Merge remote-tracking branch 'origin/main' into feat/mail-list

Review round 2 F3 (ADR 0517 §3, 1858/AC5): acted=1 stayed in the address, so a reload, a restored tab or a
bookmark of it recorded no page opened or opened. An act's 303 (and a mode chosen) now sets mail_acted for
10 seconds, HttpOnly and SameSite=Strict, Secure but on 127.0.0.1; the next list or pane it reaches records
nothing and clears it; the address carries no marker. The local run keeps the browser's other cookies.

+#      it could not be type-checked or tested, and what could not run is a failure, never a note (novox/hq
+#      issue 385);
+#   2. every source that is not a test is type-checked with the toolchain's compiler and the flags a build
+#      compiles with — the same check the build makes, before the merge rather than in the walk;
+#   3. its tests (test/*.test.ts) run under Node's own runner with types stripped, as its own `npm test` does
+#      after its build: the sources are compiled to dist/ and beside themselves first, so a test that imports
+#      the compiled module, or a source that imports its sibling by its .js name, finds it.
+#
+# Said, never passed silently: a module with no tests is said NOT TESTED on every run that touches it —

+#
+# The catalogue's own check (novox/hq ADR 0237 as amended): the second layer of a pull request's merge
+# check, `mesh/repo-check`, run by the build seat in the mesh's Go toolchain.
+#
+# The gate — the manifests the change touches through the running controller's module check, every machine
+# of the facts snapshot composed with them and validated by the node-engine's own validator, the replays
+# against this tree — is the build seat's first layer (`mesh/merge-gate`), run because the mesh's module
+# graph builds these modules from here. It is not repeated here. This is the repository's own:
+#
+#   1. every manifest through the controller's module check, so one module's change cannot leave another
+#      it shares a rule with refused (MESH_GATE is the controller the mesh runs) — and the count of
+#      long-running resources without `health` held to the number in health-undeclared, which only goes down;
+#   2. the Go tests of every module the change touches that has them, under the race detector when the
+#      toolchain has a C compiler. A requirement of the mesh's own forge the module cache does not hold (a
+#      pinned SDK commit) is taken from its repository's clone beside the check (checks/deps); a module whose
+#      dependencies still cannot be had **fails the check**, by name and why — its tests could not run, and a
+#      test that could not run is a failure, never a note (novox/hq issue 385). The integration tests (`//go:build
+#      integration`) run here, with -tags integration, and only here. A module written in
+#      TypeScript is type-checked and tested by
+#      merge-check-typescript.sh, declared above, in the TypeScript toolchain (novox/hq issues 302, 311);
+#   3. the words (novox/hq ADR 0244): no word the glossary retired for the tools, as copied in
+#      retired-words, in any text a module's tools can show an agent — every string in its own code that is
+#      not a test, and every description in its manifest. Run over every module, not only the touched ones,
+#      so a word newly retired is found everywhere it stands. The check's own test runs first.
+#   4. the paths (novox/hq ADR 0260): no module names a path under /run, /var/lib, /usr/local/lib or /etc
+#      that another module's manifest places — modules talk over the bus, not through each other's files.
+#      Over every module; checks/paths/shared and checks/paths/known narrow it, and known only shrinks.
+#   5. the agent's home (novox/hq ADR 0266): no module unpacks an archive, or writes into a file, under
+#      ${machine:agent-home} — the node-engine does both after checking the path, and the agent account owns
+#      that home and could swap a link in between.
+#   6. the secrets (novox/hq issue 342): no mergeable file fills a key with a vault secret that a setting could
+#      replace — the key is `protected`, or left out of the file's `takes-settings`. checks/secrets/known names
+#      the nested ones the controller cannot protect alone yet, and only shrinks.
+#   7. the list of predefined keys (novox/hq ADR 0348 clause 7): a change to predefined.json removes no key a
+#      module still names, judged against the trunk's copy at the merge base. Whether a removed key still holds a
+#      value at the mesh or a node is mesh-config's to refuse; this check reads no store. The list itself and
+#      every manifest against it are judged by the controller's module check in step 1.
+#   8. the config form (novox/hq ADR 0348 clauses 1 and 11): no module says `settings`, `takes-settings` or
+#      `${setting:<key>}`, in its manifest or a template it names, or has a mergeable file naming no keys (which
+#      takes its whole layer), unless checks/config/unmoved lists it as not yet moved; that list only shrinks,
+#      judged against the trunk's copy at the merge base.
+#   9. the file text (novox/hq ADR 0349 §2): no module keeps a file's text inline in its manifest (`content`)
+#      unless checks/templates/inline lists it as not yet moved; each names its template in files/. That list
+#      only shrinks, judged against the trunk's copy at the merge base.
+#   10. the mail-store seat (novox/hq ADR 0378 §3, issue 800): no manifest but modules/mesh-mail claims it.
+#   11. owned paths (novox/hq ADR 0422 §8, issue 1024; it holds ~/.ssh for ssh-client as ADR 0415 §6 asked):
+#      every directory and archive says `unknown` (move-out, module or program) and a valid `knows`; `move-out`
+#      only under a home; no module declares a path inside a directory of another module; and none is, lies in or
+#      holds a directory a system package owns under /var/lib (checks/owned/system, issue 1841).
+#      checks/sshdir (ADR 0415 §6) stays while main runs it; it goes under issue 1035 once main runs checks/owned.
+#   12. the image builder (novox/hq ADR 0487 §3, issue 1704): only modules/buildah provides rootless-image-build.
+#   13. the image's place (novox/hq ADR 0487 §1, issue 1707): every image builds from a Dockerfile in its own module's directory.
