+# Existing source-7 constructor defaults
+
+Compatibility experiment, not proposed grammar. `probe.rs` imports only the
+matching existing `oa_core` rlib; it performs no production or Cargo edits.
+
+In a coordinated direct-rustc writer slot:
+
+```powershell
+. .local/toolchain/env.ps1
+rustc --edition 2024 -D warnings --crate-name constructor_defaults_probe harness/experiments/constructor-defaults-20260911/probe.rs --extern oa_core=.local/target-gnullvm/debug/deps/liboa_core-3e81c616fea1d901.rlib -L dependency=.local/target-gnullvm/debug/deps -C linker=clang.exe -o .local/constructor-defaults-20260911/probe.exe
+& .local/constructor-defaults-20260911/probe.exe NEW_ISOLATED_OUTPUT_DIRECTORY
+```
+
+Use a fresh output directory when reproducing so the committed evidence is not
+overwritten. The rlib SHA256 is
+`5018A1FD7286ED9DFEDCBBF5B68B399AD5D143F2A9AAAED3078CFC934C9589C4`.
+The exact compiler, core source hashes, executable hash and result inventory
+are in `provenance.json`.
+
+`results/results.tsv` records **54 admitted explicit/omitted cases** and
+**12 missing-required-field refusals**, covering both OA and SA source 7.
+Every admitted occurrence is compared with a literal expected typed body and
+the full explicit-case Project. It also requires exact source retention on
+stabilization/no-op, a name-only patch retaining omissions, and canonical
+format/reparse equality. Both scenario viewpoint omission cases separately
+require MixedLegacy equality and canonical stability.
+
+The `.canonical.arcadia` siblings intentionally expand hydrated defaults;
+they are not expected to retain authored omission. Exchange `operation none`
+is deliberately omitted by canonical serialization. Files named
+`omit-bindings`, `omit-kind`, `omit-operator`, `omit-branches`, `omit-guard`, or
+`omit-occurrences` are **expected invalid fixtures**, retained to show the
+specific missing-field diagnostic. They are not modeling examples.
+
+The program/result files are durable evidence. The compiled executable and
+initial/final build logs remain in ignored `.local/constructor-defaults-20260911/`.
+Other constructor families and old schema versions were not exhaustively tested.
