Base commit: c55e9c7182
Owner: codex
Status: Ready for Integration

Merge the committed teacher reference-isolation fix a931803 (code 36202e0) into local main while preserving the exact tested implementation.

User authorizes main merge and conflict resolution. No remote push, live-app refresh, cloud publication, paid calls or subagents. Preserve source records, history/drafts, and foreign task worktrees; canonical memory is read-only.

Merged a931803 (reference-isolation code 36202e0) without conflicts in merge 2849e67 and fast-forwarded local main from c55e9c7. Original source commits, README and regression tests are included; no product changes during merge.

Exact full source tree equivalence verified against a931803, excluding only this task record. Source evidence: 125 unit tests, one Electron selection/reference test, typecheck, production compile, scoped lint; full lint has 0 errors and 8 existing warnings. No code change warrants duplicate execution.
Whitespace/unmerged-index and clean-main checks passed; main ancestry includes a931803. Official drift checker flags the source task record imported by the merge as FOREIGN_DOC relative to main base. Verified source/current Git blob exactly 5e4b9b292a4120f7222828b5dff9b5a5b4e259ba; the source record is unchanged, with no foreign or canonical edits. Preserved original history and reported the checker limitation rather than adopting or rewriting its ownership.

Main merge complete; remote push was not requested. Trial already contains the fix from the preceding turn and is unchanged. Worktree cleanup is optional and awaiting user choice.

Existing source proposal on operation-only, scoped, one-time quote handoff remains for a future canonical integration. No new product decision.

Task ID: 20260930-teacher-reference-merge-b731e95a; Feature mode; owned branch/worktree and c55e9c7 base match official start/status. App worktree tool unavailable in parent non-Git workspace, official isolation fallback succeeded.
Read AGENTS, entry/memory index, own task, positioning, current integrated state, decision index/teacher ADR, system overview/data flow, domain/success criteria, evidence and commitments, all peer task Scope/Intent/Promotion sections. Reused unchanged source-task verification context.
Product: cloud-defined teachers help children with their current projects. Account/project/teacher drafts and histories stay separate; explicit operation references retain source identity. This merges the already tested source without changing that contract.
Peer tasks: preview-toolbar-tabs modifies nearby CodingChatPanel layout independently; alice-tool-leak is read-only diagnosis. Older release/help-label scopes and undefined child-language scope have no dependency on this exact committed merge. No peer uncommitted code adopted. Canonical integration remains owned by a foreign task; no canonical promotion here.
Latest fetched main/origin/main: c55e9c7, clean and identical. Source a931803 descends directly from it. No semantic conflict; obsolete canonical portions are not reintroduced. Source tests/build/typecheck/Electron evidence available. Files: two product panels, README, unit/Electron regressions and source/merge task records.
Gate: Passed.

Merge source with its original commits in this owned candidate; inspect tree equivalence and unresolved entries.
Reuse exact-source successful regression/type/lint/build/Electron evidence if product/test tree is unchanged; rerun only if conflict resolution changes code.
Record result, fast-forward clean unchanged local main to the reviewed candidate, verify ancestry and diff. Ask optional cleanup after completion; do not push.
