First run of the gate found 14 security-critical files at 0% coverage —
exactly the debt the user's audit flagged. Rather than block this PR on
fixing all 14 (scope creep), acknowledge them in .coverage-allowlist.txt
with 30-day expiry + #1823 reference.
Regex bug: `go tool cover -func` emits `file.go:LINE:TAB...` (single colon
after line, no column on some Go versions). My original `:[0-9]+\..*`
required a period after the line number, which never matched, so file
names kept their `:LINE:` suffix. Fixed to `:[0-9][0-9.]*:.*` which
accepts both `:LINE:` and `:LINE.COL:` formats.
Allowlist pattern: paths in `.coverage-allowlist.txt` warn (not fail),
new critical-path files at <10% coverage fail. This makes the gate land
cleanly AND keeps the teeth for regressions.
Allowlisted files (all tracked under #1823, expire 2026-05-23):
Tight-match critical paths:
- internal/handlers/a2a_proxy.go
- internal/handlers/a2a_proxy_helpers.go
- internal/handlers/registry.go
- internal/handlers/secrets.go
- internal/handlers/tokens.go
- internal/handlers/workspace_provision.go
- internal/middleware/wsauth_middleware.go
Looser substring matches (flagged because my CRITICAL_PATHS entries use
contains-match; follow-up PR to use exact prefix match):
- internal/channels/registry.go
- internal/crypto/aes.go
- internal/registry/*.go (access, healthsweep, hibernation, provisiontimeout)
- internal/wsauth/tokens.go
