dsh-base indexes sessions into `:memory:` with `openAt: never`, so the sidebar matched session titles and workspace names and nothing that was actually said. A durable file behind `first-search` makes the history searchable while a user who never searches never loads SQLite or opens a handle. The cost is a privacy one and it is stated in the overlay: the FTS5 table is not contentless, so message text — including tool-call arguments and tool results — now lives on disk at rest, where before it only lived in the session log. The file is owner-only and never shrinks; deleting a session removes its rows without reclaiming the pages. The overlay gains its first `!!js` row, which the plain js-yaml default schema rejects, so the two tests that parse that file move to a shared reader carrying the same `!!js` dialect `dsh-app-boot` parses it with.
Nothing in the composition told the model what time it is, so it could not date "the latest release" or read "next Tuesday" in the user's own zone — which is what a desktop user asking about current events expects it to do. The refresh interval keeps a long session from carrying one reading per step while still letting a turn that spans it get a fresh one. The new test covers the class of failure this row belongs to rather than the row itself: a bare package name in the overlay is resolved by the harness at boot, so a name that is not installed takes the whole app down with `Cannot find package` and nothing before runtime says so.
The model could search the web but never open a result, so it answered from titles and snippets — the first gap a desktop user hits. Two halves are needed. `dsh-web-app` disables the dsh-base `tool-web` row outright because the agent presets each mount their own scoped one, so re-enabling it here puts `web_fetch` in the global tool layer, which every agent inherits regardless of which preset it composed from. `search` stays off: each preset's own `tool-web` already provides `web_search` and shadows this row for that name. The other half is `dsh-web-fetch-http`, which dsh-base mounts nowhere, so without it the tool exists and every call answers `no usable web provider is registered`. That provider does not guard against SSRF — the model chooses the request target and private addresses are not blocked. This is a deliberate choice and the overlay states it: a literal-IP denylist cannot be complete without resolving DNS first, and network reachability is the runtime's or the sandbox's policy to set, not a decision a content adapter should make, where it would also break a user behind a VPN or a proxied network. Verified in a real app under the stock `standard` preset: `web_fetch` returned example.com, and `web_search` was still present alongside it.

Suggested priority: P2 (includes user-path files (packages/desktop-electron/resources/dsh/home/product.cordis.patch.yml, packages/desktop-electron/src/main/dsh-product-home.test.ts, packages/desktop-electron/src/main/dsh-product-mounts.test.ts, packages/desktop-electron/src/main/dsh-product-patch.testing.ts, packages/desktop-electron/src/main/dsh-session-search.test.ts, packages/desktop-electron/src/main/dsh-web-fetch.test.ts, packages/desktop-electron/src/main/dsh-web-search-plugin.test.ts)).
P1/P0 are reserved for maintainer confirmation. Please relabel manually if this is a release blocker, security issue, data-loss risk, or updater/runtime failure.
The web_fetch comment cited upstream's SSRF warning without saying the product had decided anything about it, so a reader could not tell whether the risk was overlooked or accepted. It now states both upstream prohibitions, the ground for accepting them, the concrete exposure, and where a mitigation would belong. The session search comment claimed deleting a session clears its rows. It does not: rows go during the next search's reconciliation, and with no secure_delete and no VACUUM the freed pages keep the text. The first-search backfill cost and its revision-churn failure were also unstated. The two insert comments sat above the wrong rows.
Nothing read the time-context row, so deleting it, misspelling its id, or dropping refreshIntervalMs all survived — and the last of those is silent, because upstream has no default and the clock then injects on every step. Inserted ids had no coverage either, so a duplicate or a typo composed without complaint. Session search asserted its config without first asserting the row exists, which answers every "is not" the same way an applied row does, and left openAt unchecked against the enum the engine throws on.

- Around line 77-81: Update the tool-web web_fetch configuration to restore an
approval boundary: allow automatic fetching only for URLs returned by web_search
during the current turn, and require explicit user approval for all other URLs,
including private, loopback, and link-local destinations.
- Around line 101-104: Update the session deletion flow associated with the
session-query-sqlite index to remove all indexed message, tool-argument, and
tool-result rows immediately, then apply the documented secure-compaction policy
so deleted SQLite content is not recoverable from database remnants. Add
coverage verifying both FTS query results and on-disk database remnants after
deletion.

…laim The `web` row named its search provider but left the fetch side to the seam's sole-provider fallback, so mounting a second fetch provider would have made every web_fetch fail as ambiguous. It now names `http`, pinned in a test against the constant the provider registers under. Three comment claims were wrong or missing. `web_fetch` was described as lacking an approval gate that `bash` has; `bash`'s gate covers only sandbox_permissions escalation, so neither tool is gated on egress and the acceptance argument is stronger than it read. `openAt` was described as choosing when to pay for the backfill; it governs only when the file is opened — the backfill lands on the first search either way, is all-or- nothing, and restarts whenever the sidebar aborts on a keystroke. And `refreshIntervalMs` is also the noise knob for the session index, because each injection is a real user/message the indexer cannot tell apart. Also cut the parts a future writer would not act on: the motive narratives, the framing sentences, and a threat-model note about an upstream package that would go stale here without anyone noticing.

Stacked on #1606 — review that one first; this branch contains its commit.
Three capabilities the harness ships but the default composition leaves off. Each is one row of the product overlay, and each is its own commit.
web_fetch(1deb6cc)The model could search the web but never open a result, so it answered from titles and snippets.
Two halves are needed.
dsh-web-appdisables the dsh-basetool-webrow outright because the agent presets each mount their own scoped one — so re-enabling it here putsweb_fetchin the global tool layer, which every agent inherits regardless of which preset it composed from (dsh-toolsview(scope)seedsinheritedfromlayers.global).searchstays off: each preset's owntool-webalready providesweb_searchand shadows this row for that name. The other half isdsh-web-fetch-http, which dsh-base mounts nowhere — without it the tool exists and every call answersno usable web provider is registered.That provider does not guard against SSRF: the model chooses the request target and private addresses are not blocked. This is deliberate and the overlay says so. A literal-IP denylist cannot be complete without resolving DNS first, and network reachability is the runtime's or the sandbox's policy to set — not a decision a content adapter should make, where it would also break a user behind a VPN or a proxied network.
Session full-text search (
0602ff0)dsh-baseindexes into:memory:withopenAt: never, so the sidebar matched session titles and workspace names but nothing that was actually said. A durable file behindopenAt: first-searchmakes the history searchable while a user who never searches never loads SQLite or opens a handle.The cost is a privacy one and it is real. The FTS5 table is not contentless, so message text — including tool-call arguments and tool results — now lives on disk at rest, where before it only lived in the session log. The file is owner-only (0600) and never shrinks: deleting a session removes its rows without reclaiming the pages, and there is no vacuum, no retention window, and no UI to clear it. A ~125MB session history produced a ~23MB index in testing. If that trade is not the one we want, this commit is the one to drop — the other two do not depend on it.
Time (
be3d989)Nothing told the model what time it is, so it could not date "the latest release" or read "next Tuesday" in the user's own zone. The 60s interval keeps a long session from carrying one reading per step while letting a turn that spans it get a fresh one.
What this replaced
An earlier revision of this branch shipped a generated PawWork agent preset that
Included the upstreamstandardcomposition and patched itstool-webrow, rewritten on every launch with an absolute path to the installed harness. That was built on a wrong premise — that host-plane tools do not reach agents. They do. Deleting the mechanism took two P0 defects with it: apathToFileURLhref interpolated into an unescaped single-quoted YAML scalar (any install path containing an apostrophe would have made every session fail to compose, with no fallback), and a nestedIncludeholding a writable pointer into the signed app bundle, outside thewrite()no-op that upstream added toPresetTreefor exactly that reason.Both were found by an adversarial review of the earlier revision, and both are gone rather than fixed.
Tests
The new tests assert the classes of failure these rows belong to, not the rows themselves:
dsh-product-mounts.test.tsresolves every@deepseek-ai/*package the overlay inserts by bare name. That is the failure this branch actually hit during development: a name the harness cannot resolve takes the whole app down at boot withCannot find package, and nothing before runtime says so. Version-literal assertions were considered and rejected — they restatepackage.jsonand go red on every routine bump.dsh-session-search.test.tsasserts the three upstream values the row exists to displace (:memory:,never,startup) rather than reading its own replacements back.dsh-web-fetch.test.tscouples the two halves, since either alone is a broken product and nothing else in the file relates them.dsh-product-patch.testing.tsis a shared reader carrying the!!jsdialectdsh-app-bootparses the overlay with; the overlay gains its first!!jsrow here, which the plain js-yaml default schema rejects.Verification
