chore(deps): drop two dead subsystems, rfd, and memory-git from the shipped app

[senamakel]

Summary

• Delete two subsystems orphaned by Remove the CDP layer and every surface that depends on it #5478: the webview_apis WS bridge (its router dispatched nothing, yet it still bound a loopback listener at boot and aborted app startup if the bind failed) and the whatsapp_data store (its only writer, the CDP whatsapp_scanner, was deleted, so nothing could write it).
• Delete memory-git outright — the feature, the memory::diff RPC surface, the memory_diff agent tool and the memory_artifacts_e2e target. It was the last gate carrying removable native C builds, and git2 is now absent from the resolved graph entirely rather than merely un-enabled.
• Remove rfd and the native Save-As dialog; artifact export keeps the Downloads copy that was already its portal-less fallback.
• Remove three dependencies the shell declares but never references: base64, cpal, uuid (cargo machete is now clean).
• Net: 572 packages / 523 names / 2 native builds, down from 588 / 537 / 4. −6,816 lines.

Problem

An audit of the Tauri shell's dependency graph found that the gating program has already banked the crate savings: measured per-gate sheds in the core product profile are media 0, inference 0, modules 0, skills 0, mcp 0, contacts 0 (Linux), runtime-node 0, and the 167 names the desktop layer adds on top of the core are essentially all tauri/wry/gtk/webkit — not removable. What remained was of two kinds.

Dead code that survived a removal. #5478 deleted the CDP provider scanners when the app moved off Chromium to Wry (#5456), but two things they fed outlived them:

• app/src-tauri/src/webview_apis/ — router.rs's own doc comment says "Currently empty — the only consumer was the Gmail embedded-webview bridge, which has been retired", and dispatch_inner unconditionally returns unknown method. There is no src/openhuman/webview_apis/ counterpart in the core any more, and OPENHUMAN_WEBVIEW_APIS_PORT has no reader anywhere in the tree. It nonetheless started a WebSocket server in setup() and returned Err("webview_apis bridge failed to start — aborting setup") on a bind failure — a dead subsystem that could refuse to start the app.
• whatsapp_data — 2,506 shell lines plus a core domain, 3 agent tools, 3 IPC commands and a UI section, all reading a SQLite store that no code path can write. grep for methods::INGEST across the core, the shell and the frontend returns only the registration itself.

One gate whose value is native builds, not crates. memory-git sheds only 3 crates, but git2 brings libgit2-sys and libz-sys — 2 of the 4 C toolchain builds in the product profile, and the slowest. memory_diff has no frontend caller.

Un-shipping it was not enough. Leaving the gate in place while no lane enabled it left memory::diff's three source files compiled by nothing, which assert-coverage-presence.sh correctly rejected: "Coverage lane produced NO records for 3 changed source file(s) — they were never compiled, so nothing verified them." The escape hatch it offers is coverage-presence-allowlist.txt, but that file is an explicit ratchet — "entries come off, they do not go on" — and its only entry is a structural stub, not real implementation. So the feature is deleted rather than parked.

Solution

• webview_apis: module deleted; the setup() bridge start, both teardown server::stop() calls and the exit-path comment removed from lib.rs.
• whatsapp_data: shell module, core domain (src/openhuman/channels/whatsapp_data/), the three WhatsAppData*Tool registrations, the whatsapp_data_ arm in tool_group, the Tauri commands and their allow-core-process permission entries, WhatsAppMemorySection and its three i18n keys across all 14 locales, the E2E scenario and the json_rpc_e2e test.
  • Removing the tools leaves DomainGroup::Channels owning none, so it joins TOOL_LESS beside Relay — the same move the tinyplace_* removal made. The channel runtime, controllers and inbound dispatch are untouched.
  • WhatsApp messaging is unaffected: channels/providers/whatsapp{,_web}.rs and the whatsapp-web gate are a separate surface from the removed history store.
  • "whatsapp_data" stays on the workspace-internal denylist in security/policy/types.rs, moved down beside redirect_links and codegraph with a comment: an upgraded profile still has the old .db on disk and agent file tools must not read it.
• memory-git: deleted — the feature line, src/openhuman/memory/diff/ (mod, rpc, schemas, stub, types), src/openhuman/memory/tools/diff.rs, tests/memory_artifacts_e2e.rs and its [[test]] block, the controller registration and namespace description, and the entry in direct_engine_refs_tests. Two things were deliberately left alone: Capability::Diff and as_diff() in memory/guard/ and modules/memory.rs carry no memory-git cfg — they are TinyMemory bus-contract surface, and a driver may still advertise the capability; there is simply no RPC surface here behind it. And tinycortex keeps its git-diff / wiki-git features (it owns the only libgit2 code in the stack); this repository just no longer enables them.
  • The both-ways gate tests collapse into removal regressions rather than vanishing: memory_diff_controllers_are_gone_and_memory_survives keeps the load-bearing half of the old pair — removing the git ledger must not remove the memory domain — and memory_diff_tool_is_absent_in_every_build does the same at the tool level.
  • "memory_diff" was dropped from the null-driver absence list, where it would now pass vacuously in a test whose purpose is proving the capability filter does something.
  • The AGENTS.md note claiming memory::diff::types must compile in both builds was stale: it is a pure re-export of tinycortex::memory::diff::types, and its only consumer in this crate was the tool that went with it.
• rfd: save_artifact_via_dialog deleted; saveArtifactViaDialog in artifactDownloadService.ts now delegates to downloadArtifact, which has been its fallback for hosts without an xdg-desktop portal since Artifact UX polish: native save-file dialog + ChatToolCallEvent in-progress wiring #3162. Callers may still branch on 'CANCELLED'; nothing produces it. The name is kept because ArtifactCard calls it and a real destination picker may return.
• Two follow-on fixes the memory-git removal forced, both found by CI:
  • tests/json_rpc_e2e.rs's json_rpc_memory_diff_snapshot_diff_and_read_marker_lifecycle called openhuman.memory_diff_take_snapshot with no gate — it passed only because the product lane used to enable memory-git. Now #[cfg(feature = "memory-git")], as a per-symbol gate rather than a required-features line on the target: json_rpc_e2e is otherwise gate-free and gating the whole file would silently skip its other ~100 tests in every lane. Verified both ways — 102/102 with the gate off, and the test itself runs and passes under --features "<product>,memory-git".
  • scripts/ci/rust-coverage-changed.sh runs every tests/*.rs target explicitly (--test <name>), and cargo only skips a target for unsatisfied required-features when it is selected implicitly — naming one is a hard error (target ... requires the features: memory-git). Every required-features target had until now named a gate inside the product set, so this never fired; memory_artifacts_e2e is the first unsatisfiable one. Added a target_features_satisfied guard at run_integration_target, the single chokepoint both call paths share, parsing required-features from Cargo.toml in awk to keep the script jq/python-free. This restores what the required-features line was written to express and stops the next gate removal breaking the lane the same way.
• Two stale docs corrected because this change touched them: the tauri-shell.md module tree still listed cdp/, the cef_* modules, webview_accounts/, every scanner, meet_* and fake_camera — all gone since Remove the CDP layer and every surface that depends on it #5478/refactor(tauri): replace CEF runtime with upstream Wry #5456 — and the coverage matrix's WhatsApp row plus its feature-ids.json entry.

Measured

	packages	names	native C builds
Shell before	588	537	libgit2-sys, libsqlite3-sys, libz-sys, ring
Shell after	572	523	libsqlite3-sys, ring
Core (product)	—	370 → 367	4 → 2

Names that left: rfd, ashpd, pollster, dlib, downcast-rs, scoped-tls, wayland-{backend,client,protocols,scanner,sys}, git2, libgit2-sys, libz-sys.

Worth recording for the next pass: removing a shell dependency usually sheds nothing. base64, cpal, uuid and tokio-tungstenite are each reached again through openhuman_core, async-imap or engineioxide, and gating imessage_scanner / whatsapp_data would shed nothing either because rusqlite is shared. Those are binary-size and dead-code wins only.

Submission Checklist

If a section does not apply to this change, mark the item as N/A with a one-line reason. Do not delete items.

• Tests added or updated — whatsapp_data_tools_are_gone_in_every_build replaces the present/absent gate pair and pins the removal in both directions of the channels gate; download_rejects_bad_source carries over the failure-path coverage from the deleted dialog test; artifactDownloadService.test.ts asserts the Downloads route and that save_artifact_via_dialog is never invoked again.
• Diff coverage ≥ 80% — the change is 4,872 deletions against 140 insertions, most of them comments and doc prose; the executable additions are the two tests above and a one-line delegation, all exercised. CI remains authoritative.
• Coverage matrix updated — row 10.3.3 WhatsApp Agent Retrieval removed along with its scripts/feature-ids.json id; scripts/check-coverage-matrix.mjs reports 249 rows, 136 catalog IDs, 0 parse errors, 0 missing, 0 duplicates.
• All affected feature IDs from the matrix are listed in the PR description under ## Related.
• No new external network dependencies introduced — this PR only removes dependencies.
• N/A: the removed surfaces appear nowhere in docs/RELEASE-MANUAL-SMOKE.md; artifact export still lands in Downloads and is already covered there.
• N/A: no linked issue — this came out of a dependency-graph audit, not a filed report.

Impact

• Desktop, user-visible. The artifact "Save" action no longer opens a Save-As dialog; it copies to Downloads and offers "Reveal in Finder". The WhatsApp chat-count card leaves the Memory workspace — it rendered null for every install since Remove the CDP layer and every surface that depends on it #5478 anyway, since its store could not be written.
• Agent surface. whatsapp_data_list_chats / _list_messages / _search_messages and memory_diff leave the tool list. openhuman.whatsapp_data_* and openhuman.memory_diff_* become unknown-method.
• Data. No migration. An upgraded profile keeps whatsapp_data/whatsapp_data.db and any git-backed diff ledger on disk, untouched and unreadable by agent file tools.
• Build. Two fewer native C builds in the shipped app (4 → 2). Reverting either loss is a one-line change to scripts/ci/product-features.txt plus the shell's forwarding entry.
• Startup. One failure mode removed: the app can no longer abort setup() because a dead bridge failed to bind a loopback port.

Related

• Closes: N/A — audit-driven cleanup with no filed issue.
• Feature IDs affected: 10.3.3 (WhatsApp Agent Retrieval) — removed from the matrix and the catalog.
• Context: Remove the CDP layer and every surface that depends on it #5478 (CDP scanners removed), refactor(tauri): replace CEF runtime with upstream Wry #5456 (CEF → Wry), Artifact UX polish: native save-file dialog + ChatToolCallEvent in-progress wiring #3162 (the Save-As dialog this reverts), refactor(modules): load TinyJuice outside dependency graph #5541 (the previous binary-size pass).
• Follow-up PR(s)/TODOs: AGENTS.md claims the contacts gate sheds 6 crates on macOS; measured 388 → 386 = 2. Not corrected here to keep this diff to the four changes above.

• pnpm typecheck — clean.
• Focused tests: cargo test --test json_rpc_e2e passes 102/102 with the product feature set, and the one memory-git-dependent test in it passes when that gate is turned back on (--features "<product>,memory-git"), confirming it is gated rather than retired; 288 core unit tests across tools::ops_tests / core::all / core::legacy_aliases / security::policy pass; 12 shell artifact_commands tests pass; 48 frontend tests across memory.test.ts, artifactDownloadService.test.ts, MemoryWorkspace.test.tsx pass.
• Rust fmt/check (if changed): cargo check --all-targets green on all three profiles — contributor default, product (scripts/ci/product-features.sh), and the kernel profile (--no-default-features --features flows). scripts/check-kernel-floor.sh reports every profile within its ratchet.

Behavior Changes

• Intended behavior change: remove two subsystems that no code path could reach, drop the memory_diff family and the native Save-As dialog from the shipped product.
• User-visible effect: artifact Save goes straight to Downloads; the WhatsApp memory card and the whatsapp_data_* / memory_diff agent tools are gone. No data is deleted or migrated.

Parity Contract

• Legacy behavior preserved: saveArtifactViaDialog keeps its name, signature and outcome shape, resolving to the Downloads path its own catch block already used. download_artifact_to_downloads keeps its full source-validation and filename-sanitization boundary. Existing on-disk whatsapp_data and git-ledger state is left in place and stays on the agent denylist.
• Guard/fallback/dispatch parity checks: scripts/ci/check-feature-forwarding.mjs passes with 17 gates, set-equal in both directions; check-coverage-matrix.mjs passes; check-kernel-floor.sh passes; whatsapp_data_tools_are_gone_in_every_build and the save_artifact_via_dialog-never-invoked assertion guard against silent reintroduction.
