Subject: [PATCH 01/58] feat(wizard): generalize into a reusable primitive
 (text steps, optional review, title)

render/wizard.ts was coupled to setup. Generalize it (its pure model + hardened
alt-screen/raw-mode driver stay):
- new `text` step kind: default/placeholder, secret masking, validate() that
  blocks confirm; char/erase in the pure reducer; caret + inline error render
- parameterized `title` (was hardcoded "tsforge setup")
- optional review screen (`review:false` applies on the last step's confirm)
- results now include `text` (+ `textValue` helper); overview shows text answers
- driver takes an options object {title, review, extra, out}; `b`/`q` are
  back/cancel except on a text field (where they're literal input)

Subject: [PATCH 02/58] refactor(setup,scaffold): call the generalized
 runWizard via its options object
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Both callers pass {title, extra} instead of positional args — setup keeps its
'tsforge setup' header; scaffold now gets a correct 'tsforge scaffold' header
(it previously inherited the hardcoded setup title). Behavior-preserving for setup.

+# Generic Wizard Primitive Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Generalize the existing `render/wizard.ts` into a reusable wizard primitive (parameterized title, a `text` step kind, an optional review screen) and refactor `/setup` onto it, so `/config` and "add a model" can be built as wizard flows later.
+
+**Architecture:** Keep the existing pure state model (`initWizard`/`reduceWizard`) and the interactive driver (`runWizard`, alt-screen + raw-mode + listener restore). Extend the type surface and reducer with a `text` step kind and character input, thread `title`/`review` options through render and driver, and make `/setup` a caller that passes its own title. No behavior change for setup.
+
+**Tech Stack:** TypeScript (strict), Bun test, Node `readline` keypress, Python `pty` for the real-terminal e2e.
+
+## Global Constraints
+
+- House rules (verbatim): no `as` casts; no `eslint-disable`; cyclomatic complexity ≤ 20; reuse shared walkers; explicit boolean conditions; no non-null `!`; `===`; `I`-prefixed interfaces.
+- `bun run validate` (check:bun + typecheck + lint + format:check + test + e2e:pty) must pass.
+- Do not touch the `runWizard` raw-mode ownership / listener stash-restore / EPIPE-guarded `finish` logic except to pass new options through.
+- Behavior-preserving for `/setup`: existing setup + wizard tests stay green.
+
+---
+
+### Task 1: `text` step kind + character input in the pure model
+
+**Files:**
+- Modify: `packages/core/src/render/wizard.types.ts`
+- Modify: `packages/core/src/render/wizard.ts` (state model region, lines ~19–229)
+- Test: `packages/core/tests/wizard.test.ts` (existing file — add cases)
+
+**Interfaces:**
+- Consumes: nothing new.
+- Produces: `IWizardStep.kind` now includes `"text"`; `IWizardStep` gains `placeholder?`, `default?`, `mask?`, `validate?`; `IWizardState` gains `text: Readonly<Record<string,string>>`; `IWizardAction` gains `"erase"` and the object form `{ readonly char: string }`; new helper `textValue(state, step): string`.
+
+- [ ] **Step 1: Write the failing test**
+
+Add to `packages/core/tests/wizard.test.ts`:
+
+```ts
+import { driveWizard, textValue } from "../src/render/wizard";
+import type { IWizardStep } from "../src/render/wizard.types";
+
+const textStep: IWizardStep = {
+  key: "baseUrl",
+  kind: "text",
+  title: "Base URL",
+  explanation: "The API root",
+  evidence: [],
+  options: [],
+  default: "http://localhost:8000/v1",
+};
+
+test("text step: default is used when nothing typed, confirm advances", () => {
+  const s = driveWizard([textStep], ["confirm"]);
+  expect(s.text.baseUrl).toBe("http://localhost:8000/v1");
+  expect(s.status).toBe("apply"); // single step, review defaults on → overview; confirm again applies
+});
+
+test("text step: typed characters replace the default; erase backspaces", () => {
+  const s = driveWizard(
+    [textStep],
+    [{ char: "a" }, { char: "b" }, { char: "c" }, "erase"]
+  );
+  expect(textValue(s, textStep)).toBe("ab");
+});
+```
+
+- [ ] **Step 2: Run test to verify it fails**
+
+Run: `bun test packages/core/tests/wizard.test.ts -t "text step"`
+Expected: FAIL — `textValue` is not exported / `kind: "text"` not assignable / `{char}` not an `IWizardAction`.
+
+- [ ] **Step 3: Extend the types**
+
+In `packages/core/src/render/wizard.types.ts`, replace the `IWizardStep` and `IWizardAction` and `IWizardState` definitions:
+
+```ts
+export interface IWizardStep {
+  readonly key: string;
+  readonly kind: "single" | "multi" | "text";
+  readonly title: string;
+  readonly explanation: string;
+  readonly evidence: readonly string[];
+  readonly options: readonly IWizardOption[];
+  /** Single-select: the preselected option index (the recommendation). */
+  readonly defaultIndex?: number;
+  /** Multi-select: option indices checked on entry. */
+  readonly defaultChecked?: readonly number[];
+  /** Text: prefilled value shown on entry (editable). */
+  readonly default?: string;
+  /** Text: hint shown when the field is empty. */
+  readonly placeholder?: string;
+  /** Text: render the value as bullets (secrets, e.g. an API key). */
+  readonly mask?: boolean;
+  /** Text: return an error message to block confirm, or null when valid. */
+  readonly validate?: (value: string) => string | null;
+}
+
+/** Normalized input action. `{ char }` is one typed character (text steps). */
+export type IWizardAction =
+  | "up"
+  | "down"
+  | "toggle"
+  | "confirm"
+  | "back"
+  | "cancel"
+  | "erase"
+  | { readonly char: string };
+
+export interface IWizardState {
+  readonly stepIndex: number;
+  readonly cursor: number;
+  readonly single: Readonly<Record<string, string>>;
+  readonly multi: Readonly<Record<string, readonly number[]>>;
+  readonly text: Readonly<Record<string, string>>;
+  readonly status: "active" | "apply" | "cancel";
+}
+```
+
+- [ ] **Step 4: Seed text on init/entry and handle char/erase/confirm in the reducer**
+
+In `packages/core/src/render/wizard.ts`:
+
+Update `initWizard` to seed text defaults and include `text` in the returned state:
+
+```ts
+export function initWizard(steps: readonly IWizardStep[]): IWizardState {
+  const multi: Record<string, readonly number[]> = {};
+  const text: Record<string, string> = {};
+
+  for (const s of steps) {
+    if (s.kind === "multi") {
+      multi[s.key] = (s.defaultChecked ?? []).filter(
+        (i) => i >= 0 && i < s.options.length
+      );
+    } else if (s.kind === "text") {
+      text[s.key] = s.default ?? "";
+    }
+  }
+
+  return {
+    stepIndex: 0,
+    cursor: steps[0]?.defaultIndex ?? 0,
+    single: {},
+    multi,
+    text,
+    status: "active",
+  };
+}
+```
+
+Add the text helper + edit reducers (place near `toggleCheck`):
+
+```ts
+/** The current value of a text step. */
+export function textValue(state: IWizardState, step: IWizardStep): string {
+  return state.text[step.key] ?? "";
+}
+
+function typeChar(
+  state: IWizardState,
+  step: IWizardStep,
+  ch: string
+): IWizardState {
+  if (step.kind !== "text") {
+    return state;
+  }
+
+  return {
+    ...state,
+    text: { ...state.text, [step.key]: `${state.text[step.key] ?? ""}${ch}` },
+  };
+}
+
+function eraseChar(state: IWizardState, step: IWizardStep): IWizardState {
+  if (step.kind !== "text") {
+    return state;
+  }
+
+  const current = state.text[step.key] ?? "";
+
+  return {
+    ...state,
+    text: { ...state.text, [step.key]: current.slice(0, -1) },
+  };
+}
+```
+
+Update `reduceStep` to route the new actions and block confirm on invalid text:
+
+```ts
+function reduceStep(
+  state: IWizardState,
+  action: IWizardAction,
+  step: IWizardStep,
+  steps: readonly IWizardStep[]
+): IWizardState {
+  if (typeof action === "object") {
+    return typeChar(state, step, action.char);
+  }
+
+  switch (action) {
+    case "up":
+      return {
+        ...state,
+        cursor: clampIndex(state.cursor - 1, step.options.length),
+      };
+    case "down":
+      return {
+        ...state,
+        cursor: clampIndex(state.cursor + 1, step.options.length),
+      };
+    case "toggle":
+      return step.kind === "multi" ? toggleCheck(state, step) : state;
+    case "erase":
+      return eraseChar(state, step);
+    case "confirm":
+      return step.kind === "text" &&
+        step.validate !== undefined &&
+        step.validate(state.text[step.key] ?? "") !== null
+        ? state
+        : confirmStep(state, step, steps);
+    case "back":
+      return goBack(state, steps);
+    default:
+      return state;
+  }
+}

+
+Update the `reduceWizard` top-level `cancel` guard (it currently checks `action === "cancel"` — that still works since object actions are never "cancel"). No change needed there beyond the object never matching the string cases.

+### Task 2: Parameterized title + optional review screen
+
+**Files:**
+- Modify: `packages/core/src/render/wizard.ts` (`reduceOverview`/`reduceWizard`, `renderStep`/`renderOverview`/`renderFrame`)
+- Test: `packages/core/tests/wizard.test.ts`
+
+**Interfaces:**
+- Consumes: Task 1 state shape.
+- Produces: `reduceWizard(state, action, steps, opts?: IWizardOpts)` and `driveWizard(steps, actions, opts?)` and `renderFrame(state, steps, color, extra?, title?)`; `IWizardOpts = { readonly review?: boolean }`. When `review === false`, confirming the last step yields `status:"apply"` directly (no overview).
+
+- [ ] **Step 1: Write the failing test**
+
+```ts
+test("review:false applies on the last step's confirm (no overview)", () => {
+  const s = driveWizard([textStep], ["confirm"], { review: false });
+  expect(s.status).toBe("apply");
+  expect(s.text.baseUrl).toBe("http://localhost:8000/v1");
+});
+
+test("renderFrame uses the supplied title", () => {
+  const frame = renderFrame(initWizard([textStep]), [textStep], false, "", "config");
+  expect(frame).toContain("config");
+  expect(frame).not.toContain("tsforge setup");
+});
+```
+
+(Add `renderFrame`, `initWizard` to the existing import from `../src/render/wizard`.)
+
+- [ ] **Step 2: Run to verify it fails**
+
+Run: `bun test packages/core/tests/wizard.test.ts -t "review:false"`
+Expected: FAIL — `driveWizard` takes 2 args / `renderFrame` has no title param / status becomes "active" (overview), not "apply".
+
+- [ ] **Step 3: Thread `IWizardOpts` through the reducer**
+
+In `packages/core/src/render/wizard.ts` add the type and update `confirmStep` to short-circuit to apply when review is off and this is the last step:
+
+```ts
+export interface IWizardOpts {
+  readonly review?: boolean;
+}
+
+function confirmStep(
+  state: IWizardState,
+  step: IWizardStep,
+  steps: readonly IWizardStep[],
+  opts: IWizardOpts
+): IWizardState {
+  const single =
+    step.kind === "single"
+      ? {
+          ...state.single,
+          [step.key]:
+            step.options[clampIndex(state.cursor, step.options.length)]
+              ?.value ?? "",
+        }
+      : state.single;
+  const nextIndex = state.stepIndex + 1;
+
+  // review off + last step → apply immediately, skipping the overview.
+  if (opts.review === false && nextIndex >= steps.length) {
+    return { ...state, single, status: "apply" };
+  }
+
+  const next = steps[nextIndex];
+
+  return {
+    ...state,
+    single,
+    stepIndex: nextIndex,
+    cursor: next === undefined ? 0 : cursorForStep(next, { ...state, single }),
+  };
+}
+```
+
+Thread `opts` through `reduceStep` and `reduceWizard` (default `{}`), and `driveWizard`:
+
+```ts
+export function reduceWizard(
+  state: IWizardState,
+  action: IWizardAction,
+  steps: readonly IWizardStep[],
+  opts: IWizardOpts = {}
+): IWizardState {
+  if (state.status !== "active") {
+    return state;
+  }
+  if (action === "cancel") {
+    return { ...state, status: "cancel" };
+  }
+  if (state.stepIndex >= steps.length) {
+    return reduceOverview(state, action, steps);
+  }
+  const step = steps[state.stepIndex];
+  if (step === undefined) {
+    return action === "confirm"
+      ? { ...state, stepIndex: state.stepIndex + 1 }
+      : state;
+  }
+  return reduceStep(state, action, step, steps, opts);
+}
+
+export function driveWizard(
+  steps: readonly IWizardStep[],
+  actions: readonly IWizardAction[],
+  opts: IWizardOpts = {}
+): IWizardState {
+  return actions.reduce(
+    (state, action) => reduceWizard(state, action, steps, opts),
+    initWizard(steps)
+  );
+}
+```
+
+Update `reduceStep`'s signature to accept + forward `opts` to `confirmStep` (only the confirm case changes: `return … confirmStep(state, step, steps, opts)`).
+
+- [ ] **Step 4: Parameterize the title in render**
+
+Replace the hardcoded `"tsforge setup"` in `renderStep` and `renderOverview` with a `title` param, and thread it through `renderFrame` (default `"tsforge setup"` so existing setup output is unchanged):
+
+```ts
+function renderStep(
+  step: IWizardStep,
+  state: IWizardState,
+  color: boolean,
+  total: number,
+  title: string
+): string {
+  // …unchanged body, except the first line:
+  //   paint(title, STYLE.brand, color),
+}
+
+function renderOverview(
+  steps: readonly IWizardStep[],
+  state: IWizardState,
+  color: boolean,
+  extra: string,
+  title: string
+): string {
+  // …unchanged, first line: paint(title, STYLE.brand, color),
+}
+
+export function renderFrame(
+  state: IWizardState,
+  steps: readonly IWizardStep[],
+  color: boolean,
+  extra = "",
+  title = "tsforge setup"
+): string {
+  if (state.stepIndex >= steps.length) {
+    return renderOverview(steps, state, color, extra, title);
+  }
+  const step = steps[state.stepIndex];
+  return step === undefined
+    ? ""
+    : renderStep(step, state, color, steps.length, title);
+}
+```
+
+- [ ] **Step 5: Run to verify it passes**
+
+Run: `bun test packages/core/tests/wizard.test.ts`
+Expected: PASS (new + existing wizard tests).
+
+- [ ] **Step 6: Commit**
+
+```bash

+
+### Task 3: Render text steps (value, caret, mask, validation error)
+
+**Files:**
+- Modify: `packages/core/src/render/wizard.ts` (`renderStep`, `hints`)
+- Test: `packages/core/tests/wizard.test.ts`
+
+**Interfaces:**
+- Consumes: Task 1 (`textValue`, `text` state), Task 2 (`renderFrame` title).
+- Produces: a text step renders its current value + a caret `▏`; masked steps render bullets `•`; an inline validation error line appears under the field when `validate` returns non-null.
+
+- [ ] **Step 1: Write the failing test**
+
+```ts
+const keyStep: IWizardStep = {
+  key: "apiKey",
+  kind: "text",
+  title: "API key",
+  explanation: "Secret",
+  evidence: [],
+  options: [],
+  mask: true,
+  validate: (v) => (v.length === 0 ? "required" : null),
+};
+
+test("text render: masks the value and shows a validation error when empty", () => {
+  const typed = driveWizard([keyStep], [{ char: "s" }, { char: "k" }]);
+  const frame = renderFrame(typed, [keyStep], false, "", "config");
+  expect(frame).toContain("••"); // masked, not "sk"
+  expect(frame).not.toContain("sk");
+
+  const empty = initWizard([keyStep]);
+  expect(renderFrame(empty, [keyStep], false, "", "config")).toContain("required");
+});
+```
+
+- [ ] **Step 2: Run to verify it fails**
+
+Run: `bun test packages/core/tests/wizard.test.ts -t "text render"`
+Expected: FAIL — text steps currently render option rows (empty) with no value/mask/error.
+
+- [ ] **Step 3: Add a text-field renderer**
+
+In `packages/core/src/render/wizard.ts`, add a text branch to `renderStep`. Insert before the `rows =` computation and branch on `step.kind === "text"`:
+
+```ts
+function textFieldRows(
+  step: IWizardStep,
+  state: IWizardState,
+  color: boolean
+): string[] {
+  const raw = textValue(state, step);
+  const shown =
+    raw.length === 0
+      ? paint(step.placeholder ?? "", STYLE.dim, color)
+      : step.mask === true
+        ? "•".repeat(raw.length)
+        : raw;
+  const field = `${shown}${paint("▏", STYLE.brand, color)}`;
+  const error =
+    step.validate === undefined ? null : step.validate(raw);
+  const errorLine =
+    error === null ? [] : ["", paint(error, STYLE.yellow, color)];
+
+  return [paint("Value", STYLE.bold, color), `  ${field}`, ...errorLine];
+}
+```
+
+In `renderStep`, produce the body per kind:
+
+```ts
+  const body =
+    step.kind === "text"
+      ? textFieldRows(step, state, color)
+      : [
+          paint("Choices", STYLE.bold, color),
+          ...(step.kind === "multi"
+            ? multiChoiceRows(step, state.cursor, state.multi[step.key] ?? [], color)
+            : singleChoiceRows(step, state.cursor, color)),
+          ...outcome,
+        ];
+```
+
+Then assemble with `...body` where `...rows, ...outcome` were. Guard `outcome` computation so it only runs for single (leave as-is; it already checks `step.kind === "single"`).
+
+Update `hints` for the text kind:
+
+```ts
+function hints(step: IWizardStep, color: boolean): string {
+  const parts =
+    step.kind === "text"
+      ? ["type to edit", "enter continue", "b back", "q cancel"]
+      : step.kind === "multi"
+        ? ["space toggle", "enter continue", "b back", "q cancel"]
+        : ["↑/↓ move", "enter select", "b back", "q cancel"];
+  return paint(parts.join("   "), STYLE.dim, color);
+}
+```
+

+
+### Task 4: Driver wires char/erase + passes title/review
+
+**Files:**
+- Modify: `packages/core/src/render/wizard.ts` (`actionFor`, `runWizard`)
+- Test: `packages/core/tests/wizard.test.ts` (extend `actionFor` decode test if present, else add)
+
+**Interfaces:**
+- Consumes: Tasks 1–3.
+- Produces: `actionFor` returns `{ char }` for a printable key, `"erase"` for backspace; `runWizard(steps, color, opts?)` where `opts: { title?: string; review?: boolean; extra?: (s) => string; out?: (s) => void }`.
+
+- [ ] **Step 1: Write the failing test**
+
+```ts
+import { actionFor } from "../src/render/wizard";
+
+test("actionFor: printable → char, backspace → erase", () => {
+  expect(actionFor("x", { name: "x" })).toEqual({ char: "x" });
+  expect(actionFor(undefined, { name: "backspace" })).toBe("erase");
+  expect(actionFor(undefined, { name: "up" })).toBe("up");
+});
+```
+
+- [ ] **Step 2: Run to verify it fails**
+
+Run: `bun test packages/core/tests/wizard.test.ts -t "actionFor: printable"`
+Expected: FAIL — `actionFor` returns `null` for `"x"` and has no `erase`.
+
+- [ ] **Step 3: Extend `actionFor`**
+
+In `packages/core/src/render/wizard.ts`, before the final `return null`, add backspace and printable handling (keep the existing arrow/enter/space/`b`/`q` mapping — but note: with text steps, `b`/`q`/space are literal characters, so printable handling must come AFTER the named-key switch yet the single-char `b`/`q` shortcuts now only apply to non-text steps; simplest correct rule: named control keys first, then backspace, then any single printable char becomes `{char}`; drop the `str === "b"/"q"/" "` string shortcuts in favor of named keys `backspace`/`space` and let `b`/`q` be typed text):
+
+```ts
+export function actionFor(
+  str: string | undefined,
+  key: IKeyInfo
+): IWizardAction | null {
+  if ((key.ctrl === true && key.name === "c") || key.name === "escape") {
+    return "cancel";
+  }
+  switch (key.name) {
+    case "up":
+      return "up";
+    case "down":
+      return "down";
+    case "space":
+      return "toggle";
+    case "backspace":
+      return "erase";
+    case "return":
+    case "enter":
+      return "confirm";
+    default:
+      break;
+  }
+  if (str !== undefined && str.length === 1 && str >= " ") {
+    return { char: str };
+  }
+  return null;
+}
+```
+
+NOTE: this removes the `b`/`q`/`space`-as-string back/cancel shortcuts. Back/cancel now come from named keys (Esc = cancel already; add left-arrow = back is out of scope). To preserve a non-text back/cancel without a Ctrl chord, the driver maps them per step kind — see Step 4.
+
+- [ ] **Step 4: Map `b`/`q` to back/cancel only on non-text steps in the driver**
+
+In `runWizard`'s `onKey`, before calling `actionFor`, special-case `b`/`q` when the active step is not a text step:
+
+```ts
+    const onKey = (str: string | undefined, key: IKeyInfo): void => {
+      try {
+        const step = steps[state.stepIndex];
+        const isText = step !== undefined && step.kind === "text";
+        let action = actionFor(str, key);
+        if (!isText && str === "b") {
+          action = "back";
+        } else if (!isText && str === "q") {
+          action = "cancel";
+        }
+        if (action === null) {
+          return;
+        }
+        state = reduceWizard(state, action, steps, { review: opts.review });
+        if (state.status !== "active") {
+          finish();
+        } else {
+          draw();
+        }
+      } catch {
+        state = cancelled;
+        finish();
+      }
+    };
+```
+
+Change the `runWizard` signature + internals to take an options object (default preserves current behavior):
+
+```ts
+export interface IRunWizardOpts {
+  readonly title?: string;
+  readonly review?: boolean;
+  readonly extra?: (state: IWizardState) => string;
+  readonly out?: (s: string) => void;
+}
+
+export function runWizard(
+  steps: readonly IWizardStep[],
+  color: boolean,
+  opts: IRunWizardOpts = {}
+): Promise<IWizardState> {
+  const out = opts.out ?? ((s: string) => process.stdout.write(s));
+  const extra = opts.extra ?? (() => "");
+  const title = opts.title ?? "tsforge setup";
+  // …existing body; `draw` uses renderFrame(state, steps, color, extra(state), title)
+}
+```
+
+- [ ] **Step 5: Run tests**

+### Task 5: Refactor `/setup` onto the generalized `runWizard`
+
+**Files:**
+- Modify: `packages/core/src/setup/run-setup.ts` (the `runWizard(...)` call, ~line 108)
+- Test: existing `packages/core/tests/*setup*`/`*wizard*` suites (no new test; behavior-preserving)
+
+**Interfaces:**
+- Consumes: Task 4 `runWizard(steps, color, opts)`.
+- Produces: no new surface; setup now passes `{ title: "tsforge setup", extra }` instead of positional `extra`.
+
+- [ ] **Step 1: Update the call site**
+
+In `packages/core/src/setup/run-setup.ts`, change the positional call to the options form. Find the existing:
+
+```ts
+const finalState = await runWizard(steps, color, extra);
+```
+
+Replace with:
+
+```ts
+const finalState = await runWizard(steps, color, { title: "tsforge setup", extra });
+```
+
+(If `out` was passed positionally, move it into the opts object too: `{ title: "tsforge setup", extra, out }`.)
+
+- [ ] **Step 2: Run the setup + wizard suites**
+
+Run: `bun test packages/core/tests/wizard.test.ts && bun test packages/core/tests/setup*.test.ts`
+Expected: PASS — output identical to before (title still "tsforge setup", review still on).
+
+- [ ] **Step 3: Real setup smoke (non-interactive path unaffected)**
+
+Run: `bun packages/core/src/cli.ts setup --yes --dir /tmp/wizard-smoke 2>&1 | head`
+Expected: writes/【proposes】conventions with no crash (the `--yes` path doesn't open the wizard but exercises the shared config write).
+

+# In-harness config UX — design
+
+## Context
+
+tsforge has accumulated a large configuration surface (~45 `TSFORGE_*` env vars,
+19 CLI flags, `tsforge.config.json`, `~/.tsforge/models.json`). Today you can only
+discover and change most of it by reading source or docs. That fails the core UX
+bet: **nobody reads docs for two hours — people explore a tool through its TUI.**
+
+The goal: anything a user might reasonably want to configure should be both
+**discoverable** and **changeable** from inside the harness. Docs stay aligned, but
+they are a fallback, not the primary interface. The TUI is the documentation.
+
+Non-goal: exposing eval-only / harness-internal knobs (A-B experiment flags, the
+gate-subprocess env bridge, RPC sandbox vars). Those are not "things a user wants."
+
+## Core idea: a self-describing settings registry
+
+One extensible registry is the single source of truth for user-facing config —
+the same pattern as the (already shipped) Shift+Tab mode registry. Each setting
+declares what it is, its current value, how to change it, and where it persists.
+
+```ts
+interface ISetting<T> {
+  id: string;              // stable key, e.g. "model.active"
+  group: string;           // "Model" | "Behavior" | "Tools" | "Conventions"
+  label: string;           // short name shown in the menu
+  describe: string;        // ONE line: what it does — this is the in-TUI "docs"
+  read(ctx): T;            // current value, shown next to the label
+  edit(ctx): Promise<T | null>;   // runs a menu/wizard flow; null = cancelled
+  persist(ctx, value: T): Promise<void>;  // write to the right store
+  applyLive?(ctx, value: T): void;        // hot-apply without restart, when possible
+}
+```
+
+Because each entry is self-describing, three things fall out of one definition:
+1. **`/config`** renders the registry as a browsable, grouped menu — you *see* every
+   setting, its one-line description, and its current value. Discovery = browsing.
+2. **Docs generation**: `flags.mdx` (the user-facing table) is generated from the
+   registry, so it can never drift from what the TUI shows.
+3. **Extensibility**: adding a setting is one registry entry — no new command, no
+   new doc edit, no menu wiring.
+
+## `/config` command
+
+- New slash command `/config` (registry entry in `cli/commands.ts` + one `case` in
+  the `command()` dispatcher — the standard pattern).
+- Opens a grouped, keyboard-navigable menu built on the existing interactive
+  primitives (`render/command-menu.ts` `pickCommand` for single-select; `render/
+  wizard.ts` `runWizard` for multi-field flows like "add a model"). Alt-screen +
+  raw-mode handling is already solved there and coexists with the status bar.
+- Flow: open → arrow to a setting (its `describe` + current value visible) → Enter
+  runs `edit()` → `persist()` writes the correct store → `applyLive()` reflects it
+  immediately → menu shows the new value.
+
+## Stores (persistence adapters)
+
+| Store | Backed by | Reuse |
+| --- | --- | --- |
+| Model registry | `~/.tsforge/models.json` | `loadModelsConfig` / `saveModelsConfig` / `setActiveModel` |
+| Project config | `tsforge.config.json` | `loadTsforgeConfig` / `writeSetupConfig` (atomic merge) |
+| Session | in-memory (this run) | `session.setMode` / `setGate` / `setScope` |
+
+`applyLive`: model → `provider.reconfigure()`; mode → `session.setMode`; gate/scope →
+session setters. Settings that can't hot-apply say so and note "next session".
+
+## v1 settings (the genuinely user-facing knobs)
+
+- **Model** (`Model` group): switch active model; **add a model** (baseUrl / model /
+  apiKey via a `runWizard` flow) → `saveModelsConfig` + live `reconfigure()`. Removes
+  hand-editing `models.json`.
+- **Behavior** (`tsforge.config.json`): default mode (`policy.mode`), gate command,
+  editable scope.
+- **Tools & features** (`Tools` group): web tools, TDD enforcement, script tool as
+  friendly on/off. **Requires new plumbing** — see below.
+- **Conventions**: interface naming, enums, test style — reuse the setup wizard's
+  step definitions so `/config` and `setup` share them.
+
+### Feature-toggle plumbing (needed for the Tools group)
+
+Today `TSFORGE_WEB` / `TSFORGE_TDD` / `TSFORGE_NO_SCRIPT` etc. are env-only with
+nothing persisted. To make them settable + sticky:
+- Add a `features` block to `tsforge.config.json` (`{ web?, tdd?, script? }`).
+- Change `config/flags.ts` to resolve **env → config → default** (env still wins as
+  the escape hatch, so eval/CI is unaffected).
+This is the one non-trivial code change; everything else is menu + persist wiring.
+
+## Doc alignment
+
+A small generator walks the registry and emits the user-facing rows of
+`reference/flags.mdx` (id, description, default, store). A test asserts the committed
+doc matches the generated output (same pattern as the existing `RULES.md` drift
+check in CI), so docs can't silently drift from the TUI.
+
+## Testing
+
+- **Unit**: the registry (each setting's read/persist round-trips against a temp
+  store); the menu reducer (pure, like the wizard reducer).
+- **Real-PTY e2e** (in the gate): open `/config`, switch the active model against the
+  stub server, assert it persisted to models.json AND hot-applied (status bar model
+  changes); toggle a feature and assert the `features` block was written.
+- **Doc-drift test**: generated `flags.mdx` rows == committed.
+
+## Rollout
+
+1. Registry + `/config` menu + Model and Behavior groups (no schema change).
+2. `features` block + `flags.ts` env→config→default + Tools group.
+3. Conventions group (reuse setup steps) + doc generator + drift test.
+4. Later: `setup` wizard renders first-run onboarding from the same registry (one
+   source of truth for both onboarding and live config).

+# Generic wizard primitive — design
+
+## Context
+
+tsforge needs a beautiful, reusable wizard so in-harness UX (the coming `/config`,
+"add a model", and the existing `/setup`) all render from **one** primitive instead
+of duplicating keypress/alt-screen/selection logic. See
+`2026-07-03-config-ux-design.md` — that feature consumes this one.
+
+`render/wizard.ts` already implements a solid wizard, but it is coupled to `setup`:
+a hardcoded "tsforge setup" header, an always-on Review/Apply overview, and only
+single/multi-select steps (no free-text). The work is to **generalize it in place**,
+not rewrite it — its pure state model and its hard-won interactive driver (alt-screen,
+safe raw-mode, listener stash/restore, EPIPE-guarded exit) stay.
+
+## Keep (already good)
+- Pure model: `initWizard` / `reduceWizard` / `driveWizard` — testable without a TTY.
+- Back-and-forth nav: `b` back, `enter` advance, `q`/Esc cancel, overview back.
+- `single` and `multi` step kinds with recommended tags, evidence, outcome, notes.
+- The `runWizard` driver: alt-screen, raw-mode ownership logic, listener restore,
+  exception-safe `finish`. Untouched.
+
+## Changes (what makes it generic + beautiful)
+
+### 1. Parameterize the title
+`renderStep`/`renderOverview` hardcode `"tsforge setup"`. Add a `title` to the wizard
+config (default `"tsforge"`); setup passes `"setup"`, config passes `"config"`, etc.
+
+### 2. New `text` step kind
+The blocker for "add a model" (baseUrl / model / apiKey are free text).
+`IWizardStep.kind` gains `"text"`, with:
+- `placeholder?` / `default?` — seed value shown when empty / prefilled.
+- `mask?: boolean` — render as bullets (apiKey / secrets).
+- `validate?(value): string | null` — inline error message, blocks `confirm` until valid.
+
+State: add `text: Readonly<Record<string, string>>` to `IWizardState`, plus a
+transient edit buffer for the active text step. Reducer gains character/backspace
+handling for text steps; the key→action decode gains `"char"` and `"erase"` actions
+(printable input + backspace) that only apply on a text step. All still pure.
+
+### 3. Optional review screen
+Add `review?: boolean` to the wizard config (default `true` for guided flows). When
+`false`, confirming the last step finishes with status `"apply"` directly — right for
+a quick single-pick ("switch model") where a Review page is friction.
+
+### 4. Results shape
+`runWizard` already returns `IWizardState`; callers read `state.single` / `checkedValues`.
+Add `state.text` and a `textValue(state, step)` helper so a caller gets every answer by
+`step.key`, regardless of kind.
+
+### 5. Beauty pass
+- Consistent header: `title` + `Step X of N · <step title>` + a rule.
+- Clear active-row highlight (existing `›` gutter + brand color), recommended tag,
+  multi checkboxes `◉/◯` (existing), and for `text` a visible caret + masked bullets.
+- A single, consistent key-hint footer per kind (e.g. text: `type   enter continue   b back   q cancel`).
+- Validation errors render inline under the field in the warn color.
+
+## Refactor `/setup` onto it
+`setup/wizard-flow.ts` already builds `IWizardStep[]` and `run-setup.ts` already calls
+`runWizard`. The only changes: pass `title: "setup"` and (unchanged) its `extra`
+config-preview for the overview. This turns setup into a *caller* of the generic
+primitive — the de-duplication the user asked for — with no behavior change.
+
+## Non-goals
+- Not folding `command-menu.ts` (the `/` palette) into the wizard now. It could later
+  be expressed as a 1-step single-select, but coupling it in adds risk for no v1 gain.
+- No new theming system — reuse the existing `STYLE` palette.
+
+## Testing
+- **Pure reducer** (extend existing wizard tests): `text` entry (type/erase/validate),
+  optional-review flow (last-step confirm → apply when `review:false`), title param,
+  results include `text`. `driveWizard([...actions])` asserts final state.
+- **Key→action decode** (`actionFor`): printable → `char`, backspace → `erase`,
+  existing arrows/enter/back/cancel unchanged.
+- **Existing setup wizard tests stay green** (the refactor is behavior-preserving).
+- **Real-PTY e2e** (new, in the gate): spawn a tiny harness that runs `runWizard` with
+  a mixed step set (single + text + multi), drive it over a real pty (arrow, type
+  chars, backspace, `b` back, `enter`), and assert the rendered frames + final
+  `{single, multi, text}` result. Verifies the primitive works in a real terminal —
+  not just the reducer.
+
+## Rollout
+1. Generalize `render/wizard.ts` (title, `text` kind, optional review, `text` results)
+   + beauty pass + unit tests.
+2. Refactor `/setup` onto it; confirm setup tests + a real setup run are unchanged.
+3. Real-PTY e2e for the wizard.
+Then the config-ux spec builds `/config` and add-model as flows on this base.

Subject: [PATCH 06/58] fix(wizard): type spaces in text fields; honest
 text-step hints (PR #66 review)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Gemini review:
- HIGH: space on a text step decoded to "toggle" (a no-op) — you couldn't type a
  space. On a text step, EVERY printable ASCII char (0x20–0x7e) is now literal
  input, incl. space/b/q. Bounded at 0x7e so DEL (backspace) still decodes as erase.
- MEDIUM: text-step hints falsely showed "b back / q cancel" (those are typed).
  Hints now read "type to edit · ← back · enter continue · esc cancel"; ← is a real
  back key for text steps (left-arrow is otherwise unused while editing).

Guards: reducer test (space types into a field), actionFor DEL boundary, and the
real-pty e2e now types a value WITH a space ("x y") to lock the regression.

Subject: [PATCH 07/58] feat(cli): /config settings menu (switch / add a model)
 on the generic wizard
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

First consumer of the generic wizard: an in-harness settings menu so users never
hand-edit ~/.tsforge/models.json.

- cli/config-menu.ts: settings surface built from wizard steps — buildConfigMenu
  (switch/add), buildModelPickStep, buildAddModelSteps (name/baseUrl/model/apiKey;
  apiKey masked + optional; required-field validation), draftToEntry + addModel
  (pure). Persists via saveModelsConfig/setActiveModel; hot-swaps the provider via
  an injected reconfigure. Mode / feature-toggle groups slot in later.
- cli.ts: /config → runConfigCommand, extracted to handleConfig for the complexity
  cap; suspends the REPL editor's stdin around the wizard via a repl-scoped
  editorControl (mirrors resizeEditor); applies the result live.
- commands.ts: /config in the registry.

Tests: config-menu pure builders/validators/addModel; a real-pty e2e
(scripts/e2e-config-pty.py, in the gate) drives the add-model flow end to end and
asserts models.json persisted + active + provider hot-swapped.

Subject: [PATCH 08/58] feat(cli): comprehensive /config settings hub + fix
 wizard quit-on-cancel
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Rebuild /config as a single owned-stdin menu loop (no nested overlays), which
fixes the reported bugs and makes it a real settings hub.

Bug fixed (reported): a REPL-launched wizard called stdin.pause() on exit —
because the editor owns stdin via a `data` listener (no keypress listeners), the
wizard wrongly thought it owned raw mode. pause() emptied the event loop and
QUIT tsforge on cancel/back/apply. Fix: runWizard gains `manageInput` (default
true); REPL callers (/config, and /setup from the editor) pass false so they
never seize/pause stdin. Also removes the 'b'-leaks-into-input class (no nesting
+ clear the editor buffer on resume).

/config is now a hub (cli/config-menu.ts) — one keypress session, grouped
settings, each with a one-line description + live value, applied immediately:
- Model: switch active (cycles models.json) + add a model (inline text fields,
  masked optional apiKey, validation) -> saveModelsConfig + live reconfigure
- Behavior: mode (plan/normal), gate command, editable scope (session)
- Tools: web / TDD / script toggles (env, live for subsequent turns)
Pure helpers unit-tested; the interactive loop covered by a REAL-REPL pty e2e
(open /config via the palette; cancel-doesn't-quit, live mode toggle, add-model
persist). Removed the obsolete standalone harness. Docs updated. validate green
(1858 pass; all three pty suites pass).

Subject: [PATCH 09/58] fix(config): one-line menu values + web tools on by
 default (interactive)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- The auto-detected gate command is a huge multi-line tsc+eslint+test string; it
  rendered verbatim and blew the whole /config menu layout out. Menu rows now clamp
  each value to one line (whitespace-collapsed, ellipsis) via oneLine().
- Web tools now default ON in the interactive REPL (an assistant that can't look
  things up is silly). Only a default — an explicit TSFORGE_WEB (incl. "0") wins,
  and one-shot/headless/eval never run repl() so they stay offline+deterministic.

Test: oneLine unit test (truncate + collapse newlines); validate green (1859 pass,
all pty suites).

Subject: [PATCH 10/58] feat(config): make /config comprehensive; delete ENV
 cruft
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

/config is now the single home for what a human actually configures, each
setting with its own visible one-line description (the config screen IS the
docs). Removed nonsensical toggles — nobody disables code navigation or git
context — those stay env-only for eval/CI.

- config-menu: per-setting descriptions rendered under every row; add Update
  check toggle; Web tools default-on (interactive) surfaced live.
- Delete experimental ENV flags + all consumers/tests: TSFORGE_LEGACY_FEEDBACK,
  TSFORGE_NO_ASTGREP, TSFORGE_FORCE_TOOLS, TSFORGE_SIMPLICITY, TSFORGE_CONTRACT.
- Graduate to always-on (flag deleted): hashline, TTSR, LSP write feedback.
- Remove the now-dead yield_status machinery (only the deleted forced-tools
  experiment advertised it): tool spec, dispatch stub, policy class, session
  resolveYieldCalls.
- Eval sweep dims trimmed to live flags (git/script/web).
- Docs: flags.mdx points feature toggles at /config; purge deleted flags across
  uplift/eval/greenfield/lsp/quality/web docs.

Verified: bun run validate green (typecheck+lint+format, 1842 tests, 3 pty
suites) + real iTerm2 GUI drive of /config.

 ## Git context
 
 On existing-code runs tsforge offers `git_context` — a read-only tool giving the model structured, token-bounded access to repo state, so it can scope a review or a fix to **what actually changed** instead of shelling out to raw `git`. Ops: `diff`, `changed_files`, `log` (incl. a line range's history), `blame`, and `show`. It wraps the `git` binary via an explicit argv (no shell), validates the `sha`, and rejects shell metacharacters / option injection in `ref`/`path`; output is char-capped (`maxChars` to raise it).
 
-Offered only when there is existing code to inspect (greenfield scratch builds have no history), and it survives `TSFORGE_NO_LSP_TOOLS` since it is not an LSP tool. Being read-only, it is available in [plan mode](/cli/plan-mode/) too.

Subject: [PATCH 11/58] fix(config): stop double-typed text in /config; trim to
 human settings

Fixes the double-typed text when entering values in /config (e.g. Add a model).
The palette launches /config via a fire-and-forget runLine then resume()s the
editor in its `finally`, re-activating it UNDERNEATH the overlay so every key was
echoed into the editor's pinned input row on top of the overlay's own render.
Add an `inert` input-gate to the editor that resume() does NOT clear; the /config
overlay sets it, so the stray resume can't re-activate the editor. Regression
tests in the real-PTY e2e: typed text renders once, and the editor works again
after /config closes.

Also trims /config to only genuine human choices:
- Remove Script tool + Update check toggles (eval/kill-switch knobs, not settings).
- Update check now ALWAYS runs (interactive, non-CI; respects NO_UPDATE_NOTIFIER);
  TSFORGE_NO_UPDATE_CHECK deleted. TSFORGE_NO_SCRIPT kept as an env kill-switch.
- e2e scripts switched from TSFORGE_NO_UPDATE_CHECK to NO_UPDATE_NOTIFIER offline.
- Docs updated: /config = model, mode, gate, scope, web, TDD; eval/CI-only knobs
  (NO_LSP_TOOLS/NO_GIT_TOOL/NO_SCRIPT) documented separately.

Verified: bun run validate green (typecheck+lint+format, tests, 3 pty suites) +
isolated pty repro (marker renders 1x, was 2x).

Subject: [PATCH 12/58] docs: fix staleness found in a full page-by-page source
 cross-reference
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Audited all 43 doc pages against the current source. Fixes:
- plan-mode / interactive: `--plan` accurately described (forces plan for an
  interactive session, overriding a repo's autonomous policy.mode; ignored by
  one-shot/headless) — was overstated/ambiguous.
- model-agent: add the `script` tool (programmatic tool calling) to the tool table.
- spec-runner / commands: eval sweep examples used the removed `ttsr,hashline`
  dimensions → live dims (`git`/`script`).
- validation: web-build turn cap 180 → 400 (loop.constants.ts webMaxTurns).
- rule-packs: `generic-ts` is an always-on pack (core TS safety), not a
  "detection label only" — moved into the always-on table.
- flags: document TSFORGE_BOOT_URL/TIMEOUT defaults (http://localhost:3000/, 15000ms).
- roadmap: "shipped through 0.18" → 0.27; Road-to-1.0 sweep example uses live dims.

30+ pages verified clean. Docs build green (46 pages).

Subject: [PATCH 13/58] docs(spec): in-harness capability browser (feature
 discoverability)

Design for making tsforge's capabilities discoverable in-session: /help becomes
an actionable capability browser over a self-describing registry; scaffold
(boringstack/astro/vite) + recipes brought into the REPL; an anti-drift test that
fails if a command or model tool ships without a discovery home.

+# In-harness capability browser (feature discoverability)
+
+**Status:** design, awaiting review
+**Date:** 2026-07-03
+**Branch (proposed):** `feat/capability-browser`
+
+## Problem
+
+tsforge has accumulated many capabilities that the harness never advertises, so
+users — including the author — forget they exist:
+
+- **Whole features live outside the interactive surface.** `tsforge scaffold`
+  (greenfield wizard → **boringstack** full stack or **astro** static site) and
+  `tsforge run <recipe>` (declarative recipes) are shell subcommands only. A user
+  in the REPL gets no hint they exist, and the astro-vs-boringstack choice is
+  invisible.
+- **Powerful capabilities run invisibly.** scout, `git_context`, web research, the
+  `script` tool, memory learning, TTSR, write-diagnostics are all active but the
+  user never learns them or sees them fire.
+- **Options within a feature are hidden.** e.g. archetype selection during scaffold.
+
+The 17 slash commands ARE listed (`/help` text + the `/` palette). The gap is the
+three classes above.
+
+Root cause: features have been added without any obligation to give them a
+discovery home. Docs drift; the TUI never learns about the feature at all.
+
+## Goals
+
+1. A **pull-based, in-session capability browser** — the user opens it and browses
+   everything the harness can do, grouped, each with a one-line description.
+2. **Actionable:** selecting a command runs it (or prefills its args); selecting a
+   wizard (scaffold) opens it **in the REPL**; selecting a passive capability shows
+   a short explainer.
+3. **Bring the scaffold flow into the session** — archetype pick
+   (boringstack / astro / vite) + config, driven in-REPL, not shell-only.
+4. **Make it structurally impossible to ship an undiscoverable feature** via an
+   anti-drift test over a single capability registry.
+
+## Non-goals (deferred to later specs)
+
+- Proactive/contextual surfacing (empty-dir → "scaffold?"). Separate spec.
+- "Make the invisible visible" run-time annotations (scout fired, memory recalled).
+- First-run onboarding tour.
+- Auto-generating a docs page from the registry (nice follow-up; the drift test is
+  the priority here).
+
+## Design
+
+### 1. Capability registry — single source of truth
+
+A pure, injected registry mirroring the existing `ISetting` registry
+(`src/cli/config-menu.ts`) and mode registry (`src/cli/modes.ts`).
+
+```ts
+// src/cli/capabilities.ts
+export type CapabilityKind = "command" | "wizard" | "passive";
+
+export interface ICapability {
+  readonly id: string;         // stable slug, e.g. "scaffold", "map", "tool.scout"
+  readonly group: string;      // display group (see §2)
+  readonly label: string;      // short name shown in the row
+  readonly describe: string;   // one-line in-TUI docs (REQUIRED, non-empty)
+  readonly kind: CapabilityKind;
+  /** Longer explainer shown when a `passive` row is selected (what it does + when
+   *  it fires). Optional for command/wizard rows. */
+  readonly detail?: string;
+  /** How the browser activates this row. For "command": the slash command to run
+   *  or prefill. For "wizard": an opener key the host maps to a wizard launcher.
+   *  For "passive": undefined (selection shows `detail`). */
+  readonly invoke?:
+    | { readonly type: "run"; readonly command: string }        // run immediately
+    | { readonly type: "prefill"; readonly command: string }    // e.g. "/gate "
+    | { readonly type: "wizard"; readonly opener: string };     // e.g. "scaffold"
+}
+
+export function buildCapabilities(deps: ICapabilityDeps): ICapability[];
+```
+
+`buildCapabilities` is pure and unit-testable (no I/O); the host injects the
+openers/runners via `ICapabilityDeps` (same dependency-injection style as
+`IConfigDeps`).
+
+### 2. `/help` becomes the browser
+
+`/help` stops printing static text and renders the grouped, actionable browser,
+**reusing the `/config` owned-stdin menu driver** (`runConfigMenu`'s pattern in
+`src/cli/config-menu.ts`): grouped rows, per-row dim `describe`, ↑/↓ nav, Enter,
+Esc, and the editor `inert` gate added for `/config`. We extract the shared driver
+so both `/config` and `/help` use it (no copy-paste).
+
+Groups and rows (each row = an `ICapability`):
+
+- **Build something new** — Scaffold a project *(wizard)* · Run a recipe *(wizard —
+  opens an in-REPL recipe picker; there is no `/run` slash command today, recipes
+  are the shell `tsforge run`)*
+- **Understand your code** — Map workspace (`/map`) · Review changes (`/review`)
+- **Steer the session** — Plan (`/plan`) · Gate (`/gate`) · Scope (`/files`) ·
+  Model (`/model`) · Settings (`/config`) · Conventions (`/setup`)
+- **Session & cost** — Sessions · Compact · Clear · Cost · Metrics · Trace · Memory
+- **The model's tools (always on)** — Scout · git context · web research · script ·
+  TTSR · write diagnostics · memory learning *(all `passive` — Enter shows `detail`)*
+
+Selection behavior by kind:
+- `command` + `invoke.run` → close the browser, run the slash command via the
+  existing dispatch (`runLine`/`command`).
+- `command` + `invoke.prefill` → close, prefill the input row (reuse the palette's
+  `takesArg` prefill path) so the user types the argument.
+- `wizard` → close the browser, open the wizard in-REPL (see §3).
+- `passive` → render the `detail` explainer in place (a sub-view; Esc returns to the
+  list). Nothing to run.
+
+### 3. Scaffold wizard in the REPL
+
+Selecting "Scaffold a project" opens a wizard **in-session** (not the shell
+subcommand), reusing `src/scaffold` + the generic wizard (`src/render/wizard.ts`),
+the same way `/setup` runs its wizard in-REPL:
+
+1. **Archetype step** — single-select: `boringstack` (full Bun+Elysia+Drizzle+Vite/
+   React), `astro` (static site), `vite` (React web skeleton, today's `--web`).
+2. **Config step(s)** — the existing scaffold config surface (manifest-driven for
+   boringstack/astro; `scaffold.types.ts` `IArchetype`/manifest), collected via the
+   generic wizard's text/single/multi steps.
+3. On finish, run the existing scaffold path (`src/scaffold/clone.ts` +
+   configure) exactly as the shell subcommand does, then hand back to the REPL.
+
+Wizards launched from the REPL must pass `manageInput: false` and run under the
+`inert` editor gate (both already exist) so they don't fight the editor for stdin.
+
+### 4. `/` palette stays the fast runner
+
+Unchanged as the fuzzy quick-runner for known commands. Optionally add a scaffold
+and a recipe launcher entry so power users can quick-launch them; `/help` remains
+the place to *discover*.
+
+### 5. Anti-drift test (the keystone)
+
+A unit test that fails when a feature ships without a discovery home:
+
+- Every entry in `COMMAND_SPECS` (`src/cli/commands.ts`) has a matching
+  `ICapability` (by the command name).
+- Every value in `TOOL_NAME` (`src/agent/agent.constants.ts`) has a matching
+  `passive` (or otherwise-classified) `ICapability`.
+- Every `ICapability.describe` is non-empty; every non-passive has a valid `invoke`.
+- The scaffold archetypes in `scaffold.types.ts` (`IArchetype`) are all reachable
+  from the scaffold wizard's archetype step.
+
+This is what prevents the discoverability rot from recurring.
+
+## Architecture / reuse (no new frameworks)
+
+- **Driver:** extract the owned-stdin grouped-menu loop from `config-menu.ts`
+  (`runConfigMenu`) into a shared `render/owned-menu.ts` (or keep in place and
+  parameterize) used by both `/config` and `/help`. Same key handling, `inert`
+  gate, alt-screen, per-row `describe`.
+- **Wizard:** `src/render/wizard.ts` (`runWizard`, `manageInput`) — already used by
+  `/setup`.
+- **Scaffold:** `src/scaffold/*` — already exists; we add an in-REPL launcher.
+- **Registry:** new `src/cli/capabilities.ts`, injected like `IConfigDeps`.
+
+## Testing
+
+1. **Unit — registry completeness / anti-drift** (§5). The keystone; ranks first.
+2. **Unit — `buildCapabilities`** against fake deps: every capability has group/
+   label/non-empty describe/valid kind+invoke; passive rows carry `detail`.
+3. **Real-PTY e2e** (`scripts/e2e-*-pty.py`, the definition-of-done per house
+   practice): open `/help`, assert groups + per-row descriptions render; select a
+   passive row → explainer shows; select a command → it runs; select "Scaffold" →
+   the archetype wizard opens (boringstack/astro/vite visible); Esc closes without
+   quitting; the editor works again afterward (inert gate cleared) and its input is
+   not doubled.
+
+## Rollout
+
+Single PR on `feat/capability-browser`. `bun run validate` green (typecheck + lint +
+format + unit + all PTY suites). Update docs: `cli/interactive.mdx` (/help is now a
+browser), a short note in the relevant pages that scaffold/recipes are reachable
+from `/help`.
+
+## Open questions
+
+- Recipe row: open an in-REPL recipe picker (reuse the menu driver over the named
+  recipe set), then run the chosen recipe via the existing `tsforge run` path.
+  Whether to also add a `/run <name>` slash command is optional and low-risk —
+  resolve during implementation.

+# Capability Browser Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Make every tsforge capability discoverable in-session — `/help` becomes an actionable, grouped capability browser over a self-describing registry, with the scaffold (boringstack/astro/vite) and recipe flows brought into the REPL, guarded by an anti-drift test.
+
+**Architecture:** A pure `ICapability[]` registry (mirroring the existing `ISetting`/mode registries) is the single source of truth. A generic owned-stdin grouped-menu driver — extracted from the proven `/config` menu — renders both `/config` and the new capability browser. Selecting a row runs a command, opens an in-REPL wizard (scaffold/recipe), or shows a passive-capability explainer. An anti-drift unit test fails if any slash command or model tool ships without a registry entry.
+
+**Tech Stack:** TypeScript (strict), Bun runtime, `node:readline` keypress loop, existing `src/render/wizard.ts` generic wizard, `src/scaffold/*`, Python `pty.fork` e2e harness.
+
+## Global Constraints
+
+- House rules (gate-enforced): no `as` casts, no `eslint-disable`, cyclomatic complexity ≤ 20, no non-null `!`, use `===`, explicit booleans, `I`-prefixed interfaces, prettier + `@stylistic/padding-line-between-statements` (blank line between statement kinds), `@typescript-eslint/no-floating-promises` (prefix fire-and-forget with `void`), `no-confusing-void-expression`, `prefer-optional-chain`, `no-dynamic-delete` (use `Reflect.deleteProperty`).
+- Definition of done for any TUI/CLI change: a **real-terminal PTY e2e** asserting on the rendered buffer — not just unit tests.
+- Reuse, don't re-roll: the generic wizard (`runWizard`, `manageInput`), the owned-stdin menu driver, `src/scaffold` functions, `loadRecipes`.
+- Branch: `feat/capability-browser` (already created; the spec commit `ddd0daa` is on it).
+- `bun run validate` (typecheck + lint + format + unit + all 3 PTY suites) must be green before "done".
+
+## File Structure
+
+- Create `packages/core/src/cli/capabilities.ts` — the `ICapability` registry + `buildCapabilities(deps)` (pure).
+- Create `packages/core/tests/capabilities.test.ts` — registry unit + anti-drift tests.
+- Create `packages/core/src/render/owned-menu.ts` — generic owned-stdin grouped-menu driver extracted from `config-menu.ts`.
+- Modify `packages/core/src/cli/config-menu.ts` — migrate `runConfigMenu` onto `owned-menu.ts` (behavior unchanged).
+- Create `packages/core/src/cli/capability-menu.ts` — `runCapabilityMenu(deps)` (the browser) + passive explainer sub-view.
+- Create `packages/core/tests/capability-menu.test.ts` — render + selection unit tests.
+- Modify `packages/core/src/cli.ts` — `/help` opens the browser on a TTY; add `openScaffold`/`openRecipe` deps.
+- Create `packages/core/src/cli/repl-scaffold.ts` — `openScaffoldInRepl(deps)` in-REPL scaffold launcher.
+- Create `packages/core/src/cli/repl-recipe.ts` — `openRecipePicker(deps)` in-REPL recipe launcher.
+- Create `scripts/e2e-help-browser-pty.py` — real-terminal e2e; wire into `package.json` `e2e:pty`.
+- Modify `apps/docs/src/content/docs/cli/interactive.mdx` — document `/help` as a browser.

+
+### Task 1: Capability registry + anti-drift test
+
+**Files:**
+- Create: `packages/core/src/cli/capabilities.ts`
+- Test: `packages/core/tests/capabilities.test.ts`
+
+**Interfaces:**
+- Consumes: `COMMANDS`, `takesArg` from `../cli/commands`; `TOOL_NAME` from `../agent`.
+- Produces:
+  ```ts
+  export type CapabilityKind = "command" | "wizard" | "passive";
+  export type CapabilityInvoke =
+    | { readonly type: "run"; readonly command: string }
+    | { readonly type: "prefill"; readonly command: string }
+    | { readonly type: "wizard"; readonly opener: "scaffold" | "recipe" };
+  export interface ICapability {
+    readonly id: string;
+    readonly group: string;
+    readonly label: string;
+    readonly describe: string;
+    readonly kind: CapabilityKind;
+    readonly detail?: string;
+    readonly invoke?: CapabilityInvoke;
+  }
+  export interface ICapabilityDeps { readonly hasRecipes: boolean; }
+  export function buildCapabilities(deps: ICapabilityDeps): ICapability[];
+  export function capabilityCommandNames(caps: readonly ICapability[]): string[];
+  ```
+
+- [ ] **Step 1: Write the failing tests**
+
+```ts
+// packages/core/tests/capabilities.test.ts
+import { test, expect } from "bun:test";
+import { buildCapabilities } from "../src/cli/capabilities";
+import { COMMANDS } from "../src/cli/commands";
+import { TOOL_NAME } from "../src/agent";
+
+const deps = { hasRecipes: true };
+
+test("every capability has group, label, non-empty describe, valid kind", () => {
+  for (const c of buildCapabilities(deps)) {
+    expect(c.group.length).toBeGreaterThan(0);
+    expect(c.label.length).toBeGreaterThan(0);
+    expect(c.describe.length).toBeGreaterThan(0);
+    expect(["command", "wizard", "passive"]).toContain(c.kind);
+  }
+});
+
+test("command/wizard capabilities carry an invoke; passive carry detail", () => {
+  for (const c of buildCapabilities(deps)) {
+    if (c.kind === "passive") {
+      expect((c.detail ?? "").length).toBeGreaterThan(0);
+    } else {
+      expect(c.invoke).toBeDefined();
+    }
+  }
+});
+
+// ── the keystone: anti-drift ────────────────────────────────────────────────
+test("ANTI-DRIFT: every slash command has a discovery home", () => {
+  const caps = buildCapabilities(deps);
+  const covered = new Set(
+    caps
+      .filter((c) => c.invoke?.type === "run" || c.invoke?.type === "prefill")
+      .map((c) => (c.invoke?.type === "run" || c.invoke?.type === "prefill" ? c.invoke.command : "")),
+  );
+  // Commands intentionally excluded from the browser (they ARE the browser / trivial).
+  const exempt = new Set(["/help", "/exit"]);
+
+  for (const spec of COMMANDS) {
+    if (exempt.has(spec.name)) {
+      continue;
+    }
+
+    expect(covered.has(spec.name)).toBe(true);
+  }
+});
+
+test("ANTI-DRIFT: every model tool has a discovery home", () => {

+      .filter((c) => c.kind === "passive")

+  expect(buildCapabilities({ hasRecipes: false }).some((c) => c.id === "recipe")).toBe(false);
+});
+```
+
+- [ ] **Step 2: Run the tests to verify they fail**
+
+Run: `bun test packages/core/tests/capabilities.test.ts`
+Expected: FAIL — `Cannot find module '../src/cli/capabilities'`.
+
+- [ ] **Step 3: Implement `buildCapabilities`**
+
+Author `packages/core/src/cli/capabilities.ts`. Build the list from three sources so the anti-drift tests pass:
+1. **Command rows** — one per `COMMANDS` entry except `/help`, `/exit`. `kind:"command"`, `invoke:{ type: takesArg(spec) ? "prefill" : "run", command: spec.name }`, `describe: spec.summary`, grouped per §2 of the spec (Build / Understand / Steer / Session). Map each command name to its group via a small `Record<string,string>`; any unmapped command falls in "Session & cost" (keeps the anti-drift test green if a command is added).
+2. **Wizard rows** — `{ id:"scaffold", group:"Build something new", label:"Scaffold a project", describe:"Stand up a new project — boringstack (full stack), astro (static site), or vite (web).", kind:"wizard", invoke:{type:"wizard",opener:"scaffold"} }`; and, when `deps.hasRecipes`, `{ id:"recipe", group:"Build something new", label:"Run a recipe", describe:"Run a saved build+gate flow from .tsforge/recipes.", kind:"wizard", invoke:{type:"wizard",opener:"recipe"} }`.
+3. **Passive rows** — one per model tool that runs invisibly, id `tool.<name>`, `kind:"passive"`, group `"The model's tools (always on)"`, each with a non-empty `detail`. Cover at least: `git_context`, `web_fetch`/`web_search` (one "web research" row is not enough for the tool-level anti-drift test — give each surfaced tool its own `tool.<name>` id OR widen the exempt set; simplest: one passive row per non-exempt tool name). Use a `Record<toolName, {label,describe,detail}>` so each has real copy.
+
+`capabilityCommandNames` returns the `command`/`prefill` command strings (used by tests + wiring).
+
+- [ ] **Step 4: Run the tests to verify they pass**
+
+Run: `bun test packages/core/tests/capabilities.test.ts`
+Expected: PASS (all 5 tests).
+
+- [ ] **Step 5: Typecheck, lint, commit**
+
+```bash
+bun run typecheck && bun x eslint packages/core/src/cli/capabilities.ts packages/core/tests/capabilities.test.ts
+git add packages/core/src/cli/capabilities.ts packages/core/tests/capabilities.test.ts
+git commit --no-gpg-sign -m "feat(cli): capability registry + anti-drift test"
+```
+
+---
+
+### Task 2: Extract the generic owned-stdin menu driver
+
+Extract the menu loop from `config-menu.ts` (`runConfigMenu`) into a reusable driver so `/config` and `/help` share one battle-tested implementation. The existing config unit tests + `scripts/e2e-config-repl-pty.py` (12/12) are the safety net — they must stay green.
+
+**Files:**
+- Create: `packages/core/src/render/owned-menu.ts`
+- Modify: `packages/core/src/cli/config-menu.ts`
+- Test: existing `packages/core/tests/config-menu.test.ts` + `scripts/e2e-config-repl-pty.py` (unchanged, must pass)
+
+**Interfaces:**
+- Produces:
+  ```ts
+  export interface IMenuRow { readonly group: string; readonly label: string;
+    readonly describe: string; readonly value?: string; }
+  export interface IOwnedMenuDeps {
+    readonly color: boolean;
+    readonly title: string;            // e.g. "tsforge config" / "tsforge — what can I do?"
+    readonly subtitle: string;         // e.g. "Settings · change anything here"
+    readonly footer: string;           // e.g. "↑/↓ move   enter change   esc done"
+    readonly suspend: () => void;
+    readonly resume: () => void;
+    readonly rows: () => readonly IMenuRow[];   // re-read after each activation (live values)
+    readonly onSelect: (index: number) => void | Promise<void>;
+    readonly onExit?: () => void;      // optional: draw an explainer sub-view yourself
+  }
+  export function runOwnedMenu(deps: IOwnedMenuDeps): Promise<void>;
+  ```
+- The driver owns: alt-screen enter/exit, `emitKeypressEvents`, keypress stash/restore, the `inert` editor-gate handshake via `suspend`/`resume` (host wires `editorControl.setInputInert`), ↑/↓ nav with `clampIndex`, Enter → `onSelect(cursor)` then redraw, Esc → resolve. Rendering: group headers + per-row `label · value` + dim `describe` line (verbatim from the current `renderMenu`), truncating values with the existing `oneLine`.
+
+- [ ] **Step 1: Extract the driver (no behavior change)**
+
+Move the `renderMenu`/keypress-loop internals of `runConfigMenu` into `runOwnedMenu`. `renderMenu` becomes a pure function over `IMenuRow[]` + cursor + color (keep exporting a thin `renderMenu` from `owned-menu.ts` for tests). Keep `oneLine`, `clampIndex` imports.
+
+- [ ] **Step 2: Migrate `runConfigMenu` onto the driver**
+
+Rewrite `runConfigMenu(deps)` to build `IMenuRow[]` from `buildSettings(deps)` (label + `s.read()` value + `s.describe`), pass `onSelect` = the existing setting activate/edit logic, and delegate the loop to `runOwnedMenu`. The text-field edit sub-view stays in `config-menu.ts` (config-specific), invoked from `onSelect`.
+
+- [ ] **Step 3: Run the config safety net**
+
+Run: `bun test packages/core/tests/config-menu.test.ts` → PASS.
+Run: `python3 scripts/e2e-config-repl-pty.py` → `15/15 — ALL PASS` (descriptions render, toggles flip, double-type stays fixed, editor works after).
+
+- [ ] **Step 4: Typecheck, lint, commit**
+
+```bash
+bun run typecheck && bun x eslint packages/core/src/render/owned-menu.ts packages/core/src/cli/config-menu.ts
+git add packages/core/src/render/owned-menu.ts packages/core/src/cli/config-menu.ts
+git commit --no-gpg-sign -m "refactor(render): extract generic owned-stdin menu driver; /config uses it"
+```

+### Task 3: The capability browser (`runCapabilityMenu`)
+
+**Files:**
+- Create: `packages/core/src/cli/capability-menu.ts`
+- Test: `packages/core/tests/capability-menu.test.ts`
+
+**Interfaces:**
+- Consumes: `buildCapabilities`, `ICapability` from `./capabilities`; `runOwnedMenu`, `renderMenu`, `IMenuRow` from `../render/owned-menu`.
+- Produces:
+  ```ts
+  export interface ICapabilityMenuDeps {
+    readonly color: boolean;
+    readonly hasRecipes: boolean;
+    readonly suspend: () => void;
+    readonly resume: () => void;
+    readonly runCommand: (command: string) => void;   // "run" → dispatch a slash command
+    readonly prefill: (command: string) => void;      // "prefill" → put "<cmd> " in the input
+    readonly openWizard: (opener: "scaffold" | "recipe") => Promise<void>;
+    readonly showDetail: (cap: ICapability) => Promise<void>; // passive explainer sub-view
+  }
+  export function capabilityRows(caps: readonly ICapability[]): IMenuRow[];
+  export function runCapabilityMenu(deps: ICapabilityMenuDeps): Promise<void>;
+  ```
+
+- [ ] **Step 1: Write the failing tests**
+
+```ts
+// packages/core/tests/capability-menu.test.ts
+import { test, expect } from "bun:test";
+import { capabilityRows } from "../src/cli/capability-menu";
+import { buildCapabilities } from "../src/cli/capabilities";
+import { renderMenu } from "../src/render/owned-menu";
+
+test("capabilityRows preserves group + label + describe for every capability", () => {
+  const caps = buildCapabilities({ hasRecipes: true });
+  const rows = capabilityRows(caps);
+
+  expect(rows.length).toBe(caps.length);
+  for (let i = 0; i < caps.length; i++) {
+    expect(rows[i]?.group).toBe(caps[i]?.group);
+    expect(rows[i]?.label).toBe(caps[i]?.label);
+    expect(rows[i]?.describe).toBe(caps[i]?.describe);
+  }
+});
+
+test("rendered browser shows every capability's description (screen IS the docs)", () => {
+  const caps = buildCapabilities({ hasRecipes: true });
+  const screen = renderMenu(capabilityRows(caps), 0, false);
+
+  for (const c of caps) {
+    expect(screen).toContain(c.describe);
+  }
+});
+```
+
+- [ ] **Step 2: Run to verify failure**
+
+Run: `bun test packages/core/tests/capability-menu.test.ts`
+Expected: FAIL — module not found.
+
+- [ ] **Step 3: Implement `capabilityRows` + `runCapabilityMenu`**
+
+`capabilityRows` maps each `ICapability` → `{ group, label, describe }` (no `value` — the browser has no live values). `runCapabilityMenu` builds caps via `buildCapabilities({hasRecipes})`, calls `runOwnedMenu` with title `"tsforge — what can I do?"`, footer `"↑/↓ move   enter run/open   esc close"`, and `onSelect(i)` that dispatches by the capability's `kind`/`invoke`:
+- `run` → `deps.runCommand(cmd)` then the menu resolves (close).
+- `prefill` → `deps.prefill(cmd)` then close.
+- `wizard` → `await deps.openWizard(opener)` (menu closes; wizard owns the screen).
+- `passive` → `await deps.showDetail(cap)` (sub-view; returns to the list — implement as `onSelect` redrawing after the detail promise, keeping the menu open).
+
+To keep the list open after a passive explainer but close after an action, model `onSelect` to return, and have the passive branch NOT resolve the menu (the driver redraws), while action branches call a provided `close()` — expose `close` via an extra `runOwnedMenu` affordance OR implement the browser's own thin loop reusing `renderMenu`. Prefer: give `IOwnedMenuDeps.onSelect` a `{ close: () => void }` argument so a row can choose to close or stay.
+
+- [ ] **Step 4: Run tests to verify pass**
+
+Run: `bun test packages/core/tests/capability-menu.test.ts`
+Expected: PASS.
+
+- [ ] **Step 5: Typecheck, lint, commit**
+
+```bash
+bun run typecheck && bun x eslint packages/core/src/cli/capability-menu.ts packages/core/tests/capability-menu.test.ts

+### Task 4: In-REPL scaffold launcher
+
+**Files:**
+- Create: `packages/core/src/cli/repl-scaffold.ts`
+- Test: `packages/core/tests/repl-scaffold.test.ts`
+
+**Interfaces:**
+- Consumes: `buildScaffoldSteps`, `stateToAnswers`, `answersToPlan`, `runScaffold`, `loadBundledManifest`, `realFs`, `realRunner`, `realPoller`, `IArchetype` from `../scaffold`; `runWizard` from `../render/wizard`.
+- Produces:
+  ```ts
+  export interface IReplScaffoldDeps {
+    readonly suspend: () => void; readonly resume: () => void;
+    readonly out: (s: string) => void;
+  }
+  export function archetypeStep(): IWizardStep; // single-select: boringstack/astro/vite
+  export function openScaffoldInRepl(deps: IReplScaffoldDeps): Promise<void>;
+  ```
+
+- [ ] **Step 1: Write the failing test (pure step builder)**
+
+```ts
+// packages/core/tests/repl-scaffold.test.ts
+import { test, expect } from "bun:test";
+import { archetypeStep } from "../src/cli/repl-scaffold";
+
+test("archetype step offers boringstack, astro, vite", () => {
+  const step = archetypeStep();
+
+  expect(step.kind).toBe("single");
+  const values = step.options.map((o) => o.value);
+  expect(values).toEqual(["boringstack", "astro", "vite"]);
+});
+```
+
+- [ ] **Step 2: Run to verify failure**
+
+Run: `bun test packages/core/tests/repl-scaffold.test.ts` → FAIL (module not found).
+
+- [ ] **Step 3: Implement `openScaffoldInRepl`**
+
+`archetypeStep()` returns a single-select `IWizardStep` with the three options + a helpful `describe` each. `openScaffoldInRepl`: `deps.suspend()`; run `runWizard` (with `manageInput:false`) over `[archetypeStep(), ...buildScaffoldSteps(manifest, archetype)]` — since later steps depend on the chosen archetype, run the archetype step first (its own `runWizard`), then build+run the remaining steps for that archetype; convert with `stateToAnswers` → `answersToPlan` → `runScaffold({fs:realFs, runner:realRunner, poller:realPoller, ...})`; print the same handoff block `scaffoldMode` prints (dir, sha, boot, gate command); `deps.resume()` in a `finally`. For `vite`, delegate to the existing `--web` skeleton path rather than boringstack clone.
+
+- [ ] **Step 4: Run tests + typecheck/lint, commit**
+
+```bash
+bun test packages/core/tests/repl-scaffold.test.ts && bun run typecheck && bun x eslint packages/core/src/cli/repl-scaffold.ts packages/core/tests/repl-scaffold.test.ts

+### Task 5: In-REPL recipe picker
+
+**Files:**
+- Create: `packages/core/src/cli/repl-recipe.ts`
+- Test: `packages/core/tests/repl-recipe.test.ts`
+
+**Interfaces:**
+- Consumes: `loadRecipes`, `ITaskRecipe` from `../config/recipes`; `runOwnedMenu`/`renderMenu` from `../render/owned-menu`.
+- Produces:
+  ```ts
+  export function recipeRows(recipes: readonly ITaskRecipe[]): IMenuRow[];
+  export interface IReplRecipeDeps {
+    readonly cwd: string; readonly color: boolean;
+    readonly suspend: () => void; readonly resume: () => void;
+    readonly runRecipe: (recipe: ITaskRecipe) => void;
+  }
+  export function openRecipePicker(deps: IReplRecipeDeps): Promise<void>;
+  ```
+
+- [ ] **Step 1: Write the failing test**
+
+```ts
+// packages/core/tests/repl-recipe.test.ts

+```
+
+- [ ] **Step 2: Run to verify failure** — `bun test packages/core/tests/repl-recipe.test.ts` → FAIL.
+
+- [ ] **Step 3: Implement.** `recipeRows` maps recipes → rows (`describe` falls back to `"(no description)"`). `openRecipePicker`: `loadRecipes(cwd)`; if empty, `out` a note and return; else `runOwnedMenu` over `recipeRows`, `onSelect` → `deps.runRecipe(recipe)` + close.
+
+- [ ] **Step 4: Run tests + typecheck/lint, commit**
+
+```bash
+bun test packages/core/tests/repl-recipe.test.ts && bun run typecheck && bun x eslint packages/core/src/cli/repl-recipe.ts packages/core/tests/repl-recipe.test.ts

+### Task 6: Wire `/help` to the browser
+
+**Files:**
+- Modify: `packages/core/src/cli.ts` (the `command()` `case "help"`, and the deps wiring near `handleConfig`)
+
+**Interfaces:**
+- Consumes: `runCapabilityMenu` (Task 3), `openScaffoldInRepl` (Task 4), `openRecipePicker` (Task 5), `loadRecipes`.

+- [ ] **Step 1: Implement `handleHelp`**
+
+Add a `handleHelp` closure mirroring `handleConfig`: on a TTY, `await runCapabilityMenu({ color, hasRecipes: (await loadRecipes(args.dir)).length > 0, suspend, resume, runCommand: (c) => void runLine(c), prefill: (c) => editorControl?.getBuffer().setText(\`\${c} \`), openWizard, showDetail })`. `openWizard("scaffold")` → `openScaffoldInRepl({suspend,resume,out})`; `openWizard("recipe")` → `openRecipePicker({cwd:args.dir,color,suspend,resume,runRecipe:(r)=>void runLine(...) })`. `suspend`/`resume` reuse the exact `handleConfig` deps (including `editorControl?.setInputInert(true/false)` — the inert gate). Non-TTY: keep printing `HELP` (the `formatHelp()` text) so pipes/logs are unchanged.
+
+- [ ] **Step 2: Update `case "help"`** to `await handleHelp();` (was `process.stdout.write(\`\${HELP}\n\`)`), keeping the non-TTY fallback inside `handleHelp`.
+
+- [ ] **Step 3: Verify build + config e2e unaffected**
+
+Run: `bun run typecheck && bun x eslint packages/core/src/cli.ts` → clean.
+Run: `python3 scripts/e2e-config-repl-pty.py` → still `15/15` (shared driver intact).
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add packages/core/src/cli.ts
+git commit --no-gpg-sign -m "feat(cli): /help opens the capability browser (TTY); text fallback off-TTY"
+```
+
+---
+
+### Task 7: Real-terminal e2e + docs
+
+**Files:**
+- Create: `scripts/e2e-help-browser-pty.py`
+- Modify: `package.json` (`e2e:pty` chain), `apps/docs/src/content/docs/cli/interactive.mdx`
+
+- [ ] **Step 1: Write the e2e** (model on `scripts/e2e-config-repl-pty.py`: embedded stub server, `pty.fork`, `NO_UPDATE_NOTIFIER=1`). Assert, on the real buffer:
+  - typing `/help` + Enter opens the browser (title `tsforge — what can I do?` renders).
+  - group headers render (`Build something new`, `The model's tools`).
+  - every visible row shows its `describe` line (pick 3 stable markers incl. the scaffold row `boringstack`).
+  - arrow to a passive row (e.g. `git context`), Enter → the explainer `detail` shows; Esc returns to the list.
+  - arrow to "Scaffold a project", Enter → the archetype wizard opens (`boringstack`, `astro`, `vite` all visible); Esc cancels back to the REPL.
+  - Esc closes the browser; tsforge STILL RUNNING; typing a marker into the editor after renders ONCE (inert gate cleared — the regression we fixed).
+
+- [ ] **Step 2: Run it** — `python3 scripts/e2e-help-browser-pty.py` → `ALL PASS`.
+
+- [ ] **Step 3: Wire into validate** — add `&& python3 scripts/e2e-help-browser-pty.py` to the `e2e:pty` script in `package.json`.
+
+- [ ] **Step 4: Docs** — in `cli/interactive.mdx`, change the `/help` row to "open the capability browser — every command + hidden capability (scaffold stacks, recipes, the model's tools), each with a description; select to run/open" and add a sentence that scaffold + recipes are reachable from `/help`.
+
+- [ ] **Step 5: Full gate + commit**
+
+```bash
+bun run validate   # green: typecheck+lint+format+unit+ALL pty suites (incl. the new one)
+git add scripts/e2e-help-browser-pty.py package.json apps/docs/src/content/docs/cli/interactive.mdx
+git commit --no-gpg-sign -m "test(e2e): /help capability browser (real pty) + docs"
+```
+
+---
+
+## Self-Review
+
+**Spec coverage:** registry (Task 1) ✓; `/help` browser reusing the `/config` driver (Tasks 2–3, 6) ✓; actionable command/wizard/passive selection (Task 3) ✓; scaffold-in-REPL boringstack/astro/vite (Task 4) ✓; recipe-in-REPL (Task 5) ✓; `/` palette stays the runner (untouched — no task needed) ✓; anti-drift test (Task 1) ✓; real-PTY e2e (Task 7) ✓. Deferred items (proactive surfacing, visible-passive annotations, onboarding, generated docs page) are explicitly out of scope per the spec.
+
+**Placeholder scan:** every code step has real code or exact function names from the codebase; test steps have runnable assertions; commands have expected output. No "TBD"/"handle edge cases".
+
+**Type consistency:** `ICapability`/`CapabilityKind`/`CapabilityInvoke` are used identically in Tasks 1, 3, 6. `IMenuRow`/`runOwnedMenu` defined in Task 2 and consumed unchanged in Tasks 3, 5. `openScaffoldInRepl`/`openRecipePicker` signatures match their call sites in Task 6. Scaffold archetype values `["boringstack","astro","vite"]` consistent between Task 4's step and the test.
+
+**One risk flagged for the implementer:** Task 2 refactors the freshly-stabilized `/config` driver. The `scripts/e2e-config-repl-pty.py` (15/15, incl. the double-type + inert-gate regressions) is the safety net — run it after every change in Task 2 and do NOT weaken it. If extraction proves risky, fall back to a standalone `runCapabilityMenu` loop that duplicates the ~40-line keypress loop (accept the duplication over destabilizing `/config`).

Subject: [PATCH 22/58] feat(render): inline menu overlay for config +
 foundation for future menus
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace /config's alt-screen menu with a compact inline dropdown above the
input row (matching the @file picker pattern). The new `inline-menu.ts` module
provides a reusable FLAT menu driver + formatter:

- formatMenuRows(rows, cursor, columns, color) returns a complete overlay
  block: windowed ≤8 rows with scroll indicators, divider, selected row's
  description, and footer hint. No alt-screen, no raw-mode toggle.

- runInlineMenu(rows, deps) owns keypress and navigates ↑/↓, Enter to
  select, Esc to close. Resolves to row index or null.

- Config-menu migrated to use inline-menu via IConfigMenuView callbacks
  (render/close), injected by cli.ts handleConfig. Edit sub-view uses the
  same overlay pattern inline.

- All behavior preserved: toggles stay open + re-render (cursor keeps row),
  text fields inline with validation, editor suspend/resume + inert gate
  (no double-typed text), model persistence to models.json.

Tests: formatMenuRows windowing test added, config-menu 13 pass, e2e 15/15.

From ce77614107d5da676dfa7e7ed08aa2becdbc82c9 Mon Sep 17 00:00:00 2001

Subject: [PATCH 23/58] feat(/help): migrate to inline menu + remove passive
 capabilities
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two coordinated changes to the capability browser:

1. Remove model-tools + passive machinery:
   - Delete toolCapabilities() and TOOL_METADATA entirely
   - Remove "passive" from CapabilityKind (now "command" | "wizard")
   - Remove detail field from ICapability
   - buildCapabilities returns only command + wizard rows (no tools)

2. Migrate /help to inline-menu (same as /config):
   - Replace owned-menu driver with inline-menu + formatMenuRows
   - capabilityRows now returns IMenuRowData (label, hint, describe)
   - Remove showDetail from ICapabilityMenuDeps
   - handleHelp follows handleConfig pattern: suspend→runCapabilityMenu→resume
   - Uses statusBar.setOverlay/clearOverlay for rendering

3. Tests updated:
   - Delete "every model tool has a discovery home" anti-drift test
   - Keep "every slash command has a discovery home"
   - capability-menu tests use formatMenuRows instead of owned-menu

Note: owned-menu.ts remains (still used by repl-recipe.ts).

All tests pass; e2e config script: 15/15 PASS.

From d9127b07dcb6e028f2b95e64b541fa5b585f36ab Mon Sep 17 00:00:00 2001
From: Aleksandar Grbic <ag@dreamdata.io>
Date: Sat, 4 Jul 2026 08:55:26 +0200
Subject: [PATCH 26/58] =?UTF-8?q?fix(render):=20inline=20menu=20=E2=80=94?=
 =?UTF-8?q?=20stop=20stacking,=20style=20only=20the=20selected=20row,=20ad?=
 =?UTF-8?q?d=20title?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The inline menus (/help, /config, recipes) had three rendering bugs:
- STACKING: the overlay could exceed the terminal height, so the status bar's
  relative-redraw couldn't climb to the (scrolled-off) region top to clear it and
  each redraw left a copy. Now the visible-row count is bounded to the terminal
  height, and EVERY overlay line is clipped to the column width (an unclipped
  describe line wrapped, desyncing the row bookkeeping and compounding it).
- STYLING: every row was painted bold (then, worse, all-blue). Now only the
  SELECTED row is brand+bold; all other rows are plain default text (legible).
- LAYOUT: added a bold title at the top; the selected row's description stays at
  the bottom.

Verified in a REAL 14-row terminal (scripts/e2e-help-menu-pty.py, wired into
e2e:pty): no stacking, exactly one styled row, title on top. /config e2e 15/15.

From 890a920de77c62f74019853fd2e29f09259dd888 Mon Sep 17 00:00:00 2001
From: Aleksandar Grbic <ag@dreamdata.io>
Date: Sat, 4 Jul 2026 09:17:02 +0200
Subject: [PATCH 27/58] feat(cli): / palette renders inline (like @/help); fix
 lingering slash on cancel
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The / command palette was the last menu on the alternate screen. It now renders as
the same compact inline overlay as /help and the @ picker, reusing formatMenuRows:
command names as rows, the selected command's summary at the bottom, and the live
query as the overlay title (/co). No alt-screen.

Also fixes the reported bug where cancelling the palette (Esc or backspace-past-
empty) left the trigger '/' stuck in the editor — the cancel path now clears it.

clampIndex moved to inline-menu (the menu core) with a re-export from command-menu
so existing importers are untouched (avoids an import cycle).

Verified in a real terminal: inline (no ESC[?1049h), filters, Esc closes cleanly,
no stray '/', editor live after (7/7). config e2e 15/15, help e2e 6/6, unit green.
e2e palette-open markers updated for the inline title.

Subject: [PATCH 28/58] chore(config): delete dead deprecated renderMenu
 (no-deprecated lint); tidy test

The legacy alt-screen renderMenu(ISetting[]) in config-menu was dead after the
inline migration and only kept for one test; it tripped no-deprecated. Removed it
and its test. bun run validate green (1847 unit + all 4 pty suites).

 name (//sessions)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

runCommand prepended '/' to a capability command that already includes the slash
(registry stores '/sessions'), producing '//sessions' → 'unknown command'. Selecting
any run-command in /help did nothing. Pass the command through verbatim (matches how
the palette dispatches). e2e-help-menu-pty now selects /plan and asserts it actually
runs (mode → normal, no '//', no 'unknown command').

Subject: [PATCH 30/58] fix(editor): preserve trailing bytes after a bracketed
 paste (P1)

feed() discarded any bytes following PASTE_END in the same chunk; a paste
with trailing keystrokes (or a second paste) in one read lost data. IPasteScan
now carries a remainder and processChunk recurses on it. Also adds coverage for
the setInputInert gate.

Regression: editor-paste.test.ts (remainder), editor-controller.test.ts.

Subject: [PATCH 31/58] fix(rules): write generated rule-docs where the reader
 imports it (P1)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

build-rule-docs wrote src/loop/rule-docs.generated.json, but the reader
src/loop/feedback/rule-docs.ts imports ./rule-docs.generated.json — so at
runtime the doc map was empty (0 rules). Point the generator at the reader's
directory, regenerate (117 tsforge rules), delete the orphan.

Regression: rule-docs.test.ts asserts >50 tsforge keys + a known rule id.

Subject: [PATCH 32/58] fix(scaffold): scaffold into a named dir under cwd, not
 a throwaway tmp (P1)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

openScaffoldInRepl created projects in mkdtempSync(tmpdir()) — the scaffold
landed in a temp dir the user never sees. Add a projectDir text step and a pure
resolveScaffoldDest(cwd, name) that resolves a plain name under cwd, rejecting
empties, path separators, and traversal, and refusing to overwrite.

Regression: repl-scaffold.test.ts (dest resolution + rejections).

Subject: [PATCH 33/58] test(wizard): lock the manageInput raw-mode ownership
 rule (P2)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The manageInput:false path (REPL-launched wizard) was untested — the exact
invariant that keeps a wizard from pausing stdin and quitting the process.
Extract the inline decision into a pure exported wizardOwnsRawMode() and unit
test it: manageInput:false / non-TTY / pre-existing keypress listeners / no
setRawMode all yield false; only a standalone TTY owns raw mode.

Regression: wizard.test.ts (wizardOwnsRawMode ownership rule).

MIME-Version: 1.0

Startup redesign:
- Replace the anvil emblem with a large ANSI-Shadow TSFORGE wordmark painted
  with a per-column cyan→indigo→violet gradient (new truecolor() helper).
- Clear the screen + scrollback before the banner so it never renders on top of
  leftover shell output (env dumps, prior command noise).
- Drop the cryptic cwd/scope/gate/session block (those live in /config); show a
  single compact hint bar + styled no-config / plan-mode nudges instead.

Input prompt:
- The › prompt now persists while typing: it's painted as a hanging gutter in
  front of the editor block (was only on the pre-typing placeholder row). The
  editor reserves PROMPT_COLS so wrapping matches the visible width and no row
  exceeds the terminal.

Tests: banner gradient + wordmark; status-bar prompt-in-editor-mode; editor-e2e
and render-e2e cursor/wrap math updated for the 2-col gutter.

Subject: [PATCH 36/58] feat(cli): chat-style message bubbles + kill the
 agent-response gap
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Redesign the conversation transcript (the user asked for bubbles, not blue text
+ a left bar):
- USER messages render as a full rounded bubble (╭─ you ─╮ / │ … │ / ╰──╯),
  sized to content and capped at the terminal width (word-wrapped).
- AGENT messages render as a left-accent card: a rounded ╭ <model> cap, every
  body line prefixed with a │ rail, a ╰ cap when the turn ends. Streaming-
  friendly (any width; code blocks/tables render cleanly inside the rail).

Gap fix: the live stream previously stacked a label newline + the stream
separator + the model's own leading blanks, leaving a big empty block before
each answer. railAgentChunk now swallows leading blank lines until real content,
so the answer starts right under the cap.

Shared helpers (userBubble, agentCardTop/Bottom, agentBar, agentCardBody,
wrapToWidth) power both the settled/replay path (renderMessage) and the live
streaming path (cli.ts). Regression: tests/message-render.test.ts.

MIME-Version: 1.0

Two bugs in the bubble/prompt rendering:
- Plan-mode flow wrote its hints via process.stdout.write, bypassing the pinned
  StatusBar region — corrupting the input row and stranding a › in scrollback.
  Route all four plan-flow writes through echo() (→ statusBar.writeStream).
- Streamed agent text wrapped at the terminal edge, so continuation rows escaped
  the card's │ rail. railAgentChunk now soft-wraps at the card's inner width
  (columns − rail), ANSI-escape-aware, so text can never spill past the rail.

Subject: [PATCH 38/58] fix(cli): agent rail wrap must match true display width
 + leave a margin
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The soft-wrap used a naive 1-col-per-char count and filled the last terminal
column, so wide chars (emoji/CJK) and auto-margin terminals still wrapped the row
themselves — dropping the │ rail on the continuation. Wrap now:
- counts each char by displayWidth (emoji/CJK = 2 cols), and
- leaves the last column empty (columns − rail − 1) so the terminal never wraps.

Subject: [PATCH 39/58] refactor(cli): extract agent-card rail wrapper + lock
 it with tests
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The rail-wrap logic was an untestable inline closure in cli.ts. Extract it to
render/agent-rail.ts as makeAgentRail(rail, innerWidth) — a stateful streaming
wrapper (state persists across token chunks) that prefixes every visual line with
the │ rail, swallows the leading gap, keeps the rail on interior blanks, and
soft-wraps at the card's inner width (display-width-accurate; ANSI escapes pass
through free). Content budget now leaves rail + 2 spare columns so no terminal
wraps a row and drops the rail.

Regression: tests/agent-rail.test.ts — rail on every wrapped row + width bound at
80/92/120 cols incl. emoji/CJK, gap-swallow, interior-blank rail, split-chunk.

drive()'s finally now calls closeAgentTurn(), so the ╰ bottom cap is written the
moment streaming ends. Post-turn hints (plan-mode notice, PLAN review, folding
changes) then land BELOW the sealed card instead of inside it — which had left
the hint un-railed between the last body line and the cap, visually breaking the

The post-turn plan hint was plain full-width text that read like a debug line.
Replace it with a compact styled chip matching the startup plan line: brand ◆ plan
(or ◆ plan ready), dim helper text, green approve. Two variants driven by whether
the agent has proposed a plan yet.

Subject: [PATCH 42/58] refactor(lib): env-gated trace() for silent degrade
 paths (review item 5)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add src/lib/trace.ts — trace(scope, err) gated by TSFORGE_TRACE/TSFORGE_DEBUG
(file path or stderr; no-op when unset). Wire the 10 silent degrade catches in
turn.ts (6), session.ts, run.ts, detect-gate.ts (2) to trace the swallowed error
instead of vanishing — keeps the degrade behaviour, adds observability. Prod stays
silent; TSFORGE_TRACE=1 surfaces what quietly failed (e.g. buildTsService).

Regression: tests/trace-util.test.ts.

Subject: [PATCH 43/58] refactor(gate): split the 1049-line detect-gate.ts god
 file (review item 1)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Pure move, no logic change — behaviour-preserving (all existing gate/loop/session
tests pass unchanged). detect-gate.ts split into focused src/gate/ modules:
  types.ts        IGate, IFileLintProblem, FileLinter
  tool-paths.ts   resolveToolBin + the bundled BIN/CONFIG/CHECK paths
  tsconfig.ts     strict tsconfig overlays + ensureWebGateTsconfig + tscPart
  shell.ts        shSingleQuote + packEnvPrefix
  test-discovery.ts  discoverTestCommand + webTestProbe
  linter.ts       makeFileLinter + formatFile + prettierWriteCommand
  core-gate.ts    buildGate + buildCoreFix
  web-gate.ts     buildWebGate/TypeGate/TscCheck/Fix + WEB_FRAMEWORKS/WEB_PACKS
  index.ts        public barrel
Web scaffolding (scaffoldWeb/installWebDeps/webGuidance/BUILD_PREAMBLE) → src/scaffold/web-scaffold.ts.

Path constants moved a directory deeper, so import.meta.dir joins gained a level
(verified STRICT_CONFIG/STRICT_WEB_CONFIG/BROWSER_CHECK resolve to the package
root). Updated all 18 import sites (4 src, 3 scripts, 11 tests).

Subject: [PATCH 44/58] feat(gate): structured per-stage web gate output
 (review item 3)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The web gate was one opaque `build && tsc && lint && stubs && format && tests &&
render` chain — a failure buried WHICH stage broke in a wall of mixed output.

Add scripts/staged-gate.ts: a bundled runner (mirrors browser-check/stub-check)
that takes a base64 JSON stage list, runs each stage sequentially via the shared
runShellCommand, prints a `━━ <label> ━━` banner + streams output live, and on the
first failure prints `✗ <label> FAILED (exit N)` and stops with that exit code.
buildWebGate now emits `bun staged-gate.ts <payload>` with the SAME commands in the
SAME order (type-aware lint is its own stage) — identical stop-on-first-failure
semantics, legible per-stage feedback. base64 keeps the quoted/&&/env-prefixed
stage commands intact through the shell with zero escaping; onChunk forwards both
stdout and stderr so the gate parser still sees every error.

Regression: tests/staged-gate.test.ts (banners, stop-on-fail, exit-code preserved,
stderr forwarded, malformed payload → exit 2). Web-gate tests decode the payload.

Verified end-to-end: a real web gate on a depless dir prints the vite-build banner
then ✗ vite build FAILED.

Subject: [PATCH 45/58] feat(gate): drop the I-prefix requirement for web code
 (review item 2)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The web profile enforced I-prefixed interfaces (IButtonProps) — non-standard vs
React/shadcn/TanStack, so the model fought its training data every scaffold and
burned turns 'correcting' idiomatic names. Web interfaces now need only be
PascalCase: bare 'ButtonProps' AND 'IButtonProps' both pass. Core/library code is
unchanged — it still requires the I-prefix.

- namingRule (eslint-conventions.ts): web surface emits bare PascalCase (no prefix,
  no Register filter needed — bare already permits 'Register'). Covers both the gate
  and the write-time linter.
- strict.web.eslint.config.mjs: static fallback + header comment updated (resolves
  the review's contradiction — the comment claimed 'no I-prefix' while the rule
  enforced it; now both say bare).
- BUILD_PREAMBLE + web-templates guidance: instruct/illustrate bare names.

Regression: eslint-conventions.test.ts (web bare, core still I-prefix) +
gate-conventions.test.ts (real eslint: web accepts bare 'interface User', core
rejects the same file).

Subject: [PATCH 46/58] refactor(loop): split settleGate into composable,
 testable steps (review item 4)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The ~220-line settleGate mixed auto-fix, gate execution, meta-rules, three
convergence guards, and feedback injection in one body. Extract each seam:
  autoFixStep(ctx) → string[]          (janitor fixers + what they changed)
  runGateStep(ctx, turn)               (validate + live-stream flush)
  runMetaRulesStep(ctx) → violations   (best-effort, change-scoped)
  checkStuck(ctx, state, errs, turn)   (the 3 guards; shared stuckResult shape)
  injectFeedback(...)                  (red-gate feedback + auto-fix notice)
settleGate is now a thin orchestrator; signature + IRunResult|null contract are
unchanged, so both drivers (run.ts / session.ts) are untouched.

Regression: tests/settle-steps.test.ts — checkStuck (converging run never trips,
persistent single error stops, unchanged whole set stops) + autoFixStep (no-op ⇒
[], a real task.fix rewrite ⇒ reported). Guard internals stay covered by
same-persist-guard.test.ts; existing loop/session suites pass unchanged.

Subject: [PATCH 47/58] refactor(loop): group ILoopCtx into ctx.tool + ctx.gate
 (review item 6)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

ILoopCtx had grown into an 18-field grab-bag, and toolContextFor spread eight
fields one-by-one (...(x === undefined ? {} : {x})). Reshape:
  flat core     task, cwd, tsService, report, messages
  ctx.tool      signal, setupWeb, readOnly, policyMode, policyRules,
                interactive, mcpRegistry, touched   (ILoopCtxTool)
  ctx.gate      parse, lintFile, stackProfile, ruleOverrides, onGateChunk
                (ILoopCtxGate)
ctx.tool groups exactly the optional fields IToolContext threads through, so
toolContextFor is now { …identity, ...ctx.tool } — one spread, touched still
shared by reference. Sub-objects are always-present and mutable (the Session
flips policyMode/readOnly/signal/setupWeb/lintFile mid-run). Both construction
sites (session.ts, run.ts + policyCtxFields) nest the fields; write-guard and
all loop accessors updated.

Existing loop/session/tool-accounting suites pass unchanged — behaviour-preserving.

From c7317e7e1f83ce325ea0492f5a9b8ec038659933 Mon Sep 17 00:00:00 2001
From: Aleksandar Grbic <ag@dreamdata.io>
Date: Sun, 5 Jul 2026 00:10:38 +0200
Subject: [PATCH 48/58] fix(cli): --version and --help print-and-exit (bug
 found during refactor)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Neither flag was recognized: an unknown --flag fell through as a POSITIONAL, so
`tsforge --version` booted a session whose task was the literal string
"--version" — while install.sh's post-install message advertises `tsforge
--help  show flags`. Add --version/-V (prints `tsforge <version>` via the
existing currentVersion()) and --help/-h (a new pure cliUsage() kept next to the
flag tables in cli/args.ts), dispatched first in main().

Regression: cli.test.ts — both flags parse as flags (never a task); usage text
covers the advertised surface. Verified live: `tsforge --version` → tsforge 0.27.1.

Subject: [PATCH 49/58] refactor(e2e): shared ptyharness.py for the PTY suite

Extract the duplicated read_until/stub-server/spawn/reap/alive blocks from the
four PTY e2e scripts into scripts/lib/ptyharness.py (~180 LOC of divergent
copies -> one module), and replace blind time.sleep() settles with buffer-aware
drain()/wait_for() so alive-checks fail fast and no redraw bytes are lost.

Scripts keep their scenarios verbatim; assertions unchanged. Flake gate:
bun run e2e:pty green 3 consecutive runs; full validate green (1890 pass).

Subject: [PATCH 50/58] test(e2e): real-PTY coverage for the editor (typing,
 paste, @ picker, wrap)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

New scripts/e2e-editor-pty.py (on ptyharness): the four editor surfaces that
previously had only in-process tests now run against the REAL binary in a real
pseudo-terminal — typing+backspace+Alt-Enter multiline into a submitted bubble,
bracketed paste with embedded CRs landing as ONE message (no per-line submits),
@ file-picker open→filter→select→submit, and 200-char wrap with exactly one
status bar in the final frame. Wired into e2e:pty (now 5 scripts).

20/20 checks, green 3 consecutive runs; full validate green.

From 78b2f6581d069d25747e2cd387f08ebc6db21548 Mon Sep 17 00:00:00 2001
From: Aleksandar Grbic <ag@dreamdata.io>
Date: Sun, 5 Jul 2026 00:58:27 +0200
Subject: [PATCH 51/58] test(e2e): iTerm2 suite on shared helpers +
 paste/@-picker interaction scenarios
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

New scripts/lib/itermharness.py (osascript plumbing, model-aware BAR regex,
window() context manager) shared by the three iTerm2 scripts:
- every window is now closed via try/finally — no stranded GUI windows on a
  failing scenario
- model under test overridable via TSFORGE_E2E_MODEL (BAR regex derives from it)
- two NEW real-terminal scenarios in e2e-iterm-tui.py: bracketed paste with an
  embedded CR (must not submit), and @ picker filter+select landing the path in
  the input row

Verified live: 25/25 TUI checks + 6/6 plan-mode lifecycle against the real
model in real iTerm2; PTY suite unaffected (all green).

Subject: [PATCH 52/58] test: make staged-gate + settle-steps robust to cwd and
 machine load
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- staged-gate.test.ts resolved the runner via process.cwd(), so the suite
  failed when bun test ran from packages/core instead of the repo root —
  resolve relative to the test file instead (latent bug, found by running
  the suite from a different cwd)
- settle-steps' task.fix test sleeps 1s to move mtime; give it an explicit
  30s timeout so a loaded machine can't flake it past bun's 5s default

Subject: [PATCH 53/58] refactor(cli): split cli.ts (2938 lines) into 7 focused
 modules
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Pure move + re-import — same symbols, no logic changes:
- cli/repl.ts        the interactive REPL (repl, initReplSession, approvals)
- cli/model-setup.ts provider config/factory, /model, context-window probe
- cli/logging.ts     spinner, terminal Reporter, --log ledger, log paths
                     (module state now behind setInteractiveStream())
- cli/banner.ts      welcome banner, startup hint, plan chip, resume replay
- cli/gate-setup.ts  gate resolution (resumed > --accept > --web > auto);
                     BROWSER_CHECK now reused from gate/tool-paths
- cli/repl-commands.ts  /sessions /map /review /trace + metrics line
- cli/web-setup.ts   web scaffold + deps install progress

cli.ts keeps main(), runOnce(), and the one-shot modes (559 lines, was
2938). External import paths preserved via re-exports (providerConfig,
isApproval/isPlanApproval, spinner). Parity test now reads cli/repl.ts.

Full validate green (1890 pass + 5 PTY suites); live REPL boot smoke-tested
on the real binary.

- * The tsforge CLI — the product surface over the same engine the eval harness
- * uses (see cli-product-direction). Like any agentic CLI: cd into a repo, run it,
- * and talk. The agent reads/runs/edits the whole workspace by default.
- *
- *   tsforge                       # interactive session in the current repo
- *   tsforge --dir ~/app           # ...in another repo
- *   tsforge "fix the build"       # interactive, with that as the first message
- *   tsforge "fix X" --accept "npm test"   # one-shot: drive to green, then exit
- *   tsforge --continue            # resume the most recent session for this dir
- *
- * The eval-only knobs are now OPTIONAL refinements, never required:
- *   --files "<globs>"   narrow the editable scope (default: the whole workspace)
- *   --accept "<cmd>"    a gate that confirms "done" (default: stop when the model
- *                       stops — like any chat agent). With a gate set, tsforge's
- *                       deterministic check enforces correctness; it can't be faked.
- *   --log               record the full event stream (reasoning, every file the
- *                       agent writes, gate verdicts, timing) as JSONL to an
- *                       auto-named ~/.tsforge/logs/<timestamp>-<id>.jsonl — the
- *                       record to evaluate runs and see where the model got stuck.
- * Slash commands (/help, /clear, /exit) follow the standard harness UX. Provider
- * via TSFORGE_* env.

+ * The tsforge CLI — the product surface over the same engine the eval harness
+ * uses (see cli-product-direction). Like any agentic CLI: cd into a repo, run it,
+ * and talk. The agent reads/runs/edits the whole workspace by default.
+ *
+ *   tsforge                       # interactive session in the current repo
+ *   tsforge --dir ~/app           # ...in another repo
+ *   tsforge "fix the build"       # interactive, with that as the first message
+ *   tsforge "fix X" --accept "npm test"   # one-shot: drive to green, then exit
+ *   tsforge --continue            # resume the most recent session for this dir
+ *
+ * The eval-only knobs are now OPTIONAL refinements, never required:
+ *   --files "<globs>"   narrow the editable scope (default: the whole workspace)
+ *   --accept "<cmd>"    a gate that confirms "done" (default: stop when the model
+ *                       stops — like any chat agent). With a gate set, tsforge's
+ *                       deterministic check enforces correctness; it can't be faked.
+ *   --log               record the full event stream (reasoning, every file the
+ *                       agent writes, gate verdicts, timing) as JSONL to an
+ *                       auto-named ~/.tsforge/logs/<timestamp>-<id>.jsonl — the
+ *                       record to evaluate runs and see where the model got stuck.
+ * Slash commands (/help, /clear, /exit) follow the standard harness UX. Provider
+ * via TSFORGE_* env.

Subject: [PATCH 54/58] refactor(loop): extract staged build + askModel
 decisions from Session
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- loop/staged-build.ts: the design→implement phase orchestration behind a
  narrow IStagedBuildHost seam (gate/tool swap, one send, one gate probe,
  one raw completion); Session methods become thin delegates. Now unit-
  tested against a fake host: gate+tools save/restore ordering, the
  interrupted short-circuit, the green-skip of phase 2, plan-note
  injection, and the from-disk type-contract re-injection.
- loop/model-call.ts: the two pure per-call decisions in askModel —
  selectThinking (forced > repairing > per-send > config precedence) and
  offeredToolsFor (plan mode's read-only tool filter + MCP ride-along) —
  extracted and pinned by direct unit tests (the read-only guarantee had
  none).
- Fixed en route: the staged-build design/implement prompts still told the
  model to I-prefix web interfaces, contradicting the scaffold guidance
  (web is bare PascalCase since a1bf032) — prompts now agree.

session.ts 2118 → ~1930 lines. Full validate green (1921 tests + 5 PTY
suites).

Subject: [PATCH 55/58] refactor(editor): extract the @-mention completion
 state machine
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

editor/completion.ts owns the anchor/query tracking, dropdown navigation,
selection clamping, and accept-replaces-query-keeps-@ behaviour behind
createCompletion(); the controller feeds it key names and re-queries it
after edits. IEditorCompletionSource moved with it (re-exported from the
controller for existing importers).

Now directly unit-tested WITHOUT stdin (tests/editor-completion.test.ts,
9 tests over a real EditorBuffer): whitespace closes the mention, cursor-
before-anchor closes, clamped selection, empty-list accept is a no-op, and
the picked path lands as '@<path> '. The controller keeps the stdin loop,
key dispatch (already a data-driven table), history, and lifecycle.

Note: the planned key-dispatch rework was based on a stale review claim of
a 387-line builder — the table is ~80 lines and already declarative, so it
stays. Full validate green (1930 tests + 5 PTY suites incl. the real-PTY
@-picker interaction).

From 4be4fec086eb767abeac06fc6d11b417dde0e977 Mon Sep 17 00:00:00 2001

Subject: [PATCH 56/58] refactor: trace() the remaining silent degrade paths
 (CLI, editor, file-ops)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Wire the env-gated trace() into the silent catches the review flagged:
cli/model-setup (hostOf, detectContextWindow, warnDefaultModelOnRemote),
cli/logging (newestLogFile), runNotify, file-ops currentFileView, and the
editor's fire-and-forget palette/picker opens. Degrade behaviour unchanged
— TSFORGE_TRACE now shows WHAT quietly failed. Regression test: an
unreachable model endpoint leaves a scoped [cli.detectContextWindow] line
while still returning undefined.

Also fixed en route: agent.constants.ts still described the script tool as
'Opt-in (TSFORGE_SCRIPT)' — it has been ON by default with TSFORGE_NO_SCRIPT
as the kill-switch since 0.23.0.

Dropped from the plan (claims disproven while verifying): the hashline
parse swallow doesn't exist, and the snapshotMtimes/changedSince 'duplicate'
lives only in turn.ts (already traced) — no lib/file-diff.ts needed.

Full validate green (1931 tests + 5 PTY suites).

Subject: [PATCH 57/58] docs: sync the Astro docs with the shipped surface
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- reference/flags.mdx: document the missing env vars, each verified against
  its read site — TSFORGE_TRACE/TSFORGE_DEBUG/TSFORGE_EDITOR_DEBUG (new
  'Debug & tracing' section), TSFORGE_A11Y + TSFORGE_SCREENSHOTS (gate
  oracles), TSFORGE_WEB + TSFORGE_TDD env equivalents,
  TSFORGE_SCRIPT_MAX_CALLS/TIMEOUT_MS, TSFORGE_STATUS (--notify),
  TSFORGE_BASIC_INPUT, TSFORGE_PROPTEST_TIMEOUT_MS; clarify
  NO_UPDATE_NOTIFIER is the cross-tool standard. (TSFORGE_RPC_* stays
  undocumented: internal to the script tool's RPC bridge.)
- cli/interactive.mdx: add the missing /trace and /setup rows; note /quit.
- loop/gate-floor.mdx: new 'Staged gate progress & failures' section
  quoting the real runner strings (━━ banners, ✗ <label> FAILED (exit N),
  stop-on-first-failure).
- scaffold/web.mdx: web interfaces are bare PascalCase now, not I-prefixed.
- astro.config.mjs: input-editor.mdx was orphaned — added under Reference.

Docs build green (46 pages).

+### Staged gate progress & failures
+
+The web gate runs as **named stages** rather than one opaque `&&` chain. Each stage prints a `━━ <label> ━━` banner and streams its output live; a passing stage prints `✓ <label>`. On the first failure the runner prints
+
+```
+✗ <label> FAILED (exit N)

+and **stops** — later stages don't run, and the failing stage's exit code is preserved. So when a build goes red, both you and the agent's feedback loop see *which* stage broke (`vite build`, `typecheck`, `lint`, `type-aware lint`, `stub check`, `format`, `tests`, or `browser smoke`) instead of a wall of interleaved output. The core (non-web) gate is short enough that it stays a plain command chain.

Subject: [PATCH 58/58] fix(render): wrap the --continue replay body inside the
 agent rail

agentCardBody joined rail-prefixed lines with no width awareness, so a long
replayed assistant line spilled past the rail on resume (the live stream was
already wrap-safe via makeAgentRail). It now feeds the settled text through
the SAME ANSI-aware, display-width wrapper the live path uses; renderMessage
threads the real terminal columns through. Tests: long replay wraps with
every body row railed and within width; CJK counts as 2 columns.

Full validate green (1933 tests + 5 PTY suites).
