feat(agents): wire contract + verify + security into feat/bugfix/hotfix (verify-loops lot 4)

lib/verify-secure-loop.md: shared main-loop include. GATE 1 fresh verifier
(blind, contract from disk) → CONFORME straight to GATE 2, ECARTS loop max
3; GATE 2 fresh security-auditor (MODE gate) → PASS to commit, BLOCK loop
max 3 with re-verify-request-FIRST order invariant. Mute agent never a PASS.

feater.md: STEP 0.7 CONTRACT (proportional, silent on a clear feature) +
STEP 3 VERIFY+SECURE via the include. Nominal = one verifier + one security
dispatch; the loop only costs when it loops.

bugfixer.md: STEP 3.5 CONTRACT fed by the DIAGNOSIS (bug report verbatim +
reproduced-then-gone + regression test criteria) + STEP 5 fresh gates via
the include. Renumbered STEP 5 sub-steps (gates before the commit gate).

hotfixer.md: STEP 1.7 CONTRACT (silent autofill, zero questions) + STEP 3
security gate whose FAILURE REVERTS (git restore to pre-flight SHA + escalate
to /bugfix), never loops — the 1-attempt model preserved. No fresh verifier
at hotfix weight (the smoke-check verifies the trivial contract). Adds the
Agent tool to hotfixer.md + hotfix/SKILL.md for the security dispatch.

lib/tests/loops-light.test.sh: 27 structure locks green, shellcheck clean.
Behavioral pipeline dogfood on a fixture (feat adding a feature WITH a SQLi):
GATE1 CONFORME (feature present, SQLi not a conformity gap — orthogonal
gates) → GATE2 BLOCK(1) (checklist caught the %-interp SQLi semgrep's taint
rules missed) → [fix to parameterized] → re-verify CONFORME (order invariant,
feature intact) → re-scan PASS. Loop converges to green.

# Verify + secure loop — shared orchestrator include (feat, bugfix)
Runs in the ORCHESTRATOR MAIN LOOP after the dev step completes. Turns a
finished diff into a verified, security-cleared change through two fresh
gates and bounded loops. The dev stays inline (LRN-083: subagents =
execution + report; loop decisions live here, in the main loop).
Inputs the caller must have ready:
- `CONTRACT`: path to the contract file written by `contract-interview.md`.
- `DIFF`: the range/file-list the dev just produced (e.g. `HEAD` vs the
pre-dev SHA, or the working-tree diff before commit).
- `TEST`: the project test command, if known.
Nominal path is cheap: one verifier dispatch + one security dispatch, done.
The loop only costs more when it actually loops.
## GATE 1 — REQUEST CONFORMITY (fresh verifier)
Dispatch a FRESH verifier subagent (`subagent_type: verifier`, or load
`agents/verifier.md`). Pass ONLY: the `CONTRACT` path, the `DIFF` range, the
`TEST` command. Never pass the dev's summary, never pass a prior iteration's
gaps — the verifier reads the contract from disk and judges blind.
Parse its single `VERIFY — VERDICT:` line:
- `CONFORME` → go to GATE 2. (First-pass conforme = no loop.)
- `ECARTS(n)` → hand the dev the CONTRACT path + the exact `CRITERIA` gap
lines (NOT-MET / out-of-scope), nothing else. Dev fixes inline, then
re-dispatch a FRESH verifier. Repeat. **Max 3 conformity iterations** →
STOP + human escalation with the CRITERIA table (the contract-vs-realized
diff).
- Remaining `UNVERIFIABLE` while all else MET → direct human gate (a dev
cannot fix unverifiability); do not spend a loop on it.
- Out-of-scope files: a dev justification is accepted ONLY through the human
micro-gate that appends `[gated <date>]` to the contract's FILE SCOPE;
otherwise the dev removes the file.
- Structural failure (`ERROR(…)`, missing/duplicated VERDICT line,
unparsable, crash, `CONFORME` without `PROOF`) → retry ONCE with a fresh
verifier; a 2nd structural failure → human escalation. A mute verifier is
NEVER a PASS.
## GATE 2 — SECURITY (fresh security-auditor)
Only after GATE 1 is `CONFORME`. Dispatch a FRESH security-auditor
(`subagent_type: security-auditor`, or load `agents/security-auditor.md`)
with `MODE: gate`, `SCOPE: <DIFF>`. No report path (gate mode is
stdout-only, no Write).
Parse its single `SECURITY — VERDICT:` line:
- `PASS` → done, proceed to commit.
- `BLOCK(n)` → hand the dev the `BLOCKING` list + the CONTRACT path. Dev
fixes inline. Then **re-verify the REQUEST first** (GATE 1, fresh
verifier) — a security fix can drift the behavior — **then re-run GATE 2**
(fresh auditor), in that order. **Max 3 security iterations** → STOP +
human escalation with the BLOCKING table.
- `DEGRADED` (semgrep absent) → does NOT block on the tool's absence; surface
the checklist result + recommend `make plugin`. A DEGRADED run that still
BLOCKs (grep-caught secret/injection) blocks like any other.
- Structural failure → retry ONCE fresh; 2nd → human escalation. A mute
auditor is NEVER a PASS.
## Order invariant
REQUEST conformity is always re-checked BEFORE security on any re-loop — a
security fix that breaks the feature must not slip through because only the
security gate re-ran. Never the reverse order.
