- #17350: \[Bug\]: Holographic memory silently degrades to FTS5-only when numpy is missing — no warning, no error, no doctor detection
- PR #34109: fix(holographic): warn when numpy missing so HRR degradation is visible
- PR #39666: fix(memory): warn when numpy is missing in holographic memory (#17350)

These issues and PRs concern holographic memory silently falling back to FTS5-only mode when numpy is absent, with no warning or diagnostic signal. The work addresses adding visible warnings to surface this degraded state to users.

## TL;DR

- 6 member(s): 1 open issue(s), 1 closed issue(s), 2 open PR(s), 0 merged PR(s), 2 PR(s) closed without merging.
- No fix has been merged to main; one or more PRs were attempted (see below).
- **Recommended:** review the prior/competing PR(s) below. A fix was attempted but not merged; your case may extend or revive that work.

## Maintainer resolution verdict

- Internal-tracker verdict over this cluster's issue members: `unresolved`. This is distinct from the fix status above. Weigh it yourself.

## How this cluster was grouped

- Link evidence (`STRUCTURAL_PARTIAL`): some members are connected by structural evidence (shared changed files, or a closing/superseded reference); the rest are joined by an automated relevance judgement over their text.
- Members outside that structural core may belong to a different underlying problem.
- Pairwise link density `0.29`: the share of member pairs that carry a link, counting a structural link in full and a relevance-only link at 0.36. `1.00` means every pair is linked.
