Answer 1

I diagnosed the bug against the actual repo (coding-hermes/auger @ 76f9e43), implemented the fix, and verified it offline. The full solution is written to ~/solution.md.

Summary

Root cause (two compounding defects in auger.py):

  1. ns_dir() hardcoded ~/duckbrain/namespaces/<ns>, while the substrate resolves its declaration tree from DUCKBRAIN_NAMESPACES_PATH. init wrote 14 .table.json files into the wrong tree (polluting ~) and the API never saw them.
  2. cmd_init computed the tally (declared: 0/14) and warned, but return 0 ignored it — a wrong-tree install exited green, and the next verb 404'd with Table 'project' not found.

Fix: resolve the root the way the substrate does — --namespaces-path → $DUCKBRAIN_NAMESPACES_PATH → $DUCKBRAIN_DATA_DIR/namespaces → ~/duckbrain/namespaces — and make a 0/N tally raise SystemExit (rc 1) naming both directories.

Verification (all run here): - Offline harness (real cmd_init, real resolver, real writes; only urlopen faked): resolution precedence PASS, init rc≠0 on 0/14 PASS, init rc=0 on 14/14 PASS, --namespaces-path overrides env PASS. - Existing suite: pytest -q → 45 passed, 138 skipped (live tests skip without a substrate).

The markdown contains the full root-cause analysis, the exact patch (§2.1–2.3), the zero-code symlink workaround (§2.5), the runnable offline verifier, and the live reproduction commands. The core patch:

            f"the right place, restart the API so it re-reads them"
        )

main() gains the global --namespaces-path DIR flag and calls set_namespaces_root(a.namespaces_path) before dispatch. See ~/solution.md for the complete write-up and copy-pasteable verification.

Answer 2

I diagnosed the bug against the actual repo (coding-hermes/auger @ 76f9e43), implemented the fix, and verified it offline. The full solution is written to ~/solution.md.

Summary

Root cause (two compounding defects in auger.py):

  1. ns_dir() hardcoded ~/duckbrain/namespaces/<ns>, while the substrate resolves its declaration tree from DUCKBRAIN_NAMESPACES_PATH. init wrote 14 .table.json files into the wrong tree (polluting ~) and the API never saw them.
  2. cmd_init computed the tally (declared: 0/14) and warned, but return 0 ignored it — a wrong-tree install exited green, and the next verb 404'd with Table 'project' not found.

Fix: resolve the root the way the substrate does — --namespaces-path → $DUCKBRAIN_NAMESPACES_PATH → $DUCKBRAIN_DATA_DIR/namespaces → ~/duckbrain/namespaces — and make a 0/N tally raise SystemExit (rc 1) naming both directories.

Verification (all run here): - Offline harness (real cmd_init, real resolver, real writes; only urlopen faked): resolution precedence PASS, init rc≠0 on 0/14 PASS, init rc=0 on 14/14 PASS, --namespaces-path overrides env PASS. - Existing suite: pytest -q → 45 passed, 138 skipped (live tests skip without a substrate).
