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/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.

Learning: In Astro-Han/pawwork (`packages/opencode/src/session/prompt.ts` and `packages/opencode/src/session/processor.ts`, PR `#264`), the loop-gate race condition between `buildLoopContext()` and `recordSyntheticBlock`/`recordSyntheticStop` is intentionally handled via idempotence guards (re-check sigKey presence / `hasStopped` inside the record helpers) rather than a full per-parent `Effect.Mutex`. Threading a `Map<MessageID, Mutex>` through the processor was considered too large a surface change for this edge case; the residual TOCTOU window only produces extra synthetic parts with no behavioral drift on the "turn ends" contract. A code comment documents the trade-off and points to a full-mutex follow-up if the race is observed in practice. Do NOT re-flag the absence of a per-parent mutex as a blocking issue in future reviews.

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: In Astro-Han/pawwork (`packages/opencode`), the canonical module-as-namespace pattern is: each module file ends with `export * as <ModuleName> from "./<module-file>"` (e.g., `export * as SubagentRun from "./subagent-run"` at the bottom of `subagent-run.ts`). Consumers then import the namespace as a named binding (`import { SubagentRun } from "../session/subagent-run"`) and access members via `SubagentRun.Service`, `SubagentRun.defaultLayer`, `SubagentRun.AgentListFilter`, etc. This self-reexport is load-bearing — without it the named binding resolves to nothing. This pattern is used uniformly across session/, config/, tool/, provider/, etc. Do NOT flag these self-reexports as dead code or redundant in any file.

The correct assertion strategy is to check `expect(text).not.toContain("secret")` and `expect(text).not.toContain("PawWork")`.

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: 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).

Timestamp: 2026-04-24T05:48:36.205Z
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/opencode/src/session/prompt.ts` and `packages/opencode/src/session/processor.ts`, PR `#264`), the loop-gate race condition between `buildLoopContext()` and `recordSyntheticBlock`/`recordSyntheticStop` is intentionally handled via idempotence guards (re-check sigKey presence / `hasStopped` inside the record helpers) rather than a full per-parent `Effect.Mutex`. Threading a `Map<MessageID, Mutex>` through the processor was considered too large a surface change for this edge case; the residual TOCTOU window only produces extra synthetic parts with no behavioral drift on the "turn ends" contract. A code comment documents the trade-off and points to a full-mutex follow-up if the race is observed in practice. Do NOT re-flag the absence of a per-parent mutex as a blocking issue in future reviews.

Timestamp: 2026-04-23T15:26:07.250Z
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.

Timestamp: 2026-04-28T04:38:11.771Z
Learning: In Astro-Han/pawwork (`packages/opencode/src/tool/agent.ts`), the `subagent_session_id` field in the `Parameters` schema accepts any `Schema.String` rather than a branded `SessionID`. This is inherited upstream behavior (adopted in PR `#270`, an upstream-sync graft of upstream PR `#23244`). The fix — validating `subagent_session_id` as a `SessionID` brand up front so malformed/typo'd IDs fail explicitly rather than silently forking a new subagent session — is intentionally deferred to a follow-up PR or upstream report. Do NOT re-flag this as a blocking issue in PR `#270` or in future upstream-sync PRs that carry the same schema; flag it only in a PawWork-authored PR that touches `agent.ts` parameter validation.

Learning: In `packages/opencode/test/session/subagent-lifecycle-integration.test.ts` (Astro-Han/pawwork, PR `#287`), the test suite intentionally uses a manual `run` helper (`Effect.runPromise(program.pipe(Effect.provide(Layer.mergeAll(SubagentRun.defaultLayer, Session.defaultLayer)), Effect.orDie))`) and raw `bun:test` test cases rather than the `testEffect(...)` harness. All 27 lifecycle tests pass with this pattern. Migration to `testEffect` + `it.live(...)` is deferred to a dedicated test-harness sweep PR to avoid fixture drift before merge. Do NOT re-flag the manual `Effect.runPromise` runner in this file as needing harness migration until that sweep PR lands.

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.

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.

Learning: In Astro-Han/pawwork E2E tests (packages/app/e2e/fixtures.ts), `project.prompt(text)` internally calls `trackSession(next.sessionID, active.directory)` after the prompt submission is observed and the active session is resolved. Tests that obtain a `sessionID` from `project.prompt()` do NOT need to call `project.trackSession(sessionID)` manually — it is already registered for teardown. Calling it again would be duplicate ownership.

Learning: In `packages/opencode/src/session/session.ts` (Astro-Han/pawwork, PR `#287`), the `updatePart` subtask guard intentionally allows first writes (where `existing === undefined`) to pass through without calling `lifecycleFieldsChanged`. This is required for `Session.fork()`, migration, and import paths that replay historical `SubtaskPart` rows via `updatePart()` outside any `SubagentRunWriterContext`. Only mutations of an already-persisted row (`existing` is defined) are policed. Do NOT suggest adding a lifecycle check on first-write in this guard.

Learning: In `packages/opencode/src/tool/agent.ts` (Astro-Han/pawwork, PR `#287`), `makeReadLastCompletedAssistantText` intentionally scans the full child session message history (no `limit`) to find the latest completed assistant text part for `partial_result` on cancellation. Cancellation is a rare path so the extra read cost is acceptable; tool-heavy children can push the last stable assistant text far back. Do NOT suggest re-adding a fixed small limit (e.g., `limit: 5`) to this function.

Do NOT re-flag the absence of `Effect.fnUntraced` on `splitTurn` or other internal helpers in `compaction.ts` during upstream-sync PRs; flag it only in the dedicated convention-sweep PR.

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.
