Close Item 29: chainPass confirmed true via real CI (PR #421 merge)

[mixmansoundude]

Summary

Docs-only follow-up confirming CLAUDE.md Active Backlog Item 29 (second :dll_bundle_recover
pass after :hidden_import_recover, merged in PR #421) via real CI evidence, per the standing
"implement, then confirm before considering closed" policy already applied to Items 24 and 28.

self.layered_e2e.chain's chainPass reads true for the first time (PR #421 merge commit
dcfce1d, cache-lane run 31264219121,
~selftest_layered_e2e/~layered_e2e_bootstrap.log). The exact designed sequence fired for real,
in order, in one run:

[REPAIR][HIDDEN_IMPORT] Adding --hidden-import=numpy --collect-submodules=numpy; rebuilding EXE (iter 1/3).
[REPAIR][HIDDEN_IMPORT] Adding --hidden-import=pyproj --collect-submodules=pyproj; rebuilding EXE (iter 2/3).
[REPAIR][DLL_BUNDLE] Bundling native DLL dependency: proj_9.dll (found at ...\Library\bin\proj_9.dll); rebuilding EXE (iter 1/3).
[REPAIR][DLL_BUNDLE] Native-DLL bundling complete (1 DLL(s) added); EXE will be re-verified next.
[REPAIR][HIDDEN_IMPORT] Adding --hidden-import=colorama --collect-submodules=colorama; rebuilding EXE (iter 1/3).
[REPAIR][HIDDEN_IMPORT] EXE verified after hidden-import recovery.
[INFO] EXE smokerun: exited 0 (ok)
[STATUS] Run Status: SUCCESS (Exit Code: 0)

The pulled NDJSON row confirms mech1Pass/mech2Pass/mech3Pass/mech4Pass and the overall
pass (chainPass) all true -- the full uv-to-conda cascade, warnfix repair, hidden-import
recovery, and native-DLL bundling chain fired for real in one run, with three successive items
(24, 28, 29) each handing off to the next exactly as designed.

Also confirms the base HP_PYSPEC_WRITEBACK drop-to-unconstrained fix via the same row's
pinDropped:true/condaSelected:true fields (the range-preservation half,
HP_PYSPEC_ORIGINAL, remains unconfirmed -- this fixture's own pyproject has no constraint to
preserve).

Changes

• Moves Item 29 from CLAUDE.md's Active Backlog to docs/agent-closed-backlog.md (keeping its
  original number), appending the confirmation evidence to its existing entry.
• Updates now-stale "not yet confirmed"/"NOT YET CONFIRMED" language in
  docs/agent-interconnect.md, docs/agent-ndjson.md, and docs/agent-lessons-learned.md.

Test plan

• tools/run_sanity_sweep.sh -- all clean, 515 passed / 3 skipped (docs-only change).
• python tools/check_ndjson_registry.py --repo-root . -- clean, no registry mismatches.
• No run_setup.bat edit, so no delimiter/payload-sync concerns.

Timestamp: 2026-08-01T02:27:53.952Z
Learning: In the documentation files describing the removed UNC warning check in `run_setup.bat`, state only verified behavior: the check emitted `[WARN] UNC paths not supported` for an ordinary local path and was removed because the separate UNC-prefix guard already handles UNC detection. Do not assert the exact `findstr` or cmd.exe backslash-parsing mechanism, since it was not independently verified.
