docs: update meta files for provider adapter implementation

 - [ ] **Multi-machine TLS/certificate pinning** -- TLS support for bterminal-relay + certificate pinning in RemoteManager.
 - [ ] **Agent Teams real-world testing** -- Env var whitelist fix done. 3 test sessions ran ($1.10, $0.69, $1.70) but model didn't spawn subagents — needs complex multi-part prompts to trigger delegation. Test with CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1.
 - [ ] **Configurable stall threshold** -- health.yaml per-project config for stall threshold (currently hardcoded 15 min). Adaptive suggestions after 50 sessions from session_metrics data.
-- [ ] **Agent provider adapter pattern** -- Abstract model interface (ProviderConfig, ProviderCapabilities) for multi-model support (Claude, Codex, Ollama). Rename agent-runner.mjs → claude-runner.mjs, capability gates in UI. **Planning complete** (docs/provider-adapter/task_plan.md): 3-phase plan, 6 architecture decisions (PA-1–PA-6), 24 tasks. Phase 1 (core abstraction) ready to implement.
+- [ ] **Add Codex/Ollama provider runners** -- Provider adapter pattern implemented (all 3 phases). Need to create codex-runner.ts and ollama-runner.ts sidecar runners + corresponding message adapters (codex-messages.ts, ollama-messages.ts) + register providers in App.svelte.
 - [ ] **S-2 — session anchors** -- Preserve first 5 turns / 2K tokens verbatim through checkpoint chains. Pin additional turns via AST conversation tree action.
 - [ ] **Worktree isolation per project (S-1 Phase 3)** -- Three parts: (1) **UI toggle**: useWorktrees checkbox in SettingsTab per-project settings, persisted in groups.json ProjectConfig. (2) **Spawn with --worktree**: when useWorktrees=true, pass `--worktree <session-slug>` flag to Claude Code CLI via sidecar AgentQueryOptions. Sidecar creates worktree at `<cwd>/.claude/worktrees/<name>/`, agent CWD is set there. (3) **Worktree detection improvement**: current extractWorktreePath checks tool_call params, but agents don't signal worktrees in tool calls — the real signal is CWD-based (path contains `.claude/worktrees/`) or from sidecar notification events (`worktreePath`/`worktreeBranch` fields, Claude Code v2.1.72+). Update agent-dispatcher to parse init event CWD or notification fields. For Codex/Cursor agents: detect `$CODEX_HOME/worktrees/` or `~/.cursor/worktrees/` CWD patterns. Conflict suppression already works once worktree is registered via setSessionWorktree().
 
 ## Completed
 
+- [x] **Agent provider adapter pattern** -- Multi-provider support (Claude, Codex, Ollama) via 3-phase adapter pattern. Core abstraction (provider types/registry/capabilities, message adapter registry, file renames), Settings UI (collapsible provider panels, per-project dropdown), Sidecar routing (provider-based runner selection, env var stripping). 5 new files, 4 renames, 20+ modified. 202 vitest + 42 cargo tests. | Done: 2026-03-11
 - [x] **Files tab PDF viewer + CSV table** -- PdfViewer.svelte (pdfjs-dist 5.5.207, canvas multi-page, zoom 0.5x–3x, HiDPI). CsvTable.svelte (RFC 4180 parser, delimiter auto-detect, sortable columns, sticky header). FilesTab routing: Binary+pdf→PdfViewer, Text+csv→CsvTable. | Done: 2026-03-11
 - [x] **Filesystem Write Detection (S-1 Phase 2)** -- inotify-based file change detection via notify crate (fs_watcher.rs). Timing heuristic (2s grace) for PID attribution — suppresses agent's own writes, surfaces external edits. EXTERNAL_SESSION_ID sentinel, recordExternalWrite(), externalConflictCount. Orange "ext write" badge + red "agent conflict" badge in ProjectHeader. ProjectBox $effect starts/stops per-project. Inotify watch limit sensing: reads /proc/sys max_user_watches, counts watched dirs, warns at >75% usage with fix command. 202/202 vitest + 42/42 cargo tests. | Done: 2026-03-11
 - [x] **Conflict Detection Enhancements (S-1 Phase 1.5)** -- Bash write detection (>, >>, sed -i, tee, cp, mv). Acknowledge/dismiss conflicts (clickable badge). Worktree-aware conflict suppression. useWorktrees ProjectConfig field. 194/194 tests. | Done: 2026-03-11

 - [x] **CodeMirror 6 editor** -- Replaced shiki viewer in FilesTab with CodeMirror 6. CodeEditor.svelte wrapper: 15 lazy-loaded language modes, Catppuccin theme, auto-close brackets, bracket matching, code folding, Ctrl+S save, dirty tracking, save-on-blur setting. write_file_content Rust command. | Done: 2026-03-10

 - [x] **Tab system overhaul** -- Renamed Claude→Model, Files→Docs. Added Files (VSCode-style tree+viewer), SSH (CRUD+launch), Memory (pluggable adapter) tabs. PERSISTED-EAGER/LAZY mount strategies. Rust list_directory_children + read_file_content commands. | Done: 2026-03-10
-- [x] **AgentPane collapsibles + aspect ratio** -- Text messages collapsible (open by default), cost summary collapsed by default. Project max aspect ratio setting (0.3–3.0, default 1.0) with CSS var + SettingsTab stepper. No-implicit-push rule 52. Desktop StartupWMClass. | Done: 2026-03-09
-- [x] **AgentPane + MarkdownPane UI redesign** -- AgentPane: sans-serif font, tool call/result pairing via $derived.by, hook message collapsing, context meter, muted colors via color-mix(), responsive margins via container queries. MarkdownPane: container query wrapper, shared responsive padding variable. Tribunal-elected design (S-3-R4, 88% confidence). 139/139 tests pass. | Done: 2026-03-09
