fix(ingest): route raw claude-session dumps to non-indexed archive, not wiki

claudeSink wrote every raw transcript into brain/wiki/claude-sessions/facts/
(BM25-indexed), duplicating what ai-sessions' curated summaries already
cover and out-ranking them in search (177,818 vs 45,335 BM25 weight on the
same query, per ai-sessions#10 investigation). Raw dumps now land in
brain/archive/claude-sessions/<host>/ — kept for deep lookups, never
indexed, never deleted.

+# Icebox — retired code (recoverable, not destroyed)
+
+Per issue #75 (consolidate to a single harness), the routing-pod path was removed
+from the live tree. It is **preserved and recoverable**, not deleted without trace.
+
+## What was iceboxed (2026-07-01, issue #75)
+
+| Path | Why |
+|------|-----|
+| `cmd/routing/` | The routing MCP-server binary; every skill call was wrapped through the broken pass-rate router (`wrap(skillName)`). |
+| `internal/routing/` | Router / Fetcher / Policy / pass-rate. Signal is survivorship-biased and unusable as-is (infra#174). |
+| `internal/skills/{review,debug,retrospective,trainer,project}/` | Skill handlers usable **only** through `cmd/routing` (verified: each imported solely by `cmd/routing`). |
+| `Dockerfile.routing` | Built `cmd/routing` exclusively. |
+| `.gitea/workflows/cd.yml` (routing steps only) | Removed the routing image build + infra image-bump + Flux-wait/rollout-verify for routing; **ingestion build/deploy is unchanged**. |
+
+## Why
+
+The live minimal harness is `cmd/hyperguild` + `brain-mcp` (+ `gitea-mcp` available) —
+that is what ran the infra#170 loop-1 experiment (routing/injection machinery off) and
+closed it twice. `cmd/hyperguild` has **zero** transitive dependency on `internal/routing`
+or `cmd/routing`'s packages (it imports only `internal/tier`). The routing pass-rate signal
+is being retired, not resurrected (fresh start, per infra#174).
+
+## How to recover
+
+Everything above is preserved at commit `00e5f62` under:
+
+- **tag** `icebox/cmd-routing-2026-07-01`
+- **branch** `icebox/cmd-routing`
+
+```bash
+# inspect
+git checkout icebox/cmd-routing-2026-07-01
+
+# restore specific packages onto a branch
+git checkout icebox/cmd-routing-2026-07-01 -- cmd/routing internal/routing \
+  internal/skills/review internal/skills/debug internal/skills/retrospective \
+  internal/skills/trainer internal/skills/project Dockerfile.routing
+```
+
+## Deliberately NOT touched here (separate scope)
+
+- **Live k8s routing deployment** (`infra` repo, `k3s/apps/routing/`) still runs its last
+  image; CD no longer rebuilds/redeploys it. Tearing down that deployment is a separate
+  infra-repo task.
+- **`internal/skills/{brain,org,sessionlog}/`** — kept per #75; already had no importer
+  (orphaned before this cut), harmless, compile + test green.
+- **`config/supervisor/{review,debug,retrospective,trainer-*}.md`** — routing skill prompts,
+  now orphaned data; left in place (not code, no build impact).

+# Runbook: exercising review/debug traffic to fill the pass-rate dataset
+
+**Why this exists:** the routing pod's local-vs-cloud decision is gated on a
+pass-rate history that only accrues from real `review`/`debug` invocations
+**through the pod**. Until the dataset has data, the fast (local) path never
+activates and the core hypothesis (hyperguild #35) can't be validated. This
+runbook is how you spin that flywheel.
+
+## The one trap
+
+Pass-rate accrues **only** when a skill tool is called via the routing pod's MCP
+endpoint. These look like they should count but **do not**:
+
+- **Crush** — talks to LiteLLM directly, bypasses the pod. No log.
+- **claude.ai web / Claude Desktop without the connector** — no log.
+- **Running the local `code-review` / `debug` skills** (`~/dev/.skills`) inline in
+  a Claude Code session — those are local skills, not the pod's MCP tools. No log.
+
+Only a `tools/call` to the routing pod records a pass/fail.
+
+## Endpoints
+
+| Purpose | URL | Auth |
+|---------|-----|------|
+| Routing MCP (local, Tailscale) | `http://koala:30310/mcp` | Bearer `ROUTING_MCP_TOKEN` |
+| Routing MCP (remote) | `https://routing-mcp.d-ma.be/mcp` | OAuth via `auth.d-ma.be` (audience `claude-ai`) |
+| Pass-rate readout | `http://koala:30330/pass-rate?skill=<name>` | none (read-only) |
+
+Tools advertised: **`review`**, **`debug`** (the two the #35 gate measures),
+plus `session_log`, `retrospective`, `trainer`.
+
+## Step 1 — connect the routing pod as an MCP server
+
+**Local** (needs the bearer token; keep it out of argv via 1Password):
+
+```bash
+op run --env-file ~/.op-env -- \
+  claude mcp add routing --transport http http://koala:30310/mcp \
+    --header "Authorization: Bearer $ROUTING_MCP_TOKEN"
+```
+
+**Remote** (claude.ai / Claude Desktop): add a custom connector pointing at
+`https://routing-mcp.d-ma.be/mcp`; it completes OAuth against `auth.d-ma.be`,
+no static token.
+
+Verify: a `tools/list` should return `review`, `debug`, `session_log`,
+`retrospective`, `trainer`.
+
+## Step 2 — route real work through it
+
+In normal sessions, invoke the pod's tools instead of reviewing/debugging inline:
+
+- *"Use the **routing** `review` tool on this diff."*
+- *"**debug** this failure through the routing pod."*
+
+Each call logs an outcome to ingestion → `/pass-rate` ticks up.
+
+## Step 3 — how routing actually picks the model
+
+Per `internal/routing/policy.go`:
+
+1. pass-rate `nil` (cold) → **local** fast tier. The router defaults to local
+   from invocation #1, not to cloud — so the fast tier is exercised immediately.
+2. pass-rate `>= 0.90` (floor) → **local**; `< 0.70` (ceil) → **cloud/thinking**;
+   in the `[0.70, 0.90)` band a request-hash bit samples 50/50.
+3. On a local execution error the router falls open to the thinking model for
+   that one call (logged `thinking_fallback`).
+
+So you are not "paying in on cloud" — cold calls already run on the (validated)
+local fast tier **`koala/qwen36-35b-a3b`** (Qwen3.6-35B-A3B MTP, promoted
+2026-06-29, infra `c66a195`, `HYPERGUILD_FAST_MODEL`). Accumulating passes just
+keeps it there once real pass-rate is computed.
+
+> **Instrumentation note (#73, fixed 2026-06-30):** until v0.11.1 the pod logged
+> successes as `"skip"` (not `"pass"`), under `skill:"_routing"`, via an
+> unauthenticated POST that silently 401'd — so `/pass-rate` stayed at zero no
+> matter how much you used it. That's fixed and verified (a real review call now
+> moves `/pass-rate?skill=review` 0→1). If you see traffic not registering,
+> re-check #73's three failure modes first.
+
+## Target & verification
+
+- **50 logged invocations** across `review` + `debug` within the 14-day window.
+  The clock restarts **2026-06-30** (the day instrumentation was verified working;
+  the original 2026-06-26→07-10 window measured broken plumbing) → **kill-date
+  2026-07-14**, ~4 calls/day (1 already logged from the #73 smoke test).
+- Check progress anytime:
+
+  ```bash
+  curl -s "http://koala:30330/pass-rate?skill=review"
+  curl -s "http://koala:30330/pass-rate?skill=debug"
+  ```
+
+- If ~4–5/day isn't realistic alongside Crush, that is **not** a failure — per
+  #35 deliverable #1 it's the signal hyperguild isn't on the work critical path,
+  and the pre-decided **Berget fallback** (`gpt-oss-120b` / `qwen3-32b`) carries
+  the fast tier instead.

 - **Ground-truth at HEAD before acting.** Issue bodies and doc references rot — stale hostnames, retired services, moved endpoints. Before closing/commenting on any issue, `gitea:issue_get` it fresh. Before asserting an infra fact, verify it; do not copy it from memory or from a stale issue body.
 - **Current infra truths** (verify rather than trust, but these are the known-good baseline): Gitea is `git.d-ma.be` (not `gitea.d-ma.be`). LiteLLM is `http://koala:30401/v1/` (public `https://llm-api.d-ma.be`); piguard runs NGINX Proxy Manager only — never reference `piguard:4000` or `koala:4000`.

-**GATE — STOP and get explicit confirmation before any issue write.** Issue closes and new issues are side-effects. Once confirmed, execute them (`gitea:issue_close`, `gitea:issue_create`, `gitea:issue_comment`, all owner `mathias`), correcting any rotted references you found in Phase 2 as you go.
+These actions are **carried into the Phase 4 capture call** as `tickets[]` rather than executed here with direct `gitea:issue_*` calls — routing them through capture puts each one into the I5 audit record. (Closing an issue that needs a separate explanatory comment first is the one case to do directly; otherwise prefer the capture path.)
 
-## Phase 4 — Commit the canonical session summary
+## Phase 4 — Capture (one uniform call)
 
-Write one summary file to `mathias/ai-sessions`, committed directly to `main` via `gitea:file_write_branch` (no PR — this repo is solo and unprotected; if branch protection is ever added, fall back to a branch + PR).
+Persist the session via a **single `capture` call** (the `brain:capture` MCP tool, live on the Claude.ai connector). Capture owns the writes server-side — insights → brain, action items → Gitea tickets, summary → ai-sessions — plus the I1 sovereignty gate, the I5 audit record, and the supersession/read-after-write discipline. The skill's job is to *assemble the payload*, not to write each store itself. Do NOT fall back to separate `gitea:file_write_branch` + `brain_write` steps unless `capture` is unreachable (see fallback below).
 
-**Path:** `summaries/claudeai/<YYYY-MM>/<YYYY-MM-DD>-<topic-slug>-<chatid8>.md`
-where `<chatid8>` is the first 8 chars of the chat's UUID if known, else a short stable slug. `claudeai` has no host segment — Claude.ai is Anthropic-side, not a homelab host.
+**Assemble one payload:**
 
-**Frontmatter — the REDUCED live-capture schema.** A live close-session capture cannot populate the batch-export telemetry (token counts, message counts, duration_ms, permission_mode) — those only exist in the account export pipeline. Write only what's truthfully known, and mark fidelity so a reader (or the batch pipeline) can tell a live capture from an export:
+- **`insights[]`** — the generalizable learnings from Phase 1 (decisions/failures worth re-reading). Each: `{text, wing, hall}`; add `supersede_slug` to revise a prior note in place instead of creating a duplicate. `hall` ∈ facts/decisions/failures/hypotheses/sources.
+- **`tickets[]`** — the issue actions from Phase 3: `{repo, action, ...}` where action ∈ create/close/comment. Owner is always `mathias` (server-forced).
+- **`summary`** — `{title, body, repos_touched}`. Capture writes it to `ai-sessions` and stamps `fidelity` in frontmatter. Body stays reconstructable: one-paragraph summary, decisions, key artifacts, open threads.
+- **`context`** — `{harness: "claudeai-chat", session_ref: <chatid8-or-slug>, fidelity: "live-capture", actor: "mathias", classification: <see gate below>}`.
 
-```yaml
----
-title: "<concise session title>"
-client: "claudeai"
-interface: "claudeai-chat"
-date: "<YYYY-MM-DD>"
-repos_touched: [<repo slugs>]
-topic_tags: [<tags>]
-outcome: "<shipped|in-progress|abandoned>"
-fidelity: "live-capture"   # NOT an export; reconstructed live from chat
-captured_by: "close-session-skill"
----
-```
+**THE CLASSIFICATION GATE (read before calling — this is where capture refuses).**
+Capture computes an **effective classification = the strictest across EVERY target it touches** (each insight's `wing`, each ticket's `repo`, and every entry in `summary.repos_touched`), then refuses if that effective level is `confidential` and the origin is us-nexus (claude.ai is us-nexus). Levels come from `classification.yaml` at the brain root (source of truth, #67), with the code defaults as the floor: `hyperguild`/`homelab` → internal; `client-*` → confidential; **anything untagged → confidential (fail-safe)**.
+- **Tagged `internal` today** (safe through claude.ai): wings `hyperguild`, `homelab`; repos `brain`, `ai-sessions`, `infra`, `hyperguild`, `homelab`, `tapir`, `agentsquad`, `jepa-fx-risk`, `swedsl`. Treat `classification.yaml` as authoritative — this list is a hint, not gospel.
+- Declare `context.classification: "internal"` for normal homelab work.
+- `summary.repos_touched`, insight `wing`s, and ticket `repo`s are classification INPUTS, not free-form metadata — every target must resolve `internal` or the whole capture escalates to `confidential` and the gate refuses via claude.ai. Listing the central homelab repos (incl. `brain`/`ai-sessions`) is now fine; they're tagged. The summary always lands in `ai-sessions` (internal), so the summary path itself never escalates.
+- If a session genuinely touched **`client-*` or otherwise-untagged** material, it cannot be captured through claude.ai — note that in the verdict rather than trying to force it.
 
-Do not invent the export-only fields. `fidelity: live-capture` is the honest signal; if the batch export later produces a richer summary for the same session, the export is source of truth and supersedes this.
+**GATE — dry-run first, then execute.**
+1. Call `capture` with `dry_run: true`. It validates the whole payload and returns the would-be receipt + `effective_classification`, writing nothing.
+2. **STOP. Show the dry-run receipt** (effective classification, the insights/tickets/summary that would land) and get explicit confirmation.
+3. On confirmation, call `capture` again with `dry_run: false`. Read the returned receipt: it is partial-aware (`errors[]`, per-item `ok`). Report exactly what landed.
 
-**Body** (keep it reconstructable, not exhaustive):
-```markdown
-## One-paragraph summary
-## Decisions
-## Key artifacts
-## Open threads
-```
+If `capture` is **unreachable** (tool not on the connector — e.g. a session that started before a deploy; a tool-list refresh usually fixes it): say so. Only then fall back to the legacy inline path (`gitea:file_write_branch` summary + `brain_write`/`brain_update` + `brain_get` confirm), and note in the verdict that the I5 audit record was NOT produced.
 
-**GATE — STOP, show the full file (path + frontmatter + body), get explicit confirmation before committing.**
-
-## Phase 5 — Brain orientation note (the durable "where we are" record)
-
-Write one brain note so a fresh session can orient without the chat. This uses the `brain_update`/`brain_get` verbs (live since 2026-06).
-
-**Target:** `wing: <domain>` (the project/topic domain, e.g. `hyperguild`, `jepa-fx`), `hall: decisions`. The note is a knowledge-type record (a decision/orientation), grouped by knowledge-type, not by interface surface.
-
-**Batch read-after-write discipline (important — do these in order, do not interleave):**
-
-1. **Read first, before any write.** Check whether an orientation note already exists for this wing/topic. Do your "does this already exist / what should I supersede" reads NOW, up front. BM25/keyword search and `brain_get` are immediate; semantic/vector search may lag up to ~5 min after a write, so never rely on a semantic query to find something you wrote earlier in this same run.
-2. **Write or supersede:**
-   - **New note** → `brain_write` (wing, hall: decisions). Returns `{id, path, content_hash}`.
-   - **Superseding a prior orientation note** → `brain_update` (slug or path, wing, hall, content, reason). Whole-note replace; stamps `supersedes`/`updated_at`; returns `{id, path, content_hash, superseded}`. Use this instead of a second `brain_write` to the same slug — blind re-write creates duplicates/contradictions, which is the exact failure brain_update exists to prevent.
-3. **Confirm it landed** via `brain_get(id)` and check the returned `content_hash` matches what the write returned. This is the read-after-write confirmation — do it with `brain_get`, never a semantic query.
-
-**RULE: no semantic/vector brain query after the first `brain_update` in this run.** The batch shape makes this natural — read up front, write, confirm by id. If you ever find the skill wanting to semantic-search a just-superseded note, stop and flag it (that's the signal the staleness window matters and needs the synchronous-reembed follow-up).
-
-**GATE — STOP, show the note (target wing/hall, new-vs-supersede, full content), get explicit confirmation before the brain write.**
-
-After the note lands, if it relates to a note in another wing, create the cross-link inline with `brain_tunnel(source, target)` (idempotent; both paths brain-relative, must be in different wings). Optionally append a `session_log` entry (`session_id`, `skill: close-session`, `phase`, `final_status`) for telemetry. Both are now callable directly from Claude.ai — no Claude Code/Crush handoff needed.
-
-## Phase 6 — Verdict
+## Phase 5 — Verdict
 
 Deliver a final "safe to archive" verdict in the chat. Either:
 
-- **SAFE TO ARCHIVE** — list what landed (issues closed/filed with numbers, summary path, brain note id, any tunnels) so the trail is auditable. Then list anything still in the user's queue (e.g. a PR awaiting their merge, a decision owed next session).
-- **NOT YET** — name the specific gate that wasn't passed or the write that failed, and what to do about it.
+- **SAFE TO ARCHIVE** — list what landed from the capture receipt (issues closed/filed with numbers, summary path, brain note ids/paths) so the trail is auditable. Then list anything still in the user's queue (e.g. a PR awaiting their merge, a decision owed next session).
+- **NOT YET** — name the specific gate that wasn't passed, the capture refusal reason, or the per-item error from the receipt, and what to do about it.
 
-Never claim safe-to-archive if any gated write was declined or errored. The verdict is the skill's contract: if it says safe, the session can be lost without losing the work.

-## Why the gates and the batch discipline matter
+## Why the gate and the single-call shape matter
 
-The whole point is durability across a context reset. Every gate is a place where a wrong write would silently corrupt the record (close the wrong issue, overwrite a good brain note, commit a half-truth). The batch read-discipline in Phase 5 exists because the brain's vector index refreshes out-of-band: write-then-semantically-reread in the same run can read stale, so the skill front-loads reads and confirms writes by id. Get those right and the skill does what it promises — nothing important is lost when the chat goes away.
+The whole point is durability across a context reset. The capture call is the one place a wrong payload would silently corrupt the record (close the wrong issue, escalate to a refusal, commit a half-truth), which is why it is dry-run-then-confirm. Routing everything through one `capture` keeps the supersession discipline, the read-after-write confirmation, and the I5 audit trail server-side — the skill never has to carry those rules itself, and every closeout is uniformly audited. Get the payload and the classification right and the skill does what it promises — nothing important is lost when the chat goes away.

+# Capture capability — implementation report (as-built)
+
+**Status:** Shipped 2026-06-23, tagged `v0.11.0`. Epic hyperguild #49 (sub-issues #50–#55) closed.
+**Spec:** `specs/capture-bdd-spec.md` (the design contract this implements).
+**Governed by:** `infra/docs/architecture/01-invariants.md` (I1–I5) + the I2 acceptance ledger entry in `infra/docs/security-baseline.md`.
+
+This document records what was actually built, where it lives, how it maps to the spec, and what was deferred — for onboarding and future audit. It does not restate the design rationale (see the spec and the linked brain entries).
+
+---
+
+## 1. Outcome
+
+One uniform capture capability — insights → brain, action items → Gitea tickets, optional summary → ai-sessions — reachable identically from every harness:
+
+- **In-process / direct-REST harnesses** (Claude Code CLI, Agentsquad, claude.ai Code, headless): `POST /capture` on the brain server.
+- **MCP-native harnesses** (claude.ai Chat/Cowork/Design, Crush, Pi, LLM Council): the `capture` MCP tool, reached over the existing `/mcp` OAuth connector.
+
+Both doors call the **same** `CaptureService`; only the transport and credential assembly differ. The persistence behaviour (validation, classification, I1 gate, orchestration, I5 audit, partial receipt) is written once.

+- **`internal/capture/`** — the use-case + ports + entities. Pure; no I/O. Owns validation (fail-closed), effective-classification resolution (stricter wins), the **I1 sovereignty gate**, best-effort orchestration, the **two-phase I5 audit** (Reserve before writes / Record after), and the partial-aware receipt.
+- **`internal/brainstore/`** — concrete `BrainStore` wrapping the #45 `api` primitives + wiki upkeep (wing `_index`, auto-tunnel, graph re-index). The MCP `brain_write`/`brain_update`/`brain_get` handlers were re-pointed at it: one implementation, not two.
+- **`internal/classification/`** — `public < internal < confidential` taxonomy + per-wing/repo tags from an optional `classification.yaml`; fail-safe to confidential.
+- **`internal/gitea/`** — `IssueTracker` over the Gitea REST API; owner forced to `mathias`; token only in the Authorization header.
+- **`internal/capturehttp/`** — the REST adapter + the shared `Authenticate` / `DecodeRequest` / `OriginResolver` (also used by the MCP tool).
+- **`internal/audit/`** — `SlogSink` (default) and the `DegradingSink` (loki + durable `FileBuffer` + `NtfyNotifier` + `Reconcile`).
+- **`internal/mcp/`** — the `capture` relay tool + principal threading (re-derives the caller's principal from the Bearer header the chassis middleware discards).

+
+## 4. Invariant compliance
+
+| Inv | How satisfied |
+|-----|---------------|
+| **I1** sovereign containment | Effective classification = stricter(caller-declared, target-derived #50). Origin is **server-derived from the authenticated principal**, never `context.harness`. Confidential + us-nexus origin → refused before any write; refusal audited. Asserted-vs-derived mismatch → security event. |
+| **I2** deliberate acceptance | The relay's cross-harness reach is recorded in `infra/docs/security-baseline.md` with six containment properties + Revisit-if, **merged before relay code shipped** (infra #151). |
+| **I3** GitOps reconcilability | Env + `gitea-api-token` ExternalSecret under `infra/k3s/apps/supervisor/`, Flux-reconciled; image bumped by CD. No untracked runtime. |
+| **I5** auditability | Every capture emits a request-level audit record. Classification-aware degradation: confidential + sink-down → hard-refuse; internal/public + sink-down → durable local buffer + ntfy + reconcile-on-recovery; floor → refuse if nothing can record. |
+
+---
+
+## 5. Operational reference (env)
+
+Set on the `ingestion` deployment (`infra/k3s/apps/supervisor/ingestion-deployment.yaml`):
+
+| Env | Purpose | Notes |
+|-----|---------|-------|
+| `BRAIN_GITEA_URL` / `BRAIN_GITEA_TOKEN` | enables the `IssueTracker` → gates `/capture` + the MCP tool | token from 1P `DMABE_GITEA_API_TOKEN` via ESO; unset ⇒ capture disabled |
+| `BRAIN_LOKI_URL` | activates the `DegradingSink` | unset ⇒ `SlogSink` (audit to stdout → alloy → loki; no refuse/buffer semantics) |
+| `BRAIN_NTFY_URL` / `BRAIN_NTFY_TOKEN` | degraded-state alerts | optional |
+| `BRAIN_CAPTURE_SOVEREIGN_PRINCIPALS` | JWT subjects treated as sovereign-soil | comma-separated; static-token caller is always sovereign; unknown JWT ⇒ us-nexus (fail safe) |
+| `BRAIN_AUDIT_RECONCILE_INTERVAL` | buffer→loki replay tick | default 60s |
+
+The audit buffer lives at `<brain>/.audit-buffer/capture.jsonl` on the brain hostPath (nodeSelector-pinned to koala) — durable across restart without a separate PV.
+

+
+## 6. Tests
+
+67 test functions across the six packages. Coverage maps to the spec's Gherkin: happy path, supersede-not-duplicate, fail-closed validation, partial-failure receipt, dry-run, stricter-classification-wins, I1 confidential-via-us-nexus-refused / via-sovereign-allowed / asserted-label-ignored / caller-cannot-forge-origin, I5 confidential-refuse / internal-buffer / floor-refuse / reconcile / buffer-survives-restart, and the MCP relay tool (forwards, preserves principal, unauth rejected). `task check` green.
+
+---
+
+## 7. Deferred (not in this epic)
+
+Tracked here so they aren't lost; file as issues when picked up:
+
+- **SKILL veneer** — the `close-session` SKILL becomes the claude.ai trigger/harvest layer that calls capture.
+- **Per-harness token provisioning** for Crush / Pi / LLM Council (claude.ai is done via the existing `/mcp` connector).
+- **Harvest adapters** — transcript-parse vs chat-memory-reconstruct vs agent-runlog, each assembling capture args at its own fidelity.
+- **`SummaryWriter` impl** — ai-sessions summary persistence (the port + path logic exist; the concrete writer is nil today, so a request with a summary fails that one item).
