Summary

Work package 2a-1 of the mega-file split program (devlog/_plan/260818_megafile_split_program, 030_wp2a_provider_name_leaf.md). Parallel PR off dev — deliberately not stacked on the types stack (#2019/#2023): disjoint files.

Extracts the provider-name primitives from src/config.ts into a zero-import leaf and breaks the long-standing config <-> routing/profile import cycle:

  • src/config/provider-name.ts (new) — RESERVED_PROVIDER_NAMES, PROVIDER_NAME_PATTERN, isValidProviderName, hasOwnProvider. Zero imports; no mutable state (const Set, .has() only; non-global regex).
  • src/config.ts — bodies deleted; top-level local import (the three superRefine call sites at 1150/1390/1597 stay bound) + barrel re-export so all 15+ existing consumers and 2 test files keep importing from ./config.
  • src/routing/profile.ts — retargets hasOwnProvider to the leaf. Profile imported nothing else from config, so the profile -> config edge is gone entirely; config -> profile (routingProfileIssues) is now one-way.
  • src/router.ts — import split: hasOwnProvider from the leaf, resolveEnvValue stays on the barrel.

Audited by two independent reviewers pre-implementation (grok-4.6 PASS, gpt-5.6-sol NEAR-PASS); the one residual (a graph-shrink overclaim in the plan) was corrected in the devlog, not the code.

Verification

At head 7561e55 on the remote validation host (Linux):

  • bun run test: 13,269 pass / 12 fail — all 12 failures are pre-existing on dev: the identical unique fail set reproduces on a clean dev@aaf04690e worktree without this diff (which currently shows 19 fails). Zero new failures from this change.
  • tests/core-lab-boundary.test.ts: 13 pass (router's new leaf edge is walked; dead-end, no lab reach)
  • Focused: tests/config.test.ts + tests/policy-execution.test.ts 168 pass (barrel imports still resolve)
  • bun run typecheck: exit 0

Note for maintainers: dev@aaf04690e is currently red (12 stable + flaky extras: combo-failover matrix x6, app-server sync wiring, restore-back, raw-reasoning parity x2, command-code catalog, local-api auth) — appears to originate from today's merge campaign, independent of this PR.

Checklist

  • Targets dev
  • Full suite run; failures attributed to pre-existing dev breakage with baseline evidence
  • No user-facing behavior change; no docs-site update needed
  • No new logging; privacy surface untouched

Summary by CodeRabbit

  • Bug Fixes

    • Improved provider-name validation for whitespace, formatting, length, and reserved names.
    • Provider lookups now ignore inherited properties, preventing unintended matches.
  • Refactor

    • Reorganized provider configuration handling without changing routing behavior.
    • Existing configuration exports remain available for compatibility.

Review Change Stack

📝 Walkthrough

Walkthrough

The change extracts provider-name validation into src/config/provider-name.ts, preserves re-exports from src/config.ts, and updates routing consumers to import hasOwnProvider directly from the new leaf module.

Changes

Provider Name Leaf

Layer / File(s) Summary
Provider-name module and config exports
devlog/_plan/.../030_wp2a_provider_name_leaf.md, src/config/provider-name.ts, src/config.ts
Adds isValidProviderName and hasOwnProvider to the dedicated module. Removes their local implementations from src/config.ts and re-exports them.
Routing consumer imports
src/router.ts, src/routing/profile.ts
Routes hasOwnProvider imports to config/provider-name while retaining resolveEnvValue from config.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to 7561e

The refactor does not introduce a user-facing behavior change, but the accompanying plan document still contains an inaccurate acceptance statement and formatting that may fail documentation lint. The PR is mergeable with explicit owner awareness or follow-up on those documentation issues.

Split the first two acceptance criteria into separate list items.

Line 35 contains 1. and 2. in one Markdown list item. markdownlint-cli2 therefore reports MD029 on Lines 36, 38, and 41. This can fail documentation lint.

Proposed fix
-1. typecheck exit 0. 2. lidge full suite 0 fail (baseline 13201 pass).

Remove the stale protected-graph claim.

Lines 36-37 say that the protected graph shrinks. Lines 55-57 correctly state that it does not shrink because src/router.ts still imports resolveEnvValue from src/config.ts. Replace this text with the actual acceptance condition: verify that the configrouting/profile cycle is removed.
