+# lark-cli Plugin SDK
+
+`extension/platform` is the **in-process plugin SDK** for lark-cli.
+Plugins compile into a **fork** of the lark-cli binary via a blank
+import; there is no `.so` loading, no RPC, no subprocess isolation.
+A plugin shares the binary's address space and lifecycle.
+
+## 5-minute hello world
+
+```go
+// myplugin/audit.go
+package myplugin
+
+import (
+    "context"
+    "log"
+
+    "github.com/larksuite/cli/extension/platform"
+)
+
+func init() {
+    platform.Register(
+        platform.NewPlugin("audit", "0.1.0").
+            Observer(platform.After, "log-cmd", platform.All(),
+                func(ctx context.Context, inv platform.Invocation) {
+                    log.Printf("cmd=%s err=%v", inv.Cmd().Path(), inv.Err())
+                }).
+            FailOpen().
+            MustBuild())
+}
+```
+
+Wire into a fork:
+
+```go
+// cmd/larkx/main.go in your fork
+package main
+
+import (
+    _ "github.com/me/myplugin"  // blank import → init() runs
+
+    "github.com/larksuite/cli/cmd"
+    "os"
+)
+
+func main() { os.Exit(cmd.Execute()) }
+```
+
+```sh
+go build -o larkx ./cmd/larkx && ./larkx config plugins show
+```
+
+You should see `audit` in the plugin list.

+
+A `command_denied` decision (from `Restrict` or strict-mode) bypasses
+the `Wrap` chain entirely — observers still fire so audit plugins see
+the rejected dispatch.
+
+## Safety contract (read this)
+
+- A plugin calling `Restrict()` MUST declare `FailClosed`. The Builder
+  flips it automatically; the lower-level `Plugin` interface rejects
+  the mismatch with `restricts_mismatch`.
+- Only ONE plugin per binary can call `Restrict()`. Multi-plugin
+  Restrict is a deliberate `plugin_conflict` error (single-rule
+  ecosystem assumption). YAML policy at `~/.lark-cli/policy.yml` is
+  shadowed by any plugin Restrict.
+- The `Wrap` factory runs **once per command dispatch**, not at
+  install time. Long-lived state (clients, caches, metrics counters)
+  must live on the Plugin struct or in package-level variables.
+- Plugins cannot suppress a `command_denied`: the framework
+  physically isolates denied commands from the Wrap chain (Observers
+  still fire).
+- Commands missing a `risk_level` annotation are denied by default
+  when a Rule is active. Set `Rule.AllowUnannotated = true` (or
+  `allow_unannotated: true` in yaml) to opt out during gradual
+  adoption.
+- Risk annotation typos (e.g. `"wrtie"`) are always denied with
+  `risk_invalid` plus a "did you mean" suggestion. `AllowUnannotated`
+  does NOT bypass this — typo is a code bug, not a missing
+  annotation.
+
+## reason_code reference
+
+Every install / dispatch failure emits a `command_denied` or
+`plugin_install` envelope carrying a `detail.reason_code` from the
+closed enum below. Use the code (not the human-readable message) when
+matching errors in agents, CI scripts, or downstream tools — the
+messages are localised and may change between releases.
+
+### Plugin install (`error.type = plugin_install`)
+
+| reason_code                 | When it fires                                                                  | Honours FailurePolicy? |
+| --------------------------- | ------------------------------------------------------------------------------ | ---------------------- |
+| `invalid_plugin_name`       | `Plugin.Name()` doesn't match `^[a-z0-9][a-z0-9-]*$`                           | No — always aborts     |
+| `plugin_name_panic`         | `Plugin.Name()` panicked                                                       | No — always aborts     |
+| `duplicate_plugin_name`     | Two plugins return the same `Name()`                                           | No — always aborts     |
+| `capabilities_panic`        | `Plugin.Capabilities()` panicked                                               | Yes                    |
+| `invalid_capability`        | `Capabilities` malformed: bad `RequiredCLIVersion`, unknown `FailurePolicy`    | No — always aborts     |
+| `capability_unmet`          | Current CLI version doesn't satisfy `RequiredCLIVersion`                       | Yes                    |
+| `restricts_mismatch`        | `Restricts=true` without `FailClosed`, or `Restricts` flag inconsistent w/ Install | No — always aborts |
+| `invalid_hook_name`         | Hook name contains `.` or doesn't match the plugin namespace                   | Yes                    |
+| `duplicate_hook_name`       | Same hook name registered twice within a plugin                                | Yes                    |
+| `invalid_hook_registration` | Hook factory returns nil / Wrap chain re-entry / etc.                          | Yes                    |
+| `invalid_rule`              | Rule fails ValidateRule (malformed glob, bad MaxRisk, unknown Identity)        | Yes                    |
+| `double_restrict`           | Plugin called `r.Restrict()` more than once in one Install                     | Yes                    |
+| `multiple_restrict_plugins` | Two or more plugins each contributed Restrict                                  | Yes                    |
+| `install_failed`            | `Plugin.Install` returned a non-nil error                                      | Yes                    |
+| `install_panic`             | `Plugin.Install` panicked                                                      | Yes                    |
+
+"No — always aborts" entries are treated as **untrusted-config errors**:
+the host can't honour the plugin's declared `FailurePolicy` because the
+declaration itself is suspect (e.g. an `invalid_capability` plugin
+might also be lying about being `FailOpen`).
+
+### Command dispatch (`error.type = command_denied`)
+
+| reason_code             | Meaning                                                                                                          |
+| ----------------------- | ---------------------------------------------------------------------------------------------------------------- |
+| `risk_not_annotated`    | Command has no `risk_level` annotation, and the active Rule does not set `allow_unannotated: true`               |
+| `risk_invalid`          | Command's `risk_level` is a typo / not in the `read | write | high-risk-write` taxonomy (always fail-closed)     |
+| `command_denylisted`    | Command path matched the active Rule's `deny` glob                                                               |
+| `domain_not_allowed`    | Active Rule has a non-empty `allow` list and the command path did not match any glob                             |
+| `write_not_allowed`     | Command risk is `write` / `high-risk-write` and exceeds Rule `max_risk`                                          |
+| `risk_too_high`         | Command risk exceeds Rule `max_risk` but is not a write (reserved for future risk levels)                        |
+| `identity_mismatch`     | Command's `supportedIdentities` does not intersect Rule `identities`                                             |
+| `aggregate_all_denied`  | Aggregate stub installed on a parent group because every live child was denied                                   |
+
+The `detail.layer` field distinguishes who rejected the call:
+`policy` (this SDK's user-layer engine) vs. `strict_mode`
+(`cmd/prune.go`'s credential-hardening pass). Agents that want to
+dispatch on "any denial" should match `error.type == "command_denied"`
+and ignore the layer; agents that only care about user-policy denials
+should additionally check `detail.layer == "policy"`.
+
+## Where to go next
+
+- [Runnable example: audit observer](./examples/audit-observer/)
+- [Runnable example: read-only policy](./examples/readonly-policy/)
+- Builder API: see [`builder.go`](./builder.go) for the full DSL
+  (`NewPlugin`, `Observer`, `Wrap`, `Restrict`, `FailOpen`/`FailClosed`,
+  `MustBuild`).
+- Inventory diagnostic: run `lark-cli config plugins show` after
+  installing your plugin to see hooks/rules attributed to your plugin
+  name.

+// Package platform is the single public extension contract for lark-cli.
+//
+// External integrators (plugin authors, embedding platforms) only import this
+// package; everything else under internal/ is off-limits.
+//
+// Plugin lifecycle:
+//
+//   - Plugin         - the interface every plugin implements (Name / Version / Capabilities / Install)
+//   - Registrar      - what Install receives; the four registration verbs (Observe / Wrap / On / Restrict)
+//   - Capabilities   - declared up front: FailurePolicy (FailOpen | FailClosed) and Restricts
+//   - Register       - process-wide entry point; plugins call this from init()
+//
+// Hook surface (what Install hangs off Registrar):
+//
+//   - Observer       - side-effect-only callback, panic-safe, runs Before / After RunE
+//   - Wrapper        - middleware that can short-circuit via AbortError
+//   - LifecycleHandler - reacts to Startup / Shutdown / etc. (LifecycleEvent + When)
+//   - Selector       - chooses which commands a hook applies to (ByDomain / ByWrite / ByReadOnly / ByExactRisk / And / Or / Not, etc.)
+//   - Handler        - the inner "run the command" function Wrappers compose around
+//   - Invocation     - per-call context passed to handlers (Cmd view + DeniedByPolicy / DenialLayer / DenialPolicySource)
+//   - AbortError     - structured short-circuit error from a Wrapper; framework namespaces HookName
+//
+// Policy surface (what Restrict contributes, also consumable from yaml policy):
+//
+//   - Rule              - declarative policy rule (Allow / Deny / MaxRisk / Identities / AllowUnannotated)
+//   - CommandView       - read-only command metadata view (Path / Domain / Risk / Identities)
+//   - Risk / Identity   - defined string types with closed taxonomies; ParseRisk / ParseIdentity
+//     convert raw strings (yaml, cobra annotation) into typed values; r.Rank()
+//     gives a comparable rank for the read < write < high-risk-write ordering
+//   - CommandDeniedError - structured error returned to denied callers
+//
+// Stability: every exported symbol here is part of the contract. Internal
+// orchestration (staging, validation, RunE wrapping, denial guard) lives
+// under internal/platform, internal/hook and internal/cmdpolicy and is not
+// importable by third parties.
