--- name: ARC link treatment — one rule, two named exceptions description: Predictability principle for ARC link styling — single global treatment per spec §VII.c, with avatar-link and Reading Compass as the only exempt elements type: feedback originSessionId: 8d9ac240-47df-4578-aec1-a9dd32965027 permalink: claude-memory/feedback-arc-link-treatment-one-rule-two-exceptions --- ARC link treatment follows **one rule, two named exceptions** — captured by steward 2026-05-02 during the §VII.c link-spec drafting + SCSS migration session. > *"the avatar and reading compass are the only links that need special treatment. The rest should be predictable and crafted with care"* **Why:** Predictability is the principle. A reader's eye trained by reading one ARC piece should know what a link looks like in any other. Multiple competing link treatments across contexts (catalogue/wholeform variant, apparatus quiet-nav variant, button variant, etc.) fragment the reader's intuition and require re-learning per page. The discipline of one treatment is also the discipline of care — every link gets the same considered typography rather than ad-hoc per-context decisions. **How to apply:** - The TWO exceptions are documented in spec §VII.c "Exceptions" subsection: 1. **`.avatar-link`** — wordmark in page header; underline would compete with wordmark typography 2. **Reading Compass** (per §VI) — eight-sigil navigation; underline would be redundant beneath glyphs - Everything else (in-text, apparatus, catalogues, navigation) follows §VII.c (Pompeian-red hair-thin underline, body-color text, native `text-decoration` per Rutter / Bringhurst transferred). - When you encounter a context-specific link rule that diverges from §VII.c, the question is NOT *"is this a different valid pattern?"* but rather *"is this (a) legacy material destined for an archival collection where preservation overrides current-spec alignment, or (b) a cascade artifact to be reconciled?"* Don't propose new sub-spec sections for the divergence; reconcile it or archive it. - The earlier impulse (mine, 2026-05-02) to spec multiple sub-variants (§VII.c.ii catalogue, §VII.c.iii quiet-nav, §VII.c.iv button) was over-elaboration. Resist that pattern. The simpler frame — *one rule, two exceptions, everything else predictable* — is correct. **Related:** care-over-traffic (work answers to itself; quality + predictability + accountability matter even at low traffic); the broader "would Alexander do it like this?" discipline against unnecessary elaboration.
