Subject: [PATCH 01/80] docs: add Slack integration setup guide and app
 manifest

- SETUP.md: end-to-end walkthrough for creating the Slack app,
  installing it, wiring the MCP server, and troubleshooting
- slack-manifest.json: ready-to-paste Slack app manifest with
  user + bot scopes (search:read user-only)

Covers the pitfalls we hit: bot_user required for OAuth install,
search:read invalid as a bot scope, redirect URI registration for
amico slack login, and MCP server config in opencode.json.

+# Slack Integration Setup Guide
+
+How to connect Amicode to a Slack workspace so Amico can read messages, search history, and post on your behalf.
+
+## Overview
+
+Amicode talks to Slack through the [`slack-mcp-server`](https://github.com/korotovsky/slack-mcp-server) MCP package. Messages are sent **as you** (user OAuth token), not as a bot. The integration is outbound-only — Amicode calls the Slack Web API when you ask it to; there are no inbound webhooks or event subscriptions.
+
+The setup has four parts:
+
+1. Create a Slack app from a manifest
+2. Install the app and copy the User OAuth Token
+3. Register the localhost redirect URI (for `amico slack login`)
+4. Wire the MCP server into the Amicode config
+
+## Prerequisites
+
+- Admin (or app-install) permissions on the target Slack workspace
+- Node.js / npm installed (for `npx` to run the MCP server)
+- Amicode installed and running
+
+## Step 1: Create the Slack app
+
+1. Go to [api.slack.com/apps](https://api.slack.com/apps) → **Create New App** → **From a manifest**
+2. Select your workspace
+3. Paste the contents of [`slack-manifest.json`](./slack-manifest.json) (included in this directory)
+4. Click **Next**, review the summary, then **Create**
+
+### About the manifest
+
+The manifest defines a minimal Slack app with:
+
+| Section | What it does |
+|---------|-------------|
+| `bot_user` | Required by Slack's OAuth install flow — sits idle; you use the user token |
+| `bot` scopes | Valid bot-token scopes (everything except `search:read`, which is user-only) |
+| `user` scopes | The real permissions — read history, list channels/DMs, post messages, search, resolve users |
+| `socket_mode_enabled: false` | No inbound event delivery needed |
+| `is_hosted: false` | Not a Slack-hosted app |
+
+**Why both bot and user scopes?**
+Slack won't complete the OAuth install without a bot user, and a bot user needs at least one scope. The bot scopes mirror the user scopes minus `search:read` (which isn't valid for bot tokens — putting it there causes validation errors in Slack's manifest editor). In practice, Amicode only uses the **User OAuth Token** (`xoxp-…`).
+
+**Why `search:read` is user-only:**
+Slack's API restricts `search:read` to user tokens. If you add it under `bot` scopes, the manifest editor shows red validation errors on every bot scope line and the install fails.
+
+## Step 2: Install and get the User OAuth Token
+
+1. After creating the app, click **Install to Workspace** and authorize
+2. Go to **App Settings** → **OAuth & Permissions**
+3. Copy the **User OAuth Token** (starts with `xoxp-`)
+
+You do **not** need the Bot Token (`xoxb-`) or App Token (`xapp-`) — those are for the idle bot user.
+
+## Step 3: Register the OAuth redirect URI
+
+When you run `amico slack login`, it starts a local HTTP server to receive the OAuth callback. Slack rejects callbacks to unregistered URIs.
+
+1. In App Settings → **OAuth & Permissions** → **Redirect URLs**, add:
+   ```
+   http://localhost:54213/callback
+   ```
+2. Click **Save URLs**
+
+> **Note:** The port (`54213`) may vary between login attempts. If you see a `redirect_uri did not match` error with a different port, add that port's callback URL as well.
+
+## Step 4: Wire the MCP server into Amicode
+
+Add a `slack` entry under `mcp` in your Amicode config (`~/.config/opencode/opencode.json`):
+
+```json
+{
+  "mcp": {
+    "slack": {
+      "type": "local",
+      "command": "npx",
+      "args": ["-y", "slack-mcp-server"],
+      "env": {
+        "SLACK_TOKEN": "<your xoxp- user OAuth token>"
+      }
+    }
+  }
+}
+```
+
+Replace `<your xoxp- user OAuth token>` with the token from Step 2.
+
+The MCP package is **`slack-mcp-server`** by korotovsky (not `@anthropic/slack-mcp-server`).
+
+## Step 5: Reload and verify
+
+1. Reload the Amicode window: **Cmd+Shift+P** → **Developer: Reload Window**
+2. Open a **new chat session** (the + button)
+3. Ask Amico to send a test message, e.g.: *"message @someone in Slack saying hello"*
+
+If the MCP server loaded correctly, Amico will have access to tools like `users_search`, `conversations_add_message`, `conversations_history`, and `channels_list`.
+
+## Available Slack tools
+
+Once connected, these tools are available in every session:
+
+| Task | Tool | Key parameters |
+|------|------|----------------|
+| Read channel history | `conversations_history` | `channel_id`, `limit` |
+| Read thread replies | `conversations_replies` | `channel_id`, `thread_ts`, `limit` |
+| Send a message | `conversations_add_message` | `channel_id`, `text`, `thread_ts` (optional) |
+| Search messages | `conversations_search_messages` | `query`, `sort` |
+| List channels | `channels_list` | `limit` |
+| Find users | `users_search` | `query` |
+| Get unread messages | `conversations_unreads` | — |
+| Add/remove reaction | `reactions_add` / `reactions_remove` | `channel`, `timestamp`, `name` |
+
+## Troubleshooting
+
+| Problem | Fix |
+|---------|-----|
+| Install fails silently ("Click Create and Install to try again") | Make sure the manifest has a `bot_user` block and `is_hosted: false` in settings |
+| Red squiggles on all bot scopes in manifest editor | Remove `search:read` from `bot` scopes — it's user-token-only |
+| `redirect_uri did not match` error on login | Add the exact `http://localhost:<port>/callback` URL from the error to OAuth & Permissions → Redirect URLs |
+| Slack tools not available in session | Check that the `mcp.slack` block is in `~/.config/opencode/opencode.json`, then reload the window and start a **new** session |
+| Messages sent as bot instead of as you | Make sure you're using the User OAuth Token (`xoxp-`), not the Bot Token (`xoxb-`) |
+
+## File reference

+| File | Location | Purpose |
+|------|----------|---------|

+| `SKILL.md` | This directory | The amico-slack skill — tool reference and formatting rules |
+| `opencode.json` | `~/.config/opencode/opencode.json` | Amicode config — where the MCP server is registered |

Subject: [PATCH 02/80] docs(skills): rewire the spec-reviewer prompt + analyze
 off the dead P-list model

The amicode tail of the D6 consumer sweep (amico-strategy was #1317's
half; armonissa #105/PR #106 carries the vault half). The spec-reviewer's
conflict criterion now checks the live direction surface (PI-owned INTENT
+ conventions); the analyze skill triggers on 'direction needs informing'
with the D6 routing inline, and its Strategy Suggestions output becomes
Direction Suggestions reading the strategy brief. Zero live P-list
references remain in amicode skills.

'Seeded' means something now (plan-20260920 step 10):

- The pack schema gains the domain keys (additive, optional at the schema
  layer so the flagship stays valid): curricula, payload_schemas,
  verification (contract reference + claim-class bindings),
  instruments (with the coverage scope bound), benchmarks, first_task
  (with the shakedown/substrate level ladder). scores minItems relaxed
  deliberately: a seeded domain pack legitimately carries no composed
  scores yet — the quantum-era single-pack contract, not the general
  one (test updated to the new contract, reason inline).
- The pack lint: schema validation PLUS reference resolution (dangling
  refs = named findings) PLUS the seeded-key check — the flagship reads
  FORMALIZED (missing first_task), exactly the grandfathered design,
  and its snapshot-layout skill paths surface as the known real finding
  the step-14 formalization must reconcile (baked into the test so the
  reconciliation cannot land silently).
- The two seeded packs, each with a verification contract (tier
  assignments, claim-class bindings), the payloads doc, the first-task
  declaration (shakedown-marked, NOT yet run — exercised is a run
  state, never a manifest state), a curriculum skeleton authored to be
  filled from measured practice, and corrector integrity manifests
  (load-time shas, the #369 pattern — found by running the loader).

Verified: pack_lint 4/4 (EE + sensing seeded; flagship formalized with
the known finding); scores suite 323/323; schema 284/284; packaging +
gate_packs 65 passed. Loader loads all three packs clean (errors: []).

+**The task:** one non-QICK instrument class through the strumento device

+exercise (a real bench run) is the tracked next milestone, gated on
+hardware access that is not wired in this build — stated, not assumed.
+
+**The polyglot seam rides the same exercise:** the task record the mock run
+produces is written by the Python task-record writer and read by a Julia
+consumer — one round-trip exercising the contract's shape across languages.
+
+**Exit:** the run exists with a run ID, a tier-labeled verdict, and the task
+directory intact — then this pack is EXERCISED (shakedown), and this
+declaration updates to point at the run.

+stamped); downgrade/quarantine when an instrument is invalidated, cascading
+to the claims it certified. Historical records render `pre-tier` with
+provenance until retro-labeled via the deterministic class→tier table.
+
+**The task-record contract is the trust boundary:** the directory is the
+truth; verdicts forwarded from gates are re-derived from the record before
+routing; only declared gates forward at all; forwarding requires a
+non-empty `authored_by`.

+compute the filter response for a representative filter-function family
+against declared synthetic spectra, fold the verdict with confidence
+intervals (the estimation payload) end-to-end through the loop, tier-labeled

+Substrate-touching exercise (real NV data) is the tracked next milestone —

+**Exit:** the run exists with a run ID, a tier-labeled verdict with CIs,
+and the artifacts intact — then this pack is EXERCISED (shakedown), and this
+declaration updates to point at the run.

The D6 sweep's enumeration counted the spec-reviewer prompt and the
analyze skill as the last amicode-side dead-model refs, but
amico-schema-check's escalation step still told agents to append to
STRATEGY `## Agent Suggestions` (the line predates the sweep — it rode
in with the library-absorb chore). Same D6 routing as the analyze
rewrite: agents never edit the direction surface; the finding routes to
the amicissimo proposals surface.

Subject: [PATCH 05/80] docs(paper-mode): ADR-0023 + glossary for
 human-in-the-loop LaTeX co-editing

Records the Paper Mode design (epic #1620): a new committed-editing surface
with the live Draft as source of truth, agent edits proposed as reviewable
Pending Hunks, snapshot-base 3-way merge, per-hunk accept/reject with explicit
conflict resolution, manual gated compile, and ADR-0017 ledger provenance for
accepted hunks. Adds Paper Mode / Draft / Pending Hunk glossary terms.

+# Paper Mode: live-draft source of truth and snapshot-base 3-way merge for AI/human co-editing
+
+Status: proposed (2026-09-28)
+
+Tracking: harmoniqs/amicode#1620 · Glossary: `CONTEXT.md` (Paper Mode, Draft, Pending Hunk)
+
+Paper Mode is a new opt-in session surface for *committed* LaTeX writing (editor primary, Chat docked beneath, PDF right; distinct from Preview, which stays a viewer, and independent of the paused wide-mode work). It exists because Amicode has no safe surface for AI and human to co-edit the same `.tex`: today the agent reads a stale disk/cache snapshot (edits it "saw" go missing from its output), agent writes bypass the editor buffer (the human must reopen the file), concurrent edits clobber silently, and there is no way to review an agent change before it lands or to control when compilation runs.
+
+The decision is fourfold, and each part is hard to reverse because tooling, UI, and the mutation boundary all bind to it:
+
+1. **The live editor Draft is the single source of truth**, versioned by a monotonic Content Revision (extending the content-revision rule ADR-0013 already mandates). In Paper Mode the agent's Read/Edit tools read the Draft *at its current revision every turn* — never disk, never a cache. "The agent always sees my edits" becomes true by construction and checkable, because the revision it read is stamped. This supersedes the coarse revert-based fix in #1422, which only reverts a *clean* buffer and blocks while the human is typing — insufficient for real co-editing.
+
+2. **Agent edits propose to a review layer; they do not write disk.** An agent Edit/Write in Paper Mode produces Pending Hunks — inline diff decorations in the editor — leaving the Draft and disk unchanged until the human accepts. The human's own typing writes the Draft as normal and is always authoritative. Un-accepted agent text is therefore never in the file, which is what makes "the AI never interferes," "human always wins," and "nothing compiles behind my back" all fall out of one mechanism.
+
+3. **Concurrent edits reconcile via a snapshot-base 3-way merge.** The Content Revision the agent read at edit-start is captured as the merge base. At apply time we 3-way merge (base → human-edited Draft, base → agent hunks): non-overlapping regions land as Pending Hunks; regions both parties touched become **Conflict Hunks** the human must resolve. Conflicts are **never auto-resolved** — the human explicitly wanted to be able to check whether their text was removed. CM6's `@codemirror/merge` (already a dependency, already used in `editable-diff-view.tsx`) supplies the merge/decoration primitive.
+
+4. **Compilation is manual, on the accepted Draft.** It fires only on an explicit Compile action and compiles the Draft as it stands — Pending (un-accepted) Hunks are excluded because they are not yet in the file. Accepted hunks emit ADR-0017 mutation-ledger receipts (appearing in Files Changed with real provenance); pending and rejected hunks emit nothing.
+
+## Considered options
+
+- **Agent-writes-disk with a revert-style overlay (today's #1422 model), rejected.** Reachable from current code, but the agent's text *is* in the file before the human approves, so "human always wins," "review before it lands," and "compile only on approve" all become muddy special cases rather than consequences of the model. The dirty-buffer guard also silently blocks agent edits whenever the human is typing, which is the opposite of collaboration.
+- **CRDT live merge (Yjs), rejected for now.** A shared mergeable document gives Google-Docs-style seamlessness, but it is a heavy, hard-to-reverse architectural commitment, and per-hunk human review sits *on top* of it anyway. The snapshot-base 3-way merge delivers the reviewed-collaboration requirement with far less machinery; revisit only if real-time multi-human co-presence becomes a requirement.
+- **Promote Preview into a primary editor, rejected.** Reverses ADR-0013 and the glossary's deliberate "Preview = viewer" boundary and tangles viewer and editor responsibilities in one component. Paper Mode is a separate bounded surface instead.
+
+## Consequences
+
+The agent's Edit/Write tools gain a Paper-Mode-specific behavior (propose to the review layer instead of writing disk), which must fail closed — an agent edit that cannot be expressed as a Pending Hunk is surfaced, not silently written. The Draft/revision authority and the review/merge UI are new machinery, but both build on primitives that already exist (ADR-0013 content revisions, ADR-0017 receipts, `@codemirror/merge`). Paper Mode deliberately does **not** depend on the paused wide-mode work (#1434) and is built as its own layout. LaTeX language intelligence (#1513), SyncTeX (#1432/#1514), an outline navigator, and in-editor search (#1430) are out of scope — they dock into Paper Mode later as independent slices. Revisit this decision only if Amicode adopts real-time multi-human collaboration, at which point option 2 (CRDT) is the successor.

A user-invoked skill that shapes every response to lead with the answer/next
action, cut preamble and closers, number multi-step work, cap visible lists,
give concrete time estimates, and state errors matter-of-factly. Persists for
the session; toggled off with "normal mode"/"stop concise". Never auto-triggers.

Adapted (MIT) from ayghri/i-have-adhd, retuned for Amico's research-copilot
context and gate/verification/persona invariants.

Supersedes the response-presentation engine epic (#1330) for the 'toggle
concise on/off' need.

+## Persistence
+
+These rules apply to **every response for the rest of the session**, not only this
+one. They do not expire after a few turns and they do not lapse when the topic
+changes. If you are unsure whether they still apply, they do.
+
+Turn them off only when the reader says **"normal mode"** or **"stop concise"**.
+Confirm in one line, then return to your default style.

+1. Working memory is small. Anything not on screen is forgotten — do not ask the reader to "keep in mind X."
+2. Knowing the answer is not doing the answer. The gap between "got it" and "done it" is where work dies.
+3. Starting is the hardest step. The first action must be obvious, small, and doable now.
+4. Vague time estimates fail. "A bit of work" and "a few hours" register the same.
+5. Buried wins do not register. Visible progress matters.
+
+## Rules
+
+### 1. Lead with the answer or next action
+The first line is the answer, or something the reader can do — not context, not a plan.
+If the answer is a command, path, or snippet, it goes first; prose comes after, if at all.
+
+Bad: "Let's think about this. Your solve has a few moving pieces…"
+Good: "Pin the globals: set `fix_global_variable!(δ)` at `script.jl:42`, then re-run."
+
+### 2. Number multi-step tasks
+More than one step → a numbered list, each step one bounded action, no step with "and then" twice.
+Use the fewest steps that still work. A short path finished beats a complete path abandoned.
+
+### 3. End with one concrete next action
+If anything is open, name ONE thing doable in under two minutes ("open the file" counts).
+
+Bad: "Hope that helps — let me know if you want to dig deeper."
+Good: "Next: run the solve and paste the first `AMICODE_ITER` line."
+
+### 4. Suppress tangents
+Finish the first issue, then offer the second as a separate question. A question that
+comes up mid-work is not a tangent — answer it yourself if you can and fold it in;
+if it still needs the reader, surface it once, at the end.
+
+### 5. Restate state every turn
+The reader cannot hold "step 3 of 5" between messages. Restate it. If the harness has
+a todo/plan tool, use it for multi-step work — one item in progress at a time — and let
+the checklist do the restating instead of narrating the full plan as prose.
+
+### 6. Give specific time estimates, in concrete units
+Bad: "This will take some work." Good: "~15 min if the template covers it; an afternoon if not."
+
+### 7. Make completed work visible
+Show what now works, concretely. Do not bury the win in a recap.
+Good: "Solve converged: `F = 0.9982` in 137 iterations. Pulse at `runs/…/pulse.jld2`."
+
+### 8. Matter-of-fact tone for errors
+Never "Uh oh" / "Oh no" / "There seems to be a problem." State cause and fix.
+Good: "Solve failed at `iter 12`: `PosDefException`. Cause: Hessian not PSD. Fix: lower the trust-region radius."
+
+### 9. Cap visible lists to 5 items
+Group related items, rank the most relevant first, show at most five per group. Retain the
+rest internally; surface them when asked or when they become the next thing to address.
+This shapes **presentation only** — it must never limit analysis, tool results, search,
+candidate generation, or retained information.
+
+### 10. No preamble, no recap, no closing pleasantries
+Forbidden openers: "Great question," "Let me…," "I'll…," "Sure!," "Looking at your…," "To answer your question…"
+Forbidden recaps: "I've now done X, Y, and Z, which means…"
+Forbidden closers: "Let me know if you need anything else," "Hope this helps," "Feel free to ask."
+Start with the answer. End when the answer is done.
+
+## When to break the rules
+
+Override the defaults when:
+
+1. **The reader asks to "explain" or "walk me through."** Explain fully — still no preamble/closer, but the body runs as long as the topic needs. Add headers so they can skim back.
+2. **A destructive or irreversible action is ahead** (`rm -rf`, force push, a paid hardware/QPU submit, a schema migration, promotion to a shared vault/catalog). Confirm before acting — safety and the human gate win over brevity.
+3. **Debug spiral.** If the last three turns are "still broken," stop iterating on code: name the assumption that might be wrong and ask one diagnostic question.
+4. **Real ambiguity.** One short clarifying question beats guessing and rewriting.
+5. **A rule fights the task.** When a rule would delete the answer itself, the task wins, the shape stays. "What are my options?" gets 2–4 ranked options with one-line trade-offs, recommendation first — the options are the answer.
+6. **A rule fights the harness or the persona.** Amico's own contract outranks this skill: keep interview questions one-per-turn, announce tool calls when the harness requires it, honor every gate and verification step, and never let brevity suppress a caveat, an "untrusted until verified" flag, or a required confirmation. A `free`-tier fidelity is still untrusted and you still say so.
+
+## Pre-send check
+
+Before sending, delete:
+1. The first sentence if it announces what you are about to do.
+2. The last sentence if it asks "anything else?" or recaps what just happened.
+3. Any "by the way" sidebar.
+4. Any hedging adverb adding no information ("perhaps," "might," "could possibly"). Keep a hedge that carries real uncertainty — deleting it manufactures confidence.
+5. Any idiom or figurative phrase ("circle back," "on the same page"). Replace with the literal action.
+
+Then verify: if the reader reads only the first line and the last line, do they know (a) what to do next and (b) what just happened? If yes, send.

Subject: [PATCH 07/80] feat(app): concise-mode toggle in the composer bottom
 row
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A little icon-only toggle (the 'collapse' glyph) beside the report-bug button
that turns the concise skill on/off by sending its own toggle phrases
('concise mode' / 'normal mode'). ON state uses the accent selected-state
tokens (--accent-fill-soft + --accent-edge); aria-pressed + a state-dependent
label carry the meaning so color isn't the only signal. Both themes, focus
ring and tokens inherited from IconButtonV2.

Lightweight by design — drives the skill, not a persisted engine setting.
Part of the concise-mode feature (with the skill in this branch).

Subject: [PATCH 08/80] feat(app): concise mode as a composer switch, applied
 on send
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace the ambiguous collapse-icon button with a real switch (Concise). It no
longer sends its own message: flipping it sets a persistent per-session flag,
and while on, a concise directive is appended to the outgoing prose message at
submit time (normal turns only — shell/slash unaffected), so the response comes
back concise. User text and history stay unmodified.

- concise-mode-toggle.tsx: switch (checked/onChange) + label, replaces the icon button
- prompt-input-v2: controller exposes concise {on,set}; passed into createPromptSubmit
- submit.ts: PromptSubmitInput.concise; conciseDraftPrompt appends directive to the sent draft

App typecheck clean; materialize manifest refreshed.

Subject: [PATCH 09/80] fix(app): concise directive rides as invisible per-turn
 system, not visible text

The concise switch appended a bracketed directive to the sent message text,
which showed in the user's bubble. Move it to the message's per-turn `system`
instruction instead: it reaches the model for that turn but is not rendered as
a visible part. Threads system through FollowupDraft, the send call, the
optimistic message, and the server-compat prompt bridge (forwarded to
promptAsync's system). User text stays clean.

App typecheck clean.

Subject: [PATCH 11/80] fix(app): persist preview open-paths across editor
 reload (#1640)

Preview tabs were lost on webview reload: the active file lived in the
non-persisted ephemeral store and the full open-tab set only in
SessionPreviewTab's component-local workspace signal. Move both into the
persisted per-session SessionView store (previewActive + previewPaths),
reusing the serverGlobal machinery that already survives reload.

- layout.tsx: SessionView gains previewActive/previewPaths; previewFile
  getter/setter repointed from ephemeral -> persisted store; drop the
  ephemeral sessionPreviewFile.
- session-preview-tab.tsx: restore the workspace from the persisted list
  on mount (before the previewFile re-focus; idempotent), mirror open/close
  back up (gated on restore to avoid clobbering pre-hydration).
- session-side-panel.tsx: wire openPaths/onOpenedPathsChange at both sites.
- session-preview-tree.test.ts: open-paths round-trip invariants.

Split-pane layout stays out of scope (#981). Implements the #1398 wiring in
the persisted store so it covers reload as well as remount.

Subject: [PATCH 12/80] fix(app): gate preview restore on store hydration
 (fixes only-1-of-N)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The persisted layout store hydrates asynchronously. The first restore ran
before hydration (openPaths() still empty), the previewFile effect opened the
active file, restore then bailed on openedPaths().length>0, and the up-sync
wrote the shrunk [active] list back — clobbering the persisted list down to one
tab. Only the active file came back on reload.

Gate reconciliation on the layout store's `ready` signal (threaded in as
`hydrated`): hold both restore and up-sync until hydration completes, then MERGE
the persisted list with anything already open (union, persisted order) and keep
the active tab focused. Extract the merge into a pure `reconcilePreviewPaths`
helper and test it — the [a,b,c] vs open [c] -> [a,b,c] case is the regression.

Subject: [PATCH 13/80] chore(app-bundle): refresh manifest for
 preview-persistence overlay edits

Regenerate the overlay content hashes (refresh_manifest.mjs) for the four
files touched by this branch so the CI drift gate passes. Mechanical: the
committed manifest must match the overlay's hashes.

Subject: [PATCH 14/80] fix(app): rework preview persistence to Approach A
 (survives reload + tab-switch)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace the fragile reactive open-on-previewFile effect (the reopen/shift
engine, which re-fired on every #1288 re-instantiation) with a single
signature-guarded reactive restore that opens the persisted set idempotently —
once per distinct value — so it survives async hydration and late session-key
resolution and never loops or re-opens on a tab switch.

- Delete the on(previewFile) open effect; live opens arrive via the mount
  message listener; a first-open-that-mounts is folded into the restore target
  (previewPaths ∪ active) with one deduped post-merge write to persist it.
- Close reassigns previewActive to a remaining tab or null, so a closed file is
  never the active pointer that gets re-opened.
- Extract the restore/close decisions into pure, tested helpers
  (previewRestoreTarget / previewMissingPaths / previewActiveAfterClose) that
  the component uses — the '1-of-N', reopen, net-new and close-reassign
  regressions are now unit-tested (18 pass).
- Strip all debug diagnostics; refresh app-bundle manifest.

Design of record + breaking-point analysis: #1640. Supersedes #1398.

Subject: [PATCH 15/80] chore(app): strip preview-persistence debug diagnostics
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Remove the temporary [PVKEY]/[PVDBG] console probes used to trace the
cross-session bleed. Behavior unchanged; refresh app-bundle manifest.

Known limitation (tracked separately): opening a file in one session's
Preview can bleed into another session's Preview, because the prewarmer
keeps backgrounded session views alive and the preview-file bridge message
is an un-targeted window broadcast — every live SessionPreviewTab handles
it. Not catastrophic; needs a foreground-session gate / session-targeted
message to fix properly.

Subject: [PATCH 16/80] =?UTF-8?q?feat(app):=20responsive=20concise=20toggl?=
 =?UTF-8?q?e=20=E2=80=94=20hide=20when=20the=20composer=20is=20narrow?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The composer wrapper becomes a named query container (.amicode-composer-cq);
the concise toggle is wrapped and hidden via @container (max-width: 26rem) so
it disappears when the composer itself is narrow — window narrowed OR side
panel/split shrinks it — keeping the control row from crowding Send. Default
(wide) visible; container-query-keyed so it adapts to layout, not just viewport.

 =?UTF-8?q?=20composer=20remount=20=E2=80=94=20session-keyed=20store=20(#1?=

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The switch was a createSignal in the composer controller (per-instance
state), so the new-chat -> session handoff and the Changes-tab remount
reset it to off. Hold it in a module-level in-memory store keyed per
session; a new chat writes under its draft key, promoted to the session
key at session creation beside the agent/model promotion.

Closes #1651

Shard merges are #1302's by-hand flow (shard-watch is detection-only, #1306),
and the hand-run re-home of the 2026-10-01 macbook shard doubled path
segments on two home prefixes — directories that exist nowhere, sessions
invisible to every panel listing. The re-home is now tooling, not SQL by
hand: one explicit prefix substitution (client home → hub home; doubling
is structurally impossible — the candidate is exactly hubHome +
from.slice(clientHome.length)), validated to exist on the hub before
writing, falling back to the shard's original directory when it does not
(invisible-but-truthful beats invisible-and-wrong). Dry-run by default;
--apply performs per-id UPDATEs and re-reads the touched rows to verify.

planRehome is a pure function of (rows, clientHome, hubHome, exists) with
the real doubled paths as regression fixtures; the verb's impure edges
(bridge, fs, env) are injectable, mirroring shard_watch.ts.

Verified: 9/9 new tests; typecheck clean; full amico-run suite 1772
passed with one pre-existing month-boundary flake in sessions_verb
(expected 2026-09 vs 2026-10, already under repair on the
sessions-index-month-boundary branch, passes on main); dry-run + apply on
a copy of the real canonical DB seeded with a fresh shard re-homed every
row to a real existing hub path with verification true.

The REMEMBER-family verb the pasqal-campaign lesson demanded: user corrections
observed in chat sessions used to evaporate; now they file. Deterministic
marker pre-filter (recall) over READ-ONLY chat-DB gathers → the ONE jev client
(precision: correction-noul + kind + severity, three questions one call,
receipts, fail-open) → clusters file skill-finding/skill-proposal notes at
status: open in the personal vault per the skills-integrity TEMPLATE shapes,
cross-pass dedup by UPDATE appends; P0/P1 ping via the amico-slack contract;
dry-run by default; watermark; a dashboards/user-corrections.md digest.

+// corrections_verb.ts — `amico corrections scan` (#1677): mine the chat DB for
+// user messages that CORRECT system behavior (the pasqal-campaign lesson: the
+// user's in-chat corrections are the highest-signal feedback the system gets,
+// and they used to evaporate), classify the residual with the ONE Jev client,
+// and file skills-integrity findings at `status: open` in the personal vault.
+//
+// DOCTRINE (the #1301/#1303/#1311 curation discipline, unchanged):
+//   deterministic rules are the front line — the marker pre-filter owns RECALL
+//   (a generous correction-signal regex + the junk-title vocabulary decide
+//   WHICH messages are worth a call); Jev owns PRECISION and the kind/severity
+//   labels, on the residual only, through the shared jev_client.ts (never a
+//   second client); one JSONL receipt per attempted call (the client's job);
+//   fail-open everywhere — no key, disabled, outage, or sub-threshold confidence
+//   degrades to digest-only, never to a failed pass.
+//
+// GATE (the skills-integrity charter): detection is the autonomous fast ring —
+// this verb files `open` findings and NOTHING more. Triage, fixes, proposals,
+// merges: human-gated, always. `not-a-correction` never files; below-threshold
+// confidence never files; unverified (jev unavailable) never files.
+//
+// CONVENTIONS: DRY-RUN BY DEFAULT (`--apply` writes findings + watermark +
+// digest + Slack ping — the sessions-verb house rule); the chat DB opens
+// READ-ONLY (`--db` flag → $OPENCODE_DB → the XDG default; sqlite_bridge.ts —
+// never a writable connection for the scan); the pass watermark lives in the
+// ops dir and applies ONLY when `--days` is not explicit (a backfill --days N
+// forces the full window, per the issue's AC); vault writes target the
+// personal mount (the amico-vault routing rule) — `--vault` overrides for

Subject: [PATCH 20/80] =?UTF-8?q?fix(amico-run):=20corrections=20scan=20tu?=
 =?UTF-8?q?ning=20=E2=80=94=20the=20pasqal=20backfill=20verdict=20(#1677)?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

Tuned against the live 30-day acceptance run (the issue's named tuning loop):
- recall markers strengthened (interrogative 'why are we', prescriptive 'we
  should', 'wtf', 'are we not', 'way too', display-drift 'not showing/in
  line') — the first pass missed the pasqal campaign's corrections entirely
- filing gate recalibrated 0.90 → 0.80: jev reads true corrections as
  behavior-gap with noul ≥ 0.94 but kind-confidence in the 0.80–0.90 band;
  the noul floor (≥ 0.5) is the corroboration that keeps 0.80 honest
- --max-jev default 200 → 400 (cost guard; the wider recall needs headroom)
- admitted_detail in the result JSON — the dry-run's tuning surface
- sqlite bridge maxBuffer 1MB → 128MB: the fleet-scale windowed gather blew
  node's default with ENOBUFS

Acceptance (live dry-run, 30d window): 1220 scanned → 151 candidates → 17
admitted in 9 clusters, the pasqal campaign corrections included as P1
behavior-gap; nothing filed (dry-run).

Subject: [PATCH 21/80] =?UTF-8?q?fix(amico-run):=20corrections=20scan=20?=
 =?UTF-8?q?=E2=80=94=20independent-review=20hardening=20(#1677)?=

The pre-merge reviewer pass (never the implementer) found the vault-write
layer too trusting; all findings fixed and pinned:

IMPORTANT:
- YAML scalar escaping for untrusted user text in evidence lines — a bare
  quote could end the scalar and inject frontmatter keys (file integrity +
  the dedup matcher both read it); backslash+quote escaped, whitespace collapsed
- collision-safe finding filenames — the pass-scoped seq could regenerate a
  triaged closed finding's exact name and silently overwrite it; bump until free
- atomic vault writes (tmp+rename, the house pattern) on every finding/UPDATE/
  digest path — a crash mid-write must never truncate the original claim

MINOR:
- findExistingScanFinding scans the frontmatter BLOCK only (body quotes could
  cross-match a pasted finding-like message)
- cluster severity = worst occurrence (a P2 cluster escalating to P1/P0 now
  files — and pings — at its true severity)
- true unverified count in JSON + digest overflow line (was silently capped)
- admission gated on a fully-ran pass (partial-failure verdicts no longer
  overstate the dry-run output)
- jev circuit breaker: 5 consecutive transport failures degrade the pass
  (a hanging endpoint no longer costs --max-jev × 10s of serial waiting)
- stale filingAdmits docstring (0.90 → 0.80), merged fs imports, dirname

Test gaps pinned: chmod-444 read-only AC, hostile-text YAML escaping,
closed-finding collision path, watermark-not-advanced on fail-open,
escalation ping. Suite: 37 corrections tests, package 1866 passed.

The papers' classic forms (2305.03261, 2508.19075): continuous core,
direct collocation, indirect/GRAPE contrast, free-time/min-time with the
floor-margin lesson, robustness ensembles. Intonatissimo gains the QILC
form (measurement model, matching NLP, ILC correction) and its required
display set (measurement models, pulse+correction plots per iteration,
convergence). Piccolissimo gains the spline-NLP form and its display set.
Lint: three cards, zero findings (pre-existing main failures unrelated).

+
+# Formulation display — the problem in classic optimization form
+
+House style, from the two papers: whenever a solve is described beyond a
+headline number, the optimization problem itself is **written out** —
+objective, constraints, dynamics — in the papers' notation. The
+direct-collocation paper (arXiv:2305.03261) is the canonical source for the
+DIRCOL forms; the global-control paper's Appendix G (arXiv:2508.19075) is
+the canonical source for the continuous core and the direct/indirect
+contrast. Equation pointers below cite those sources.
+
+The LaTeX idiom for all forms (the papers' `split` layout):
+
+```latex
+\begin{split}
+\underset{<variables>}{\text{minimize}}\quad & <objective> \\
+\text{subject to}\quad & <dynamics constraints> \\
+                       & <boundary conditions> \\
+                       & <bounds>
+\end{split}
+```
+
+## Form 1 — the continuous core
+
+Source: arXiv:2508.19075, App. G, Eq. (111). Over time-dependent state and
+control trajectories:
+
+$$\min_{x(t),u(t)} \int_0^T \ell(x(t),u(t))\,dt + \ell_T(x(T))
+\quad \text{s.t.} \quad \dot{x}(t) = f(x(t),u(t),t),\; x(0)=x_\mathrm{init}$$
+
+with the quantum Hamiltonian written in the affine control form
+(arXiv:2305.03261, Eq. (2)):
+
+$$H(\mathbf{a}(t)) := H_0 + \sum_i a_i(t)\,H_i$$
+
+Show this form when introducing a problem class or writing for an audience
+that thinks in continuous time; it is the parent of every discrete form
+below.
+
+## Form 2 — direct collocation (the house default)
+
+Source: arXiv:2305.03261, Eqs. (9), (10), (11). States and controls are
+decision variables jointly; dynamics are enforced as **equality constraints**
+between knots:
+
+$$\begin{split}
+\underset{z_{1:N}}{\text{minimize}}\quad & J(z_{1:N}) \\
+\text{subject to}\quad & f(z_k, z_{k+1}) = 0 \quad \text{(collocation, e.g. Pad\'e-integrator: } U_{k+1} - e^{-iH(\mathbf{a}_k)\Delta t}U_k\text{)} \\
+& U_1 = I_{2n} \\
+& |\mathbf{a}_k| \le \mathbf{a}_{\max}
+\end{split}$$
+
+with $z_k$ packing states and controls per knot. Two load-bearing practical
+notes from the paper, both worth stating when the form appears:
+
+- **Isomorphic representation.** Complex objects enter the real-valued NLP
+  via the isomorphism (reals-then-imaginary parts); the paper's tilde
+  notation ($\widetilde{U}$, $\mathrm{iso}(\cdot)$) is the house notation.
+- **Solver.** A large, sparse nonlinear program solved by an interior-point
+  solver (IPOPT); dynamically infeasible initial guesses are legitimate
+  starting points and often converge fast — a defining property of direct
+  methods.
+
+Show this form for essentially every Piccolo solve, spec card, or report
+finding that formulates a new problem.
+
+## Form 3 — indirect (GRAPE) contrast
+
+Source: arXiv:2508.19075, Eqs. (114)–(115). Optimize over controls only;
+states are retrieved by propagation:
+
+$$\underset{u_{1:N-1}}{\text{minimize}} \sum_{k=1}^{N-1} \ell(x_k(u_{1:k-1}),u_k) + \ell_T(x_N)
+\quad \text{s.t.} \quad |u(t)| \le u_{\max}$$
+
+Show this form **only as a contrast**: fewer variables, but every
+$x_k$-involving gradient must propagate dependence through the dynamics —
+intermediate-state constraints are hard to enforce and the control landscape
+is rough. The papers use it to justify the direct method; a report should
+do the same, not present it as a competing option we run.
+
+## Form 4 — free-time / minimum-time
+
+Source: arXiv:2305.03261, Eq. (22) and its warm-start continuation. Stage
+one solves a free-time problem (knot times $\Delta t_k$ are decision
+variables) for a regularized objective:
+
+$$\begin{split}
+\underset{z_{1:N}}{\text{minimize}}\quad & J_0 = Q\,\ell(\widetilde{U}_N) + R(\mathbf{a}_{1:N-1}) \\
+\text{subject to}\quad & \mathbf{P}^{(4)}(\widetilde{U}_{k+1},\widetilde{U}_k,\mathbf{a}_k,\Delta t_k) = 0 \\
+& \widetilde{U}_1 = I_{2n}, \quad |\mathbf{a}_k| \le \mathbf{a}_{\max}
+\end{split}$$
+
+Stage two warm-starts a time-minimizing objective
+$J = J_0 + D\sum_k \Delta t_k$ with a final-fidelity floor
+$\mathcal{F}(U_N) \ge \bar{\mathcal{F}}$ preventing the duration term from
+trading away the gate. **Always state the floor's relation to the achieved
+stage-one fidelity** — a floor at or above the achieved value is a
+guaranteed violation (a recorded lesson from the OQC campaign: set floors
+*below* achieved F with margin).
+
+## Form 5 — robustness ensembles
+
+House form for `SamplingProblem`: minimize a weighted sum (or the worst
+case) over an ensemble of perturbed systems:
+
+$$\underset{z}{\text{minimize}} \sum_j w_j\, J(z;\theta_j)
+\quad \text{s.t.} \quad \text{(per-member dynamics)},$$
+
+with $\theta_j$ the perturbation ensemble (drive scale, detuning, position
+jitter). When reporting: **nominal and worst-case are both stated, legs
+named** — the display-conventions honesty bar.
+
+## The per-solve display set
+
+What accompanies a stated problem, composing the plot skill's per-tier
+standards (never duplicating them):
+
+| Solve type | Always show |
+| --- | --- |
+| Gate / state synthesis | The stated form; pulse plot; populations or unitary-distance trace; convergence trace ($J$, $\texttt{inf\_pr}$, $\texttt{inf\_du}$) |
+| Free-time / min-time | The stated form **plus** the duration/fidelity trajectory and the floor margin |
+| Robustness ensemble | Nominal + worst-case, members overlaid; the per-member breakdown table |
+| Any free-phase solve | The virtual-Z frame note — which phases were free and their optimized values |
+
+## Where these render
+
+- **PI-report findings** (`pi-report` fill contract, amicode #1700): a
+  finding that formulates a new problem carries its classic form inline;
+  findings that reuse an established formulation name it and cite the spec.
+- **Demo/paper write-ups**: the form opens the methods section; the
+  run-dir artifacts back every number (display-conventions: a number
+  without an artifact is a claim).
+- **Spec cards**: the falsifiable acceptance entries pair with the formal
+  statement — state the problem, then the gates that adjudicate it.
+
+## Honesty bars (inherit `display-conventions`)
+
+- Legs named, never merged; the researcher's notation; provenance stamps.
+- Package-API terms are **mapped to math** here — the report shows math,
+  the run dir shows code. When mapping, cite the package's own docstring
+  or verified usage card (never invent an equation the package doesn't
+  solve — the anti-gaming rule applies to formulations too).

+## Display — the QILC problem in classic form
+
+A QILC write-up (report finding, demo, paper section) states the problem
+in classic optimization form, in the `formulation-display` house style,
+before any results. Three equations, all from the constructors above:
+
+**The measurement model.** Operators $\{M_j\}$ evaluated on the state at
+measurement knots $t_k$:
+
+$$y_k = \big(\langle\psi(t_k)| M_j |\psi(t_k)\rangle\big)_{j}, \qquad
+y_{\text{model}} = h(z) \ \text{(NLP rollout)}, \qquad
+y_{\text{exp}} = h_{\text{device}}(\text{pulse}) + \text{noise}$$
+
+**The measurement-matching subproblem** (`build_subproblem`): control NLP
+minimizing measurement error against shifted targets under a trust region:
+
+$$\begin{split}
+\underset{z}{\text{minimize}}\quad &
+\lVert y(z) - y_{\text{target}} \rVert^2_{Q_{\text{meas}}}
++ R_{\text{tr}}\lVert u - u_{\text{ref}}\rVert^2
++ R_{\theta}\lVert\theta - \theta_{\text{ref}}\rVert^2 \\
+\text{subject to}\quad & \text{trajectory dynamics (collocation)},\quad
+\text{control + global bounds}
+\end{split}$$
+
+with the option to compose the original objective (infidelity) in when
+measurement-matching alone does not drive fidelity.
+
+**The ILC correction** (`compute_ilc_targets`): the model error estimate
+$\hat\varepsilon = y_{\text{exp}} - y_{\text{model}}$ is pre-compensated
+into the targets,
+$y_{\text{target}} = y_{\text{goal}} + y_{\text{model}} - y_{\text{exp}}$,
+and the loop iterates solve $\to$ apply $\to$ measure with Armijo
+backtracking acceptance and the trust-region schedule $\gamma$; the
+convergence criterion is measurement error $\le$ `tol`.
+
+### The required display set (a QILC write-up always carries)
+
+1. **The measurement model, drawn**: the operators, their knots, the goal
+   targets $y_{\text{goal}}$ — a reader must see *what is being matched*
+   before any correction makes sense.
+2. **Pulse + correction plots, per iteration**: the applied pulse against
+   the nominal, and the correction $\delta u$ per accepted iteration —
+   the ILC's actual movement.
+3. **Convergence**: measurement error and objective per outer iteration,
+   accepted/rejected Armijo steps marked, trust-region radius against
+   iteration.
+
+A QILC result reported without these three is incomplete — the
+calibration tier's results live or die on whether the measurement model
+was honest, and only these displays let the reader check.

+
+## Display — the spline NLP in classic form
+
+A Piccolissimo write-up states the problem in the `formulation-display`
+house style, with the spline parameterization explicit. The controls are
+**spline coefficients at knots** (not per-timestep samples): the emitted
+waveform is by construction the spline the integrator integrates — that

+   trace; Altissimo's callback fields (`f_val`, `eq_viol`, `kkt_error`)
+   are the honest convergence line.
+3. **Slew/roughness against the bound** — the `du_bound` margin, since
+   the smoothness axis is Piccolissimo's reason for existing.
+
+## Cross-reference
+
+The adjoint-robustness objective's own form (when used) is stated
+alongside, from the robustness section above — a Piccolissimo report
+never presents robustness numbers without the objective that produced
+them.

+### Integrators (the dynamics constraint each one enforces)
+
+| Integrator | Form it enforces | Notes |
+| --- | --- | --- |
+| `HermitianExponentialIntegrator` (unitary / ket / multiket / sampling variants) | $U_{k+1} = e^{-iH(\mathbf{a}_k)\Delta t} U_k$ | The step's exponential evaluates via an internal Padé-13 approximation (source: `integrators_exponential/_exponential_integrators.jl`). The published Padé-integrator collocation form is the paper's $P^{(4)}$ (arXiv:2305.03261 §III-B) |
+| `NonhermitianExponentialIntegrator` (density / multidensity) | $\rho_{k+1} = e^{\mathcal{L}(\mathbf{a}_k)\Delta t}\rho_k$, $\mathcal{L}(\cdot) = -i[H,\cdot] + \text{dissipation}$ | Daleckii–Krein for the Fréchet derivative (`daleckii_krein.jl`) |
+| `BilinearIntegrator` | Piecewise-constant control, first-order | The simplest collocation step |
+| `SplineIntegrator` (Piccolo) | The constraint integrates the **exact spline waveform** reconstructed from knot values — the emitted pulse and the optimized pulse are the same object | Per trajectory type (unitary/ket/multiket/density/multidensity) |
+| Piccolissimo `SplineIntegrator` cores | Magnus series: `MagnusGL4Alg`, `MagnusAdapt4Alg`; `ChebyshevAlg` (ket); Duhamel for density (`density_duhamel.jl`) | State which core ran — they are different approximations, and "Magnus does not apply to the dissipative density ODE (non-skew rhs)" is a recorded lesson |
+| `SplitOperatorIntegrator` (Piccolissimo) | Strang split-step, matrix-free: kinetic factor $e^{-ik^2\Delta t/2m}$ (control-independent) + potential kicks; analytic JVP/VJP, no AD near the FFT | Atom-transport venue (issue #270) |
+| Tsit5 (explicit RK) | Adaptive rollout only | **Never** a collocation constraint; verification/rollout path — quote its agreement separately (density paths are Tsit5-primary + Tsit5-cross-check: weaker integrator independence, a recorded honesty note) |
+
+### Objective terms
+
+| Term | Classic form | Source |
+| --- | --- | --- |
+| `UnitaryInfidelityObjective` | $\ell(U) = 1 - \frac{1}{n}\lvert\mathrm{tr}(U_\text{goal}^\dagger U)\rvert$ | Paper Eq. (3), arXiv:2305.03261 |
+| `KetInfidelityObjective` | $1 - \lvert\langle\psi_\text{goal}\vert\psi_N\rangle^2\rvert$ | `objectives.jl` |
+| Free-phase variants (`UnitaryFreePhaseInfidelityObjective`, `KetFreePhase...`, `CoherentKetFreePhase...`) | Gate infidelity over the computational subspace **up to free per-component virtual-Z phases** — objective-only; the frame is exact software, never a cheat | `objectives.jl`; the free-phase-decisiveness convention |
+| `DensityMatrixInfidelityObjective` | $1 - \mathrm{tr}(\rho_\text{goal}\rho_N)$ (Hilbert–Schmidt) | `objectives.jl` |
+| `LeakageObjective` | $\lVert(I - \Pi)\psi_k\rVert^2$ at knot points | `objectives.jl` |

+| Slew / interior overshoot (`CubicSplineBoundConstraint`, `du_bound`) | The **emitted spline** stays within bounds between knots — the knot values alone do not guarantee it | `constraints_spline/`; the knots-vs-emitted distinction is load-bearing |
+| Leakage bound (`KnotPointConstraint` / `NonlinearKnotPointConstraint`) | $\lVert(I-\Pi)\psi(t_k)\rVert^2 \le \varepsilon$ at knots | `constraints.jl` |
+| `FinalUnitaryFidelityConstraint` | $\mathcal{F}(U_N) \ge \bar{\mathcal{F}}$ | `templates/minimum_time_problem.jl` |
+| `DurationConstraint` | $\sum_k \Delta t_k \le T_{\max}$ (or per-interval $\Delta t$ bounds) | `templates/`; per-interval floors encode physics (settling, clock) |
+| QILC trust region | $\lVert u - u_\text{ref}\rVert^2_{R_\text{tr}}$ recentered on $z_\text{ref}$ each iteration | The intonatissimo card |
+
+### Solvers
+
+| Solver | What it is | When stated |
+| --- | --- | --- |
+| IPOPT (via DirectTrajOpt) | Interior-point, exact sparse NLP | Every Piccolo solve; `exact_hessian=false` on MultiKet is a recorded caveat |
+| Altissimo (Piccolissimo) | Matrix-free interior-point; callback fields $f_\text{val}$, $eq\_viol$, $kkt\_error$ are the honest convergence line | Piccolissimo solves |
+| Gauss–Newton second-order mode | Matrix-free HVP composition | When Piccolissimo's GN default runs |
+| Armijo backtracking (ILC) | Accept/reject on objective descent; show accepted **and** rejected steps | QILC convergence displays |
+
+**Completeness rule.** A formulation statement that omits any row the
+problem actually used is incomplete — the reader must be able to

+is not in these tables (a new upstream constructor, an inline constraint),

 # Formulation display — the problem in classic optimization form
 
-House style, from the two papers: whenever a solve is described beyond a
-headline number, the optimization problem itself is **written out** —
-objective, constraints, dynamics — in the papers' notation. The
-direct-collocation paper (arXiv:2305.03261) is the canonical source for the
-DIRCOL forms; the global-control paper's Appendix G (arXiv:2508.19075) is
-the canonical source for the continuous core and the direct/indirect
-contrast. Equation pointers below cite those sources.

+These forms are **generated from the run's `formulation.toml`**, never
+hand-written from memory of the script (the formulation-record contract,
+amicode #1700/#1710). The renderer (`scripts/pi-report/render_formulation.py`)
+turns the record into the classic-form block; the agent writes the explanation
+*around* it — zero agent invention inside the math. Corrections target the
+record's source (the spec or the script) and re-render; a correction made in
+rendered prose is lost on the next render.
+

+clean display equation carrying symbols only — no `\text{}` sentences, no
+identifiers, no weights inside the math — then a single "Here, ..." prose
+paragraph carrying every detail: weights, integrator + algorithm, $N$,
+bounds, free-phase/free-time flags, solver. The equation states the shape;
+the prose carries the numbers.
+
+**Provenance rules the render obeys:**
+
+- `canonical` is **derived upstream** (retained spec, verified against the
+  object) — a kwargs-built problem renders as a *Non-canonical record*
+  (best-effort extraction) with its call-site `template_actuals` and
+  `solver_actuals` labeled as actuals, never as verified round-trips.
+- Call-site actuals **beat template-name inference**: a `SplinePulseProblem`
+  running PWC collocation (`integrator_type = "pwc"` in `template_actuals`)
+  renders piecewise-constant — never "spline-faithful" (the #540 case).
+- Raw matrices are capped to digest + dims (emission caps them in the record;
+  the render passes the capped marker through) — full matrices live in the
+  spec/script source, never in synced run dirs.
+- Receipt meanings: **UNBACKED** — no record in the run dir; any stated
+  formulation is unbacked. **PARTIAL-RECORD** — the record is missing
+  inventory rows (schema fields, objective weights, integrator, solver
+  actuals); fix the emission or the upstream extraction, not the render.
+  Unmapped record sections are preserved and named, never fatal.
+
+The fill contract (`../../../scripts/pi-report/FILL-CONTRACT.md` relative

+full report-side doctrine; this section governs the forms wherever they render.

+ * pdf-find-core — Pure find machinery for PDF panes (S1 of Cmd+F in Preview).
+ *
+ * Walks the pdf.js text layer ([data-pdf-text-layer] — styled by attribute,
+ * NOT the `.textLayer` class) under a PDF pane root and builds a normalized
+ * searchable string plus an offset map back into DOM (textNode, offset)
+ * pairs. `findMatches` scans that string and returns Ranges in document
+ * order, each tagged with its page number.
+ *
+ * Normalization:
+ *  - NFKC (the text layer is already NFKC-normalized by pdf.js's
+ *    streamTextContent, so ligatures are plain letters — this is a belt for
+ *    the suspenders).
+ *  - Whitespace runs collapse to a single space.
+ *  - A <br> sibling is a line break → emits a space.
+ *  - A line ending in "-" joins the next line WITHOUT the hyphen, so
+ *    "transport" matches a hyphenated "trans-\nport". The removed hyphen's
+ *    span characters become zero-width stops in the map so offsets after the
+ *    break still land on real text.
+ *
+ * No UI, no CSS Custom Highlight API — painting lives in
+ * pdf-find-highlight.ts. Pure functions so the whole module is unit-testable
+ * away from the viewer.

The card deferred the schema-v3 compiler stack fields twice ('not present
yet… added when those phases land'). That phase landed 2026-10-04 with the
compilation package's PRD #50 completion: system_hash (SHA-256 over the
device composite, loud mismatch on load), VerificationRecord (complete or
absent, trust ranking), hash/device-aware query with superseded-dropping
rank, provenance-gated bundled library.

The card now states the three-root truth: the fields' ground truth is the
compilation package's pulse-library module + the legato-dev skill; this
card's own vault-catalog + CLI surface remains Phase 0 (platform+gate
retrieval) with the CLI adoption tracked at harmoniqs/amicissimo#497; the
versioning/lineage conventions are unchanged. Sessions needing hash-exact
or verification-aware lookup are pointed at the compilation package's
query API until the CLI follow-up lands.

Finding: personal-vault skills-integrity finding-20261007-amico-catalog-phase0.
Lint: zero new findings against the main baseline.

+
+The compiler-stack fields phase landed 2026-10-04 with the compilation package's PRD #50 completion (harmoniqs/Legato.jl, main @ ee79bc4). Ground truth for field names, shapes, and semantics is that package's pulse-library module and the `legato-dev` skill (team vault), not this card:
+
+- **`system_hash`** — SHA-256 over the device composite (name, per-qubit ω/δ/levels, couplings, drive bound); performance metadata (T1/T2) is hash-excluded. A hash mismatch on load throws — device drift invalidates stale entries loudly.
+- **`VerificationRecord`** — solver fidelity + independent rollout fidelity + verifier + verified date; complete or absent, never partial. An entry is *verified* only when the record is present; trust ranking puts verified above unverified at equal fidelity.
+- **Query/ranking** — filters by platform, gate, device id, system hash (exact-hash option); superseded versions drop from ranking unless requested.
+- **Ingestion** — provenance per block (git commit, source script); the bundled public library is IP-gated by a device-profile allowlist.
+
+Phase 0 of THIS card's surface (the vault catalog + `amico catalog` CLI) does not implement these yet: retrieval remains by platform+gate only. The CLI follow-up (schema-v3 fields in query/ingest, verification-aware ranking) is tracked at **harmoniqs/amicissimo#497**. Until it lands, a session needing hash-exact or verification-aware lookup should use the compilation package's query API directly.

+// Admission goldens (amicode#1743, spec-20261008-054129 §D4/B1) — the resolved
+// + STAGED skill SET across entitlement and mount regimes, pinned as a golden.
+//
+// The suite is hermetic by construction: every library root, skill folder, and
+// entitlement list is a SYNTHETIC fixture under a temp dir — no chat-DB, no
+// live-machine paths, no vault mounts. The golden file (golden/admission_regimes.json)
+// pins the EXPECTED staged set per regime; the fixture here builds the INPUT
+// state; the REAL admission code under test (resolveLibrarySkillsWithProvenance
+// → stageOpencodeSkills — the exact seam session prep drives) maps between
+// them. A golden that re-implemented admission would test itself; this one
+// calls the product.
+//
+// Regimes (issue #1743 AC1): public-only (no entitlements, no vault mount),
+// entitled (entitled-surface skills present when the code is held), internal
+// mount present (all internal-surface skills stage), internal mount absent
+// (none stage, no crash). Leak pins (AC2/AC3): an entitled skill NEVER stages
+// without its entitlement; an internal-surface skill NEVER stages without the
+// mount (or from a root that does not admit internal). The least-privilege
+// invariant (AC4): a process-internal skill (surface: internal, sitting in
+// the public-shaped shipped library) never stages on any session surface.
+//
+// Goldens assert the SET (names + admission properties), never file contents
+// — content linting stays the nightly freshness check's job.

+// against the HUB's staging output.
+//
+// The hub's staging set builder is ops/server/stage-internal-skills.sh — a
+// shell script with NO importable seam (its only configurability is $HOME;
+// the armonissima vault root and the staged opencode-project tree are both

+// synthetic HOME: fixture vault, fixture staged tree, nothing from the live
+// machine. We assert the script's declared inputs/outputs — we never
+// re-implement its allowlist logic in a fixture.
+//
+// What this pins (the hub direction of the issue's admission contract):
+//  - internal mount present: exactly the ALLOWLISTED vault skills stage
+//    (the allowlist is the hub's admission gate — more restrictive than the
+//    client, which is the drift the issue records; pinned as-is, the
+//    manifest workstream (A2) owns changing it);
+//  - LEAK PIN: a vault skill NOT on the allowlist never stages, however
+//    much it exists in the mount;

Enumerate every webview registration under src/ through the TypeScript AST
(the createWebviewPanel / registerWebviewViewProvider call sites plus
.webview.options assignments) and assert retainContextWhenHidden: true on
each — or an explicit retain-exempt reason at the registration site (#1747).

The golden went red on enumeration exactly as it should have: fleet_panel and
onboarding_panel register webview panels with NO retention flag and no
exemption (the issue's three known panels were all correct). Per the AC's
exemption path and this slice's assertions-only constraint, both record
explicit retain-exempt reasons (on-demand report / one-shot walkthrough —
no live stream, onDidDispose + re-open rebuilds from scratch). The
fleet/onboarding flag decision belongs to the lane owner, not this slice.

The golden snapshot pins the enumerated set so the enumeration itself stays
alive; the invariants apply to whatever enumerates out, so a new panel is
covered the moment it appears in src/.

Three synthetic fixture cases prove the invariant checker is not vacuous:
a registration without the flag and without an exemption fails red (the
leak direction the golden demonstrated for real against fleet_panel and
onboarding_panel on its first run); retain-exempt with no stated reason is
still a violation — exemptions are never silent; and a properly flagged
registration (panel and webview-view shapes) is not a violation, so the
detector is not a blanket flagger.

develop: a Cast-deaths paragraph (the empty return is a cast death —
verify from artifacts, record, recast; finding F33) and a Standing-
directives section (a standing AFK mandate is the arc's explicit
approval within its named scope; outward acts always need the word;
finding F34 — the Favo PARKED-registration worked example).

write-an-issue: a standing-directive bullet in the approval gate
pointing at develop's section.

+### Cast deaths (the empty return)
+
+A cast that returns **empty** — state `completed`, zero output: no commits, no structured return — is a **cast death**, not an outcome. The empty return carries no information, including about the brief: verify from the worktree artifacts (commits, status, file mtimes), record the death in the ledger with that evidence, and recast the same brief. Three observed instances in one campaign all succeeded first-try on the recast — the brief was not the cause (finding F33).
+
 ## Terminal state per unit
 
 - **AFK** parent → the ready PR auto-merges (gated on CI where the repo has it); the parent issue closes on merge → the board's "Item closed" workflow moves its card to **Done** (never set manually).
 - **HITL** parent → the ready PR requests review and stops (no merge) → set the parent's board card to **In Review** as the final step, then verify it held and re-set if the board's async "PR linked → In Progress" workflow clobbered it (see `write-an-issue` 7e).
 
+### Standing directives (AFK mandates)
+
+A standing directive recorded in the ledger (the user's words + date — "do it all", "keep going for a while") is the explicit approval for the arc's issue filings AND its merge ladder, within the scope the directive names; every filing and every merge under it is reported in the loop record and the session summary. The mandate does not extend past its named scope: outward-publishing acts (releases, registration, visibility flips) always need the word. Worked example: the Favo campaign merged twelve standard-tier issues under two AFK mandates while holding its General-registry trigger parked for the user's explicit word (finding F34).
+
 ## When NOT to use
 
 - To implement a **single** issue interactively/standalone → use `/implement-issue` directly (this skill is for autonomous, possibly multi-unit, DAG execution).

+## Spec-design checks critics keep finding
+
+These came up repeatedly in one research campaign's critic rounds (the qpilc open-problems campaign, 2026-10). Each would have produced a wrong or pre-determined result. Run them yourself before the critics do:
+
+- **Pre-evaluate every trigger at the spec's own predicted effect size, in both directions.** Ask "can this condition fire?" and "can it fail to fire?" A bias trigger on a statistic that grows as √N, set at 3, fired by construction at the spec's own predicted shift. A sign-of-median trigger with |median| ≪ the per-seed SD is a coin flip. A materiality bar on the wrong statistic (a unitary distance, rather than the fidelity-ranking error the loop actually uses) nearly read "moot" where the loop-relevant quantity read "material". A trigger built never to fire is as uninformative as one built always to fire.
+- **Close every inaction route.** For each outcome, ask whether doing nothing (an always-reject gate, a never-firing gate, a near-zero step) can reach it. Do-nothing scored "regularization confirms" on a draw-free quality metric, a never-firing gate scored "safe", and a Euclidean motion floor admitted a placebo whose steps were J-invisible. Put a floor on benefit (a minimum median effect, not just a sign count) and match placebos in the measurement row space, not in Euclidean norm.
+- **Measure harness floors before pinning tolerances.** Weld, unitarity and identity tolerances must cite a measured dry-run floor of the exact code path, scaled with depth or steps where the error accumulates. Critics' estimates were wrong by 10–30× three times; each cost a pre-data amendment.
+- **Review the physics of every cited construction.** "[CITED] verbatim, hash-pinned" is provenance, not physics. For any truncated or extended Hilbert space, tabulate every operator element linking computational to non-computational levels and state its physical origin. Assert the symmetries the physical operator obeys: number conservation, total spin, ±1 readout spectra, time reversal. Run the factorization test: if the extra levels couple identically to every computational state, the channel must vanish. Treat any probe or log prose that names a modelling choice as the mechanism ("valley-agnostic", "effective", "truncated") as a blocking question.
+- **Put every verdict-moving choice in `acceptance`.** The review tool's design hash covers acceptance and budget only, so thresholds, grids, operator choices and the reading rule placed in prose invariants are unhashed. Paste constants under a weld tolerance at full precision with their file:row source, never rounded by hand.
+- **Make the outcome partition exhaustive and disjoint, and don't let a tie hand the label to one side.** If "X out-tracks Y" and "X ties Y" can both hold, the partition is broken. If the label rests on a precedence tie-break, report the robust ordering and the knife-edge seeds beside it.

+The knobs merged since 2026-10-26 (Intonatissimo `main` @ `29a4c91`; docstring
+`src/strategies/qp_ilc_strategy.jl:26-195`):
+
+- **`jacobian`** — `ModelJacobian()` (default; per-interval AD on the nominal or
+  recalibrated system), **`AnalyticJacobian()`** (#117, opt-in), `OpenSystemJacobian`
+  (Lindblad FD), `InjectedJacobian` (empirical G). `AnalyticJacobian` differentiates the
+  SAME discrete map as the AD source (midpoint substeps, the pulse's own interpolation)
+  by exact eigen-exponentials and Daleckii–Krein divided differences — agrees with AD to
+  its Taylor error (≲ 1e-12 relative on the campaign fixtures). It supports
+  `ZeroOrderPulse` (one exact exponential per interval), `LinearSplinePulse` and
+  `CubicSplinePulse` on **Hermitian, time-independent systems affine in the controls**
+  (ket and stacked multi-ket); anything else falls back to the AD source with a one-time
+  warning. It changes only G — the F-model diagnostic keeps the default Taylor rollout
+  (`src/optimizers/analytic_jacobian.jl:33-77`).
+- **`qp_backend`** — `:clarabel` (default), `:osqp`, or **`:lowrank`** (#115, opt-in): one
+  thin SVD of $G_w$, the Hessian held exactly as $\alpha I + V D V^\top$ with the same
+  robust-mode rank cut, pinned variables eliminated, bounds satisfied exactly, never an
+  $n \times n$ matrix (≫ 50× faster than Clarabel on the 1206-DOF Rydberg shape —
+  the Intonatissimo repo's 2026-10-27 low-rank QP benchmark note, #113). The #64 ensemble
+  normal equations and the #66 `dt_dof` column are not identity-plus-low-rank and fall
+  back to `:clarabel` with a one-time warning. Telemetry: `last_qp_backend`,
+  `last_qp_iterations`, `last_qp_status`. Its solution tolerance is ~1e-8 — don't write
+  equivalence clauses tighter than that (H27: a 1e-10 clause sat 3 decades below it).
+- **`robust_mode`** (default `false`) — adds $\lambda\|P_\text{null}\delta\|^2$,
+  $P_\text{null} = I - G_w^+ G_w$: penalizes J-invisible displacement (the E11 plateau fix).
+  `robust_lambda` (default `1e-2`) is read per **`robust_lambda_mode`**: `:absolute`
+  (default, prior numerics) or `:relative`, $\lambda_\text{eff} = $ `robust_lambda` ·
+  $\sigma_\max(G_w)^2$ recomputed each step (telemetry `last_robust_lambda_eff`).
+- **`robust_rtol`** (#110) — the singular-value cut of the projector. `nothing` (default)
+  now means **`1e-8` under `robust_mode`** (`DEFAULT_ROBUST_RTOL`, `:23`); the old
+  `pinv` cut (`eps·min(m, n)`) counted round-off modes as range and let the rank flip
+  across iterations, so $I - G^+G$ stopped being a projector and the QP failed. Spell the
+  old cut explicitly (`robust_rtol = eps(Float64) * min(size(Gw)...)`) only to reproduce
+  pre-#110 runs. Telemetry `last_robust_rtol`. Also from #110: a pulse whose interior knot
+  sits beyond the trust-box half-width outside its drive bound is clipped into bounds and
+  re-linearized instead of asserting (`last_restored_to_bound`, `restored_to_bound_count`).
+- **`last_linearization`** (#114, read-only) — after a successful step, that step's
+  `(; Gw, rw, δ_lo, δ_hi)` (with the δT column under `dt_dof`), `==` a fresh
+  linearization at the same inputs, so analysis code need not re-assemble G; `nothing`
+  before the first step and after a failed QP. #114 also made the ZOH Jacobian hot paths
+  fast and bit-identical (substep-exp hoist, F-model rollout reuse, threaded intervals).
+- **Pulse bases** — the QP proposes in the pulse's native space: ZOH and linear knot
+  values, cubic `[u; du]` (`du_frac` scales the tangent box); candidates are rebuilt in
+  the same type (a ZOH stays a `ZeroOrderPulse`, `src/optimizers/qp_inner_solver.jl:814-830`).
+  Design the pulse in its platform basis (PWL for AHS atoms, cubic elsewhere — ZOH is a
+  playback property); the QP inherits it. #116 also replaced the fixed-order Taylor
+  exponential with a norm-scaled one. Main's tests are re-paired to Piccolo #377's basis
+  guards (#119) — on a Piccolo with #377, the nominal `qcp` must pass its pairing check.
+- `ridge` is numerical damping, **not** a step-size control; the box radius
+  (`tr_frac`, `tr_mode = :range | :gain`) is the knob.
+
+**Production guidance (Rydberg persistent-drift fixture, H25 16 seeds / H27 32 seeds × 3
+parameterizations; qpilc campaign ledger, personal vault):**
+
+- For the full (unrestricted) QP use **`robust_mode = true`, `robust_lambda_mode =
+  :relative`, `robust_lambda = 1e2`, `robust_rtol` default** ("FR_prod"). H25: 0 QP
+  failures (the old pinv cut failed 17/192 rounds at the same λ — the rtol default, not
+  the dose, removes them), non-inferior to the labelled restricted step, dose-insensitive
+  over c ∈ {10, 100, 1000}. H27: FR_prod beat the unpenalized full QP at every
+  parameterization (PWL13 25/32, PWL25 31/32, ZOH201 30/32 seeds).
+- **Size expectations honestly:** the out-of-sample benefit vs doing nothing is small and
+  seed-dependent (ZOH201 median 1.2e-4 at 32 seeds; H25's 6.08e-4 was an upper-tail draw).
+  Read seed-paired contrasts, never absolute benefit at n ≈ 16.
+- **The refit is the lever, not the step.** The per-seed losers are drift below the
+  per-step cost and in-loop **refit runaways** (Spearman −0.63…−0.73 at ZOH), not step
+  representation. rank($G_w$) = 5 at every parameterization tried (gate + 45-row readout
+  physics), so a readout null space exists regardless of knot count; the next work is a
+  prior-anchored / bounded refit (campaign R2 H26).
+- At too few design columns the penalty costs **reach** (PWL13: ‖G_w δ‖ 0.50× the
+  unpenalized step at 33 free columns) — check reach before adopting a coarse design.

Subject: [PATCH 44/80] feat(session-ui): add Cmd+L (Mod-l) go-to-line shortcut
 in CM6 editors

Binds Mod-l to CM6's gotoLine command in baseExtensions(), following the
Overleaf/Sublime/Atom convention. The existing Cmd+Alt+G binding from
searchKeymap is preserved unchanged.

The keymap array is extracted into a new exported keymapBindings() helper
so tests can assert specific bindings without coupling to CM6 internals.

Subject: [PATCH 45/80] fix(app): refocus composer and restore caret on session
 tab switch
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Clicking a session tab moved focus to the tab button; the composer
lost keyboard focus and the caret jumped to end on every switch.

Changes in session.tsx (overlay):
- Import getCursorPosition alongside the existing setCursorPosition.
- Add sessionCaretOffsets (Map<sessionKey, number>) to persist the
  caret offset while the user is typing in a given session.
- On mount, attach a document selectionchange listener that records
  getCursorPosition(inputRef) for the current session key whenever
  the composer editor owns the active selection.
- Add a createEffect on sessionKey (defer) that, on every tab switch
  between real sessions, rAF-defers focus + setCursorPosition to the
  saved offset (fallback: prompt.cursor(), then end-of-content).
  Guards: skips draft→session and child sessions (already blocked).

Subject: [PATCH 46/80] test: #1790 AC1/AC2/AC3 pinning tests for the three
 remaining SSE stream readers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Three readers still used the quadratic buf.indexOf pattern after #1779:
- OpencodeEventClient.onChunk (sse_client.ts)
- SessionMultiplexProxy.openSseStream (session_multiplexer.ts)
- SessionStreamFilter.push (session_event_resume.ts)

Pin the three acceptance criteria:
  AC1 — each reader splits a 10 MB frame in 64 KB chunks within 3× of
         the one-chunk baseline (timing via SseFrameSplitter as the
         reference target for the mux and client, and directly for the
         filter).
  AC2 — each reader ends a frame at a CRLF blank line, including a
         boundary (\r\n\r | \n) that straddles two chunks.
  AC3 — framing unchanged: multi-line data, ids, retry, event names —
         byte-identical at every byte-offset cut.

Tests run RED before the fix (CRLF tests fail for the client and mux;
SessionStreamFilter timing fails with the old quadratic path).

+// linear_sse_frame_splitting_1790.test.ts — #1790: linear-time SSE frame
+// splitting in the three remaining stream readers.
+//
+// The relay's upstream reader and the app's global-stream reader were fixed in
+// #1779.  Three readers were left behind:
+//   1. OpencodeEventClient.onChunk (sse_client.ts) — appends chunk to `this.buf`
+//      and calls `this.buf.indexOf("\n\n")` from the start on every chunk.
+//   2. SessionMultiplexProxy.openSseStream (session_multiplexer.ts) — same
+//      `buf += chunk; buf.indexOf("\n\n")` pattern in the peer event-stream reader.
+//   3. SessionStreamFilter.push (session_event_resume.ts) — uses `boundaryEnd()`
+//      which also calls `s.indexOf("\n\n")` and `s.indexOf("\r\n\r\n")` on the
+//      full accumulated partial buffer.
+//
+// All three miss the `\r\n\r\n` SSE frame boundary too (only detect `\n\n`).
+//
+// AC1 — each reader splits a 10 MB frame in 64 KB chunks within 3× of the time
+//        for the same frame delivered as one chunk.
+// AC2 — each reader ends a frame at a CRLF blank line, including a boundary that
+//        straddles two chunks.
+// AC3 — framing otherwise unchanged: multi-line data, event names, ids, retry —
+//        byte-identical, with the input cut at every byte offset.

Subject: [PATCH 47/80] perf(fleet): linear-time SSE frame splitting in the
 three remaining readers (#1790)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The relay's upstream reader and the app's global-stream reader were made
O(chunk) in #1779.  Three readers were left with the quadratic
  buf += chunk; buf.indexOf("\n\n")
pattern that re-scans the whole accumulated partial buffer on every
incoming network chunk.  For a 10 MB frame arriving in ~160 × 64 KB
chunks that costs ~160 full-buffer scans.

Fix the three readers:

**SessionStreamFilter (session_event_resume.ts)**
  Replace the string-accumulation + boundaryEnd() loop with a byte-level
  scanner that walks only the new chunk, carrying a two-byte lookback for
  a frame boundary (\n\n or \r\n\r\n) split across chunks.  The
  filter now operates on raw Buffer inputs natively — no intermediate
  string join while the frame grows — and joins the accumulated Buffer
  parts exactly once when the frame completes (held as pieces, identical
  to the SseFrameSplitter design from #1779).

**OpencodeEventClient (sse_client.ts)**
  Replace the private buf string + indexOf loop with SseFrameSplitter.
  The splitter is reset on each new connection so a partial frame from
  a previous connection never bleeds into the reconnect.  handleBlock
  also updated to split on /\r?\n/ so CRLF fields inside a frame are
  handled correctly.

**SessionMultiplexProxy.openSseStream (session_multiplexer.ts)**
  Replace the local buf string + indexOf loop with SseFrameSplitter.
  SseFrameSplitter handles both LF and CRLF frame endings and scans
  only the new decoded text chunk.

All three readers now:
  — split a 10 MB frame delivered in 64 KB chunks within 3× of the
    same frame delivered as one chunk (AC1 — #1779-class measurement);
  — end a frame at a CRLF blank line (\r\n\r\n), including a
    boundary that straddles two chunks (AC2);
  — produce byte-identical output at every byte-offset cut (AC3).

Subject: [PATCH 48/80] fix(test): surface engine log on session-create
 timeout; 120s cold-start budget (#1796)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The mode_block session-API fixture's first POST /session can hit a
timeout on cold CI runners because the engine's instance cold-start
(plugin factory + background package install into the test's empty
HOME) happens inside that call.  Two fixes:

(a) LOG — wrap the fetch in a try/catch using a manual AbortController
    so any timeout or network error throws with the engine's captured
    stdout/stderr included in the message.  Previously AbortSignal
    .timeout() threw a bare DOMException with no context, making a
    slow install indistinguishable from a hung startup.

(b) COLD-START OUT — increase the session-create budget from 60 s
    to 120 s and frame the step as the pre-warm phase; the cold-start
    cost now sits here rather than competing with the fixture's
    assertion windows.  The warm path (packages already installed)
    stays at 8–13 s.

Fixes harmoniqs/amicode#1796 AC1 (engine log on timeout).
AC2 (20 consecutive CI runs) relies on the 120 s budget being
sufficient for cold CI runners.

Subject: [PATCH 49/80] fix(onboarding): drop profileHasIdentity() gate from
 shouldOnboard (#1161)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The completion marker (~/.amico/amicode/onboarding/completed) is the
sole signal that onboarding is done. Identity fields written by the
About You settings card (name, affiliation, etc.) in profile.json are
NOT a completion signal — the interview's own resume logic merges
partial profile state. Removing !profileHasIdentity() from shouldOnboard
fixes the bug where a user with any saved identity fields got a blank
session instead of the onboarding interview.

profileHasIdentity() is preserved as an exported function (unit-tested
independently) but is no longer part of the routing predicate.

Tests: extend overture_routing with two new cases:
- identity in profile.json + no completion marker → overture (was failing)
- identity in profile.json + completion marker present → pulse-designer

Subject: [PATCH 53/80] feat(chat): inline previews for agent-written images,
 with copy to the user's clipboard
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Markdown images with an absolute server path load through /file/content and
render framed in chat; click opens a full-size preview, and the hover/preview
Copy action writes a PNG to the OS clipboard via a new clipboard-image-write
bridge kind handled by the extension host (osascript / xclip / wl-copy) — on
the machine the user is at, not the server.

Subject: [PATCH 56/80] feat(session-ui): syntax-aware code folding in CM6
 editors (harmoniqs/amicode#1517)

Wire foldGutter() and foldKeymap into baseExtensions(), add explicit
Mod-Shift-[ / Mod-Shift-] fold/unfold bindings (foldKeymap uses Cmd-Alt on
mac), style the fold gutter with the existing v2 tokens, and cover it with
tests. Manifest hashes refreshed for the overlay edit.

+ * dialog, or while focus sits inside `[data-prevent-autofocus]` or in another
+ * text-entry surface (the terminal's xterm textarea, a CM6 editor, any input).
+ * Unlike type-to-focus, a focused BUTTON does not block: the tab the user just
+ * clicked is a button, and taking focus off it is the point.

+      The picker now probes your connected providers and hides models your

+      Overnight runs now check their work against the same cheap gates CI
+      runs (drift, typecheck, the tests the change touched) before opening a

+      The hub's frontdoor now binds to 127.0.0.1 and is reached through the

647-line patch keyed to sdk@1.29.0 (session-expiry re-init, typed callTool
overloads, determineScope/offline_access, isRequestActive). A 1.32.2 pin
silently drops it and reds the engine typecheck gate (catalog.ts, code-mode.ts,
oauth-provider.test.ts). Escalated rather than ported.

-  the measurement cannot see (often saturating the trust box), and that content costs true fidelity.
-  `QPILCStrategy(; robust_mode = true, robust_lambda_mode = :relative, robust_lambda = 100)` penalizes
-  exactly that (λ_eff = 100·σ_max(Gw)², recomputed per step). Leave `robust_rtol` at its `robust_mode`
-  default of 1e-8. At pinv's default cut, round-off singular values enter the projector, the QP matrix
-  becomes indefinite, and the solver fails on some rounds (measured at the same λ: 17 of 192 rounds failed
-  at the old cut, 0 of 768 at 1e-8). The dose is not sensitive: c = 10, 100 and 1000 performed within
-  noise of each other. What has been measured for this exact configuration: at a Rydberg fixture under
-  persistent drift (16 seeds) it never failed, was within 5e-4 of a hand-labelled K=2 basis at 90%
-  confidence, and beat the unrestricted step on 14 of 16 seeds. A fixed-λ version of the same penalty tied
-  a hand-built K=4 basis at a transmon fixture. Both results needed no labels and stayed within the drive

 Amicode talks to Slack through the [`slack-mcp-server`](https://github.com/korotovsky/slack-mcp-server) MCP package. Messages are sent **as you** (user OAuth token), not as a bot. The integration is outbound-only — Amicode calls the Slack Web API when you ask it to; there are no inbound webhooks or event subscriptions.

 3. Register the localhost redirect URI (for `amico slack login`)

 ## Prerequisites
 
@@ -33,24 +34,23 @@ The manifest defines a minimal Slack app with:
 | Section | What it does |
 |---------|-------------|
 | `bot_user` | Required by Slack's OAuth install flow — sits idle; you use the user token |
-| `bot` scopes | Valid bot-token scopes (everything except `search:read`, which is user-only) |
-| `user` scopes | The real permissions — read history, list channels/DMs, post messages, search, resolve users |
+| `bot` scopes | Read-side bot-token scopes plus `chat:write`, so the idle bot user can install (never `search:read`, which is user-only) |
+| `user` scopes | The real permissions — read history, list channels/DMs, open DMs and group DMs, post messages, search, resolve users. They match the `USER_SCOPES` that `amico slack login` requests |
 | `socket_mode_enabled: false` | No inbound event delivery needed |
 | `is_hosted: false` | Not a Slack-hosted app |
 
 **Why both bot and user scopes?**
-Slack won't complete the OAuth install without a bot user, and a bot user needs at least one scope. The bot scopes mirror the user scopes minus `search:read` (which isn't valid for bot tokens — putting it there causes validation errors in Slack's manifest editor). In practice, Amicode only uses the **User OAuth Token** (`xoxp-…`).
+Slack won't complete the OAuth install without a bot user, and a bot user needs at least one scope. The bot scopes are the user scopes minus `search:read` (which isn't valid for bot tokens — putting it there causes validation errors in Slack's manifest editor) and minus the DM-opening `im:write` / `mpim:write`, which only the user token needs. In practice, Amicode only uses the **User OAuth Token** (`xoxp-…`).
 
 **Why `search:read` is user-only:**
 Slack's API restricts `search:read` to user tokens. If you add it under `bot` scopes, the manifest editor shows red validation errors on every bot scope line and the install fails.
 
-## Step 2: Install and get the User OAuth Token
+## Step 2: Copy the app credentials
 
-1. After creating the app, click **Install to Workspace** and authorize
-2. Go to **App Settings** → **OAuth & Permissions**
-3. Copy the **User OAuth Token** (starts with `xoxp-`)
+1. In the app's settings, open **Basic Information** → **App Credentials**
+2. Copy the **Client ID** and the **Client Secret**
 
-You do **not** need the Bot Token (`xoxb-`) or App Token (`xapp-`) — those are for the idle bot user.
+Slack's `oauth.v2.access` exchange needs both, even under PKCE. You do **not** copy a token by hand: `amico slack login` (Step 4) obtains your User OAuth Token (`xoxp-…`) itself. You never need the Bot Token (`xoxb-`) or an App Token (`xapp-`) — those belong to the idle bot user.

 2. Click **Save URLs**
 
-> **Note:** The port (`54213`) may vary between login attempts. If you see a `redirect_uri did not match` error with a different port, add that port's callback URL as well.
-
-## Step 4: Wire the MCP server into Amicode
-
-Add a `slack` entry under `mcp` in your Amicode config (`~/.config/opencode/opencode.json`):
-
-```json
-{
-  "mcp": {
-    "slack": {
-      "type": "local",
-      "command": "npx",
-      "args": ["-y", "slack-mcp-server"],
-      "env": {
-        "SLACK_TOKEN": "<your xoxp- user OAuth token>"
-      }
-    }
-  }
-}
+> **Note:** The port is fixed at `54213`. If something else is listening on it, `amico slack login` reports that the port is in use; close the other process and retry.
+
+## Step 4: Give Amicode the app credentials, then log in
+
+`amico slack login` reads the app credentials from, in priority order:
+
+1. the environment — `AMICODE_SLACK_CLIENT_ID` and `AMICODE_SLACK_CLIENT_SECRET`, or
+2. `~/.amico/slack-app.json` — `{ "client_id": "…", "client_secret": "…" }` (mode 600). **Settings → Connections → Slack** in Amicode writes this file for you.
+
+Then run:
+
+```bash
+amico slack login
 ```
 
-Replace `<your xoxp- user OAuth token>` with the token from Step 2.
+It opens your browser at Slack's authorize page (PKCE, user scopes only). Approve it, and the callback on `http://localhost:54213/callback` exchanges the code for your User OAuth Token (`xoxp-…`) and writes it to `~/.amico/slack.json` (atomic, mode 600; `AMICO_SLACK_FILE` overrides the path). The flow times out after 120 seconds if no callback arrives.
 
-The MCP package is **`slack-mcp-server`** by korotovsky (not `@anthropic/slack-mcp-server`).
+You do not edit `opencode.json` or paste a token anywhere.
 
-## Step 5: Reload and verify
+## Step 5: Verify
 
-1. Reload the Amicode window: **Cmd+Shift+P** → **Developer: Reload Window**
-2. Open a **new chat session** (the + button)
-3. Ask Amico to send a test message, e.g.: *"message @someone in Slack saying hello"*
+1. Amicode watches `~/.amico/slack.json`. When the file appears, the extension adds the `slack` MCP server (`npx -y slack-mcp-server`, by korotovsky — not `@anthropic/slack-mcp-server`) to the running engine on its own. If that live add fails, it restarts the server instead. Deleting the file removes the server.
+2. Open a **new chat session** (the + button). Sessions that were already open do not pick up the new tools.
+3. Ask Amico to send a test message, for example: *"message @someone in Slack saying hello"*.
 
-If the MCP server loaded correctly, Amico will have access to tools like `users_search`, `conversations_add_message`, `conversations_history`, and `channels_list`.
