Exited 0 at 2765 s: 96k execs at ~33/s, coverage 1378 edges / 6655
features / 734 corpus, still growing at budget end, zero findings.
Wave 4 is fully done: five of five targets exited 0.
45-min release-budget campaigns, all five targets launched
concurrently: ws_chunk_framing / spec_import / ws_session_opseq /
retry_throttle all exited 0 (coverage saturated or still growing at
budget end; details in plan §5). sse_parser aborted at 1913 s on
FWD-22 (harness-assert fix, previous commit); 45-min post-fix rerun
in flight. Corpus merges deliberately deferred.
Both 10-minute detached campaigns (§5 budget) ran to completion:
sse_parser 18.9k execs / 1100 edges (still discovering at budget end),
ws_chunk_framing 4.8M execs / 245 edges (saturated) — zero crashes,
hangs, OOMs, or leaks on all fork jobs; artifact dirs empty.
One policy gap the first campaigns exposed: the grown corpus entries
(hash-named files in fuzz/corpus/<target>/) leaked as git noise under
the un-ignored corpus dirs. The hash-pattern gitignore now separates
the committed seed-* files from campaign output, per the quinn/h2
model.
docs/plans/fuzzing.md: §3 table marks targets 1-2 implemented; §5
gains the grow-corpus policy + campaign results; §6 sequencing marks
step 1 done. FWD-20 already carried the fix log from 5971c0a.
Verification: corpus replay 80/80 green, cargo test 441 passed, fmt
--check clean.
Adopts the fuzzing pattern proven in alkcall/alktty/alktunnels/
alksocks: fuzz/ workspace with stable-toolchain shared invariant
crate, committed seed corpora, corpus replay as the standing gate,
detached runner for campaigns. Four targets planned — sse_parser and
ws_chunk_framing (this session), spec_import and the stateful wave
(later sessions). §3 table and §6 sequencing track progress.
