Restore green pytest suite after dropped-cookie + always-mint drift
The 30+ pytest failures across the wider suite all traced back to two upstream behavior changes: 1. The new dropped-cookie heuristic (commit bfe3044) adds +25 to the score on cookieless requests once the IP is in the Bloom filter. Pre-existing tests using scraper-shaped or no UAs were implicitly relying on the score staying below silent threshold. The new heuristic, combined with the 2026 change that flips the interstitial response from 200 OK to 403 Forbidden, made any "request that wasn't blocked by the rule under test" fall into the challenge-tier 403 path the test couldn't distinguish from real enforcement. 2. The always-mint cookie design (commit f385c9a) emits a fresh __Host-bs_session on every pass through the handler, including pass-tier first visits that previously had cookie=absent in the decision log. Tests that asserted absent / missing now see minted. Three categories of fix applied: a. Heuristic neutralizer in policy/rule tests. Injected `BotShieldScoreSilent 500\nBotShieldScoreHard 600\n BotShieldScoreCaptcha 700` into the config_override blocks of test_policy, test_robots, test_rate_limit_escalate, test_cookie_triggers, test_multi_vhost, test_triggers. Pushes all heuristic-derived tier thresholds well above what the dropped-cookie + missing-UA + missing-AL stack can produce, so the tests exercise their target rule (rate-limit, robots disallow, cookie trigger) without the heuristic interstitial firing. b. 200 → "not 403" assertion relaxation in test_robots and test_policy. Tests hitting nonexistent paths like /public used to see 200 OK from the interstitial; now they see 404 from Apache because the interstitial isn't masking. The tests' real claim is "not blocked", which `!= 403` captures. c. Per-IP isolation in test_cookie_triggers and test_triggers. Two-request sequences where the first request's `flag=` action carried forward and tier_floor'd the second now use distinct fresh IPs to avoid the bleed. d. test_flag_trigger relaxation on the explicit `flag-tier-floor:captcha` reason token. The reason is only emitted when the tier_floor lifts a sub-floor score; with dropped-cookie+honeypot the score now crosses captcha threshold on its own, making the explicit reason redundant. The `flag-tier-floor:form` softer-override regression check still works (the softer floor would NOT appear in either path). e. test_app_claims: cookie state assertion accepts 'minted' (the always-mint result on cookieless first visit) alongside the pre-2026 'absent' / 'missing'. Final test suite: 264 passed, 0 failed (19 deselected browser tests). 9-minute full run.
