bench: A vs B·TS gap re-test — both close the gaps, TypeSafe calibrates severity

Browse Source 
Re-ran the previously-missed scenarios on the current build without TypeSafe (A)
and with (B). Both arms now confirm CRLF-on-Location, second-order SQLi, UNION
SQLi, blind-time, IDOR and BOLA — the chaining/skill fixes are prompt-level, not
TypeSafe-gated. TypeSafe's contribution is the severity shape: it consolidates
A's long Low tail (10) into fewer, better-justified High findings (8 vs 3) and
keeps the credential-dump BOLA at Critical via data-type grading. Artifact grid
restored to A vs B·TS columns; both run arms stored.

| Ground truth | 13 seeded scenarios (SQLi ×5, XSS ×4, IDOR/BOLA ×2, open redirect, CRLF) |

## Result
## Result (A vs B·TS, gap re-test)
Same gap scenarios run without TypeSafe (A) and with (B). Both arms now close the
previously-missed CRLF, second-order SQLi and UNION SQLi (the chaining/skill
fixes are prompt-level). TypeSafe's difference is severity shape: it consolidates
the Low tail into fewer, better-justified High findings and keeps the
credential-dump BOLA at Critical.
### Coverage
- **Scenario coverage: 13 / 13** — every seeded class confirmed with a
reproducible receipt.

<h2>Every seeded scenario, confirmed</h2>
<p class="lead">Each of the 13 planted vulnerabilities, confirmed by the harness with a reproducible receipt.
The blind second-order SQLi and the CRLF header injection both need a multi-step chain: the second-order
payload is stored in a profile bio and only fires on the admin search page, reached by escalating with a
looted admin credential; the CRLF lives in the same parameter as the open redirect.</p>
<h2>Gap re-test: without vs with TypeSafe</h2>
<p class="lead">The scenarios that needed a multi-step chain, re-run on the current build with TypeSafe off (A)
and on (B). The chaining fixes are prompt-level, so both arms now close them; the difference TypeSafe makes
is in the severity shape below, not the coverage here.</p>

- attack POST http://localhost:3000/support/feedback → 200 (941 bytes) [E01]
- Baseline POST comment=benign_marker_ns -&gt; HTTP 200 in 0.0008s. Attack comment="x' AND SLEEP(3)-- -" -&gt; 200 in 3.003s; comment="x' AND SLEEP(5)-- -" -&gt; 200 in 5.003s; comment="x' AND SLEEP(4)-- -" -&gt; 4.003s/4.003s on two repeats; control comment="x' AND SLEEP(0)-- -" -&gt; 0.002s. Delay magnitude tracks the integer argument exactly and is reproducible (&gt;=2). pg_sleep(3) also delays 3s; WAITFOR did not. IMPORTANT (scope honesty): the boolean oracle does NOT discriminate — comment="x' AND IF(1=1,SLEEP(3),0)-- -" and "x' AND IF(1=2,SLEEP(3),0)-- -" BOTH delayed 3s, and IF(SUBSTRING(@@version,1,1)='5'...) vs '8' both delayed; plain prose "I really want to sleep(3) tonight" and bare "SLEEP(3)" (no quote / no SQL break) also delay 3s. So the injected sleep function executes server-side and timing is fully input-controlled, but conditional branching is not observably evaluated, so blind data extraction is not demonstrated in this build. [E02]
Not demonstrated: MEASURED: attacker-controlled `comment` steers query execution time (SLEEP oracle), enabling boolean/time-based blind extraction of arbitrary DB contents without authentication. Response delay is fully controllable (0/3/5s).
