17 — DOC: Duplicate US-020 issue dedup

What to build

Two files share the US-020 number with different slugs:

• docs/issues/20-memory-budget-shard-slots-and-dropout-relocation.md (ready-for-agent)
• docs/issues/20-tracker-node-hardening.md (done)

Resolve numbering collision without losing history.

Acceptance criteria

• Document canonical mapping in this issue's Comments or a short docs/issues/README.md note
• Renumber or prefix disambiguation (e.g. keep done item as US-020a, renumber memory-budget to next slot) — human approval before git mv
• Update any prd.json / cross-links that reference US-020 ambiguously
• No production code changes

Blocked by

Human approval for renumbering. An agent may prepare the mapping note, but must not run git mv or rewrite cross-links until the canonical number is approved.
