fix(config): drop only the invalid routing profile, not the whole config - #1819
Conversation
A single `routingProfiles` candidate naming a disabled provider failed the document-level parse, so the loader fell back to the built-in default. The operator's eleven providers, every API key and the entire `modelCosts` table disappeared while the proxy carried on serving and reporting healthy — the only visible symptom being a `404 unknown_profile` from a dry-run, which reads like a broken profile rather than a discarded config. `routingProfileIssues()` and `comboConfigIssues()` are both evaluated per entry but reported through `ctx.addIssue` in the schema's `superRefine`, which makes every entry-level finding a document-level failure. The merge-defaults retry cannot help: the offending entry is still there. So when a parse failure is confined to those two sections, drop exactly the entries it blamed and re-parse. Everything outside them survives. If any issue falls outside — or names the container rather than an entry — nothing is salvaged and the existing backup-and-defaults path runs unchanged. The whole entry goes rather than the individual candidate. A profile that quietly loses one candidate still routes, just not where it was told to, and a policy that silently changed shape is worse than one that is plainly absent. Absent is also the loud option: a dry-run against it answers `unknown_profile`, which together with the new warning points at the real mistake. This follows the salvage rule already established for `apiKeys` in this schema — "a key the user still has deployed must not be collateral damage for one bad neighbour". Validation is unchanged; only the blast radius is. The warning names the dropped entries, the offending provider and the reason, and no `config.json.invalid-*` backup is written, since nothing was discarded — the reporter had accumulated ten of those before noticing.

Apply selective salvage in configDiagnosticsFromRaw.
loadConfig now preserves a salvaged config. configDiagnosticsFromRaw at Lines 2461-2482 still returns { config: getDefaultConfig(), source: "fallback" } after the same merged parse fails.
The existing comment at Lines 2464-2466 confirms that this result can cause a config command to persist defaults over configured providers and keys. Reuse dropInvalidConfigSections after the retry parse in configDiagnosticsFromRaw. Add a regression test that verifies diagnostics retain providers after dropping an invalid routing profile or combo.

Repeat salvage when sections have dependencies.
A routing profile validates against combos at Lines 1633-1638. If an invalid combo is removed in this pass, a profile that references that combo can fail only during salvagedResult. The current code then falls back to defaults and discards valid providers, keys, and costs.
Continue salvage-and-revalidate until validation succeeds, an issue is outside a salvageable named entry, or no entry was removed. Accumulate dropped entries and their issues for the warning. Add a regression test with an invalid combo and a routing profile that references it.

Redact entry IDs before logging the repair warning.
dropped contains raw routing-profile and combo IDs. issue.path.join(".") also serializes raw IDs. These IDs are operator-controlled and can be token-shaped. The warning writes them to console.error.
Redact each dynamic path component with redactSecretString before constructing dropped and reasons. Preserve non-sensitive section names and validation messages.
As per path instructions: “tokens and OAuth material must never be logged or serialized into responses.”

Source: Path instructions
…try ids Four blockers from review, all reproduced against this branch: 1. configDiagnosticsFromRaw still returned getDefaultConfig() with source "fallback". loadConfig salvaged, diagnostics did not, and its own comment says that result can be persisted over the operator's providers and keys. It now runs the same salvage. The validated config comes from the merged candidate while the second argument stays the RAW document minus the same dropped entries, so an absent optional setting is still distinguishable from an injected default. 2. Salvage was one-pass. The sections are not independent of each other, so dropping an invalid combo can expose a profile that referenced it; the second parse failure then discarded the whole config. Salvage now repeats until the document parses, bounded by the number of salvageable entries, and stops as soon as a pass removes nothing. 3. Entry ids are operator-chosen and can be pasted secrets, and both the dropped list and the serialized issue paths went to console.error raw. Dynamic components now go through redactSecretString; static section names stay readable because they are the part that tells the operator where to look. 4. No regression proved the fallback does not weaken the management auth boundary. Added one: on a salvaged config, /api/config still returns 401 anonymously, 401 for the data-plane token, 401 for a wrong admin token, and 200 for the valid admin token, with the salvaged providers intact. Also found while testing: salvage must refuse Codex account namespace collisions. That finding is a relationship between a combo and an account selector but is reported on the combo, so dropping the combo made the document parse and quietly admitted the selector the schema had just refused. Those issues are now unsalvageable and fail the whole document, which is what the two existing namespace-collision tests were asserting.
… the error Follow-up to the previous commit. The first attempt made configDiagnosticsFromRaw return source "file" with error null after a successful salvage, which broke two persisted-combo tests -- correctly. Diagnostics is the surface that TELLS callers the file is invalid, and provider reload, catalog sync, cost reconcile and codex admission all gate on exactly source !== "file" || error !== null. Salvaging the error away would have quietly admitted configs those paths must refuse. The real lidge-jun#1785 defect is narrower: the config PAYLOAD was getDefaultConfig(), so a caller that writes diagnostics back persists factory defaults over the operator's providers, keys and prices. Now source stays "fallback" and error keeps the real schema message, and only the payload changes -- it carries the salvaged document instead of defaults. Full suite on the previous head caught this; the two combo tests are restored to passing without weakening what they assert.

What happens today
One
routingProfilescandidate naming a disabled provider fails the parse at document level, soloadConfigfalls back to the built-in default. Everything else goes with it — providers, API keys,modelCosts, and the profiles that were fine.Reproduced as a test before touching anything (three good providers, prices, and two profiles, one of which names a disabled provider):
That matches the report exactly: 11 providers on disk, 1 served, while
/healthzand the management API stay green throughout.Why it reaches that far
routingProfileIssues()andcomboConfigIssues()are evaluated per entry, but they report throughctx.addIssueinside the schema'ssuperRefine— so an entry-level finding becomes a document-level failure. The merge-defaults retry above can't help either, because the offending entry is still present in the merged object.The change
When a parse failure is confined to
routingProfiles/combos, drop exactly the entries it named and re-parse. After the fix, same fixture:Validation is unchanged — only the blast radius is. A candidate pointing at a disabled provider is still an error and still reported, now naming the profile, the provider and the reason.
Three deliberate choices:
The whole entry is dropped, not the individual candidate. A profile that quietly loses one candidate still routes, just not where the operator told it to; a policy that silently changed shape is a worse outcome than one that is plainly absent. Absent is also the loud option — a dry-run against it answers
unknown_profile, which together with the warning points at the real mistake instead of looking like an unrelated one.Anything outside those two sections salvages nothing. If any issue falls elsewhere, or names the container rather than an entry (
routingProfilesas an array), the existing backup-and-defaults path runs exactly as before. This shouldn't become a way to load configs the loader can't reason about.No
config.json.invalid-*backup is written when salvaging, because nothing was discarded. The reporter had accumulated ten of those before noticing anything was wrong, so the backup staying meaningful is worth preserving.This follows the rule already written into this schema for
apiKeys— "a key the user still has deployed must not be collateral damage for one bad neighbour". Same reasoning, applied one level up.Tests
Six new cases in
tests/config.test.ts:modelCostsand the good profile survive; warning names profile + reasoninvalid-*backup piles upI checked these fail without the fix rather than assuming: with the salvage block removed, the four behavioural tests fail and the two negative controls still pass, which is what they're there for.
Gates
One note on the suite: an earlier run showed 7 failures that did not recur on a clean re-run and were unrelated to this area (image/replay tests). Flagging it rather than quietly reporting only the green run.
