+  hash) and `GET /xce/v1/presets/{name}` / `{ns}/{name}` (fetch). Every
+  authenticated user may see them.
+- **Where server presets live** (user, 2026-10-12): a directory beside the
+  apiserver's other config, `<TopDir>/config/presets/` (as
+  `config/rbac.yaml` and `config/auth.yaml`, `apiserver/cmd/main.go:144`,
+  `:152`), overridable by `presets.dir` in `app.yaml` (e.g.
+  `/etc/xce/presets`).
+  - One file per preset; site presets at the top level, team presets one
+    subdirectory deep (`cfd-team/openfoam-large.yaml`).
+  - Re-read when a file's mtime changes, no restart; a file that fails to
+    parse is skipped, logged and not listed, without affecting the others.
+  - No database, no HA. With several apiservers the directory is deployed
+    to each, like `rbac.yaml`; the content hashes in the listing let a
+    client notice a mismatch.
+  - Delegation needs no feature: `presets.dir` can be a git checkout pulled
+    by a timer, so teams change presets by pull request with history.
+  - Not in `ClusterConfig`: controller and scheduler never use presets
+    (independence rule, `config-design.md`) and presets change far more
+    often than cluster config (frequency rule); it would also turn every
+    preset edit into a cluster config upgrade.
 - **Pull copies.** `xcecli preset pull <name>` writes a complete, standalone
   local preset with an informational `origin` (server name, content hash,
   pull date). Removing or changing a server preset never affects local
   copies. `xcecli preset diff <name>` compares with the server (reports when
   it is gone); `preset pull --force` refreshes. Both are user-initiated.
+- **Name collisions on pull** (user, 2026-10-12). Namespaced presets go to
+  their subdirectory, so only the same path can collide:
+  - the local file is a pulled copy of the same server preset (its `origin`
+    matches): an update; pull shows the diff and stops, `--force` replaces
+    it;
+  - anything else (a personal preset, or a copy from another server or
+    path): pull refuses and suggests `--as <name>` (pull under another local
+    name; `origin` keeps the server name, so `diff` still works) or
+    `--force`;
+  - `--force` keeps the replaced file as `<name>.yaml.bak`;
+  - `preset pull --all [ns]` applies the same rules per preset, listing and
+    skipping collisions.
+- **Submit uses local presets only.** `--preset X` not found locally but
+  present on the server stops with "not found locally; the server has `X`:
+  run `xcecli preset pull X`". Never an automatic pull, so server changes
+  or removals never affect a submit.
 - **User-to-user sharing** without the server: `preset export` / `import`
   (file, mail, git).
 - **Site presets complement profiles.** Admins typically publish a preset

 - [ ] job-resize — NEW 2026-10-10 (from long-running services discovery; not on the services path). Grow/shrink a running parallel job's allocation (LSF resizable jobs, `bresize`) for elastic applications. Brief: `.kiro/specs/job-resize/brief.md`. Dependencies: parjob-placement, host-failure-job-recovery.
 - [ ] project-delegated-membership — NEW 2026-10-10 (from project-config requirements, user decision: future). Project managers edit their project's (and subtree's) members at runtime without an admin config push; needs a durable store that coexists with `xceadmin` config pushes (e.g. a separate delegated member list) and audit. Dependencies: project-config, rbac-persistence.
 - [ ] job-modify — NEW 2026-10-12 (from application-profile discussion, user decision; backlog, no brief yet). Modify a pending job (LSF `bmod`): apiserver action (today `"modify"` is commented out, `controllers/jobs.go:2446`; `JOB_MODIFY` only an enum), controller opcode, WAL fact with snapshot field-completeness, scheduler re-merge, xcecli. First attributes: `--app` (owner with `app:use` on the new profile; admins in bulk, e.g. `--app-from <old>`), `-R`, `-n`, queue; later begin/end time (`job-time-window`), dependencies. Dependencies: application-profile, job-config-merge.
-- [ ] xcecli-presets — NEW 2026-10-12 (from application-profile discussion, user decisions). Client-side presets replace convenience defaults in profiles: a preset is a set of job options (`--app`, `--queue`, `-R`, `-n`, env, limits) expanded by the client, a flag replacing the preset's value for that option; one file per preset (`~/.config/xce/presets/<ns>/<name>.yaml`, same layout in the apiserver's presets dir), env capture by name (`pass:`; `XCE_*` and secret-looking names excluded); the apiserver only shares admin-deployed presets read-only (`GET /api/v1/presets[/{name}]`), and `preset pull` copies one locally so server-side removal never affects users (`preset diff`, `pull --force` user-initiated); user-to-user sharing by `preset export`/`import`; presets carry no privilege and are not a configuration level; optional preset-name job label; the portal does the same expansion.

 - [ ] profile-usage-insight — NEW 2026-10-12 (from application-profile discussion, backlog; no brief yet). Per-profile report over recent jobs comparing the profile's defaults with actual use (requested vs. peak memory, CPU efficiency, OOM kills, pend time, runtime by variant) and suggesting better values for site presets (or a profile essential), e.g. "preset openfoam rusage mem 4000, p95 peak 1600 → suggest 2000" (Kubernetes VPA recommender precedent). **Advisory only** (user decision): the admin applies changes to site presets or `applications.yaml`; nothing tunes itself. Optional user hint ("used 1.4G of 4G requested"). Dependencies: application-profile, run usage in job records.
 - [ ] lsf-config-migration — NEW 2026-10-09 (user idea, backlog; no brief yet). A tool (likely an `xceadmin` subcommand) that converts LSF configuration (`lsb.queues`, `lsb.applications`, `lsb.resources` Limit sections, `lsb.users`/`lsb.hosts` groups, `lsb.params` defaults, project settings) into XCE `configs/*.yaml`, with a report of what does not map: queue `RES_REQ` (XCE queues are policy only; move into a profile or drop), LSF's full per-section merge rules vs XCE's simplified ones, compound/alternative resreqs, unsupported parameters. Dependencies: job-config-merge, application-profile, project-config, parjob-placement (span), admin-config-tool. Promote via `/kiro-discovery` when those land.
