/api/security/stats and scripts/show-tarpit-ips.sh reported "Scan Count",
"offense count" and BLOCKED/TARPITTED status parsed from gpc0/gpc1. No stick
table in this repo has ever stored a general-purpose counter -- the `web` table
stores conn_cur, conn_rate(10s), http_req_rate(10s), http_err_rate(30s), and
the two brute-force tables store http_req_rate(60s). Every one of those figures
was fabricated, and an operator was making decisions on them.
Three independent silences kept it alive:
* `int(parts[3])` on a positional split hit `exp=368842`, raised ValueError,
and the loop `continue`d -- so the endpoint always answered
`active_threats: 0` with an empty list. Live on whp01 it also reported
parts[0], the `0x...:` allocation pointer, as the source IP.
* The command was sent to /tmp/haproxy-cli WITHOUT the `@1` worker prefix.
That is the MASTER CLI socket, which answers "Unknown command: 'show' ..."
-- and socat still exits 0, so the `returncode != 0` guard never fired.
`total_tracked_ips` was the line count of that help text (8) while the real
table held 388 entries.
* The shell consumers wrote `gpc0=${gpc0:-0}`, rendering a field that does
not exist as a confident zero.
Report what the tables actually store, rather than adding gpc counters to make
the old semantics real. Adding them would mean editing hap_listener.tpl -- the
one change here with a silent-total-outage failure mode -- to rebuild
enforcement history that the edge access log (shipped 2026.08.8, on the host at
/var/log/haproxy.log) already records per request, with status codes,
termination states and request references the stick table could never hold.
* haproxy_manager.py: STICK_TABLE_FIELD_CONTRACT names what each table
stores. haproxy_cli() sends worker commands with `@1`, falls back to the
bare form for a plain stats socket, and inspects the RESPONSE BODY because
socat's exit status is worthless here. parse_stick_table_entry() reads
name=value / name(window_ms)=value pairs by NAME, never by position.
read_stick_table() RAISES -- naming the field -- when a row is missing a
contract field, instead of defaulting it to 0.
* /api/security/stats returns the four real counters with their windows, the
true `used:` count, and no invented threat_level/blocked/offense_count.
Fewer numbers, all of them real.
* scripts/show-edge-ip-rates.sh replaces the fabricated report; the four
expected fields are declared once as EXPECTED_FIELDS and drive the parser.
show-tarpit-ips.sh becomes a shim that explains why its numbers are gone
and points at where tarpit events actually live.
* monitor-attacks.sh loses fourteen fabricated "threat" categories and a
composite threat score, all permanently zero; its access-log section now
says the log is on the host instead of silently printing nothing.
* haproxy_tarpit_config.txt -- the never-shipped design sketch these counters
were copied from -- gets a NOT IMPLEMENTED banner.
* scripts/test-stick-table-contract.py (offline, 21 tests) holds the
templates' `store` clauses, STICK_TABLE_FIELD_CONTRACT and every consumer
to each other, and asserts each loud-failure path against the real captured
responses. Template and consumers can no longer drift apart quietly.
No template is touched, so haproxy.cfg is unchanged.
Verified on whp01: total_tracked_ips now tracks `used:` exactly (511 vs the
table's 511, was 8 vs 388), and per-IP values match `show table web key <ip>`
field for field. haproxy PIDs unmoved, `haproxy -c` warnings unchanged, five
customer sites HTTP 200.

- Remove gpc2 from stick-table (not supported in HAProxy 3.0)
- Fix ACL syntax: Change sc_get_gpc0(0) to sc0_get_gpc0
- Fix ACL syntax: Change sc_http_err_rate(0,period) to sc0_http_err_rate(period)
- Fix ACL syntax: Change sc_get_gpc1(0) to sc0_get_gpc1
- Reorder rules to place http-request rules before use_backend rules
- Remove duplicate gpc2 increment rule
These changes ensure compatibility with HAProxy 3.0.11 while maintaining
the tarpit escalation functionality for exploit scanning protection.
