1 (artifact bundle): ci_reports writes evidence/MANIFEST.tsv (content hash+len of
every evidence file); attestation verifies completeness+integrity; merge-gates
requires the bundle.
2 (every leaf full evidence): run_all_to streams a full trace+delta record for
EVERY leaf (base 'b' and perturbation 'p'), not a sample.
3 (attestation completeness): attestation enforces a leaf<->trace bijection
(traces == leaves and covered set == leaf set), not just consistency.
4 (collapse derives from full traces): trace_feature_row single-sourced into
collapse_analysis; attestation recomputes each collapse row from the retained
full trace and requires bit-exact match.
5 (mutants through full gates): evaluate_mutants runs each mutant through
engine_acceptance over 128 generated cases (trace/equivalence/domain/
metamorphic/causal), replacing the 64-input local predicates.
6 (trace+delta+future): metamorphic enforces consumed->trace per-case plus
consumed-aggregate delta (>=0.65) and future (>=0.80) rates.
7 (recomputable causal): per-edge intervention records written to
evidence/causal_evidence.tsv; attestation RE-EXECUTES each from its seed and
recomputes base_dv/alt_dv.
8 (no string/comment proof): removed web_assets JS-substring test and the
tautological string assert in ci_reports.
Verified at fast scale end-to-end: 6600/6600 traces reconstructed, leaf
bijection, 1600/1600 causal records recomputed, 600/600 collapse rows derived,
bundle intact.

Builds the browser game around the existing Rust runtime: a window into the
universe, not a second simulation. Pure std, no external crates.
New crates:
- protocol: versioned, hashable client/server messages + hand-rolled JSON value
and total parser (malformed packet -> Err, never panic).
- game_runtime: authoritative match state. Resolves turns through the
INDEPENDENT interpreter (runtime_under_test::native_resolve), not the
reference engine; filters visibility/knowledge; records and regenerates
replays. A match is a pure function of (seed, roster, ordered inputs).
- web_assets/web_client: embedded browser client (arena, rune editor,
knowledge panels, replay viewer) + static HTTP delivery.
- server: std::net HTTP + WebSocket (hand-rolled SHA-1/base64/RFC-6455 framing),
turn timer, disconnect handling, panic-proof dispatch, poison-tolerant lock.
- web_tests: dependency-free WebSocket test client + Phase H gates.
Trust hardening per review:
- game_runtime no longer delegates to reference_runtime::execute; it runs the
independent interpreter that the runtime-equivalence gate proves correct.
- Protocol/socket/replay/visibility/resilience gates are merge-blocking
(added to the merge_group-required job in merge-gates.yml): 1k matches/0
drift, 10k fuzz/0 panics, 100 headless socket E2E, 0 hidden-state leaks.
- Rendered-browser E2E is marked EXTERNAL-BLOCKED: Playwright runs advisory-only
(continue-on-error, artifacts) until CI infrastructure with a browser exists;
it is treated as unsatisfied, not green. The headless 100-match gate is
labeled protocol-level coverage, not rendered-browser coverage.
- README documents the hand-rolled crypto/parser audit risk explicitly.
Fixes an integer-overflow panic in observed-volatility inference (i64 sum /
abs near i64::MIN) that could poison the server mutex.
