What and why

SEEK is the dominant job board in Australia and New Zealand — two markets no per-employer ATS board covers at scale. Issue #1634 flagged it as the highest-value target of its batch but explicitly deferred it pending a spike: a plain fetch of a SEEK search page answers 403, which reads as bot protection.

The spike settled it: the 403 is a Cloudflare interstitial on the human-facing pages only. SEEK's own frontend search API is not gated — GET /api/jobsearch/v5/search answers 200 JSON with no cookie, no credential and no browser-shaped User-Agent (confirmed with no UA at all, curl/8.7.1, Go-http-client/2.0, and the project's own freehire/0.1). Descriptions come from POST /graphql, operation jobDetails, on the same terms. The blocker the issue raised does not exist on the path we crawl.

Closes #1634

Shape

board is an ICT subclassification id, region is the market (au/nz) — the same board-is-a-slice, region-is-a-market split sources/adzuna.yml uses, and region is already part of both the board dedupe key and the board_health key, so the same slice id in two markets is two independently-healthy crawl targets for free. The adapter is an aggregator (not boardless) and a HydratingSource, so a detail request is spent only on a posting the catalogue lacks.

43 boards: 22 Australian slices (~6,471 postings) and 21 New Zealand (~1,323).

Two platform traps drive the design

Both verified live and recorded at the code and in internal/sources/AGENTS.md:

  1. totalCount is a function of pageSize. The same query answered 36 at pageSize=1, 688 at pageSize=20, 680 at 50 and 666 at 100. It can drive neither pagination nor a truncation check, so the response struct does not even declare the field and the walk stops only on the repo's usual "this page added nothing new".
  2. The result window ends near 550. pageSize=100 serves pages 1–5 and answers page 6 empty. Five of Australia's 22 slices hold more than that, so they have a tail no crawl reaches. Ordered newest-first, the reachable window covers roughly the first 24 days of a SEEK ad's 30-day run; the declared 14-day sweepGrace absorbs the drift that would otherwise close-and-reopen those postings each cycle. The marker is sound here specifically because liveness cannot be probed instead — SEEK's own job pages sit behind the same interstitial.

Also handled: where is load-bearing (omitting it collapsed a 688-posting slice to 36); companyName is empty on ~1 posting in 30, where advertiser.description carries the typed name — including the "Private Advertiser" placeholder, which is dropped rather than filed as a company.

Verification

Live run against both markets: 31 postings, every one with an employer, a structured country, a work mode, a listing date and a hydrated description.

go run ./cmd/validate-sources → OK, 205 files. 19 unit tests for the adapter.

Known limitation, deliberately not fixed here: a posting whose detail request fails is ingested body-less and never retried, because the next crawl reports it as seen. seen is a bare membership predicate over ExistingExternalIDs, which reports row existence and is_tech — never whether the row carries a description — so no adapter can tell the two apart. Every HydratingSource in the repo shares this. Closing it properly means changing the hydration contract and its SQL for all of them, not forking the behaviour inside SEEK. Rare in practice: 31/31 details succeeded on the verification run. Written up in the change's design.md.

Checklist

  • I understand this code and can explain how it interacts with the rest of the system.
  • go build ./..., go vet ./..., and gofmt -l . (prints nothing) pass.
  • go test ./... passes (and go vet -tags=integration ./... — no DB/handler code touched).
  • I regenerated committed artifacts when their source changed (none: no SQL, migrations or contracts touched).
  • For design-system/ changes: n/a.
  • For web/ changes: n/a.
  • This stays within freehire's core/extension boundary — one more source adapter behind the existing Source/HydratingSource contracts.

  • Documentation

    • Documented SEEK search behavior, coverage limitations, and API constraints.

SEEK is the dominant job board in Australia and New Zealand, two markets no
per-employer ATS board covers at scale. Issue #1634 flagged it as the highest
value target of its batch but could not confirm it was reachable: a plain fetch
of a search page answers 403.

The 403 is a Cloudflare interstitial on the human-facing pages only. SEEK's own
frontend search API answers 200 JSON to an unauthenticated request with no
browser-shaped User-Agent, and its GraphQL endpoint serves the posting body.
The blocker the issue raised does not exist on the path we crawl.

Board is an ICT subclassification id, region the market, mirroring adzuna's
per-country slices: the whole classification is ~6.5k postings against a ~550
result window, so it is unreachable as one query while its parts are not. The
adapter is an aggregator (not boardless) and a HydratingSource, so a detail
request is spent only on a posting the catalogue lacks.

Two platform traps drive the design and are recorded at the code and in
AGENTS.md: totalCount varies with pageSize (36 at pageSize=1, 688 at 20 for one
query), so the walk trusts only "this page added nothing new"; and the ~550
window leaves five of Australia's 22 slices with a tail no crawl reaches, which
the declared 14-day sweep grace absorbs. SEEK job pages sit behind the same
interstitial, so liveness cannot be probed instead.

Verified live against both markets: every posting came back with an employer,
a structured country, a work mode, a listing date and a hydrated description.
CodeRabbit flagged that a posting whose detail request failed is ingested
body-less and never retried, because the next crawl reports it as seen. The
finding is correct and not fixable in this adapter: seen is a bare
membership predicate over ExistingExternalIDs, which reports row existence
and is_tech, never whether the row carries a description. Every
HydratingSource in the repository shares the behaviour, and the alternative
available at adapter level trades a permanent body-less row for a
temporarily absent one, against the documented rule that a posting is never
lost over a missing detail. Recorded as a known limitation instead.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Trim each candidate before the fallback choice.

firstNonEmpty receives the raw values. If CompanyName is whitespace-only, firstNonEmpty returns that whitespace string, so Advertiser.Description is never used. The final TrimSpace then yields "" and toJob drops a posting that carries a usable advertiser name.

🐛 Proposed fix
 func (p seekPosting) employer() string {
-	name := strings.TrimSpace(firstNonEmpty(p.CompanyName, p.Advertiser.Description))
+	name := firstNonEmpty(strings.TrimSpace(p.CompanyName), strings.TrimSpace(p.Advertiser.Description))
 	if strings.EqualFold(name, seekPrivateAdvertiser) {
 		return ""
 	}
 	return name

Remove "locale" from the market-table description.

seekMarket in internal/sources/seek.go carries host, siteKey and where only. No locale field exists.

Both landed and were verified in production: the adapter (#2013) and the
pacing fix (#2018). seek-source becomes a main spec, carrying the corrected
detail-hydration requirement — paced, and deferring a posting it could not
hydrate rather than storing it body-less.

The archiver compares MODIFIED scenarios by header and reads a rename as a
dropped scenario, so 'Failed detail never drops a posting' keeps its
original header and states the reversed behaviour in its body.
