+## badseo harness vs `wrangler dev`: sitemap emits badseo.dev locs locally
+
+`badseo/scripts/run-audit.ts` against a local `wrangler dev --port 8787` fails 4
+sitemap-dependent checks (orphan page, 500, 403, duplicate-content) with
+NOT CRAWLED: wrangler dev adopts the `badseo.dev` custom-domain route as the
+host the worker sees, so `/sitemap.xml` emits `http://badseo.dev/...` locs that
+the crawler's same-origin filter drops. Run it as
+`wrangler dev --port 8787 --local-upstream "localhost:8787"` (after
+`vite build`). Also: `pnpm --filter badseo audit` fails with
+"Unknown option: 'recursive'" from the repo root — badseo is its own pnpm
+workspace, not a root workspace member; use `npx tsx badseo/scripts/run-audit.ts`.

+# Site audit crawl architecture
+
+## Status
+
+Accepted
+
+## Context
+
+The site audit runs as a Cloudflare Workflow. The original design kept all
+crawl state inside the workflow run: the URL frontier and page summaries lived
+in workflow memory and step returns, pages were parsed with a full DOM parser
+(cheerio), and link edges were bulk-inserted into the app database during the
+crawl. On large or slow sites this collided with platform limits:
+
+- **Isolate memory.** DOM parsing expands a page several times over, multiplied
+  by concurrent parses, plus a whole-crawl summaries array that was rebuilt on
+  every workflow replay.
+- **Step-output cap (~1 MiB).** Sitemap seed lists flowed through step returns
+  and could exceed it outright.
+- **Step timeout × retry.** The default 10-minute step timeout with default
+  retries meant a deterministically failing step burned about an hour before
+  the audit died.
+- **Batch head-of-line blocking.** Fixed-size crawl batches waited on their
+  slowest fetch; one tarpit URL stalled a whole batch.
+- **Invisible failure.** Workflow-level kills (OOM, CPU) skip the error
+  handler, so audit rows could stay `running` forever with no recorded reason,
+  and the UI refused to show the pages that had already been crawled and
+  persisted.
+
+## Decision
+
+Split the audit into a control plane and a data plane.
+
+### Orchestration stays in Workflows; crawl state moves to a Durable Object
+
+`SiteAuditWorkflow` remains the orchestrator (phase ordering, durable steps,
+retries). All transient crawl state lives in `AuditScratchpad`, a SQLite-backed
+Durable Object, one instance per audit (`idFromName(auditId)`):
+
+- **frontier** — URL queue and dedup set (URL primary key), with
+  `pending / leased / crawled` states keyed by chunk number;
+- **links** — internal link edges, primary-keyed for idempotent re-insert;
+- **page_mirror** — the few columns the finalize link checks need.
+
+The app database (D1/Postgres) keeps only what the product reads: `audits`
+(plus failure columns), `audit_pages`, `audit_issues`,
+`audit_lighthouse_results`. Link edges are never persisted to the app DB; the
+cross-page link checks (broken internal links, orphan pages) run as SQL inside
+the DO at finalize.
+
+Rejected alternatives: Cloudflare Queues (no dedup, no counters, no completion
+signal — a frontier is mostly those things), a Postgres frontier table (chatty
+hot-path writes, dual-dialect surface), R2 spill files (not queryable).
+
+### Chunked rolling crawl
+
+The crawl phase is a loop of `crawl-chunk-N` steps. Each chunk leases up to
+~200 URLs from the DO and crawls them with a rolling concurrency window: the
+moment a fetch settles, the next URL launches. The window self-adjusts between
+5 and 40 based on recent fetch health (errors, blocked fetches, slow responses,
+oversized bodies shrink it; clean fast batches grow it). A soft deadline ends
+the chunk early and releases unfetched leases. Persistence is pipelined with
+fetching but serialized with itself: page rows and per-page issues go to the
+app DB, link edges and frontier updates go to the DO, and progress counters
+update per sub-batch. Step returns carry only counters, so no step output
+scales with site size.
+
+Everything is idempotent under step retries: chunk-keyed leases (a retried
+step re-receives exactly the URLs its failed attempt held, and refuses a fresh
+claim for an already-crawled chunk number), deterministic page-row ids, and
+insert-or-ignore/replace writes on stable keys.
+
+### Streaming HTML parsing
+
+Pages are parsed with htmlparser2's streaming tokenizer — no DOM is built, so
+per-page memory is constant. cheerio (which uses the same tokenizer
+internally) remains only as a test reference: the parser test suite asserts
+extraction parity against it, and the badseo fixture harness asserts identical
+issue output end to end.
+
+### Failure handling and graceful degradation
+
+- `audits` carries `error_code` (a closed vocabulary mapped from real platform
+  error strings — `step_timeout`, `oom`, `cpu_limit`, `db_error`,
+  `step_output_too_large`, `workflow_internal`, `instance_lost`, `unknown`),
+  `error_detail`, and `failed_phase`.
+- A watchdog on the existing `*/15` cron reconciles audit rows stuck in
+  `running` against the Workflows API; the audit status read path does the
+  same lazily. Only confirmed instance-not-found errors (after a grace period)
+  count as a lost instance, so transient API failures never fail a live audit.
+- A failed audit shows everything crawled before the failure ("stopped early
+  after N pages") instead of hiding results.
+- The start URL follows redirects (with per-hop SSRF revalidation) before the
+  crawl anchors its origin, so apex→www and cross-TLD redirects don't dead-end
+  the crawl after one page.
+
+### DO lifecycle and platform-limit guards
+
+- `destroy()` (delete alarm, then all storage) runs on audit success and on
+  audit deletion. Every DO construction schedules a 7-day self-cleanup alarm,
+  so any instantiation — including a write racing in after destroy, or a
+  workflow that dies before seeding — is eventually wiped. Failed audits keep
+  their scratchpad for those 7 days as the resume/debug artifact.
+- Guards where the platform has hard edges: link writes stop at a storage
+  budget (below the free-plan per-object SQLite cap; orphan detection is
+  skipped when the link graph was truncated), discovered-URL batches are
+  capped below the serialized-RPC limit, and sitemap documents are read up to
+  a byte cap and skipped whole beyond it.
+
+## Consequences
+
+- Workflow heap and step state are O(one chunk) regardless of site size; the
+  OOM/step-output failure classes are gone by construction.
+- Hostile or slow sites degrade to a slower window and finish (or fail with a
+  classified reason and visible partials) instead of burning an hour of
+  retries.
+- Every failure is aggregable by `error_code` in plain SQL, and zombie
+  `running` rows self-heal.
+- Crawl-state code is provider-independent (DO SQLite exists in workerd), so
+  self-host does not add a dialect surface for the frontier or links.
+- The scratchpad is opaque from outside the DO; the 7-day retention of failed
+  audits' state is the debugging window.
+- Resume-from-frontier ("retry finishes the last N pages instead of
+  recrawling") is enabled by the retained frontier but intentionally not
+  built yet.
