Merge pull request 'test: make the Ollama connection-refused test deterministic' (#79) from fix/ollama-test-retry-flake into develop

maxRetries: 0 dropped the transport-retry branches below the 79% branch
coverage threshold. Keep the default retries (and assert all 4 attempts) but
stub Math.random to 0 so the backoff is immediate and deterministic.

+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## What this is
+
+PENNY is an Obsidian community plugin that processes editorial annotations (`%% REWRITE: ... %%`, `%% TONE: ... %%`, etc.) inside novel chapter markdown, calls an LLM to revise the surrounding prose, and writes a new versioned chapter file alongside a review note. It supports Anthropic Claude, Ollama (local), Google Gemini, and OpenAI as providers, with per-tag complexity-tier model routing. Desktop-only (uses Node.js `child_process` for git).
+
+## Common commands
+
+```bash
+npm install            # install deps
+npm run dev            # esbuild watch mode -> writes main.js at repo root
+npm run build          # tsc --noEmit + production esbuild bundle (also auto-deploys, see below)
+npm run typecheck      # tsc --noEmit
+npm run lint           # alias for typecheck (no separate eslint script in package.json; eslint config exists)
+npm test               # vitest run
+npm run test:watch     # vitest watch
+npm run test:coverage  # vitest run --coverage (text + json-summary reporters)
+```
+
+Run a single test file: `npx vitest run test/parser.test.ts`
+Run a single test by name: `npx vitest run -t "parses REWRITE annotation"`
+
+### Build auto-deploy quirk
+
+`npm run build` (production) inspects `../Books/.obsidian/plugins/penny/` and, if the directory exists, copies `main.js`, `styles.css`, and `manifest.json` into it (see `esbuild.config.mjs:48-54`). This is a developer convenience for the maintainer's local vault — do not assume the path exists in CI or for contributors. To test in your own vault, copy or symlink those three files into `<your-vault>/.obsidian/plugins/penny/` manually.
+
+## Architecture
+
+### The hard rule: pure-logic vs Obsidian-shell
+
+The code splits into two zones by **what they import**:
+
+- **Pure-logic modules** (no `obsidian` import, take pre-read strings/objects as parameters):
+  `parser.ts`, `pipeline.ts`, `assembler.ts`, `drafter.ts`, `versioner.ts`, `frontmatter.ts`, `context.ts`, `reviewer.ts`, `voice-check.ts`, `logger.ts`, `migrate.ts`, `project-config.ts`, `quotes.ts`, `utils.ts`, `types.ts`, and everything under `src/providers/`.
+- **Obsidian-shell modules** (free to use Obsidian APIs):
+  `main.ts`, `commands.ts`, `settings.ts`, `setup-wizard.ts`, `statusbar.ts`, `progress-modal.ts`, `error-modal.ts`, `file-conflict-modal.ts`.
+
+`commands.ts` is the bridge: it reads files via the vault API, calls `runPipeline()` from `pipeline.ts` with everything pre-loaded, then writes results back. **Never add `import { ... } from "obsidian"` to a pure-logic module** — that breaks the test architecture (vitest tests for pure modules do not mock Obsidian).
+
+CONTRIBUTING.md describes a `src/core/` + `src/shell/` directory split, but the codebase is currently a flat `src/` with only `src/providers/` as a subfolder. The boundary is enforced by import discipline, not directory layout.
+
+### Pipeline flow (the heart of the plugin)
+
+1. User runs **PENNY: Process this chapter** (or save hook fires).
+2. `commands.ts` reads the chapter, `.version`, `.state.json`, and all context files (style guide, voice tests, characters, outline, wiki) from the vault.
+3. It calls `runPipeline()` (`src/pipeline.ts`) with that input plus a `getProvider` lookup callback.
+4. The pipeline parses annotations (`parser.ts`), filters out already-processed ones via a content hash stored in `.state.json` (`versioner.ts`), assembles per-annotation context (`context.ts`), builds prompts and calls the LLM (`drafter.ts`), then assembles the final new chapter (`assembler.ts`), updates frontmatter (`frontmatter.ts`), runs voice compliance (`voice-check.ts`), and generates a review note (`reviewer.ts`).
+5. `commands.ts` writes the new version file (`ch-05.v2.md`), updates `.version` / `.state.json`, writes the review file, and appends to the activity log.
+
+The pipeline emits real-time `ProgressEvent`s (consumed by `progress-modal.ts`) and supports cancellation via an `isCancelled()` callback.
+
+### Provider system
+
+Four providers live in `src/providers/`: `anthropic.ts`, `ollama.ts`, `google.ts`, `openai.ts`. They all implement the `LLMService` interface from `service.ts` and **do not import `obsidian`**. Instead, they receive an `HttpFn` at construction time. `main.ts` adapts Obsidian's `requestUrl` into that shape:
+
+```ts
+this.providerRegistry = createRegistry(async (params) => {
+  const resp = await requestUrl({...});
+  return { status, headers, text, json };
+});
+```
+
+This is why provider tests can mock the HTTP layer directly without any Obsidian shim.
+
+`router.ts` maps annotation tags to complexity tiers (light/standard/heavy) and resolves each tier to a configured provider+model. The `"auto-latest"` model literal is resolved at call-time to the currently-recommended Anthropic model for that tier.
+
+### Versioning model
+
+Each chapter folder contains:
+- `ch-NN.v1.md`, `ch-NN.v2.md`, ... — successive versions, never overwritten
+- `.version` — plain integer of current version
+- `.state.json` — `VersionState` tracking content hashes of already-processed annotations (idempotency)
+
+A processing run that finds zero new annotations writes nothing. Annotation hashes mean re-running on the same file is a no-op even after a crash.
+
+### Settings + per-project overrides
+
+Settings live in Obsidian's `data.json` (loaded in `main.ts:loadSettings`, with legacy field migration via `migrateSettings` in `types.ts`). A project may override a subset by adding a `PENNY.md` at the book folder root — see `project-config.ts`. The settings tab is `settings.ts`; first-run UX is `setup-wizard.ts`.
+
+### Save-hook debouncing
+
+When `autoProcessOnSave` is on, `main.ts` registers a `vault.on("modify")` handler with a per-file 2-second debounce and a `processingFiles: Set<string>` re-entrancy guard. Without both, processing-induced file writes would cascade into infinite re-triggers. If you touch this code, preserve those guards.
+
+## Code conventions
+
+From `CONTRIBUTING.md` and `tsconfig.json` (strict mode, `noUnusedLocals`, `noUnusedParameters`, `noImplicitReturns`):
+
+- **No `any`.** ESLint warns on `@typescript-eslint/no-explicit-any`. Prefer `unknown` and narrow.
+- **Named exports only**, no default exports (the one exception is `class PennyPlugin extends Plugin` in `main.ts`, which Obsidian's plugin loader requires as default).
+- **Explicit return types** on exported functions.
+- **Pure functions in pure-logic modules**: take inputs, return outputs, no side effects. Side effects (vault I/O, network, child_process) belong in shell modules.
+- TypeScript target is ES2018; bundled as CJS for Obsidian.
+
+## Testing
+
+- Tests live in `test/` and mirror `src/` (e.g. `src/pipeline.ts` ↔ `test/pipeline-cancel.test.ts`).
+- Pure-logic tests **must not** mock Obsidian — that is the whole point of the import boundary. If a test wants to drive the pipeline, it constructs `PipelineInput` directly with raw strings.
+- Provider tests mock the injected `HttpFn`, not network or Obsidian.
+- Test fixtures (style guide, voice tests, sample chapter) are in `test/fixtures/`.
+
+## Branch model
+
+- **`develop`** — default branch, integration target for all PRs.
+- **`main`** — release branch, only receives merges from `develop`.
+- Feature branches: `feature/<short-description>` or `fix/<short-description>`, branched from `develop`.
+
+Commits follow Conventional Commits (`feat:`, `fix:`, `docs:`, `refactor:`, `test:`, `chore:`).
+
+## CI
+
+CircleCI with the `kof22/munitor` orb (see `.circleci/config.yml` and `.munitor.yml`). The pipeline runs `npm run build` and `npm test`, plus SAST and SBOM. There is no separate ESLint job — `npm run lint` is aliased to `tsc --noEmit`, so type errors block CI but ESLint warnings do not.

+# Design: Retry on 429 / transient 5xx with backoff (#15)
+
+**Status:** Draft, awaiting approval
+**Issue:** [#15](https://github.com/KofTwentyTwo/obsidian-penny/issues/15)
+**Date:** 2026-04-27
+**Branch (planned):** `feature/issue-15-retry-backoff` from `develop`
+
+## Goal
+
+Make PENNY's LLM calls survive transient failures. Today, a single 429 or 5xx aborts the entire annotation pass and pollutes the new chapter version with `AGENT-ERROR` markers (`src/pipeline.ts:342-373`) for revisions that would have succeeded on retry. This is a daily-use blocker the moment #9 (parallel annotations) lands, because concurrent Anthropic calls will routinely hit the tier-1 50 RPM / 40K TPM ceiling.
+
+## Architecture
+
+A new `withRetry<T>(fn, opts)` helper lives in `src/providers/node-stream.ts` (same module as `TimeoutError`, `AbortError`, `withTimeout`). Each provider's `complete()` extracts its current request body into a private `doOneAttempt()` method and wraps the call:
+
+```ts
+const maxRetries = request.maxRetries ?? 3;
+return withRetry(() => this.doOneAttempt(request), {
+  maxAttempts: maxRetries + 1,
+  canStillRetry: () => !started,
+  signal: request.signal,
+  onRetry: request.onRetry,
+});
+```
+
+A new `HttpError` class (also in `node-stream.ts`) carries `status`, `headers`, and `body` so the retry helper can read `Retry-After`. `streamRequest`'s return shape is extended with `headers: Record<string, string>` so the streaming path can populate `HttpError.headers` the same way the non-streaming path does. Both paths route HTTP errors through the same `buildHttpError(status, text, headers)` helper.
+
+Retry placement is **inside each provider's `complete()`**, around the entire request path (streaming and non-streaming). This keeps the retry decision close to the code that knows what kind of error was thrown, mirrors the surface change made for `withTimeout` in #18, and avoids a new abstraction layer.
+
+## Components
+
+1. **`HttpError extends Error`** — `{ status: number; headers: Record<string,string>; body: string }`. Replaces the plain `Error` returned by every provider's `buildHttpError`.
+2. **`withRetry<T>(fn, opts)`** — runs `fn`, classifies thrown errors, computes delay, sleeps cancellation-aware, retries up to `maxAttempts`. Options: `{ maxAttempts: number; canStillRetry?: () => boolean; signal?: AbortSignal; onRetry?: (info: RetryInfo) => void }`.
+3. **`isRetriable(err): boolean`** — true when `err instanceof HttpError && (err.status === 429 || err.status === 408 || err.status >= 500)`, OR when `err` is a transport error (none of `HttpError | TimeoutError | AbortError`). False for `TimeoutError`, `AbortError`, other 4xx.
+4. **`backoffDelay(err, attempt): number`** — `attempt` is 0-indexed across retries (0 = wait before retry #1, 1 = wait before retry #2, ...). If `HttpError` and `Retry-After` parses cleanly (seconds or HTTP-date), return that delay. Else `random(0, 1000 * 2^attempt)` (full jitter): max 1s before retry #1, max 2s before retry #2, max 4s before retry #3. Both branches capped at 60000ms.
+5. **`CompletionRequest` additions** — `maxRetries?: number` and `onRetry?: (info: { attempt: number; waitMs: number; reason: string }) => void`.
+6. **`PennySettings.maxRetries`** — default 3, range 0–5 (0 disables). Exposed in Settings → Behavior next to `requestTimeoutMs`. Threaded into `complete()` calls from `pipeline.ts`.
+7. **Pipeline integration** — `pipeline.ts` passes `maxRetries` from settings, supplies an `onRetry` callback that emits `ProgressEvent("retry", { attempt, waitMs, reason })`. Providers stay free of Obsidian dependencies.
+
+## Data flow (one annotation, 429 → 200)
+
+1. `pipeline.ts` calls `service.complete(request)` with `maxRetries` from settings and an `onRetry` that emits a `ProgressEvent("retry", ...)`.
+2. Provider's `complete()` initializes `started = false`, wraps `onToken` so the first call flips `started = true`.
+3. Calls `withRetry(() => doOneAttempt(...), { maxAttempts: 4 /* maxRetries:3 + 1 initial */, canStillRetry: () => !started, signal, onRetry })`.
+4. **Attempt 1 (429 with `Retry-After: 30`):** non-2xx response → `buildHttpError` constructs `HttpError(429, { "retry-after": "30" }, body)` and throws. `withRetry` catches; `isRetriable(err)` is true; `canStillRetry()` is true; `backoffDelay(err, 0)` returns 30000ms. Emits `onRetry({ attempt: 2, waitMs: 30000, reason: "429" })`, `LOG.info("retrying after 429", { provider, attempt, waitMs })`, sleeps 30s with abort-signal listener.
+5. **Attempt 2 (200):** returns `CompletionResponse` normally.
+
+Cancellation during the sleep wakes immediately and throws `AbortError`. If any token reached the user before the error (mid-stream failure), `started === true`, `canStillRetry()` returns false, and the error propagates without retry.
+
+## Error handling
+
+| Error kind | Retriable? |
+|---|---|
+| `HttpError` with status 429 | yes |
+| `HttpError` with status 408 | yes |
+| `HttpError` with status 5xx | yes |
+| `HttpError` with other 4xx (401, 403, 400, 404, ...) | no |
+| Transport error (no recognized class) | yes |
+| `TimeoutError` (from #18) | no — user chose the timeout; retrying doubles the wait |
+| `AbortError` (user cancellation) | no |
+| Any error after first `onToken` callback fired | no — retrying would re-emit tokens |
+
+After all attempts exhausted, throw the last error unchanged.
+
+**Naming convention.** The setting is `maxRetries` — the number of retries on top of the initial call. Default `maxRetries: 3` means up to 4 total calls (1 initial + 3 retries). `maxRetries: 0` disables retry entirely (single attempt, surface the first error). The internal helper signature uses `maxAttempts = maxRetries + 1` so its loop bound is unambiguous.
+
+## Testing
+
+New `test/providers/retry.test.ts`:
+
+- 429 → 429 → 200 succeeds with mock `httpFn`.
+- `Retry-After: 5` honored; malformed `Retry-After: ABCD` falls back to exponential.
+- Honors HTTP-date `Retry-After` (e.g. `Wed, 21 Oct 2026 07:28:00 GMT`) within the 60s cap.
+- 401 propagates immediately, no retry.
+- All 5xx retriable (501, 502, 503, 504 covered by representative tests).
+- `TimeoutError` propagates, no retry.
+- `AbortSignal` aborted mid-sleep → prompt `AbortError`.
+- `canStillRetry` returns false (tokens emitted) → no retry on 503.
+- `maxRetries: 0` makes a single attempt and throws the first error.
+- Per-provider smoke tests proving wiring (one minimal test each for anthropic/openai/google/ollama).
+
+Existing tests remain green; retry is transparent on the success path. Coverage expected to lift from 91% to ~93%; the same PR ratchets `vitest.config.ts` line/statement/function/branch thresholds and `.munitor.yml` `min_instruction` per the standing sprint pattern.
+
+## Files affected
+
+| Path | Change |
+|---|---|
+| `src/providers/node-stream.ts` | Add `HttpError`, `withRetry`, `isRetriable`, `backoffDelay`. Extend `streamRequest` return shape with `headers`. |
+| `src/providers/anthropic.ts` | Refactor `complete()` body into `doOneAttempt`, wrap with `withRetry`. Update `buildHttpError(status, text, headers)` to populate `HttpError`. |
+| `src/providers/openai.ts` | Same refactor as anthropic. |
+| `src/providers/google.ts` | Same refactor. |
+| `src/providers/ollama.ts` | Same refactor. |
+| `src/providers/service.ts` | Add `maxRetries?: number` and `onRetry?: (info) => void` to `CompletionRequest`. |
+| `src/types.ts` | Add `maxRetries: number` to `PennySettings`, default 3 in `migrateSettings`. |
+| `src/settings.ts` | Settings → Behavior UI for max retries (slider 0–5, default 3). |
+| `src/pipeline.ts` | Pass `maxRetries` from settings, wire `onRetry` to a `ProgressEvent("retry", ...)`. |
+| `src/progress-modal.ts` | Render "Retrying after rate limit (attempt N/M, waiting Xs)…" when retry events arrive. |
+| `test/providers/retry.test.ts` | New file covering the cases above. |
+| `test/providers/{anthropic,openai,google,ollama}.test.ts` | Targeted updates for the new error shape and `doOneAttempt` refactor. |
+| `vitest.config.ts`, `.munitor.yml` | Coverage threshold ratchet at PR-finalization time. |
+
+## Open questions
+
+None at design time. The retriable-set decision (5xx range, 408, transport errors; 4xx-other / `TimeoutError` / `AbortError` / post-onToken excluded) follows industry default behavior and the existing repo idioms.
+
+## Out of scope
+
+- Concurrency-aware retry coordination (single global token bucket across parallel calls). #9 will likely want this, but it can layer on top of `withRetry` later.
+- Per-provider retry policy customization (e.g., "retry Ollama 5 times because it's local"). Single global setting is fine for now.
+- Persistence of retry stats. Activity log captures success/failure; not adding a per-attempt audit.
