 ## Background
 
-This work item was migrated from an unfinished TODO.md entry that did not have a dedicated legacy ticket file.
+This work item was migrated from an unfinished TODO.md entry:
+
+> 事前定義したManifestをProfile的に扱い、Orchestrator/Coder/Researcherで別々のモデル/設定を使わせる運用ができるようにする
+
+The current manifest cascade is good at configuration defaults by location: built-in defaults, user manifest, workspace manifest, and explicit overlays. That is less suitable for operational role selection. Users want to choose between profiles such as Orchestrator, Coder, Researcher, Reviewer, or cheap/fast variants, and they want those profiles to be portable as a pure artifact rather than assembled implicitly from several ambient layers.
+
+Another problem is authoring ergonomics. The current manifest exposes many low-level numeric parameters that require implementation-specific intuition, such as compaction thresholds, pruning protection sizes, memory thresholds, and feature-specific token limits. Profiles should let users express high-level intent and reusable presets while the resolver produces the precise runtime manifest.
+
+## Related work
+
+- `work-items/open/20260529-145355-manifest-profile-encrypted-secrets/item.md`: profiles should integrate with explicit encrypted secret references so API keys/tokens are not limited to process environment variables.
+
+## Design direction
+
+Use Nix as the default human-authored profile format. A profile is a Nix expression that produces the final Pod manifest/configuration artifact through an Insomnia-provided `mkProfile` / `mkManifest` style library.
+
+The profile itself is the source of truth. Commonality, imports, role presets, and any cascade-like behavior should be expressed in Nix by the profile author instead of being implemented as an additional ambient manifest cascade in Insomnia.
+
+The runtime boundary should be:
+
+```text
+selected Nix profile + explicit startup inputs
+  => deterministic resolved manifest/config snapshot
+  => Pod runtime
+```
+
+Do not introduce a three-layer authoring model where Nix generates TOML profiles that then merge into TOML manifests. That would make manifest/profile/Nix ownership unclear and hard to operate. Rust should consume the resolved artifact, ideally as a typed JSON/config representation, and preserve a snapshot for Pod restore.
+
+## Requirements
+
+- Add a Nix-based profile entrypoint as the default path for new Pod creation.
+  - Provide an Insomnia Nix library with `mkProfile` / `mkManifest` helpers.
+  - The helper should produce a pure resolved manifest/config artifact that Rust can deserialize and validate.
+  - Profile authors may use Nix imports/functions to share common settings, implement their own cascade, or build role presets.
+- Treat the resolved manifest/config as the runtime contract.
+  - Persist the selected profile identity/source and the resolved snapshot in Pod/session metadata.
+  - Pod resume should prefer the saved resolved snapshot, not silently re-evaluate the Nix profile.
+  - Re-evaluating a profile for an existing Pod must be explicit because it may change model, tools, permissions, or thresholds.
+- Move role-oriented authoring into profiles.
+  - Support profiles for roles such as Orchestrator, Coder, Researcher, Reviewer, and cost/performance variants.
+  - Profiles should be able to select model/provider settings, prompts, tools, permissions, memory behavior, web/search behavior, workflows, skills, and context/compaction strategy.
+  - Prefer semantic presets in the Nix library for values that are difficult to tune by raw numbers, e.g. context budget, compaction behavior, retention, autonomy, and tool policy.
+  - Keep raw low-level numeric overrides available as an advanced escape hatch, not the primary user-facing interface.
+- Shrink ambient cascade to discovery/default selection rather than runtime config merging.
+  - User/project configuration may provide profile registries, aliases, defaults, and UI preferences.
+  - User/project configuration should not be required as intermediate runtime override layers for model IDs, compaction thresholds, or other behavior controlled by the selected profile.
+  - Existing TOML manifest cascade can remain as compatibility/debug/test infrastructure, but it should not be the main profile design.
+- Add profile discovery and selection UX.
+  - New Pod creation UI should show a selectable profile field such as `profile: coder (default)`.
+  - The profile picker should list built-in/user/project/explicit profiles with enough source/default information to avoid ambiguity.
+  - CLI/TUI should support explicit profile selection by name/source and by path/flakeref where appropriate.
+  - Ambiguous profile names should fail closed or require source-qualified selection rather than being implicitly merged.
+- Keep secrets as references, not plaintext values.
+  - Nix profiles may refer to credentials using typed secret references, e.g. `secrets.ref "brave.search.default"`.
+  - Nix evaluation output, resolved config serialization, diagnostics, session logs, and model context must not contain plaintext secrets.
+  - Secret dereferencing/decryption happens in Rust at the consumer boundary.
+- Define compatibility and fallback behavior.
+  - `--manifest` / TOML manifest loading may continue to work for compatibility, tests, fixtures, and low-level debugging.
+  - If Nix is unavailable, diagnostics should clearly say that profile resolution requires Nix and point to the manifest/resolved-config fallback path.
+  - Existing manifest behavior should not be broken until the Nix profile path is implemented and documented.
+
+## Open design points
+
+- Exact Nix entrypoint shape:
+  - flake output names, e.g. `insomniaProfiles.<name>` / `profiles.<name>`
+  - path-based profiles, e.g. `.insomnia/profiles/coder/profile.nix`
+  - whether both are supported initially
+- Exact Rust-facing artifact:
+  - JSON resolved config vs TOML manifest snapshot vs a new typed `ResolvedPodConfig`
+  - whether `PodManifest` remains the final runtime type or becomes the legacy/compatibility representation
+- Profile registry/default storage:
+  - where user-level profile aliases live
+  - where project-level defaults live
+  - how built-in profiles are exposed
+- How much Nix support is external-command based initially vs embedded/library-integrated later.
+- How profile summaries are generated for the new Pod UI without exposing low-level internals or secrets.
 
 ## Acceptance criteria
 
-- Define the concrete requirements before implementation.
+- A Nix profile can be selected when creating a new Pod and resolves to the complete runtime manifest/config for that Pod.
+- Insomnia provides a documented `mkProfile` / `mkManifest` Nix helper for producing a valid resolved profile artifact.
+- Profile authors can share common settings and implement cascade-like composition in Nix without relying on ambient user/project manifest merging.
+- New Pod UI includes profile selection and displays the effective default, e.g. `profile: coder (default)`.
+- CLI/TUI profile selection supports at least one explicit path/flakeref flow and one discovered-name/default flow.
+- Resolved profile artifacts are validated with clear diagnostics before Pod creation.
+- Pod/session metadata persists the selected profile identity/source and the resolved snapshot.
+- Pod resume uses the persisted resolved snapshot unless the user explicitly asks to reload/re-resolve the profile.
+- Secret references are preserved as references through Nix evaluation and resolved config; plaintext secrets are not written to config snapshots, logs, diagnostics, or model context.
+- Existing TOML manifest path remains available as a compatibility/debug/test path during the migration.
+- Documentation explains the new profile model, why ambient cascade is no longer the primary runtime config mechanism, and how users should structure reusable Nix profiles.
+- Focused tests cover Nix profile resolution, validation errors, profile default/source selection, ambiguity handling, snapshot persistence, and no-plaintext secret serialization paths.
+- `cargo fmt --check`
+- Relevant manifest/profile/pod/tui tests pass.

-## Background
-
-Insomnia currently has strong local filesystem / shell / memory tools, but the agent cannot directly consult current web information except through user-provided excerpts or shell commands. Add first-class WebSearch and WebFetch tools so the model can gather public web information through bounded, observable tool calls.
-
-This should be implemented as normal built-in tools, not as hidden context injection. Tool calls and results must remain visible in history, subject to manifest permission policy, and bounded by output limits.
-
-## Requirement
-
-- Add `WebSearch` tool.
-  - Input includes query string and optional result limit.
-  - Output returns structured results: title, URL, snippet/summary, source/search provider metadata where available.
-  - Search provider must be configurable. If no provider/API key is configured, the tool should fail with a clear diagnostic instead of falling back to scraping arbitrary search pages.
-- Add `WebFetch` tool.
-  - Input includes URL and optional mode/limits.
-  - Output returns normalized text content plus metadata such as final URL, status, content type, title if available, and byte/token truncation indication.
-  - HTML should be converted to readable text. Non-text content should be rejected or summarized only when a safe explicit handler exists.
-- Add manifest configuration for web tools.
-  - Enable/disable controls.
-  - Search provider/API key configuration.
-  - Fetch timeout, max response bytes, max output bytes/tokens, redirect limit.
-  - Allowed/denied URL schemes and host policy.
-- Integrate with built-in tool registration and manifest permission policy.
-  - Web tools are normal tool calls and should go through the existing tool permission mechanism.
-  - No implicit network access should happen outside a tool call.
-- Add security and reliability protections.
-  - Only `http`/`https` by default.
-  - Reject local/private/link-local/loopback addresses by default unless explicitly configured.
-  - Bound redirects and re-check final URLs.
-  - Bound download size and output size.
-  - Provide clear errors for timeout, DNS/network failure, unsupported content, blocked host/scheme, and truncation.
-- Prompts/tool descriptions should tell the model when to use WebSearch vs WebFetch and that fetched content may be stale/untrusted.
-
-## Acceptance criteria
-
-- `WebSearch` and `WebFetch` are registered built-in tools when enabled/configured.
-- Tool schemas are typed and validated.
-- Manifest docs/config examples describe how to enable/configure web tools.
-- Permission policy can allow/deny/ask these tools like other tools.
-- Tool results are bounded and visible in history; no hidden web context is injected.
-- Unit tests cover input validation, disabled/unconfigured errors, URL policy, redirect/final URL policy, output truncation, and representative HTML-to-text conversion.
-- At least one integration-style test uses a local test HTTP server or mock provider rather than the public internet.
-- `cargo fmt --check`
-- `cargo check -p tools -p manifest -p pod`
-- Relevant focused tests for tools/manifest.
-
-## Out of scope
-
-- Browser automation.
-- Authenticated browsing / cookies / sessions.
-- Javascript rendering.
-- File downloads as attachments.
-- Using arbitrary shell commands as the primary web access path.
-- Hidden pre-request browsing or automatic web context injection.

+## Background
+
+WebSearch/WebFetch made API keys more visible as a UX problem: `WebSearch` currently expects `web.search.api_key_env`, so users must export `BRAVE_SEARCH_API_KEY` before starting the Pod/TUI process. That is inconvenient for long-lived Pods, profile switching, and per-project/provider configuration.
+
+This should not be solved by adding `.env` loading as an implicit side effect. `.env` files are easy to leak into projects, do not solve profile-specific credential selection cleanly, and still expose secrets through process environments. Instead, when manifest profiles are designed/implemented, add a first-class encrypted secret store that manifests/profiles can reference.
+
+Related work item: `work-items/open/20260527-000022-manifest-profiles/item.md`.
+
+## Requirements
+
+- Design a typed secret reference format for manifest/profile fields that need credentials.
+  - Existing env references such as `api_key_env = "BRAVE_SEARCH_API_KEY"` should keep working.
+  - Add a new encrypted-store reference form, e.g. `api_key_secret = "brave.search.default"` or a more general `SecretRef` enum.
+  - Secret references must be explicit in resolved config; do not silently read arbitrary `.env` files.
+- Add an encrypted local secret store suitable for API keys/tokens.
+  - Store secrets outside tracked project files by default, under the user data/config directory.
+  - Use authenticated encryption and atomic writes.
+  - Do not log plaintext secrets, include them in session logs, expose them to model context, or return them through normal tool output.
+  - Keep encrypted blobs out of git-managed work-items/memory/session records.
+- Integrate with manifest profiles.
+  - Profiles should be able to select different secret names for different roles/providers, e.g. Orchestrator/Coder/Researcher or web search provider variants.
+  - Profile resolution should validate that referenced secrets exist or produce a clear startup/tool diagnostic.
+  - A profile switch must not require restarting the shell just to change API keys.
+- Provide a small CLI/TUI management surface.
+  - Add/update/list/delete secrets without printing plaintext by default.
+  - Support non-interactive set from stdin for scripts.
+  - Show references and metadata, not secret values.
+  - Consider migration helpers from existing env-var based configuration, but keep migration optional.
+- Update credential consumers.
+  - WebSearch should support encrypted secret refs in addition to env vars.
+  - Provider API keys/tokens and future hosted/search credentials should be able to use the same mechanism.
+  - Existing env-var behavior remains as a fallback/compatibility path.
+- Security and UX constraints.
+  - Fail closed when a referenced secret is missing or cannot be decrypted.
+  - Diagnostics should name the missing reference, not the secret value.
+  - Do not add hidden context injection or history mutation for secret resolution.
+  - Document the threat model and limitations, including OS account access and backup implications.
+
+## Acceptance criteria
+
+- Manifest/profile schema has a typed credential reference that can point either to an env var or encrypted secret-store entry.
+- Encrypted secret-store files are created outside the repository by default and use authenticated encryption with atomic update behavior.
+- A user can add/list/delete a Brave Search API key in the secret store and configure `WebSearch` to use it without exporting an environment variable.
+- Resolved configuration and diagnostics never display plaintext secrets.
+- Missing/decryption-failed secrets produce clear fail-closed errors.
+- Existing env-var based configuration continues to work.
+- Documentation explains how profiles reference secrets and how to manage them.
+- Focused tests cover config parsing/resolution, missing secret diagnostics, no-plaintext serialization/logging paths, and WebSearch secret resolution.
+- `cargo fmt --check`
+- Relevant manifest/provider/tools/pod tests pass.
