Issue 13 — Stretch: first custom high-value employer adapter

[skcache]

Goal

Extend beyond Greenhouse/Ashby/Lever after core reliability is proven (PRD §17, Issue 13).

Scope (candidate: Amazon — short-lived postings motivated the system)

• Only public employer-facing data
• Explicit rate limits
• Recorded fixtures
• Kill switch

Non-goals

• No browser automation unless absolutely required and approved as architecture change
• Do not weaken V0 reliability to chase one source

Acceptance criteria

• Adapter passes the full failure taxonomy
• Kill switch disables the source without code change
• No personal data in fixtures

Tests

• fixture / parser / normalization / malformed / timeout / 429 / 5xx
• Kill-switch behavior

Dependencies

• Issue 12

EDN architecture review

Yes — new scraping strategy (custom employer surface).
