-1. Inspect the current merge state:
-   - `git status --short`
-   - `git diff --name-only --diff-filter=U`
-   - `upstream-merge-report-<version>.md` when present
-   - `.worktrees/opencode-merge/auto-merge` for the automated merge snapshot when present
-2. Before editing, write a concise plan in the chat:
-   - file-by-file strategy
-   - expected resolution kind: `hybrid`, `take-ours`, `take-theirs`, `regenerated`, `removed`, `renamed`, or `other`
-   - risk level: `low`, `medium`, or `high`
-   - verification commands you expect to run
-3. Ask the user to approve the plan before applying any manual conflict
-   resolution. Do not resolve a file until the user has approved that file's
-   strategy.
-4. Resolve each conflict carefully, one file at a time.
+### 1. Inspect the current merge state
 
-   **Reference worktrees when present:**
-   - `.worktrees/opencode-merge/opencode` is the pristine upstream opencode tree
-   - `.worktrees/opencode-merge/kilo-main` is the Kilo base snapshot
-   - `.worktrees/opencode-merge/auto-merge` is the automated merge snapshot and the original conflict reference
+- `git status --short`
+- `git diff --name-only --diff-filter=U`
+- `upstream-merge-report-<version>.md` when present
+- `.worktrees/opencode-merge/auto-merge` for the automated merge snapshot when present
 
-   **Inspect conflicts (optional):**
-   - `script/upstream/find-conflict-markers.sh <file>` on the working tree
-   - `script/upstream/find-conflict-markers.sh .worktrees/opencode-merge/auto-merge/<file>` on the auto-merge snapshot
+### 2. Read every conflicted file end-to-end before planning
 
-   **Apply the resolution rules:**
-   - prefer upstream code and architecture whenever compatible with Kilo behavior
-   - preserve Kilo-specific behavior marked with `kilocode_change`
-   - keep `kilocode_change` markers around Kilo-specific changes in shared opencode files
-   - keep Kilo-specific text, code, and marker comments the same as the auto-merge conflict snapshot unless a refactor is required
-   - if Kilo-specific code must be refactored to fit new upstream architecture, explain the refactor in the final summary
-   - if upstream moved the relevant logic to another file, port the Kilo behavior there and list both paths in the final summary
-   - if upstream deleted a file, analyze whether the Kilo behavior should be ported elsewhere or removed rather than restoring the deleted file
-   - if tests fail only because upstream intentionally removed behavior, remove or update the obsolete tests rather than adding the old file back
-   - do not modify unrelated files
-5. After each file is resolved, verify the decision before moving on:
-   - inspect the resolved file and confirm it has no conflict markers
-   - compare against the opencode, kilo-main, and auto-merge references when present
-   - run the smallest relevant check for that file when practical
-   - summarize the exact resolution, tradeoff, and verification result in chat
-   - ask the user to approve the resolved file before staging it or resolving the next file
-6. Run the appropriate checks:
-   - stage resolved files with `git add -A` so git no longer reports unmerged paths
-   - if `packages/opencode/` shared files changed, run `bun run script/check-opencode-annotations.ts`
-   - run targeted typechecks/tests when practical for touched packages
-   - run `bun run typecheck` from the repo root before declaring the merge ready
-7. Finish with:
-   - files resolved
-   - resolution choices and rationale
-   - checks run and results
-   - any remaining high-risk areas for reviewer attention
+Use `script/upstream/find-conflict-markers.sh <file>` to jump to each region,
+then read enough surrounding lines to understand the code — not just the
+conflict hunk. Specifically check:
 
-Every manual merge decision requires explicit user approval before applying and
-again after verification. Be especially cautious when a decision is destructive,
-changes auth, billing, data deletion, public API compatibility, config schema
-behavior, migrations, provider routing, or security posture.
+- is this a plain 3-way on a single expression, or a structural refactor?
+- does upstream rename/move something that invalidates a HEAD-only declaration?
+- does a `kilocode_change` marker in HEAD encode a bug fix, a feature, or a
+  defensive check?
+- is the conflicted block referenced by *non-conflicted* code elsewhere in the
+  same file (imports, signatures, call sites) that will break if we drop it?
 
-Common pitfalls to watch for:
-- auto-merged code can reference declarations that still live inside conflict blocks
-- related sibling files can need edits even when they are not listed as unmerged
-- `renamed` should be used only when behavior moves to a different file
-- function signatures can drift across conflict boundaries
-- full repo typecheck is the catch-all for non-conflicted call-site breakage
+When HEAD includes a non-obvious Kilo-specific wrapper (e.g. a helper in
+`packages/opencode/src/kilocode/`), find out why it exists before deciding to
+keep or bypass it:
+
+```bash
+git log --all --oneline -S "<symbol>" -- packages/opencode/src/kilocode/
+git log --all --oneline -- <kilo-file>
+```
+
+Look at the commit message and any PR reference. "We wrote our own because of
+PR #NNNN" is a real constraint; "we wrote our own because of a typo" is not.
+
+### 3. Write a plan in chat and get approval
+
+For every conflicted file (and any adjacent file the resolution forces you to
+touch — see §6) include:
+
+- expected resolution kind: `hybrid`, `take-ours`, `take-theirs`, `regenerated`,
+  `removed`, `renamed`, or `other`
+- risk level: `low`, `medium`, or `high`
+- one-sentence rationale (what Kilo behaviour is preserved, what upstream
+  feature is adopted, what is dropped)
+- verification commands you expect to run (targeted tests, typecheck)
+
+Group files by risk level. Ask the user which batch to start with. You can
+resolve an entire `low` batch in one pass if the user approves the batch, but
+resolve `medium` and `high` files one at a time.
+
+**Do not resolve a file until the user has approved that file's (or batch's)
+strategy.**
+
+### 4. Before every edit, explain reasoning before showing the diff
+
+The user needs to review intent, not just the raw change. For each file, in
+order:
+
+1. Show the conflict's surrounding context (10–30 lines around each conflict
+   region, in chat).
+2. Explain what each of the three sides (HEAD, merge-base, upstream) is doing.
+3. State which Kilo behaviour must survive and why (reference PR numbers /
+   `kilocode_change` comments when possible).
+4. State the resolution and why it is better than the alternatives.
+5. Then apply the edit. The tool will display the diff — the user only has to
+   verify the diff matches the reasoning.
+
+Do not lead with the diff. A diff without reasoning forces the user to
+reverse-engineer the decision.
+
+### 5. Apply resolution rules
+
+Reference worktrees when present:
+
+- `.worktrees/opencode-merge/opencode` — pristine upstream tree
+- `.worktrees/opencode-merge/kilo-main` — Kilo base snapshot
+- `.worktrees/opencode-merge/auto-merge` — automated merge snapshot (original
+  conflict reference)
+
+Apply in order:
+
+- prefer upstream code and architecture whenever compatible with Kilo behaviour
+- preserve Kilo-specific behaviour marked with `kilocode_change`
+- keep `kilocode_change` markers around Kilo-specific code in shared opencode
+  files
+- when upstream refactors a region that HEAD had annotated with
+  `kilocode_change`, **check whether the marker encodes a bug fix or a feature
+  delta**. Bug fixes (missing `await`, defensive null-check, error capture)
+  usually need to be re-applied on top of the upstream refactor. Example from
+  v1.14.30: `Workspace.isSyncing` was missing an `await` — upstream's Effect
+  refactor reintroduced the same bug, so we had to port the fix into the new
+  `Effect.gen` block.
+- when a `take-theirs` drops a line that was the target of a Kilo pre-filter,
+  the upstream line may be actively wrong for Kilo — e.g. an inner `continue`
+  filter whose condition collides with an outer filter Kilo added. Re-read the
+  surrounding 20 lines before committing to `take-theirs`.
+- if Kilo-specific code must be refactored to fit new upstream architecture,
+  explain the refactor in the final summary
+- if upstream moved the relevant logic to another file, port the Kilo behaviour
+  there and list both paths in the final summary. Verify the new file already
+  carries the Kilo-renamed symbols (e.g. `x-kilo-directory`) by diffing against
+  pristine upstream.
+- if upstream deleted a file, analyse whether the Kilo behaviour should be
+  ported elsewhere or removed rather than restoring the deleted file
+- if tests fail only because upstream intentionally removed behaviour, remove
+  or update the obsolete tests rather than adding the old file back
+- do not modify unrelated files
+
+When removing code that existed in one side of a conflict, prefer
+**commenting it out with `kilocode_change` markers** over deletion when the
+surrounding structure (an `if`, a loop) still makes sense. That keeps the
+intent visible to the next merger. Example:
+
+```ts
+} else if (input?.scope !== "project" && !Flag.KILO_EXPERIMENTAL_WORKSPACES) {
+  // kilocode_change start - directory filtering handled by KiloSession.filters above
+  // if (input?.directory) {
+  //   conditions.push(eq(SessionTable.directory, input.directory))
+  // }
+  // kilocode_change end
+}
+```
+
+Use `TODO:` not `NOTE:` for follow-ups. `TODO` is searchable and implies an
+owner will act on it; `NOTE` reads as permanent commentary.
+
+### 6. Look for adjacent files the conflict forces you to touch
+
+Upstream restructures sometimes split one file into several (e.g. `permission.ts`
+→ `groups/permission.ts` + `handlers/permission.ts`). Only the *renamed* file
+shows up in `git diff --diff-filter=U`; the new sibling may need a Kilo feature
+ported in too. After resolving the flagged file, check:
+
+- files that import from the resolved file — do they compile?
+- files at paths implied by new imports (e.g. `../middleware/*`, `./handlers/*`)
+- `kilocode_change` comments in the *auto-merge* snapshot that didn't end up in
+  the working tree because the hosting file was renamed
+
+Add any such files to the plan as `hybrid` or `take-ours` with the same
+approval flow.
+
+### 7. Verify each resolution before moving on
+
+- confirm `script/upstream/find-conflict-markers.sh <file>` prints nothing
+- read the final file region (the new shape after edit) and sanity-check imports
+- for apparently-unused symbols upstream introduced, `grep` the file and the
+  rest of the package before deleting — they may be called from non-conflicted
+  code elsewhere. Example: `isTheme` in `theme.tsx` looked unused at the
+  resolution site but was called twice further down.
+- run the smallest relevant check (single `bun test` file, or `bun run
+  typecheck` in the touched package)
+- summarise the exact resolution, tradeoff, and verification result in chat
+- ask the user to approve the resolved file before staging it or resolving the
+  next one (for `medium` / `high`; `low` batches can be staged together)
+
+### 8. Run the full checks once everything is resolved
+
+- `git diff --name-only --diff-filter=U` returns empty
+- `bun run typecheck` from `packages/opencode/` (targeted) and from repo root
+  (catches non-conflicted call-site breakage)
+- relevant targeted tests. Tests that hang or time out in an unrelated part of
+  the graph may be pre-existing — note them, don't block the merge on them
+- `bun run script/check-opencode-annotations.ts` if `packages/opencode/` shared
+  files changed. Note that this tool compares against the merge base via `HEAD`
+  and will be silent until the merge commit lands
+- other CI guards that touched files imply (knip for `kilo-vscode/`,
+  `check-kilocode-change`, source-links, visual regression)
+
+### 9. Commit with the standard message
+
+Per `script/upstream/README.md`:
+
+```bash
+git commit -m "resolve merge conflicts"
+```
+
+The default `git merge` auto-message (`Merge branch '…' into …`) is also fine,
+but `resolve merge conflicts` is the convention for these PRs.
+
+### 10. Resync version strings in a separate commit
+
+Upstream stamps its own version into shared files — notably
+`packages/extensions/zed/extension.toml` (version field + 5 Kilo-Org download
+URLs), and any `package.json` that upstream bumped in the same release window.
+After the merge this leaves parts of the tree pointing at upstream's version
+(e.g. `1.14.30`), whose release tag does not exist on Kilo's pipeline, so the
+Zed download URLs silently 404.
+
+Fix this in a dedicated commit *after* `resolve merge conflicts`:
+
+```bash
+bun run script/sync-versions.ts             # uses root package.json version
+# or, to target an explicit version:
+bun run script/sync-versions.ts 7.2.41
+git add -A
+git commit -m "chore: resync versions after upstream merge"
+```
+
+The script rewrites every top-level `"version"` in `package.json` files
+(excluding `node_modules`, hidden dirs, and `packages/kilo-jetbrains/` which
+tracks its own cadence), plus the Zed extension toml. It is idempotent — rerun
+it any time to rebase the version back onto Kilo main (useful during
+long-running upstream merges where `main` releases in the meantime).
+
+Keeping this in its own commit makes reviewers' job easier: the merge commit
+only contains behavioural resolutions, and the version resync is a trivial
+diff they can skim in one glance.
+
+### 11. Write the PR body
+
+Structure the description so reviewers can skim:
+
+- **Non-trivial merge decisions**: a short section per file (or group of
+  related files) that required more than a mechanical `take-ours`/`take-theirs`.
+  Focus on *what Kilo behaviour survived* and *what upstream features were
+  adopted*. Link to Kilo PRs when a `kilocode_change` encodes a specific fix.
+- **Notable auto-merged changes**: new columns, new helper files, renamed
+  middleware — anything reviewers should eyeball even though git didn't flag
+  it.
+- **What to test**: explicit, scenario-level test steps for each non-trivial
+  change. Don't list tests; list *user-visible behaviour* so a tester who
+  doesn't read the diff can exercise it.
+- **CI guards to watch**: typecheck, knip, annotation check, visual regression.
+- **Follow-ups**: any `TODO:` you left in code, as a bullet list with links.
+
+## User-approval checkpoints
+
+Every manual merge decision requires explicit user approval **before applying**
+and **again after verification**. Be especially cautious when a decision is
+destructive, changes auth, billing, data deletion, public API compatibility,
+config schema behaviour, migrations, provider routing, or security posture.
+
+## Common pitfalls
+
+- Auto-merged code can reference declarations that still live inside conflict
+  blocks.
+- Related sibling files can need edits even when they are not listed as
+  unmerged — especially after upstream structural splits.
+- `renamed` should be used only when behaviour moves to a different file.
+- Function signatures can drift across conflict boundaries (args added, return
+  types widened). Grep for every call site before finalising.
+- Full-repo typecheck is the catch-all for non-conflicted call-site breakage.
+- Upstream can reintroduce bugs a Kilo `kilocode_change` had already fixed —
+  during big refactors check every `kilocode_change` the refactor touched.
+- "Take-theirs" on an inner conditional is often wrong when Kilo added an outer
+  pre-filter whose whole point was to widen what makes it to the inner block.
+- Apparently-unused upstream-added declarations may be called from
+  non-conflicted code elsewhere. Grep before deleting.
+- Stricter DOM lib types (upstream TS upgrade) can surface latent casting
+  issues around `WebSocket.send`, `Headers`, etc. — prefer narrowing the Kilo
+  type over adding `any` casts.

 The goal is to keep our diff from upstream as small as possible, making regular merges straightforward and reducing the risk of conflicts.

+`bun install` sets `merge.conflictStyle=zdiff3` repo-locally via `script/setup-git.ts` (wired into `postinstall`). Conflicts include the common ancestor between `|||||||` and `=======`, which is what `script/upstream/` and `mergiraf` rely on for structural resolution and what makes manual resolution on shared opencode files tractable.

 New files Kilo creates are always UTF-8 without a BOM. Encoding detection only runs when Kilo reads or overwrites an existing file.
 
 ## Not Supported
 
-- **UTF-16 without a BOM.** The byte pattern is ambiguous and cannot be distinguished reliably from other encodings. Save the file with a BOM or convert it to UTF-8.

 Encoding detection is statistical. Very short files, or files whose byte patterns happen to look like a different encoding, may occasionally be misidentified. If that happens, converting the file to UTF-8 is the most reliable workaround.

+
+# Message Feedback
+
+You can give a thumbs up or thumbs down to any response Kilo gives you. It's a quick way to tell us when something worked well, or when it didn't.
+
+{% callout type="info" %}
+Feedback is only available when telemetry is on. If you turn telemetry off, the buttons no longer display. See [Turning it off](#turning-it-off) below.
+{% /callout %}
+
+## How to use it
+
+{% tabs %}
+{% tab label="VSCode" %}
+
+When Kilo finishes a response, you'll see thumbs-up and thumbs-down buttons next to the **Copy response** button. Click one to send your rating. Click the same button again to take it back, or click the other one to change your mind.
+
+If you reload the window or switch to a different session, the feedback status will be reset.
+
+{% /tab %}
+
+{% tab label="CLI" %}
+
+In the terminal, two keybinds rate the most recent assistant message:
+
+| Action | Keybind |
+|---|---|
+| Helpful | `<leader>=` |
+| Not helpful | `<leader>-` |
+
+`<leader>` defaults to `Ctrl+X`, so you press `Ctrl+X` and then `=` for thumbs-up, or `Ctrl+X` and then `-` for thumbs-down.
+
+{% /tab %}
+{% /tabs %}
+
+## Why it matters
+
+Your feedback is the most direct way to tell us what's working and what isn't. We use it to tune the prompts behind Kilo's behavior, pick better default models, and find and fix problems faster than we could on our own.
+
+## What we send
+
+When you rate a response, here's what gets sent:
+
+- That you rated a response thumbs up or thumbs down.
+- The provider and model ID that produced the response (for example, `anthropic` and `claude-sonnet-4-5`).
+- For responses that came through Kilo Gateway, the request ID so we can match the rating back to the session.
+
+No further information is included in the rating feedback. For more information on telemetry, see [PRIVACY.md](https://github.com/Kilo-Org/kilocode/blob/main/PRIVACY.md).
+
+## Turning it off
+
+Feedback is part of telemetry, so turning telemetry off will cause the feedback buttons to no longer appear.
+
+{% tabs %}
+{% tab label="VSCode" %}
+
+Open Settings (`Cmd+,` on Mac, `Ctrl+,` on Windows/Linux), search for **`telemetry.telemetryLevel`**, and set it to **Off**. The feedback buttons will no longer appear. Set it back to **All** to bring them back. (For more on what this setting controls, see [VS Code's telemetry docs](https://code.visualstudio.com/docs/getstarted/telemetry).)
+
+{% /tab %}
+
+{% tab label="CLI" %}
+
+Set `KILO_TELEMETRY_LEVEL=off` in your environment before starting Kilo:
+
+```bash
+KILO_TELEMETRY_LEVEL=off kilo
+```
+
+With telemetry off, pressing the feedback keybinds shows a message saying feedback is disabled, and nothing is sent.

 # kilo-code
 
+## 7.2.42
+
+### Minor Changes
+
+- [#9909](https://github.com/Kilo-Org/kilocode/pull/9909) [`9ffd047`](https://github.com/Kilo-Org/kilocode/commit/9ffd047962039d6b73d301d5d4e67560cd501c4f) - Detect and preserve UTF-32 (LE and BE) with BOM when reading and editing files. UTF-16 and UTF-32 without a BOM remain unsupported.
+
+### Patch Changes
+
+- [#9939](https://github.com/Kilo-Org/kilocode/pull/9939) [`8ed0e17`](https://github.com/Kilo-Org/kilocode/commit/8ed0e17855baee32d48fa44881761a8ee6b53f1e) - Recover Agent Manager worktrees after restart when saved state is missing, corrupt, or stale.
+
+- [#9887](https://github.com/Kilo-Org/kilocode/pull/9887) [`d9453f0`](https://github.com/Kilo-Org/kilocode/commit/d9453f0da2b063041f6f98235220cde9129e162d) - Fix queued-turn auto-compaction so overflow recovery runs instead of exhausting compaction attempts.
+
+- [#9855](https://github.com/Kilo-Org/kilocode/pull/9855) [`59e8eff`](https://github.com/Kilo-Org/kilocode/commit/59e8effc3df8a03146f5ceddf95f79989b813417) - Respect project-specific semantic indexing decisions instead of enabling indexing globally across workspaces.
+

The extension now defaults `NODE_USE_SYSTEM_CA=1` on the spawned CLI process so users behind MITM proxies (Zscaler, Netskope, Palo Alto, etc.) no longer hit TLS errors on sign-in. A new `kilo-code.new.extraCaCerts` setting accepts a PEM file path for additional CAs, and `http.proxyStrictSSL=false` is honored as an opt-out from verification.

+
+- [#9855](https://github.com/Kilo-Org/kilocode/pull/9855) [`59e8eff`](https://github.com/Kilo-Org/kilocode/commit/59e8effc3df8a03146f5ceddf95f79989b813417) - Respect project-specific semantic indexing decisions instead of enabling indexing globally across workspaces.
+
+- [#9928](https://github.com/Kilo-Org/kilocode/pull/9928) [`520922f`](https://github.com/Kilo-Org/kilocode/commit/520922ff39354c2df72317dee0f70035c52c24c5) Thanks [@shssoichiro](https://github.com/shssoichiro)! - Prevent VS Code empty windows from starting codebase indexing against the home directory.
+
+- [#9843](https://github.com/Kilo-Org/kilocode/pull/9843) [`27d14d4`](https://github.com/Kilo-Org/kilocode/commit/27d14d432c33051e4bdd5863ea14b207758e9234) - Prompt before reading `.env` files even after broad read permissions were previously approved.

+- [#9924](https://github.com/Kilo-Org/kilocode/pull/9924) [`914bbdf`](https://github.com/Kilo-Org/kilocode/commit/914bbdfd0575e40554c39c6691e4264a63109953) Thanks [@shssoichiro](https://github.com/shssoichiro)! - Restore Skill tool access for Plan, Ask, Explore, and other non-system agents so skill workflows are available by default.
+
+- [#9907](https://github.com/Kilo-Org/kilocode/pull/9907) [`d9d4dcd`](https://github.com/Kilo-Org/kilocode/commit/d9d4dcd37c6719652252da66b6a1ce27049beb47) - Recover sessions left unable to continue after an assistant turn was created but never started.

 ## Current State
 
-- `KILO_EXPERIMENTAL_HTTPAPI` gates the bridge. Default behavior still uses Hono.
-- The bridge mounts selected paths in `server/routes/instance/index.ts` before legacy Hono routes.
-- Legacy Hono routes remain for default behavior and for `hono-openapi` SDK generation.
-- `HttpApi` auth is independent of Hono auth.
-- `Authorization` is attached in each route module, not centrally wrapped in `server.ts`.
+- `KILO_EXPERIMENTAL_HTTPAPI` selects the backend at server startup. Default is still `hono`.
+- `server/backend.ts` picks one of `effect-httpapi` or `hono`; `server.ts` builds either a pure Effect `HttpApi` web handler or the legacy Hono app accordingly. The earlier in-Hono "bridge" model has been replaced by this fork-at-startup.
+- Legacy Hono routes remain mounted for the `hono` backend and remain the source for `hono-openapi` SDK generation.
+- An Effect `HttpApi` OpenAPI surface exists (`OpenApi.fromApi(PublicApi)` in `cli/cmd/generate.ts --httpapi`, `KILO_SDK_OPENAPI=httpapi` in `packages/sdk/js/script/build.ts`) but is opt-in. The default SDK generation is still Hono.
+- `httpapi/public.ts` carries the Hono-compat normalization for the Effect-generated OpenAPI surface (auth scheme strip, request-body required flag, optional `null` arms, `BadRequestError` / `NotFoundError` remap, `$ref` self-cycle fix, `auth_token` query injection). Today's Effect-generated SDK is not byte-identical to the Hono-generated SDK — see Phase 4.
+- Auth is centrally configured for the Effect backend via Effect `Config` (`refactor: use Effect config for HttpApi authorization`, `Fix HttpApi raw route authorization`) rather than re-attached in each route module.
 - Auth supports Basic auth and the legacy `auth_token` query parameter through `HttpApiSecurity.apiKey`.
 - Instance context is provided by `httpapi/server.ts` using `directory`, `workspace`, and `x-kilo-directory`.
 - `Observability.layer` is provided in the Effect route layer and deduplicated through the shared `memoMap`.
+- CORS middleware is wired into both backends (`feat(httpapi): add CORS middleware to instance routes`).
 
 ## Migration Rules
 
@@ -122,13 +124,30 @@ Keep large or stateful groups for later:
 
 Hono routes cannot be deleted while `hono-openapi` is the source of SDK generation.
 
+Status: the Effect `HttpApi` OpenAPI surface is **implemented and opt-in** (`bun dev generate --httpapi`, `KILO_SDK_OPENAPI=httpapi`). Default SDK generation still uses Hono. `httpapi/public.ts` applies the Hono-compat normalization layer to the Effect output. Diff against the Hono-generated spec still shows real gaps that must be closed before the SDK can flip:
+
+- Branded-type `pattern` constraints on ID schemas are not propagated to the Effect output (~169 missing).
+- Per-property `description` annotations are not propagated through `Schema.Struct` to the Effect output (~107 missing).
+- `Event.*` and `SyncEvent.*` component names use dotted form in Hono and PascalCase in Effect (~50 differences, breaks SDK type names).
+- Effect's component deduper emits numbered duplicates (`Session9`, `SyncEvent.session.updated.11`) that need a name-collision fix.
+- Cosmetic-only diffs (`additionalProperties: false`, `const` vs `enum`, MAX_SAFE_INTEGER `maximum`, `propertyNames`) can be normalized in `public.ts` if they would otherwise change SDK output.
+
 Required before route deletion:
 
-- Generate the public OpenAPI surface from Effect `HttpApi` for ported routes.
+- Close the diff above so Effect-generated SDK output matches the Hono-generated SDK output for every retained path.
 - Keep operation IDs, schemas, status codes, and SDK type names stable unless the change is intentional.
+- Flip `packages/sdk/js/script/build.ts` default to `httpapi` and regenerate.
 - Compare generated SDK output against `dev` for every route group deletion.
 - Remove Hono OpenAPI stubs only after Effect OpenAPI is the SDK source for those paths.
 
+V2 cleanup once SDK compatibility no longer needs the legacy Hono contract:
+
+- Remove `public.ts` compatibility transforms that hide honest `HttpApi` metadata, including auth `securitySchemes`, per-route `security`, and generated `401` responses.
+- Stop remapping built-in `HttpApi` error schemas back to legacy Hono `BadRequestError` / `NotFoundError` components if V2 clients can consume the actual Effect error shape.
+- Prefer the direct `HttpApi` OpenAPI output for request/response bodies and named component schemas instead of rewriting it to match Hono generator quirks.
+- Keep schema fixes that describe the actual wire format, but delete transforms that only preserve legacy SDK type names or inline-vs-ref shape.
+- Re-evaluate `auth_token` as an OpenAPI security scheme rather than a hand-injected query parameter once clients can consume the V2 spec.

+This is a plugin to simulate a remote environment locally. Add this to `.opencode/opencode.jsonc`:
+
+```json
+  "plugin": ["../packages/opencode/src/control-plane/dev/debug-workspace-plugin.ts"],
+```
+
+In a separate terminal, run a separate OpenCode server. This will act like a remote server and the local instance will proxy all requests to it:
+
+```
+./packages/opencode/script/run-workspace-server
+```
+
+With the plugin install, you can now run OpenCode and create a `debug` workspace type. This will create a "remote" workspace which talks to the second workspace server started above.
+
+How this works:
+
+- The workspace server needs to know the workspace id and port to run. It waits for this information to be written to a file and starts the server when the data is written.
+- The debug plugin writes this information in the `create` call to the workspace. So create a `debug` workspace will always kick off a new external server.
+- The server script watches for file changes, so whenver you create a new `debug` workspace it will restart with the new information. This means that there is only ever one working `debug` workspace at a time; when you create a new one all previous sessions will show that it can't connect because previous debug workspaces do not exist.

+ * KiloClaw chat slash-command autocomplete.
+ *
+ * Slim port of `cli/cmd/tui/component/prompt/autocomplete.tsx` — drops the
+ * `@`-mode branches (file mentions, agents, MCP resources, frecency,
+ * extmark wiring) and only handles `/` slash commands.
+ *
+ * Source of slash commands is supplied by the caller via the `slashes`
+ * prop. We intentionally do NOT pull from `useCommandDialog().slashes()`
+ * because that registry holds globally-registered commands across all
+ * routes (e.g. the home route's `/new` for sessions), which would clash
+ * with kiloclaw's own `/new` for conversations.
+ *
+ * Mounts as an absolutely-positioned popup above the chat textarea and
+ * suspends the global command keybinds while open so arrow keys drive the
+ * popup instead of triggering palette commands.

  *
- * Headless Stream Chat JS SDK integration for the TUI.
- * Uses the same channel/credentials as the web dashboard's ChatTab.
+ * Hosts the HTTP and WebSocket clients, exposes a multi-conversation API
+ * (list/create/select/rename/delete), and translates Kilo Chat events for
+ * the active conversation into the legacy `ChatMessage` shape that the
+ * existing single-pane renderer consumes.
  *
- * stream-chat is dynamically imported to avoid crashing Bun at module
- * load time (follow-redirects uses Error.captureStackTrace in a way
- * that is incompatible with Bun's runtime).
+ * Switching the active conversation rotates the WebSocket subscription so
+ * we only ever stream events for the conversation the user is looking at.

+# Instance Route Parity
+
+This directory contains the legacy Hono instance routes and the experimental Effect HttpApi implementation under `httpapi/`. Keep them behaviorally aligned.
+
+- When adding, removing, or changing a legacy Hono route, update the matching Effect HttpApi group and handler in `httpapi/` in the same change unless the route is intentionally unsupported.
+- When changing an Effect HttpApi route, verify the legacy Hono route has the same public behavior, request shape, response shape, status codes, and instance/workspace routing semantics.
+- Keep OpenAPI/SDK-visible schemas aligned. If a difference is only an OpenAPI generation artifact, prefer fixing the source schema first; use `httpapi/public.ts` normalization only for compatibility shims that cannot be represented cleanly in the source schema.
+- Add or update parity coverage in `test/server/httpapi-bridge.test.ts` or the focused HttpApi tests when behavior or schema parity could regress.

+# HttpApi Route Patterns
+
+Use `HttpApiBuilder.group(...)` for normal HTTP endpoints, including streaming HTTP responses such as server-sent events. Handlers should yield stable services once while building the handler layer, then close over those services in endpoint implementations.
+
+```ts
+export const sessionHandlers = HttpApiBuilder.group(InstanceHttpApi, "session", (handlers) =>
+  Effect.gen(function* () {
+    const session = yield* Session.Service
+
+    return handlers.handle("list", () => session.list())
+  }),
+)
+```
+
+For SSE endpoints, stay in `HttpApiBuilder.group(...)` and return `HttpServerResponse.stream(...)` from the handler. Annotate the endpoint success schema with `HttpApiSchema.asText({ contentType: "text/event-stream" })` so OpenAPI documents the stream content type.
+
+Use raw `HttpRouter.use(...)` only for routes that do not fit the request/response HttpApi model, such as WebSocket upgrade routes or catch-all fallback routes. Yield stable services at route-layer construction and close over them in `router.add(...)` callbacks.
+
+```ts
+export const rawRoute = HttpRouter.use((router) =>
+  Effect.gen(function* () {
+    const pty = yield* Pty.Service
+
+    yield* router.add("GET", PtyPaths.connect, (request) => connectPty(request, pty))
+  }),
+)
+```
+
+Avoid `Effect.provide(SomeLayer)` inside request handlers or raw route callbacks. Stable layers should be provided once at the application/layer boundary, not rebuilt or scoped per request.
+
+Avoid `HttpRouter.provideRequest(...)` unless the dependency is intentionally request-level. Prefer `HttpRouter.use(...)` for stable app services.
+
+Use `Effect.provideService(...)` in middleware only for request-derived context, such as `WorkspaceRouteContext`, `InstanceRef`, or `WorkspaceRef`. Do not use it to smuggle stable services through request effects when they can be yielded at layer construction.
+
+When adding middleware, compose it at the layer boundary and keep the route tree explicit in `server.ts`. Shared router middleware such as auth, workspace routing, and instance context should stay visible where routes are assembled.

 Remember that you can call multiple tools in one response.
 Use semantic_search to search for high level concepts or descriptions of functionality in the user's question. This is the best place to start if you don't know where to look or the exact strings found in the codebase.
 Prefer search_workspace_symbols over grep_search when you have precise code identifiers to search for.

+// Regression guard for branding drift in user-facing MCP strings.
+//
+// History: upstream OpenCode has repeatedly overwritten the Kilo-branded
+// toast message and MCP client `name` field during large refactors — most
+// recently in upstream PR #22913 (commit 5fccdc9fc, "refactor: collapse mcp
+// barrel into mcp/index.ts") which Kilo picked up via the v1.4.7 merge (PR
+// #9346, commit 57630eaf1). The original fix was PR #7174.
+//
+// This test asserts the surviving Kilo-branded strings directly against the
+// source so that the next upstream churn on this file fails the Kilo test
+// suite instead of shipping an "opencode mcp auth" popup to end users.

+# Server Test Guide
+
+Use these patterns for server and HttpApi middleware tests in this directory.
+
+- Prefer focused middleware tests with tiny fake routes over full API route trees when testing routing, context, proxying, or middleware policy.
+- Use `testEffect(...)` with `NodeHttpServer.layerTest` for the primary in-test server and make relative `HttpClient` requests against it.
+- Use `HttpRouter.add(...)` probe routes that expose the context under test, such as `WorkspaceRouteContext`, `InstanceRef`, or `WorkspaceRef`.
+- Compose middleware in the same order as production when testing interactions, for example `instanceRouterMiddleware.combine(workspaceRouterMiddleware)`.
+- For secondary upstream servers, build Effect `NodeHttpServer.layer(...)` into the current test scope with `Layer.build(...)` so the listener stays alive until the test scope exits.
+- Avoid `Bun.serve` when testing Effect HTTP middleware. Keep the test in the Effect HTTP stack unless the production path being tested is Bun-specific.
+- For WebSocket paths, use `Socket.makeWebSocket(...)` from the test client and assert protocol forwarding or frame relay when relevant.
+- Use scoped test layers for flags, database reset, and other global mutable state. Restore flags and reset state in finalizers.
+- Use `tmpdirScoped({ git: true })` plus `Project.use.fromDirectory(dir)` for project-backed requests.
+- If a test needs persisted state without matching runtime state, keep direct database setup inside a narrowly named helper that explains that state.
+- Add comments for non-obvious test topology, especially tests involving both the local test server and a fake upstream server.

+// kilocode_change - new file
+// Sync every Kilo version string across the monorepo to a single target.
+//
+// Why this exists: upstream opencode stamps its own version into shared files
+// during each release (notably `packages/extensions/zed/extension.toml`). When
+// we merge upstream, that churn either produces conflicts or silently leaves
+// our packages pointing at upstream's version — and upstream's version tag
+// doesn't exist on our release pipeline, so the resulting download URLs 404.
+//
+// Run this in a dedicated commit after resolving an upstream merge (see
+// `.kilo/command/upstream-manual-merge.md`). It's also handy mid-merge to
+// rebase our version bumps onto any new Kilo main releases.
+//
+// Usage:
+//   bun run script/sync-versions.ts            # use root package.json version
+//   bun run script/sync-versions.ts 7.2.41     # explicit target
+//   bun run script/sync-versions.ts v7.2.41    # leading `v` is stripped
+//
+// What gets updated:
+//   - every `package.json` top-level `"version": "..."` field in the repo
+//     (excluding node_modules and hidden directories)
+//   - `packages/extensions/zed/extension.toml` top-level `version = "..."`
+//   - the five Kilo-Org download URLs inside that toml
+//
+// Intentionally NOT touched:
+//   - `packages/kilo-jetbrains/**` — the JetBrains plugin has its own release
+//     cadence and version number.
+//   - dependency version strings inside `package.json` — internal deps use

+Usage:
+  bun run script/upstream/find-reset-candidates.ts [path] [options]
+
+Arguments:
+  path                     Optional repo-relative subdirectory to scope to.
+                           Defaults to all tracked shared paths.

+  --review-limit <n>       Max non-marker, non-whitespace diff lines that

+  --dry-run                Classify and report only; do not write any files.
+  --concurrency <n>        Parallel classifications (default: 8).
+```
+
+The command pre-filters with `git diff --name-only <last-merged-upstream>..HEAD` and drops:
+
+- Kilo-only paths: anything under `packages/kilo-*/`, any `**/kilocode/**` subdir, `script/upstream/`.
+- Non-code assets: SVG, PNG, fonts, archives, lock files, etc. (see `SKIP_EXTENSIONS` / `SKIP_FILENAMES` in the script).
+- Files covered by the merge config's `keepOurs` or `skipFiles` lists in `utils/config.ts` — these are intentionally preserved or removed in Kilo and must not be bulk-reset.
+
+It then issues one `git cat-file --batch-check` for all remaining paths to grab upstream blob sizes in a single subprocess. Files absent upstream land in `upstream-missing` immediately; files above 256 KB land in `too-large` (generated manifests, giant snapshots). Only the survivors get fetched via `git show` and classified:
+
+| Bucket | Meaning | Action |
+|---|---|---|
+| `identical` | Local bytes already match transformed upstream (branding-only drift in raw git diff) | none |
+| `markers-only` | Stripping `kilocode_change` markers makes local match upstream | reset |
+| `cosmetic-only` | Non-marker diff is only whitespace or reordered lines (the line multiset is identical) | reset |
+| `small-diff` | ≤ `--review-limit` non-marker, non-cosmetic diff lines | reset |
+| `large-diff` | > `--review-limit` non-marker, non-cosmetic diff lines | skipped |
+| `upstream-missing` | File does not exist upstream (kilo-only, intentional) | skipped |
+| `local-missing` | File tracked but missing locally (deleted in Kilo) | skipped |
+| `binary-diff` | Binary file differs | skipped (use `reset-to-upstream.ts` per file) |
+| `binary-identical` | Binary file already matches | none |
+| `too-large` | Upstream blob > 256 KB | skipped (use `reset-to-upstream.ts` per file) |
+
+Line counting uses an in-process multiset diff (pure JS, no subprocess) for speed and robustness against concurrent git output stalls on big files. Moved/reordered lines therefore count as zero drift, which is usually what you want for "is this file meaningfully different from upstream".
+
+`markers-only`, `cosmetic-only`, and `small-diff` buckets are auto-reset unless `--dry-run` is passed. A markdown summary is printed to stdout so you can review what happened and spot-check the resulting `git diff`. All resets land as uncommitted working-tree changes; `git diff` / `git checkout` is your safety net.
+
+Tighten the blast radius with `--review-limit 0` (only `markers-only` and `cosmetic-only`) or by scoping with a `path` argument (e.g. `packages/opencode/src/mcp`).
+
 ## Using Custom Base Branches
 
 By default, upstream merges start from the `main` branch. However, you can use `--base-branch` to start from a different branch. This is useful for:
 
+Passing `--base-branch HEAD` targets the currently checked-out branch without typing its full name.
+
 ### Incremental Merges
