+# Task: Integrate teacher read completion repair
+
+## Identity
+
+- Task ID: 20260926-merge-teacher-read-ml-616605aa
+- Mode: Integration
+- Branch: main
+- Worktree: D:\Datas\OthersProjects\makelore
+- Base commit: 287dcd303d3c99665e95eca3345c4ee3270a855f
+- Owner: codex
+- Status: Ready for Integration
+
+## Scope
+
+- Merge reviewed source 60c20f996e8428d4dfbd5efb92792d3900722af5 into local main and promote the confirmed teacher read-completion contract. No product changes beyond the reviewed source.
+
+## Intent And Constraints
+
+- Concurrent and Planning Gates Passed. Official check/start/status establish exclusive integration ownership with Identity above. Loaded entry, own/source records, current teacher positioning/decisions/architecture/domain and evidence/reflection/commitments; inspected peer records and reused unchanged previous context. Historical template scopes/positioning remain unknown with no concrete dependency on this merge.
+- User explicitly approved handing off the previous avatar integration registration through release --force and preserving the known foreign documents through --adopt-existing. All five documents across both repositories stay unchanged and outside commits. Source records stay read-only; no new subagents, push, deployment, installation or deletion.
+- Plan: fast-forward the exact reviewed source, verify ancestry and equality with the reviewed product/test tree, promote runtime facts to canonical memory, pass documentation and whitespace gates, then commit and complete. Reuse source test/review evidence when the product tree is identical.
+
+## Outcome
+
+- Fast-forwarded local main to reviewed source 60c20f996e8428d4dfbd5efb92792d3900722af5 without conflicts. Product, tests, public documentation and imported source records match the reviewed source.
+- Promoted the six-batch completion and distinct client error semantics into system-overview and current-state. No conflicting accepted product or billing decision; original read quota/context/version/deadline and student funding remain.
+
+## Verification
+
+- Source independent review 20260926-teacher-read-review-b7d3e91a: PASS without material findings; independent reruns covered one six-batch HTTP/PG/Redis/worker/SDK case and six focused client cases.
+- Reused source evidence for identical product/test bytes: Makelore 130 related unit tests plus three corrected malformed-batch cases, typecheck and Vite all-target build passed; existing build warnings remain disclosed.
+- Fast-forward ancestry, exact reviewed product-tree comparison, imported source-record equality, whitespace and official task-aware documentation gates passed. The drift check also confirms all adopted foreign documents retain their original states.
+
+## Follow-ups
+
+- Source worktree retained awaiting the separate post-merge cleanup confirmation. Branch and committed result remain preserved; cleanup does not block the completed local merge.
+- Production supplier requests, live billing and installed-client acceptance remain unverified. Deploy the matching Yuxi worker and updated client before acceptance; existing failures are not automatically replayed.
+
+## Promotion Candidates
+
+- Accepted source runtime proposal applied to system-overview/current-state. No new product direction or semantic conflict; no source record modified.
