**Resolves #12381**

Sub of epic #12377 (Track-1 cloud-deployment docs hardening). Backports this session's first-real-deployment frictions into `learn/agentos/cloud-deployment/` so a first-timer can deploy without hitting an undocumented wall.

**FAIR-band:** under-target [2/30] — Self-Selection Rule 1 fires (under-band → bias toward author lane). Docs-hardening sub of the cloud-deployment track.

**Evidence:** L1 (static — every documented friction was surfaced *empirically this session* while debugging the first real public cloud deployment: the connect-error ladder, the Caddyfile-baked-in rebuild, network-internal ports, the two auth layers, the `initialize` handshake, and the Colima bind-mount trap). Docs-only.

## What + Why

A first real deployment crosses several layers — the SDK's Host validation, the proxy's `Accept` / auth handling, the identity-header contract, the MCP handshake — and each fails with its own error and its own fix. The existing docs (a solid happy-path Day-0 tutorial) had no troubleshooting safety net. This adds the connect-error ladder + the deployment gotchas, and fills the genuine remaining Day0 gap.

## Deltas

- **`learn/agentos/cloud-deployment/Troubleshooting.md`** (new) — the connect-error ladder (`Invalid Host` → `Not Acceptable` → `302 sign_in` → `Missing proxy identity header` → `Server not initialized` → SSE framing), each error → which layer you cleared → the fix; plus the gotchas: Caddyfile-baked-in → `--build`, network-internal ports → `docker compose exec`, the two auth layers, the test-vs-prod profile, the verify-from-outside `initialize` handshake curl, and the empty-KB `count: 0` first-ingest gap. (Ticket items 1-7.)
- **`learn/agentos/cloud-deployment/Day0Tutorial.md`** — added the **Colima bind-mount gotcha** (a deploy path outside Colima's mounts silently resolves to empty VM-local dirs; `colima restart` does not fix it) + cross-links to the new troubleshooting guide. (Item 8 — the compose-plugin fix, `ai:sync-kb`-once, `-p` naming, and the Milestone 7 redeploy/handoff checklist were *already present*, so this adds only the genuine gap rather than re-stating them.)
- **`learn/tree.json`** — new "Connection Troubleshooting" nav leaf.

## Scope notes

- **Item 9 (redeploy-survival):** Day0 Milestone 7 + the Final Operator Handoff bundle are already concrete (persistent volume, backup mount, `down && up --build` healthcheck, query-survival, KB re-sync, tenant re-push, handoff doc), so this PR cross-links them to the new troubleshooting rather than duplicating.
- The `GET /health` auth-free liveness endpoint (flagged in the ticket as a companion idea) is **not** in this PR — it is a server feature, not docs; `Troubleshooting.md` notes its current absence. File separately if wanted.
- **Auth-login content** (PAT recipes) lives in #12380 (PR #12385) — deliberately not duplicated here.

## Test Evidence

Docs-only — no tests required (pr-review §7.5). `learn/tree.json` validated as parseable JSON with the new leaf present; `check-whitespace` clean; no decay-prone ticket-refs in the new prose.

## Post-Merge Validation

- [ ] Portal renders `Troubleshooting.md` + the new nav leaf with working cross-links.

## Dependencies

`Troubleshooting.md` cross-links `ClientAuthentication.md`, which lands in #12380 (PR #12385) — **merge #12385 first** (or together) so that link resolves on `dev`.

Refs #12377, #12380.

# PR Review Summary

**Status:** Approve+Follow-Up

*Cycle-1 reviewers: run §9.0 Premise Pre-Flight BEFORE composing Required Actions. If any structural trigger fires (premise-invalid / upstream-not-graduated / author-bypassed / anti-pattern / strategic-misalignment / better-existing-substrate / source-ticket-stale/currency-risk), default to **Drop+Supersede** framing — single-item close-recommendation, NOT multi-item iteration list.*

### 🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:
- **Decision**: Approve+Follow-Up
- **Rationale**: Approve+Follow-Up because the PR resolves #12381 as a focused docs-hardening sub while preserving the dependency on #12385 for `ClientAuthentication.md`. The missing link on this branch is intentional merge-order coupling, not an author-side change request.

**Peer-Review Opening:** This lands the right artifact for the first-deployment friction lane: a troubleshooting ladder that operators can scan by error signature, with Day0 kept as the happy path and only the genuine Colima gap added there.

### 🔬 Depth Floor

**Challenge OR documented search (per guide §7.1):**

**Documented search**: I actively looked for (1) whether #12381 was epic-labeled, (2) whether Day0 already covered the redeploy/handoff and compose/sync items the PR chose not to duplicate, and (3) whether the new troubleshooting claims map to actual config/source surfaces (`NEO_PUBLIC_URL`, `NEO_MCP_ALLOWED_HOSTS`, `trustProxyIdentity`, `mcpHealthcheck.mjs --url`, `Mcp-Session-Id`, and `Accept: application/json, text/event-stream`). I found no blocking concerns.

**Rhetorical-Drift Audit (per guide §7.4):**

Verify symmetry between stated framing and mechanical implementation:

- [x] PR description: framing matches what the diff substantiates (no overshoot)
- [x] Anchor & Echo summaries: N/A — no code/JSDoc anchor changes
- [x] `[RETROSPECTIVE]` tag: N/A — no retrospective tag in this docs PR
- [x] Linked anchors: #12371/#12383/#12385/#12380 dependency framing is consistent with the docs surface and PR body

**Findings:** Pass. I did not independently replay the external deployment session transcript, so I am treating the “surfaced empirically this session” provenance as author-sourced; the technical troubleshooting content itself was source-checked locally.

---

### 🧠 Graph Ingestion Notes

*   **`[KB_GAP]`**: Current KB retrieval is still behind the in-flight cloud-auth docs and PAT-mode work; reviewers should source-check against the PR branches and repo files until #12383/#12385/#12386 land.
*   **`[TOOLING_GAP]`**: No docs link checker caught the intentionally missing `ClientAuthentication.md` link on this branch; merge ordering must carry that guard.
*   **`[RETROSPECTIVE]`**: A troubleshooting ladder is the correct shape for multi-layer deployment friction: each error signature names the cleared layer and the next fix instead of spreading one-off notes through Day0.

---

### 🎯 Close-Target Audit

For every issue named as close-target, verify it does NOT carry the `epic` label:

- [x] Close-targets identified: #12381
- [x] For each `#N`: confirmed not `epic`-labeled

**Findings:** Pass — `gh issue view 12381` returned labels `enhancement` and `ai`, no `epic`.

---

### 📑 Contract Completeness Audit

- [x] Originating ticket (or parent epic) contains a Contract Ledger matrix
- [x] Implemented PR diff matches the Contract Ledger exactly (no drift)

**Findings:** Pass. The new `Troubleshooting.md` covers the connect-error ladder, Caddy rebuild, network-internal ports, auth-layer distinction, test-vs-production profile, outside-handshake curl, empty-KB gap, and `GET /health` current absence. `Day0Tutorial.md` adds the Colima bind-mount gap and cross-links the troubleshooting page. Existing Day0 content already covers the compose-plugin, one-shot sync, project naming, and Milestone 7 redeploy/handoff checklist, so the PR's non-duplication choice is correct.

---

### 🪜 Evidence Audit

- [x] PR body contains an `Evidence:` declaration line (or N/A justified inline)
- [x] Achieved evidence ≥ close-target required evidence, OR residuals are explicitly listed in the PR's `## Residual / Post-Merge Validation` section
- [x] If residuals exist: close-target issue body has the residuals annotated as `[L<N>-deferred — operator handoff needed]`
- [x] Two-ceiling distinction: PR body distinguishes "shipped at L<X> because sandbox ceiling" from "shipped at L<X> because author didn't probe further"
- [x] Evidence-class collapse check: review language does NOT promote L1/L2 evidence to L3/L4 framing without explicit sandbox-ceiling caveat

**Findings:** Pass for docs scope. Static verification is enough for this PR's docs/tree diff; the remaining observable surface is portal rendering and is already listed as post-merge validation.

---

### 📡 MCP-Tool-Description Budget Audit

**Findings:** N/A — no `ai/mcp/server/*/openapi.yaml` changes.

---

### 🔗 Cross-Skill Integration Audit

- [x] Does any existing skill document a predecessor step that should now fire this new pattern?
- [x] Does `AGENTS_STARTUP.md` §9 Workflow skills list need updating?
- [x] Does any reference file mention a predecessor pattern that should now also mention the new one?
- [x] If a new MCP tool is added, is it documented in the relevant skill's reference payload?
- [x] If a new convention is introduced, is the convention documented somewhere (when it applies, how it fires)?

**Findings:** All checks pass — this is cloud-deployment docs hardening, not a new agent workflow convention or MCP tool surface.

---

### 🧪 Test-Execution & Location Audit

- [x] Branch checked out locally (detached review worktree at `479b1aaad73b0194a16d4619c10b8cf1d5f698a0`)
- [x] Canonical Location: N/A — no test files changed
- [x] If a test file changed: N/A
- [x] If code changed: N/A — docs/tree-only diff

**Findings:** No tests needed (docs change). Verification performed: exact-head PR state/CI all green, #12381 label check, `git diff --check origin/dev..HEAD`, `learn/tree.json` JSON parse + new leaf lookup, local source/doc search for troubleshooting claims, link-target check for current-branch links, and Day0 Milestone 7 blame/search verification for already-existing redeploy/handoff content.

---

### 📋 Required Actions

No required actions — content eligible for human merge after #12385 lands so the `ClientAuthentication.md` cross-link resolves on `dev`.

---

### 📊 Evaluation Metrics
*   **`[ARCH_ALIGNMENT]`**: 93 - Keeps happy-path Day0 and error-path troubleshooting separated while linking both under the cloud-deployment tree.
*   **`[CONTENT_COMPLETENESS]`**: 91 - Covers #12381’s friction ledger and correctly avoids duplicating already-existing Day0 redeploy/handoff material.
*   **`[EXECUTION_QUALITY]`**: 89 - Docs/tree diff is clean and CI-green; the only caveat is merge-order dependency on #12385 for one cross-link.
*   **`[PRODUCTIVITY]`**: 94 - Converts a real deployment correction loop into a reusable operator runbook without fragmenting the ticket.
*   **`[IMPACT]`**: 84 - High impact for first public cloud deployments because it maps failure signatures to fixes.
*   **`[COMPLEXITY]`**: 40 - Low implementation complexity, moderate operational complexity because multiple transport/auth layers are being documented.
*   **`[EFFORT_PROFILE]`**: Quick Win - Small docs/tree patch with strong onboarding and debugging payoff.

Approved with the merge-order guard above. Human merge remains human-only.
