fix: XDP unsafe loader + Redis sync; enforce 250-line/4-file layout limits
- xdp: CString for if_nametoindex (was UB), real detach via prog fd (fabricated borrow_raw(-1) silently never detached), SAFETY comments, saturating expiry math; +5 unit tests - redis: real pubsub reconnect with exponential backoff (was sleep+return); KEYS -> SCAN in heartbeat sweep - ci: cargo test --all-features, repo-gates job — module size gate (scripts/check_module_size.sh, ratchet baseline) + default-secrets grep - refactor src/ to <=250 LOC/file, <=4 .rs/dir without behavior change; thin bins (rampart.rs 330 -> 6 LOC), new app/, subnet/, intel/, profile/, prefix/, challenge/, filter/, probe/, inventory/, metrics/, node/ - docs: TODO v5.0 (status refresh, new rules, findings backlog), README quickstart now matches real binaries - verify: fmt/clippy -D warnings/test --all-features (164 tests)/clang XDP green

# check_module_size.sh — module size ratchet.
|
||||
#
|
||||
# Project standard (TODO.md §4): max 250 lines per .rs file; max 4 .rs files
|
||||
# per source directory (top level, non-recursive, mod.rs included).
|
||||
#
|
||||
# Rationale — ratchet pattern: the gate blocks regressions immediately while
|
||||
# legacy debt drains away file by file. Paths that currently violate the
|
||||
# standard are pinned one-per-line in .module_size_baseline and are reported
|
||||
# as WARN ("legacy, pending refactor"); only NEW violations fail the build.
|
||||
# Baseline entries that no longer violate are stale and also fail, so the
|
||||
# baseline never hides a shrink that should be locked in — regenerate it with
|
||||
# --update-baseline and commit the result.
|
||||
#
|
||||
# Scope note: we scan src/ only and deliberately do NOT scan tests/.
|
||||
# Cargo treats every top-level tests/*.rs as its own integration-test
|
||||
# binary, so those files must stay "one file per binary" at tests/ root;
|
||||
# splitting an oversized test into a module directory would break cargo's
|
||||
# test discovery.
