ADRs (4)

1. 0005-host-corelib-no-opt-out Host projects cannot opt out of corelib Accepted

   Parser rejects noCorelib and useCorelib false.

   Context

   Every host compilation must see the standard library graph.

   Decision

   Rule	Detail
   Forbidden keys	noCorelib, useCorelib: false rejected at parse
   Templates	Scaffolds must not emit opt-out keys

   Consequences

   Implicit injection in resolve_dependencies always attaches corelib.

   Verification anchors

   projects/parser.rs; template manifest tests.

2. 0006-workspace-shard-cycle-guard Workspace shard cycle guard Accepted

   Corelib member packages must not implicit-back-link to aggregate.

   Context

   Shards under packages/* would create cycles if they gained implicit host edges.

   Decision

   Rule	Detail
   Guard	is_corelib_workspace_shard_manifest skips implicit back-edge
   Host	Only application hosts receive implicit corelib

   Consequences

   Building packages/runtime alone does not pull beskid_corelib as a hidden parent.

   Verification anchors

   resolver.rs; corelib workspace compile tests.

3. 0007-mod-projects-exempt Mod projects exempt from host injection Accepted

   Compiler mods compile as carriers without host corelib rules.

   Context

   Mods are not end-user hosts; injecting corelib would distort mod graphs.

   Decision

   Rule	Detail
   Mod	Does not receive implicit host injection
   Host	Receives implicit corelib per D-CORE-COMP-0005

   Consequences

   Mod SDK projects declare their own dependency closure.

   Verification anchors

   Mod project tests in beskid_tests.

4. 0008-cli-lsp-resolver-parity CLI and LSP resolver parity Accepted

   CLI and LSP share corelib discovery and graph options.

   Context

   IDE analysis must match CLI compilation attachment.

   Decision

   Rule	Detail
   CLI	ensure_corelib_ready before commands
   LSP	CompilationContext::try_for_analysis_path_with_graph_options

   Consequences

   Diagnostic drift between CLI and LSP indicates a resolver bug.

   Verification anchors

   LSP workspace tests; corelib/compile.rs.

• Feature
  Corelib injection and resolution

  Parent feature hub

Superrepo host app (implicit corelib)

A minimal Project.proj with only app dependencies still resolves standard prelude types (including Option types), strings, and fibers because resolve_dependencies attaches beskid_corelib without an explicit Std block.

Explicit corelib path override

dependency {
  name = Std
  source = path
  path = "../../compiler/corelib/beskid_corelib"
}

Used in compiler dogfood projects; must point at aggregate Project.proj.

CI environment

export BESKID_CORELIB_ROOT=/path/to/compiler/corelib
beskid build --project apps/demo/Project.proj

Ensures consistent corelib root when not using bundled install artifacts.

Rejected manifest (parse error)

project {
  name = bad
  noCorelib = true
}

Fails structural validation in reject_corelib_opt_out_keys.
