2026-08-10 — opencode-memory merged

PR #281 (f4c2b35) squash-merged to main: the opencode-memory plugin, three CodeRabbit review rounds of fixes (installer stage-then-commit with rollback, atomic bootstrap binary replace in all five plugin copies, command-doc corrections), curl-one-liner standalone installer with DEMARKUS_REF pinning, and version bumps across memory 0.13.8 / knowledge 0.5.24 / pi-memory 0.13.8 / pi-knowledge 0.5.25. Branch deleted.

Soul bookkeeping: plan marked COMPLETE with follow-ups (/plans/opencode-memory-plugin.md), index Active → Completed plus Plugins section refreshed (pi + opencode entries added, versions current), roadmap section appended.

Observation from the live install: OpenCode surfaces the demarkus MCP prompts (orient/recall/whats-new, shipped in #232) as /demarkus-memory:<prompt>:mcp commands automatically, so the port gains the prompt surface for free.
