+## [0.12.0] — 2026-04-27
+
+Minor release. Adds the opt-in `tldraw` seed skill for live canvas diagrams
+and a skill-local snapshot store. The feature stays beta and off by default.
+
+### Added
+- **`tldraw` seed skill — live canvas diagrams.** Adds
+  `.agent/skills/tldraw/SKILL.md` with MCP tool guidance, shape constraints,
+  and a self-rewrite hook for diagram, sketch, wireframe, flowchart,
+  whiteboard, and architecture visualization prompts.
+- **Skill-local snapshot store.** Adds `.agent/skills/tldraw/store.py` with
+  `snapshot`, `list`, `load`, and `archive` CLI/API support. Runtime output is
+  local and gitignored under `.agent/skills/tldraw/`: `snapshots.jsonl`,
+  `snapshots/`, and `INDEX.md`.
+- **Opt-in feature flag.** Onboarding now writes a `tldraw` beta feature flag,
+  default off. The skill loader skips flagged skills unless
+  `.agent/memory/.features.json` explicitly enables them.
+- **Manual MCP config source.** Adds `adapters/_shared/tldraw-mcp.json` as the
+  canonical tldraw MCP config block users can merge into Claude Code,
+  Cursor, or Antigravity after enabling the feature.
+
+### Changed
+- Seed skill count is now nine: `skillforge`, `memory-manager`, `git-proxy`,
+  `debug-investigator`, `deploy-checklist`, `design-md`, `data-layer`,
+  `data-flywheel`, and `tldraw`.
+- tldraw persistence is intentionally skill-local storage, not a fifth memory
+  layer: it has no dream-cycle, clustering, recall, or semantic-memory
+  lifecycle.
+- Default adapter installs no longer wire beta tldraw MCP config
+  automatically.
+
+### Fixed
+- Updated the tldraw validation suite to target
+  `.agent/skills/tldraw/store.py` instead of the removed
+  `.agent/memory/visual/visual_memory.py`.
+- `store.py` renders `INDEX.md` while holding the JSONL lock so concurrent
+  snapshots cannot leave the index stale.
+- Added coverage for feature-gated skill loading, no default MCP install, path
+  traversal rejection, malformed JSONL recovery, same-second snapshot ids, and
+  concurrent snapshots.
+
+### Migration
+No migration required. Existing installs keep tldraw disabled until users opt
+in through onboarding reconfiguration or `.agent/memory/.features.json`.
+
+### Credits
+- PR #11 by @Siddharth11Roy, with review fixes and release prep by Codex.

-### New in v0.11.2 — natural dashboard access
-
-Patch release. The data-layer skill is now the injected dashboard surface: a
-model can decide to show the dashboard when a user asks naturally, without
-making people remember exporter flags.
-
-- **Injected dashboard skill.** The `data-layer` skill now triggers on plain
-  phrases like "show me the dashboard" and "what did my agents do", then shows
-  the terminal dashboard directly in the coding tool.
-- **Natural-language exporter.** Users and agents can run
-  `python3 .agent/tools/data_layer_export.py show me last 7 days by hour`;
-  the exporter maps that to the right window and bucket while keeping explicit
-  flags available for scripts.
-- **Onboarding-style terminal view.** The dashboard now borrows the same
-  rail, marker, and summary style as the onboarding flow, and still saves a
-  plain `dashboard.tui.txt` beside `dashboard.html`, CSV, JSON, and
-  `daily-report.md`.
+### New in v0.12.0 — tldraw visual canvas
+
+Minor release. Adds an opt-in `tldraw` seed skill for live canvas diagrams and
+a skill-local snapshot store. It is beta and off by default.
+
+- **`tldraw` seed skill.** Draw, diagram, sketch, wireframe, flowchart, and
+  whiteboard on a live canvas at `http://localhost:3030` through an MCP server.
+- **Skill-local snapshots.** Save worthwhile canvases with
+  `.agent/skills/tldraw/store.py snapshot`; list, load, and archive them later
+  without treating them as a fifth memory layer.
+- **Opt-in beta.** Onboarding writes `tldraw.enabled: false` by default. After
+  enabling it, users manually merge `adapters/_shared/tldraw-mcp.json` into
+  their harness MCP config.
