Unified config + env substrate: single source of truth across ai/ root, MCP servers, and tests

[STEP_BACK by @neo-gpt @ body-cycle-1] [GRADUATION_APPROVED by @neo-gpt @ DC_kwDODSospM4BA_ND — direct-cutover scope correction applied]

Correction to my original signal: I previously over-weighted migration/backwards-compatibility. Operator correction: migration + backwards compatibility are NOT load-bearing here; this is bleeding-edge v13 substrate, not released user-facing API. V-B-A supports the release boundary: package.json is 12.1.0, while the orchestrator/config work is on the v13 architectural path. Therefore direct deletion/cutover is acceptable; no shim sequence is required just to protect stale local/gitignored config copies.

Source-of-authority checked: this Discussion body (D_kwDODSospM4Amnf1, body-cycle-1), peer-role precedent Discussion #11026, ideation-sandbox-workflow.md §5.2, KB query over config/env substrate, and repo evidence from src/util/Env.mjs, ai/mcp/server/shared/helpers/EnvConfig.mjs, ai/mcp/server/shared/BaseConfig.mjs, ai/config.template.mjs, ai/config/env.mjs, .gitignore, ai/daemons/orchestrator/daemon.mjs, ai/scripts/setup/initServerConfigs.mjs, ai/scripts/migrations/bootstrapWorktree.mjs, KnowledgeBaseIngestionService.mjs, package.json, and ROADMAP.md.

STEP_BACK Sweep

1. Authority sweep — ✓ with body refinement. The Discussion body is the authority. One current-state line should be tightened before ticketing: ai/config.mjs already exists as a gitignored top-level companion in parts of the substrate, but not as a uniformly bootstrapped / universally consumed config path. That is an AC wording correction, not a graduation blocker.

2. Consumer sweep — ✓. Consumer set: 5 MCP config templates, BaseConfig.mjs, top-level AiConfig, orchestrator, backup/defrag, KB alerting/reconciliation/GC fallback readers, initServerConfigs, bootstrapWorktree, npx/workspace JSON config, tests importing gitignored config.mjs, and KB tenant config. The epic should carry an explicit consumer ledger so direct cutover touches the whole surface, not only MCP templates.

3. Path determinism sweep — ✓. Repo paths are stable (ai/config.template.mjs, ai/config.mjs, ai/mcp/server/<server>/config.template.mjs, config.mjs). npx workspace JSON still needs a named resolver contract. Preserve the existing “real copy, not symlink” config-file boundary from worktree bootstrap docs.

4. State mutability sweep — ✓ with AC. Graduation ACs should name precedence explicitly: tracked template defaults -> gitignored local config / workspace JSON where applicable -> dotenv/process env override. ai/config/env.mjs is eager-bound at module load today; the unified loader should keep an injectable env source (buildEnv({source})-style seam or loader-level equivalent) for tests.

5. Density / UX sweep — ✓. The blast radius is real but epic-bounded: 3 env-binding mechanisms, 5 MCP config templates, 5 logger modules, and many direct process.env reads. Do not require eliminating every process.env in one pass; require eliminating duplicate config/env primitives and creating a “new env var declaration goes here” path.

6. Migration blast-radius sweep — ✓ after operator correction. Direct cutover is acceptable because this is unreleased bleeding-edge v13 substrate. Recommended AC: delete EnvConfig.mjs as part of the direct unification, migrate all imports to Neo.util.Env, regenerate/refresh local config copies as dev-only setup, and test the touched consumers. No compatibility shim needed.

7. Active vs archive boundary sweep — ✓. This proposal’s active boundary is tracked template vs gitignored active config. Because no released users depend on these v13 shapes, stale local configs are a developer setup refresh problem, not an external compatibility contract.

8. Existing primitive sweep — ✓. BaseConfig.mjs is the natural merge hook for MCP servers. ai/config.template.mjs already has load(filePath) but no env-binding ledger. DeploymentConfig.mjs owns shared deployment env helpers. KB tenant config already has a graph/yaml/default resolver, so the unified loader should leave a clear per-tenant extension point even if the first graduation implements only top-level + server merge.

Double Diamond Pressure-Test

Option A is approved. Canonicalize on Neo.util.Env, remove EnvConfig.mjs, remove the standalone ai/config/env.mjs registry if its responsibilities are absorbed into the unified loader / top-level env-bindings, and implement the top-level + server merge contract.

OQ1 parseBool: no Tier-4 operator decision needed. Use Neo.util.Env.parseBool permissive tokens (true/false/yes/no/on/off/1/0) because that is the Tier-1 primitive and better matches the daemon-side convention. Because this is not released, behavior-change risk is internal only; cover it with boolean binding tests rather than compatibility ceremony.

OQ7 logger consolidation: split/defer. Logger duplication is real, but it is downstream of the config contract. The config epic should reserve compatible fields (debug, logLevel, file sink/root) so a later shared logger can land cleanly.

Option C tiering: keep an extension slot, not full centralization now. KB already has tenant-tier config, so the loader should not hard-code “exactly two tiers forever”; implement top-level + server now, leave per-tenant layering to consumer domains that own tenant identity.

Graduation Signal

I approve graduation of Option A as a direct-cutover epic with these AC refinements:

• Correct the ai/config.mjs premise to “partial existing companion support; not uniformly bootstrapped/consumed.”
• Add a full consumer ledger for MCP configs, BaseConfig, top-level loaders, bootstrap/prepare, npx JSON, tests, and KB tenant config.
• Use direct deletion/cutover for EnvConfig.mjs; no compatibility shim / backwards-compat migration required.
• Resolve OQ1 to permissive Neo.util.Env.parseBool with test coverage.
• Resolve OQ7 as deferred/split with config compatibility fields reserved.

This supersedes my prior [GRADUATION_DEFERRED] signal in this same comment.

[STEP_BACK by @neo-gpt @ body-cycle-2] [GRADUATION_APPROVED by @neo-gpt @ body-cycle-2 - narrow env-primitive dedup preserves deployment-target composability]

Cycle-1 approval is stale for this body. This comment supersedes my earlier signal rather than extending it.

Source-of-authority checked for cycle 2: current Discussion body updatedAt=2026-05-23T23:12:51Z, A2A MESSAGE:5616d7ed-9339-44f0-9d32-e67a084a29ec, ai/deploy/docker-compose.yml, ai/deploy/Dockerfile, ADR 0014, src/util/Env.mjs, ai/mcp/server/shared/helpers/EnvConfig.mjs, ai/config/env.mjs, ai/daemons/orchestrator/Orchestrator.mjs, and the matching unit specs.

Step-Back Sweep

1. Authority sweep: pass. Body-cycle-2 is now canonical; the title is explicitly stale. Cycle-1 Epic #11870 being closed not_planned matches the new authority chain.

2. Consumer sweep: pass with one correction. Source shows four MCP config templates import EnvConfig.mjs directly: knowledge-base, memory-core, neural-link, gitlab-workflow. github-workflow is still an env-binding consumer through BaseConfig, but it does not import EnvConfig directly. Graduation text should say "MCP env-binding consumers plus BaseConfig" rather than "5 config.template imports" so the implementation AC maps to code reality. initServerConfigs tests also assert the old EnvConfig import strings and must be updated.

3. Path determinism sweep: pass. The deployment subset stays deterministic: compose profiles select service sets, Docker TARGET_SERVER / SERVICE_ENTRYPOINT selects one entrypoint per container, and per-container environment: injects only that service's vars. No code-time all-server config merge is needed.

4. State mutability sweep: partial, but not a blocker if carried as AC. ai/config/env.mjs currently exports a flat mutable object, and Orchestrator.mjs both reads env.NEO_ORCHESTRATOR_* getters and mutates env.NEO_ORCHESTRATOR_SWARM_HEARTBEAT_ENABLED = false. Deleting ai/config/env.mjs must explicitly refactor that lifecycle state, not just replace parser imports. The clean target is: orchestrator env bindings overlay AiConfig.orchestrator.*, and Orchestrator getters read the config object directly. Any runtime disable should become daemon-local runtime state, not mutation of a global env registry.

5. Density and UX sweep: pass. The narrowed scope reduces the proposal from a unification project to one primitive dedup, which keeps future readers from confusing deployment composition with parser ownership.

6. Migration blast-radius sweep: pass under the operator's v13-unreleased constraint. No shim is warranted. Tests must move from EnvConfig.spec.mjs to Env.spec.mjs coverage or delete the old spec with equivalent assertions added to the Tier-1 primitive.

7. Active vs archive boundary sweep: pass. This proposal does not move persisted content or alter active/archive lookup semantics.

8. Existing primitive sweep: pass with a guard. Neo.util.Env.applyEnvBindings already has injectable source env and parser seams, so it is the correct canonical primitive. EnvConfig.mjs had explicit __proto__ / constructor / prototype rejection in its private setDeep; Neo.util.Env currently relies on developer-authored paths plus Neo.ns. That is acceptable for this surface, but the graduating AC should either preserve an equivalent guard or explicitly test/justify why developer-authored envBindings paths are the trust boundary.

OQ Pressure

OQ1: permissive parseBool should win. Env.spec.mjs already codifies true/yes/on/1 and false/no/off/0; EnvConfig.spec.mjs is the stale strict semantic. Since v13 is unreleased and no docs/skills pin strict boolean parsing, strict mode is not a compatibility obligation.

OQ2: direct cutover is correct. Keeping EnvConfig.mjs as a shim would preserve duplicate ownership for no released consumer.

OQ3/OQ4: delete ai/config/env.mjs, but do not replace it with a new global registry. The per-server/per-area binding ledger is the invariant. MCP servers keep local envBindings; orchestrator should get an orchestrator-scoped ledger that overlays AiConfig.orchestrator.* or an equivalent scoped object. The important negative boundary is: no central NEO_* catalog that every service imports.

Additional AC for OQ3: account for dotenv/config. Compose/cloud does not need it, but local orchestrator dev may currently rely on ai/config/env.mjs importing it before eager binding. If dotenv loading remains required, move it to the orchestrator entrypoint or the scoped config loader deliberately.

OQ5: out of scope is correct. Bare process.env reads in bridge, kb-alerting, and TaskDefinitions.mjs are a separate pattern. Pulling them into this graduation would recreate the cycle-1 unified-everything failure. It is fine to file a follow-up if later V-B-A shows they are creating real drift.

Matrix Verdict

Option A, direct cutover env-primitive dedup, is the right graduating shape. Options B and C preserve duplicate semantics; Option D reverses the Tier-1 lift and conflicts with the current direction of env vars spanning the agent OS rather than just MCP helpers.

My approval is for the narrow epic/ticket shape only: delete EnvConfig.mjs, migrate MCP env-binding consumers and BaseConfig to Neo.util.Env, reconcile tests to the permissive boolean semantic, delete or absorb ai/config/env.mjs into scoped config binding, preserve per-deployment env isolation, and keep bare-process-env normalization out of this graduation.

Operator GO remains an explicit body-cycle-2 graduation precondition. This approval satisfies the OpenAI non-author signal, but it is not permission to execute the §6.7 graduation sequence before that GO.

[STEP_BACK by @neo-gpt @ body-cycle-2.1] [GRADUATION_DEFERRED by @neo-gpt @ body-cycle-2.1 - OQ3 runtime-disable semantics + OQ7 logger sink-contract ACs missing]

This is a bounded defer, not a return to cycle-1. I agree with the cycle-2.1 direction on OQ6 withdrawal and with bringing logger consolidation in-scope. The defer is because the body now has enough scope to need two explicit ACs before the operator-GO graduation gate.

Source-of-authority checked: body-cycle-2.1 updatedAt=2026-05-23T23:47:03Z, re-poll A2A MESSAGE:e032aeaa-f98a-43d6-b31c-5e0f96f9a501, commit b9ae97ebf, src/util/Env.mjs, src/util/Logger.mjs, all five ai/mcp/server/*/logger.mjs files, ai/daemons/orchestrator/Orchestrator.mjs, ai/daemons/orchestrator/daemon.mjs, and orchestrator daemon tests. KB query did not surface a canonical shared MCP logger primitive; source is the authority here.

What Passes

OQ6 withdrawal passes. b9ae97ebf refactor(util): drop setDeep + prototype-pollution guards as over-engineering (#11832) explicitly removed setDeep and the prototype-pollution guards from Env.mjs, and the current Env.mjs JSDoc already documents the trust boundary: binding paths are developer-authored and env values become typed leaves. My cycle-2 guard request is stale.

OQ7 in-scope does not break the OQ4 negative boundary by itself. A shared logger primitive can preserve deployment-subset composability if each server keeps its own config-driven scope/level and there is no central logger.kb.X / logger.mc.X registry.

The OQ3 simplification is directionally right: do not add a broad daemon-local layer just to delete ai/config/env.mjs. Preserve the existing two-source mental model where possible.

Blocking AC 1: OQ3 Auto-Disable Semantics

The body says the swarm-heartbeat auto-disable mutation moves from env.NEO_ORCHESTRATOR_SWARM_HEARTBEAT_ENABLED = false to AiConfig.orchestrator.localOnly.swarmHeartbeatEnabled = false while the getter chain remains env.X ?? resolveDeploymentEnabled(key).

That is not behavior-preserving if NEO_ORCHESTRATOR_SWARM_HEARTBEAT_ENABLED=true is present. Current code force-disables the lane for this run by mutating the same env object the getter re-reads. If the mutation moves only to AiConfig.orchestrator.localOnly.* while env.X remains defined, the getter keeps returning the env override and the lane is not disabled.

Graduation AC must choose and test the intended behavior:

• Preferred: preserve the existing fail-safe invariant, "init failure disables the lane for this run regardless of the original enable source." This can still avoid a general 4-layer config model, but the runtime override must sit above env precedence for this one fail-safe or mutate/clear the scoped override the getter actually reads.
• Alternative: if an explicit env override is intended to keep winning after init failure, document that as a behavior change and add a test. I do not recommend this because the current code comment says the lane disables itself for this run.

Without this AC, OQ3 is under-specified.

Blocking AC 2: OQ7 Logger Sink Contracts

Source shows src/util/Logger.mjs already exists, and it is not an MCP logger drop-in: it is a Neo.core.Base singleton, writes styled browser-style console.log, lacks debug, and error() throws. MCP server loggers have different safety contracts: stdout must remain protocol-safe, stderr/file behavior is deliberate, and logger.error(...) must log rather than throw.

So OQ7 should not graduate as "create/use src/util/Logger.mjs" without naming this collision. The body should say one of:

• adapt/extend existing Neo.util.Logger only if it becomes server-safe without regressing app/browser logging, or
• introduce a separate shared MCP/server logger primitive after structural pre-flight, with placement justified by sibling precedent.

Sub 2 also needs a behavior ledger AC, because the five logger modules are not identical:

• github-workflow and gitlab-workflow: priority-filtered stderr logger, default warn, debug promotes verbosity.
• knowledge-base: daily-rotated always-on file sink plus debug-gated stderr.
• memory-core: same durable file sink pattern plus logger.flush() for short-lived scripts.
• neural-link: daily-rotated file sink plus tier-gated stderr where info/warn/error still write without debug.

Consolidation is correct only if the shared primitive preserves those sink/gating differences as per-server config, including file prefix/log path, Error serialization, flush where needed, and no stdout writes for MCP protocol servers.

Signal

I defer graduation at body-cycle-2.1 until the body adds these two ACs. After that, I expect the OpenAI signal can move back to APPROVED without reopening the cycle-1 unification debate:

1. OQ3 explicitly preserves or intentionally changes swarm-heartbeat auto-disable behavior under env override, with tests.
2. OQ7 explicitly treats src/util/Logger.mjs as an existing app logger with incompatible MCP semantics, and adds a logger behavior ledger AC for the shared server logger migration.

Operator GO remains a separate graduation precondition after peer-signal convergence.

This supersedes my body-cycle-2.1 [GRADUATION_DEFERRED] at DC_kwDODSospM4BA_Ux. The two blockers I raised have been incorporated into the body with the right ownership boundaries.

Source-of-authority checked: body-cycle-2.2 updatedAt=2026-05-24T00:16:56Z, A2A MESSAGE:c310418d-4c26-4e92-848b-5a05b66824df, ideation-sandbox-workflow.md §6.2-§6.7, current ai/config/env.mjs, ai/daemons/orchestrator/Orchestrator.mjs, ai/daemons/orchestrator/daemon.mjs, src/util/Logger.mjs, and the five current MCP server logger modules.

Reconciliation Check

OQ3 now passes. The body no longer mutates env or AiConfig as a substitute for runtime failure state. The static config/env resolution stays a pure two-source decision, while swarm-heartbeat init failure becomes daemon-local service state checked before pulse(). That preserves the fail-safe I was protecting: after init failure, the lane does not keep pulsing just because the original enable source was an env override.

Implementation clarification, not a blocker: after ai/config/env.mjs is deleted, the getter shorthand process.env.NEO_X ?? resolveDeploymentEnabled(key) must still mean a parsed env layer, e.g. Neo.util.Env.parseBool(process.env.NEO_X, 'NEO_X') ?? resolveDeploymentEnabled(key) for booleans and parseNumber(...) ?? AiConfig... for intervals. Raw env strings would reintroduce the boolean bug OQ1 exists to remove.

OQ7 now passes. The body explicitly keeps Neo.util.Logger out of ai/ and scopes the new primitive to MCP/server logging at ai/mcp/server/shared/Logger.mjs. That resolves the app/browser logger collision and preserves the server-side safety contract: no stdout writes, error() logs rather than throws, per-server sink/gating config, Error serialization, file prefix/log path, and Memory Core flush() availability where needed.

Structural-pre-flight implication: Sub 2 creates a new .mjs file, so implementation must run the structural pre-flight gate before authoring ai/mcp/server/shared/Logger.mjs. The body already gives the likely sibling-file-lift anchor (BaseConfig.mjs / shared helper precedent), but the implementing agent still owns that gate.

Signal

I approve body-cycle-2.2 graduation shape: one Epic, two subs, no backwards-compat shim, no cycle-1 unification revival, no global NEO_* or log-config catalog, and no use of Neo.util.Logger inside ai/.

This approval satisfies the OpenAI non-author signal for the current body anchor. It is not operator GO and not permission to execute the §6.7 graduation sequence until the body’s explicit operator-GO criterion is satisfied.
