Identity and authority + +- [ ] Assign a stable project ID and title. +- [ ] Declare canonical content roots. +- [ ] Declare authority files. +- [ ] Declare derived cache, changeset, preview, template, and render roots. +- [ ] Define documentation families and allowed relationships. +- [ ] Define proposal writers and operations. +- [ ] Decide which views are public, internal, or restricted. +- [ ] Keep source mutation disabled unless separately designed and authorized. + +Done when every durable documentation fact has one authoritative source and every derived output +can be deleted without losing that fact. + +### 3. Manual foundation + +- [ ] Scaffold or adapt `.docforge/project.toml`. +- [ ] Create at least one authoritative overview node. +- [ ] Assign stable node IDs, families, authorities, statuses, tags, and summaries. +- [ ] Import existing documents without silently changing their meaning. +- [ ] Separate current implementation, approved plans, proposals, and history. +- [ ] Define bounded context profiles for common development tasks. +- [ ] Validate, index, render, and visualize the manual. + +Done when every rendered passage can be traced to a canonical source. + +### 4. Language frontend selection + +For every source language: + +- [ ] Select or implement one frontend. +- [ ] Record its frontend and extractor versions. +- [ ] Define source discovery from authoritative build information. +- [ ] Define stable symbol identities. +- [ ] Define ownership for shared or generated declarations. +- [ ] Define supported node kinds and relationships. +- [ ] Define dependency discovery. +- [ ] State unsupported semantic facts explicitly. + +All frontends emit the same DocForge contracts: + +- `AdapterManifest` inventories fingerprinted extraction units and dependencies. +- `AdapterSourceProjection` owns nodes, relationships, and optional function Logic for one unit. +- `AdapterProjection` provides the deterministic complete rebuild. + +Language metadata may differ. Graph publication, indexing, querying, visualization, and MCP +behavior do not. + +Done when repeated extraction produces the same stable identities without inferred or guessed +facts. + +### 5. Build-system evidence + +#### C and C++ + +- [ ] Use an authoritative compilation database. +- [ ] Preserve target flags, definitions, language standards, and include paths. +- [ ] Resolve headers shared by multiple translation units. +- [ ] Assign shared symbols to one deterministic source contribution. +- [ ] Record compiler-derived project include dependencies. + +#### Rust + +- [ ] Read the Cargo workspace and package graph. +- [ ] Respect packages, targets, features, and conditional compilation. +- [ ] Model crates, modules, traits, implementations, functions, and supported macros. +- [ ] Treat expanded macro output as derived evidence. +- [ ] Record the exact toolchain and extraction backend. + +#### Java + +- [ ] Read Gradle, Maven, or explicit source-root configuration. +- [ ] Respect modules, source sets, language level, and classpath. +- [ ] Model packages, classes, interfaces, records, methods, fields, and supported annotations. +- [ ] Separate authored source from generated and annotation-processor output. +- [ ] Record inheritance and interface implementation. + +Other languages follow the same rule: the language frontend translates authoritative build and +source evidence into the common adapter contract. + +Done when a clean machine can reproduce the same source inventory from declared configuration. + +### 6. Complete reference projection + +- [ ] Extract the complete supported source tree. +- [ ] Generate stable source and symbol nodes. +- [ ] Generate only evidence-backed relationships. +- [ ] Generate optional function-scoped Logic separately from the primary graph. +- [ ] Reject duplicate node or Logic ownership. +- [ ] Reject missing relationship endpoints. +- [ ] Reject unsafe source paths. +- [ ] Record project identity, source hash, counts, and duration. +- [ ] Repeat the build and compare exact output. + +Done when two unchanged complete builds are identical. + +### 7. Incremental compilation + +- [ ] Fingerprint each extraction unit. +- [ ] Record extractor versions. +- [ ] Record direct source dependencies. +- [ ] Invalidate reverse dependents. +- [ ] Remove deleted-source contributions. +- [ ] Treat missing or corrupt caches as cache misses. +- [ ] Publish cache and graph generations atomically. +- [ ] Keep the complete projection as the equivalence oracle. + +Required proof: + +- [ ] cold build; +- [ ] unchanged warm build; +- [ ] implementation-file change; +- [ ] shared-header or shared-module change; +- [ ] added, renamed, and deleted source; +- [ ] build-feature or compiler-setting change; +- [ ] corrupt cache; +- [ ] interrupted extraction; +- [ ] complete-versus-incremental equivalence. + +Done when incremental extraction produces exactly the complete projection. + +### 8. Source and manual integration + +- [ ] Link documented systems to their implementation. +- [ ] Link API reference nodes to extracted symbols. +- [ ] Link roadmap work to affected systems. +- [ ] Link relevant tests and proof artifacts. +- [ ] Report implemented but undocumented systems. +- [ ] Report documented systems without implementation. +- [ ] Keep uncertain links as proposals. +- [ ] Keep source and manual projections independently rebuildable. + +Done when a developer can navigate from a decision to implementation and back without guessing +from filenames. + +### 9. Views and MCP + +- [ ] Configure the generic graph browser. +- [ ] Configure manual, source, API, roadmap, and proof views as needed. +- [ ] Verify search, filters, backlinks, dependencies, impact, and Logic. +- [ ] Generate the exact project-bound MCP command. +- [ ] Select read, proposal, and application capabilities explicitly. +- [ ] Register and reload the client. +- [ ] Call `docforge_bootstrap`. +- [ ] Verify project ID, root fingerprint, adapter version, revision, source hash, and index health. +- [ ] Verify the MCP cannot switch projects or weaken project authority. + +Done when a new session can identify and retrieve the correct project without being told its file +layout. + +### 10. Operating guide and maintenance + +- [ ] Record the authority and progressive-reading order. +- [ ] Explain exact lookup, search, context, backlinks, and impact analysis. +- [ ] Explain proposal, review, approval, and application. +- [ ] Explain cache invalidation and recovery. +- [ ] Explain frontend and adapter version changes. +- [ ] Run complete/incremental equivalence in continuous integration. +- [ ] Add contract tests for newly supported language features. +- [ ] Never hand-resolve generated-output conflicts. +- [ ] Never convert an inferred relationship into canonical truth silently. + +Done when a developer unfamiliar with the repository can use DocForge without loading the entire +manual or inventing another documentation workflow. + +## CLI and MCP boundary + +Initial assessment and scaffolding belong to the CLI because an MCP server cannot be registered +until the project exists.

explains how to turn compiler, parser, build-system, or documentation evidence into a +deterministic DocForge project graph. It covers the design work that is easy to miss when a small +fixture is expanded into a complete repository. + +Use this guide after the repository assessment in +[Project Onboarding](PROJECT_ONBOARDING.md). The onboarding checklist decides whether an adapter +is needed. This guide defines how to build and prove one. + +## Required outcome + +A production adapter must provide one reproducible public graph from authoritative project +evidence. It must not guess facts from filenames, preserve unstable parser identities, publish the +same declaration from several extraction units, or let an incremental cache become a second +source of truth. + +The complete and incremental paths must publish exactly the same: + +- project identity, adapter identity, revision, and source hash; +- nodes and stable node identities; +- relationships and their deterministic metadata; +- function Logic projections and owners; +- source paths and anchors; +- validation failures for invalid input. + +Performance does not relax this requirement. A fast graph that sometimes retains stale or +translation-unit-dependent facts is invalid. + +## The four adapter layers + +Keep these layers separate: + +1. **Evidence discovery** finds the authoritative build and source inputs. +2. **Source extraction** converts one extraction unit into raw, deterministic evidence. +3. **Assembly** resolves overlap and assigns each published fact to one owner. +4. **DocForge publication** validates, caches, indexes, queries, and visualizes the assembled graph. + +DocForge supplies the publication contracts. A language frontend owns the first three layers +because only the frontend understands the language's build semantics, identity rules, generated +evidence, and source ownership. + +The contracts are: + +```python +class MyAdapter: + def load_manifest(self) -> AdapterManifest: ... + def extract_source(self, source: AdapterSource) -> AdapterSourceProjection: ... + def assemble_projection( + self, + manifest: AdapterManifest, + contributions: tuple[AdapterSourceProjection, ...], + ) -> AdapterAssembly: ... + def load_projection(self) -> AdapterProjection: ... +``` + +`assemble_projection()` is optional only when extraction units already have disjoint ownership. +`load_projection()` is always required. It is the clean rebuild and equivalence oracle. + +## Step 1: define authority before parsing + +Write down which tool owns each fact before implementing extraction. + +Typical authorities include: + +| Fact | Suitable authority | +|---|---| +| Source inventory | Build graph, workspace manifest, or declared source roots | +| Active flags and features | Build-system output | +| Declaration identity | Compiler or language-service semantic identity | +| Definition location | Compiler or parser source location | +| Calls and inheritance | Resolved semantic evidence | +| Include or module dependencies | Compiler or build graph | +| Function control-flow shape | A language-aware analyzer | +| Documentation meaning | Canonical documentation sources | + +Do not let a syntax parser overrule a compiler on semantics. Do not infer a resolved call merely +because names match. When the selected frontend cannot prove a fact, omit it or label it as +explicitly derived or proposed. + +Record: + +- frontend and compiler versions; +- build-system and feature configuration; +- supported source and generated-source roots; +- supported declaration and relationship kinds; +- unsupported facts; +- any normalization applied to frontend output. + +Changing one of these rules normally requires an extractor or adapter version change. + +## Step 2: define the extraction unit + +An extraction unit is the smallest input that can be fingerprinted, invalidated, and re-extracted +without hidden state. + +Examples include: + +- one compiler translation unit; +- one module or crate target; +- one Java source set or compilation unit; +- one canonical documentation file; +- one generated API registry snapshot. + +Use the build system's real unit rather than an arbitrary file grouping. One source file is not +necessarily one semantic unit when features, generated files, module resolution, or compiler flags +change its meaning. + +Every unit needs: + +- a stable source ID; +- a project-confined relative path; +- a content or semantic fingerprint; +- an extractor version; +- direct dependencies whose changes can alter its evidence. + +Do not include output paths, temporary directories, wall time, process IDs, pointer values, or +unordered container iteration in any identity or fingerprint. + +## Step 3: prove one bounded extraction + +Begin with one representative unit. Include enough language behavior to expose identity and +ownership problems: + +- declaration and definition; +- nested and out-of-line ownership; +- resolved call; +- inheritance or interface implementation; +- an internal or private symbol; +- one function suitable for Logic extraction; +- one shared declaration imported by another unit. + +The first proof should establish: + +- repeated byte-stable extraction; +- project-root confinement; +- stable source and symbol IDs; +- exact source paths and anchors; +- relationship endpoint validity; +- exact Logic ownership; +- explicit rejection of unsafe or ambiguous build input. + +Do not activate the adapter in a routine project session at this point. A correct single-unit +projection does not prove whole-project ownership. + +## Step 4: design stable identities + +Stable identity is a semantic design decision, not a serialization detail. + +Prefer, in order: + +1. a stable compiler or language-tool symbol identity; +2. a normalized semantic key built from qualified ownership, symbol kind, and signature; +3. a source-qualified identity only for symbols whose language visibility is source-local. + +Avoid: + +- parser object addresses or transient declaration IDs; +- traversal order; +- result-set position; +- source line as the entire identity; +- a display name without namespace, owner, or signature; +- one identity policy for both externally shared and source-local symbols. + +Definitions and declarations of the same externally visible symbol must converge. Anonymous, +private-to-unit, or internal-linkage symbols must remain distinct when the language makes them +distinct. + +Every normalization used inside an identity must be tested against more than one extraction unit. +Some compiler fields change only after a symbol is instantiated, referenced, or fully evaluated. +If such a field is not part of authored identity, remove or normalize it before hashing. + +## Step 5: separate raw evidence from the public graph + +Many semantic tools repeat the same declaration in every unit that imports a header, module, +crate, package, or generated interface. That repetition is valid raw evidence but invalid public +ownership. + +Do not force raw extraction to guess the final owner before the complete dependency inventory is +known. Instead: + +1. extract deterministic raw contributions; +2. inventory the complete current contribution set; +3. assign each shared source or symbol to one deterministic owner; +4. publish each node, relationship, and Logic record once; +5. reject conflicting evidence instead of silently choosing incompatible values. + +The raw contribution cache may contain overlap. The assembled DocForge graph may not. + +### Ownership rules + +Define ownership for every published fact. A common policy is: + +| Fact | Recommended owner | +|---|---| +| Shared source declaration | Deterministically selected dependent unit or declared module owner | +| Unit-private symbol | Its extraction unit | +| Function Logic | The unit owning the exact function definition | +| Containment | The owner of the contained member | +| Call relationship | The owner of the caller | +| Inheritance relationship | The owner of the derived type | +| Source declaration/definition edge | The owner of the source or symbol selected by the adapter | + +The correct policy depends on the language. What matters is that it is explicit, deterministic, +and identical in complete and incremental assembly. + +Relationship metadata also needs deterministic reduction. Repeated evidence locations must not +grow with the number or order of extraction units. Select one stable evidence record, or define a +bounded ordered representation with a documented reason. + +## Step 6: normalize frontend-generated noise + +Whole-project extraction exposes facts that a single fixture will not. Compilers and language +services may emit: + +- implicit template or generic instantiations; +- synthesized methods and bridge functions; +- default constructors or defaulted functions; +- inferred exception or effect annotations; +- generated annotation-processor output; +- macro expansions; +- duplicate declarations with different amounts of semantic completion; +- declarations from libraries outside the project root. + +For each category, choose one policy: + +- publish as authored evidence; +- publish as derived evidence with a stable identity; +- attach to an authored owner without becoming a primary node; +- omit as compiler-use noise. + +Do not keep a field merely because the frontend emits it. If it changes based on whether another +unit uses the symbol, it will break determinism or complete/incremental parity unless normalized. + +Add a regression fixture for every normalization rule. The fixture should demonstrate the +unstable input and the expected stable output. + +## Step 7: compose the complete reference graph + +Run the frontend over the complete supported source inventory and apply the final ownership +partition. + +The composition must: + +- sort units and outputs deterministically; +- converge declarations and definitions; +- preserve source-local identity; +- resolve semantic parents rather than relying only on visual parser nesting; +- reject duplicate node identities with conflicting semantic metadata; +- reject conflicting Logic for one owner; +- reject duplicate source IDs; +- reject missing relationship endpoints; +- retain explicit status when optional Logic analysis cannot parse a function. + +Run two independent complete extractions and compare exact serialized projections or their +canonical fingerprints. + +Record: + +- extraction-unit count; +- node, relationship, and Logic counts; +- relationship counts by important type; +- duration and peak memory; +- output or index size; +- exact fingerprint. + +These measurements establish the reference shape. They are not performance promises across +machines. + +## Step 8: add dependency-aware incremental extraction + +Use authoritative dependency evidence whenever possible: + +- compiler dependency output; +- module or crate graph; +- Maven or Gradle compilation graph; +- generated-source and annotation-processor inputs; +- explicitly declared documentation dependencies. + +The manifest must include every unit that can invalidate a cached contribution. A dependency-only +unit may publish an empty contribution; it still needs a fingerprint and stable ID so reverse +dependents are invalidated. + +The incremental path is: + +1. build the current manifest; +2. compare fingerprints, extractor versions, additions, and deletions; +3. invalidate changed units and their reverse dependents; +4. reuse only valid raw contributions; +5. extract invalidated units; +6. assemble the complete current contribution set; +7. validate the candidate graph; +8. reread the manifest to detect concurrent source changes; +9. atomically publish the cache and index. + +Missing, incompatible, or corrupt cache data is a cache miss. It must never become a partial graph +or replace the last valid index. + +## Step 9: keep the complete path independent + +The full rebuild must not read the incremental extraction cache. Otherwise equivalence compares +the cache with itself and cannot detect stale or incorrectly owned facts. + +The complete path must independently: + +- rediscover the supported source inventory; +- extract every semantic unit; +- apply the same normalization rules; +- apply the same public ownership partition; +- generate the same project metadata and source hash; +- publish the same nodes, relationships, and Logic. + +Raw unpartitioned frontend output is not the equivalence oracle when the incremental assembler +publishes a partitioned graph. Both paths must compare the same public projection shape. + +## Step 10: integrate manual and source projections + +Keep canonical manual and derived source projections independently rebuildable. Compose them at a +session boundary rather than making source extraction rewrite documentation. + +Decide: + +- which sessions receive source nodes; +- which documentation families remain isolated; +- whether active context includes source nodes or manual guidance only; +- how manual nodes link to implementation nodes; +- what happens when required build evidence is absent; +- whether source support is required, optional with a null fallback, or disabled. + +The source graph has no authority to edit runtime code or canonical documentation. MCP, viewer, +cache, and index operation remain bound to one explicit project root. + +## Required proof matrix + +An adapter is not complete until these cases pass: + +| Case | Required result | +|---|---| +| Repeated single-unit extraction | Exact stable output | +| Two independent complete builds | Exact public projection equality | +| Cold incremental build | Every current unit extracted once | +| Unchanged warm build | Zero reparses | +| Implementation/source change | Only the unit and declared dependents reparse | +| Shared header/module change | Every reverse dependent reparses | +| Added source | New contribution appears without stale duplicates | +| Renamed source | Old contribution disappears and new identity follows policy | +| Deleted source | Owned nodes, relationships, and Logic disappear | +| Build flags/features change | Affected units invalidate | +| Extractor version change | Old contributions invalidate | +| Corrupt cache | Clean recovery without partial publication | +| Interrupted extraction | Last validated index remains active | +| Complete versus incremental | Exact equality | +| Cross-session isolation | Unconfigured sessions cannot see the source graph | +| Viewer and MCP retrieval | Exact symbols, relationships, and Logic are retrievable | + +Fixtures must include overlapping shared declarations. A single-file fixture cannot prove +assembly. + +## Performance review + +Measure before and after adding incremental extraction: + +- complete extraction wall time and peak resident memory; +- warm manifest, assembly, validation, and index time; +- raw cache and final index size; +- cache-unit count and cache-hit count; +- node, relationship, and Logic counts; +- checked query latency. + +If warm operation remains expensive, identify whether the cost is dependency discovery, +fingerprinting, assembly, validation, or indexing. Do not hide staleness behind an arbitrary time +window. An optimization must retain same-operation source-change detection or replace it with an +equally explicit freshness contract. + +## Troubleshooting by symptom + +### Node counts change between identical complete builds + +Check for unstable frontend IDs, unordered output, generated declarations, inferred type or +exception information, and source paths containing temporary directories. + +### The same header or module node appears in many contributions + +Keep the overlap in raw evidence and add deterministic assembly ownership.

project-local Python package inference; descriptor fingerprinting; bounded change evidence; restart-required MCP remediation; staged/unstaged deletion contract guidance. -Out of scope: In-process Python module reloading; MCP self-restart; project-specific Git enumeration; canonical source mutation; deployment or publication. -Done when: Every MCP operation rejects added, changed, deleted, missing, or unsafe adapter implementation files before synchronization; derived files outside the declared boundary remain ignored; descriptor changes require restart; deletion semantics remain manifest-owned and staging-independent; the complete DocForge quality gate passes. -Owners: DocForge owns implementation-boundary confinement, fingerprinting, bounded diagnostics, MCP preflight, and

Adapters own the declared boundary and current source-manifest enumeration. Canonical sources and Git staging remain outside this lifecycle guard. -Proof: The focused adapter suite passed 15 tests, including inferred and explicit implementation boundaries, descriptor changes, additions, edits, deletions, ignored derived files, and exact MCP remediation. Strict Pyright passed with no errors or warnings. Ruff lint and formatting, Python compilation, and the HTML/CSS/JavaScript quality gate passed.

The planner contains no Logic operation, so no-AST +bindings can use task context without weakening their existing Logic prohibition. + +Path direction is relative to the preceding traversal node.

The selected design stores one disposable +`generation-diff.json` receipt. It does not add a history database, arbitrary generation +selectors, source text, rendered content, or Logic details. + +Before a build loads current source, it accepts an existing index only when its exact main-file +inode has a matching stable whole-file attestation and no WAL, journal, or shared-memory sidecar. +It then captures that predecessor through an immutable main-file transaction. The capture validates +the SQLite application and schema IDs, project/root/adapter binding, integrity, complete node and +edge rows, Logic aggregate identity, FTS count, metadata hashes and counts, and final file +signature. It never calls normal check or synchronization and never repairs predecessor evidence. + +The final source revalidation now compares exact nodes and edges in addition to source hash, +revision, and Logic. A verified predecessor that maps the same source identity to different graph +content fails before publication as `generation_collision`. This closes a pre-existing adapter +determinism gap found during the generation-diff audit. + +SQLite replacement is now the explicit derived mutation commit point. Whole-file attestation, +cheap source-generation, and generation-diff receipts publish independently afterward. Any +post-commit receipt failure returns `status = ok`, `index = published`, a bounded degraded +publication record, and receipt-stage names. It never rolls back the new index or reports a false failed +mutation. Attestation hashing checks the exact index signature before, during, and immediately +before receipt publication. + +Version-1 diff semantics compare every core `Node` field by stable node ID and exact edge triples. +Node renames are removal plus addition. Edge changes are removal plus addition. Exact summary +counts and a full ordered item-hash collection cover every change. Retained details are +deterministically ordered and independently capped at 1,000 items and 1 MiB with explicit item- or +byte-limit evidence. A first build or untrusted predecessor is a baseline with no fabricated +all-added result. A same-generation reindex republishes the existing meaningful transition against +the new index file identity instead of erasing it with an empty diff. + +The additive public surfaces are: + +- CLI `generation-diff [--limit N] [--cursor OPAQUE]`. +- MCP `docforge_get_generation_diff(limit=None, cursor=None)`. +- Telemetry operations `cli.generation-diff` and `mcp.generation_diff`. + +Public reads do not open SQLite, call `project.load()`, extract an adapter projection, parse source, +check, synchronize, build, or repair. They strictly validate the bounded receipt, compare stable +receipt and index file identities, require two matching cheap source-generation checks, and report +unknown for legacy adapters without that capability. Missing, corrupt, foreign, oversized, +symlinked, stale, or concurrently changed evidence remains a read-only status outcome. + +Generation-diff pagination binds the complete stored receipt hash and effective policy. That hash +already covers project, generation, graph, collection, and committed-index identity. Page size may +change. A replaced receipt returns `stale_cursor`. One top-level pagination object owns the only +cursor. The nested version-1 page uses `receipt_header.stored_receipt_hash` so it never +misrepresents the complete receipt hash as the hash of a partial header. The summary distinguishes +additional retained pages from details permanently omitted by the fixed publication limits. + +Adversarial coverage now includes strict runtime/schema rejection, predecessor attestation and +generation identity, live and synthetic SQLite sidecars, cache-root symlink substitution, +source/sidecar changes during diff preparation, independent receipt failures, and degraded +post-commit identity and durability failures. Focused verification passes the direct, CLI, MCP, +schema, pagination, legacy, incremental no-AST, and zero-work suites.

Four pages reconstruct +all 1,000 retained details in 652,798 bytes at 201.55 ms median.

Final independent publication, contract, and performance audits approve the slice for commit. + +### Deterministic client configuration and read-only doctor + +Client integration remains an explicit machine-local boundary rather than canonical project +content. `docforge configure {codex,claude,openclaw} --project PATH` previews a deterministic +version-1 fragment by default. An optional output path publishes only a standalone fragment into +an existing real directory. Publication is create-only, private-mode, no-follow, bounded, and +conflict-aware. Existing differing client configuration is never merged, replaced, or silently +overwritten. + +Generated commands use the exact current virtual-environment Python executable with isolated +module startup. The binding records explicit read, proposal, or application mode, no-AST policy, +render policy, empty environment, and bounded timeouts. Proposal and application generation fail +closed unless the descriptor declares the required writer and matching applier identity. A generic +CLI cannot reconstruct project-owned adapter composition, so custom adapters return an explicit +unavailable result instead of generating a misleading command. + +Codex and OpenClaw fragments include their verified timeout fields. Claude JSON fragment syntax is +supported, while its timeout representation remains an explicit warning. The configuration result +has a strict JSON schema and canonical plan hash. Diagnostics are additive and remain disabled by +default. + +`docforge doctor --client CLIENT` performs bounded, non-mutating inspection only. It reads the +project descriptor and selected client file through stable, directory-bound, no-follow handles; +parses at most 1 MiB and 256 server entries; selects at most one exact project binding; validates +the closed server argument set; checks executable, capability, declared authority, no-AST, +timeouts, environment-key names, and tool-filter presence; and performs only a stat-level index +presence check. It never loads canonical sources, opens SQLite, starts MCP, executes the configured +command, synchronizes, builds, renders, starts a viewer, or writes client configuration. + +Doctor reports healthy, degraded, or unhealthy with stable process exit codes 0, 1, and 2. Secret +environment values are parsed only to enforce bounded string limits and are never returned. +Unknown or unverified client tool filtering, Claude timeout representation, implicit legacy +capability mode, shadowed authority, and missing disposable indexes are warnings. Unsafe paths, +malformed matching entries, unexpected executables, wrong project roots, invalid authorities, and +missing configuration are failures. + +The first benchmark smoke failed for the correct product reason: its disposable doctor fragment +used the shared path `/tmp/doctor-codex.toml`, where a previous run had left different content. The +harness now creates a project subdirectory inside one unique temporary root and places the client +fragment beside it. This preserves create-only conflict safety and makes every run disposable. + +The final pre-commit 1,000-node audit sample passes every provisional Milestone 2 gate. Task +context reconstructs 1,000 candidates as 108 cited evidence records and 892 explicit bounded +omissions across 11 pages in 703.808 ms. Generation diff reconstructs 1,000 changed details across +10 pages in 427.450 ms. Maximum pages remain below the 200,000-byte MCP budget; generation diff +uses 199,566 bytes and proves that diagnostics are discarded before the primary result. Isolated +peak RSS is 86,168 KiB. + +Configuration preview now includes a bounded real import probe of the exact isolated interpreter, +so its provisional single-sample latency is about 315 ms rather than the earlier sub-millisecond +derivation-only figure. Doctor remains below 1 ms on generated disposable configurations. +Every configuration and doctor hidden-work counter is zero. + +The aggregate `make gate` includes the Milestone 2 smoke benchmark. The frozen candidate passes +205 tests and 120 schema subtests, strict warnings, Ruff, formatting, Pyright, web checks, +compilation, lock and dependency checks, package builds, and all three milestone smoke benchmarks. +Three independent final audits approve client publication and policy binding, doctor fail-closed +behavior, and benchmark/contract coverage.
