-# Selected terminal sharing — implementation WIP
-
-Base: ThemePack `f868221b5f11810802f929369ac8eee46166079a`.
-Branch: `feat/plugin-terminal-sharing`. This is saved unfinished source, not an
-accepted API or an installable/native-tested workflow. Do not merge or release.
-
-Implemented source so far:
-
-- Canonical optional action-only `terminal.selection.read`, feature
-  `terminal.selection-sharing`, bounded result and host-target schemas; SDK
-  `context.terminals.shareSelection()` and runtime forwarding through the
-  existing `ui.interact` broker. No independent parallel RPC stack.
-- Main-only worker/session generation and window-owner binding accessor; no
-  endpoint or Host DTO returned to plugins.
-- Host target/handle authority, opaque signed short-lived receipts, capacity,
-  expiry and lifecycle hooks; no selected text stored in the authority.
-- Broker admission binding to the selected resource before a once-only grant,
-  signed Preview/Share phases, fixed audit metadata and teardown integration.
-- Trusted app-only selected-target setter, not a plugin API. No database,
-  installation/source/cache identity or private-storage schema changes.
-
-Still missing, and required before this counts as working:
-
-1. Trusted renderer target publication for the real active terminal/workspace;
-   actual bounded selection reader registered by the terminal surface. Read
-   only on Preview, from a visible connected terminal, never through Agent/MCP
-   history/context readers; refuse sensitive input, empty or oversized selection.
-2. Host dialog Preview response and explicit Share rendering, failure states,
-   exact resource/selection consistency and global lifecycle verification.
-3. Canonical/SDK/broker/authority/real-worker/renderer normal and boundary tests,
-   generated-contract and compatibility review (including optional-only
-   declaration semantics), quotas, owner/reconnect/close/revoke/late-result cases.
-4. Useful ordinary-browser synthetic example, fixture ID/hash/precise permissions,
-   build/CI, independent review/fix/review and parent-owned native acceptance.
-5. Separate input-draft layer: reuse the actual compose control without inheriting
-   broadcast targets, overwriting an existing draft silently, writing PTY bytes
-   or sending Enter. Require a separately approved target-bound draft action and
-   final active identity check. No input-proposal method/permission is delivered
-   by this WIP.
-
-Known integration constraints:
-
-- The market source-binding task owns installation, cache, authorization/private
-  storage identity and associated database schema. Coordinate before touching
-  those locations; runtime/assertActive identity must remain host-owned.
-- Keep the ThemePack security-color delta in its own branch/head. Incorporate
-  the eventually accepted head with a normal integration merge, not by rewriting
-  frozen evidence.
-- The user allows simplification of unreleased plugin historical data/protocols;
-  do not add legacy migration layers. Do not remove unrelated host/input data
-  migrations or weaken the sandbox.

@@ -133,3 +133,27 @@ This is source identity and a source-based ordering diagnosis, not a claim that
 baseline runtime failure was reproduced locally. The updated test needs the new
 exact-head CI result. That same first run passed the added Vite browser-import
 smoke, resolving the earlier local temp-directory limitation for that head.
+
+### Native security-color delta
+
+Parent native acceptance at f868 verified zero-permission installation/enabling,
+light/dark Preview and Cancel, Apply across main/Settings windows, Restore
+default, restart persistence, and Disable fallback with the unavailable notice.
+The isolated schema-3 profile was not touched. These core results remain valid.
+
+Native QA also found Forest-colored inner New Host cards/inputs/Save and some
+grant-panel text inside an otherwise fixed security container. The cause was
+Tailwind's derived `--color-*` aliases: changing only raw semantic tokens at the
+boundary does not recompute aliases already resolved on an ancestor. The same
+existing security rule now fixes both raw tokens and those color aliases. The
+selector and protected regions are unchanged; ordinary application cards remain
+theme-controlled. No host, credential or grant operation changed.
+
+The regression renders the actual HostDetailsPanel (including General, Address,
+Credentials cards, real Inputs and Save), plus the real grant-panel root. It
+compiles the production Tailwind source, verifies which aliases those utilities
+consume, checks the fixed declarations, and verifies an ordinary card is outside
+the security selector. This is component/compiled-CSS coverage, not a claim of
+native computed-color acceptance. The parent's native color delta remains the
+final visual check. A local Chromium probe aborted because its SUID sandbox was
+not configured; sandboxing was not disabled to retry.
