+## Background
+
+The initial profile registry added `[alias]` as a convenience layer for redirecting one profile name to another. In practice this adds name-resolution complexity without a clear use case. It already caused bugs around source-local alias resolution and defaults pointing at aliases.
+
+Profile selection should stay simple: a registry contains profile entries and an optional default that points directly at one profile entry. If users want a short or stable name, they can choose that name as the profile registry key.
+
+There is no compatibility requirement for aliases because the feature has just landed and has not become a stable user-facing contract.
+
+## Requirements
+
+- Remove profile alias support from registry parsing and selection.
+  - Delete `ProfileAlias` and alias maps/resolution paths.
+  - Remove `[alias]` from the `profiles.toml` schema.
+  - Do not support alias-to-alias or alias-to-profile indirection.
+- Keep profile registry semantics simple.
+  - Supported schema:
+    ```toml
+    default = "coder"
+
+    [profile]
+    coder = "profiles/coder.nix"
+    researcher = "profiles/researcher.nix"
+    ```
+  - Table form may remain:
+    ```toml
+    [profile.coder]
+    path = "profiles/coder.nix"
+    description = "Coding profile"
+    ```
+  - `default` must name a profile entry directly.
+  - Unqualified defaults resolve within the declaring source.
+  - Source-qualified defaults such as `user:coder` may remain if already implemented and useful.
+- Keep existing selector behavior for real profiles.
+  - explicit path / `path:<path>`
+  - discovered unqualified names
+  - `default`
+  - source-qualified names such as `project:coder`
+  - ambiguity fail-closed
+  - TUI manifest-cascade opt-out
+- Update docs and tests.
+  - Remove alias examples and alias-specific tests.
+  - Add/keep coverage proving default points directly at a profile entry.
+  - Diagnostics for a missing default target should mention the missing profile, not alias behavior.
+
+## Acceptance criteria
+
+- `profiles.toml` no longer accepts or documents `[alias]` as a supported feature.
+- `ProfileRegistry` has no alias state or alias resolution path.
+- Existing CLI/TUI profile selection works with direct profile entries and defaults.
+- Ambiguous unqualified real profile names still fail closed.
+- Docs describe only entries + default.
+- Focused manifest/tui/pod/client profile tests pass.
+- `cargo fmt --check`
+- Relevant checks pass.
