Conversation
📝 WalkthroughWalkthroughAdds a files-based settings foundation with shared schemas, project and global JSON/JSONC layers, revision checks, atomic writes, locking, history, RPC operations, and live change events. Integration tests cover persistence, concurrency, validation, and cross-session updates. ChangesSettings Foundation
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟠 High · up to The new compound settings operations can write one layer and then fail before the second, leaving project/global values inconsistent and connected clients unaware of the partial change. The mutation contract also allows an omitted value to delete a setting, so the current head is not merge-ready until the compound write failure path and input validation are fixed.

Remove c12 from the dependency list.
The changeset states the change adds a dependency on c12. The PR description states the opposite: c12 is not used for reading, because it does not support the required settings.json JSONC handling and per-layer error isolation. This line becomes an incorrect public release note.

🌐 Web query:
In Zod 4, does z.unknown() inside z.object() make the property optional and accept undefined?
💡 Result:
In Zod 4, the behavior of z.unknown (and z.any) inside a z.object is nuanced, differing between static type inference and runtime validation [1][2]. Static Type Inference: In Zod 4, TypeScript correctly infers these properties as required [3]. Unlike in some previous versions or configurations, z.infer will treat the key as mandatory, and TypeScript will issue an error if the property is missing from an object [3]. Runtime Validation: At runtime, Zod continues to treat properties defined with z.unknown or z.any as optional [2]. If the property is missing from the input object, Zod will not throw a validation error; instead, it will pass undefined as the value for that key [2]. This occurs because Zod's internal parsing logic treats any schema that can accept undefined (which unknown and any do) as optional during execution [1][2]. If you need to enforce that a property is present at runtime, you can use the.nonoptional method on the schema: const schema = z.object({ field: z.unknown.nonoptional }); schema.parse({}); // Throws a validation error [2]

Require value to be present in settings.set and settings.applyGlobally.
At runtime, Zod 4 accepts an omitted z.unknown() property. The resulting undefined skips registry validation. persist then deletes the setting, including the global value in applyGlobally. Use z.unknown().nonoptional() so omitted values cannot trigger deletion.

Align the Node engine requirement before adopting write-file-atomic@8.
write-file-atomic@8.0.0 requires Node ^22.22.2 || ^24.15.0 || >=26.0.0, but the repository declares >=22.13. Update the supported Node range or use a compatible runtime version. Keep @types/write-file-atomic@^4.0.3; version 8 has no bundled declarations, and the synchronous call is valid.

Line 407 cannot fail; use lstatSync and call the method.
Two defects make this assertion vacuous:
statSyncfollows symlinks. It describes the target file, never the link.isSymbolicLinkis a method onStats, not a property.expect(fn).toBeDefined()passes for everyStatsobject.
So the test title promises the write preserves the symlink, but nothing verifies it. Use lstatSync and invoke the method.
💚 Proposed fix
- expect(statSync(projectFile).isSymbolicLink).toBeDefined()
+ expect(lstatSync(projectFile).isSymbolicLink()).toBe(true)Add lstatSync to the node:fs import:
import {
chmodSync,
existsSync,
+ lstatSync,
mkdirSync,
mkdtempSync,
readdirSync,
readFileSync,
statSync,
symlinkSync,
writeFileSync,
} from 'node:fs'📝 Committable suggestion

Layered settings over two layers: the project layer under <stateRoot>/.conciv and the global layer under ~/.conciv, resolved project over global over registry default. Each layer honors settings.jsonc if present, otherwise settings.json. - @conciv/protocol: namespaced settings registry (duplicate namespace or key throws at registration), v1 registers appearance.scheme, plus the wire schemas and SETTINGS_CHANGED_EVENT. - @conciv/core: settings service loading each layer through c12 (pinned to the stable 3.x line), with per-layer content revisions for optimistic concurrency, minimal-diff jsonc-parser writes that preserve formatting and .jsonc comments, atomic persistence through write-file-atomic, a proper-lockfile guard on the shared global file, an append-only history sidecar, and a watcher that dedupes the service's own writes by revision. c12's merged output is unused: per-key and per-layer resolution stays ours so provenance and parse-error isolation are exact. - @conciv/contract + core router: settings group (get, set, clear, applyGlobally, history) wired beside navigation, broadcasting settings-changed through the new SessionStreams.publishAll.

Make cross-layer writes recoverable.
Lines 286-288 commit the first layer before attempting the next layer. If the later writeLayer call fails, applyGlobally or reset leaves a partial settings update. The function then exits before announce, so active sessions can miss the committed partial change.
Use a transaction journal with rollback or another recoverable commit protocol. Update layers and publish the change only after the compound operation completes successfully.

Foundation (part 1, v2) for #572 (widget user settings). No settings panel and no chat-agent settings tool here — those land in later PRs.
This replaces the closed #574. That PR implemented the sqlite design (
settings_logtable,openGlobalDb(),~/.conciv/conciv.db). The design was since amended to layered config files, so the entire storage approach is superseded: no@conciv/dbchanges, no migrations, no global database. Only the contract-group shape and the settings-changed event mechanism carried over as ideas — the code is new.What ships
@conciv/protocol(settings-types.ts) — a namespaced settings registry. A group owns a top-level namespace and registers keys under it; each key carries a zod schema, a default, a label and a description. Registering a duplicate namespace, or a duplicate key inside one namespace, throws at registration time. v1 registers exactlyappearance.scheme(auto | light | dark, defaultauto). Also the wire schemas andSETTINGS_CHANGED_EVENT.@conciv/core(src/settings/) — the service:<stateRoot>/.conciv/, global under~/.conciv/(override for tests viaglobalSettingsDir, following the existingdevEndpointDirprecedent;defaultDevEndpointDirand the settings home now share oneconcivHomeDir()).settings.jsoncis checked first, thensettings.json; exactly one is honored. If both exist in one layer,.jsoncwins and a warning is surfaced on the same channel as parse errors. If neither exists, the first programmatic write createssettings.jsonc..jsoncallows comments and trailing commas, and hand-written comments surviveset,clearandapplyGloballythrough jsonc-parser minimal-diff edits..jsonstays strict JSON — a comment in a.jsonfile is not reinterpreted as JSONC, it is simply a parse error and follows the malformed path. Both are loaded through c12, which already routes by extension (confbox for.jsonc, strict for.json).project ?? global ?? registry default, per key, with invalid distinguished from absent: a stored value that fails the key's schema is reportedinvalid(with the raw value) and resolution continues past it. Unregistered keys in a file are ignored and preserved.expectedRevisionon every mutation. A stale revision is aREVISION_CONFLICT(409), never a silent overwrite.parseError; writes to that layer are refused withLAYER_UNPARSEABLEuntil it parses again. The unparseable file is never touched.modify+applyEditsminimal-diff against current on-disk text, so indentation and key order survive a programmatic edit instead of a full re-serialize. Persisted throughwrite-file-atomic. Immediate, never debounced. Defaults are never written;cleardeletes the key and drops the parent namespace object when it becomes empty.proper-lockfilelock and rereads under it before editing.file. It dedupes the service's own writes by content revision — the write path records the revision it just persisted, so the watcher sees no change and a server write produces exactly one event, never two. No boolean "is writing" latch.settings-audit.jsonlbeside the settings file in each layer, one line per change{ts, actor, scope, key, from, to, opId}. Never read for resolution; corrupt lines are skipped; the global sidecar is written under the same lock.@conciv/contract+ core router — asettingsgroup added the same waynavigationis:get→ one read serving everything: per key the effective value, controlling layer, and each layer's raw value + validity, plus each layer's path, format, revision, parse error and warning.set {key, value, scope, expectedRevision}/clear {key, scope, expectedRevision}— the single-layer primitives.applyGlobally {key, value, expectedRevisions}— one server-side compound op: lock global, validate, check both revisions before writing either, write global, clear the project override, two history lines sharing oneopId, and exactly one settings-changed event. Clients never sequence a set-then-clear themselves.reset {key, expectedRevisions}— the same compound-op shape asapplyGlobally, clearing the key from both layers in one operation instead of writing global and clearing project. Shares the same lock-acquire/re-read/revision-guard/write/history/announce helper asapplyGlobally; a layer with no value for the key is a no-op for that layer (no history row), and the whole op still shares oneopIdand fires exactly one settings-changed event.history {key}→ sidecar entries from both layers, newest first.Actor is hardcoded
'user'at the RPC handler; theagentactor is a later lane. Errors:UNKNOWN_KEY,INVALID_VALUE,REVISION_CONFLICT,LAYER_UNPARSEABLE,LOCK_TIMEOUT.Settings changes are not scoped to one chat session, so
SessionStreamsgainspublishAll(broadcast to every currently-listening session) over the existing SSE stream.Library findings (verified from source and by probe, not assumed)
c12 loads both formats natively, by extension. Its loader maps extensions to parsers (
dist/index.mjs~L91):.jsoncroutes to confboxparseJSONC, while.jsonhas no tolerant-loader entry and goes through jiti's strictJSON.parse. That split is exactly the semantics this design wants, so the dual-extension support needs no wrapper. Probed directly: a.jsoncfile carrying//and/* */comments parses to the right object, and the same content in a.jsonfile throws aSyntaxError. Both behaviors are covered by tests.c12's merged output stays unused, deliberately. Two findings from the same source read and probe:
layerspopulates only fromextends(dist~L248). A plain single-file load returnslayers: [], so it is not a way to load N arbitrary paths as layers. Our project and global files are independent absolute paths, and per-key provenance has to distinguish which layer supplied a value, so resolution stays ours.{}rather than reporting a problem — which would make a corrupted settings file indistinguishable from an empty one and let a write silently clobber it. So parse-error detection is done explicitly with jsonc-parser (strict options for.json, tolerant for.jsonc) before c12 is asked to load, and reads fall back to last-known-good per layer.c12's
watchConfigis not usable here, and this is measured, not assumed. ItswatchingFilesis derived fromconfig.layersand built asconfigFileName + ext. Probed: with the file missing,watchingFilesis[], so chokidar watches nothing and creating the file fires no event; with the file present andconfigFile: 'settings.jsonc', the computed list issettings.jsonc.js,settings.jsonc.ts, …settings.jsonc.jsonc— the actual file is absent from the list, and noonUpdate/onWatchever fired for a real edit. Making it fire would require a file that always exists, which conflicts with "defaults are never written to disk". Watching is thereforenode:fs.watchon each layer directory, filtered to the two settings filenames, wrapped with the debounce and revision-based echo-dedupe described above. c12 is pinned to~3.3.4: a barepnpm add c12resolves4.0.0-beta.5, and the pin cannot cross into 4.x.write-file-atomic@8 realpaths the target first, so it writes through a symlink rather than replacing it — the requirement is met natively. Whenmode/chownare not passed it copies both off the existing file, so passingmodeexplicitly would defeat permission preservation; only{encoding: 'utf8', fsync: true}is passed deliberately. Both behaviors have tests.proper-lockfile@4 defaultsrealpath: true, which requires the target to already exist — the global settings file often does not. The lock is taken on the always-present~/.concivdirectory withrealpath: false, an explicitlockfilePath,stale: 5000,update: 2000, and bounded randomized retries (12, 25ms→500ms) sized for a small file edited by developer-triggered writes.jsonc-parser removes comments that sit inside a deleted property's range (a comment directly above a removed key goes with it, as in VS Code). Comments elsewhere in the file survive; the tests assert exactly that.
