pre-bash-commit-quality spawned Windows .cmd/.bat linters unquoted, so a spaced path failed, and passed --format compact, which ESLint 9 removed (#3075). Batch executables now run through cmd.exe with each argument carried in an env token and quoted, with quote, NUL, CR and LF rejected before spawn; non-batch Windows and POSIX paths keep direct argv spawn with shell false. ESLint uses its bundled default formatter, present on 8, 9 and 10. Regression tests cover the batch, non-batch and POSIX branches and the formatter change. Independent exact-head review passed with no P0/P1; CI 44/44 at the head.
Address #2921 and complete the segment-anchoring direction in #2979. Preserve explicit absolute exemptions while denying accidental matches in unrelated projects.
Forward-port #2925 for #2924 and verify ASCII and multibyte over-limit input suppression. Supersedes the overlapping direct-entrypoint fix in #2978.

Remove the redundant JSON-RPC initialize fallback from the consolidated MCP health-check batch. A routed 404 already proves the endpoint is reachable, and the real authenticated MCP call remains authoritative. Avoiding the fallback also prevents a stalled GET plus stalled POST from consuming twice the configured hook timeout.
Prevent stale /tmp/harness-cost cache files from affecting Sonnet 5, dated,
near-miss, and cache-rate pricing tests by using Date.now() in each session ID.

The mcp-health-check preflight probes HTTP MCP servers with a bare GET.
Some Streamable HTTP servers route only POST /mcp and answer a bare GET
with 404 (Paper Desktop 0.5.3 is one). The probe scored that as down and
blocked every tool call for the server indefinitely, since the 30s
backoff just re-probes and re-fails.
A routed HTTP response of any status proves the endpoint is reachable,
which is all this preflight claims to check -- 400/401/403/405/406 are
already treated this way for the same reason. Add 404 to the set and let
the real MCP client validate the endpoint.
Adds a regression test that stands up a POST-only server (404 on GET,
200 on POST /mcp); it fails on the current code and passes with the fix.
The preflight probe in mcp-health-check only ever sent a bare GET to the
server URL. Some Streamable HTTP MCP servers route POST exclusively and
answer any GET with 404 — api.telnyx.com/v2/mcp is one — so the probe
failed permanently against a perfectly healthy server.
404 is not in HEALTHY_HTTP_CODES, so every probe failed, the backoff
compounded to the 10-minute ceiling, and the hook blocked every tool call
for that server before it left the machine while `claude mcp list` still
reported it Connected.
Replay a failed GET as a real JSON-RPC initialize POST and accept that as
proof of life. Whitelisting 404 was the alternative, but it would mask
genuine outages on every other server.
Adds a regression test with a POST-only server that 404s all GETs and
validates the initialize body; it fails without this change.

Rebased onto origin/main (49128b576). Fixtures moved from
scripts/hooks/ to /tmp/ecc-pr2380-fixtures/ per reviewer feedback.
(Original commit b0e49036 was based on cc6724ee; main has since
refactored spawnShell to use a shellArgs variable and added
PowerShell .sh fallback paths. This rebase adapts the
const result = spawnSync(...) + __rawInput tagging pattern to
all three spawnSync call sites in spawnShell.)
