A bundle stands on the toolchain it is compiled in (hq issue 211)

A manifest names its toolchain by language, not in build.on, so the planner did not know a bundle depends on the module that publishes its toolchain and built the two in one tier: the bundle against the old toolchain, recorded as built from the new commit. The edge is read from the manifest, so it holds before any build recorded it, and a toolchain that moves rebuilds every bundle compiled in it.

 ## The image

-**The mesh no longer runs the controller from it** (novox/hq issue 213). The module declares a Go
-bundle, `controller`, which the host on the controller's machine unpacks and runs as the process
-`mesh-controller` under the account of the same name (ADR 0188 §1, §3). The image stays for what
-still runs a container of the controller: genesis, which raises the first controller from it and
-installs the module from its manifest (mesh-host `internal/bootstrap`), and the lab. Neither is the
-mesh's own build any more — `make image` builds it.

 manager, no libc, no CA certificates.

-// A module's own packages, installed before its bundle is compiled, so the bundler inlines them.
-//
-// **A bundle could only import what the toolchain happened to carry.** The compiler and the bundler
-// resolve an import by walking up from the module's source: the module's own directory first, then
-// the toolchain image's node_modules. Nothing ever put anything in the first, so a module needing a
-// database driver (`pg`, `mongodb`, `mssql`) could not be a bundle at all, and kept a container whose
-// recipe installed it by hand (novox/hq ADR 0198 §4: "the backend's own driver inside the bundle").
-// Now the module's `package.json` says what it depends on, as any Node package does, and the build
-// installs exactly that into the module's own directory before compiling.
-//
-// **The SDK the toolchain carries is the one a bundle is built with, whatever the module says**
-// (novox/hq issue 212: the toolchain is rebuilt on every SDK release and every bundle after it). A
-// module's `package.json` names `@novox/mesh-sdk` with a range — it has to, to type-check on a
-// workstation — and installing that range would shadow the toolchain's copy for this module alone:
-// one module compiled against an older SDK than its neighbours, chosen by a caret nobody re-reads.
-// So the SDK is taken out of what is installed (and never fetched), and any copy something else
-// pulls in is removed afterwards; every import of it resolves past the module's node_modules to the
-// toolchain's. A module therefore cannot pin a different SDK, by design: the toolchain is the pin.
-//
-// **Correctness before speed.** Every build installs afresh into a fresh clone, from the lockfile
-// when the module has one (`npm ci`, exact) and from its ranges otherwise; nothing installed is kept
-// between builds. What is shared is npm's own download cache, a named volume, which is
-// content-addressed and verified by integrity on every read — it saves the network, never the
-// install. Install scripts do not run: the build node runs nobody's postinstall, and what a script

-// ever removed one. The registry's own answer — collect what no tag names — is wrong here, because
-// the mesh pushes each artifact under one moving tag and pins machines by digest, so every build
-// but the newest is untagged and some machine may still be running it.
-//
-// **So the mesh decides, from its own records, and it never has to look in the store to do it.**
-// It has never put anything there it did not record, which means every digest it could remove is
-// already in a build row. A digest the mesh did not record making is therefore never named here —
-// not as a safety margin but as the rule restated, and it is what keeps the sweep away from the
-// images genesis pushed before any record existed (04-ISSUES/102, F4).
