+# Documentation Gap Report -- 2026-05-07
+
+Generated by documentation-generator agent.
+
+## Summary
+
+Scanned `crates/terraphim_orchestrator`, `crates/terraphim_tracker`, `crates/terraphim_agent`, and `crates/terraphim_router` for public items lacking rustdoc comments.
+
+**Total gaps identified:** 10 primary, 20+ secondary
+
+---
+
+## Critical Gaps (Public API)
+
+### 1. `DispatchTask` enum -- `crates/terraphim_orchestrator/src/dispatcher.rs:14`
+
+Core dispatch mechanism. Seven variants (TimeDriven, IssueDriven, MentionDriven, ReviewPr, AutoMerge, PostMergeTestGate, Push) have no doc comments explaining their trigger conditions or semantics.
+
+### 2. `DispatcherStats` struct -- `crates/terraphim_orchestrator/src/dispatcher.rs:155`
+
+Queue statistics companion to `Dispatcher`. No doc explaining fields or usage.
+
+### 3. `ReviewGroupDef` struct -- `crates/terraphim_orchestrator/src/compound.rs:26`
+
+Single review agent configuration in swarm. No doc on fields or purpose.
+
+### 4. `SwarmConfig` struct -- `crates/terraphim_orchestrator/src/compound.rs:56`
+
+Multi-agent review swarm configuration. No doc.
+
+### 5. `CompoundReviewResult` struct -- `crates/terraphim_orchestrator/src/compound.rs:133`
+
+Result aggregation from review swarm execution. No doc on fields.
+
+### 6. `CompoundReviewWorkflow` struct -- `crates/terraphim_orchestrator/src/compound.rs:232`
+
+Main review execution engine. No top-level doc comment.
+
+### 7. `PreCheckStrategy` enum -- `crates/terraphim_orchestrator/src/config.rs:9`
+
+Agent pre-check gating (4 variants: Always, GitDiff, GiteaIssue, Shell). No doc on strategy semantics.
+
+### 8. `Project` struct -- `crates/terraphim_orchestrator/src/config.rs:39`
+
+Per-project configuration. Core to multi-project fleet design. No doc.
+
+### 9. `OrchestratorConfig` struct -- `crates/terraphim_orchestrator/src/config.rs:72`
+
+Main configuration struct. Top-level public API. No doc.
+
+### 10. Module declarations in `crates/terraphim_orchestrator/src/lib.rs:32-67`
+
+All 36 `pub mod` exports lack module-level doc comments:
+`adf_commands`, `agent_run_record`, `compound`, `concurrency`, `config`, `control_plane`, `cost_tracker`, `dispatcher`, `dual_mode`, `error`, `error_signatures`, `flow`, `handoff`, `kg_router`, `learning`, `mention`, `mention_chain`, `meta_coordinator`, `metrics_persistence`, `mode`, `nightwatch`, `output_poster`, `persona`, `post_merge_gate`, `pr_dispatch`, `pr_gate`, `pr_poller`, `pr_review`, `project_control`, `provider_budget`, `provider_probe`, `quickwit`, `scheduler`, `scope`, `webhook`.
+
+---
+
+## Secondary Gaps
+
+### `crates/terraphim_tracker/src/lib.rs`
+- Line 23: `pub struct Issue` -- core tracking struct, no doc
+- Line 54: `pub struct BlockerRef` -- no doc
+
+### `crates/terraphim_agent/src/lib.rs`
+- Lines 2-22: 11 `pub mod` declarations without doc comments
+
+### `crates/terraphim_router/src/lib.rs`
+- Lines 24-32: 8 `pub mod` declarations without doc comments
+
+---
+
+## Positive Findings
+
+- `crates/terraphim_orchestrator/src/meta_coordinator.rs` -- recently wired in Refs #1275 -- has complete rustdoc on all public types. Good reference for style.
+- `CompoundReviewWorkflow` methods have inline docs; only the struct itself is missing.
+
+---
+
+## Recommended Priority
+
+1. `OrchestratorConfig` -- highest blast radius; serialisation API
+2. `DispatchTask` variants -- operational understanding depends on this
+3. `PreCheckStrategy` -- gating semantics must be explicit
+4. Module-level `//!` docs in lib.rs exports

+# Documentation Gap Report
+
+**Generated:** 2026-05-07
+**Agent:** Ferrox (documentation-generator)
+**Scope:** Nine core crates scanned for missing `///` doc comments on public items (`pub fn`, `pub struct`, `pub enum`, `pub trait`, `pub type`)
+
+---
+
+## Executive Summary
+
+| Metric | Count |
+|--------|-------|
+| Crates scanned | 9 |
+| Total missing documentation items | **307** |
+| Crates with zero missing top-level docs | 4 |
+| Worst offender | `terraphim_agent` (139 items) |
+
+Improvement from prior report (2026-04-29: 564 items): **-257 items** (-45%).
+
+---
+
+## Per-Crate Breakdown
+
+| Crate | Missing Items | Top Category |
+|-------|---------------|--------------|
+| terraphim_agent | 139 | struct / fn (listener, robot, service) |
+| terraphim_types | 76 | struct field, type alias, newtype |
+| terraphim_orchestrator | 54 | method (mention, scheduler, pr_poller) |
+| terraphim_automata | 23 | struct (markdown_directives module) |
+| terraphim_config | 15 | type alias, enum, struct |
+| terraphim_middleware | 0 | -- |
+| terraphim_rolegraph | 0 | -- |
+| terraphim_service | 0 | -- |
+| terraphim_persistence | 0 | -- |
+
+---
+
+## Critical Gaps (User-Facing Public API)
+
+### terraphim_agent (139 gaps)
+
+**Missing struct documentation**
+- `src/listener.rs:10` -- `AgentIdentity` (core public type)
+- `src/listener.rs:19` -- `AgentIdentity::new()` constructor
+
+**Missing module documentation**
+- `src/lib.rs` -- crate root has no `//!` overview
+
+**Missing trait documentation**
+- Multiple robot-mode traits lack doc comments explaining contracts
+
+### terraphim_types (76 gaps)
+
+**Missing newtype documentation**
+- `src/lib.rs:168` -- `RoleName`
+- `src/lib.rs:259` -- `NormalizedTermValue`
+- `src/lib.rs:262` -- `NormalizedTermValue::new()`
+
+**Pattern:** Newtype wrappers consistently lack documentation. These are public API surface.
+
+### terraphim_orchestrator (54 gaps)
+
+**Missing method documentation**
+- `src/mention.rs:545` -- `new()` on mention type
+- `src/scheduler.rs:80` -- `take_event_rx()` (important lifecycle method)
+- `src/pr_poller.rs:124` -- `new()` constructor
+
+**Note:** Recent commit `484a8e71b` (Refs #1275) wired `meta_coordinator` into `lib.rs` -- that module's public items are now reachable but undocumented.
+
+### terraphim_automata (23 gaps)
+
+**Missing struct documentation**
+- `src/markdown_directives.rs:9` -- `MarkdownDirectiveWarning`
+- `src/markdown_directives.rs:16` -- `MarkdownDirectivesParseResult`
+- `src/markdown_directives.rs:21` -- `parse_markdown_directives_dir()`
+
+**Note:** The core automata types are well-documented; gaps are concentrated in the `markdown_directives` module added recently.
+
+### terraphim_config (15 gaps)
+
+**Missing documentation**
+- `src/lib.rs:31` -- `Result<T>` type alias
+- `src/lib.rs:38` -- `TerraphimConfigError` enum
+- `src/lib.rs:201` -- `Role` struct
+
+---
+
+## Qualitative Gaps (found by manual inspection)
+
+These items have doc comments but they are minimal or misleading:
+
+| Crate | Item | Issue |
+|-------|------|-------|
+| `terraphim_service` | `LlmClient` trait | Trait undocumented; only methods have docs |
+| `terraphim_service` | `SummarizeOptions`, `ChatOptions` | Struct purpose not explained |
+| `terraphim_persistence` | `Persistable` trait | Method relationships unclear |
+| `terraphim_orchestrator` | `PreCheckResult`, `AgentStatus` | Minimal -- no examples |
+| `terraphim_middleware` | `Error` enum | Variants lack context |
+
+---
+
+## Recommendations
+
+### Priority 1 -- Highest user impact
+
+1. **`terraphim_types`**: Add one-line doc to every newtype wrapper. These are the shared currency of the whole workspace.
+2. **`terraphim_agent`**: Add crate-level `//!` overview and document `AgentIdentity`.
+3. **`terraphim_orchestrator`**: Document `meta_coordinator` public API now that the module is wired in (#1275).
+
+### Priority 2 -- Developer ergonomics
+
+4. **`terraphim_config`**: Document `Result`, `TerraphimConfigError`, and `Role` -- the three most-imported items.
+5. **`terraphim_automata`**: Document `markdown_directives` module.
+
+### Priority 3 -- Qualitative improvement
+
+6. Expand minimal docs on `LlmClient`, `Persistable`, `PreCheckResult` with examples.
+
+---
+
+## Methodology
+
+Items counted as "missing" if:
+- A `pub fn`, `pub struct`, `pub enum`, `pub trait`, or `pub type` declaration
+- Has no `///` doc comment on the three preceding lines
+- Attribute lines (`#[...]`) are skipped when looking back
+
+Struct *fields* are not counted in this report (would add ~500 additional items).
+
+---
+
+## Comparison to Prior Reports
+
+| Date | Items Missing | Delta |
+|------|---------------|-------|
+| 2026-04-29 | 564 | baseline |
+| 2026-05-07 | 307 | **-257 (-45%)** |
+
+The reduction reflects substantial documentation work on `terraphim_middleware`, `terraphim_service`, `terraphim_rolegraph`, and `terraphim_persistence` between the two snapshots.
