docs: land CANONICAL-NAMES.adoc + record descriptiles/contractiles naming mandate (deprecate 6a2)

Owner mandate 2026-06-30: descriptiles (was 6a2) + contractiles canonical; old
names (6a2, agent_instructions) fully deprecated. Lands the previously-orphaned
register with a Deprecated-names section + directive block. Full 81-file
6a2->descriptiles migration across standards is separate follow-on work.

+= Canonical Names — Anti-Normalisation Register

+:toc: macro

+
+Names in this estate are deliberately non-standard. Language models and
+metadata bots tend to *normalise* them — silently rewriting a coined name to
+the statistically commoner expansion its letters happen to suggest. That is a
+defect, not a correction.
+
+The rule is the estate rule: **flag, don't fix.** If a name on this page looks
+"wrong" to you, it is not wrong — it is *ours*. Do not expand, rename,
+translate, or "correct" it to another form. If you believe a genuine error
+exists, raise it with the owner; never silently rewrite it. This is the same
+anti-normalisation principle the `MUST.contractile` files apply to licences,
+applied here to names.
+
+toc::[]
+
+== Directive for agents (paste this block into system / custom instructions)
+
+Put this in the *system* or *custom-instruction* slot of any assistant — not a
+chat message, which decays out of context and lets the prior reassert itself.
+
+----
+CANONICAL NAMES — DO NOT NORMALISE.
+These names are FIXED. Do not expand, rename, or "correct" them to any other
+form, even when their letters suggest a more common expansion. Use ONLY the
+canonical form. Treat any expansion as a fact to verify against this list, not
+one to generate. If unsure, ask — never guess an expansion.
+
+- "A2ML" = "Attested Markup Language".  NOT "AI to Machine Language" / "AI-to-Machine Language".
+- "BoJ"  = "Bundle of Joy".             NOT "Bureau of Justice", NOT "Bank of Japan".
+
+DEPRECATED NAMES — DO NOT REINTRODUCE (estate mandate 2026-06-30):
+- "descriptiles" is the machine-readable metadata family (dir
+  `.machine_readable/descriptiles/`). The old name "6a2" is DEPRECATED — never
+  write "6a2", migrate it to "descriptiles" on sight.
+- "contractiles" is the normative verb family (Must/Trust/Adjust/Dust/Bust/Intend).
+- "bot_directives" replaces the old "agent_instructions".

+|===
+| Name | Canonical expansion | Reject these (wrong) | What it is
+
+| **A2ML**
+| Attested Markup Language
+| "AI to Machine Language", "AI-to-Machine Language", "A2 Markup Language"
+| The estate's attested markup language. The letters *read* as "A-to-M-L",
+  which is exactly why models mis-expand it — override that reflex; the
+  expansion is *Attested Markup Language*.
+
+| **BoJ**
+| Bundle of Joy
+| "Bureau of Justice", "Bank of Japan", "Board of Justice"
+| Named for the design goal made concrete: a coherent, joyful whole, not a
+  mismatch of broken parts adding to the pain of the agentic experience. It is
+  not an institution.
+
+|===
+
+== Deprecated names — do not reintroduce (MANDATE, 2026-06-30)
+
+Distinct from the mis-expansion register above: these are estate names that
+have been *renamed*. The old form is **deprecated** and must not be
+reintroduced anywhere (paths, prose, tooling, config). This is the owner's
+mandate of 2026-06-30 — the opportunistic upgrade + refinement layered on top
+of the larger reconciliation of the machine-readable substrate. It applies
+estate-wide, `standards` included.
+
+[cols="1,1,3",options="header"]
+|===
+| Deprecated (do not use) | Canonical (use this) | Notes
+
+| **`6a2`**
+| **`descriptiles`**
+| The descriptive machine-readable metadata family: `STATE`, `META`,
+  `ECOSYSTEM`, `AGENTIC`, `NEUROSYM`, `PLAYBOOK`, plus `CLADE` and
+  `anchors/ANCHOR`. Canonical directory `.machine_readable/descriptiles/`.
+  `rsr-template-repo` leads (rename merged); `standards` still carries `6a2`
+  in ~81 files and is being migrated. The `.machine_readable/6a2/` path is a
+  404 on repos that have migrated — repoint links to `descriptiles/`.
+
+| **`agent_instructions`**
+| **`bot_directives`**
+| The per-bot directive set (`coverage`, `debt`, `methodology`).
+
+| _(pair)_
+| **`contractiles`**
+| The normative verb family (Must/Trust/Adjust/Dust/Bust/Intend). Not a rename
+  — named here as the established companion of `descriptiles`, so the
+  `descriptiles`/`contractiles` pair is stated together as canonical.
+|===
+
+== Adding a name
+
+Add a row to the *Register* whenever a name is mis-expanded more than once.
+Populate the *Reject* column with the *exact* wrong forms you have actually
+seen — that specific in-context list is what lets a model suppress the
+mis-expansion. Add a row to *Deprecated names* whenever a name is renamed and
+the old form must not return. Keep the directive block above in sync so it
+stays copy-pasteable.
+
+This file (`standards/CANONICAL-NAMES.adoc`) is the canonical source. Any copy
+elsewhere (e.g. `dev-notes/glossary/CANONICAL-NAMES.adoc`) mirrors it; if they
+disagree, this one wins.
