+## 2026-09-25 — separate mixed CLI discovery from editable ordinary loading
+
+Expose `arcadia check-mixed ROOT [--json]` through a closed read-only dispatch and
+opaque mixed source snapshot. Reuse the real parser and existing disk checks,
+but do not construct or expose an ordinary editable index for typed input.
+The [contract](analysis-mixed-cli-contract-20260925.md) specifies explicit
+identities, source8, report fields, original locations and exit behavior.
+
+Share one discovery Budget/ModelCounts across included files and reserve the
+file metadata before parsing. Retain producer counters conservatively after
+each temporary syntax unit drops. This is cumulative discovery reservation,
+not a claim about live allocations. Drop that phase before complete semantic
+validation under a fresh budget with the original caller policy. Clamp the
+source-byte ceiling before disk reads. Stop on the first located mixed parsing
+failure so a span-only budget latch cannot be attributed to a later sibling;
+retain final filesystem and pending-journal checks.

+whole independent OA/SA models, exact reports and bytes, cumulative limits,
+ordinary migrations/saves and finite stack controls. New public disk and CLI
+tests passed initially; two old CLI assertions still expected schema7. Correct
+only their exact migration/header expectations, retaining the immutable fixture,
+all40 identities and full-text/model/fixed-point checks. Alias the test process
+Command import to remove the observed warning. Preserve those original outcomes.
+
+Independent review also found the actual alarm include_str fixture missing
+from the inherited recorder's input recipe. Add that precise path before final
+gates (567 inputs); keep the six initial 566-input receipts and their omission
+caveat. Final source-bound checks pass 302 core,98 integrations,3 docs, strict
+core/CLI Clippy and5 direct CLI runs. Formatting remains the same inherited
+failure. Publication recovered without changing the existing release; mixed
+editing, application adoption and Linux qualification remain separate work.
