+### Disambiguate user-facing names from system ids (issue #128)
+
+Realizes the cluster-`identity` foundation ([plan](docs/plans/identity-id-name-disambiguation.md)): the three identity-carrying entities — **experiment**, **worker**, **group** — stop conflating system identifier with operator-facing label. Their ids become **opaque, system-minted, immutable** (`exp_*` / `wkr_*` / `grp_*`, a type-prefix + 26-char lowercase Crockford-base32 ULID), and each gains an OPTIONAL operator-supplied **display name**. Reserved values move from id-space to name-space. One atomic rename across spec, schemas, contracts, storage, wire, control-plane, services, web-ui, setup, docs, and conformance. Pre-external-user clean break — no compat shims, no migration tooling; existing experiments are re-bootstrapped. Strict prereq for [#140](https://github.com/ealt/eden/issues/140) / [#141](https://github.com/ealt/eden/issues/141) / [#143](https://github.com/ealt/eden/issues/143) / [#144](https://github.com/ealt/eden/issues/144).
+
+**Spec (canonical grammar in one place).** [`02-data-model.md`](spec/v0/02-data-model.md) gains §1.6 "Opaque entity identifiers" (the `exp_`/`wkr_`/`grp_` grammar + the composite *actor* `admin|wkr_*` and *member* `wkr_*|grp_*` shapes) and §1.7 "Display names" (1–128 NFC code points, no control chars). §2.5 (experiment runtime), §6 (worker), §7 (group) carry the opaque-id + optional-`name` split; reserved values are now reserved **names** (worker: `admin`/`system`/`internal`; group: `admins`/`orchestrators`). Chapters 01/03/04/05/07/08/09/10/11 defer to §1.6/§1.7 (no restated grammar). Bearer principal grammar is `admin`|`wkr_*` (§13). Register endpoints (§6/§7, §15) drop the caller-supplied id, take optional `name`, and the server mints the id; new `?name=` lookups (0..N). Checkpoint import (§14.2, [`10-checkpoints.md`](spec/v0/10-checkpoints.md) §10) is a normative behavior change: without an `as_experiment_id` override the receiver lands the import under its own minted id and stamps `imported_from.source_experiment_id` for provenance rather than reusing the source id.
+
+**Schemas + contracts.** All JSON Schemas (core + `wire/`) updated in lockstep with the Pydantic `eden-contracts` models; `_common.py` defines `ExperimentId`/`WorkerId`/`GroupId`/`ActorId`/`MemberId`/`DisplayName` + a pure-Python Crockford-base32 ULID minter (`mint_opaque_id`), and a `display-name` `FormatChecker` keeps schema↔model parity over the corpus (legacy kebab fixtures removed; opaque accept/reject fixtures added). `ImportProvenance` gains `source_experiment_id`.
+
+**Storage + wire + services.** `register_worker(name?, …)` / `register_group(name?, …)` / control-plane `register_experiment(config_uri, name?)` MINT opaque ids (no id-based idempotency — restart recovery uses the persisted id + `reissue_credential`); reserved-name guard with an `allow_reserved` seed seam (the deployment-admin bearer creates the reserved groups); `name TEXT` columns + indexes (storage migration v7) on SQLite + Postgres + the control-plane registries; `list_workers(name?)`/`list_groups(name?)` filters; new `InvalidName` error → 422 `eden://error/invalid-name`. Wire register endpoints mint+return ids and resolve authority groups by reserved name to their `grp_*` id; `StoreClient.whoami()` returns `{worker_id, name}`. `setup-experiment.sh` is the sole minter of per-experiment infra workers — it mints `exp_*`/`wkr_*`/`grp_*`, writes ids to `.env` + tokens to the credentials dir, and is idempotent-on-re-run via `.env`; `.env.example` becomes a generated minted-id artifact; compose overlays + healthcheck smokes resolve ids from `.env` / `?name=` / opaque-id URLs.
+
+**Web UI.** Registration forms POST a `name`; the server mints the id; list/detail views render `<name> (<id>)` (bare id when unnamed; logs/events use the id only) with a name-search box; the `/admin` gate resolves the `admins` group by reserved name.
+
+**Conformance.** The harness mints `exp_*` per scenario and resolves stable display-name handles → minted ids transparently (`wire_client.worker_id_for`/`group_id_for`/`member_ref`); scenarios register-then-use, assert reserved-value rejection in name-space, assert the checkpoint `source_experiment_id` provenance, and cite the canonical §1.6/§7.5 MUSTs (citation-checker green).
+
+**Deferred (tracked):**

+- *Name uniqueness / collision soft-check* — names MAY collide by design; a slug-style warn-on-collision is a polish follow-up. Filed as [#275](https://github.com/ealt/eden/issues/275).

 ### Per-route store swapping for the experiment switcher (issue #145)
 
 Closes the Phase 12c §3.6 deferral: the cross-experiment switcher shipped in 12c (the `/admin/experiments/` dashboard, the `Session.selected_experiment_id` cookie field, and `POST /admin/experiments/{E}/select`) recorded the operator's selection but every per-experiment route still read the startup-bound `app.state.store` / `experiment_id` / `experiment_config`, so "select experiment Y" only relabelled the page. This chunk makes the selection load-bearing: every per-experiment web-ui route now resolves the active experiment per-request and operates against its store / config / repo. Reference-impl web-ui only — **no spec / wire / JSON-schema / Pydantic / conformance change** (Decision 10/11; per-route swapping is web-ui behavior with no observable signal at the chapter-9 §6 IUT contract).
