Merge base is exact 13A checkpoint; merge retained both parents. +- Shared source carried: Python namespace/import/C3 resolution and future annotations, PHP trait/global-use resolution, Go receiver identities/multi-return, ASP.NET routes, test-file scope correction, graph follow-up guidance, and extraction/pipeline changes. `CBM_INDEX_FORMAT_VERSION` remains 4; semantic coverage version is 9. +- Conflicts: `src/cli/hook_augment.c` (merged neutral payload parser with follow-up guidance, adapted names to native `trace`/`snippet`/`search`); `src/pipeline/pipeline_internal.h` (retained both definition-property and route declarations). Upstream modifications to `src/mcp/mcp.c` and `tests/test_mcp.c` were removed to preserve CLI architecture. One MCP-backed follow-up test was folded into the adjacent native-operation-host hook test. No MCP server/transport was restored. +- Validation: `scripts/build-dev.sh` passed. `scripts/test.sh --suites 'extraction parallel pipeline php_lsp registry edge_types_probe doc_mentions_go doc_links_pdf'` passed 1,502 tests under ASan/UBSan after updating a stale LSP surface fixture from codec v2 to v3; `scripts/test.sh --smart --tests 'pipeline:pipeline_lsp_surface_decode_preserves_array_order_and_nulls'` passed 1/1; `scripts/test.sh --smart --tests 'cli:cli_hook_augment_context_tracks_search_json_shape'` passed 1/1. The first broad run exposed the stale fixture and an early-return arena leak; corrected fixture passes and cleans up normally. +- `python3 scripts/ci/check-github-actions-policy.py` passed (manual/reusable events only; Jenkins owns automatic CI). No Windows validation, push, PR, or Jenkins run is claimed for this checkpoint. +- Review/acceptance and full Jenkins remain pending. Graph CLI fallback: `codebase-memory-cli projects --json` failed with `secure CLI coordination could not be created (cache-resolve)`; structural claims above use exact Git/source fallback.

No Jenkins qualification or Windows verification is claimed for this candidate. Unauthenticated Jenkins API returned HTTP 403 and GitHub's combined status for the fork base had no contexts; PR discovery and result publication are unverified. +- Priority fixes #2207 and #2315/#2864 are being investigated in separate branches `fix/upstream-2207-lifetime-20261102` and `fix/upstream-adr-race-20261102`. Their first Agent Runs and lineage-preserving retries became orphaned and were terminated without completion. The #2207 patch is committed at `96e44e2a87492e4e2ac66ad5c39b6a889192f995` in [draft PR #31](https://github.com/ngallodev/codebase-memory-cli/pull/31). Linux `daemon_ipc` passed 57 tests under ASan/UBSan after commit; Jenkins and concurrent-interleaving review remain pending. The ADR branch remains unchanged. Do not assume their code is accepted or tested. +- Existing local `sync/upstream-remainder-20261102` contains provisional true merges through 13H (`84682e966b2df76d6eeb04655d5eabb7ee5833e7`) and an unresolved 13I merge with target `d1d8bbfa8fb52b0312dbbf1bf48b2787a7273a56`. Its Agent Run failed (`seal_failed`); preserve the unmerged worktree and inspect/resolve its conflicts only after reconciling its evidence. 13C–13H require independent review and qualification before advancing a dependent PR stack. +- PRs #28 and #29 were closed after confirming their exact heads were ancestors of main; #27 was already merged. The main checkout's unrelated untracked files were preserved. +- #2207 review: the two-file patch has the same stable patch ID as upstream merge `c80a2569995c44d7ad8522ea97e5944c4b5265be`. Its same-process fast paths avoid closing a second descriptor when a claim is already observed. A concurrent probe/acquire interleaving remains a review question: the registry check releases its mutex before the probe opens and closes the file, so a new claim could arise in between. Verify or eliminate that interleaving before treating the correction as complete. Do not infer test success from the interrupted worker builds. + +The canonical upstream audit remains `docs/UPSTREAM_308_CANDIDATE_AUDIT_20260912.md` (the filename is retained for stable links).
