+### Plan-Mode Gate
+
+When a session is in plan mode the message queue is not blocked — what changes is **how** each
+prompt is dispatched. While `plan_mode = 1` and `plan_approval_status = "awaiting_approval"` (or
+unset, pre-plan), every dispatched prompt runs as a planning turn (`planMode: true` in the command),
+so a follow-up sent before you approve is treated as an amendment and produces plan v2 — not
+blocked. Approve or reject flips `isPlanningTurn` to false; the next prompt then runs as a normal
+build turn. The full workflow (triggers, approval UIs, amendments, plan vs build model split) lives
+in [PLAN_MODE.md](PLAN_MODE.md).
+
+### Prompt-Safety Wrapping
+
+Bot-assembled prompts can contain untrusted text (a Linear issue body, a PR description, a Slack
+thread). To stop prompt injection across the trusted/untrusted boundary, the bots wrap each piece of
+user-supplied content in `` blocks via `buildUntrustedUserContentBlock` from
+`@open-inspect/shared` (HTML-escapes attributes, neutralizes literal `` inside the
+body). The sandbox bridge then wraps the whole prompt in `` when a plan or resume
+preamble is prepended, and also neutralizes literal `` so a user can't close the
+outer wrapper from inside.

+# Plan mode
+
+Get a plan before you get code.
+
+Plan mode is a human-in-the-loop gate. The agent reads your request, proposes a markdown plan, and
+stops. Nothing touches your branch until you approve. You can amend, reject, or accept — and you
+pick which model implements the approved plan.
+
+Use it when the task is non-trivial: refactor, redesign, multi-file change, architectural decision.
+Skip it for typos, one-line fixes, or anything you can describe in a sentence.
+
+## When plan mode kicks in
+
+Plan mode is on by default for non-trivial requests, off for quick ones. The behavior is the same
+across channels with one twist per channel.
+
+| Channel | Default | How to force ON | How to force OFF |
+| ---------- | ----------------------------------------- | --------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------ |
+| **Web** | The `Plan` toggle in the composer is OFF. | Click `Plan` before submitting. The model selector swaps to the deployment's plan model. | Leave the toggle OFF. |
+| **Linear** | OFF unless labelled. | Add the `plan` label (or `plan-` to also override the plan model). | Remove the label. |
+| **GitHub** | OFF unless labelled. | Same labels as Linear: `plan` or `plan-`. | Remove the label. |
+| **Slack** | The bot decides from your message text. | Either enable `Plan first, then build` in App Home, or write a prompt the classifier recognizes as plan-worthy. | Phrase your message as a small, well-scoped change ("quick fix", "rename", "small enhancement"). |
+
+The Slack classifier reads your `@mention` and picks plan-vs-build. A "refactor the auth module to
+use the new pattern" triggers plan mode; a "fix the typo in the homepage hero" goes straight to
+build. The App Home toggle, when on, forces plan mode on every session regardless of phrasing.
+
+## What happens when plan mode is on
+
+1. The agent runs a planning turn. It can read files but cannot edit, run shell, or open a PR.
+2. It produces a markdown plan with: a one-sentence restatement of your goal, an ordered list of
+ concrete steps, and a short "Risks & open questions" section if anything is uncertain.
+3. The session waits. The plan card carries a `Plan v1` header and an approval banner.
+4. You **approve**, **reject**, or **amend** by sending a follow-up prompt.
+
+The plan persists across turns. If you come back tomorrow, the next prompt re-anchors on the saved
+plan instead of relying on conversational memory that may have been compacted.
+
+## Approve, reject, amend
+
+### Web
+
+The approval banner sits above the composer with a `Build with` model picker and two buttons:
+`Approve` and `Reject`. Approving dispatches an "Implement the approved plan vN" prompt with your
+chosen model. Rejecting prompts for an optional reason and pauses the session. Clicking the
+`Plan vN` pill scrolls to the top of the plan card.
+
+### Linear
+
+The bot pushes the plan to the issue as an elicitation activity. Reply in the same thread:
+
+- `approve` — start the build (uses the model from a `model-` or `build-` label on the
+ issue, else the default)
+- `reject` — discard the plan; optionally add a reason on the same line
+- Anything else — the agent treats it as an amendment and proposes plan v2
+
+Switch the build model by adding a label like `build-sonnet` or `model-opus` before approving.
+
+### GitHub
+
+Same commands as Linear (`approve`, `reject [reason]`), posted as a PR or issue comment. Labels for
+model overrides: `plan-`, `build-`, `model-`, `review-`.
+
+### Slack
+
+The bot posts a `Plan v1 — awaiting your approval` block with the plan body and three buttons:
+`Approve`, `Reject`, and `View plan in web`. Approve opens a modal to pick the build model. Reject
+opens a modal for an optional reason. Both close cleanly when submitted.
+
+## Models
+
+Plan mode uses two models per session:
+
+- **Plan model** — runs the planning turn. Defaults to the deployment-wide `defaultPlanModel`
+ (configurable in **Settings → Models → Default Models**).
+- **Build model** — runs the implementation turn after approval. Defaults to `defaultModel`, but you
+ can switch it per session at approve time.
+
+The split matters: planning benefits from a more capable model since the resulting plan steers the
+implementation; the build model can be cheaper. The deployment defaults are stored in D1 and read by
+every bot at session-creation time — no Terraform redeploy needed to change them.
+
+### Label aliases (Linear + GitHub)
+
+Linear forbids `:` in label names, so we use dash-separated everywhere:
+
+| Label | Effect |
+| ---------------- | ---------------------------------------------------------- |
+| `plan` | Trigger plan mode (plan model = deployment default) |
+| `plan-` | Trigger plan mode AND override the plan model |
+| `model-` | Override the build model |
+| `build-` | Same as `model-`, reads more naturally in plan mode |
+| `review-` | Override the model used to auto-review a PR |
+
+`` is the short name: `sonnet`, `opus`, `haiku`, `opus-4-7`, `gpt-5.4`, etc. The alias →
+canonical model map lives in `@open-inspect/shared` so Linear and GitHub stay in sync.
+
+## Settings → Models
+
+Two dropdowns under **Default Models** read and write the deployment-wide defaults. Changes are
+atomic; disabling a model that's the current default is blocked inline.
+
+Bots (Linear, GitHub, Slack) call `GET /model-preferences` at session-creation time. Fallback chain:
+`D1 > env var > shared constant`. If the control plane is unreachable, bots fall back to the shared
+constant.
+
+## Slack specifics
+
+### App Home toggle
+
+`Plan first, then build` — when ON, every session you start in Slack is gated by a plan. When OFF
+(the default), the bot decides automatically from your prompt.
+
+The toggle is per-user and stored in KV (`user_prefs:`). Your toggle doesn't affect
+anyone else.
+
+### Smart detection
+
+When the toggle is OFF, the repo classifier also decides plan-vs-build. It runs as part of the same
+LLM call that picks the repo (or a dedicated lightweight call for the single-repo and channel-bound
+fast paths). Decision rules:
+
+- **Plan** — multi-step refactor / redesign / migration, feature spanning multiple files, "how
+ should we" questions, anything where reviewing the approach before code changes adds clear value.
+- **Build** — bug fix with clear scope, typo / rename / small enhancement, questions, explicit "just
+ do X" or "quick fix", read-only investigations.
+
+When uncertain, the classifier defaults to build to reduce friction. You can always re-prompt for a
+plan.
+
+## Architecture (high level)
+
+```text
+@mention / label / web prompt
+ │
+ ▼
+┌──────────────────┐ planMode flag ┌─────────────────────────┐
+│ control plane DO │ ───────────────────────▶│ sandbox bridge (Python) │
+│ SessionService │ │ _handle_prompt │
+│ plans table │◀── plan content ────────│ planning preamble + │

+ │ │
+ │ broadcasts: plan_status │ OpenCode (agent)
+ ▼ ▼
+ Web / Linear / GitHub / Slack callbacks Markdown plan emitted
+ │
+ ▼
+ approve / reject / amend ──▶ next prompt runs as build
+```
+
+Key invariants:
+
+- **Plan persistence** — plans live in the SessionDO SQLite `plans` table with monotonic versions
+ per session. v1 is `SUPERSEDED` once v2 lands. Approve/reject is terminal.
+- **Dispatch gate** — while `plan_mode = 1` and `plan_approval_status = "awaiting_approval"`, every
+ prompt is dispatched as a planning turn (amendments produce plan v2, v3, …). Approve or reject
+ sets `isPlanningTurn` to false and subsequent prompts run as build turns.
+- **Resume anchoring** — `_build_resume_preamble` injects the saved plan into the next prompt as
+ `…` so the agent re-anchors even after
+ context compaction.
+- **Prompt safety** — bot-assembled content is wrapped in `` blocks (HTML-escaped,
+ `` neutralized). The sandbox bridge wraps that block in `` and also
+ neutralizes literal `` to prevent injection across the outer boundary.
