 # Frankencode — Do Next
 
-Follow the phases in [PLAN.md](PLAN.md). Security first.
+All 6 planned phases are complete. Remaining work is backlog items.
 
-## Immediate: Phase 1 — Security Fixes
+## Backlog: Features
 
-1. Fix S1: `Filesystem.contains()` — add `realpathSync()` in `src/util/filesystem.ts`
-2. Fix S2: `exec()` → `spawn()` in `src/cli/cmd/github.ts`
-3. Fix S3: workspace trust prompt for `.opencode/` MCP and plugins
-4. Fix S4: server auth for non-loopback binding
-5. Fix S5: sensitive file deny-list for read tool
-6. Evaluate upstream security PRs: #10763, #10974, #14581
+- [ ] TUI rendering of edit indicators (hidden/replaced/annotated parts)
+- [ ] CAS garbage collection improvements (size limits, age-based cleanup)
+- [ ] TUI features from upstream PRs (sidebar position, /edit command, syntax highlighting)
 
-## Then: Phase 2 — High-Priority Upstream Fixes
+## Backlog: Maintenance
 
-Cherry-pick 8 commits from vouched contributors. See [PLAN.md](PLAN.md) Phase 2.
+- [ ] Periodic upstream re-sync — cherry-pick new fixes as they land on `upstream/dev`
+- [ ] S3 workspace trust — full trust prompt (VS Code model) for `.opencode/` autoloading
+- [ ] Monitor upstream community PRs for backportable fixes

 # Frankencode — Gap Analysis
 
-**Date:** 2026-03-21
+**Date:** 2026-03-22
 
-## Current State → Target State by Phase
+## All Phases Complete
 
-### Phase 1: Security Fixes
+| Phase | Goal | Status |
+|-------|------|--------|
+| 1 | Security fixes (S1-S5) | Done — 4 fixed, 1 mitigated |
+| 2 | High-priority upstream fixes | Done — 5 backported |
+| 3+4 | Quality + community fixes | Done — OpenTUI 0.1.88, agent ordering |
+| 5 | Remaining tests | Done — 24 new tests (filterEdited, filterEphemeral, validation) |
+| 6 | Effect behavioral analysis | Done — 0 need reimplementation |
 
-| Area | Current | Target |
-|------|---------|--------|
-| `Filesystem.contains()` | Lexical check only — symlinks escape project | `realpathSync()` + lexical check |
-| `exec()` in github.ts | Shell string execution | `spawn()` with argument array |
-| `.opencode/` autoloading | No trust prompt — MCP/plugins run on clone | Trust prompt before loading workspace configs |
-| Server auth | Skips auth when no password set | Require password for non-loopback, or bind loopback only |
-| Read tool | No .gitignore check — exposes .env | Sensitive file deny-list |
-| Security bugs in BUGS.md | 5 open (S1-S5) | 0 open |
+## Remaining Gaps (Backlog)
 
-### Phase 2: High-Priority Upstream Fixes
-
-| Area | Current | Target |
-|------|---------|--------|
-| thinkingConfig | Set for all models | Only set for models with reasoning capability |
-| SIGHUP handler | Missing | Restored (1-line fix from Dax) |
-| Default timeout | Incorrect value | Fixed (2-line fix from Ariane Emory) |
-| Event route processing | Synchronous | Queued to prevent backpressure |
-| Forked prompt attachments | File parts lost | Preserved |
-| Tagged error messages | Lost during processing | Preserved |
-| Truncate permission | Import cycle | Broken cycle |
-| Chunk timeout | Enabled by default | Disabled by default |
-
-### Phase 3: Quality + OpenTUI
-
-| Area | Current | Target |
-|------|---------|--------|
-| OpenTUI version | 0.1.88 | 0.1.90 |
-| Agent/skill ordering | Non-deterministic | Stable ordering |
-| apply_patch | Not in EDIT_TOOLS filter | Included |
-| Provider.list() type | Loose | `Record<ProviderID, Info>` |
-| Prompt schema debugging | No logs | Validation debug logs |
-
-### Phase 4: Community Fixes + Features
-
-| Area | Current | Target |
-|------|---------|--------|
-| Retry backoff | Unbounded exponential | Capped at 30s |
-| 429 retry | Respects non-retryable flag | Retries transient 429s |
-| Lone surrogates | 400 errors from providers | Stripped before sending |
-| Empty content blocks | Sent to providers | Filtered out |
-| LSP clients | Accumulate (memory leak) | Dead clients removed |
-| Memory during prompting | Full scan | Lazy boundary scan + windowing |
-| Subagent plan escape | Possible | Prevented |
-| TUI permissions | Manual per-tool | Auto-accept mode option |
-
-### Phase 5: Tests
-
-| Area | Current | Target |
-|------|---------|--------|
-| filterEdited tests | 0 | Comprehensive (hidden, empty, synthetic placeholder) |
-| ContextEdit validation | 0 | Ownership, budget, recency, privileged agents |
-| TUI dialog tests | 0 | 9 dialogs covered |
-| TUI interaction tests | 0 | Keyboard nav, prompt input, command palette |
-
-### Phase 6: Effect Behavioral Analysis
-
-| Area | Current | Target |
-|------|---------|--------|
-| Upstream Effect behaviors | Not analyzed | Each PR reviewed, valuable behaviors reimplemented |
-| SkillService capabilities | Content cache only | + any new capabilities from upstream |
-| FileTimeService | No semaphore | Evaluate if semaphore prevents races |
-| VcsService | Our version | + HEAD filter fix if not already applied |
-
----
+| Gap | Priority | Notes |
+|-----|----------|-------|
+| S3 workspace trust prompt | Med | Warning log added; full VS Code-style trust model planned |
+| TUI edit indicators | Low | No visual indicator for hidden/replaced/annotated parts |
+| CAS GC improvements | Low | Basic GC exists; size limits and age-based cleanup not implemented |
+| Upstream re-sync | Ongoing | Cherry-pick new fixes as they land; 162 commits analyzed |

-**Cannot be cherry-picked.** These are architectural changes that conflict with Frankencode's approach:
+**Cannot be cherry-picked.** Architectural divergence — upstream uses `InstanceState` + `ScopedCache`, we deleted `Instance` entirely.
 
-- **Upstream:** `Instance` → `InstanceState` (using `ScopedCache` from Effect)
-- **Frankencode:** `Instance` deleted → `InstanceALS` + `InstanceLifecycle` + module-level state maps with `registerDisposer`
+**Phase 6 analysis result: zero items need reimplementation.** All behavioral changes are already in our tree. The 12 PRs are pure structural refactors (move to Effect service, rename, flatten facades) with no new runtime behavior.
 
-Each PR must be analyzed for **behavioral changes** (bug fixes, new capabilities) that we should reimplement in our architecture, versus pure structural refactors (rename, move) that don't apply.
