Learning: In Astro-Han/pawwork (`packages/app/src/pages/layout/sidebar-items.tsx`), the `indicator()` function in `SessionRow` intentionally renders `props.leadingSlot` (the pin button) only as a fallback when no status indicator (running/permission/error/unseen) is active. When a higher-priority status wins the slot, the pin button is removed from the DOM — this is a deliberate design choice for the merged leading slot (`#150`). The keyboard unpin path is preserved via: (1) focusing the row anchor triggers `group-focus-within` which reveals the dots menu trigger, then Tab → Enter → "Unpin Session"; (2) the context menu (right-click / Shift+F10) exposes "Unpin Session". The "always render + CSS overlay" approach was considered but rejected due to z-index/pointer-events complexity; residual `...` slot behavior is tracked in `#192`. Do NOT flag the absence of the pin button from the DOM when a status is active as an accessibility regression.

Learning: In Astro-Han/pawwork (`packages/opencode/src/patch/index.ts`), the BOM-transition surfacing gap — where `Bom.split` strips BOM before building `unified_diff`/`new_content` but `Bom.join` later re-attaches BOM on disk write, meaning BOM changes are not reflected in the diff payload — is intentionally deferred. PR `#270` is an upstream-sync graft; fixing the issue here would mix refactor + bugfix intents and drift the diff from the upstream baseline needed for clean future grafts. A dedicated follow-up PR (or upstream report) will address this. Do NOT re-flag the missing BOM-change surfacing in `ApplyPatchFileUpdate`/`ApplyPatchFileChange` as a blocking issue in PR `#270` or in future sync PRs that carry the same upstream baseline.

Learning: In pawwork (Astro-Han/pawwork), prefer using `createStore` instead of multiple `createSignal` calls only when the signals represent **coupled** object state that is updated together (i.e., there is at least one shared batch-update site where the state is changed in the same transaction). If the state fields are **independent** and are mutated by separate handlers (e.g., one handler updates only `selectedSkill` while another updates only `mode`), keep them as individual `createSignal` calls—using `createStore` for truly independent fields adds boilerplate without behavioral benefit.

Learning: This repo configures Tailwind v4 with `--color-*: initial`, which effectively breaks standard Tailwind palette utilities (e.g., `text-violet-500` can resolve to no CSS variable and render as a no-op/black). For brand/accent colors that are not backed by semantic design tokens, use inline styles with the exact hex value (e.g., `style={{ color: '#8B5FBF' }}` / `homeIconStyle: { color: '#8B5FBF' }`) and add a short comment explaining that Tailwind palette utilities won’t work due to the `--color-*: initial` setup. Do not suggest replacing these inline hex colors with Tailwind palette classes anywhere in this repo.

Learning: In Astro-Han/pawwork E2E tests (e.g., *.spec.ts under packages/app/e2e), reaching a real "running" session state is not achievable with the bare `sdk` fixture. Use the `project` fixture (to bootstrap the model) and orchestrate the transition with `llm.wait(1)`; even if you set `agent: "build"` and a `system` prompt via `sdk.session.promptAsync`, the current test infrastructure does not trigger an actual LLM call, so it won’t simulate "running" cheaply. Review any attempt to mock/force "running" using only `sdk` as likely ineffective unless it also uses `project` + `llm.wait(1)`.

Learning: In Astro-Han/pawwork E2E tests under packages/app/e2e, do not manually call `project.trackSession(sessionID)` when you obtain a `sessionID` via `project.prompt(text)`. The `project.prompt()` implementation already registers `trackSession(next.sessionID, active.directory)` automatically after the prompt submission is observed and the active session is resolved, so calling `project.trackSession(sessionID)` again will create duplicate session ownership/teardown handling.

Learning: For Astro-Han/pawwork E2E tests under packages/app/e2e/**/*.spec.ts, do not call project.trackDirectory() or project.trackSession() before project.open() has run. The project fixture throws until open() initializes internal state. Use this ordering pattern: (1) call project.trackSession(sessionID) inside the beforeGoto callback (where state is already available), (2) call project.trackDirectory(directory) and any cross-workspace tracking like project.trackSession(id, directory) immediately after project.open() returns, and (3) if you create any resources before open() that cannot yet be tracked via the fixture, ensure you clean them up explicitly in finally blocks (e.g., cleanupSession / cleanupTestProject).

Learning: In E2E parity tests, prefer using the existing `[data-action]` coverage when asserting UI parity. For elements whose trigger props set `data-action` (e.g., `data-action="prompt-model"` and `data-action="prompt-model-variant"` on prompt input chip triggers), you generally do not need to add separate assertions driven by `[data-component]` for parity. Avoid duplicating component-specific queries when the `[data-action]` selector sweep already includes the elements; any extra unioning of selectors should be treated as optional belt-and-suspenders rather than required.

Learning: In Astro-Han/pawwork (`packages/ui/src/components/message-part.tsx`), the `taskId` createMemo and `childSessionId` createMemo both intentionally read only from `partMetadata().sessionId` (populated post-execution), not from `input.task_id` / `input.subagent_session_id`. This has always been the case — the original code never read the input field either. Adding an `input.subagent_session_id` fallback would be a new capability, not a bug fix. Do NOT flag the absence of this fallback as a regression in PR `#247` or future PRs unless there is a concrete case where metadata is not populated.

Learning: In Astro-Han/pawwork `packages/app/src/components/prompt-input.tsx`, after the composer unification in PR `#208` (fixed in commit 5d810aa):
- `SendButton.disabled` does NOT gate on `store.mode !== "normal"`. Shell mode has a fully visible, clickable orange submit button that calls `handleSubmit` directly (same path as the Enter key in `handleKeyDown`). Do NOT suggest re-adding the mode gate.
- `SendButton` does NOT use the `buttons()` spring opacity animation (`style={buttons()}`). It is always fully visible regardless of mode.
- `WorkspaceChip` is gated on `props.homeMode && store.mode === "normal"` so it hides in shell mode (preventing it from appearing isolated/bright while neighboring controls fade).
- The left-side chip group (`aria-hidden={store.mode !== "normal"}`) covers attach/model/variant/workspace controls only; `SendButton` remains in a separate right-side sibling div.

Timestamp: 2026-04-28T06:47:20.342Z
Learning: In Astro-Han/pawwork, `packages/opencode/src/tool/question.ts` is a permanent PawWork carve-out: `Question.Prompt` (defined in `packages/opencode/src/question/index.ts`) remains a Zod schema, NOT an Effect Schema. The `ts-expect-error` boundary in `tool/registry.ts` marks the Zod ↔ Effect Schema seam. The dropped `packages/opencode/test/tool/question.test.ts` covered the old Zod-mixed surface. Schema-bound regression tests for this tool are intentionally deferred until `question/index.ts` migrates to Effect Schema in its own dedicated PR. Do NOT request restoring question tool tests in upstream-sync PRs; flag it only in the PR that migrates `question/index.ts` to Effect Schema.

Timestamp: 2026-04-24T00:02:50.599Z
Learning: For Astro-Han/pawwork E2E tests under packages/app/e2e/**/*.spec.ts, do not call project.trackDirectory() or project.trackSession() before project.open() has run. The project fixture throws until open() initializes internal state. Use this ordering pattern: (1) call project.trackSession(sessionID) inside the beforeGoto callback (where state is already available), (2) call project.trackDirectory(directory) and any cross-workspace tracking like project.trackSession(id, directory) immediately after project.open() returns, and (3) if you create any resources before open() that cannot yet be tracked via the fixture, ensure you clean them up explicitly in finally blocks (e.g., cleanupSession / cleanupTestProject).

Learning: In `packages/opencode/test/file/ripgrep.test.ts` (Astro-Han/pawwork, PR `#270`), the `files dies on nonexistent directory` test hardcodes `/tmp/nonexistent-dir-12345` as the missing-directory path. This is upstream-inherited behaviour adopted wholesale via the graft strategy (`project_upstream_strategy.md`). The fix — replacing the hardcoded path with a platform-neutral guaranteed-nonexistent child path derived from the `tmpdir` fixture — is intentionally deferred to a follow-up PR or upstream report, to avoid mixing bugfix + refactor intents and drifting the diff from the upstream baseline future syncs need. Do NOT re-flag the hardcoded `/tmp/nonexistent-dir-12345` path in this file as a blocking or actionable issue until the follow-up PR lands.

Timestamp: 2026-04-23T15:25:27.182Z
Learning: In Astro-Han/pawwork E2E tests (e.g., *.spec.ts under packages/app/e2e), reaching a real "running" session state is not achievable with the bare `sdk` fixture. Use the `project` fixture (to bootstrap the model) and orchestrate the transition with `llm.wait(1)`; even if you set `agent: "build"` and a `system` prompt via `sdk.session.promptAsync`, the current test infrastructure does not trigger an actual LLM call, so it won’t simulate "running" cheaply. Review any attempt to mock/force "running" using only `sdk` as likely ineffective unless it also uses `project` + `llm.wait(1)`.

Learning: In `packages/opencode/test/file/ripgrep.test.ts` (Astro-Han/pawwork, PR `#270`), the tests intentionally use a local `run` helper (`effect.pipe(Effect.provide(Ripgrep.defaultLayer), Effect.runPromise)`) rather than the `testEffect(...)` harness. This file was adopted from upstream wholesale as part of an upstream-sync graft; migrating to `testEffect` + `it.live(...)` was deferred to a separate follow-up PR to avoid mixing refactor and harness-migration intents within the sync. Do NOT re-flag the local `run` wrapper as needing harness migration until that follow-up lands.

Timestamp: 2026-04-23T07:23:23.849Z
Learning: In pawwork (Astro-Han/pawwork), prefer using `createStore` instead of multiple `createSignal` calls only when the signals represent **coupled** object state that is updated together (i.e., there is at least one shared batch-update site where the state is changed in the same transaction). If the state fields are **independent** and are mutated by separate handlers (e.g., one handler updates only `selectedSkill` while another updates only `mode`), keep them as individual `createSignal` calls—using `createStore` for truly independent fields adds boilerplate without behavioral benefit.

Timestamp: 2026-04-23T15:10:21.635Z
Learning: This repo configures Tailwind v4 with `--color-*: initial`, which effectively breaks standard Tailwind palette utilities (e.g., `text-violet-500` can resolve to no CSS variable and render as a no-op/black). For brand/accent colors that are not backed by semantic design tokens, use inline styles with the exact hex value (e.g., `style={{ color: '#8B5FBF' }}` / `homeIconStyle: { color: '#8B5FBF' }`) and add a short comment explaining that Tailwind palette utilities won’t work due to the `--color-*: initial` setup. Do not suggest replacing these inline hex colors with Tailwind palette classes anywhere in this repo.
