[DIRECT] Add ready-to-earn inventory filter regression test (#683)

[elevasyncsolutions-jpg]

Summary

Deterministic regression test proving the public ready-to-earn inventory excludes canonical bounties with:

• verification_ready=false
• Recovery-reserved state
• Invalid terms
• Terminal status (settled, paid, expired, cancelled)

Changes

• scripts/test_ready_to_earn_inventory.py — 16 deterministic tests (no network, no secrets, no wallet)
• scripts/fixtures/rte_inventory_healthy.json — Committed fixture with 1 healthy + 4 excluded bounties

Acceptance criteria

• Covers one healthy funded/claimable/verification-ready bounty and 4 excluded states
• Excluded bounties never appear in ready-to-earn projection
• Source contract and exclusion reason remain visible in broader lifecycle feed
• Exits 0, offline, replayable, no live write

Closes #683

The PR is in the manual-security-review lane because it changes earning-inventory behavior. What passed: it targets the ready-to-earn filter request. What blocks main: inventory must suppress unfunded, unverifiable, stale, or non-canonical records without hiding valid work. Action: run cargo run -p cli -- docs-contract-check and focused inventory tests, then add positive and negative fixtures for funding, verification readiness, cursor freshness, and canonical settlement evidence. Done when the feed result is deterministic and the evidence source is named. Thanks for helping the community grow, and sorry for the review friction. This is not merge, bounty, or payment approval.
