fix(cli): own a dedicated git repo at the project dir when nested in an enclosing repo (#282)

GitService.initialize() used checkIsRepo(), which is true whenever the project
dir sits anywhere inside a git working tree. So when a ktx project lived in a
subdirectory of an enclosing repo, ktx skipped `git init` and silently adopted
the enclosing repo as its store.

Every ktx relative path assumes the project dir IS the working-tree root. During
ingest, wiki/SL pages are written through a session worktree (whose root is the
worktree dir, so the page is recorded at repo-relative `wiki/global/<key>.md`)
and then squash-merged into the main worktree. With an adopted enclosing repo,
the main worktree's root is the enclosing git root, so the merge wrote the page
to `<gitRoot>/wiki/global/` — outside the project dir. reindex scans
`<projectDir>/wiki/global/`, found nothing, and wiki_search silently returned
empty (knowledge_pages = 0) even though ingest reported success.

Detect the project dir's own root with checkIsRepo(IS_REPO_ROOT) and initialize
a dedicated repo there unless the project dir is already a repo root. This keeps
adopting a user-created repo when the project dir IS that repo's root, fixes the
silent wiki/SL/memory divergence at its source for every writer, and stops ktx
from committing its scaffold into the user's enclosing repo.

Regression tests cover both layers: a project nested in an enclosing repo gets
its own .git (and the enclosing repo stays untouched), and a wiki page written
through a session worktree + squash-merge lands in the project dir and is
discovered by reindex.

 rules there with the same weight as the ones in this file.
 
+## Design Reasoning Defaults
+
+When proposing a design, an approach, or any non-trivial change, apply these
+defaults and run the self-check before presenting it. They encode the
+corrections users most often have to make; reaching these conclusions
+autonomously — without being asked the leading question — is the bar.
+
+- **MUST**: Optimize for the best outcome, not for an unstated constraint. Do not
+  silently adopt "smallest change", "least effort", "cheapest", or "least user
+  intervention" as the goal unless the user said so. Default to the most correct,
+  durable solution, and present cost / effort / scope as information for the user
+  to weigh — not as a ceiling you impose on their behalf.
+- **MUST**: Separate one-time cost from recurring cost before discarding an
+  option. A fixed cost paid once (a setup-time computation, an extra LLM call
+  during setup, a contract change) to make every later run cheaper or more
+  correct is usually worth it. Do not reject it with recurring-cost reasoning;
+  quantify both sides. (Example smell: "don't add an LLM call to a cost-cutting
+  feature" — wrong when the call is one-time and the savings recur.)
+- **MUST**: Treat a user's example as a representative of a class, not as the
+  spec. Design for the general population the example stands for, then stress-test
+  against deliberately different instances — another warehouse, dialect, stack
+  layout, or input shape — before committing. If a design only works because of an
+  incidental property of the example (e.g. "the noise happened to be in a separate
+  schema *on this demo*"), it is curve-fitting; generalize it or state the
+  assumption explicitly.
+- **MUST**: Prefer deriving from the system's own state over enumerating cases.
+  Favor an allowlist computed from declared/observed state (config, scanned
+  catalog, query log, the user's own inputs) over a denylist of known-bad
+  specifics (particular tables, schemas, tools, or vendors). A hardcoded or
+  hand-maintained list of external specifics is a smell: it rots and fails on the
+  next stack. The only acceptable static patterns are genuinely universal
+  invariants (e.g. DB-engine system catalogs) and ktx's own self-emitted
+  signatures.
+- **MUST**: Give each capability one implementation and route every caller
+  through it. When some behavior — running a query, resolving a credential or
+  config reference, authenticating, selecting a dialect, loading config —
+  already has a working implementation that some call sites use, make new or
+  divergent call sites depend on that path instead of standing up a second one.
+  Parallel implementations of one capability drift apart silently: a fix, a
+  newly supported input, or an added case lands on one path and not the other,
+  so one entry point (a CLI command, an MCP tool, an ingest stage) succeeds
+  while another fails on the same input. When two paths already do the same
+  job, collapse onto the shared one and delete the duplicate instead of
+  keeping both. When fixing a defect that lives on one path, fix the shared
+  implementation; do not patch the symptom on a forked branch, which preserves
+  the divergence you set out to remove.
+- **SHOULD**: Before inventing an abstraction or hand-rolling structural logic,
+  search for what already exists and reuse it — the codebase's canonical
+  representation (a structured ref/key type) instead of a parallel string scheme,
+  and a mandated/available tool (e.g. `sqlglot` for SQL structure; see
+  [SQL and Structured Parsing](#sql-and-structured-parsing)) instead of
+  hand-parsing. Normalize ambiguous input to the canonical form at the boundary;
+  do not carry the ambiguity downstream. This is the single-source-of-truth / DRY
+  item from the Priority Hierarchy applied at design time.
+
+Before presenting a design, answer these explicitly:
+
+1. Am I optimizing for a goal the user actually stated, or one I assumed?
+2. Does this generalize beyond the example in front of me? Name a real case where
+   it would break.
+3. Am I enumerating known-bad cases when I could derive scope from the system's
+   own declared/observed state?
+4. Is there an existing canonical representation or mandated tool I should reuse
+   instead of building or parsing my own?
+5. Am I discarding the better option on a weak or misapplied constraint
+   (one-time vs recurring cost, "more surface area", "more work now")?
+6. Does another entry point already perform this operation through a shared
+   implementation? If so, am I routing through that path instead of forking a
+   parallel one — and if I'm fixing a bug, am I fixing the shared layer rather
+   than one branch?
+7. Am I adding a user-visible option or alternate runtime path that the user did
+   not ask for? If yes, can one opinionated default solve the problem instead?
+8. Does this option multiply behavior by caller path, config value, or local
+   state? If yes, remove it unless it is explicitly required.
+
+A user question that nudges toward an alternative ("would X help?", "should I
+always do Y?", "will you hardcode Z?") is a signal that a better option exists.
+Investigate the implied direction and reason it through *before* defending the
+original proposal — and prefer to have asked yourself the question first.
+
+Example: If generated context changes should be saved, choose one save policy
+and route ingest, setup, memory, indexing, and docs through it. Do not add an
+`auto_commit`-style switch unless the user explicitly asks for staged-only runs
+and accepts the extra runtime path.

-# Goal
-
-Set up **ktx** from scratch end-to-end as a fully autonomous, agent-driven replacement for the interactive `ktx setup` wizard. Detect the environment, install missing prerequisites, ask the user only for information you genuinely need (which connections to add, credentials), write a valid configuration, verify it works, and run a fast ingest. Keep the user updated throughout.
-
-# Operating principles
-
-- **Be autonomous.** Detect, decide, and act. Only ask the user when you need information that only they can provide: project location, which databases/sources to connect, credentials, and similar choices.
-- **Stream short status updates.** Before each major phase ("Checking prerequisites…", "Installing uv…", "Configuring warehouse connection…", "Running fast ingest…") print a one-line update. Not chatty - just enough that the user can see what's happening.
-- **Verify against docs, never guess.** CLI flags, config keys, and command names must come from the docs or from `ktx <command> --help`. If something looks wrong or missing, say so explicitly.
-- **Print every command you run and its exit code.** Terse, not silent.
-- **Fail loudly with cause + fix.** When a command fails: capture the exact error, identify the cause, change something, retry. Never retry an unchanged command. Exceptions for *known soft-failures* are listed in Phase 4 - handle those without retrying.
-- **No LLM-based ingestion in this flow.** Only `--fast` ingest. The user can run `--deep` later.
-- **Platform-agnostic.** Detect the host OS first and pick the right install commands / path syntax. Anything path- or shell-specific must branch on OS.

-**ktx** docs are served at `https://docs.kaelio.com/ktx/`. **Start by fetching `https://docs.kaelio.com/ktx/llms.txt`** to discover the docs map. Scan it for a "troubleshooting" entry - if one exists, read it **before** running install/setup so you can apply known fixes preemptively rather than after failing. If no troubleshooting page is listed (current state of the docs), proceed. Then fetch any other `.md` pages you need (setup, ingest, status, connection types). **Never invent CLI flags or config keys** - verify against the docs or `ktx --help` / `ktx <subcommand> --help`.
-
-> **Note on the `ktx status` JSON example in the docs.** The docs page for `ktx status` shows an example shaped like `{"title": "...", "checks": [...]}`. That example is outdated. The real CLI output uses a top-level `verdict` field plus a `connections[]` array - see Phase 5 for the canonical success criteria. Trust the shape in this prompt over the docs example.
-
-# Workflow
-
-## Phase 1 - Detect environment
-
-Determine the host OS (e.g. via `uname -s`, `process.platform`, or `$env:OS`). Use the right install commands per OS for the rest of this flow.
-
-| Tool | macOS / Linux | Windows (PowerShell) |
-|------|---------------|----------------------|
-| `uv` | `curl -LsSf https://astral.sh/uv/install.sh \| sh` then re-source shell env | `irm https://astral.sh/uv/install.ps1 \| iex` |
-| Node.js | use system / fnm / nvm - **do not** auto-install | use system / nvm-windows - **do not** auto-install |
-| **ktx** CLI | `npm install -g …` (see Phase 2) | `npm install -g …` (see Phase 2) |
-
-If Node.js is missing, **stop and ask the user** to install it (https://nodejs.org/). Do not attempt to auto-install Node.
-
-## Phase 2 - Verify and install prerequisites
-
-Check each tool in order; install only if missing.
-
-1. **Node.js** - run `node --version`. Require >= 22. If missing or older, stop and instruct the user.
-2. **`uv`** - run `uv --version`. If missing, run the OS-appropriate install command, then re-source the shell environment (`export PATH="$HOME/.local/bin:$PATH"` on Linux/macOS) so `uv` is on `PATH`.
-3. **ktx CLI** -
-   - Install ktx with `npm install -g @kaelio/ktx`
-   - Verify with `ktx --version`.
-
-Print one status line per tool ("✓ uv 0.11.15 found", "Installing uv…", "✓ ktx 0.x.y installed").
-
-## Phase 3 - Gather user choices
-
-Ask the user (grouped if your harness supports it; otherwise sequentially):
-
-1. **Project directory.** Default: current working directory. Confirm before continuing.
-2. **LLM provider.** Default: `claude-code` with model `sonnet` (the user is already inside Claude Code; no extra API key needed). Offer `anthropic` (paste API key, stored as `env:` or `file:` ref) and `vertex` (GCP project + location) as alternatives. Skip if defaults are accepted.
-3. **Embeddings backend.** Default: `sentence-transformers` (local, no API key, managed Python runtime). Offer `openai` only if the user has a key.
-4. **Database connections.** Ask how many to add, then loop. For each, collect:
-   - Connection name (e.g. `warehouse`, `analytics`).
-   - Driver: one of `sqlite`, `postgres`, `mysql`, `sqlserver`, `bigquery`, `snowflake`.
-   - Connection URL/DSN (or service-account file for BigQuery). Accept `env:VAR_NAME` or `file:/abs/path` to avoid pasting raw secrets.
-     - **Heads-up for the user**: even if they paste a literal URL, **ktx** will silently relocate it into `<project>/.ktx/secrets/<connection>-url` and rewrite `ktx.yaml` to `url: file:…` - this is correct, secure behavior and not a bug.
-   - Schemas / datasets to include (postgres / sqlserver / snowflake / bigquery only).
-   - Optional `enabled_tables` allowlist if the user wants to scope ingest to specific tables.
-5. **Context sources** (dbt, Metabase, Looker, LookML, MetricFlow, Notion). Default: none. Ask only if the user mentions them.
-
-## Phase 4 - Configure the project
-
-Drive the existing wizard non-interactively (verify exact flag names with `ktx setup --help` and the docs - the automation flags are hidden from help but accepted):
-
-```
-ktx setup \
-  --project-dir <path> \
-  --no-input --yes \
-  --llm-backend <claude-code|anthropic|vertex> --llm-model <model> \
-  [--anthropic-api-key-env ANTHROPIC_API_KEY | --anthropic-api-key-file <path>] \
-  [--vertex-project <p> --vertex-location <loc>] \
-  --embedding-backend <sentence-transformers|openai> \
-  [--embedding-api-key-env OPENAI_API_KEY] \
-  --skip-sources \
-  --database <driver> --database-connection-id <name> --database-url <url|env:VAR|file:/path> \
-    [--database-schema <schema> …]
-```
-
-Notes on the flags above:
-- **Project creation is automatic with `--no-input --yes`.** When
-  `ktx.yaml` exists, setup resumes it. When it doesn't exist, setup creates it
-  at `--project-dir`.
-- **`--database-connection-id` is dual-purpose.** With `--database` or
-  `--database-url`, it names the new connection. Without those flags, it
-  selects an existing connection id.
-- **Configure one new database connection per setup command.** If the user
-  wants multiple new connections, run setup again for each connection.
-- **You don't need `--skip-agents` in this flow.** The agent integration step
-  is opt-in: setup leaves it alone unless you pass `--agents --target
-  <target>`.
-- **`--skip-sources`** is correct and is the documented way to leave context sources unconfigured.
-
-### Known soft-failure: `ktx setup` exits 1 after a successful fast build
-
-When you select a configuration that only does fast ingest, `ktx setup`'s final readiness verification fails with:
-
-```
-ktx context build did not pass agent-readiness verification.
-  <connection>: deep database context has not completed.
-```
-
-This is **expected** and **does not mean setup failed**. Treat the exit code as a soft-failure **only if all of the following hold**:
-
-- The build log shows the fast ingest reached `[100%] Scan completed` for every configured connection.
-- `ktx connection test <name>` (run next) exits 0 for every connection.
-- `ktx status --json --no-input` reports `verdict: "ready"`.
-
-If those three conditions hold, proceed to Phase 5 without retrying setup, and **do not** switch to `--deep` to "fix" the readiness gate - deep ingest is explicitly out of scope. Mention this in the final report under "Docs / CLI gaps" so the user is aware.
-
-If any of those three conditions do not hold, this is a real failure - capture the error, fetch the relevant docs page, fix the cause, retry.
-
-After `ktx setup` writes `ktx.yaml`, edit it directly for anything flags don't cover:
-- Per-connection `enabled_tables` allowlist (snake_case, under `connections.<name>.enabled_tables`).
-- Any advanced settings the user requested.
-
-Use a YAML-aware editor (e.g. `uv run python -c "import yaml; …"`) - do not hand-edit blindly.
-
-## Phase 5 - Verify
-
-`ktx setup` already runs a fast ingest of every database connection it configures, so you do not need to re-ingest by default. For each configured connection:
-
-```
-ktx connection test <connection-name>        # must exit 0
-```
-
-Only re-run ingest if setup's build log did **not** reach 100% for that connection:
-
-```
-ktx ingest <connection-name> --fast --no-input
-```
-
-**Mutex warning on `ktx ingest`**: passing both `--yes` and `--no-input` fails with `Choose only one runtime install mode: --yes or --no-input`. Setup already installed the managed Python runtime, so pass **only `--no-input`** to `ktx ingest`. (`--yes` is only needed when an ingest invocation has to install the runtime itself, which is not the case here.)
-
-Then run the global health check:
-
-```
-ktx status --json --no-input
-```
-
-Success requires (canonical shape - supersedes the example in the docs):
-- `verdict: "ready"` at the top of the JSON.
-- Every `connections[].status === "ok"`.
-- `ktx connection test <name>` exited 0 for every connection.
-
-Do **not** run `--deep` ingest in this flow - that requires LLM time and is out of scope.
-
-### Optional: directly probe the ktx daemon
-
-If the user asks for stronger verification that `sentence-transformers` is actually serving (not just that setup said "ok"), do all of:
-
-1. `ktx admin runtime status --json` → expect `"kind": "ready"` and `"features": [..., "local-embeddings"]`.
-2. `pgrep -fa ktx-daemon` → expect a process running `ktx-daemon serve-http`.
-3. `curl -sS http://127.0.0.1:<port>/health` → expect HTTP 200 with `{"status":"healthy",…}`.
-4. `curl -sS -X POST http://127.0.0.1:<port>/embeddings/compute -H 'content-type: application/json' -d '{"text":"hello"}'` → expect `{"embedding": [...384 floats...]}`.
-
-Discover the port from setup's log line `Started ktx daemon: http://127.0.0.1:<port>` or from the daemon's OpenAPI at `GET /openapi.json`. Note: the routes are `/health` and `/embeddings/compute` - not `/healthz` or `/embeddings`.
-
-## Phase 6 - Final report
-
-Print a structured report:
-
-```
-ktx SETUP COMPLETE
-
-Project:     <path>
-LLM:         <backend> / <model>
-Embeddings:  <backend> / <model>
-Runtime:     managed Python ✓ (if the ktx daemon was started)
-
-Connections:
-  - <name> (<driver>)  status=ok  schemas=[…]  tables=<N>
-  - …
-
-Sources:     <list or "none">
-Verdict:     ready
-```
-
-Then **Next steps** (copy-pasteable):
-1. Enrich with AI descriptions and embeddings: `ktx ingest <connection> --deep` (several minutes per connection).
-2. Add more connections later by rerunning this setup or via `ktx setup --database … --database-connection-id …`.
-3. Configure context sources (dbt, Metabase, Looker, LookML, MetricFlow, Notion) - see `ktx setup --help` for `--source …` flags.
-4. Install agent integration: `ktx setup --agents --target <claude-code|claude-desktop|codex|cursor|opencode|universal>` (with optional `--global` for `claude-code`/`codex`).
-5. Connect the agent / MCP: see docs at `https://docs.kaelio.com/ktx/`.
-
-Under **Docs / CLI gaps to flag** include any of these that applied during your run:
-- `ktx setup` exits non-zero after a successful fast build (deep-readiness gate); status reports ready.
-- `ktx ingest` rejects `--yes` and `--no-input` together; docs don't note the conflict.
-- `ktx status --json` real shape (`verdict`, `connections[]`) doesn't match the example in the docs page.
-- The pasted DB URL was moved to `.ktx/secrets/<name>-url` automatically.
-
-End with a single line: `RESULT: PASS` or `RESULT: FAIL - <one-line reason>`.
-
-# Operating rules (recap)
-
-- Print every command you run and its exit code. Status updates may be terse, but never silent.
-- On failure: capture the error, fetch the relevant docs page, fix the cause, retry. Never retry an unchanged command.
-- Known soft-failures (listed in Phase 4 and Phase 5) are not real failures - handle them as documented; do not retry or escalate.
-- If you find a docs/CLI gap ("docs say X but CLI does Y"), call it out in the final report.
-- Never commit credentials - **ktx** accepts `env:` and `file:` references; prefer those. **ktx** will also auto-relocate literal URLs into `.ktx/secrets/`, but that does not protect anyone who pasted the URL into chat history.

-## What this is for
-
-This page is for documentation consumption only:
-
-- answering questions about **ktx**
-- finding the right docs page
-- citing setup or CLI guidance
-- helping an assistant avoid stale or invented commands

-title: Agent Quickstart
-description: A task-first route for coding agents that need to understand ktx docs.
----
-
-This page is for coding assistants reading or citing the **ktx** docs. It is intentionally limited to documentation lookup, docs navigation, and safe command discovery.
-
-For Markdown endpoints, use [Markdown Access](/docs/ai-resources/markdown-access).
-For reusable task prompts, use [Prompt Recipes](/docs/ai-resources/prompt-recipes).
-To install **ktx** into an agent client, use [Agent Clients](/docs/integrations/agent-clients).
-
-## First read
-
-Agents should start with the smallest source that answers the task:
-
-1. [`/llms.txt`](/llms.txt) - discover the docs and preferred entry points.
-2. The relevant per-page Markdown URL, for example `/docs/getting-started/quickstart.md`.
-3. [`/llms-full.txt`](/llms-full.txt) - use only when the task needs broad context across many pages.
-
-## Task router
-
-| User asks the agent to explain... | Read first | Then read |
-|------------------------------------|------------|-----------|
-| What **ktx** does | [Introduction](/docs/getting-started/introduction) | [The Context Layer](/docs/concepts/the-context-layer) |
-| How to start from a checkout | [Quickstart](/docs/getting-started/quickstart) | [ktx setup](/docs/cli-reference/ktx-setup) |

-
-## Operating workflow
-
-Use this workflow when the user asks an assistant to answer a **ktx** docs question:
-
-1. Read [`/llms.txt`](/llms.txt).
-2. Pick the smallest relevant `.md` page.
-3. Use [`/llms-full.txt`](/llms-full.txt) only if the answer needs multiple sections of the docs.
-4. Quote commands exactly from the docs page.
-5. If a command affects a local project, ask the user before assuming credentials or live services are available.

-
-## Guardrails
-
-- Do not invent CLI flags. Fetch the relevant CLI reference page.
-- Do not scrape rendered HTML when a `.md` route exists.
-- Do not assume docs lookup requires agent-client configuration.
-- Do not include credentials or secrets in prompts, URLs, or copied docs snippets.

-
-## Index
-
-Fetch the curated index:
-
-```text
-https://docs.kaelio.com/ktx/llms.txt

-Use this file to discover high-value pages, task-specific entry points, and Markdown URLs.

-
-Every docs page has a Markdown route:
-
-```text
-https://docs.kaelio.com/ktx/docs/getting-started/quickstart.md
-https://docs.kaelio.com/ktx/docs/cli-reference/ktx-sl.md

-
-```bash
-curl -H "Accept: text/markdown" https://docs.kaelio.com/ktx/docs/getting-started/quickstart
-```
-
-## Recommended retrieval order
-
-1. Fetch `/llms.txt`.
-2. Select one or two relevant page Markdown URLs.
-3. Fetch `/llms-full.txt` only when page-level docs are not enough.
-
-## Output contract
-
-Markdown responses are designed for agent consumption:
-
-- Frontmatter is removed.
-- Each page includes a title, description, canonical URL, and Markdown URL.
-- Code blocks stay as code blocks.
-- Tables stay as Markdown tables.
-- Missing docs pages return a plain-text `404` instead of silently falling back to HTML.
-
-## Page actions
-
-Rendered docs pages include page-level actions near the title:
-
-- **Copy MD** copies the generated Markdown for the current page.
-- **View MD** opens the generated Markdown route.
-- **Copy MDX** copies the source MDX for the current page.
-
-## Common mistakes
-
-| Mistake | Better path |
-|---------|-------------|
-| Scraping the HTML page for a docs answer | Fetch the `.md` route instead |
-| Loading `/llms-full.txt` for a single CLI flag lookup | Fetch the relevant CLI reference page |
-| Treating `/llms.txt` as complete documentation | Use it as an index, then fetch linked pages |
-| Copying rendered text by hand | Use **Copy MD** or **Copy MDX** from the page actions |

+
+Print a shell completion script for **ktx**. Once installed, pressing <kbd>Tab</kbd>
+completes commands, subcommands, and flags, and - inside a **ktx** project - the
+names of things that already exist: semantic-layer source names for
+`ktx sl read` and `ktx sl validate`, wiki page keys for `ktx wiki read`, and
+configured connection ids for `ktx connection test`, `ktx ingest`, and
+`ktx sql`. This saves you from remembering exact source, page, or connection
+names.
+
+## Command signature
+
+```bash
+ktx completion <shell>
+```
+
+`<shell>` must be `zsh` or `bash`. The command writes the script to stdout; it
+does not modify any files. Enable completion by evaluating the script in your
+shell startup file.
+
+## Installation
+
+Add the matching line to your shell startup file, then restart your shell (or
+`source` the file). `ktx` must be on your `PATH`.
+
+```bash
+# zsh — add to ~/.zshrc
+eval "$(ktx completion zsh)"
+```
+
+```bash
+# bash — add to ~/.bashrc
+eval "$(ktx completion bash)"
+```
+
+To try it for the current session only, run the same `eval` line directly in
+your terminal.
+
+## What gets completed
+
+| Position | Completions |
+|----------|-------------|
+| `ktx <Tab>` | Top-level commands (`setup`, `sl`, `wiki`, `ingest`, …) |
+| `ktx sl <Tab>` | The `read` / `validate` / `query` subcommands |
+| `ktx sl read <Tab>` | Existing semantic-layer source names |
+| `ktx sl validate <Tab>` | Existing semantic-layer source names |
+| `ktx wiki <Tab>` | The `read` subcommand |
+| `ktx wiki read <Tab>` | Existing wiki page keys |
+| `ktx connection test <Tab>` | Configured connection ids |
+| `ktx ingest <Tab>` | Configured connection ids |
+| `ktx sql --connection <Tab>` | Configured connection ids |
+| `ktx completion <Tab>` | `zsh` or `bash` |
+| `ktx <command> --<Tab>` | The command's flags and inherited global flags |
+| `ktx sl --output <Tab>` | An option's allowed values (here `pretty`, `plain`, `json`) |
+| `ktx sl --connection-id <Tab>` | Configured connection ids |
+
+Source names, wiki page keys, and connection ids are read from the **ktx**
+project resolved from your current directory (or `--project-dir` /
+`KTX_PROJECT_DIR`). Outside a **ktx** project, completion still suggests
+commands and flags but no project entities. Bare `ktx sl <Tab>` and
+`ktx wiki <Tab>` complete subcommands instead of entity names because their
+positional arguments are free-text search queries.
+
+## Examples
+
+```bash
+# Print the zsh completion script
+ktx completion zsh
+
+# Print the bash completion script
+ktx completion bash

+### Profiling a slow ingest
+
+Each timed phase and work unit records a `durationMs` in the trace, and each
+agent loop records its step count and token usage. To see where wall-clock time
+went, enable profiling and **ktx** prints a rolled-up breakdown to stderr at the
+end of the run. There are two ways to turn it on, and two output formats.
+
+Turn it on per run with the `KTX_PROFILE_INGEST` environment variable, or
+persistently with `ingest.profile` in `ktx.yaml` (useful for CI or while
+iterating on a slow source):
+
+```bash
+KTX_PROFILE_INGEST=1 ktx ingest metabase       # human-readable table
+KTX_PROFILE_INGEST=json ktx ingest metabase    # raw JSON for coding agents
+```
+
+```yaml
+ingest:
+  profile: true   # human table; use "json" for the machine-readable form
+```
+
+Both formats report total wall time, time per phase, and the slowest work units,
+splitting each work unit's agent-loop time into model time versus tool-execution
+time. The `json` form emits the full structured profile (raw milliseconds and
+token counts, stable keys) plus a `summary.headline` one-line diagnosis, so a
+coding agent can parse it directly instead of scraping the table. If both the env
+var and the config request profiling, `json` wins. Example headline:
+
+```text
+Slowest phase: reconciliation (2m 05s, 48% of wall time). 2 work units (1 failed), ~88% model generation vs ~12% tools.
+```
+
+Work units run serially by default (`ingest.workUnits.maxConcurrency` is `1`);
+raise it in `ktx.yaml` if the profile shows the run is bound by serialized
+work-unit agent loops. If the provider reports an LLM rate limit, **ktx** shows
+a transient wait message and temporarily reduces effective work-unit concurrency
+according to `ingest.rateLimit`.

+- [`/llms-full.txt`](/llms-full.txt) - the entire docs corpus in one response.
+  Use only when a task needs broad context across many pages.
+- **Per-page Markdown** - append `.md` to any docs URL:

+
+### Retrieval order
+
+1. Fetch [`/llms.txt`](/llms.txt).

+## Agent instructions
+
+Paste this into a project or system prompt when an assistant needs to answer
+from the **ktx** docs:
+
+```text
+When answering ktx docs questions:
+
+1. Start with https://docs.kaelio.com/ktx/llms.txt.
+2. Fetch the smallest relevant Markdown page (append .md to its docs URL).
+3. Prefer the .md route over rendered HTML.
+4. Use https://docs.kaelio.com/ktx/llms-full.txt only when the task needs broad docs context.
+5. Quote commands exactly from docs pages.
+6. If docs and local CLI behavior disagree, say what differs and prefer local verified output.
+```
+
+## Prompts
+
+Replace project names, connection ids, and business terms with your own values.
+
+**Install and configure ktx in a project**
+
+```text
+Run npx skills add Kaelio/ktx --skill ktx and use the ktx skill to install and configure ktx
+```
+
+**Find the right command**
+
+```text
+Find the correct ktx command for this task: <task>. Start with /llms.txt, then fetch the smallest relevant CLI reference .md page. Quote the exact command and flags from the docs.
+```
+
+**Review semantic changes**
+
+```text
+Review the ktx semantic-layer and wiki changes in this branch. Check that measures have clear definitions, joins use valid keys, hidden or internal columns are not exposed to agents, and validation passes. List concrete file and line issues first.
+```
+
+## Guardrails
+
+- Do not invent CLI flags - fetch the relevant CLI reference page.
+- Do not scrape rendered HTML when a `.md` route exists.
+- Do not treat `/llms.txt` as complete documentation - use it as an index, then
+  fetch the linked pages.
+- Do not include credentials or secrets in prompts, URLs, or copied docs
+  snippets.
+- When docs and local CLI behavior disagree, prefer the local CLI output and
+  mention the mismatch.

+- Error class names and raw error messages.

+
+Error reports never intentionally include:
+
+- Secrets, credentials, API keys, tokens, cookies, signed URLs, or auth headers.
+- Database URLs, connection strings, DSNs, raw argv, or raw environment values.

+`ktx setup --llm-backend codex` makes **ktx** itself execute ingest, scan
+enrichment, memory, and other LLM-backed work through Codex.
+
+During runtime loops, **ktx** starts a temporary loopback MCP server for the

+read-only sandbox, sets `approval_policy=never`, auto-approves only those
+run-scoped MCP tools, and disables Codex web search.
+
+Codex backend isolation is currently limited by the public Codex SDK and CLI
+surface. Codex may still load user Codex config and built-in command execution
+or read-only file capabilities. Use `llm.provider.backend: claude-code` when
+you need stricter Claude-Code-style runtime tool isolation, or remove host

+## Context Layer and Context Engine
+
+Use **context layer** as the primary category term for what **ktx** provides to
+data agents.
+
+Use **context engine** as the secondary mechanism term for how **ktx** builds,
+maintains, validates, and serves that layer.
+
+| Concept | Use | Do not use |
+|---|---|---|
+| The whole **ktx** product category | **context layer** / **context layer for data agents** | knowledge layer, agent memory |
+| The active system that builds and maintains context | **context engine** | context layer when describing ingest/reconciliation internals |
+| The durable reviewed surface agents use | **context layer** | context engine |
+| The compiler pillar for executable metrics and joins | **semantic layer** | context layer when specifically discussing SQL compilation |
+| Prose/business knowledge files | **wiki** / **wiki pages** | wiki context |
+
+### Usage rules
+
+- Use **context layer** in taglines, page titles, meta descriptions, docs
+  introductions, comparison pages, and first-paragraph definitions.
+- Use **context engine** when describing active behavior: ingesting evidence,
+  reconciling changes, validating references, maintaining files, search, CLI,
+  and MCP serving.
+- Keep **semantic layer** for the narrower YAML/compiler surface: semantic
+  sources, measures, joins, dimensions, filters, SQL compilation, and semantic
+  queries.
+- Do not use **context engine** as the primary replacement for the whole
+  product. It sounds like runtime infrastructure; **context layer** better
+  describes the durable YAML and Markdown surface users review in git.
+- Do not use **context layer** when the sentence is specifically about the
+  compiler. Example: write "the semantic layer compiles semantic queries to
+  SQL," not "the context layer compiles semantic queries to SQL."
+- Default lowercase in prose: `context layer`, `context engine`, `semantic
+  layer`. Title case only in page titles, headings, nav labels, and UI labels.
+
