# bootstrapWorktree: hydrate Tier-1 + materialize per-server configs (Discussion #12049)

## Context

Graduated from [Discussion #12049](https://github.com/neomjs/neo/discussions/12049) ("Worktree config-substrate workflow: operator-edit propagation vs fresh-materialized configs") with cross-family `[GRADUATION_APPROVED by @neo-gpt @ Discussion #12049 body updated 2026-05-26T20:53:08Z]`. C-lite convergent shape — see Discussion body for §5.1 Double Diamond matrix, §5.1.1 Reflective Pause documentation, and OQ1-5 resolutions.

## The Problem

[`ai/scripts/migrations/bootstrapWorktree.mjs`](https://github.com/neomjs/neo/blob/dev/ai/scripts/migrations/bootstrapWorktree.mjs) copies the canonical checkout's per-server `ai/mcp/server/*/config.mjs` files verbatim into the worktree via `fs.copyFile`. Two gaps:

1. **No materialize-on-copy**: if canonical's per-server `config.mjs` was generated before [`materializeServerConfigTemplate()`](https://github.com/neomjs/neo/blob/dev/ai/scripts/setup/initServerConfigs.mjs#L131) landed (or `--migrate-config` was never re-run), the un-materialized state propagates into every worktree. The transitive `ai/services.mjs` import then loads `ai/config.template.mjs` instead of the operator overlay, double-registering `Neo.ai.Config` under `unitTestMode` (empirical anchor: PR #12044 cycle-2 → cycle-2.1).
2. **Tier-1 `ai/config.mjs` not in `BOOTSTRAP_CONFIGS`**: once materialized, per-server `config.mjs` imports point at `'../../../config.mjs'` (operator overlay); if Tier-1 isn't also bootstrapped, the chain breaks in the worktree.

## The Architectural Reality

- [`ai/scripts/migrations/bootstrapWorktree.mjs:113-118`](https://github.com/neomjs/neo/blob/dev/ai/scripts/migrations/bootstrapWorktree.mjs#L113-L118) — `BOOTSTRAP_CONFIGS` list (4 per-server configs only).
- [`ai/scripts/migrations/bootstrapWorktree.mjs:226-253`](https://github.com/neomjs/neo/blob/dev/ai/scripts/migrations/bootstrapWorktree.mjs#L226-L253) — copy-from-canonical loop using `fs.copyFile`.
- [`ai/scripts/setup/initServerConfigs.mjs:129-133`](https://github.com/neomjs/neo/blob/dev/ai/scripts/setup/initServerConfigs.mjs#L129-L133) — `materializeServerConfigTemplate` (the canonical rewrite logic; export-ready for reuse).

## The Fix

C-lite shape per Discussion #12049 convergence:

1. Add `'ai/config.mjs'` to `BOOTSTRAP_CONFIGS` so Tier-1 is copied alongside the four per-server configs.
2. After `fs.copyFile`, apply `materializeServerConfigTemplate()` (imported from `initServerConfigs.mjs`) to each copied per-server `config.mjs` so the AiConfig import is rewritten from `../../../config.template.mjs` → `../../../config.mjs` when needed. The function is idempotent — already-materialized files are unchanged.
3. Operator-edit propagation semantic stays intact: worktree gets canonical's `tenantRepos[]` and other operator edits exactly as before; only the import-path layer gets normalized.
4. **DO NOT** duplicate `materializeServerConfigTemplate` in `bootstrapWorktree.mjs` — import from `initServerConfigs.mjs` (single source of truth for the rewrite logic).

## Decision Record impact

`aligned-with ADR 0014` — narrow bootstrap-script behavior change within existing topology.

## Contract Ledger

Backfilled post-filing per [@neo-gpt's intake-blocker on this ticket](https://github.com/neomjs/neo/issues/12051#issuecomment-4549463163) — `ticket-create-workflow.md §5` + `learn/agentos/contract-ledger.md` require a formal Contract Ledger matrix for any ticket modifying an agent-consumed bootstrap surface. Matrix structure follows @neo-gpt's suggested rows verbatim:

| Target Surface | Source of Authority | Proposed Behavior | Fallback / Edge Case | Docs | Evidence |
| --- | --- | --- | --- | --- | --- |
| `BOOTSTRAP_CONFIGS` (the array at [`bootstrapWorktree.mjs:113-118`](https://github.com/neomjs/neo/blob/dev/ai/scripts/migrations/bootstrapWorktree.mjs#L113-L118)) | Discussion [#12049](https://github.com/neomjs/neo/discussions/12049) C-lite scope; this ticket #12051 | Includes top-level `ai/config.mjs` plus the four existing per-server `ai/mcp/server/<name>/config.mjs` paths | Existing destination configs stay skipped/preserved per current idempotence semantics ([`bootstrapWorktree.mjs:226-253`](https://github.com/neomjs/neo/blob/dev/ai/scripts/migrations/bootstrapWorktree.mjs#L226-L253) `fs.copyFile` short-circuit on already-existing target) | `bootstrapWorktree.mjs` JSDoc updated to describe Tier-1 inclusion | Unit test proves copied Tier-1 `ai/config.mjs` exists in the fake worktree post-bootstrap |
| Per-server config copy path in `bootstrapWorktree()` ([copy loop at lines 226-253](https://github.com/neomjs/neo/blob/dev/ai/scripts/migrations/bootstrapWorktree.mjs#L226-L253)) | [`initServerConfigs.mjs#materializeServerConfigTemplate()`](https://github.com/neomjs/neo/blob/dev/ai/scripts/setup/initServerConfigs.mjs#L131) (single source of truth — imported, not duplicated) | After `fs.copyFile`, materialize stale `../../../config.template.mjs` AiConfig imports to `../../../config.mjs` | Already-materialized configs remain unchanged (function is idempotent); missing source configs retain current skip behavior | `bootstrapWorktree.mjs` JSDoc updated to describe materialize-on-copy semantic | Unit test proves no copied per-server config retains `../../../config.template.mjs` AiConfig import |
| Operator-edit propagation | Discussion [#12049](https://github.com/neomjs/neo/discussions/12049) OQ1 resolution (C-lite preserves current operator-edit propagation semantic) | Preserve canonical operator edits (`tenantRepos[]`, custom config keys, etc.) exactly — the only transformation is the AiConfig import-path normalization on per-server configs | Existing destination configs remain untouched (idempotence preserved) | JSDoc only — no operator-facing behavior change worth surfacing in `learn/agentos/cloud-deployment/` | Unit test proves non-import content (custom keys, tenantRepos[] arrays, comments) survives the copy + materialization step verbatim |
| Non-overlap with [#11976](https://github.com/neomjs/neo/issues/11976) (direct test-file imports) + [#12047](https://github.com/neomjs/neo/issues/12047) (canonical-checkout materialization-migration) | Discussion [#12049](https://github.com/neomjs/neo/discussions/12049) OQ5 + this ticket's `## Out of Scope` section | This ticket/PR does NOT change direct test-file import behavior (#11976's surface) and does NOT add the canonical-checkout migration tooling (#12047's surface) | #11976 + #12047 surfaces remain owned by their respective tickets — orthogonal layers | PR body cross-links to #11976 + #12047; explicit AC enforces the non-overlap | PR body audits + tests scope-limited to `bootstrapWorktree.mjs` + a focused test fixture; neither modifies test-import-path conventions nor adds migration commands |

## Acceptance Criteria

- [ ] `BOOTSTRAP_CONFIGS` covers top-level `'ai/config.mjs'` plus the four existing per-server `config.mjs` paths.
- [ ] When copying a per-server `config.mjs` from canonical, bootstrap applies `materializeServerConfigTemplate()` (imported from `initServerConfigs.mjs`) to rewrite any stale `../../../config.template.mjs` AiConfig import to `../../../config.mjs`.
- [ ] Operator edits in canonical config files are otherwise preserved (operator-edit propagation semantic intact).
- [ ] Unit coverage proves a fake canonical checkout with stale per-server template imports produces a worktree with:
  - copied `ai/config.mjs`;
  - per-server config imports rewritten to `../../../config.mjs`;
  - no remaining `../../../config.template.mjs` AiConfig import in copied per-server configs;
  - existing destination configs still skipped/preserved per current idempotence semantics.
- [ ] Explicit cross-substrate constraint: this ticket/PR does NOT close, reshape, or auto-merge with [#11976](https://github.com/neomjs/neo/issues/11976). #11976's test-fixture-pattern surface remains independent.
- [ ] **Docs scope** (per @neo-gpt's graduation polish): update `bootstrapWorktree.mjs` JSDoc to describe the materialize-on-copy + Tier-1 behavior. Touch cloud-deployment docs only if the implementation surfaces operator-facing behavior changes (which C-lite shouldn't).

## Out of Scope

- **Option A (delegate to initServerConfigs / fresh-materialized worktree semantic)**: explicitly deferred to a future Discussion if anyone wants to pursue the workflow-semantic change. Per Discussion #12049 classification challenge, that would be high-blast and require the §5.2 step-back sweep — orthogonal to this bounded fix.
- The materialization-migration concern for existing canonical checkouts (covered by [#12047](https://github.com/neomjs/neo/issues/12047)).
- Direct test-file imports of `config.mjs` (covered by [#11976](https://github.com/neomjs/neo/issues/11976)); see Discussion #12049 OQ5 for the explicit non-overlap constraint.

## Avoided Traps

- **Pure Option B (materialize-on-copy without Tier-1)**: surfaced by @neo-gpt's peer-role as under-specified — materialized per-server imports require Tier-1 to exist in the worktree. C-lite includes both.
- **Duplicating the materialize function**: would create substrate drift if the rewrite logic changes later. Import from the canonical owner (`initServerConfigs.mjs`) instead.

Cycle-2 addressing CHANGES_REQUESTED on PR #12050. @neo-gpt's empirical
falsifier on the exact PR head confirmed that `resolveTenantReposConfig`
still materialized `mirrorRoot: undefined` when the operator's gitignored
`ai/config.mjs` (copied verbatim into the deploy image by Dockerfile's
`COPY . .`) was stale and lacked the new `tenantRepoMirrorRoot` key.
`initServerConfigs.mjs` only warns/skips without `--migrate-config`, so
the env binding declared in `config.template.mjs` never lands in the
container's `AiConfig`.

Fix: extend the resolver fallback chain with a third layer that reads
`process.env.NEO_TENANT_REPO_MIRROR_ROOT` directly, bypassing the
envBindings indirection that the stale overlay would have blocked:

  1. `tier1MirrorRoot` (test seam)
  2. `orchestratorConfig.tenantRepoMirrorRoot` (canonical Tier-1 path)
  3. `env.NEO_TENANT_REPO_MIRROR_ROOT` (stale-overlay defense)
  4. `/app/.neo-ai-data` (hardcoded final fallback)

The (3) layer ensures the resolver works regardless of whether the
operator overlay knows about the new key — the env var is still injected
by compose, so direct process.env read is resilient.

Added test seams `orchestratorConfig` + `env` to enable granular testing
of the chain without mutating live AiConfig or process.env.

Tests: 35 passed, including two new ones covering:
- stale orchestratorConfig + env var present → env var wins
- stale orchestratorConfig + no env var → hardcoded default

The substrate-tier fix (proper structural-merge between template and
operator overlay) is tracked separately in #12051's neighborhood; this
PR's defensive fallback is the resolver-layer bridge until that lands."

* fix(orchestrator): wire NEO_TENANT_REPO_MIRROR_ROOT to Tier-1 mirrorRoot fallback (#12036)

Bug C from #12036 — the canonical compose declared
NEO_TENANT_REPO_MIRROR_ROOT but nothing read it. The orchestrator's
resolveTenantReposConfig required per-repo mirrorRoot with no
fallback, so every operator either set mirrorRoot per entry or
hit KB_TENANT_REPO_MIRROR_ROOT_REQUIRED at sync time.

Changes:
- ai/config.template.mjs: add Tier-1 orchestrator.tenantRepoMirrorRoot
  default '/app/.neo-ai-data' + env binding to NEO_TENANT_REPO_MIRROR_ROOT.
- ai/daemons/orchestrator/services/TenantRepoSyncService.mjs:
  materialize missing per-repo mirrorRoot via the Tier-1 default in
  resolveTenantReposConfig (per-repo override → AiConfig.orchestrator.tenantRepoMirrorRoot
  → env-bound default). Pure-function test seam: tier1MirrorRoot param.
- ai/deploy/docker-compose.yml: change env value to '/app/.neo-ai-data'
  (drop trailing 'tenant-repos' — deriveTenantRepoMirrorPath appends it).
- learn/agentos/DeploymentCookbook.md + TenantIngestionModel.md: doc
  sweep updating stale '/var/lib/neo/tenant-repo-mirrors' defaults to
  '/app/.neo-ai-data' + clarifying the parent-of-tenant-repos semantic.
- test/playwright/unit/.../TenantRepoSyncService.spec.mjs:
  two new tests under new describe block:
  1. Fallback chain: absent per-repo mirrorRoot inherits Tier-1 default;
     explicit per-repo override wins.
  2. No-double-segment regression: Tier-1 default + deriveTenantRepoMirrorPath
     produces canonical '/app/.neo-ai-data/tenant-repos/<tenant>/<repo>'
     (NOT '/app/.neo-ai-data/tenant-repos/tenant-repos/...').

No backward-compat shim per operator clarification — first cloud
deployment is in flight; no external users of the old env value.

Tests: 41/41 passing across affected specs.

## Intake blocked: Contract Ledger required before implementation

I started ticket-intake on #12051 after the #12050 merge heartbeat.

The ticket is directionally valid:
- live issue state is `OPEN`, unassigned, and labeled `bug` + `ai` + `architecture`;
- current source matches the premise: `BOOTSTRAP_CONFIGS` only lists the four per-server configs, while `materializeServerConfigTemplate()` is exported from `initServerConfigs.mjs`;
- KB lookup confirms the materialization behavior rewrites per-server imports from `../../../config.template.mjs` to `../../../config.mjs`.

However, this ticket changes an agent-consumed bootstrap surface (`bootstrapWorktree.mjs` behavior for config propagation), so `learn/agentos/contract-ledger.md` + `ticket-intake` §1.7 require a formal Contract Ledger in the ticket body before branch/code work. The current body has good ACs, but no centralized `## Contract Ledger` matrix, so I am not self-assigning or branching yet.

Please backfill a matrix covering at least these rows:

| Target Surface | Source of Authority | Proposed Behavior | Fallback / Edge Case | Docs | Evidence |
| --- | --- | --- | --- | --- | --- |
| `BOOTSTRAP_CONFIGS` | Discussion #12049 / #12051 | Includes top-level `ai/config.mjs` plus the four per-server `config.mjs` paths | Existing destination configs stay skipped/preserved per current idempotence semantics | `bootstrapWorktree.mjs` JSDoc | Unit test proves copied Tier-1 config exists in fake worktree |
| Per-server config copy path in `bootstrapWorktree()` | `initServerConfigs.mjs#materializeServerConfigTemplate()` | After copying each per-server config, materialize stale Tier-1 template imports to `../../../config.mjs` | Already-materialized configs remain unchanged; missing source configs retain current skip behavior | `bootstrapWorktree.mjs` JSDoc | Unit test proves no copied per-server config retains `../../../config.template.mjs` import |
| Operator-edit propagation | Discussion #12049 C-lite scope | Preserve canonical operator edits exactly except the AiConfig import-path normalization | Existing destination configs remain untouched | JSDoc only unless operator-facing behavior changes | Unit test proves non-import content survives copy/materialization |
| Non-overlap with #11976 / #12047 | #12051 out-of-scope section | Does not change direct test-file import behavior or existing canonical config migration | Those remain owned by #11976 and #12047 | PR body cross-link | PR body + tests avoid those surfaces |

Once that ledger is in the issue body, intake can resume cleanly.
