Health prop from ProjectBox via getProjectHealth(). ProjectBox starts/stops fs watcher per project CWD via $effect.
 - session_metrics SQLite table: per-project historical session data (project_id, session_id, timestamps, peak_tokens, turn_count, tool_call_count, cost_usd, model, status, error_message). 100-row retention per project. Tauri commands: session_metric_save, session_metrics_load. Persisted on agent completion via agent-dispatcher.

 - Agent tree (AgentTree.svelte) uses SVG with recursive layout. Tree data built by `agent-tree.ts` utility from agent messages.
 - ctx integration opens `~/.claude-context/context.db` as SQLITE_OPEN_READ_ONLY — never writes. CtxDb uses Option<Connection> for graceful absence if DB doesn't exist.
 - SSH sessions spawn TerminalPane with shell=/usr/bin/ssh and args array. No SSH library needed — PTY handles it natively.

 ### Added
-- **S-2 Session Anchors** — preserves important conversation turns through context compaction chains. Auto-anchors first 3 turns (6144 token budget) with observation masking on first compaction event. Manual pin button on AgentPane text messages.

Per-project 4-stop range slider in SettingsTab. `ProjectConfig.anchorBudgetScale` persisted in groups.json. ContextTab budget meter derives from project setting. agent-dispatcher resolves scale on auto-anchor
 - **Agent provider adapter pattern** — full implementation (3 phases complete): core abstraction layer (provider types/registry/capabilities, message adapter registry, 4 file renames), Settings UI (collapsible per-provider config panels, per-project provider dropdown, settings persistence), sidecar routing (provider-based runner selection, env var stripping for CLAUDE*/CODEX*/OLLAMA*). 5 new files, 4 renames, 20+ modified. 6 architecture decisions (PA-1–PA-6).

 ### Changed
+- Anchor observation masking no longer truncates assistant reasoning text (was 500 chars) — reasoning is preserved in full per research consensus (JetBrains NeurIPS 2025, SWE-agent, OpenDev ACC); only tool outputs are compacted (anchor-serializer.ts)
+- `getAnchorSettings()` now accepts optional `AnchorBudgetScale` parameter to resolve budget from per-project scale setting (anchors.svelte.ts)
+- ContextTab now derives anchor budget from `anchorBudgetScale` prop via `ANCHOR_BUDGET_SCALE_MAP` instead of hardcoded `DEFAULT_ANCHOR_SETTINGS` (ContextTab.svelte)
 - Renamed `sdk-messages.ts` → `claude-messages.ts`, `agent-runner.ts` → `claude-runner.ts`, `ClaudeSession.svelte` → `AgentSession.svelte` — provider-neutral naming for multi-provider support
 - `agent-dispatcher.ts` now uses `adaptMessage(provider, event)` from message-adapters.ts registry instead of directly calling `adaptSDKMessage` — enables per-provider message parsing
 - Rust `AgentQueryOptions` gained `provider` (String, defaults "claude") and `provider_config` (serde_json::Value) fields with serde defaults for backward compatibility

 - `tauri-plugin-log` dependency from Cargo.toml — redundant with telemetry::init() tracing-subscriber setup
 - Individual E2E spec files (smoke.test.ts, keyboard.test.ts, settings.test.ts, workspace.test.ts) — consolidated into bterminal.test.ts
 - Workspace teardown race: `switchGroup()` now awaits `waitForPendingPersistence()` before clearing agent state, preventing data loss when agents complete during group switch (agent-dispatcher.ts, workspace.svelte.ts)

+- [x] Added 4-stop range slider to SettingsTab per-project settings
+- [x] Updated ContextTab to derive budget from anchorBudgetScale prop
+- [x] Updated agent-dispatcher to look up project's budget scale
