 # Project Milestones: Agent Memory
 
+## v2.7 Multi-Runtime Portability (Shipped: 2026-03-22)
+
+**Delivered:** Rust-based multi-runtime installer that converts canonical Claude plugin source into runtime-specific installations for 6 targets, replacing 5 manually-maintained adapter directories with a single conversion pipeline.
+
+**Phases completed:** 45-50 (6 phases, 11 plans)
+
+**Key accomplishments:**
+
+- `memory-installer` crate with `RuntimeConverter` trait and 6 runtime converters (Claude, Gemini, Codex, Copilot, Skills, OpenCode stub)
+- Plugin parser with 2-level discovery (installer-sources.json → marketplace.json) and gray_matter frontmatter extraction
+- Centralized tool mapping tables: 11 Claude tool names mapped across 6 runtimes with compile-time exhaustive match expressions
+- format!-based YAML/TOML emitters with proper quoting, block scalars, and path rewriting helpers
+- 7 E2E integration tests proving full convert-and-write pipeline for all runtimes
+- 3 old adapter directories archived with README stubs (51 files, 12K+ lines removed)
+
+**Known Gaps:**
+
+- OC-01–06: OpenCode converter is a stub (deferred — OpenCode runtime format still evolving)
+
+**Stats:**
+
+- ~56,400 total LOC Rust across 15 crates
+- 3,700 LOC in memory-installer crate
+- 111 cargo tests (104 unit + 7 integration)
+- Timeline: 2026-03-17 → 2026-03-22 (5 days)

 ## v2.5 Semantic Dedup & Retrieval Quality (Shipped: 2026-03-10)
 
 **Delivered:** Ingest-time semantic dedup via vector similarity gate with configurable threshold, query-time stale filtering with time-decay and supersession detection, and 10 E2E tests proving the complete pipeline.

+**Previous version:** v2.6 (Shipped 2026-03-16) — BM25 hybrid wiring, salience/usage decay, lifecycle automation, observability RPCs, episodic memory
 
-**Goal:** Complete hybrid search, add ranking intelligence, automate index lifecycle, expose operational metrics, and enable the system to learn from past task outcomes.
-
-**Target features:**
-- Complete BM25 hybrid search wiring (currently hardcoded `false`)
-- Salience scoring at write time + usage-based decay in retrieval ranking
-- Automated vector pruning and BM25 lifecycle policies via scheduler
-- Admin observability RPCs for dedup/ranking metrics
-- Episodic memory — record task outcomes, search similar past episodes, value-based retention
-
-**Previous version:** v2.5 (Shipped 2026-03-10) — semantic dedup, stale filtering, 5-CLI E2E test harness
