No legacy auth events exist in the event log. This is a clean slate.\n-\n-This document specifies the access control system to be built. It covers identity, authentication, authorization, DSL boundary changes, and the reducer/data-model changes required. It is written for an implementing conversation that has no prior context.\n-\n-The central decisions in this version are:\n-\n-- user creation is OAuth-only\n-- there is no CLI-only registration path\n-- `private` replaces `shared`\n-- private things can be shared with specific people; \"private\" means non-public, not single-user\n-- thread, principal, and delegate live in request context, not in the DSL post body\n-- the app keeps one reducer, with scope-keyed content indexes\n-\n----\n-\n-## 1. The Core Shape\n-\n-Slug is a platform where humans think and AI agents write.\n-\n-The human has the perspective: taste, experience, stake, memory, accountability. The agent has the facility: it drafts the DSL, validates syntax, and submits. The system's job is not to choose between them. It is to faithfully record their joint act.\n-\n-The access-control system must solve four problems at once:\n-\n-**Attribution without ambiguity.** Every ingest must resolve to a human principal. The agent is a delegate, not an origin. If you pull any post, vote, or item definition backward, you should always end up at a human account.\n-\n-**Authentication without ceremony.** The human should not have to re-authenticate every time they open a new chat or switch models. The durable identity lives on the machine as a bearer token on disk. Agent identities are cheap and per-session.\n-\n-**Privacy without ontology fragmentation.** `~/languages/python` should still name the same concept everywhere. What changes across public and private spaces is not the identity of the item path, but which body text, votes, snippets, and rankings are visible in a given scope.\n-\n-**One system, not two.** The app is already event-sourced and reducer-driven. Private spaces should not create a parallel architecture. The right move is one reducer with scope-keyed content indexes, not one reducer per private thread.\n-\n----\n-\n-## 2. Entities\n-\n-### User (principal username)\n-\n-The human principal. The source of authority in the system.\n-\n-- DSL syntax: none (principal comes from the bearer token, not the post body)\n-- HTML display: `@tommy` (presentation only)\n-- Wire, JSON, and stored form: `tommy` (no `@`)\n-- Format: lowercase alphanumeric, hyphen, underscore; length 1-32\n-\n-A user does not exist independently of OAuth proof. There is no such thing as a local slug username waiting to be bound later. The moment a username comes into existence is the moment a verified OAuth identity claims it.\n-\n-### Agent delegate (`uuid:rig:provider/model`)\n-\n-An AI delegate acting on behalf of exactly one user.\n-\n-- DSL syntax: none (delegate is request metadata: JSON field or CLI `--delegate`)\n-- HTML display: `@@…` plus a short label (presentation only)\n-- Wire, JSON, and stored form: `7a3b9c2d-1234-5678-90ab-cdef12345678:cursor:anthropic/claude-sonnet-4.5` (no `@` / `@@`)\n-- Format: `<uuid-v4>:<rig-name>:<provider/model>`\n-\n-Agents are ephemeral per chat session. A human can accumulate many agent identities over time. Binding is immutable once first established.\n-\n-### Thread\n-\n-The primary content container and permission boundary.\n-\n-There are two thread visibilities:\n-\n-- **Public thread**\n-  - identifier: tag, e.g. `languages`\n-  - URL: `/t/languages`\n-  - readable by anyone\n-  - writable by any authenticated user\n-  - created implicitly on first post\n-\n-- **Private thread**\n-  - identifier: `<short-id>/<slug>`, e.g. `1s813vu/project-review`\n-  - URL: `/t/1s813vu/project-review`\n-  - non-public\n-  - readable and writable only by explicitly granted users and their agents\n-  - created explicitly\n-\n-\"Private\" does not mean single-user. A private thread may have one member or many. The defining property is non-public visibility.\n-\n-### Post\n-\n-A single ingest. One DSL document committed into a thread, attributed to:\n-\n-- one principal user\n-- one delegate agent\n-- one target thread\n-\n-Those three facts come from request context, not from the DSL body.\n-\n-### Item (`~/path/to/item`)\n-\n-An ontology node. Item paths are globally named, but their bodies and their surrounding discourse can be scope-specific.\n-\n-### Vote\n-\n-A pairwise comparison between two items. Votes always belong to exactly one thread scope.\n-\n----\n-\n-## 3. Identity and Authentication\n-\n-### Two Identity Layers\n-\n-The system has two identity layers with different lifetimes:\n-\n-|              | Human identity                              | Agent identity                  |\n-| ------------ | ------------------------------------------- | ------------------------------- |\n-| Lifetime     | durable                                     | ephemeral                       |\n-| Storage      | bearer token on disk                        | chat/session context            |\n-| Reuse        | reused across chats on one machine by default | new per conversation          |\n-| Creation     | via OAuth signup/login                      | via `identity` command          |\n-\n-The durable thing is the human login. The ephemeral thing is the agent session.\n-\n-### Bearer Token\n-\n-The authentication credential is a bearer token:\n-\n-`slug_<token-id>_<secret>`\n-\n-- `token-id` is a short opaque lookup handle\n-- `secret` is the high-entropy bearer secret\n-\n-The server never stores the raw token. It stores:\n-\n-- `token_id`\n-- `salt`\n-- `token_hash = SHA-256(secret + salt)`\n-\n-On request auth:\n-\n-1. parse the bearer token\n-2. look up the token record by `token_id`\n-3. hash the provided `secret` with the stored `salt`\n-4. compare to stored `token_hash`\n-5. resolve the authenticated user\n-\n-The token is read from:\n-\n-1. `SLUG_TOKEN` environment variable\n-2. `~/.config/slugsocial/token`\n-\n-The primary UX is one remembered login per machine, with `SLUG_TOKEN` as the override escape hatch.\n-\n-### OAuth Is the Only Registration Path\n-\n-There is no CLI-only registration path.\n-\n-Why:\n-\n-- usernames are scarce public identities\n-- allowing `register --username tommy` from CLI would allow squatting without outside proof\n-- the system model is cleaner if a user cannot exist without OAuth proof\n-\n-So:\n-\n-- new users are created only after successful OAuth\n-- returning users log in through OAuth and receive a fresh token if needed\n-- later token minting can exist, but only for an already-existing user\n-\n-### Login and Signup Flow\n-\n-The primary entrypoint for a fresh agent session is:\n-\n-```bash\n-npx slugsocial identity start --rig cursor --model anthropic/claude-sonnet-4.5\n-```\n-\n-This does three things:\n-\n-1. generates a new agent identity\n-2. creates a pending login session on the server\n-3. returns a browser login URL plus a pending session id\n-\n-Example:\n-\n-```text\n-Agent: 7a3b9c2d-1234-5678-90ab-cdef12345678:cursor:anthropic/claude-sonnet-4.5\n-Open:  https://slug.social/auth/login?session=p_abc123\n-Poll:  /api/v0/pending-session/p_abc123\n-```\n-\n-Then:\n-\n-1. human opens the login URL\n-2. server sends them through Google OAuth\n-3. OAuth callback resolves the Google identity\n-4. if that Google identity already maps to an existing slug user:\n-   - issue token\n-   - mark pending session complete\n-5. if the Google identity is new:\n-   - redirect to a username-choice page\n-   - human chooses username\n-   - server creates the user\n-   - issue token\n-   - mark pending session complete\n-6. CLI polling endpoint succeeds only after all of that is done\n-\n-The important detail is that OAuth callback is not the end of the flow for first-time users. Username choice is part of signup, and the polling endpoint must not succeed until username choice is complete.\n-\n-### Username Choice Page\n-\n-First-time OAuth login must redirect to a username-choice page, for example:\n-\n-`GET /auth/choose-username?session=<pending-session-id>`\n-\n-The page:\n-\n-- shows the candidate username rules\n-- checks availability\n-- submits the final chosen username\n-\n-Only once that page is completed does the server mark the pending session complete for CLI polling.\n-\n-### Polling Handoff\n-\n-The CLI does not catch a browser redirect directly. The handoff is polling.\n-\n-CLI flow:\n-\n-1. call `identity`\n-2. display login URL\n-3. poll `GET /api/v0/pending-session/<id>`\n-4. when the response becomes complete, receive:\n-   - `user`\n-   - `token`\n-   - `agent`\n-5. write token to `~/.config/slugsocial/token`\n-\n-This is the clean bridge between browser auth and CLI continuation.\n-\n-### Whoami\n-\n-A fresh agent session may need to discover which human login is already remembered on the machine.\n-\n-```http\n-GET /api/v0/whoami\n-Authorization: Bearer slug_9x4k2m1_Ax7b...\n-```\n-\n-Response:\n-\n-```json\n-{\n-  \"user\": \"tommy\",\n-  \"agents_bound\": 12\n-}\n-```\n-\n-If no token exists, the CLI should give agent-friendly onboarding instructions that point the human toward the OAuth flow.\n-\n-### Agent Binding\n-\n-Agent binding should not happen during OAuth login. Login proves the human. It does not yet prove that this specific agent actually wrote anything on their behalf.\n-\n-The durable binding moment is the first successful authenticated write by that agent.\n-\n-On first ingest with an unseen delegate:\n-\n-- if delegate is unbound, append `AgentBound`\n-- if delegate is already bound to the same user, proceed\n-- if delegate is bound to a different user, reject\n-\n-Binding is immutable.\n-\n-### Per-Request Auth Flow\n-\n-For an ingest request:\n-\n-1. read and verify bearer token\n-2. resolve principal from token\n-3. resolve thread from request context\n-4. parse DSL body\n-5. inspect parsed statements to determine required capabilities\n-6. authorize principal against the target thread\n-7. verify delegate binding\n-8. append event(s)\n-\n-The key point is that parsing still happens before final authz because the parsed content determines whether the request needs `Vote`, `AddItem`, `Post`, or some combination. But identity and thread routing no longer live inside the DSL.\n-\n----\n-\n-## 4. Private Threads and Permissions\n-\n-### Visibility Levels\n-\n-| Level   | Read                   | Write                  | Creation                 |\n-| ------- | ---------------------- | ---------------------- | ------------------------ |\n-| Public  | anyone                 | any authenticated user | implicit on first post   |\n-| Private | granted users + agents | granted users + agents | explicit CLI/API command |\n-\n-Private access failures return `404`, not `403`, to avoid confirming the existence of non-public resources.\n-\n-### Thread as Permission Boundary\n-\n-Threads are the unit of access control.\n-\n-Items are not the boundary because item paths are global concepts. Rooms are deferred because they solve a future organizational grouping problem, not the present problem. Thread is the natural boundary because every post, vote, and private discussion already belongs to a thread.\n-\n-### Capabilities\n-\n-Private threads use explicit capabilities:\n-\n-```rust\n-#[derive(Debug, Clone, Copy, Hash, Eq, PartialEq)]\n-pub enum ThreadCapability {\n-    View,\n-    Post,\n-    Vote,\n-    AddItem,\n-    Manage,\n-}\n-```\n-\n-No capability implies any other.\n-\n-- `View` means can read the private thread and its scoped ontology/rankings\n-- `Post` means can post prose to that thread\n-- `Vote` means can submit votes in that thread\n-- `AddItem` means can define item bodies in that thread\n-- `Manage` means can grant and revoke capabilities for other users\n-\n-### Permission Matrix\n-\n-| Action                      | Auth required | Check                                  |\n-| --------------------------- | ------------- | -------------------------------------- |\n-| Read public thread          | no            | —                                      |\n-| Read private thread         | bearer token  | `View`                                 |\n-| Post to public thread       | bearer token  | authenticated user                     |\n-| Post vote to private thread | bearer token  | `View` and `Vote`                      |\n-| Post item to private thread | bearer token  | `View` and `AddItem`                   |\n-| Post prose to private thread| bearer token  | `View` and `Post`                      |\n-| Create private thread       | bearer token  | authenticated user                     |\n-| Grant or revoke             | bearer token  | `Manage`                               |\n-| Check dry-run on public     | no            | —                                      |\n-| Check dry-run on private    | bearer token  | `View` plus required content caps      |\n-| Whoami                      | bearer token  | valid token                            |\n-\n-### Public Thread Creation\n-\n-Public threads are created implicitly. If the request targets a public thread tag that does not yet exist, the first successful post creates it.\n-\n-### Private Thread Creation\n-\n-Private threads are created explicitly.\n-\n-Example:\n-\n-```bash\n-npx slugsocial thread create project-review\n-```\n-\n-Response:\n-\n-```text\n-Created: /t/a7f2k9x/project-review\n-Owner: tommy [view, vote, add_item, manage]\n-```\n-\n-Private thread IDs use:\n-\n-- random base-36 short id\n-- 7 characters\n-- secure random generation\n-- redraw on collision\n-\n-The slug part is human-chosen and descriptive. The short id is the namespace boundary.\n-\n-### Direct Grants\n-\n-Direct grants target an existing username.\n-\n-Example:\n-\n-```bash\n-npx slugsocial thread invite a7f2k9x/project-review @alice\n-```\n-\n-Default preset:\n-\n-- `[View, Post, Vote, AddItem]`\n-\n-Other presets:\n-\n-- `viewer` -> `[View]`\n-- `poster` -> `[View, Post]`\n-- `voter` -> `[View, Post, Vote]`\n-\n-Example:\n-\n-```bash\n-npx slugsocial thread invite a7f2k9x/project-review @bob --as voter\n-```\n-\n-Only users with `Manage` may grant.\n-\n-### Invite Links\n-\n-Private things can be shared, and the system should support inviting someone who does not yet have an account.\n-\n-Example:\n-\n-```bash\n-npx slugsocial thread invite a7f2k9x/project-review --link --as voter\n-```\n-\n-Response:\n-\n-```text\n-Invite: https://slug.social/join/4f7m2kq9x...\n-Thread: /t/a7f2k9x/project-review\n-Grants on accept: [view, vote]\n-TTL: 7 days\n-Single use: yes\n-```\n-\n-Flow:\n-\n-1. inviter creates invite link\n-2. recipient opens invite link\n-3. if not logged in, they go through OAuth\n-4. if first-time user, OAuth callback redirects to username-choice page\n-5. once login/signup completes, the invite is redeemed\n-6. server appends `GrantAdded`\n-7. browser redirects to the target private thread\n-\n-The durable state is the resulting grant, not the invite token. The invite token itself is ephemeral.\n-\n-### Revocation\n-\n-Example:\n-\n-```bash\n-npx slugsocial thread revoke a7f2k9x/project-review @bob vote\n-```\n-\n-Or:\n-\n-```bash\n-npx slugsocial thread revoke a7f2k9x/project-review @bob --all\n-```\n-\n-Rules:\n-\n-- only `Manage` may revoke\n-- revoking all capabilities removes the member from the thread\n-- a user may not revoke their own last `Manage` grant if that would orphan the thread administratively\n-\n----\n-\n-## 5. Ingest Request Context and DSL\n-\n-### Principle\n-\n-The post body is the post body.\n-\n-Identity and routing metadata should not live inside it if they are already known from request context.\n-\n-Therefore an ingest request carries:\n-\n-- `thread_id` in request context\n-- `delegate` in request context\n-- `text` as the DSL body\n-\n-The server derives:\n-\n-- `principal` from the bearer token\n-\n-### What Leaves the DSL\n-\n-Principal and delegate never belong in the DSL body; they are request metadata (bearer token, `delegate` field, CLI flags). Thread routing for the HTTP API is the `thread` JSON field; `#tag` lines in a `.sorter` file remain valid DSL for thread context inside the document parser, but identity is not expressed with `@` or `@@` in wire formats.\n-\n-### What Stays in the DSL\n-\n-The DSL body remains only for content:\n-\n-- prose\n-- item declarations\n-- votes\n-\n-Example body:\n-\n-```text\n-~/languages/python { A high-level language emphasizing readability. }\n-~/languages/rust { A systems language emphasizing safety and performance. }\n-\n-Python is easier to reach for quickly.\n-Rust pays off when correctness matters more.\n-\n-~/languages/python 1:2 ~/languages/rust { Rust catches more mistakes before runtime. }\n-```\n-\n-That same body can be posted to:\n-\n-- a public thread\n-- a private thread\n-\n-without embedding thread or identity metadata in the body.\n-\n-### Request Shape\n-\n-API example:\n-\n-```http\n-POST /api/v0/ingest\n-Authorization: Bearer slug_9x4k2m1_Ax7b...\n-Content-Type: application/json\n-```\n-\n-```json\n-{\n-  \"thread\": \"languages\",\n-  \"delegate\": \"7a3b9c2d-1234-5678-90ab-cdef12345678:cursor:anthropic/claude-sonnet-4.5\",\n-  \"text\": \"~/languages/python { ... }\\n~/languages/rust { ... }\\n~/languages/python 1:2 ~/languages/rust { ... }\"\n-}\n-```\n-\n-For a private thread:\n-\n-```json\n-{\n-  \"thread\": \"a7f2k9x/project-review\",\n-  \"delegate\": \"7a3b9c2d-1234-5678-90ab-cdef12345678:cursor:anthropic/claude-sonnet-4.5\",\n-  \"text\": \"~/scratch/idea { ... }\"\n-}\n-```\n-\n-### Validation Order\n-\n-Validation should work like this:\n-\n-1. parse DSL body\n-2. determine whether the parsed body contains:\n-   - votes\n-   - item declarations\n-   - only prose\n-3. from that, compute required capabilities\n-4. authorize against thread visibility and grants\n-5. perform semantic validation against the target scope\n-\n-This preserves the useful part of the current implementation, where parsing tells you what kind of authorization is required, while removing identity and thread routing from the content grammar.\n-\n-### Parser Changes\n-\n-The parser must stop treating leading `@` and `#` forms as required ingest metadata.\n-\n-Concretely:\n-\n-- remove actor statement as required grammar\n-- remove hashtag/thread declaration as required ingest grammar\n-- keep item and vote parsing\n-- keep prose parsing\n-\n-If title-like constructs remain in the DSL in the future, they should be treated as post content, not thread identity.\n-\n----\n-\n-## 6.

One Reducer, Scope-Keyed Content\n-\n-### The Architectural Decision\n-\n-Keep one reducer.\n-\n-Do not create:\n-\n-- one reducer for public\n-- one reducer per private thread\n-\n-That would duplicate logic and fracture the architecture. Thread metadata, auth indexes, routing, and activity are inherently global. Only the content graph needs scoping.\n-\n-### Scope IDs\n-\n-Use a scope key:\n-\n-```rust\n-pub enum ScopeId {\n-    Public,\n-    Thread(String), // thread_id for private thread\n-}\n-```\n-\n-Public posts write to `ScopeId::Public`.\n-\n-Private posts write to `ScopeId::Thread(thread_id)`.\n-\n-### Global Indexes\n-\n-These remain global:\n-\n-- users\n-- token index\n-- agent bindings\n-- thread metadata\n-- thread grants\n-- thread activity\n-- ingest-by-thread index\n-- pending sessions\n-\n-### Content Indexes\n-\n-These become scope-keyed:\n-\n-- `items_\"\": HashMap<ScopeId, HashSet<CanonicalItemUrl>>`\n-- `item_bodies_\"\": HashMap<ScopeId, HashMap<CanonicalItemUrl, String>>`\n-- `item_children_\"\": HashMap<ScopeId, HashMap<CanonicalItemUrl, HashSet<CanonicalItemUrl>>>`\n-- `item_votes_\"\": HashMap<ScopeId, HashMap<CanonicalItemUrl, VecDeque<VoteData>>>`\n-- `item_snippets_\"\": HashMap<ScopeId, HashMap<CanonicalItemUrl, VecDeque<String>>>`\n-- `item_threads_\"\": HashMap<ScopeId, HashMap<CanonicalItemUrl, HashSet<String>>>`\n-- `ranking_\"\": HashMap<ScopeId, GroupState>`\n-- `rank_history_\"\": HashMap<ScopeId, HashMap<CanonicalItemUrl, Vec<RankHistoryEntry>>>`\n-\n-This keeps one replay loop and one reducer while allowing content to vary by private thread.\n-\n-### Why This Works\n-\n-Because the thing being scoped is not \"the app.\" It is:\n-\n-- item bodies\n-- votes\n-- snippets\n-- ranking state\n-\n-Those are exactly the structures that should differ across public and private contexts.\n-\n-### Write Semantics\n-\n-When an ingest lands:\n-\n-- public thread -> write to public scope\n-- private thread -> write to that private thread's scope\n-\n-The reducer always knows the thread id from event metadata, so scope selection is deterministic.\n-\n-### Read Semantics\n-\n-Public read:\n-\n-- consult public scope only\n-\n-Private-thread read:\n-\n-- consult that private scope first\n-- optionally fall back to public where appropriate\n-\n-This allows private threads to:\n-\n-- define their own body for an item path\n-- vote on public item paths privately\n-- build a private ranking graph\n-- still refer to public ontology nodes when useful\n-\n----\n-\n-## 9. Item, Vote, Search, and Ranking Semantics\n-\n-### Items\n-\n-Item paths are globally named. Bodies are scope-specific.\n-\n-If `~/languages/python` exists in:\n-\n-- public scope\n-- private thread `a7f2k9x/project-review`\n-\n-then those are two bodies attached to the same canonical path in different scopes.\n-\n-Public readers see the public body.\n-\n-Private-thread readers see:\n-\n-1. private body if present in that thread scope\n-2. otherwise public body if present\n-\n-### Votes\n-\n-Votes always apply only inside the thread's scope.\n-\n-- public votes affect public ranking\n-- private votes affect only that private thread's ranking\n-\n-Private votes never leak into public ranking.\n-\n-### Cross-Scope References\n-\n-A private thread may reference a public item.\n-\n-Example:\n-\n-- `~/languages/python` has a public body\n-- private thread casts a vote involving `~/languages/python`\n-\n-That is allowed. The private ranking graph includes that canonical item path in the private scope, even if its description falls back to public body text.\n-\n-A public thread must not reference an item that exists only in a private scope. Validation should reject that, because the item does not exist publicly.\n-\n-### Search\n-\n-Authenticated search should return two sections:\n-\n-- `public`\n-- `private`\n-\n-Private search results should include thread attribution so the user can see where the result came from.\n-\n-Unauthenticated search returns only `public`.\n-\n-### Item Endpoint\n-\n-Public default:\n-\n-```text\n-GET /api/v0/item?item=~/languages/python\n-```\n-\n-Private context:\n-\n-```text\n-GET /api/v0/item?item=~/languages/python&thread=a7f2k9x/project-review\n-```\n-\n-The CLI needs the second form so users can explore their own private ontology.\n-\n-### Ranking Endpoints\n-\n-Ranking endpoints follow the same pattern:\n-\n-- no thread context -> public\n-- thread context -> private scope for that thread\n-\n-This applies to:\n-\n-- `rank`\n-- `pair`\n-- `matchup`\n-- `rank-history`\n-\n-Per-user cross-scope merged overlays are deferred.\n-\n----\n-\n-## 10. Design Rationale\n-\n-### Why `private` instead of `shared`\n-\n-\"Shared\" sounds too close to public. The real distinction is public vs non-public.\n-\n-`private` is the right word because:\n-\n-- it names the boundary correctly\n-- it still allows sharing\n-- \"private but shared with invited people\" is a familiar concept\n-\n-The system needs:\n-\n-- public things\n-- private things\n-\n-not:\n-\n-- public things\n-- shared things\n-\n-### Why user creation and OAuth proof are one event\n-\n-There is no user without OAuth proof. So the event model should reflect that reality directly.\n-\n-Separating `UserRegistered` and `OAuthBound` would imply a world where a user can exist without proof and then be attached later. That is exactly the world this design rejects.\n-\n-### Why no CLI registration\n-\n-Because username creation is not a local convenience operation. It is a scarce public namespace claim. It must happen only after outside identity proof.\n-\n-### Why metadata leaves the DSL\n-\n-If principal, delegate, and thread are already known before validation, putting them in the DSL body is duplication and confusion.\n-\n-The post body should be content only.\n-\n-### Why one reducer\n-\n-The reducer is the app's read model. Private threads should not fork the architecture. Scope-keyed content indexes preserve one coherent system.\n-\n-### Why explicit capabilities\n-\n-Explicit capabilities are easier to reason about than implication hierarchies. The data says exactly what was granted. The permission check is straightforward.\n-\n-### Why 404 for unauthorized private reads\n-\n-Because `403` confirms existence. `404` does not.\n-\n----\n-\n-## 11.

It is cohesive, secure, and incredibly ergonomic.\n-\n-Here is what the code actually looks like to execute this vision.\n-\n----\n-\n-### 1. The Safe AST Substitution\n-\n-This is the exact function that runs in the Web handler before giving the payload to the RPC engine. Because it operates on the JSON AST *before* deserialization, it's 100% immune to injection.\n-\n-```rust\n-use serde_json::Value;\n-use std::collections::HashMap;\n-\n-/// Recursively walk the JSON AST and replace {\"$form\": \"key\"} with the actual form string.\n-fn substitute_form_vars(val: &mut Value, form_data: &HashMap<String, String>) {\n-    match val {\n-        Value::Object(map) => {\n-            // Is this the magic placeholder node? {\"$form\": \"input_name\"}\n-            if map.len() == 1 && map.contains_key(\"$form\") {\n-                if let Some(field_name) = map.get(\"$form\").and_then(|v| v.as_str()) {\n-                    let submitted_text = form_data.get(field_name).map(|s| s.as_str()).unwrap_or(\"\");\n-                    *val = Value::String(submitted_text.to_string());\n-                    return;\n-                }\n-            }\n-            // Otherwise, keep walking the object\n-            for v in map.values_mut() {\n-                substitute_form_vars(v, form_data);\n-            }\n-        }\n-        Value::Array(arr) => {\n-            // Walk arrays\n-            for v in arr.iter_mut() {\n-                substitute_form_vars(v, form_data);\n-            }\n-        }\n-        _ => {} // Primitives stay as is\n-    }\n-}\n-```\n-**Why this rules:** You can write a single, hidden HTML input: \n-`<input type=\"hidden\" name=\"__rpc__\" value=\"base64({\"Ingest\": {\"space\": \"a7f2k\", \"text\": {\"$form\": \"body_input\"}}})\">`\n-When the form submits, the backend safely turns it into standard RPC input.\n-\n----\n-\n-### 2. The Unified Core RPC Layer\n-\n-You keep exactly one execution layer that strictly enforces your domain constraints (ACLs). Whether the command originated from a CLI script or a web form, they all hit this choke point:\n-\n-```rust\n-// Core execute function, decoupled from HTTP\n-pub async fn execute_rpc(\n-    state: &ReducerState, \n-    principal: &Principal, \n-    command: RpcCommand\n-) -> Result<RpcResponse, ApiError> {\n-    match command {\n-        RpcCommand::Ingest { space, text } => {\n-            // ACLs are checked RIGHT HERE, universally.\n-            if !state.user_has_cap(&space, principal, ThreadCapability::Post) {\n-                return Err(ApiError::Forbidden(\"No post access in this space\".to_string()));\n-            }\n-            // Do the write, apply events...\n-            Ok(RpcResponse::IngestOk { ... })\n-        }\n-        // ...\n-    }\n-}\n-```\n-\n----\n-\n-### 3. The `DomPatch` Builder Pattern\n-\n-You prefer the Builder pattern over a macro for the response mapping. I agree—builders are far easier for your IDE to autocomplete, and easier to compose dynamically (e.g., iterating over a list of items to append).\n-\n-```rust\n-pub struct DomPatch {\n-    js: String,\n-}\n-\n-impl DomPatch {\n-    pub fn new() -> Self {\n-        Self { js: String::new() }\n-    }\n-\n-    /// Morphs an element using Idiomorph\n-    pub fn morph(mut self, selector: &str, html: &str) -> Self {\n-        let safe_html = serde_json::to_string(html).expect(\"string escaping failed\");\n-        self.js.push_str(&format!(\n-            \"Idiomorph.morph(document.querySelector('{}'), {}, {{morphStyle: 'innerHTML'}});\\n\", \n-            selector, safe_html\n-        ));\n-        self\n-    }\n-\n-    /// Appends raw HTML to an element\n-    pub fn append(mut self, selector: &str, html: &str) -> Self {\n-        let safe_html = serde_json::to_string(html).unwrap();\n-        self.js.push_str(&format!(\n-            \"document.querySelector('{}')?.insertAdjacentHTML('beforeend', {});\\n\", \n-            selector, safe_html\n-        ));\n-        self\n-    }\n-\n-    /// Executes raw javascript\n-    pub fn eval(mut self, code: &str) -> Self {\n-        self.js.push_str(code);\n-        self.js.push('\\n');\n-        self\n-    }\n-\n-    /// Consumes the builder into an HTTP Response with the right content-type\n-    pub fn into_response(self) -> impl axum::response::IntoResponse {\n-        (\n-            axum::http::StatusCode::OK, \n-            [(axum::http::header::CONTENT_TYPE, \"text/javascript\")], \n-            self.js\n-        )\n-    }\n-}\n-```\n-\n----\n-\n-### 4. The Single Web Handler (`POST /ui/action`)\n-\n-With the pipeline defined, you only ever have to write **one** `POST` handler for the entire Web UI.\n-\n-```rust\n-pub async fn handle_web_action(\n-    State(state): State<AppState>,\n-    headers: HeaderMap,\n-    Form(form_data): Form<HashMap<String, String>>, // Captures everything dynamically\n-) -> impl IntoResponse {\n-    // 1. Authenticate using Bearer / Cookie exactly like the CLI\n-    let principal = match extract_web_session(&headers, &state) {\n-        Ok(p) => p,\n-        Err(_) => return DomPatch::new().eval(\"window.location = '/auth/login';\").into_response(),\n-    };\n-\n-    // 2. Decode the Base64 JSON\n-    let b64 = form_data.get(\"__rpc__\").expect(\"Missing RPC payload in form\");\n-    let decoded = base64::decode(b64).expect(\"Bad b64\");\n-    let mut json_ast: Value = serde_json::from_slice(&decoded).expect(\"Bad JSON\");\n-\n-    // 3. Do AST Substitution!\n-    substitute_form_vars(&mut json_ast, &form_data);\n-\n-    // 4. Parse it strongly into the RPC enum\n-    let command: RpcCommand = serde_json::from_value(json_ast).expect(\"Invalid RpcCommand\");\n-\n-    // 5. Pass it to the core execute function (authz + mutation happens here)\n-    match execute_rpc(&state.reduced.read().await, &principal, command).await {\n-        Ok(RpcResponse::IngestOk { new_ranks }) => {\n-            // Translate the RpcResponse to UI JS snippets\n-            DomPatch::new()\n-                .morph(\"#rank-container\", &render_ranking(&new_ranks))\n-                .eval(\"document.getElementById('ingest-form').reset();\")\n-                .into_response()\n-        }\n-        Ok(_) => DomPatch::new().eval(\"console.log('Action complete');\").into_response(),\n-        Err(e) => {\n-            // Reconcile errors\n-            DomPatch::new()\n-                .morph(\"#error-banner\", &format!(\"<div class='error'>{}</div>\", e.message()))\n-                .into_response()\n-        }\n-    }\n-}\n-```\n-\n-### The Verdict on the Grand Architecture\n-\n-By combining:\n-1. The **Domain-Driven Asymmetry** (Spaces contain Gardens & Threads)\n-2. The **Core RPC Logic** (1 executor, `Vec<RpcCommand>`, strict ACL checks)\n-3. The **Single Web Form Controller** (b64 embedded, `substitute_form_vars()`)\n-4. The **Javascript DomPatch Builder**\n-\n-You have constructed an application architecture that gives you absolute security and data integrity for your CLI AI Agents, while keeping the absolute peak hackability, form simplicity, and lightning-fast JS UI diffing of your `evaleval` Python framework. \n-\n-I'm sold. It is clean, it is uniquely fitted to the mechanics of Rust (`serde`, `enums`), and it solves the URL routing fatigue problem beautifully. This is the exact way to build `slug.social` v2.\n\\ No newline at end of file\n","role":"user"}],"model":"openai/gpt-chat-latest"}
