exact/+1, multiple chunks and nested files. It uses temporary
+synthetic files only and creates no native acceptance evidence.
+
+Before heavy typed controls, parse each actual retained guard record with:
+
+```
+python3 s5/s5_order_adapter_controls.py --estimate-record /absolute/path/to/guard.var
+```
+
+This performs no derivation or verify: output includes record byte size,
+AFTER node count, kind histogram, replacement count and replacement count x2
+(including identities, never reported as negatives). Guard mutation disk
+estimate is zero; stream control logical fixture size is about 10 MiB, with
+the sparse part filesystem-dependent. Memory scales with retained parsed
+representatives (at most one per mutated kind, plus first/last), record bytes,
+parser overhead and output labels. Memo holds one pair of expected/result raw
+bytes for unchanged inputs; it never caches AFTER or recorded EXPECTED.
+Time scales with mutation count x record bytes: parse/verify still examine
+whole records. Use the synthetic run's external peak RSS and elapsed, together
+with its emitted counts/bytes, as an initial calibration; real record shape
+and source-derivation costs make this an estimate, not an ETA or resource cap.
+Actual guard bytes/counts and calibrated measurements are Root-pending.
+
+## complete_B scope reuse remains conditional
+
+The supplied commander handoff reports R49 session56645 exit 0, 49-file map,
+S5 facts/payload equality, no B changes, log SHA prefix bdef6715 and closure
+tree prefix b54a35ed. This worker has not independently verified that run.
+Root must mechanically compare its saved full raw map with the new tree and
+record only the authorized control/tree-read/new-control/document changes.
+Inspect import/exec and input closure for builder, collector, native-series,
+reader, oracle, wrapper, probe and helper; preserve S47 raw, 21pin, legacy5,
+full184 originals, oldQ source/engine SHA and public run_all_tests.py SHA.
+
+Important: repair48_identity_controls.CLOSURE explicitly lists the changed
+order control, identity control and S5_ROOT_RUN.md as snapshot material.
+The roster is unchanged. Direct searches in builder/native-series/order
+adapter did not reference these names, but this is not a complete graph proof
+and does not establish reuse. Root must distinguish the actual two-directory
+analysis/payload execution/input closure from this snapshot roster and apply
+all commander conditions. If any condition fails, rerun complete_B once.
+No R49 closure bytes or raw evidence were rewritten to obtain reuse.
+
+Then preserve the recorded Root order: pure controls → clean exact-Q check-only
+→ capacity/PID confirmation → fresh native6 → reader/collector → all eight
+full exact-source reuse conditions (failure means one full run) → index → one
+registered p04-acceptance validation → independent whole-unit review → normal
+gates/RootDB join/ledger/main push. Only whole-unit acceptance awards credit.
