 Exact validation commands and initial/retry results are recorded in implementation.json repair17.validation. No Godot/native/full execution or recollection was performed.
 
+## Repair19 — submitted, no acceptance
+
+Input M: fd643f55a271e63c554b94681454d357117c0678. Verify-only failure:
+8ee0765cdd0a438dbf0ddc0f67ebbc70. New HEAD: **to be bound by Runner**.
+The R15 diagnosis was an unverified palette reveal followed by a possibly clipped
+button click; deferred quit also allowed requests and secondary failures after
+an ACK timeout or identity/hash failure. The Root31 ACK is invalid. R15 earns no
+credit. No acceptance or changed-source evidence reuse is claimed.
+
+Repair19 changes only the passive endpoint, additive checker gates, synthetic
+positive/negative specimens and these handoff records. Repair18 and all R09 pins
+remain history without rewriting. Runtime, product UI, the ACK deadline, spec,
+scope and denominator remain unchanged.
+
+### Source-map applicability
+
+The four changed executable/source inputs and their SHA256 at M and in the
+worktree are listed in implementation.json `repair19.source_map`. The two changed
+handoff documents are also listed there at M; their final byte SHA256 are reported
+with submission, outside the documents to avoid a self-referential hash.
+
+Read-only rg and preload/load tracing found these consumers:
+
+- docs recorder `passive_os_placement_recorder.gd:2` preloads passive_placement.gd,
+  which extends placement.gd. Its `run` drives the writer/reader OS pair.
+- `tests/ui/test_p08_normal_placement_ops.gd:2` preloads placement.gd directly.
+  That parent is unchanged by repair19; it loads main.tscn and the existing codec
+  and audio cleanup helpers. The passive subclass is not loaded by this UI suite.
+- `tools/run_p08_normal_placement.py:145,210,227` loads the checker for initial
+  input fingerprinting, OS input mapping and final evidence verification. Its
+  import/parse stages precede handler writer/reader stages using the UI suite,
+  and its OS stage uses the docs recorder.
+- `tools/test_p08_normal_placement_evidence.py:28-30,55-56` loads the checker,
+  checker_fixture.py and collector, and reads both GDScript fixture sources.
+- `tools/run_all_tests.py:roster` discovers the UI suite; `source_refs` includes
+  tests and tools in the whole-source fingerprint. Import/parse/native and final
+  regression applicability therefore requires the actual complete fingerprint.
+  The checker also imports the prior typed codec and standard runner directly.
+
+Every OS/native collection and regression whose inputs include a changed file
+is not applicable and must rerun on the final frozen revision: the complete
+p08-normal-placement OS/native pair, checker tests, the UI suite when its actual
+input fingerprint includes a changed fixture, and exactly one final all-suite
+regression on the roster Root derives at the final revision. No roster count is
+assumed. A prior native/import stage may be reused only on an exact fingerprint
+match; no reuse is claimed where source changed. The UI suite is included in the
+fresh pair and final roster regardless of its unchanged direct parent fixture.
+
+Neither completion_marker_contracts.json nor suite-policy.json changed: no pinned
+print line, suite source SHA or cleanup policy changed in repair19.
+
+Still pending: Root first inspects normal scrollbar operation in a short disposable
+diagnostic, then freezes source and runs a fresh contiguous long OS/native attempt;
+exactly one final all-suite regression on the derived roster; independent Opus
+review of all five conditions with raw-proof access; integration, current final
+verification and ledger. Windows same-distribution/device remains open with no
+Mac substitution. Local command outcomes are recorded in implementation.json.
