# Production readiness roadmap

Status: Windows v0.1.5 published and installed; Linux v0.1.4 previews published. Broader production gates remain open. Windows VM tests use CPU only.

Karl's release priority, 2026-10-13: publish a usable first Windows version and
install it on DEV-WIN11 now. Extensive platform/GPU, clean-machine, signing and
large-library checks are deferred follow-up, not blockers for this initial
release. Keep their evidence and unchecked production gates intact.

Karl's current improvement priority: music relevance, precise spoken-passage
timestamps and irrelevant results when the requested content is absent. The
million-record lexical benchmark is deferred while this quality work proceeds.
Google EmbeddingGemma 2 remains the main text/image/audio/video search model.

- [x] Run frozen actual Google music metadata diagnostics: separate fields improved
  known two-file music memories from 2/4 to 4/4; no-answer remained 5/5 failing.
  This is hypothesis evidence, not independent production validation.
  See [music evidence](MUSIC-METADATA.md).
- [x] Validate the tag hypothesis on frozen unseen licensed music plus fixed mixed
  distractors: 8/14 → 11/14 with original tags, one genuine regression; misleading
  tags fell to 5/14. Missing tags exactly preserved media-only results. No-answer
  remained 4/4 failing. See fixtures/music-validation-v1/README.md.
- [ ] Improve and integrate metadata evidence with source citations/guards and full
  mixed regression; unconditional field-max policy is not accepted as universal.
- [x] Evaluate pinned compact multilingual local reranker: quantized serial/batch
  parity failed; F32 parity passed but six-pair warm cost missed the 200 ms target.
  No suppression/default integration. See LOCAL-RERANKING.md.
- [x] Implement exact artist/title constraints in shared storage, lexical/ANN
  eligibility, CLI/MCP and desktop controls; metadata-only search skips inference.
  Unit/lifecycle evidence is recorded separately from actual model validation.
- [x] Actual Google CPU constraint integration passed with genuine tagged WAVs,
  semantic/hybrid limit-one retrieval, empty absent identities, no-inference
  metadata lookup and warmed lifecycle refresh; see [evidence](MEDIA-CONSTRAINTS.md).
- [x] Publish and install Windows 0.1.5 with exact music filters, verified public
  bytes, source/runtime provenance and actual CPU startup/upgrade; see
  [release evidence](WINDOWS-0.1.5.md). Native interaction and other OS gates stay open.
- [x] Evaluate finer source-preserving local ASR timing with actual Google retrieval:
  the frozen VAD + DTW combination completed with all five sources retained and
  improved strict start points from 4/8 to 6/8. Rejected ordinary-token and ungated DTW runs remain
  preserved; no partial-pool scores were accepted. See SPEECH-DTW.md.
- [ ] Validate independent speech/languages and integrate accepted alignment with
  model setup, packaging, cancellation, source guards and shared engine clients.
  - [x] Implement isolated local recognition, independent raw/speech completion,
    verified excerpts, desktop asset setup and CLI/MCP support; structural and
    actual decoder-clock checks passed. See [integration](SPEECH-INTEGRATION.md).
  - [x] Current CPU worker processed real English/German recordings from Unicode
    paths and reused loaded recognition contexts; this is functional evidence,
    not independent retrieval or word-timing accuracy.
  - [x] Genuine shared-service ASR/Google lifecycle passed: verified speech
    excerpts, zero raw reencodes through policy failure/retry, and retained
    query reader; [proof](SPEECH-INTEGRATION.md).
  - [ ] Run genuine shared-service Google lifecycle and frozen independent query
    controls; stage and deliver the normal hardware-detecting runtime.
- [ ] Validate richer no-answer evidence on new independent positive/negative data; do not retune the failed universal cosine cutoff on old held-out results.
- [ ] Integrate accepted improvements into shared engine/UI/headless clients with verified setup, lifecycle and CPU performance evidence. Diagnostics alone do not raise the media quality rating.
- [x] Publish v0.1.0 Windows installer/checksum, verify public download bytes,
  install on DEV-WIN11 and leave the app running with a desktop launcher.
- [x] Publish Windows desktop v0.1.1 with single-instance handling; verify public
  bytes and isolated genuine Google CPU launch. Existing user installation is
  not automatically upgraded. See [release evidence](WINDOWS-0.1.1.md).
- [x] Publish Windows desktop v0.1.2 with incomplete AI-answer rejection;
  verify public installer/checksum bytes and isolated genuine CPU package launch.
  See [release evidence](WINDOWS-0.1.2.md); user installation not auto-upgraded.
- [x] Publish Windows desktop v0.1.3 with isolated document processing and bounded media previews; installer helper and isolated CPU startup verified. See [evidence](WINDOWS-0.1.3.md). Native UI playback and upgrade checks stay open.
- [x] Publish the Linux x86-64 headless preview with current query-role runtime,
  verified public bytes and genuine document/code/audio CPU archive checks on
  Ubuntu 24.04 WSL. See [headless evidence](LINUX-HEADLESS.md); desktop, GPU and
  broader distribution compatibility remain open.

## Required product scope (user clarification)

- Desktop UI is primary; semantic setup/indexing/search must require no terminal.
- Google EmbeddingGemma 2 is the required production model, matching DigUp.
- Local document, image, audio and video search are required product milestones.
- A separate CLI-only build supports headless Linux without desktop dependencies.
- Production automatically uses available hardware acceleration with CPU fallback;
  this Windows VM is tested in forced-CPU mode only.
- Installer ships the native worker. First launch automatically downloads/verifies
  missing model files and manages indexing in the UI; no terminal setup is required.
- Earlier MiniLM proof is an experiment and does not satisfy the model requirement.
- First interaction must be responsive: prepare indexes and a real Google query
  in the background, retain ready sessions, and show immediate keyword results.
  Model download and initialization must have honest progress and retry states.

## 1. Search foundation
- [x] Rust workspace, reusable engine, CLI, versioned SQLite storage.
- [ ] Filename/path and ranked full-text retrieval with strict filters.
- [ ] Safe folder discovery, exclusions, bounded extraction, passage locations.
- [ ] Incremental updates, rename/deletion reconciliation, crash recovery.
- [x] Persistence and filesystem lifecycle integration tests (Windows CPU).

## 2. Document and semantic retrieval
- [x] Text, Markdown, code, PDF and DOCX extraction with real fixtures (Windows CPU).
- [ ] Validate actual embedding model artifacts, license, CPU runtime and quantization.
- [ ] Versioned embeddings, ANN index, exact-match priority and hybrid fusion.
- [ ] English/German relevance corpus and measured top-10 recall.
- [ ] Atomic model/index replacement and resumable persistent work queues.
- [x] Completed-source manifests with title/model/window policy keys and
  citation remapping; reuse only verified complete document/media groups.
- [ ] Durable generation tasks, crash resume and final corpus reconciliation;
  see [incremental semantic design](INCREMENTAL-SEMANTIC.md).

## 3. Desktop
- [x] Image preview pixel ceilings use actual decoded format; a real PNG renamed
  `.jpg` cannot receive the larger JPEG allowance (Windows CPU regression).
- [x] Replace lifetime-growing native media asset grants with bounded preview
  access, including range limits, stale-source handling and selection/reload tests.
  Do not use permanent forbidden patterns as revocation.
- [ ] Validate native custom-protocol image/audio/video playback and seeking on
  release platforms; structural Windows CPU tests alone do not close this gate.
  See [preview contract and evidence](MEDIA-PREVIEW.md).
  - [x] Linux WSL native Rust preview tests (9/9) and full desktop suite (45/45)
    passed on the immutable implementation snapshot; actual playback remains open.
- [x] Official single-instance transport with isolated explicit profiles;
  Windows CPU duplicate launch exits without a second query worker.
  See [launch evidence](SINGLE-INSTANCE.md); visual focus and other OS checks remain open.
- [x] Persisted solid/glass/frosted appearance and bounded background tint;
  opaque reading surfaces, serialized settings updates and high-contrast fallback.
- [ ] Verify native glass visually on Windows 11 22H2+; macOS/Linux currently
  use an explicit opaque fallback. Native compositor performance remains open.
- [ ] Tauri shell, accessible keyboard search, progressive results and previews (shell built; UI interaction verification pending).
- [ ] Folder selection, exclusion controls, resource budgets and indexing status.
- [ ] Global shortcut, opening/revealing source files, PDF page navigation.
- [ ] Watchers and reconciliation across Windows, macOS and Linux.
  - [x] Native notification coordinator, bounded targeted reconciliation,
    periodic verification and CPU-tested Windows/Linux create/update/rename/delete.
  - [x] Durable same-stat media hint invalidation, guarded metadata writes and
    real Google reindex/reuse regression; owned decoder scratch avoids feedback.
  - [x] Native Linux watcher-driven UI refresh, independent refresh timing,
    temporary selection restoration and explicit selection override.
  - [ ] Native macOS events, Windows/macOS watcher-driven UI refresh and representative storage
    failure/contention checks; see [automatic indexing](AUTOMATIC-INDEXING.md).

## 4. Media
- [x] Genuine Google image, audio and video embeddings integrated with the shared
  search service and CPU-tested FFmpeg decoding; music tags and duration filters.
- [x] Frozen independent media corpus with retrieval, timestamp, negative-query
  and indexing-cost measurements (see MEDIA-QUALITY.md).
- [ ] Improve precise spoken-passage localization, music hard negatives and
  calibrated handling of queries without a relevant match.
  - [x] Prepare bounded CPU speech diagnostics and test process failures,
    timestamp units and frozen-label scoring; see [speech proposal](SPEECH-ALIGNMENT.md).
  - [x] Build a pinned CPU VAD diagnostic with explicit one-thread inference,
    native error detection and full probabilities; actual Silero silence/input
    contracts passed. Media quality comparison remains open (see SPEECH-VAD.md).
  - [x] Complete frozen five-source VAD/base-ASR/Google CPU diagnostic:
    component costs decreased, but localization stayed 4/8 point and 6/8 overlap;
    no production default selected. Independent held-out media quality remains open.
  - [ ] Run genuine local speech candidates, Google transcript retrieval and
    held-out English/German/music/no-speech checks before selecting a default.
- [ ] Package and verify decoders on every release OS; test production acceleration.
- [x] Native Linux x86-64 pinned decoder provenance, startup, WAV probe and CPU
  decode; broader codec/ABI coverage and desktop packaging remain open.
- [ ] CPU OCR, image retrieval, audio transcription, video segment locations.
- [ ] Isolated extraction workers with timeouts and resource ceilings.
  See [implementation subgoals and provenance contract](EXTRACTION-ISOLATION.md).

## 5. Release gates
- [x] Normal worker build/staging defaults to hardware-detecting auto with CPU
  fallback; missing Vulkan/glslc fails configuration rather than hiding GPU loss.
- [ ] Provision release-build GPU SDKs and verify one hardware-detecting package
  per OS/architecture, including missing-driver fallback and dependency closure.
- [x] Windows-x64 official pinned SDK copied into workspace with verified cache
  provenance; universal CPU/Vulkan worker and embedded-frontend desktop built.
- [x] Real Windows archive integrity, packaged decoder startup and auto-mode
  CPU inference with a controlled no-GPU-provider registry; Google CPU parity.
- [x] Normal Windows x64 archive includes baseline/optimized CPU dispatch,
  OS AVX-state guards, shared app-local MSVC CRT and hashed DLL inventory;
  real optimized and baseline-only package inference passes in the CPU VM.
- [x] Normal native Linux x86-64 CPU/Vulkan worker build, hashed 19-library
  staging and genuine optimized/baseline-only CPU code-query inference outside
  the build tree; desktop, ABI/older-hardware and GPU validation remain open.
- [x] Actual Linux automatic CPU fallback with Vulkan loader, ICDs/drivers and
  GPU devices absent in a verified private namespace; no GPU provider loaded.
- [ ] Verify CPU dispatch on older physical CPUs and a clean Windows machine;
  dependency inspection and baseline execution on a modern VM are insufficient.
- [ ] Actual missing/incompatible GPU drivers, precision, device loss and memory
  pressure on release hardware; native GUI and clean-machine archive launch.
- [x] Windows desktop archive packager includes explicit runtime/helper files
  and notices, checks architecture and records per-file checksums; excludes
  model caches and user data. Controlled packaging regression tests pass.
- [x] Embedded-frontend Windows Release archive launches outside the source tree
  with isolated data and a ready real Google CPU semantic generation.
- [ ] Verify native interactions, clean-machine prerequisites, GPU dependencies,
  upgrades and signing.
- [x] Preflight native license and the complete offline Google model pair before
  modifying staged resources; corrupted/missing assets preserve existing worker.
- [x] Transactional resource staging, verified copied bytes, process locking,
  interrupted-copy/swap recovery and backup preservation on failed rollback.
- [x] Normal Windows/Linux source-build provenance gate before staging and
  archive preparation; stale inventories preserve existing resources/packages.
  Actual normal builds verified. See [runtime provenance](RUNTIME-PROVENANCE.md).
- [x] Prepare static macOS Metal inventory and mandatory normal-profile staging,
  with embedded-source/dependency/architecture metadata regressions.
- [ ] Execute native macOS runtime build, relocation and genuine CPU/Metal
  inference; fixture metadata tests do not satisfy this gate.
- [ ] Verify power-loss durability and release-tool interaction with resource
  directory swaps on each OS; fault-injected process interruption is narrower.
- [x] Shared monotonic Basic/Debug search metrics, granular bounded engine traces,
  actual worker query diagnostics, and headless JSON performance output.
- [ ] Verify detailed performance UI interaction on native desktop platforms;
  repeat overhead measurements on representative libraries and hardware.
- [ ] Formatting, lint, tests and security/dependency review.
  - [x] Inventory locked Rust/npm advisories; prepare byte-verified compatible
    upstream GLib iterator backport for the Linux desktop dependency graph.
  - [x] Execute optimized Linux GLib backport regressions: three tests and the owner-lifetime compile-fail test passed; stored log hash and all 121 upstream source files reverified.
  - [x] Native Linux 0.1.4 desktop build and packaged CPU startup use the selected local GLib backport; native graphical interaction remains unchecked.
  - [x] Execute cargo-audit 0.22.2 against both current lockfiles with a fresh RustSec database and warnings denied; zero vulnerability-class findings, two tracked maintenance notices and exit 1. See DEPENDENCY-REVIEW.md.
  - [ ] Complete native graphical interaction and broader native runtime/source security review. No broad security gate is closed by these narrow checks.
- [ ] CPU benchmarks: filename p95 <50 ms/1M records; text <150 ms/100K documents; semantic <500 ms on declared hardware.
- [ ] Measure cold start, indexing throughput, RAM, disk and idle CPU.
- [ ] Record the very first foreground query and distinct unseen queries after
  production background preparation; report initialization time separately.
  Warm p95 alone does not satisfy the first-use requirement.
- [ ] Test migrations, interrupted work, invalid documents, inaccessible/offline roots and cloud placeholders.
- [ ] Automated native build matrix and documented supported cross-compilation paths.
- [x] Native Linux headless workspace tests: 106 passed, 18 explicitly ignored.
- [x] Native Linux Google text/code/media reference parity and service
  lifecycle/rebuild recovery: seven genuine CPU integration tests passed.
- [x] Unsigned Linux x86-64 headless archive: verify extracted checksums/modes,
  mixed document/code/audio indexing, decoder discovery, semantic retrieval,
  line citations and strict filters outside the source/build directories.
- [ ] Execute native Linux video/codec coverage and Linux desktop/macOS
  platform tests; create Windows/macOS/Linux installers.
- [ ] Signing/notarization configuration, upgrade/rollback validation, release instructions.

## 6. Local agents and optional answers

- [x] Read-only MCP stdio server using the shared search service, persistent
  Google worker, structured filters, source citations and measured search stats.
- [x] End-to-end MCP initialization, discovery, search, invalid-input and
  source-access tests; no protocol text mixed with diagnostic stdout.
- [x] Installable agent skill and copyable MCP client configuration, with clear
  database scope, readiness and untrusted-source handling.
- [x] Optional OpenAI-compatible summaries/questions, disabled by default;
  explicit selected-source action, endpoint disclosure, bounded payloads,
  credentials kept out of persistent settings, diagnostics and error messages.
- [x] Verify real HTTP wire format against a local test endpoint; reject invalid
  settings, stale sources and unauthorized citations; preserve search on failure.
- [ ] Native UI interaction and chosen-provider quality/latency checks before
  claiming production-ready answers or compatibility with every provider.

## 7. EmbeddingGemma 2 efficiency

Audit and measured priorities: [EMBEDDINGGEMMA2-AUDIT.md](EMBEDDINGGEMMA2-AUDIT.md).

- [x] Audit actual required model, task prefixes, pooling/normalization, native
  sequence processing and CPU/runtime policies against primary sources.
- [x] Record real CPU 1/2/4-thread query/first-use/document measurements and
  paired repeated-query/filter-change results with unchanged retrieval evidence.
- [x] Bounded provider-scoped actual-query vector LRU with accurate cache traces;
  preserve filtering, source freshness, failures and actual warmup probes.
- [x] Bounded shared prepared-ANN handoff before SQL activation; retain query
  model/LRU and readiness across publication. Actual CPU first new query has
  no foreground graph load; [recovery/handoff evidence](RECOVERY-AND-HANDOFF.md).
- [x] Reduce semantic settle delay to 120 ms and retain old ready generation
  during rebuilding; test initial-generation and activation readiness boundaries.
- [x] Bound whole IPC write/read deadlines and recover from a nonreading helper;
  CPU-only real helper-process regressions cover blocked writes and responses.
- [x] Windows x64 baseline/optimized CPU runtime selection and OS AVX-state
  checks, verified with real packaged baseline and optimized inference.
- [ ] Validate CPU selection on older hardware and remaining architectures.
- [x] Completed-source vector reuse in atomic schema-7 generations, verified
  with genuine Google CPU document/code/image/audio/video fixtures.
- [x] Resume completed staging sources after failed publication; incomplete
  groups are purged under the OS build lock before retry.
- [x] Pre-inference staging pruning with compatible rename remapping and
  100,000-chunk storage boundary; late validation after ANN preparation.
- [x] Exact parser-input SHA provenance and same-metadata overwrite detection
  on normal rescans; stale/missing agent excerpts fail closed.
- [x] Actual Google CPU same-metadata text mutation before/during inference:
  reject publication, rescan without metadata workarounds and reuse unaffected vectors.
- [x] Abrupt owned CLI termination after a committed partial audio chunk;
  resume completed documents and reencode unfinished media without duplicates.
  Process termination does not prove power-loss durability.
- [ ] Concurrent deletion/media mutation, component-policy reuse and
  indexing/foreground measurements.
  See [INCREMENTAL-SEMANTIC.md](INCREMENTAL-SEMANTIC.md).
- [ ] Benchmark genuine token-budgeted multi-sequence batching and isolation.
- [ ] Implement and measure shared foreground/indexer resource budgets/priority.
  - [x] Shared inference admission, foreground priority between background
    encodes, total-thread settings migration and retained warm sessions on save
    failure; real Google CPU overlap regression passed on Windows.
  - [ ] Measure representative mixed-media contention, single-thread latency,
    extraction/decoder/ANN work and native UI p95 before closing this gate.
- [ ] Attribute startup cost; measure smaller query context and selective encoders.
  - [x] Query-only 512-token context in the normal worker, desktop/CLI/MCP
    integration and actual Windows CPU parity/boundary/reference tests.
    Paired samples reduced private commitment by 183 MB; resident memory and
    cached startup were essentially unchanged. See [QUERY-CONTEXT.md](QUERY-CONTEXT.md).
  - [x] Native Linux query-context and CLI/MCP cited-result checks, with six
    paired CPU process measurements; resident/PSS memory effectively unchanged.
  - [ ] Verify native macOS, GPU parity and updated installed packages.
  - [ ] Evaluate text readiness before the larger media projector finishes
    downloading; preserve verified assets and honest media setup status.
    - [x] Typed backbone/projector verification callbacks with full-pair setup
      semantics preserved; 16 asset tests passed, including gated media download.
    - [x] Integrate explicit text/media coverage, retained query readiness and
      media retry status across engine/desktop; genuine CPU promotion reuses
      identical document vectors with zero document re-encodes.
      See [early text setup](EARLY-TEXT-SETUP.md).
    - [x] Native Linux CPU first use during genuine delayed media download,
      failure/retry and promotion; actual first-input timing recorded separately.
      Focused activation retest preserves selection and query process, records
      fresh timing/current generation after idle. Windows/macOS checks stay open.
- [ ] Buffered bounded media IPC and linear UTF-8 source-window offset processing.
- [ ] Evaluate 256d MRL and content-specific vision budgets on independent data.
- [ ] Validate GPU precision, synchronization-aware timings, parity and fallback
  on actual accelerator hardware; CPU VM checks do not satisfy this gate.

Completion requires recorded evidence; targets are not measured results.

## 8. Source-code retrieval

- [x] Shared code classification, strict lexical/ANN filtering before top-k,
  expanded source/build formats, bounded overlapping passages and actual lines.
- [x] Desktop Code scope, CLI `--code-only`, read-only MCP `code_only`, immutable
  scope snapshots and code-format-preserving previews.
- [x] Google's CodeRetrieval query instruction, explicit worker capabilities,
  task-scoped vector cache and genuine CPU prompt/debug parity.
- [x] Exact original source windows when Google's tokenizer normalizes text;
  verified UTF-8 offsets, full tail coverage and actual token-budget checks.
- [x] Schema-11 migration schedules unchanged source for re-extraction; tests
  preserve ordinary documents and filename availability through the upgrade.
- [x] Frozen 9-query real Google CPU regression with lexical comparison,
  ordinary-document exclusion and exact MCP source excerpt verification.
- [ ] Evaluate independent real repositories, more languages, overloaded
  symbols, near-duplicate routines and queries with no relevant implementation.
  - [x] Audit mixed-task routing and eligibility cache behavior; see
    [routing audit](RETRIEVAL-ROUTING.md).
  - [x] Complete the unchanged 32-file/91-query real Google CPU mixed baseline:
    Code scope 14/14 top-1 versus All files 10/14; all 10 no-answer queries
    returned candidates. See [mixed quality](MIXED-QUALITY.md).
  - [ ] Measure task fusion and cache cost against independently reviewed
    held-out data, preserving the frozen diagnostic for regression comparison.
    - [x] Freeze disjoint bilingual text/code calibration and held-out labels
      after independent AI review; verify exact Git-preserved source/label bytes.
    - [x] Add a shared-engine calibration-only runner retaining raw cosine,
      lexical provenance, hybrid ranks and atomic incomplete evidence.
    - [x] Execute the frozen calibration-only baseline with genuine Google CPU
      inference; preserve raw results and leave held-out requests unevaluated.
    - [ ] Freeze the proposed relevance policy, then
      evaluate held-out queries without tuning against their results.
  - [x] Explicit English/German code intent vetoes exclusive audio routing;
    actual Google CPU regression preserves code among qualifying audio candidates.
- [ ] Validate code search UI interaction on native Windows/macOS/Linux and
  actual GPU hardware. Tiny CPU fixtures do not close those release gates.

## Completed foundation details

- SQLite FTS5 with exact filename priority, text snippets and strict filters.
- Default directory exclusions and protection against indexing the index itself.
- Metadata reuse, atomic root reconciliation and schema-v1 migration coverage.
- Actual CLI process integration tests and independent-reader concurrency test.
- TypeScript desktop frontend build and dependency audit passed; native validation underway.
- Initial README commit pushed to Gitea main via protected Infisical injection.
- Native desktop build and guarded opening tests passed on Windows.
- Genuine multilingual CPU model proof: 5/6 top-1, 6/6 recall@3; quality gate remains open.
- Native Rust CPU embedding adapter verifies pinned model/tokenizer assets;
  integration with the search index and platform runtime packaging remain open.
- PDF page and DOCX paragraph matches persist; corrupt/encrypted/over-limit
  documents remain filename-searchable and report extraction errors.
- CLI exposes folder/type/size/date filters and additional directory exclusions.

The partial features above do not close broader production milestones such as
crash-resumable jobs, fuzzy retrieval, watcher reliability or performance targets.

## Document worker follow-up

- [x] Shared PDF/DOCX process adapter, exact-byte post-parser validation, cancellation rollback and desktop resource discovery. See [evidence](EXTRACTION-ISOLATION.md).
- [x] Build and require the extraction helper in Windows release packages; extracted installer helper passed genuine PDF indexing.
- [x] Build, verify and publish updated Linux headless archive with its required helper; genuine relocated PDF/DOCX and Google CPU checks passed.

## Current shared-code check

At source `fd67906`, Windows CPU-only validation passed strict
`cargo clippy --workspace --all-targets --locked -- -D warnings` and workspace
formatting. The public v0.1.3 tag resolves to the recorded application source
`3bf95583533ce44021c8ecd9733f32062488976e`.

A bounded Infrastructure Ops System-catalog query for macOS test availability
returned no registered Mac workstation. No Mac network availability or native
build was inferred from that lookup; macOS execution gates remain unchecked.

- [x] Current native Linux desktop release compilation and local loader closure on Ubuntu WSL; [evidence](LINUX-DESKTOP.md).
- [x] Linux desktop relocated normal resource discovery and CPU query-worker startup under an owned software-display test; no native UI interaction claim.
- [x] Publish Ubuntu 24.04 x86-64 Debian desktop preview; verify public bytes and extracted package CPU startup. See [evidence](LINUX-DESKTOP.md).
- [ ] Linux desktop graphical interaction and broader distribution compatibility.

## Rust audit and goal review, 2026-10-13

- [x] Publish Windows 0.1.6 and optional CLI/MCP client; verify public full bytes and install/start the normal distribution under CPU-only VM constraints. Settings preserved and database integrity checked. See [delivery evidence](WINDOWS-0.1.6.md).
- [x] Make local speech/media search usable with visible experimental status, preserving Google EmbeddingGemma 2 retrieval and source locations.
- [ ] Resolve absent-content false positives and establish broader music/speech quality and precise timestamp evidence. Preserve the failed longer-source evaluation; do not promote its score.

- [x] Audit core/service and desktop/CLI Rust boundaries; avoid unnecessary naming/module churn.
- [x] Correct valid pre-1970 filesystem timestamps across indexing, source eligibility and previews. Changed crates passed 100 tests (six ignored), desktop 47; strict Clippy and formatting passed. See [audit](RUST-AUDIT.md).
- [x] Publish Windows v0.1.4 with the timestamp correction; verify public bytes, packaged helper provenance and isolated real Google CPU query-worker startup. See [evidence](WINDOWS-0.1.4.md).
- [x] Publish updated Linux headless and Debian packages with the timestamp correction; genuine archived-document CPU search, unchanged rescan and packaged query-worker startup passed. Public bytes verified; [evidence](LINUX-0.1.4.md).
- [x] Protect mixed quality evidence from accidental report overwrite and partial JSON publication; eight evaluator contract tests passed.
- [x] Finish the unchanged frozen mixed regression on the current 0.1.4 engine; independent score recomputation confirms one known routing improvement and no scored regression. All-files positive top-1 74/80, recall@5 80/80; no-answer failures remain 10/10. See [comparison](MIXED-QUALITY-0.1.4.md); independent quality gates stay open.

Initial Windows delivery is complete. Native interaction/upgrade, actual GPU,
macOS execution and independent media-quality work remain real follow-up; the
full production goal remains active. Preserve the detailed unchecked gates above.
