feat: build step 4 — /mediation/, /arbitration/, /med-arb/; source ADRIC's rules

Three pages, five in the build, zero JavaScript. /arbitration/ carries §4's
paired-disclosure condition on four surfaces and Q39's struck universal appears
in no form. /med-arb/ meets the procedural-fairness objection at the level of
process design and ships deliberately without Pouya's own protocol commitments,
which are Q54.

docs/01 directed the mediation page to name the "ADRIC Model Mediation Rules".
No such document exists — 0 occurrences across all four of ADRIC's rules pages
against 10 for "National Mediation Rules"; "Model" belongs to the Model Dispute
Resolution Clause inside the rules. Caught only because R14 requires the source
before the claim. docs/reference/adric-rules.md + adric-extract/ carry it, with
the digest drift measured rather than assumed: the HTML changes per request, the
text extracts are byte-stable, so the extracts are the artefact.

Four review passes, 21 defects, and the pattern was mine: I wrote the Q54 gate
into the page and then breached it four times, then round 2 found two survivors
of round 1's own fixes and one defect round 1's fix created. Also removed a
<title> naming a practised role §4 does not grant, a habitual presupposing awards
issued, and a claim about what ADRIC's rules permit that my own reference doc
says is unsupported.

Two instrument failures caught before they became conclusions: touch targets
measured over file:// with no CSS loaded (uniform 18px, including on a .btn with
a 44px floor), and a schema.org validator call that parsed nothing and returned
0 warnings for everything. Both re-run with the instrument validated first.

+# ADRIC rules and codes — the published rule sets, in ADRIC's own words
+
+**Why this file exists.** `docs/01-architecture.md` directs `/mediation/` to
+name *"ADRIC Model Mediation Rules"* and `/arbitration/` to name *"ADRIC, ADR
+Chambers, ad hoc"*. A rule set's **name** is a fact about a published document,
+so under Q46(b)'s standard it may be published — but only from a source, not
+from recall. R14: a claim whose artefact is unreachable is unverifiable by
+construction. This is the same fetch-before-writing that caught
+`Chartered Mediator-Arbitrator` (`docs/reference/adrio-designations.md`).
+
+**It caught one immediately. See Finding 1.**

+
+⚠️ **THE HTML DIGESTS DRIFT ON EVERY REQUEST. THE TEXT EXTRACTS DO NOT.**
+Unlike the ADRIO fetch, where the digests were stable and are therefore stamped
+as the artefact, these pages change per response. **Measured, not assumed** — the
+mediation-rules page was fetched twice, three minutes apart:
+
+```
+first : c55fe482da8aa7a69377703b9192bda0d926f012e45a90ca5ce5d27a7b0344ac
+second: e9f74014ec04e8fcab0f1cbbd75ef4cb104c8d94992b93c832d41c8259ce78b2
+text identical? YES
+```
+
+Four causes, read out of the diff rather than guessed at:
+
+1. a per-render page-builder class suffix (`highend_6a91df2f53035` →
+   `highend_6a91dfca9a8be`);
+2. a **rotating corporate-member logo carousel** in the footer — nine sponsor
+   logos, reordered per request;
+3. **Cloudflare email obfuscation**, which re-keys the `email-protection#…`
+   hash per response;
+4. a **Cloudflare challenge-platform token** (`__CF$cv$params` `r` and `t`).
+
+*(This paragraph first asserted "a WordPress nonce and rotating asset query
+strings" — a guess, written before the second fetch. None of the four causes is
+that. Corrected before commit, and recorded because a guessed cause for an
+observed difference is exactly what `CLAUDE.md` bars.)*
+
+**So the stable artefact is `docs/reference/adric-extract/`**, and the term
+counts below were run against those extracts. A digest mismatch on re-fetch is
+**not** evidence the content changed — re-extract and compare the text.
+
+Also on the record: `https://adric.ca/rules/` returns **403**, and
+`/mediation-rules/` and `/arbitration-rules/` return **404**. The working paths
+are all under `/rules-codes/`. Recorded because a 403 body is 52 bytes and reads
+like an empty page.
+
+---
+
+## Finding 1 — "ADRIC Model Mediation Rules" is NOT the name of anything
+
+`docs/01-architecture.md` §`/mediation/` item 3 directed the page to name the
+**"ADRIC Model Mediation Rules"**. The string does not exist in ADRIC's
+materials.
+
+| Term | rules-codes | national-mediation-rules | arbrules | adric-med-arb-rules |
+|---|---|---|---|---|
+| `Model Mediation Rules` | 0 | 0 | 0 | 0 |
+| `National Mediation Rules` | 2 | 10 | 2 | 2 |
+| `ADRIC Mediation Rules` | 1 | 0 | 0 | 0 |
+| `ADRIC Arbitration Rules` | 3 | 3 | 7 | 3 |
+| `ADRIC Med-Arb Rules` | 5 | 4 | 4 | 9 |
+
+**Where "Model" actually belongs.** ADRIC publishes a **Model Dispute Resolution
+Clause** — a contract clause, inside the rules document. The spec's phrase
+conflates the clause's name with the rules' name.
+
+**The canonical title, from the page's own heading:** *"The ADRIC National
+Mediation Rules"*. The Model Clause it publishes uses the same form —
+*"shall be mediated pursuant to the **National Mediation Rules** of the ADR
+Institute of Canada, Inc."*
+
+**One inconsistency in ADRIC's own materials, recorded so it is not read later
+as our error.** The `/rules-codes/` index has a card labelled *"ADRIC Mediation
+Rules"* (1 occurrence, card link text) while its nav and the document itself say
+*"National Mediation Rules"*. **Use `ADRIC National Mediation Rules`** — the
+document's own title, and the form inside the model clause.
+
+## Finding 2 — the three rule sets, with the facts a page may state
+
+**ADRIC National Mediation Rules.** *"The National Mediation Rules provide rules
+for initiating mediations, including the appointment of a mediator should the
+parties be unable to come to an agreement."* The document contains: Mediation
+Rules including a Code of Conduct; a Standard Form Agreement to Mediate
+(Schedule B); ADRIC administration fees (Schedule A); and the Model Dispute
+Resolution Clause.
+
+⚠️ **Currency caveat, verbatim:** *"As of 2025, the ADRIC Mediation Committee is
+currently reviewing the Mediation Rules… In the meantime, the existing rules
+remain in effect and should continue to be used until any updates are formally
+adopted."* So do not date them, and do not describe them as recently revised.
+
+**ADRIC Arbitration Rules.** *"ADRIC has adopted new Arbitration Rules and a new
+Arbitrator Appointment Protocol, effective March 1, 2025."* Published as
+**"ADRIC Arbitration Rules – Effective 2025"**, alongside an **ADRIC Arbitrator
+Appointment Protocol** and named forms: Notice to Arbitrate, Request to
+Administer the Arbitration, Request for the appointment of an arbitrator,
+Application for Urgent Interim Measures, Application to Challenge an Arbitrator,
+Notice of Appeal.
+
+**ADRIC Med-Arb Rules.** A discussion draft was presented to the membership at
+ADRIC's Annual Conference in **November 2019**. Two sentences are directly
+useful to `/med-arb/`, both verbatim:
+
+> "Med-Arb is not merely the merging of separate mediation and arbitration
+> processes, but a unique process designed to meet the needs of particular
+> disputants. It involves nuances and complexities that can be fine-tuned to the
+> needs of the parties as a customized dispute resolution process, **which
+> requires a high level of practitioner competence to do successfully**."
+
+> "The Rules are designed to work in tandem with ADRIC's existing Mediation
+> Rules and Arbitration Rules, integrating seamlessly."
+
+**Scope, verbatim:** *"Although the Med-Arb Rules were drafted to assist in
+resolving domestic **commercial** disputes, parties may want to apply them to
+international or non-commercial disputes."* That matches §4's commercial scoping
+without being cited for it — it is ADRIC's statement about its own rules, not
+authority for what this practice offers.
+
+ADRIC also publishes a **Med-Arb Foundational Course** (in English) and, per this
+page, *"criteria for a specialized designation: the Chartered Med-Arb"*.
+
+## Finding 3 — "Chartered Med-Arbitrator" is corroborated by a second body
+
+`Chartered Med-Arbitrator` appears **2 times on every one of the four pages** —
+it is ADRIC's own navigation label, under *Designations & CEE → Professional
+Designations*. So the long form §11 now carries, sourced from **ADRIO**, is
+independently the form **ADRIC** uses in its nav. The body prose on the Med-Arb
+Rules page uses the short *"Chartered Med-Arb"*
+**once** — *"criteria for a specialized designation: the Chartered Med-Arb"*.
+
+⚠️ *This read "3 occurrences" for one pass. `grep -o -F 'Chartered Med-Arb'`
+does return 3, but **two of the three are substrings of the nav label
+"Chartered Med-Arbitrator"** counted separately one sentence above. `grep -o
+'Chartered Med-Arb(?!itrator)'` returns 1. That is `CLAUDE.md`'s "a grep that
+matches is not a finding until you read what it matched", committed inside the
+document whose whole purpose is sourced counts. Found by
+`adversarial-reviewer`.* **Neither body writes "Mediator-Arbitrator" anywhere in this
+fetch.**
+
+## Finding 4 — what is NOT in this fetch, and must not be inferred from it
+
+- **The rules' actual provisions.** Every page above is a *landing page*; the
+  rules themselves are PDFs behind download links and were **not** fetched. So
+  this file supports naming a rule set and describing what a document contains
+  at the level its own landing page describes it. It supports **no statement of
+  what any rule requires, permits or provides** — including anything about
+  consent mechanics, caucus information, or the switch from mediation to
+  arbitration in med-arb. Write those as this practice's own protocol, or not at
+  all.
+- **Anything about ADR Chambers.** `docs/01` §`/arbitration/` names it as a rule
+  option. It is not sourced here. `docs/07-fees.md` cites ADR Chambers only for
+  *published fee ranges*, which is a different claim.
+- **Legal effect.** Nothing here establishes the enforceability of an award, in
+  Ontario or anywhere. §4 bars this repository from concluding a proposition of
+  law.
+
+## Finding 5 — ADRIC superlatives deliberately NOT lifted
+
+Same treatment as `adrio-designations.md` Finding 5. These are ADRIC's marketing
+claims about itself and **must not travel onto this site**, where §4 Forbidden
+bars superlatives:
+
+- *"The ADRIC Arbitration Rules have been **the leading choice** for Canadian
+  businesses since 2002."*
+- *"integrating **seamlessly**"* — quoted above inside a quotation, and it stays
+  inside one.
