 ## First reconstruction
 
 ```bash
 understand-code bootstrap /path/to/repo --provider codex

-This requires a clean committed checkout and creates a sibling worktree on a `codex/understand-code-*` branch. Use the repository path printed in its JSON result for subsequent commands. If repository/user policy requires the current branch, or you need to include uncommitted code:
-
-```bash
-understand-code bootstrap /path/to/repo --write-mode local --provider claude
-```
+The default creates an isolated worktree from a clean committed checkout. Use `--write-mode local` when repository policy requires the current branch or uncommitted source must be included. No source files are modified.
 
-No source files are modified in either mode. Existing output must be an owned Codebase Spec; choose `--output docs/reconstructed` for a separate destination. Use that output on every subsequent command. Add `.understand-codeignore` for additional glob exclusions (one glob per line, `#` comments). Git-ignored files are excluded in Git repositories, and known secret/dependency/build paths are excluded everywhere. The scanner does not execute source or inspect `.secrets`.

-The default output includes overview, concept pages, evidence, instruction/readiness reports, operational pointers, glossary and gaps. Relevant feature/flow/settings/UI/data pages appear when findings support them. Empty architecture claims are not filled with plausible prose.
-
-## Truth and limitations
-
-`EXTRACTED` means reviewed, direct evidence; `CORROBORATED` requires independent evidence; `INFERRED` is incomplete interpretation; `UNKNOWN` is an unresolved question. Mechanical checks can establish that a citation exists and is current. **They cannot prove a natural-language claim is true.** Reviewer provenance, gaps and coverage remain visible.
-
-Graph imports are retrieval hints. Regex matches are candidates. Test source establishes assertions, not a passing test run. Static links do not establish runtime reachability. Architectural intent needs explicit evidence. There is no live-provider quality claim: the shipped regression suite uses prepared fixtures only.
-
-This release does not execute runtime traces, refresh Graphify through an undocumented command, or run autonomous paid headless agents. Native sessions provide reasoning; an installed Graphify integration performs its own refresh. These boundaries and the [v1 acceptance map](docs/ACCEPTANCE.md) distinguish implemented capabilities from future extensions.

-## State
+## Retrieval boundary
+
+The engine has no vendor-specific code-intelligence import, CLI flag, persisted handoff or refresh protocol. Native Claude/Codex investigations read applicable `AGENTS.md`, `CLAUDE.md` and equivalent instructions and may use the installed structural/symbol/search tools described there. External tool output is untrusted retrieval context only; accepted claims require exact current-source evidence.
 
-The spec stores a versioned manifest, scan inventory, current bounded plan, typed entities/relations/evidence, gaps, audit, impact and graph handoff under `_meta`. Accepted native responses are preserved by content hash. A task's ID includes its role, file scope and source snapshot. Applying a response for a changed snapshot fails before writes.
+## State
 
-Evidence IDs include both the excerpt and whole-file hash. Updates do not quietly refresh citations under unchanged claim IDs. Evidence-dependent and semantically connected claims are quarantined as UNKNOWN. Reviewed replacements may explicitly supersede stale/conflicting claims; conflicting alternatives are retained in archived responses.

 ## Trust and limits
 
-Source, graph exports and provider responses are untrusted input. The engine does not evaluate their contents. JSON schemas close the input shape, references stay within task scope, and filesystem reads/writes reject symlink traversal. Known secret/dependency/build paths are excluded; `.understand-codeignore` adds repository-specific exclusions. This is not a general secret detector or OS sandbox.
-
-Hash checks prove identity and freshness, not semantic entailment. `source-reviewed` records an accountable judgment; the software cannot prevent someone deliberately lying in that field. Reviewers must inspect cited code, distinguish declarations from execution and preserve unknowns. Generated natural-language details obey the same confidence/evidence contract as summaries.

+# Tool-agnostic code intelligence
+
+Understand Code does not depend on a named code-intelligence implementation.
+
+## Discovery policy
+
+The native Claude/Codex session reads applicable `AGENTS.md`, `CLAUDE.md`, and equivalent host/repository instructions. If those instructions describe an installed code-intelligence, symbol, semantic-search, or code-graph tool, the session may use that tool for retrieval. If several are available, choose the smallest useful structural query for the current investigation. If none is configured or the tool is unavailable or insufficient, fall back to bounded source/file search.
+
+External tool output is retrieval context only. It never becomes evidence by itself and never establishes runtime behavior. Accepted claims continue to require exact current-source evidence through Understand Code's evidence contract.
+
+## Engine boundary
+
+The deterministic engine owns inventory, task scopes, evidence identity, reconciliation, incremental invalidation, and persisted specs. It does not import vendor graph exports, expose vendor-specific CLI flags, write vendor handoff files, or require an external index refresh step.
+
+The native investigation prompt states that repository-configured code-intelligence tools may be used according to applicable agent instructions. This keeps retrieval replaceable without changing the persistent semantic model.

Use any installed code-intelligence, symbol, semantic-search or code-graph tool described there when it helps narrow retrieval; otherwise use bounded source/file search. External retrieval output is context only, never evidence.
+3. Inspect scoped current source and capture exact evidence with `understand-code evidence --repo <repo> <path> --start N --end M`.
+4. Create entities, relations and gaps using the evidence contract. `CORROBORATED` requires independent sources and actual source review; count alone is insufficient.
+5. Save findings outside the source scan and apply with `understand-code apply --repo <repo> --findings <response.json>`.
+6. Review generated Markdown and the diff. `verify` checks source freshness and content integrity; `status` shows pending tasks, deferred scopes and coverage.
 
 ## Feature pages
 
-Semantic entities become pages grouped by kind: features, flows, settings, entrypoints, UI, data, integrations, cross-cutting concerns and architecture. Every page contains confidence, summary, cited source ranges and typed incoming/outgoing change-map links. Optional `details` can provide purpose, runtime steps, permissions, failures or settings effects when the same evidence supports those claims. Unobserved behavior belongs in gaps, not decorative sections.

-For a setting, model the concrete UI/API writer, persistence, cache invalidation, runtime reader and observable UI/API consumers as separate entities and evidence-backed edges. The resulting change map permits traversal in either direction. If a binding is absent, stop that trace at an UNKNOWN gap. Never turn adjacent filenames into a connected runtime flow.

 ## Handoffs
 
-Task-loop agents resolve feature IDs and change maps before fetching source; current source always wins over stale docs. Review agents use semantic impact plus source citations to locate blast radius. After accepted source changes, `update --base <task-base>` prepares affected investigations. Source-dependent claims stay UNKNOWN until reviewed replacements arrive.

-Run bounded specialists in native subagents when the user or environment authorizes delegation. Otherwise perform each investigation sequentially in the current session. Use the session's existing model and tools. The CLI never launches `codex`, `claude`, an SDK, or a paid transport. Automated tests and synthetic evaluation use only prepared fixtures.

 For each task:
 
-1. Inspect the cited implementation and actual callers/registrations, not just filenames or imports. Trace conditional branches, persistence, invalidation, async propagation and observable consumers. For settings, account for writer → validation → storage → cache → reader → UI/API effects; represent missing links as gaps.
-2. Capture each exact supporting range with `evidence --repo <repo> <path> --start N --end M --kind source` (or `test`, `config`, `documentation`). It returns hashes and a stable evidence ID. Read the cited range yourself. Tests are evidence of assertions, not evidence that tests passed.
-3. Return one JSON object using the task's contract. Reuse existing concept IDs. Each summary and relation must be supported by its cited ranges. Use `INFERRED` for incomplete interpretations and `UNKNOWN` for unresolved questions. State architectural intent only when explicit historical/documentary evidence supports it.
-4. Have a separate source review check claims before marking `EXTRACTED` or `CORROBORATED`. Record the reviewer and method honestly; if no independent review is possible, retain `INFERRED`. Two citations do not establish independent corroboration unless their contents do. Preserve contradictory findings instead of choosing the more plausible story.
-5. Save responses outside the target source scan, such as a temporary directory, then run `apply --repo <repo> --findings <response.json>`. Failed validation leaves the spec unchanged. Never edit hashes to fit changed source: run `update`, recapture evidence, and repeat the investigation.

-# Graphify integration
-
-Understand Code consumes an existing `graphify-out/graph.json` node-link export (`nodes` and `links` or `edges`). `--graph <relative-path>` selects another export. It records the input hash and exposes bounded graph neighborhoods to specialist tasks. Node file hints recognize `file`, `source_file`, and `path`. Missing/incompatible graph context never becomes invented structural evidence.
-
-Use graphify/codebase-memory MCP tools for structural lookup and source snippets. Those tools remain the structural engine; Understand Code does not implement a competing call graph. Index source first when authorized, investigate findings, write the Codebase Spec, then refresh the graph with the source plus generated Markdown.
-
-After writing, `_meta/graphify-handoff.json` records the Markdown root and refresh request. `_meta/graphify-semantic.json` is a directed node-link sidecar carrying semantic entities, typed relations, confidence and evidence. Use a compatible consumer to merge it or let Graphify index the Markdown links. Do not replace `graphify-out/graph.json` with the semantic sidecar: that would discard the structural graph.
-
-Graphify installations differ in CLI/API and extraction costs. Consult the installed Graphify skill/tool documentation for its supported incremental refresh. This engine never executes Graphify, invokes an LLM for Markdown extraction, installs dependencies, or assumes an undocumented merge command. If extraction would spend tokens, obtain the authorization required by the user's policy; otherwise retain `pending-external` and state that limitation. A preexisting graph is not necessarily current, and an exported sidecar is not evidence of successful indexing.
