Pouya LajevardiandClaude Opus 5 64bce105f8 feat: eyebrow 12px → 13px from one definition; confirm and gate the intake TTL
Two of Pouya's rulings of 2026-08-31, committed as one tree at his instruction
("as-is") because AGENTS.md Change Log entry (ai) covers both and splitting it
would mean rewriting the record rather than moving it. This is a deliberate
departure from one-logical-change-per-commit, recorded here rather than left to
be inferred.

THE EYEBROW. `--text-eyebrow: 0.8125rem` added to tokens.css; `.eyebrow` in
global.css retargeted to it. One edit site, which is what the design system
claimed. 13px is not a rung on the modular ladder — it sits between xs and sm
deliberately, because uppercase mono at 0.18em tracking reads smaller than it
measures. `--text-2xs`'s comment stopped calling itself the eyebrow floor.

The rendered sweep (22 pages × 2 widths, 838 mono elements measured over CDP,
not grepped) found exactly one escape and one deliberate override:

  - h2.footer-heading, 176 instances — an ESCAPED EYEBROW. Five declarations
    byte-identical to `.eyebrow`, differing only in colour. Consolidated to
    `class="eyebrow footer-heading"`; the scoped rule is now colour + margin.
    The colour is load-bearing, not decorative: `.eyebrow`'s own `--text-meta`
    on ink is 3.07:1 and fails.
  - span.eyebrow.brand-tagline, 21 instances — HELD at `--text-2xs`. Measured:
    at 13px the header grows 81 → 83.4px while `--header-h` is pinned at 81 and
    drives `scroll-padding-top`; and with a seventh nav item the CTA lands past
    `.header-inner`'s content edge by 42px at 1216, 18px at 1240, 26px at 1280
    and 1440. Document overflow is 0 in all of those, so no page-level check
    can see it. Insights is that seventh item.

Everything else mono-uppercase is a genuinely different component and was left:
the 0.06em `--tracking-wide` family, the 14px mixed-case designation strip, the
/bio/ print sheet, /contact/'s form labels.

Measured after: contrast unchanged on all 817 instances (11.09 / 8.11 / 5.47 /
5.01:1, all pass at 13px, which is still normal text and needs 4.5:1). Zero
document overflow and identical header geometry at 15 widths. Two eyebrows gain
a line below 414px — /'s hero, already wrapping at 320px before this, and
/insights/'s empty state at 320px only. Accepted, not re-tuned.

docs/02's type spec moved 11–12px → 13px and now enumerates the three 11px
carve-outs instead of implying there are none. The /type-scale/ proof sheet
(d) asked for no longer exists — deleted at build step 2 — so the spec prose is
the proof sheet now.

THE TTL. backend/intake/handler.mjs CONFIRMED to match `AttributeName=ttl`: it
writes `ttl` as a Number, in epoch seconds, at RETENTION_MONTHS = 24. Nothing
needed changing for the enable command.

Removed `|| 0` from the TTL computation. DynamoDB does not expire an item whose
TTL is more than five years past, so `ttl: 0` meant RETAINED FOREVER while
/legal/privacy/ promises deletion — a fallback whose failure mode was the exact
inverse of the claim it was protecting. Unreachable in practice, which is why
it would never have been noticed. A bad value now fails the write.

§7 records TTL as DISABLED at first verification, so the privacy policy's
automatic-deletion promise was unbacked from the moment it was written. §7 is
the only place that status lives; docs/05 and docs/06 carry the constraint and
cite §7, because round 2 of review caught this change set reproducing the SES
DKIM defect — five copies of a status that is about to be re-stamped.

Added, and these are the gate: `TODO(pouya)` on /legal/privacy/'s retention
section, §9 Q60, §12 R19. The page does not publish a period, it asserts a
MECHANISM — deleted by the database rather than by someone remembering — and
nothing in the toolchain can see that. check:claims is frozen with no pattern
for it and deploy does not read docs/06. The copy was NOT softened: it is about
to be true, and weakening a privacy commitment to make it defensible is the
move the rules forbid. What was missing was the gate, not the caveat.

Reviewed by adversarial-reviewer, two rounds (D19 cap), 15 findings, all
accepted, none declined. claims-auditor did not run — D20. Round 1's findings
were almost entirely in prose written that session, and round 2's blocking
finding plus its sharpest should-fix were both defects in round 1's own fixes.

public/pouya-lajevardi-bio.pdf is deliberately NOT in this commit. It was
regenerated and reverted: /bio/'s eyebrow sits inside `.no-print`, so the sheet
has no eyebrow at all, and `cmp -l` showed exactly 10 differing bytes, all in
/CreationDate and /ModDate.

Gates, every one read as an exit status and none through a pipe: check 0,
build 0 (22 pages), check:claims 0, og:proof 0, check:intake 0, lint 0,
minifier tripwire clean, TODO in dist 0. Lighthouse run twice with identical
output: perf 99 on / and 100 on the other 21, a11y 100, best practices 100,
SEO 100 on every indexable page, CLS 0.000, LCP 1.50–2.03s.
