+## Echo semantic presentation source checkpoint
+
+The optional extension 1.4 acknowledgmentLabel and manualEntryEnabled hints are published on feature/echo-scanner-presentation (draft PR9). Existing defaults remain Saved scan/manual enabled; Echo uses Print queued/manual disabled. Strict compilation, 167 JVM cases, lint zero errors/warnings and debug assembly pass. Hardware, lifecycle and receipt predicates are unchanged. The server companion passes 69 consumer cases plus two contract cases; the optional Echo module passes 15 strict QQQ/H2 tests.
+
+The normal TC22 remains the separately installed 625a275 build (APK AF13778A…3E9216), preserving sign-in/data. Its About screen was opened and Query artwork, both public links and licenses verified through filtered accessibility data. New Echo-native UI/actual owner adapters/physical printing remain unqualified; printing and document/scripting owners have acknowledged their implementation lanes. The running normal server remains API1.9/mobile1.1. Production signing/distribution stays the owner's final step.

 ## November 1 standards fixes and About update
 
 Applied the scoped standards review: copyright/SPDX, explicit imports, declaration headers, native official/three-space formatter profile, mechanical CI source gate and Kotlin warnings-as-errors. Strict compilation and163 JVM tests pass; all46 disposable sample native tests pass on TC22, and production QA instrumentation compiles. The native suite uses fixture providers; actual Android external-browser/provider acceptance remains separate. The existing formatter reports one unstable Gradle script and full formatter CI runner provisioning remains explicit in the review.

 # TODO
 
+- [x] Add metadata-driven Echo acknowledgment/manual-entry hints with old defaults; 167 JVM tests, strict compilation, lint zero errors/warnings and debug build pass.
+- [ ] Qualify native Echo setup/scan/print-acceptance/leave with the actual owner adapters and independently decoded physical output; source tests are not physical printing evidence.
+- [x] Verify Query artwork, Dogfooding/Query links and licenses on the normal TC22 About screen using filtered accessibility data.
+
 - [x] Apply scoped copyright/import/header/formatter corrections, mechanical CI gate and Kotlin warnings-as-errors;163JVM plus46TC22 sample native cases pass. See [review](CODING-STANDARDS-REVIEW-2026-11-01.md) for the remaining formatter CI limitation.
 - [x] Add Query artwork, app version, Dogfooding/Query links and license access under Settings → About QQQ Mobile.
 - [x] Qualify real Authentik desktop nonce rejection and retained-browser A → company logout → fresh B; actual Android callback acceptance remains separate.

 ## Echo scanner presentation hints
 
-Mobile-scanners1.4 adds optional SCANNER acknowledgmentLabel and manualEntryEnabled. Existing servers retain Saved scan and manual entry. Echo supplies Print queued and false, hiding manual controls because typed text has no decoder-provided symbology. Explicitly malformed labels or nonboolean flags disable the control. These presentation hints never change the matching event/scanSaved/scanId acknowledgment rules, and queue acceptance does not mean physical output completed. No application or process name selects this behavior.
