# Phase 14: Documentation -- Verification

**Goal-backward check:** Do the created docs actually describe the real code?

## Gate Result: FAIL

The documentation is **comprehensive and accurate** in content, but fails on one requirement: a cross-link to a non-existent source file. This is documented below as a concrete gap.

---

## Files Created -- Existence Check

| # | File | Status | Notes |
|---|------|--------|-------|
| 1 | `docs/README.md` | EXISTS | Project overview, tech stack table, how-to-contribute, build/run, test patterns |
| 2 | `docs/architecture/overview.md` | EXISTS | ASCII architecture diagram, data flow (read/write/graph/tag/bulk), component map, architectural decisions |
| 3 | `docs/architecture/graph-subsystem.md` | EXISTS | Deep-dive: data model (page_links, page_tags, graph_meta), store, extract, rebuild, query, async job, HTTP endpoints, popular-tag cap |
| 4 | `docs/architecture/tag-subsystem.md` | EXISTS | Deep-dive: suggest/stage/review/approve flow, SuggestTags mode, sweep & staging, byte-stable apply, HTTP endpoints, safety guarantees |
| 5 | `docs/api/graph.md` | EXISTS | GraphData, Neighborhood, Backlinks, reindex endpoint contracts |
| 6 | `docs/api/tagsweep.md` | EXISTS | Suggest-tags, apply-tags, sweep, suggestions list, approve endpoint contracts |
| 7 | `README.md` | UPDATED | v1.0 Features section added (graph, backlinks, LLM tagging, bulk sweep, admin rebuild) |

Result: All 7 files exist and are non-empty. PASS.

---

## Architecture Diagram (docs/architecture/overview.md)

The ASCII diagram (lines 7-57) accurately depicts the layered architecture:

- Browser (React SPA) with Graph UI (D3), Page View/Editor, Settings/Admin, File Tree
- Go Backend (chi) with Graph/Pages/Admin/Auth handler layers
- Graph Store (SQLite), Pages Service, Search Index (Bleve), Auth Service
- Repo Layer (internal/repo) as filesystem chokepoint
- Filesystem with content/ and .okf.git/
- app.db SQLite tables listed

Data flow sections (Read Path, Write Path, Graph Read Path, Tag Suggestion Flow, Bulk Sweep Flow) accurately describe the actual code paths. PASS.

---

## Source Cross-Links -- Spot Check

Every source file referenced in the docs was verified to exist:

### docs/architecture/overview.md
- Component map references `internal/repo`, `internal/pages`, `internal/graph`, `internal/tagsweep`, `internal/agent`, `internal/search`, `internal/auth`, `internal/server`, `internal/okf`, `internal/jobs`, `internal/store` -- all verified. PASS.

### docs/architecture/graph-subsystem.md
- `internal/graph/store.go` -- verified, line 1: `// Package graph maintains the DERIVED link/tag adjacency cache`
- `internal/graph/extract.go` -- verified, `func outboundLinks` at line 26
- `internal/graph/rebuild.go` -- verified, `func RebuildGraph` at line 22
- `internal/graph/query.go` -- verified, `popularTagShare = 0.25`, `popularTagMinPages = 8`
- `internal/graph/graphjob.go` -- verified, `const KindGraph = "graph"`, `graphPayload` struct
- All substructure descriptions match: DriftCheck, outboundLinks extraction, RebuildGraph two-pass, query layer pattern, popular-tag cap. PASS.

### docs/architecture/tag-subsystem.md
- `internal/agent/suggesttags.go` -- verified, `MaxSuggestedTags = 5`, `maxTagLen = 40`, `suggestTagsMaxTokens = 256`, `suggestTagsTemperature = 0.2`
- `internal/agent/prompts.go` -- verified, prompt-injection discipline, `buildSuggestTagsMessages`
- `internal/tagsweep/store.go` -- verified, `tag_suggestions` table, `trashPrefix`
- `internal/tagsweep/job.go` -- verified, `KindTagSuggest = "tag_suggest"`, `suggestPayload`
- `internal/pages/batch.go` -- verified, `ApplyTagsBatch`, `TagApplyApplied/Stale/NotFound` consts
- `internal/okf/repair.go` -- verified, `func SetTags(d *Doc, tags []string)` at line 160
- All flow descriptions (suggest/stage/review/approve, safety guarantees T-12-06, T-12-07) match actual code. PASS.

### docs/api/graph.md
- `internal/server/handlers_graph.go` -- verified by search
- `internal/server/router.go` lines 181-183, 290 -- verified: authed.Get("/graph"), authed.Get("/graph/local"), authed.Get("/graph/backlinks"), admin.Post("/admin/graph/reindex")
- `internal/graph/query.go` -- GraphData, Neighborhood, Backlinks -- verified
- `internal/graph/rebuild.go` -- RebuildGraph -- verified
- `internal/server/handlers_search.go` -- handleGraphReindex -- verified at line 92. PASS.

### docs/api/tagsweep.md
- `internal/server/handlers_tagsweep.go` -- verified by search
- `internal/server/router.go` lines 209, 233, 297-298, 306 -- verified: authed.Post("/agent/suggest-tags"), editor.Post("/agent/apply-tags"), admin.Post("/admin/tags/sweep"), admin.Get("/admin/tags/suggestions"), admin.Post("/admin/tags/approve")
- `internal/agent/suggesttags.go` -- SuggestTags -- verified
- `internal/tagsweep/store.go` -- Targets, ListPending -- verified
- `internal/server/handlers_tagsweep.go` -- handleStartTagSweep, handleApproveTagSuggestions -- verified
- `internal/pages/batch.go` -- ApplyTagsBatch -- verified

**GAP FOUND:** `docs/api/tagsweep.md` line 78 references `internal/agent/apply.go` which does NOT exist. The correct source for `POST /api/v1/agent/apply-tags` is `internal/server/handlers_agent.go` where `handleApplyTags` lives at line 710. The `okf/repair.go` reference is correct (SetTags is there).

## API Docs vs Real Handlers -- Endpoint Contract Spot Check

| API Doc Endpoint | Method | Route | Handler Verified | Notes |
|-----------------|--------|-------|------------------|-------|
| `/api/v1/graph` | GET | `authed.Get("/graph", ...)` | `handleGraph` in handlers_graph.go | PASS |
| `/api/v1/graph/local` | GET | `authed.Get("/graph/local", ...)` | `handleGraphLocal` in handlers_graph.go | PASS |
| `/api/v1/graph/backlinks` | GET | `authed.Get("/graph/backlinks", ...)` | `handleGraphBacklinks` in handlers_graph.go | PASS |
| `/api/v1/admin/graph/reindex` | POST | `admin.Post("/admin/graph/reindex", ...)` | `handleGraphReindex` in handlers_search.go:92 | PASS |
| `/api/v1/agent/suggest-tags` | POST | `authed.Post("/agent/suggest-tags", ...)` | `handleSuggestTags` in handlers_agent.go:650 | PASS |
| `/api/v1/agent/apply-tags` | POST | `editor.Post("/agent/apply-tags", ...)` | `handleApplyTags` in handlers_agent.go:710 | PASS |
| `/api/v1/admin/tags/sweep` | POST | `admin.Post("/admin/tags/sweep", ...)` | `handleStartTagSweep` in handlers_tagsweep.go:49 | PASS |
| `/api/v1/admin/tags/suggestions` | GET | `admin.Get("/admin/tags/suggestions", ...)` | `handleListTagSuggestions` in handlers_tagsweep.go:268 | PASS |
| `/api/v1/admin/tags/approve` | POST | `admin.Post("/admin/tags/approve", ...)` | `handleApproveTagSuggestions` in handlers_tagsweep.go:137 | PASS |

All route registrations, auth requirements, and handler names match the actual code. PASS (with the source cross-link note for apply-tags).

## Summary

The documentation is well-written, comprehensive, and accurately describes the real codebase. Every endpoint listed in the API docs matches the actual route registrations and handler implementations. Every source file referenced in cross-links exists -- with one exception.

### Gap

**Cross-link to non-existent file in `docs/api/tagsweep.md:78`.** The `POST /api/v1/agent/apply-tags` endpoint source is listed as `internal/agent/apply.go`, but that file does not exist. The actual handler is `internal/server/handlers_agent.go` function `handleApplyTags` at line 710. Fix: change the link from `internal/agent/apply.go` to `internal/server/handlers_agent.go`.

### Verdict

The documentation content accurately describes the real codebase, meeting the goal-backward standard. This is a single minor documentation cross-link error.

**gate_result: fail** -- the DOC-01 requirement that "All docs cross-link to relevant code files" is not fully satisfied.

**Recommended fix:** Update `docs/api/tagsweep.md` line 78 to reference `internal/server/handlers_agent.go` instead of the non-existent `internal/agent/apply.go`.
