Summary

Adds an opt-in Use on-screen words as vocabulary hints setting under This Mac, modeled on Cotypist's on-device screen-context reading. When a take starts, the Mac captures the window with keyboard focus (system-wide Accessibility focused element matched to its window-list entry, via ScreenCaptureKit), reads its text on-device (Vision, language correction off), and ranks unusual words: names, identifiers, camelCase, acronyms, and words the spell checker does not know. Up to 40 go to the server with the finish request and follow the shared dictionary names as Qwen cleanup (proofreading) hints, so they only use leftover hint budget.

This PR originally fed Whisper's prompt. Main has since moved to Parakeet, which has no vocabulary prompt (an earlier commit on this branch made the feature dormant). This update merges current main and makes the feature live through the Qwen cleanup stage instead:

  • API 4 → 5. FinishGenerationRequest rejects unknown fields, so a v4 server returns 400 when sent screenContextTerms; the client's exact-version gate means client and server must update together. Existing installs keep their stored cleanup prompt (see below).
  • Server stores well-formed screenContextTerms on the record only when text correction is enabled, and appends them after dictionary names in the bounded hint list sent to Qwen. proofreadingHints reflects exactly what Qwen received. Screen terms get less validator authority than dictionary terms: they never join split source words and never get the near-spelling equivalence exemption, so an on-screen word can't make a word-swap free — a repair toward an on-screen spelling must pass the same wording-preservation checks as any other edit (in practice this means names get fixed in sentences of ~5+ words, not in very short ones).
  • Default cleanup prompt now tells Qwen to use a preferred term's exact spelling when a transcript word sounds like or closely resembles one. With the old wording ("use dictionary names only when they match what was said") Qwen received the hints and ignored them in testing below. This only changes the default for new setups; stored prompts are untouched.
  • Client: live toggle (default off), Screen Recording permission row with Accessibility/Screen Recording warnings, capture at take start (never Test microphone, never Inlay's own window, never during secure input, no fallback if the focused window can't be matched, focus revalidated after the screenshot), finish waits at most 500 ms for terms. Terms are never written to disk on the Mac, so post-relaunch reseals send none. History shows the exact terms sent with each take.

Privacy: the screenshot and recognized text never leave the Mac. Emails, URLs, domains, paths, long numbers, and credential-shaped tokens are filtered on-device before ranking (layered: known vendor key prefixes, shape rules, and per-segment spell-check subword coverage with a cap on consecutive uncovered letters). It's a heuristic boundary, not a proof: measured residual leak for random unknown-vendor tails is ≲2% depending on shape, word-salad passphrases are indistinguishable from identifiers, and History shows exactly what was sent.

Does it help? (from the Whisper-era evals)

The original evals (run outside the repo against inlay-engine, whisper large-v3-turbo) measured ranked screen terms cutting WER 30.6% → 12.3% and key-term recall 34.3% → 73.1% across 16 context scenarios, which is why ranked terms rather than raw OCR text are sent. The Qwen path is weaker by construction: it can only respell what Parakeet already transcribed in longer sentences, and only when Qwen proposes it. No equivalent eval has been run for the Parakeet+Qwen path yet.

Verification

  • bun run check, bun run lint, bun run fmt:check, bun run generate:api --check, swift build --force-resolved-versions pass.
  • Isolated dev server with real models (Parakeet/Metal + Qwen MLX, port 8393, separate data dir): same TTS recording sent create → upload → finish with and without terms.
    • Raw transcript both times: "Can you help Merrill with the Zootus migration? Sure it already finished Hoogvliet last week."
    • Without terms: final unchanged ("Merrill", "Zootus").
    • With Merel, Zuidas, Sjoerd, Hoogvliet under the new default prompt: "Merel" applied; record stores screenContextTerms and proofreadingHints lists them after the dictionary names. Zootus and Sure it were not repaired (Qwen didn't propose them).
    • Under the old default prompt wording the proposal was identical with and without terms — hence the prompt change above.
    • Negative paths: 41-term list → 400; newline term → 400; duplicate terms → 400; a lone-surrogate term is dropped and the take completes with the well-formed terms.
  • Not re-verified this round: a desktop take in Inlay Dev with the recommissioned capture (the earlier Whisper-era desktop verification is in this PR's history). The credential filter was exercised against token corpora and adversarial examples through the shipped ScreenContext.terms code with the real spell checker.

Review history

Original rounds: GPT-6.1 Sol, Greptile, CodeRabbit (see earlier comments). This update went through further adversarial Claude/Codex rounds, which found and fixed: credential-token leakage classes, wrong-window capture (frontmost vs focused app, ambiguous frame matches), country-extension domains (Bank.MD) slipping the filename exception, screen terms inheriting dictionary-level validator trust, and a pre-existing validator hole where term joining could merge a negation away ("not able" → "Notable") — joining now never crosses a negation word, for dictionary terms too.

RetriggerView in GreptileConfidence Score: 5/5

No blocking findings remain. The two outstanding previous concerns affect hint coverage and app responsiveness but do not make this PR unsafe to merge.

Findings

  2. P2 Screen ranking blocks the app ▶
Fix with agent prompt
### Issue 1
Sources/InlayCore/ScreenContext.swift:undefined-138
If screen OCR reads `os.Logger` or `package.Type` in a code window, the new lowercase-first-label check treats the identifier as a web address and skips it before vocabulary ranking. Dictation loses spelling help for those identifiers, a non-blocking reduction in hint quality.

Note: If this suggestion doesn't match your team's coding style, reply to this and let me know. I'll remember it for next time!

### Issue 2
Sources/Inlay/System/ScreenContextCapture.swift:69-75
`ScreenContext.terms` runs ranking and spell checks synchronously on `MainActor`. On a dense window, thousands of checks can freeze the controls and delay finishing a take. The timeout in `value(waitingAtMost:)` also needs `MainActor`, so it cannot interrupt this work after 500 ms.

Split ranking into small batches that yield and check the deadline.

For each issue above, determine whether it is valid and should be fixed. If so, fix it directly.

Summary

This PR adds optional on-screen vocabulary hints to Qwen proofreading. Screenshots and recognized text stay on the Mac; selected terms are sent to the server.

  • The Mac can send unusual words from the focused window as hints.
  • Qwen uses on-screen terms as lower-priority proofreading hints.

📝 Walkthrough

The client adds optional focused-window term capture for proofreading. The API advances to version 5 and carries the terms in finish requests and generation records. The server validates and stores the terms, then uses them as separate proofreading hints from dictionary terms.

Changes: Screen-context proofreading hints

Layer / File(s) Summary
Version 5 API contract
Server/api/openapi.yaml, Sources/InlayAPI/API.swift, Sources/InlayAPIWire/Types+Components+Schemas.swift, Sources/InlayAPI/GeneratedShared.swift, README.md, docs/client-server-contract.md
The API version advances to 5. Finish requests and generation records gain optional screenContextTerms. The upgrade guidance documents the version compatibility check.
Focused-window term extraction
Sources/InlayCore/ScreenContext.swift, Sources/Inlay/System/ScreenContextCapture.swift
The client adds OCR and term extraction for focused-window text. The extraction filters candidate terms, ranks them, and applies limits.
Client capture and dictation flow
Sources/InlayCore/InlayConfiguration.swift, Sources/Inlay/InlayController.swift, Sources/Inlay/System/Permissions.swift, Sources/Inlay/Views/PreferencesPage.swift, Sources/Inlay/Views/HistoryPage.swift, docs/architecture.md
The client adds a disabled-by-default setting and permission controls. Eligible dictation sessions capture terms and attach them to finish requests after a wait of up to 500 ms. History displays saved terms.
Server term validation and proofreading input
Server/src/domain/dictionary.ts, Server/src/generation-service.ts
The server validates and stores terms when text correction is enabled. Proofreading input combines dictionary and screen terms while preserving their separate roles.
Correction evaluation and prompt
Server/src/domain/correction-runtime.ts, Server/src/domain/correction-worker.ts, Server/src/domain/correction.ts, Server/api/default-proofreading-prompt.txt, Sources/InlayAPI/GeneratedShared.swift, docs/text-correction.md
Correction evaluation receives the two term sets separately. Dictionary terms remain trusted for matching and validation; both sets are checked for occurrence-count changes. The prompt guidance and documentation describe preferred-term use.

Suggested reviewers: bmdavis419

Priority: ➖ Normal

Merge Risk: 🔵 Low · up to 22986

The feature is opt-in and the remaining problems are small: a wrong plural in History, a documentation sentence that overstates how screen hints are validated, and a deliberately conservative filter that may drop some code identifiers from hints. None of these threaten data or availability. They are worth a quick fix or acknowledgement but should not block merge.

Security architecture risk: 🟡 Moderate · up to 3f84f

The optional screen-reading feature can transmit domain names that its privacy rules say will remain on the device. Exposure is limited by opt-in, focused-window capture, permission checks, and small term limits, but those safeguards do not close the filtering gap.

Retained concerns

  • Medium · security · inferred: The new screen-to-server privacy boundary permits domain data through file-name exemptions. A bare host-and-port such as Portal.md:443 bypasses the port check, and Portal.md can be ranked, transmitted, and persisted despite the documented promise that domains are never sent. This requires enabled capture and visible text in the focused window; it does not expose raw screenshots or entire OCR output.
Security review details

Security Blast Radius

  • inferred — The new disclosure surface is selected text visible in one focused window during opted-in takes. Successfully selected terms reach the configured server's generation archive and recognition input. An attacker influencing that window can influence candidate terms without holding server credentials, but needs the user's enabled feature, permission, and take initiation. Exposure is bounded per take, not necessarily across repeated takes; downstream reader and deployment scope were not independently established.

Security Findings and Attack Paths

  • inferred — If OCR produces Portal.md:443 in an enabled take, the uppercase-enabled file exception skips domain and port rejection. Portal.md then satisfies dotted-identifier ranking and server formatting validation, allowing domain data into persistent metadata and, when capacity permits, recognition vocabulary. This is a source-derived privacy bypass, not a demonstrated production exploit or a raw-screen disclosure.

Trust Boundaries and Controls

  • observed — The client is the enforcement point for screen-content exclusions. The server filters whitespace and unsafe Unicode control categories and caps added recognition vocabulary at 8,192 aggregate terms and 384 KiB, but does not reapply email, path, or domain exclusions. Consequently, server bounds contain size and formatting exposure without restoring a missed client privacy exclusion.

Resilience and Maintainability Implications

  • observed — Capture timeout or cancellation resolves unfinished capture without terms. Server finish validates receiving state and audio completeness before sealing, preserves an already sealed record on matching repetition, and marks storage failures terminal with partial-artifact cleanup. The client treats an interrupted seal response as potentially accepted, avoiding an assumption that interruption erased submitted metadata.

Hardening Proposals

  • proposed — Make file-name exemptions subordinate to the chosen domain and port privacy policy, conservatively handling ambiguous host-like strings. Validate the policy with case-varied country domains, host-and-port strings, legitimate file locations, and OCR-altered address forms. Preserve the distinction between intentionally submitted names and content promised never to leave the device.

P1 security Some domains are sent A domain ending in a listed file extension, such as team.md, skips the domain check. Even team.md:8443 is retained as team.md because this branch also skips the port check. One occurrence ranks highly enough to be sent and stored, despite the promise that domains stay on the Mac.

Fixed in b1d59c2. The capture now reads the Accessibility focused window (the same focus that delivery uses) and matches the same app's window-list entry by frame, at any layer, so floating editors and panels supply their own hints. It falls back to the frontmost normal window only when the focused window can't be read.

Fixed in cbabe3b. Screen hints do need Accessibility to find the focused window, and the frontmost-window fallback was removed deliberately after the CodeRabbit finding about reading the wrong window. Preferences now warn "Allow Accessibility below so screen hints can find the window you are dictating into." when the setting is on without Accessibility, and the architecture doc lists both permissions.

Screen terms now follow dictionary names as Qwen proofreading hints
(dictionary keeps priority in the shared budget and full validator
trust; screen terms get neither source joining nor equivalence).
API bumps 4 -> 5. Default cleanup prompt now tells Qwen to use
preferred spellings for sound-alike words, without which it ignores
the hints.

Hardening from adversarial review: credential-shaped tokens are
filtered on-device (vendor prefixes, shape rules, per-segment
spell-check coverage with an uncovered-run cap), the captured window
is the system-wide focused window with revalidation and ambiguous
frame matches fail closed, country-extension domains no longer slip
through the filename exception, and correction term-joining never
merges across a negation.

validation only checks their occurrence counts and does not grant the trusted
near-spelling or split-name matching used for dictionary names. Preserve the
existing descriptions of capture, Parakeet behavior, Proofread with Qwen, and
history.

Review comments at @Sources/Inlay/Views/HistoryPage.swift:
- Line 246: Update the DisclosureGroup title in the screen-hints view to use
“term” when terms.count equals 1 and “terms” otherwise, preserving the existing
count and title format.

P2 Screen ranking blocks the app

ScreenContext.terms runs ranking and spell checks synchronously on MainActor. On a dense window, thousands of checks can freeze the controls and delay finishing a take. The timeout in value(waitingAtMost:) also needs MainActor, so it cannot interrupt this work after 500 ms.

Split ranking into small batches that yield and check the deadline.

**Screen ranking blocks the app**

`ScreenContext.terms` runs ranking and spell checks synchronously on `MainActor`. On a dense window, thousands of checks can freeze the controls and delay finishing a take. The timeout in `value(waitingAtMost:)` also needs `MainActor`, so it cannot interrupt this work after 500 ms.

Split ranking into small batches that yield and check the deadline.

Review triage for the Qwen-live update (22986ff + 485bc47):

Fixed

  • CodeRabbit: docs now state screen hints get weaker rewrite-validation trust than dictionary names (the previous sentence was stale); History disclosure pluralizes "1 term".

Intentionally skipped

  • Greptile P2 "Qualified identifiers lose hints" (os.Logger, config.Load): intentional, as in earlier rounds — lowercase member access is indistinguishable from domains (portal.Travel), and the filter fails closed toward privacy. Hint recall loss is accepted.
  • Greptile P2 "Screen ranking blocks the app": ranking and spell-check stay on the main actor deliberately. NSSpellChecker isn't documented thread-safe (its background API is async requestChecking, which doesn't fit the synchronous ranked loop), work is bounded (3,000 tokens, 1,000-check coverage budget that fails closed), and dense real header windows measured ≤0.4s returning the full 40 hints. Worth revisiting if a desktop take shows UI stalls.

All checks pass on 485bc47. Server path verified live with real Parakeet + Qwen models (see PR description); a desktop take in Inlay Dev with the recommissioned capture is still outstanding.
