# CLAUDE.md — operating instructions for Claude Code

## Read this first

1. **`AGENTS.md` is the source of truth for this project.** Read it in full
   before your first edit in any session. It carries the locked decisions, the
   credential register, the open questions, and the full history.
2. **You are required to maintain `AGENTS.md`** under the constitution written at
   the top of it. Update *Current Truth* in place; append to the *Change Log*,
   newest first; never edit a past entry; never delete history. Record decisions
   and plans, not only executed work. Stamp facts `[verified YYYY-MM-DD]` or
   `[assumed]`.
3. Update it **at the end of every working session**, not only when something
   ships. A session that produced a decision and no code still produces a Change
   Log entry.
4. **Read `AGENTS.md` §12 Standing Reminders at the start of every substantial
   session and surface anything live to Pouya.** These are decisions he parked
   deliberately, not settled matters — R1 in particular is his explicit
   instruction to keep raising the licensure wording. A parked decision that
   stops being raised has quietly become permanent, which is the failure mode
   §12 exists to prevent.

## The one rule that matters more than the code

This is Pouya's public marketing surface, and the site it replaces carried
fabricated credentials. **No factual claim about him, his credentials, his
experience, or his practice may appear on a public page unless it is in the
Verified table in `AGENTS.md` §4.**

(§4 does not verify licensure either way — so do not describe him as
"licensed", or as a "legal professional", anywhere, this file included. State
the reason for the rule, not a credential the register cannot vouch for.)

If a page needs a fact you do not have:

- Do not infer it from context.
- Do not soften it into something defensible ("extensive experience", "years of").
- Do not carry it over from the old site — the old site contained a fictitious
  founder, invented matter values, and a fabricated testimonial.
- **Leave `TODO(pouya): <the exact question>` in the source, and add the question
  to `AGENTS.md` §9.** A build that fails on an unanswered question is a correct
  build.

Read the Forbidden table in §4 before writing any statistic, number, or
superlative.

## How work is executed here

Pouya is the architect. He makes the decisions and hands you the task. **You
implement, then you adversarially review your own work before calling it done.**
This is the standing agreement — it applies to every substantial change without
being restated in the prompt.

**Run `/build <task>` for any substantive change.** It encodes the loop:

1. **Plan** — read `AGENTS.md` (including §12 Standing Reminders, and surface
   anything live), read the governing specs, name the decisions the task touches,
   and **stop and ask on any conflict**. A blocked build is a correct build.
2. **Implement** — following the conventions below.
3. **Adversarial review** — invoke `adversarial-reviewer` on the diff. **D20:
   `claims-auditor` does NOT run per step.** It runs once, at cutover, over the
   whole finished site.
4. **Resolve** — fix each finding or decline it with a stated reason. Re-review
   material fixes.
5. **Verify** — run the checks. Never report a check as passing that you did not
   run.
6. **Record** — append the `AGENTS.md` Change Log entry.

`/review` runs phase 3 alone. `/wrap` runs phase 6 at session end.

**Agent definitions load at session start.** An edit to `.claude/agents/*.md`
does not reach the session you made it in — the brief in force is the one that
was on disk when the session began. After committing a change to one, **restart
before relying on it, and say in the report which version actually ran.** Found
2026-08-30: the gloss lens was added to `claims-auditor` and the agent then
reconstructed it from the `AGENTS.md` Change Log rather than having it in its
brief, which is luck, not process.

**Think deeply before acting.** Extended thinking is on by default for this
project (`.claude/settings.json`), and `/build` and `/review` request it
explicitly. The planning and review phases are where it earns its cost — a defect
reasoned out before implementation is far cheaper than one found after.

### Why the review is adversarial, and what would break it

Two rules make the difference between a review and a rubber stamp:

**Do not brief the reviewers on why your work is correct.** Give them the diff
and the specs, nothing else. Your rationale anchors them, and an anchored
reviewer produces agreement rather than review. They must form an independent
view from the artefact — that independence *is* the mechanism.

**The reviewers are instructed to treat uncertainty as a defect.** They will
sometimes be wrong, and that is the intended trade. Explaining why a finding is
mistaken costs minutes; a missed defect on this project's public marketing
pages costs considerably more — the site this replaces carried fabricated
credentials, and that is the standard being corrected. Do not read a finding as
an accusation, and do not argue a reviewer down — either fix it, or record the
reason you declined it so a later reader can see the judgement was made rather
than missed.

**Two reviewers, because they catch different things — but they no longer run at
the same time.** `adversarial-reviewer` reads the code. `claims-auditor` reads the
copy against the §4 register and knows nothing about whether the code is elegant.
A generic reviewer consistently under-weights the professional-conduct check,
which is the highest-stakes failure mode on this project — so it keeps its own
pass rather than being folded into the code review.

**D20, 2026-08-30 — the claims pass moved to cutover.** Per step it is
`adversarial-reviewer` alone. `claims-auditor` runs **once, over the whole
finished site**, as a blocking item on `docs/06`'s cutover checklist. Pouya's
reasoning, and it is a calibration and not an erosion: nothing has shipped, so
every claims finding so far has been about a page no visitor can reach — the risk
is deferred to cutover anyway, and one pass over twenty finished pages catches
**more** than nine passes over drafts, because it sees the site as a reader does.
The `/med-arb/` ADRIC gloss is the proof: no individual claim was false, the
defect was **adjacency**, and adjacency does not exist until the pages sit next to
each other. The code reviewer stays per step because what it catches **compounds**
— an accessibility or crawlability defect propagates into the next page built on
it, and a claims defect does not; it sits there until someone reads it.

**What it costs is recorded in `AGENTS.md` D20, not summarised away here.** Read
it before proposing any further relaxation: `claims-auditor` has caught defects
that would have been serious on a live page, and D20 accepts that such a defect
may now live in an unpublished draft for weeks. Two things carry that risk in the
meantime — **`npm run check:claims`, which is unchanged and runs on every build
and both deploy paths**, and **Pouya reading the copy as it is built**. Neither is
optional, and neither is a substitute for the cutover pass.

## Commands

```bash
npm install
npm run dev        # local dev server
npm run build      # static build to ./dist
npm run preview    # serve ./dist locally
npm run check      # astro check — type and template errors
npm run check:claims  # §4 Forbidden, enforced on dist/ — run it after a build
npm run check:intake  # the form's field table vs the Lambda's — they are two on purpose
npm run og:proof   # every og:image resolves; every card headline IS its page's <h1>
npm run lighthouse # the performance budget. LOCAL ONLY — needs Chrome, not in CI
npm run bio:pdf    # re-renders the committed one-page PDF from /bio/. LOCAL ONLY
npm run icons      # re-derives public/favicon.ico from the brand master. REGENERATOR
npm run lint       # eslint + prettier check
npm run format     # prettier — rewrite files in place
npm run deploy     # build + deploy from this machine (see docs/06)
```

**Four of those are gates and two of them cannot run in CI.** `check`,
`check:claims`, `check:intake` and `og:proof` are pure Node and run anywhere.
`lighthouse` and `bio:pdf` drive an installed browser, and the Gitea runner has
none — so they are keyboard gates plus blocking items on `docs/06`'s cutover
checklist, and **they are deliberately not wired into `npm run build` or either
deploy path.** Do not describe either as gating a deploy: a check described as
running where it cannot is the defect `AGENTS.md` Q22 turned out to be.

**`bio:pdf` and `icons` are REGENERATORS, not gates** — they rewrite committed
artefacts (`public/pouya-lajevardi-bio.pdf`, `public/favicon.ico`) rather than
checking anything, so they are run deliberately and their output is committed.
⚠️ **`LOCAL ONLY` above means a different thing for each, so do not read the two
labels as one.** `bio:pdf` **cannot** run in CI — it drives a browser. `icons`
is pure Node and **could**; it is out of the build because a build should not
silently rewrite an artefact a human approved, which is why it is labelled
`REGENERATOR` rather than `LOCAL ONLY`. It regenerates the favicon **only** — the touch icon
is hand-made and must stay opaque cream (`docs/reference/brand-assets.md`
§The icon set).

**`og:proof` and `check:intake` exist because two facts in this repo are
deliberately duplicated**, and a duplicated fact needs a mechanism rather than a
comment. `og:proof` compares each generated OG card's headline against its page's
own `<h1>` — **text baked into a JPEG cannot be grepped by `check:claims`**, so
that comparison is the only thing keeping card copy inside the claim register.
`check:intake` compares the form's field table against the Lambda's, which are
independent because a server that validates against a list the client shipped it
is not validating.

## Conventions

**Framework.** Astro **7.x**, `output: 'static'` (D1 as amended). Never introduce
a server runtime without a Change Log entry recording why. The major is pinned
deliberately — check `npm view astro version` before changing it.

**JavaScript.** Default to zero. Reach for an Astro island only when a feature
genuinely cannot be CSS or progressive HTML. If you add a `client:*` directive,
say why in the Change Log. A `<details>` element beats a JS accordion.

**Styling.** Plain CSS with custom properties. No Tailwind, no CSS-in-JS, no
utility framework. Every colour, space, and font size comes from a token in
`tokens.css` — no raw hex values and no magic numbers in component styles.

**Accessibility is a build requirement, not a polish pass.** Semantic landmarks,
one `<h1>` per page, heading levels never skipped, visible focus states, all
interactive elements reachable by keyboard, `prefers-reduced-motion` honoured on
every animation. Gold `#c9a876` never sits on cream — it fails contrast at
2.10:1. See `docs/02-design-system.md`.

**Anything a spec makes a claim about must be reachable from the repository.**
If the artefact lives only in Drive, in a console, or on someone's laptop, no
reviewer can compare the claim against it and the claim is **unverifiable by
construction** — not merely unverified. Commit the artefact, or commit a faithful
extract with its provenance and the command that produced it.

This has cost twice. `AGENTS.md` Q24 was the AWS hosting guide, the only record
of how the infrastructure was hand-built, living outside the repo. Q32 was the
infinity mark: it was traced from the old site's *loading placeholder*, the
source comment said so in as many words — and **two adversarial review passes
still could not catch that the shape was wrong**, because the real artwork was
not in the repo to compare against. Stating a doubt is not enough when the thing
that would resolve it is unreachable. Tracked as R14.

**A command that did not run is not evidence of absence.** Check that a tool
exists before trusting its silence, and read exit status, not just stdout. This
project ran `timeout 60 ls "$DRIVE"` four times, got empty output each time, and
reported the brand assets unreachable — `timeout` is not installed on macOS, so
the command had never executed and the directory was fully readable all along.
Empty output from a command that failed to start looks exactly like empty output
from a command that found nothing. Same family as *a sweep is a command, not a
claim*: the claim must rest on output you actually read, from a command that
actually ran.

**And never suppress stderr in a verification script.** *Pouya's convention,
2026-08-28, from verifying the deploy credential (`AGENTS.md` Q22).* This is the
rule above from the other direction, and it is the more dangerous direction:
**`2>/dev/null` converts "it failed" into "it found nothing", and those are
opposite results.** His first pass at eight `simulate-principal-policy` checks
returned empty for all eight; the suppression was hiding an `InvalidInput` error,
and the empty output was then explained with a guess — *"probably lacks the
permission"* — which is the answer the check was supposed to produce, arrived at
without the check running. The actual cause was a **zsh parameter-expansion bug**:
`$ACCT:user/` parses `:u` as a history modifier and yields `327082975128ser/`.
Braces fixed it.

So: no `2>/dev/null` in anything whose output you intend to believe, read the
exit status, and when a result is empty **remove the suppression and look before
proposing a cause.** A guessed explanation for an empty result is worse than no
result, because it closes the question.

**And never TRUNCATE the output of a check you intend to believe.** *Added
2026-08-29, from build step 5.* This is the stderr rule's twin and it is easier
to commit, because the command runs and the pipe looks harmless. `npm run check`
prints its verdict as three lines — `- N errors`, `- N warnings`, `- N hints` —
followed by a blank line. **`npm run check 2>&1 | tail -3` therefore returns
warnings, hints and the blank line, and silently drops the errors line.** It was
run four times that way and reported as passing each time; `astro check` was
exiting **1 with 10 type errors**, and both deploy paths run it before the build,
so nothing could have shipped. `adversarial-reviewer` found it.

The fix is not a bigger `tail`. **Read the exit status** — `cmd; echo "exit=$?"`
or `cmd || echo FAILED` — because it is the one signal a pipe cannot silently
reshape. `head`, `tail`, `grep -c` and `| grep -i error` all have the same
failure mode: they turn a verdict you did not read into a verdict you assert.
Same family as *a sweep is a command, not a claim*, and note the asymmetry that
makes it dangerous — the truncation only ever hides the bad news, because the
error line comes first.

*Corroborated the same day, twice, in the same session and both in zsh:*
`grep -rn $EX 'Mediator-Arbitrator'` printed an option error and no matches —
which reads as clean — because zsh does not word-split unquoted variables; and a
digest-comparison loop using `set -- $pair` printed **`DIFFER` on all five rows**,
which reads as "the source changed under me", because the loop body received one
argument and the comparison never ran. Prefer `git grep`, quote or array-expand
anything you pass as flags, and re-check any result whose shape is "uniformly
bad".

**zsh does not word-split parameter expansions; a loop over `$VAR` runs ONCE —
use command substitution or arrays, and assert the iteration count.** *Pouya's
convention, 2026-09-01.* `for p in $PAGES` iterates one item, not twenty-two,
and `node probe.mjs 320,360 $P` measures one page — both of which then report
"max=0, nonzero=0" and read as a clean sweep. `$(cat file)` and `${=VAR}` do
split; `"${(@f)VAR}"` splits on newlines. **The fix is not remembering which:
assert the count before reading the result** — a probe that says how many rows it
measured cannot silently measure one.

**And re-check "uniformly GOOD" too — that is the dangerous half.** *Added
2026-08-30; sharpened on Pouya's instruction 2026-08-31, as "the sharpest
instrument finding yet".* The same `set -- $pair` loop recurred while confirming
nine restored files matched a saved copy, and this time it printed **`same` on
all nine**: `shasum` was handed both filenames as one argument, errored, and left
both variables empty, so `"" = ""` passed.

**The distinguishing property, and it is the whole rule: a broken verification
that fails loudly is safe; one that passes uniformly is not.** `DIFFER` on every
row announces itself — it is alarming, so it starts an investigation, and the
investigation finds the broken loop. A uniform pass is **the result you were
hoping for, so it ends the check** instead of starting one. The two failures come
from the identical bug and only one of them is survivable.

So a comparison must **assert that both things it compares exist** before
comparing them — that is the assertion the shell loop skipped, and it is what
turns this class of bug back into the loud kind. Note the same hole in `git grep`:
it silently misses untracked files, so a clean sweep across new work means
nothing until the files are staged.

**A parent cannot style a child component's root element.** Astro does not pass
a parent's scope attribute down, so `<Button class="header-cta" />` compiles the
parent's rule to `.header-cta[data-astro-cid-<parent>]` while the rendered `<a>`
carries only `<Button>`'s own cid. **The rule silently never matches** — no
error, no warning, and the CSS looks correct in the source. Wrap the child in an
element the parent owns (`<div class="header-cta"><Button …/></div>`), or reach
it deliberately with `:global()` from a parent-scoped ancestor. Inherited
properties (`white-space`, `color`, `font-*`) do cross the boundary and are the
exception. This cost a header CTA that was documented as hidden on mobile,
was not hidden, and sat 75 px short of the right edge on desktop — both found by
measurement, neither by reading. It will recur with `PracticeCard`,
`ArticleCard`, and `Pill`.

**Never write the `animation` shorthand beside `animation-timeline`.** Longhands
only — `animation-name`, `animation-duration`, `animation-timing-function`,
`animation-fill-mode`, then `animation-timeline` and `animation-range`.
`scroll()` and `view()` are not legal components of the shorthand, and Lightning
CSS folds the two declarations together on minify into something invalid, which
is then discarded whole. **It works in `npm run dev` and is dead in
`npm run build`** — the worst shape a defect can take. It happened twice in one
session, the second time inside the fix for the first. `/build` Phase 5 greps
`dist` for it; do not remove that check.

**Images.** Astro `<Image>` with explicit width and height. AVIF/WebP with
fallback. Never base64-inline an image into HTML — the old site did this with
~1 MB of logo PNGs — a figure `AGENTS.md` Q34 is now open against, so treat the
rule as standing on its own merits rather than on that number.

**Fonts.** Self-hosted, subset, `font-display: swap`, preloaded. No Google Fonts
request at runtime — it costs a round trip and adds a third-party call to a
page that collects legal inquiries.

**Every page ships with:** a unique `<title>` and meta description, a canonical
URL, Open Graph and Twitter card tags, and appropriate JSON-LD. See
`docs/04-seo-spec.md`. A page without these is not finished.

**A version pin is verified against the registry, never recalled.** Before you
write or change any dependency version, run `npm view <pkg> version` and pin
against what it returns. One second of checking; a stale pin costs a migration.
This rule exists because `astro: "^5.0.0"` was written from memory and was
**two majors stale on the day it was written** — which meant shipping a
framework carrying high-severity XSS advisories. The same check applies to
every pin in `package.json`, not just the framework.

Re-check currency at each phase boundary in the build order (`AGENTS.md` R11),
not only when something breaks.

**`AGENTS.md` §7 is the single source of truth for operational facts.** Resource
IDs, regions, DNS records, credential state, service status — these live in §7
and nowhere else. Specs in `docs/` **cite** §7; they do not restate it. Write
"the region `AGENTS.md` §7 records", not the region. Same for bucket names,
distribution IDs, DKIM tokens, endpoints, and account identifiers.

A duplicated fact is a fact that will eventually be wrong in one place, and the
copy that goes stale is the one nobody re-reads. This rule exists because
`docs/05-backend-spec.md` carried its own copy of the SES DKIM table, a
correction reached §7 and never reached it, and the stale copy ended up telling
an operator to delete the three records that authenticate outbound mail —
under the heading "Never delete".

**A measurement is a claim about your instrument until you check the
instrument.** This has now cost nine times, and the shape is identical every
time: a number that looks like a finding, from a probe nobody validated.

- `timeout 60 ls "$DRIVE"` — **the command never ran.** `timeout` is not
  installed on macOS. Empty output from a command that failed to start looks
  exactly like empty output from a command that found nothing, and it produced a
  report that the brand assets were unreachable when the directory was fully
  readable.
- **`1.23:1` for the traced mark** — the bounding box of the path's *coordinate
  hull*, not of the curve. A cubic's control points sit outside it, so the box
  was 33% too tall while giving the *correct* width — which means the obvious
  sanity check, "does the width look right?", passes.
- **"the mark renders at 24px"** — the harness reported the worst-deviating
  instance on the page, not the instance under discussion, which was exact.
- **"0 overflow at every width"** — true, and it measured the *document*. A flex
  child was absorbing the deficit by being crushed to aspect 0.891. **Measure
  the elements, not only the page.**
- **`img.naturalWidth` = 64 at DPR 1, 2 and 3** — which reads as *the density
  ladder is not being generated at all*, a shipped defect on every page. It is
  **density-corrected by spec**: a 192px file selected at `3x` correctly reports
  64. The files on disk were 64 / 128 / 192 all along.
- **"10 distinct contexts" from `grep -roh '.\{50\}X.\{50\}' dist/ | sort -u`**
  — **`grep -o` takes NON-OVERLAPPING matches.** On minified HTML a page is a
  handful of very long lines, so an early window eats the characters a later one
  needs and occurrences vanish silently. A whole shipped sentence was missing
  from the list. **A `grep -o` window count is not an enumeration** — to count
  occurrences of a string, iterate every match position, or `grep -o` the bare
  string with no context window.
- **An ink bounding box of `48x48` filling the whole 48 px favicon** — which
  reads as *the regeneration blew the mark up to the full square*. The probe
  identified ink as "differs from cream", which is **correct on a matted icon and
  meaningless on a transparent one**, because `alpha = 0` pixels still carry RGB
  `(0,0,0)`. **Nothing about the probe changed — the class of input did**, and a
  probe cannot tell you that. Composite over a known ground first, so both things
  compared are the kind of thing the instrument was built for.
- **A contrast ratio of `14.02:1` for the mark's darkest ink** — computed from a
  raw channel value **without asking what alpha it is painted at**. Exactly one
  pixel carried that colour and its alpha was 251; a `>= 250` filter let it
  through and the ratio was then taken as if it were opaque. **It is a number
  about a colour that is never painted.** Composite against the actual ground
  before measuring contrast, and take "the ink colour" only from fully opaque
  pixels.
- **`POST /api/intake` returning 403 — read as "the route does not exist", on a
  LIVE site.** ⚠️ **A bare POST to `/api/intake` returns 403 BY DESIGN.** The
  handler rejects a request with no `Origin` header, and **`docs/09` §7.1 says so
  in as many words** — *"403 means the `Origin` header did not arrive"* — three
  lines below the probe it prescribes. **The only valid route probe is `docs/09`
  §7.1 verbatim, `Origin` header included; a 403 without that header is not
  evidence about the route.** Run correctly it returns **303** to
  `/contact/could-not-send/`, which is the handler answering as designed. This
  fired **twice on this project in two days** — Pouya's own probe tripped it
  2026-09-02, and it then reached a Change Log entry, a `docs/06` blocker and a
  report to him as *"the intake form is live and broken"*. **The status code was
  read without reading the document that defines what that status code means on
  that route**, and the document was in the repo the whole time. Generalised:
  **before interpreting a response, check whether the endpoint documents its own
  failure modes** — an API that rejects by design looks exactly like an API that
  is missing.

So before acting on a number: say what it is a number *of*; confirm the command
actually ran and read its exit status; and check it against a second method that
cannot fail the same way — the bytes on disk, a screenshot, a hit test.

**Two simulations of 200% text are not equivalent: media-query `rem` resolves
against the browser DEFAULT font size, not the root element — measure under both
methods before declaring a reflow result.** *Pouya's convention, 2026-09-01.*
Raising the default moves the breakpoints along with the type, so the desktop
layout is never reached and nothing overflows; setting `documentElement.style
.fontSize` doubles the type and leaves the breakpoints where they were, which is
the layout the desktop nav was measured in. One of those reported **0** while the
other reported **944 px** on the same 22 pages, and the prose generalised the
zero.

⚠️ **AND THERE ARE THREE MECHANISMS, NOT TWO — the third defeats the `rem`/`em`
FAMILY, which is not the same as defeating CSS.** Measured 2026-09-01: Chrome's
**"Minimum font size"** *floors* computed font sizes instead of scaling them, so
text enlarges while `rem` keeps resolving at 16 px. A media query in `rem` does
not see it, and neither does a container query — `@container` `rem`/`em` DO track
the root element (that is the one real difference from `@media`, and it is
measured), but under a minimum-font-size setting they still resolve at 16 px while
`getComputedStyle` reports 32 px.

⚠️ **BUT "NO CSS CONDITIONAL CAN SEE IT" IS FALSE, AND ASSERTING IT COST A
CONFORMANCE FAILURE.** *Corrected 2026-09-01, same day, by `adversarial-reviewer`.*
The **font-metric** units read the *used* font size and therefore double:
**`ch`, `ex`, `cap`, `lh`, `rlh`** all respond — in property values, in `@media`
**and** in `@container` (`ch` 10.608 → 21.216 px; `@media (min-width: 100ch)`
flips). Only `rem`, `em`, `ic` and `px` are blind. The false generalisation was
written into `docs/02`, `docs/06`, `global.css` and `tokens.css`, and it was then
used as the premise for accepting a **WCAG 2.2 SC 2.4.11 (AA)** failure as
unfixable — *"the only fix is JS"*. **The lesson is the shape, not the units: "no
mechanism can X" is a claim about every mechanism, including the ones you did not
enumerate.** Test the family you did not think of before writing "none", and
prefer "every construct I measured is blind, and here is the list" — which is
falsifiable and was what the measurement actually supported.

For *reflow* the conclusion is unchanged: **used-value layout — wrapping — is
still the right mechanism**, because it needs no threshold and no fitted constant.
That path
was the worst of the three: on one grid of 22 pages × 16 widths, **219 of 352
page-widths overflowed** against root-style's **175**, and it was the only one
failing at 320 px and 1024 px. **Always state the grid with the count** — two
sweeps in that session quoted totals of 220, 330 and 352 for the same claim, and
side by side they read as contradictions rather than as different width lists.
Measure all three mechanisms; treat a clean result from one as evidence about
that one.

**And a grep that matches is not a finding until you read what it matched.**
A case-insensitive sweep for `LSO` hit `I aLSO practise`; a superlative sweep for
`leading` hit `the pLEADINGs`. Both on the same page on the same day. Print the
match with context before you believe it.

**Never name an Astro prop `as`.** `const { as = 'p' } = Astro.props` detaches
the `Props` interface from the component, and **every call site silently stops
being type-checked.** `astro check` reports it only as `ts(6196) 'Props' is
declared but never used`, which reads like lint noise. Measured: with the prop
named `as`, `<Eyebrow dot as="h9" bogusProp={1} />` compiled with **0 errors**;
renaming the one identifier to `tag` made the same probe fail correctly. **Do not
silence a `ts(6196)` with `Astro.props as Props`** — that hides the warning and
leaves the call sites unchecked, which is strictly worse. If that hint appears on
any component, pass it a bogus prop before believing its props are checked.

**A sweep is a command, not a claim.** Any statement that a change was applied
across files — a phrase removed everywhere, a path updated everywhere, a
decision swept through the docs — must cite the command that proves it, and be
written only after reading that command's output. Paste the `grep` into the
Change Log entry. Three consecutive entries on this project asserted a completed
sweep; instances survived all three, and one of them was inside
`.claude/agents/claims-auditor.md` — the definition of the agent whose job is to
catch exactly that. Recall is not evidence.

**And sweep the VOCABULARY, not only the subject.** *Added 2026-08-30, from the
Q.Arb amendment.* `git grep 'Q.Arb'` is line-anchored, so it could not find **ten
lines in `docs/03` that were entirely about Q.Arb and never named it** — an
unstruck, imperative block still instructing the struck form, eleven lines below
that change set's own strike notice on the same bullet. The sweep was a real
command and its output was read honestly. It was still the wrong command.

So after sweeping the term, sweep the words its claims are **made of** — here,
the stage vocabulary (`commenced`, `in progress`, `pathway`, `not yet`) with no
mention of the designation. This is R8's sharpest edge, and it is the one that
survives an honest reader: a sweep can pass every test in the rule above and
still miss everything, because the anchor you chose is not the anchor the text
uses. The same session also excluded `docs/reference/` as "sourced extracts" —
half right. The quotations there are evidence; **the commentary around them is
this repository's voice**, and three lines of it still asserted the struck row.


**`check:claims` IS FROZEN. It is a tripwire, not a program.** *Pouya's ruling,
2026-08-30.* Round 2 of the Q.Arb amendment found **five defects in round 1's own
fixes to that script, two of which made it worse than before the pattern
existed** — a dedup key that reported two breaches of the same string as one (the
check truncating its own output), and a collapsed-text view whose window leapt
paragraph boundaries onto approved copy while its comment claimed it could not.
At that point it was generating defects at roughly the rate it caught them.

The rule, and it has no exceptions:

- **A pattern is added only after a real breach has reached `dist/`.** Never
  speculatively, never to close a gap you can imagine.
- **Each addition ships with a probe** — an injected page proving it catches the
  actual breach — **and a negative fixture** proving it stays silent on the
  approved copy nearest to it.
- **No refactors. No coverage improvements. No tidying.** If a pattern is wrong,
  change that pattern deliberately, with a Change Log entry. Do not rewrite the
  scanner around it.

Under D20 this script is the only per-step claims control, which is an argument
for keeping it **correct**, not for growing it. It catches the §4 breaches that
are greppable and makes no claim about the ones that are not.

**Comments record decisions, not history — D19.** *"X because D13"* stays.
*"This was Y, then flagged, then became X"* belongs in the `AGENTS.md` Change
Log, which is where a reader looks for how something got here. **A comment
longer than the code it explains must justify itself. Trim on sight.**

Pouya's ruling, 2026-08-28, on his own measurement: **342 lines added to `src/`
in one session for 8 functional lines**, and four of that session's review
findings were stale statements living inside those comments. A comment that
narrates its own revision history becomes a second record to keep true, and then
a source of defects about the record rather than about the site.

This does **not** license deleting a comment that carries a live constraint. The
parent-scope trap, the `animation-timeline` minifier defect and the `as`-prop
hazard above are load-bearing and stay. The test is whether a future reader needs
it **to avoid breaking something** — not whether it is interesting.

**Commits.** Conventional Commits (`feat:`, `fix:`, `docs:`, `chore:`, `refactor:`).
One logical change per commit. Never commit secrets, `.env` files, or AWS
credentials. Gitea is not an AWS OIDC provider, so the deploy key is designed as
a static IAM access key to be held in Gitea Actions secrets — whether it has
actually been provisioned is `AGENTS.md` Q22. It must never reach the repo.

**Performance budget.** Lighthouse ≥ 95 on all four categories, on mobile, for
every page. Under 100 KB of JS on any route. LCP under 2.0 s on a simulated
Slow 4G connection. Treat a budget breach as a failing build.

**Lighthouse runs again as of 2026-08-31 — `npm run lighthouse`, and it is
`lighthouse` rather than `@lhci/cli`.** It enumerates every `index.html` in
`dist/`, so the page set cannot go stale; it asserts the four category scores and
**reports** LCP and CLS without asserting them, because simulated throttling on a
loopback server is not the Slow 4G field measurement `docs/04` describes.

**It is a LOCAL gate, not a CI check.** Standalone Lighthouse drives an installed
browser and the Gitea runner has none. So it is `npm run lighthouse` at a
keyboard plus a blocking item on `docs/06`'s cutover checklist, and it is
deliberately not wired into `npm run build` or either deploy path. Do not
describe it as gating a deploy.

**Two things about the numbers, and both have to travel with them.** The
accessibility category is measured with `prefers-reduced-motion` **forced** —
otherwise axe's `color-contrast` audit reads the scroll-driven reveal's
mid-animation opacity and reports 24 false nodes (measured; `#d0cbc4` on
`#f8f4ed`, neither of which is in this palette). And the reason it is
`lighthouse` and not `@lhci/cli` is that `AGENTS.md` §7's advisory attribution
was **wrong**: the carriers were `@lhci/cli`'s own `tmp` and `@puppeteer/browsers`'
`extract-zip`, not Lighthouse, and `lighthouse@13.4.1` audits clean. The budget
was unmeasurable for five days on a cause nobody re-derived — which is the same
lesson from the other side: **a documented control that no longer exists is
precisely the defect Q22 turned out to be**, and so is one recorded as impossible
on a reason that was never re-tested.

## What "done" means for a page

- [ ] Copy written from `docs/03-content-spec.md`, every claim traceable to `AGENTS.md` §4
- [ ] No `TODO(pouya)` left unlogged in §9
- [ ] Unique title, meta description, canonical, OG/Twitter tags, JSON-LD
- [ ] Semantic HTML; keyboard navigable; reduced-motion honoured
- [ ] Lighthouse ≥ 95 mobile, all four categories — `npm run lighthouse` after
      `npm run build`. Read the exit status, not the table
- [ ] Renders correctly with JavaScript disabled
- [ ] `AGENTS.md` Change Log entry appended
