security: gate provider payload logging behind DIDACTYL_CONTEXT_DEBUG

The log_provider_payload_local() calls in perform_http_request() were unconditional, writing full LLM conversation transcripts (system prompts, user messages, tool calls, responses) to context.logs/ on every LLM call regardless of the DIDACTYL_CONTEXT_DEBUG setting. This caused 326 transcript files containing Nostr keys, relay URLs, and DM contents to be committed and pushed. Now the logging only runs when DIDACTYL_CONTEXT_DEBUG is set to 'init' or 'full' (matching the documented behavior in docs/CONTEXT.md). When unset or 'off', no transcripts are written to disk.
security: gitignore context.logs/, context.log.md, tasks.json

+# Signer Providers
+
+Didactyl can sign Nostr events and perform NIP-04/NIP-44 encryption either with
+an in-process private key (`local`) or by delegating to a running
+[`n_signer`](../n_signer) process over one of five transports. In any
+`nsigner_*` mode the agent process holds **no nsec** — the private key lives
+only in `n_signer`'s locked memory, and the agent pubkey is discovered at
+startup via `nostr_signer_get_public_key()`.
+
+## Modes
+
+| Mode | Transport | Holds nsec in agent? | Persistable to genesis? | Installable as systemd? |
+|------|-----------|----------------------|-------------------------|-------------------------|
+| `local` | in-process | yes | yes | yes |
+| `nsigner_unix` | AF_UNIX abstract socket | no | yes | yes |
+| `nsigner_tcp` | TCP `host:port` | no | yes | yes |
+| `nsigner_serial` | USB CDC-ACM serial | no | yes | yes |
+| `nsigner_fds` | pre-connected fd pair | no | **no** (runtime-only) | **no** |
+| `nsigner_qrexec` | Qubes qrexec (cross-qube) | no | yes | yes |
+
+### `local`
+Default, backward-compatible. The 32-byte private key is derived from
+`keys.nsec` and held in `cfg.keys.private_key`. Use this when you accept the
+nsec living in the agent process.
+
+### `nsigner_unix`
+Delegates to `n_signer` over an abstract namespace Unix socket
+(`@<socket_name>`). If `socket_name` is empty, the agent auto-discovers running
+`n_signer` sockets via `nsigner_transport_list_unix()`. Best for same-host
+deployments where `n_signer` runs in an attended terminal.
+
+### `nsigner_tcp`
+Delegates to `n_signer` over TCP. Requires `auth_privkey_hex` (64-char hex) for
+the kind-27235 auth envelope that `n_signer` enforces on TCP listeners. Use for
+cross-host or FIPS-mode deployments.
+
+### `nsigner_serial`
+Delegates to `n_signer` over a USB CDC-ACM serial device (e.g. `/dev/ttyACM0`).
+The wizard auto-discovers `/dev/ttyACM*` devices via
+`nsigner_transport_list_serial()`. Use for air-gapped/hardware-token signing.
+
+### `nsigner_fds`
+Delegates to `n_signer` over a pre-connected file-descriptor pair
+(`read_fd`, `write_fd`). Intended for qrexec-style fd-passing deployments.
+**Cannot be persisted to genesis** (fds are runtime-only) and **cannot be
+installed as a systemd service** (fds cannot be embedded in `ExecStart`). Supply
+via `--signer-fds <read:write>` at boot.
+
+### `nsigner_qrexec`
+Delegates to `n_signer` running in **another Qubes OS qube** via qrexec. The
+agent spawns `qrexec-client-vm <target_qube> <service_name>` as a subprocess
+and pipes framed JSON-RPC through its stdin/stdout. No network; caller identity
+is hypervisor-vouched (`QREXEC_REMOTE_DOMAIN` → `qubes:<source-vm>` on the
+signer side). This is the recommended Qubes cross-qube signing path.
+
+Prerequisites (in the signer qube, e.g. `nostr_signer`):
+- `n_signer` running persistently: `nsigner --listen unix --socket-name nsigner --bridge-source-trusted`
+- The `qubes.NsignerRpc` qrexec service installed (see `n_signer/packaging/qubes/`)
+- dom0 qrexec policy allowing the agent qube to call the service
+
+The service name defaults to `qubes.NsignerRpc`; override with `--signer-service`
+or the `signer.service_name` config field.
+
+## Configuration
+
+### Genesis (`signer` block)
+
+```jsonc
+"signer": {
+  "mode": "nsigner_unix",
+  "socket_name": "",               // nsigner_unix: "" = auto-discover
+  "role": "main",
+  "timeout_ms": 15000,
+  "auth_privkey_hex": "",          // nsigner_tcp only
+  "tcp_host": "127.0.0.1",         // nsigner_tcp
+  "tcp_port": 11111,               // nsigner_tcp
+  "serial_device": "/dev/ttyACM0", // nsigner_serial
+  "target_qube": "nostr_signer",   // nsigner_qrexec: target Qubes qube
+  "service_name": "qubes.NsignerRpc" // nsigner_qrexec: qrexec service (default qubes.NsignerRpc)
+  // nsigner_fds: fds_read_fd/fds_write_fd are CLI-only, NOT persisted here
+}
+```
+
+### CLI flags
+
+| Flag | Purpose |
+|------|---------|
+| `--signer <mode>` | Select signer mode (overrides config/env). |
+| `--signer-socket <name>` | Abstract socket name for `nsigner_unix`. |
+| `--signer-role <role>` | `n_signer` role selector (default `main`). |
+| `--signer-timeout <ms>` | Per-call timeout (default `15000`). |
+| `--signer-tcp <host:port>` | Shorthand for `--signer nsigner_tcp` + host/port. |
+| `--signer-serial <device>` | Shorthand for `--signer nsigner_serial` + device. |
+| `--signer-fds <read:write>` | Shorthand for `--signer nsigner_fds` + fd pair. |
+| `--signer-qrexec <target_qube>` | Shorthand for `--signer nsigner_qrexec` + target qube. |
+| `--signer-service <name>` | qrexec service name (default `qubes.NsignerRpc`). |
+
+Precedence: CLI flag > `DIDACTYL_SIGNER` env var > genesis `signer.mode` >
+default (`local`).
+
+In any `nsigner_*` mode, `--nsec` / `DIDACTYL_NSEC` are not required.
+
+## Interactive setup wizard
+
+The wizard's **New agent → sign with a running n_signer** path and the
+**Existing agent** flow both present a transport picker:
+
+- `u` nix socket (auto-discovers `@nsigner*` abstract sockets)
+- `t` cp (prompts for `host:port` + optional auth privkey)
+- `s` erial (auto-discovers `/dev/ttyACM*`)
+- `f` d pair (prompts for `read_fd:write_fd` — advanced)
+- `e` xec qrexec (prompts for target qube + service name — Qubes cross-qube)
+
+After a transport is chosen, the wizard runs a connectivity check
+(`nostr_signer_get_public_key`) and populates the agent pubkey before
+continuing.
+
+The **Existing agent** flow additionally lets you recover an agent **without
+entering an nsec** — kind-30078 config recall/publish is routed through the
+signer verbs (`nostr_signer_nip44_decrypt` / `nostr_signer_nip44_encrypt`), so
+the nsec never enters the agent process during recovery.
+
+## Systemd install
+
+`install_system_service_with_dedicated_user()` embeds the signer flags in
+`ExecStart` for `nsigner_unix`, `nsigner_tcp`, `nsigner_serial`, and
+`nsigner_qrexec`.
+`nsigner_fds` is rejected with a clear message (fds are runtime-only and cannot
+be embedded in `ExecStart`); choose **boot now** or wire fd-passing yourself
+via a wrapper unit.
+
+## Security tradeoff
+
+`local` keeps the nsec in the agent process. If the agent is compromised, the
+nsec is exposed. Remote (`nsigner_*`) modes keep the nsec in `n_signer`'s
+mlock'd memory; a compromised agent can request signatures but cannot extract
+the raw key. The tradeoff is operational: `n_signer` must be running and
+reachable when the agent needs to sign.

+
+…even though the required events (kind 31123/31124 skills and kind 10123 adoption list)
+demonstrably exist on `relay.laantungir.net` (verified with `nak`, returned in well under
+a second). On other restarts the identical setup succeeds: `ok (skills=3 adoptions=1)`.
+The failure is timing-dependent.
+
+## How startup relay polling works (mechanics)
+
+- Each startup step opens its **own** subscription (its own `REQ` + filter). Step 14's
+  filter is built in [`nostr_handler_subscribe_self_skills()`](src/nostr_handler.c:2800):
+  `{"kinds":[31123,31124,10123],"authors":[<agent_pubkey>],"limit":300}`.
+- That subscription is sent to **all** configured relays in parallel inside
+  [`nostr_relay_pool_subscribe()`](nostr_core_lib/nostr_core/core_relay_pool.c:967).
+- This is the **async/streaming** path: events arrive over time via
+  [`on_self_skill_event()`](src/nostr_handler.c:2478) which upserts into the shared cache
+  `g_self_skill_events`, and an EOSE-complete callback
+  ([`on_self_skill_eose`](src/nostr_handler.c:2066)) flips `g_self_skill_eose_received`.
+- Step 14 then immediately runs
+  [`nostr_handler_validate_self_skill_cache()`](src/nostr_handler.c:3089) against whatever
+  is in the cache at that instant.
+
+## Root cause
+
+The async EOSE-complete signal is decoupled from "did the relay that actually has the
+events get queried and deliver yet." Two independent contributing factors:
+
+1. **Relay connection timing.** The self-skill subscription is registered shortly after
+   startup. If `relay.laantungir.net` is not yet fully connected when the subscription's
+   completion is computed, the empty relays (`damus`, `primal`) EOSE almost instantly and
+   the per-relay **timeout fallback**
+   ([`core_relay_pool.c:2128`](nostr_core_lib/nostr_core/core_relay_pool.c:2128)) marks the
+   remaining relay "done" after `relay_timeout_seconds` (=12) without ever receiving its
+   events. EOSE-complete fires with an empty cache → validation fails.
+2. **Validation fires the instant completion is signaled**, with no re-check, so any race
+   where laantungir's events land microseconds later is lost.
+
+This matches the `<1s` `nak` observation: when laantungir is connected and queried, it
+answers almost instantly; the failures are the cycles where it wasn't
+connected/queried/processed before the async completion fired.
+
+### Why FIRST → FULL_SET alone does NOT fix it
+
+`maybe_complete_subscription_eose()` waits for **all** relays in both modes; the only
+difference is the payload passed to the callback. The cache is filled by the EVENT
+callback, not the EOSE payload. Changing the mode changes neither connection timing nor
+when events are available.
+
+## Fix: use the synchronous query for the startup self-skill load
+
+There is already a correct, synchronous "collect all events until EOSE/timeout, then
+return them" primitive used elsewhere at startup (e.g. kind-10002 discovery):
+
+- [`nostr_handler_query_json()`](src/nostr_handler.c:3395) →
+  [`nostr_relay_pool_query_sync()`](nostr_core_lib/nostr_core/core_relay_pool.c:1340).
+- A self-skill-specific wrapper already exists and reuses it:
+  [`nostr_handler_refresh_self_skill_cache_from_relays()`](src/nostr_handler.c:3751),
+  which queries kinds 31123/31124/10123 for the agent author (and also pulls adopted
+  skills), populating the cache synchronously.
+
+The synchronous query is the architecturally correct tool for "give me the complete
+current set before proceeding," which is exactly what step 14 needs. It also drives the
+poll/receive loop itself
+([`core_relay_pool.c:1405`](nostr_core_lib/nostr_core/core_relay_pool.c:1405)) until all
+connected relays EOSE or the timeout elapses.
+
+### Important caveat to handle: connection readiness
+
+`nostr_relay_pool_query_sync()` only queries relays that are **connected at call time**
+(`if (connected_count == 0) return NULL;` at
+[`core_relay_pool.c:1392`](nostr_core_lib/nostr_core/core_relay_pool.c:1392)). If
+`relay.laantungir.net` is still mid-connect when step 14 runs, a sync query could still
+miss it. Therefore the fix must ensure the relay holding the events is connected (or wait
+briefly for it) before/within the query.
+
+### Plan
+
+1. **Replace the step-14 async wait+validate with a synchronous load.** In
+   [`src/main.c`](src/main.c) step 14 (~line 1518), instead of relying solely on
+   `nostr_handler_wait_for_self_skill_eose()` + an immediate
+   `nostr_handler_validate_self_skill_cache()`:
+   - Keep registering the live subscription (so ongoing skill updates still stream in via
+     `on_self_skill_event`) — this is still wanted for runtime.
+   - For the startup *gate*, call
+     [`nostr_handler_refresh_self_skill_cache_from_relays(timeout_ms)`](src/nostr_handler.c:3751)
+     with a sensible timeout (e.g. 8000–10000 ms). This performs the synchronous,
+     connection-aware query and fills `g_self_skill_events`.
+   - Then run `nostr_handler_validate_self_skill_cache(&skills, &adoptions)`.
+
+2. **Wait for the self relay (laantungir) to be connected before the sync query.** Reuse
+   the existing relay-readiness helper pattern (`wait_for_connected_relays`) — but ensure
+   we wait specifically until the relay list discovered from kind 10002 (which includes
+   `relay.laantungir.net`) is connected, not just "any relay." If we already have a
+   connected-count wait, extend/bound it so the relay that owns the events has a fair
+   chance to connect before the sync query runs.
+
+3. **Bounded retry around the sync query.** If the first sync query returns an empty cache,
+   retry the sync query a small, bounded number of times (e.g. up to ~5–8s total),
+   pumping `nostr_handler_poll()` between attempts to let connections settle. Only fail
+   step 14 after the bounded retries still yield an empty cache. This converts a transient
+   connection-timing miss into a brief wait instead of a hard failure.
+
+4. **Keep the async subscription for runtime updates.** Do not remove the live
+   subscription; it's still responsible for picking up skill changes after startup. Only
+   the *startup gate* switches to the synchronous load for determinism.
+
+### Why this is the right layer
+
+- It uses the library's intended synchronous collect-all primitive rather than racing a
+  streaming subscription against an immediate validation.
+- It is connection-aware and bounded, so a slow/late relay connect becomes a short wait,
+  not a false "no skill events" failure.
+- It does not require modifying `nostr_core_lib` (though if desired, a follow-up could add
+  a `query_sync` variant that waits for a named relay to connect; not required here).
+
+## Interaction with the failure-DM throttle (already shipped)
+
+- On success, the READY path clears the throttle marker
+  ([`src/main.c`](src/main.c) `startup_failure_marker_clear`). No change needed.
+- After this fix, step-14 failures should be genuinely rare (real outage / events truly
+  absent), and the (single, throttled) failure DM will carry relay states + needed event
+  kinds for accurate diagnosis.
+
+## Verification
+
+1. Build (`make`) clean, then `build_static.sh`.
+2. Deploy to VM410; restart both services many times in a row and confirm step 14 reaches
+   `ok (skills=N adoptions=M)` **consistently** (no intermittent false negatives).
+3. Inspect logs to confirm the synchronous query path is used and that, on a cold cycle,
+   it waits for `relay.laantungir.net` to connect and then returns the events.
+4. Negative test: configure only empty relays (no skill events anywhere) and confirm step
+   14 still fails after the bounded retries (no false positive), sending exactly one
+   throttled failure DM.
+5. Confirm a normal successful startup still sends the startup DM and clears the marker.
+
+## Out of scope (possible follow-ups)
+
+- Adding a `nostr_core_lib` `query_sync` variant that explicitly waits for specific
+  relays to connect before issuing the REQ.
+- Softening step 14 into a degraded-start mode.

+# Fix: Trigger Manager Bypasses Skill Adoption List
+
+## Problem
+
+`trigger_manager_load_from_skills()` and `trigger_manager_reconcile_from_relays()`
+activate cron/webhook/subscription triggers for **every** self-authored skill event
+(kind 31123/31124) that has trigger metadata, without checking whether the skill is
+on the kind 10123 adoption list.
+
+This means a skill that was published but never adopted (or was un-adopted) will
+still have its cron trigger firing.
+
+Contrast: `agent.c:refresh_adopted_skills_cache_if_needed()` properly fetches the
+kind 10123 list, parses `"a"` tags, and only loads adopted skills — and also checks
+the `enabled` tag. The trigger manager was written as a parallel system that skips
+both gates.
+
+## Root Cause
+
+- `trigger_manager.c:939` — `trigger_manager_load_from_skills()`: no reference to
+  kind 10123 or adoption anywhere in the function. Calls `trigger_manager_add()`
+  unconditionally.
+- `trigger_manager.c:592` — `trigger_manager_reconcile_from_relays()`: same bug.
+  Currently disabled (`enable_periodic_reconcile = 0` at line 1575) but should be
+  fixed before re-enabling.
+- Neither function checks the `enabled` tag either, unlike
+  `trigger_manager_load_from_startup_events()` (line 1078) which does check it.
+
+## Fix
+
+### 1. Add a static helper: `load_adopted_d_tags()`
+
+Add a static function in `trigger_manager.c` that:
+- Fetches kind 10123 events via `nostr_handler_get_self_events_by_kind_json(10123)`
+- Selects the latest event by `created_at` (same logic as agent.c)
+- Parses `"a"` tags using a local `parse_skill_address_tag_local()` equivalent
+- Populates a fixed-size array of adopted d_tag strings
+- Returns the count
+
+Since both call sites only deal with self-authored skills, matching on d_tag
+alone is sufficient (the pubkey in the "a" tag will be the agent's own).
+
+### 2. Add `enabled` tag check
+
+Both functions should read the `enabled` tag (defaulting to `"true"`) and skip
+skills where `enabled` is `false` or `0`, matching the pattern already used in
+`trigger_manager_load_from_startup_events()`.
+
+### 3. Gate `trigger_manager_load_from_skills()`
+
+Before calling `trigger_manager_add()`, check:
+1. The skill's d_tag is in the adopted set
+2. The skill's `enabled` tag is not false/0
+
+If the adoption list is empty or missing, log a warning and load nothing (do not
+fall back to loading all skills — that's the bug).
+
+### 4. Gate `trigger_manager_reconcile_from_relays()`
+
+Apply the same adoption + enabled checks. This ensures the code is correct when
+`enable_periodic_reconcile` is eventually flipped back to 1.
+
+### 5. Pass `is_enabled` to `trigger_manager_add()`
+
+Currently both functions pass `1` (hardcoded enabled) as the `enabled` parameter.
+Change to pass the actual `is_enabled` value derived from the `enabled` tag.
+
+## Files Changed
+
+- `src/trigger_manager.c` — add helper, fix both functions
+
+## Risk
+
+Low. The fix adds a filter before `trigger_manager_add()`. If the adoption list
+is present and correct, behavior is unchanged for adopted skills. If the adoption
+list is missing, triggers simply won't load (which is the correct behavior —
+nothing should fire if nothing is adopted).

+# n_signer Integration Plan — didactyl
+
+## Goal
+
+Separate control of the nsec from the didactyl agent by routing signing/encryption
+through `n_signer` — a separate foreground process that holds key material in locked
+memory and signs on request. A later phase may embed n_signer into the didactyl binary
+so one self-contained binary spawns an n_signer in a separate window; that is deferred
+because of a reliability concern (if the agent loses signing ability it cannot even DM
+its admin about the failure).
+
+This plan covers two distinct work items:
+
+1. **Update didactyl's vendored `nostr_core_lib`** to the upstream version that already
+   implements the nsigner client (M1–M6 complete, upstream `VERSION` 0.6.6). This is a
+   mechanical sync that changes no runtime behavior.
+2. **Opt-in migration of didactyl call sites** to the `nostr_signer_t` provider so the
+   raw private key can leave the agent process. This is the actual nsec-separation work
+   and is staged so reliability is preserved.
+
+---
+
+## Background — what upstream already provides
+
+Upstream `nostr_core_lib` (git.laantungir.net/nostr_core_lib, v0.6.6) has shipped the
+full signer abstraction. didactyl's vendored copy predates all of it.
+
+New upstream modules:
+
+- [`nostr_core/nostr_signer.{h,c}`](../nostr_core_lib/nostr_core/nostr_signer.h) —
+  `nostr_signer_t` opaque handle + vtable. Two backends:
+  - **local** — `nostr_signer_local(privkey[32])`, wraps today's raw-key path. Output-equivalent.
+  - **remote (nsigner)** — `nostr_signer_nsigner_unix/serial/tcp/fds(...)`, guarded by
+    `NOSTR_ENABLE_NSIGNER_CLIENT`.
+- [`nostr_core/nsigner_client.{h,c}`](../nostr_core_lib/nostr_core/nsigner_client.h) —
+  framing, JSON-RPC verbs, kind-27235 auth envelope, error mapping.
+- [`nostr_core/nsigner_transport.{h,c}`](../nostr_core_lib/nostr_core/nsigner_transport.h) —
+  pluggable transport vtable: AF_UNIX abstract, TCP, USB-CDC serial, fd-pair (stdio/qrexec).
+
+Verbs mirror n_signer's wire contract: `get_public_key`, `sign_event`,
+`nip04_encrypt/decrypt`, `nip44_encrypt/decrypt`.
+
+Parallel `*_with_signer` entry points added across the library (legacy raw-key APIs are
+preserved as thin wrappers over the local backend, so existing projects keep compiling
+and behaving identically):
+
+- NIP-01: `nostr_create_and_sign_event_with_signer`
+- NIP-17: `nostr_nip17_create_relay_list_event_with_signer`,
+  `nostr_nip17_send_dm_with_signer`, `nostr_nip17_receive_dm_with_signer`
+- NIP-42: `nostr_nip42_create_auth_event_with_signer`
+- NIP-46: request/response/decrypt/session-init `*_with_signer` variants
+- NIP-59: seal/unwrap/unseal `*_with_signer` variants
+- NIP-60 / NIP-61: all cashu event-creation `*_with_signer` variants
+- Blossom: `blossom_create_auth_header_with_signer`,
+  `blossom_upload_with_signer`, `blossom_upload_file_with_signer`,
+  `blossom_delete_with_signer`
+- Relay pool: `nostr_relay_pool_set_auth_with_signer` — the pool now stores an
+  `auth_signer` instead of a raw key, so NIP-42 AUTH events are signed through the
+  provider on relay challenge. **This was the hardest blocker and it is already solved
+  upstream.**
+
+Upstream `build.sh` unconditionally defines `-DNOSTR_ENABLE_NSIGNER_CLIENT=1` and
+compiles `nostr_signer.c`, `nsigner_transport.c`, `nsigner_client.c`.
+
+Dependency direction is unchanged and non-circular: n_signer (server) depends on
+`nostr_core_lib` for leaf crypto; `nostr_core_lib` gains a *client* that consumes its
+own primitives. Nobody imports anyone's binary in a loop.
+
+---
+
+## Current didactyl state (what we are updating from)
+
+- `nostr_core_lib/` is a **vendored source directory** (no git submodule; no
+  `.gitmodules`). Built via `./nostr_core_lib/build.sh --nips=001,004,...,061` into a
+  static `libnostr_core_*.a`, linked by [`Makefile`](../Makefile:56) and the Docker
+  static build ([`Dockerfile.alpine-musl`](../Dockerfile.alpine-musl:81)).
+- The vendored tree has **none** of the nsigner pieces: no `nostr_signer.*`,
+  no `nsigner_*.*`, no `*_with_signer` variants. The relay pool still uses the raw-key
+  AUTH path ([`nostr_core_lib/nostr_core/core_relay_pool.c`](../nostr_core_lib/nostr_core/core_relay_pool.c:682)).
+- didactyl holds the raw 32-byte key in [`cfg->keys.private_key`](../src/config.h:16)
+  and passes it directly into ~30+ library call sites (event signing, NIP-04/44
+  encrypt/decrypt, NIP-17 gift wraps, NIP-60/61 cashu, blossom, relay pool AUTH).
+
+---
+
+## Architecture (target)
+
+```mermaid
+graph TD
+    A[didactyl src] --> B[nostr_core_lib vendored]
+    B --> C[nostr_signer_t local backend]
+    B --> D[nostr_signer_t nsigner remote backend]
+    D --> E[nsigner client: framing + auth envelope]
+    E --> F[nostr_create_and_sign_event in nostr_core_lib]
+    G[n_signer server binary] --> B
+```
+
+didactyl constructs **one** `nostr_signer_t*` at startup and threads it through every
+signing/encryption/AUTH call site. The backend is chosen by config:
+
+- `signer.mode = "local"` → `nostr_signer_local(cfg->keys.private_key)` (today's behavior).
+- `signer.mode = "nsigner_unix"` → `nostr_signer_nsigner_unix(socket_name, role, timeout_ms)`.
+- (future) `nsigner_tcp`, `nsigner_serial`, `nsigner_fds`.
+
+The raw `cfg->keys.private_key` is only populated in `local` mode. In remote modes the
+agent process never holds the nsec; it learns its own pubkey via
+`nostr_signer_get_public_key()`.
+
+---
+
+## Phasing
+
+### Phase 1 — Update vendored nostr_core_lib (mechanical, zero behavior change)
+
+Goal: bring didactyl's `nostr_core_lib` source tree to upstream v0.6.6 so the signer
+abstraction and nsigner client are available. **No didactyl source changes.** Existing
+raw-privkey APIs are preserved upstream as thin wrappers over the local backend, so all
+~30 call sites keep compiling and behaving identically.
+
+Steps:
+
+1. Snapshot current vendored tree for diffing/rollback:
+   `cp -a nostr_core_lib nostr_core_lib.old`
+2. Replace the vendored source tree with upstream v0.6.6. Preferred: copy the upstream
+   `nostr_core/`, `cjson/`, `nostr_websocket/`, `platform/`, `build.sh`, `CMakeLists.txt`
+   into `nostr_core_lib/`, preserving didactyl-local build quirks only if any exist
+   (none found — the Dockerfile already `sed`s `build.sh` in-place for fortification).
+   Do **not** carry over upstream's prebuilt `.a`/`.o` files, `pool.log`, `.venv*`,
+   `backups/`, `verify_*` artifacts — match didactyl's existing `.gitignore` hygiene.
+3. Rebuild the static library:
+   `cd nostr_core_lib && ./build.sh --nips=001,004,005,006,011,013,017,019,021,042,044,046,059,060,061`
+   (same NIP set as today; `nostr_signer.c` / `nsigner_*.c` are compiled unconditionally
+   by upstream `build.sh`).
+4. Rebuild didactyl: `make clean && make`. Confirm it compiles and links with no source
+   changes.
+5. Smoke test: run the agent with an nsec-only config and confirm signing/DMs/relay AUTH
+   still work byte-for-byte (the upstream local backend is output-equivalent to the
+   legacy path; there is an upstream test `test_event_creation_equivalence_with_signer`
+   that asserts this).
+6. Static (Docker) build: `./build_static.sh`. The Dockerfile copies `nostr_core_lib/`
+   and runs `./build.sh --nips=all`; verify the static binary still builds and runs.
+7. Record the upstream version pinned in this repo (e.g. a one-line
+   `nostr_core_lib/UPSTREAM_VERSION` file = `0.6.6`) so future syncs are auditable.
+
+Exit criteria: didactyl builds and runs identically, but now links a `nostr_core_lib`
+that exposes `nostr_signer_t` and the nsigner client. No nsec separation yet.
+
+### Phase 2 — Signer provider in didactyl config + startup (local backend, still no separation)
+
+Goal: introduce a `nostr_signer_t*` in didactyl constructed at startup, backed by
+`local` mode by default. This is the seam; behavior is still identical.
+
+#### 2a. Config schema
+
+[`src/config.c`](../src/config.c) / [`src/config.h`](../src/config.h): add a `signer`
+block (sibling of `keys`):
+
+```jsonc
+"signer": {
+  "mode": "local",            // "local" | "nsigner_unix" | (future) "nsigner_tcp" | "nsigner_serial" | "nsigner_fds"
+  "socket_name": "",          // nsigner_unix: abstract socket name (without @); empty = auto-discover single running signer
+  "role": "main",             // n_signer role selector
+  "timeout_ms": 15000,
+  "auth_privkey_hex": ""      // optional, for TCP auth envelope only
+}
+```
+
+Default `mode = "local"`. Backward compatible: if `signer` block is absent, behave as
+`local` using `keys.nsec`. Validation: in any `nsigner_*` mode, `keys.nsec` is optional
+and ignored (the agent learns its pubkey from the signer); in `local` mode `keys.nsec`
+remains required.
+
+#### 2b. User-facing surfaces (how the operator chooses n_signer)
+
+didactyl has three startup surfaces today; the n_signer choice is exposed on all three,
+consistent with existing patterns:
+
+**1. Interactive setup wizard** ([`src/setup_wizard.c`](../src/setup_wizard.c),
+`new_agent_identity_step` at line ~2116). Today the Identity page offers:
+`[g]enerate new keypair` / `[p]rovide existing nsec`. Add a third option:
+
+- `[s]ign with a running n_signer (separate the nsec from the agent)`
+
+When chosen, the wizard:
+- Does **not** prompt for an nsec. Instead prompts for:
+  - socket name (default: auto-discover the single running signer),
+  - role (default `main`),
+  - timeout (default 15000ms).
+- Performs a live `nostr_signer_nsigner_unix(...)` + `nostr_signer_get_public_key()`
+  connectivity check immediately, so the operator gets confirmation ("Connected to
+  n_signer @nsigner_hairy_dog; agent npub: npub1...") before proceeding.
+- Writes `signer.mode = "nsigner_unix"` (plus socket_name/role/timeout) into the
+  generated genesis JSONC and **omits** `keys.nsec`.
+- The existing `[p]rovide existing nsec` path stays as `local` mode (the default).
+
+This keeps the trust model visible at the moment the operator commits to an identity:
+either the nsec lives in the agent (`local`) or it does not (`nsigner_unix`).
+
+**2. CLI flags + env** ([`src/main.c`](../src/main.c) `print_usage` at line ~141 and
+arg parsing at line ~1233). Add:
+
+- `--signer <mode>` — one of `local`, `nsigner_unix`, `nsigner_tcp`, `nsigner_serial`,
+  `nsigner_fds`. Overrides `signer.mode` in config.
+- `--signer-socket <name>` — abstract socket name (nsigner_unix).
+- `--signer-role <role>` — n_signer role selector (default `main`).
+- `--signer-timeout <ms>` — per-call timeout (default 15000).
+- `--signer-tcp <host:port>` — shorthand for `--signer nsigner_tcp` + host/port.
+- `DIDACTYL_SIGNER` env — fallback for `--signer` (mirrors the `DIDACTYL_NSEC` pattern).
+
+When `--signer nsigner_unix` (or `DIDACTYL_SIGNER=nsigner_unix`) is set, `--nsec` /
+`DIDACTYL_NSEC` are not required and are ignored if present. This enables headless /
+systemd deployment where the nsec never touches the agent's argv or environment.
+
+Update `print_usage` examples to show the n_signer path, e.g.:
+`%s --signer nsigner_unix --signer-socket nsigner_hairy_dog --admin npub1...`
+
+**3. Genesis JSONC config** — the `signer` block in 2a is the canonical, persistent
+form. The wizard writes it; CLI flags override it for a single run; env vars are the
+last fallback. This matches how `keys.nsec` / `--nsec` / `DIDACTYL_NSEC` already layer.
+
+Precedence (highest to lowest): CLI flag → env var → genesis `signer` block → default
+`local`. Same precedence as the existing key/admin overrides.
+
+#### 2c. Startup construction
+
+[`src/main.c`](../src/main.c): after loading config + applying CLI/env overrides,
+construct a single `nostr_signer_t* g_signer`:
+
+- `local` → `nostr_signer_local(cfg->keys.private_key)`.
+- `nsigner_unix` → `nostr_signer_nsigner_unix(socket_name, role, timeout_ms)`.
+- (future) `nsigner_tcp` / `nsigner_serial` / `nsigner_fds` analogously.
+
+Then derive the agent pubkey via `nostr_signer_get_public_key(g_signer, ...)` instead of
+`nostr_ec_public_key_from_private_key(cfg->keys.private_key, ...)`. In `local` mode this
+yields the same bytes; in remote mode it is the first n_signer round-trip and **doubles
+as the mandatory startup connectivity check** (Phase 4): failure here is fatal and loud.
+
+Hold `g_signer` alongside `g_cfg` / `g_pool` for the process lifetime; free on shutdown.
+
+Exit criteria: didactyl runs with a `nostr_signer_t*` in `local` mode by default, and
+the operator can choose `nsigner_unix` via wizard, CLI, or config. No call sites migrated
+yet (Phase 3). This is a safe, reviewable checkpoint — in `local` mode behavior is
+identical; in `nsigner_unix` mode the agent starts but signing still uses the local path
+until Phase 3 lands (so Phase 2 remote mode is a connectivity proof, not full separation).
+
+### Phase 3 — Migrate call sites to `*_with_signer` (enables real separation)
+
+Goal: route every signing/encryption/AUTH operation through `g_signer`. In `local` mode
+this is still output-equivalent; in `nsigner_unix` mode the nsec is no longer in the
+agent process.
+
+Migrate in this order (highest value / lowest risk first):
+
+1. **Relay pool AUTH** — replace
+   `nostr_relay_pool_set_auth(g_pool, g_cfg->keys.private_key, 1)` with
+   `nostr_relay_pool_set_auth_with_signer(g_pool, g_signer, 1)`. This is the single
+   change that delegates the deep-event-loop AUTH signing.
+2. **Event signing** — `nostr_create_and_sign_event(...)` →
+   `nostr_create_and_sign_event_with_signer(...)` at all sites (posts, kind 30078
+   config publish, startup events, etc.). Search: `nostr_create_and_sign_event` in
+   `src/`.
+3. **NIP-44 encrypt/decrypt** — the DM/memory/task/config/block-list sites. These call
+   `nostr_nip44_encrypt/decrypt(cfg->keys.private_key, peer, ...)`. Replace with
+   `nostr_signer_nip44_encrypt/decrypt(g_signer, peer_hex, ...)`. Note the signer API
+   takes hex pubkeys and returns heap strings via `char**` out-params, so each call site
+   needs a small adaptation (hex-encode the peer key, free the out-string).
+4. **NIP-04 encrypt/decrypt** — same pattern as NIP-44 for the legacy NIP-04 DM sites.
+5. **NIP-17 gift wraps** — `nostr_nip17_send_dm` / `nostr_nip17_receive_dm` →
+   `*_with_signer`. (The seal is signed with the agent key via the signer; the gift-wrap
+   ephemeral key stays local — that is correct and does not leak the nsec.)
+6. **NIP-60/61 cashu** — `nostr_nip60_create_*_event` / `nostr_nip61_create_*_event` →
+   `*_with_signer` in [`src/cashu_wallet.c`](../src/cashu_wallet.c).
+7. **Blossom** — `blossom_create_auth_header` / `blossom_upload` / `blossom_delete` →
+   `*_with_signer` in [`src/tools/tool_blossom.c`](../src/tools/tool_blossom.c).
+
+After each group, build + smoke test in `local` mode (output-equivalent) before
+testing in `nsigner_unix` mode against a running `n_signer`.
+
+Exit criteria: every signing/encryption/AUTH op flows through `g_signer`. With
+`signer.mode = "nsigner_unix"`, the agent process holds no nsec.
+
+### Phase 4 — Reliability & failure handling (critical, do before enabling remote by default)
+
+The user's stated concern: if the agent loses signing ability, it cannot even DM its
+admin about the failure. This must be addressed before remote mode is anything but
+opt-in.
+
+Design:
+
+- **Startup connectivity check is mandatory.** `nostr_signer_get_public_key()` is called
+  at startup for every mode. In remote mode, failure here is fatal and loud (agent
+  refuses to start, prints a clear error). Better to fail to start than to start unable
+  to sign.
+- **Runtime signing failure** — classify by error:
+  - `approval_denied` / `policy_denied` / `unknown_role` → not a transient error; surface
+    to agent log and admin context, do not retry blindly.
+  - transport/IO error (n_signer crashed, socket gone) → the nsigner transport has a
+    `reconnect` hook; the client retries once with reconnect, then returns an error.
+- **Admin notification path.** Because DMs themselves require signing, a signing outage
+  is a catch-22 for "DM the admin". Mitigations, in order of preference:
+  1. **Health-gate before sending.** Before attempting an admin DM, do a cheap
+     `nostr_signer_get_public_key()` ping. If it fails, fall back to a **local,
+     keyless** notification channel: stderr/log + HTTP API health endpoint
+     ([`src/http_api.c`](../src/http_api.c)) exposes a `signer_unhealthy` flag. The admin
+     monitors the HTTP health endpoint (or process supervisor) rather than relying on a
+     DM that requires the broken signer.
+  2. **Optional emergency local key.** A config-gated `signer.emergency_local_nsec`
+     used *only* to sign admin DMs when the remote signer is unreachable. This is a
+     deliberate policy tradeoff (it re-introduces a key in-process, scoped to admin
+     alerts only) and should be off by default. Document the tradeoff clearly.
+  3. **Process supervisor.** systemd/`didactyl` service restarts on signer health
+     failure; the supervisor's logs are the out-of-band channel.
+- **Recommendation for v1:** ship (1) + (3). Leave (2) as a documented opt-in for
+  operators who prioritize alert delivery over strict key separation. This keeps the
+  default trust model clean while making the failure observable out-of-band.
+
+Exit criteria: a signing outage is detectable out-of-band (HTTP health + logs +
+supervisor), and the agent does not silently hang. Remote mode is still opt-in.
+
+#### Phase 4 implementation status (items 18–20) — COMPLETE
+
+Items 18, 19, and 20 are implemented as follows. Behavior is backward compatible
+and remote mode remains opt-in.
+
+**Item 18 — Runtime signer health classification & tracking**
+
+- New module [`src/signer_health.{h,c}`](../src/signer_health.h) holds a
+  process-global, mutex-protected health state: `unknown | healthy | unhealthy`,
+  the configured signer mode snapshot, the last error reason string, and the
+  last error / last ok unix timestamps.
+- [`src/main.c`](../src/main.c) `construct_signer()` records the mode at startup
+  and records `ok` on a successful connectivity check (`get_public_key`) or
+  `failure` (with the nostr error code) on construction/connectivity failure.
+  The fatal+loud startup behavior is preserved; error messages now explicitly
+  include `mode=`, `socket=`, `role=`, `timeout_ms=`, and `rc=` so the operator
+  knows exactly which signer context failed.
+- The migrated signer call paths in [`src/nostr_handler.c`](../src/nostr_handler.c)
+  (NIP-44 self encrypt/decrypt, NIP-04 incoming DM decrypt, NIP-04 outgoing DM
+  encrypt) call `signer_health_record_ok()` on success and
+  `signer_health_record_failure(rc, "<verb>")` on failure. Classification maps
+  nostr error codes to short labels: `transport/IO` (IO/network), `crypto/auth`,
+  `resource`, `invalid-input`, `unknown`. This is deliberately minimal — no broad
+  rewrite of the tool/agent/cashu/block-list signer sites; the central DM and
+  self-config paths are instrumented, which is where an outage first surfaces.
+
+**Item 19 — Out-of-band health surface (HTTP + logs + supervisor)**
+
+- [`src/http_api.c`](../src/http_api.c) `handle_status()` (the `GET /api/status`
+  endpoint) now adds the following fields to the JSON response:
+  - `signer_mode` — the configured signer mode (`local` / `nsigner_unix` / `nsigner_tcp`).
+  - `signer_healthy` — `"true"` / `"false"` / `"unknown"`.
+  - `signer_health_state` — `healthy` / `unhealthy` / `unknown`.
+  - `signer_last_error` — human-readable `<classification>: <detail> (rc=<n>)`, or `""`.
+  - `signer_last_error_ts` — unix timestamp of the last unhealthy transition, or `null`.
+  - `signer_last_ok_ts` — unix timestamp of the last healthy observation, or `null`.
+  An operator (or supervisor / monitoring agent) can poll `/api/status` to detect a
+  signing outage without requiring a signed admin DM to come back.
+- `signer_health_record_failure()` and `signer_health_record_ok()` each emit a
+  one-line stderr warning on a health **transition** (healthy -> unhealthy, or
+  unhealthy -> healthy), including the mode and reason. Repeated failures within
+  the same unhealthy state do not spam the log.
+
+**Item 20 — Optional `emergency_local_nsec` (admin-DM delivery tradeoff)**
+
+- New config field `signer.emergency_local_nsec` (string, empty default) in
+  [`src/config.h`](../src/config.h) `signer_config_t`, parsed in
+  [`src/config.c`](../src/config.c) `parse_signer_config()`.
+- **No active fallback behavior is wired yet.** The field is parsed, stored, and
+  documented only — a feature-flag/placeholder so operators can pre-stage the
+  value. The actual "sign a minimal admin-alert DM with the emergency key when
+  the remote signer is unreachable" path is deferred until the Phase 4 health
+  surface (item 19) is proven in production.
+- **Tradeoff (documented here and in the config header comment):** off by default.
+  When eventually enabled, it reintroduces the nsec into the agent process
+  *only* for admin-alert fallback DMs. This is a deliberate operator-accepted
+  tradeoff: better to leak the nsec briefly to notify the admin than to fail
+  silently. Operators who prioritize strict key separation leave it empty and
+  rely on the HTTP health endpoint + supervisor logs (item 19) as the
+  out-of-band alert channel.
+
+**Validation**
+
+- `make clean && make` builds cleanly with the new `signer_health.c` source.
+- `./didactyl --help` and `./didactyl --version` unchanged in surface.
+- `GET /api/status` in local mode returns the new `signer_mode` / `signer_healthy`
+  / `signer_health_state` / `signer_last_error` / `signer_last_error_ts` /
+  `signer_last_ok_ts` fields (local mode reports `signer_healthy=true` after the
+  startup connectivity check).
+
+### Phase 5 (deferred) — Embedded n_signer spawn
+
+Goal: one self-contained didactyl binary that spawns an n_signer in a separate window
+at startup, for operators who want key separation without running a second process
+manually.
+
+Deferred because of the reliability concern above and because it couples didactyl's
+process model to n_signer's TUI/terminal-attached trust model. Revisit after Phase 4's
+health/observability story is proven in production with an external n_signer.
+
+Sketch (not for this round): didactyl forks `n_signer --mnemonic-fd N --socket-name <pinned>`
+in a new terminal (xterm/foot/etc.), passes the mnemonic over a pipe fd, pins the
+abstract socket name, and constructs `nostr_signer_nsigner_unix(<pinned name>, ...)`.
+The pinned socket name avoids discovery races. The trust anchor is still the
+terminal-attached n_signer process; didactyl is just a supervised spawner.
+
+---
+
+## Open decisions (resolved)
+
+1. **Where does the abstraction live?** Inside `nostr_core_lib`. It is the single
+   chokepoint, it solves the relay-AUTH blocker, and it is reusable. ✓ (already done
+   upstream)
+2. **How is the n_signer client code sourced into nostr_core_lib?** Already decided
+   upstream: the client (framing + auth envelope + transports) lives in
+   `nostr_core_lib` itself, guarded by `NOSTR_ENABLE_NSIGNER_CLIENT`. No vendoring of
+   n_signer's repo into nostr_core_lib; n_signer keeps depending on nostr_core_lib for
+   leaf crypto. ✓
+3. **Runtime failure handling.** See Phase 4: out-of-band health (HTTP + logs +
+   supervisor) by default; optional emergency-local-nsec as documented opt-in. ✓
+
+---
+
+## Risks & notes
+
+- **NIP set in `Makefile` vs `build.sh --nips=all` in Dockerfile.** Both must include
+  the NIPs didactyl uses. The signer core (`nostr_signer.c`, `nsigner_*.c`) is compiled
+  unconditionally by upstream `build.sh`, so the nsigner client is available in both
+  build paths. Verify after sync.
+- **Static link footprint.** nsigner client + transports add a small amount of object
+  code (unix/tcp/serial/fd transports). Negligible vs. the existing websocket/curl/openssl
+  surface. Serial transport pulls in `<termios.h>` — already POSIX, fine for musl.
+- **Output equivalence.** Upstream's local backend is asserted equivalent by
+  `test_event_creation_equivalence_with_signer`. Phase 1 smoke test should still
+  verify a known event signs to the same id as before.
+- **`cfg->keys.private_key` lifetime.** In remote mode this buffer is zeroed/unused.
+  Keep the field for `local` mode and for the optional emergency key; do not remove it.
+- **Hex pubkey plumbing.** The signer's encrypt/decrypt verbs take hex pubkeys and
+  return heap strings. Several didactyl sites currently pass raw 32-byte keys. Each
+  migrated site needs a small hex-encode + free adaptation. Mechanical but touches
+  many files — Phase 3 step 3/4 is the bulk of the work.

+# Remove Dead DM-History Helper Functions in `agent.c`
+
+## Background
+
+While investigating how Didactyl maintains continuity across a DM "chat session", two functions in [`src/agent.c`](../src/agent.c) were found to be compiled-but-unreferenced, marked with `__attribute__((unused))` to suppress compiler warnings:
+
+- [`append_recent_admin_dm_history`](../src/agent.c:1065)
+- [`build_recent_admin_dm_history_messages`](../src/agent.c:1800) (wraps the above)
+
+These were part of an older design where the agent automatically injected the last N admin DM turns into every LLM call. The current architecture is **skill-driven**: DM history only reaches the LLM when an adopted, triggered skill explicitly pulls it in via the `{{dm_history}}` / `{{nostr_dm_history(...)}}` template variables or the `nostr_dm_history` tool (see [`tool_agent.c`](../src/tools/tool_agent.c:284) and [`tools_schema.c`](../src/tools/tools_schema.c:1606)). The dead functions are now a source of confusion for anyone reading the code to understand chat-session behavior.
+
+## Goal
+
+Remove the dead functions and any symbols used exclusively by them, without changing runtime behavior.
+
+## Scope Analysis (verified before planning)
+
+A repo-wide search for each symbol confirmed the following:
+
+| Symbol | Only callers | Disposition |
+|---|---|---|
+| [`append_recent_admin_dm_history`](../src/agent.c:1065) | called by `build_recent_admin_dm_history_messages` (also dead) | **delete** |
+| [`build_recent_admin_dm_history_messages`](../src/agent.c:1800) | no callers | **delete** |
+| [`AGENT_HISTORY_TURNS`](../src/agent.c:38) | referenced only inside the dead `append_recent_admin_dm_history` | **delete** |
+| [`AGENT_HISTORY_QUERY_LIMIT`](../src/agent.c:39) | defined but zero references repo-wide | **delete** |
+| [`append_simple_message`](../src/agent.c:187) | many live callers throughout `agent.c` | **keep** |
+| [`nostr_handler_get_dm_history_json`](../src/nostr_handler.c:4384) | live via [`tool_agent.c`](../src/tools/tool_agent.c:318) | **keep** |
+
+No non-source references (Makefile, tests, docs) depend on these symbols.
+
+## Risks
+
+Very low. Both functions carry `__attribute__((unused))` so they are not linked into any runtime path. The only failure modes are accidental deletion of something still live, which the scope analysis above rules out.
+
+## Verification Strategy
+
+1. Clean build with `make` — must succeed with no new warnings.
+2. Existing tests under [`tests/`](../tests/) pass (`python tests/run_tests.py` or the project's usual invocation).
+3. Manual sanity check: start an agent, send a DM, confirm normal reply — no regression, since the deleted code was never on the hot path.

+# Startup Failure Admin DM Notification (original plan)
+
+## Goal
+
+When the agent fails to start, send a best-effort encrypted DM to the administrator
+describing which startup step failed and why, so the operator learns about the failure
+without having to SSH in and read `journalctl`.
+
+This directly addresses the real-world incident on VM410 where both `didactyl.service`
+and `simon.service` were stuck restart-looping at startup step 14
+(`Subscribe self-skill cache: failed (no skill events found after EOSE)`) and silently
+stopped answering DMs.
+
+## Background / Code References
+
+- Startup is a linear checklist in [`main()`](src/main.c:1012). Each step uses helpers:
+  - [`startup_step_begin()`](src/main.c:303)
+  - [`startup_step_ok()`](src/main.c:309)
+  - [`startup_step_fail()`](src/main.c:320)
+- On any fatal failure, the current pattern is:
+  `startup_step_fail(...)` -> `fprintf(stderr, ...)` -> cleanup calls -> `return 1;`
+  (e.g. the step-14 self-skill abort at [`src/main.c:1520`](src/main.c:1520)).
+- The success path already sends an admin "started up" DM at
+  [`src/main.c:1663`](src/main.c:1663) via
+  [`nostr_handler_send_dm_auto()`](src/nostr_handler.c:3264).
+- DM delivery requires (see [`nostr_handler_send_dm_with_role()`](src/nostr_handler.c:3133)):
+  - `g_cfg` and `g_pool` set (relay pool initialized),
+  - at least one **connected** relay (otherwise the kind-4 event is dropped:
+    "kind 4 event not queued: no connected relays" at [`src/nostr_handler.c:3203`](src/nostr_handler.c:3203)),
+  - a valid `cfg.admin.pubkey` (validated at step 4, [`src/main.c:1310`](src/main.c:1310)),
+  - the private key derived (always done before the checklist).
+
+### Delivery-window reality
+
+A failure DM is only *deliverable* from roughly step 11 onward (relay pool created +
+relays connected + admin known). The step-14 failure we actually hit is inside that
+window, so it will be delivered. Earlier failures (bad nsec, missing admin, LLM config,
+no relay connection) have no working channel; per decision, those are **logged only**
+(best-effort, no blocking retries).
+
+## Design Decision (confirmed)
+
+**Best-effort only.** Attempt the failure DM whenever relays + admin are available; if
+the relay pool isn't connected or admin pubkey is unknown, skip the DM and rely on
+existing stderr/journal logging. No blocking retry loop, no self-healing of the
+underlying failure (that can be a separate plan).
+
+## Approach
+
+Add a single helper that builds and sends the failure DM, then call it from every fatal
+startup-abort site (the points that currently do `startup_step_fail(...) ... return 1;`).
+
+### 1. New helper in [`src/main.c`](src/main.c)
+
+Add a static function near the other startup helpers (after
+[`startup_step_fail()`](src/main.c:320)):
+
+```c
+static void notify_admin_startup_failure(const didactyl_config_t* cfg,
+                                         int step,
+                                         const char* label,
+                                         const char* detail);
+```
+
+Behavior:
+- Guard clauses (skip + DEBUG_WARN if any precondition is missing):
+  - `cfg == NULL` or `cfg->admin.pubkey[0] == '\0'` -> log "admin unknown; cannot notify".
+  - `nostr_handler_connected_relay_count() <= 0` -> log "no connected relay; cannot notify".
+- Build a concise human-readable message, e.g.:
+  ```
+  <DisplayName> FAILED to start at <YYYY-MM-DD HH:MM:SS>.
+  Startup step [14] Subscribe self-skill cache failed: no skill events found after EOSE.
+  Version <X>. Connected relays: <n>/<m>. The agent is NOT online and will not answer DMs until fixed.
+  ```
+  - Reuse `nostr_handler_get_startup_display_name()` and `DIDACTYL_VERSION` exactly like
+    the success DM at [`src/main.c:1645`](src/main.c:1645) for naming/version consistency.
+  - Include `step`, `label`, and `detail` so each failure site is self-describing.
+- Send via `nostr_handler_send_dm_auto(cfg->admin.pubkey, msg)`; if it returns non-zero,
+  `DEBUG_WARN` that the failure DM could not be delivered (do not change the exit code).
+- Pump the poll loop briefly after sending so the async publish can flush before process
+  exit: call `nostr_handler_poll(...)` a few times (e.g. ~300--500 ms total) so the
+  queued kind-4 event is actually written to the relay sockets before cleanup/`return 1`.
+  (Without this, async publish may be discarded on immediate exit.)
+
+### 2. Wire the helper into fatal abort sites
+
+For each fatal `startup_step_fail(...)` that ends in `return 1;`, insert a call to
+`notify_admin_startup_failure(&cfg, <step>, "<label>", "<detail>")` immediately after the
+`startup_step_fail(...)` line and before the cleanup/`return 1`.
+
+Priority sites (inside the deliverable window — relay pool up + admin known):
+- Step 11 — discover self relay list failures
+  ([`src/main.c:1420`](src/main.c:1420), [`src/main.c:1437`](src/main.c:1437)).
+- Step 14 — self-skill cache failures (the incident we hit):
+  - subscribe failed ([`src/main.c:1481`](src/main.c:1481)),
+  - EOSE timeout ([`src/main.c:1496`](src/main.c:1496)),
+  - no skill events after EOSE ([`src/main.c:1521`](src/main.c:1521)).
+- Step 15 — Subscribe DMs failed ([`src/main.c:1552`](src/main.c:1552)).
+
+Earlier-window sites (relay/admin may not be ready — helper will self-skip and just log,
+but we still call it uniformly for completeness):
+- Step 1/3/4/5/6/7/8/9 fatal aborts. The helper's guard clauses make these safe no-ops
+  when delivery isn't possible.
+
+Keep the existing `fprintf(stderr, ...)` and cleanup unchanged; the DM is purely additive
+and must never alter the exit code or cleanup ordering.
+
+### 3. Message size / safety
+
+- Use a fixed stack buffer (e.g. `char msg[768];`) like the success DM at
+  [`src/main.c:1644`](src/main.c:1644).
+- `snprintf` with truncation is acceptable; `detail` strings are short and controlled.
+
+## Out of Scope
+
+- No blocking retry / wait-for-relay loop (explicitly declined).
+- No auto-remediation of the step-14 self-skill cause (e.g. auto-publishing the default
+  skill). Tracked separately if desired.
+- No change to `deploy_lt.sh` post-deploy health checks (could be a follow-up: have the
+  deploy script verify each service reaches `READY` after restart).
+
+## Verification
+
+1. Build the static binary (`build_static.sh`) and confirm no warnings.
+2. Local reproduction of step-14 failure: run an `--nsec`-only agent for an identity that
+   has connected relays but **no** published skill events, confirm:
+   - startup still aborts with exit code 1 (unchanged behavior),
+   - the admin receives a DM naming step 14 and the "no skill events found after EOSE"
+     detail.
+3. Negative case: kill relay connectivity (or use an unreachable relay) and confirm the
+   helper logs "no connected relay; cannot notify" and does not crash or hang.
+4. Confirm the success-path startup DM at [`src/main.c:1663`](src/main.c:1663) is
+   unaffected.
+5. Deploy to VM410, restart `didactyl.service` / `simon.service`, and confirm the admin
+   npub receives the failure DM while the skill events are still missing; then publish a
+   skill and confirm normal `READY` + startup DM resumes.
+
+---
+
+# Follow-up: Throttling + Descriptive Failure DM
+
+## Problems observed in production
+
+1. **DM flood.** With `Restart=on-failure` / `RestartSec=10`, the step-14 failure recurs
+   on every restart and the agent reaches the deliverable window each time, so the admin
+   gets a fresh failure DM every ~25s indefinitely (confirmed in the live message box).
+2. **Insufficient detail.** The current message names the step + detail, but not which
+   relays were attempted, whether each connected, nor which event kinds were required.
+
+## Decisions (confirmed with user)
+
+- **Throttle semantics:** send exactly once per failure type (keyed by step) until the
+  agent next starts successfully. The marker is cleared on `READY`. No periodic
+  reminders. A different failing step is a different "type" and notifies once.
+- **Descriptive content:** include the attempted relay list with per-relay connect state,
+  and the event kinds that step 14 needs (31123 / 31124 skill events; 10123 adoption list).
+
+## Part A -- Throttle / de-duplicate via on-disk marker
+
+### Marker file location (systemd-sandbox safe)
+
+- The unit runs with `WorkingDirectory=/home/<user>` and (hardened variant)
+  `ReadWritePaths=/home/<user>`, so only the agent home is writable.
+- `cfg.tools.shell.working_directory` defaults to `"."` (see
+  [`config.c`](src/config.c:1459)), which resolves to the home dir at runtime.
+- Use a hidden marker in the working directory: `./.didactyl_startup_failure`.
+  - For `didactyl` -> `/home/didactyl/.didactyl_startup_failure`
+  - For `simon` -> `/home/simon/.didactyl_startup_failure`
+  - Both inside the writable `ReadWritePaths`, so writes succeed under the sandbox.
+- Resolve the directory the same way the local-file tools do: prefer
+  `cfg->tools.shell.working_directory` when non-empty, else `"."`
+  (mirror [`tool_local.c`](src/tools/tool_local.c:49)).
+
+### Marker contents
+
+Plain text, one record, easy to parse and inspect manually:
+
+- `step=14`
+- `label=Subscribe self-skill cache`
+- `detail=no skill events found after EOSE`
+- `last_sent_epoch=1781314692`
+
+(Only `step` is strictly needed for the de-dup key; the rest aids debugging.)
+
+### New helpers in [`src/main.c`](src/main.c)
+
+Add small static helpers near
+[`notify_admin_startup_failure()`](src/main.c:331):
+
+- `startup_failure_marker_path(cfg, out, out_size)` -- builds
+  `<workdir>/.didactyl_startup_failure`.
+- `startup_failure_already_notified(cfg, step)` -- returns 1 if the marker exists AND its
+  `step=` matches the current `step` (suppress); 0 otherwise (allow). Missing/unreadable
+  marker -> 0 (allow).
+- `startup_failure_marker_write(cfg, step, label, detail)` -- writes/overwrites the marker
+  after an attempted send.
+- `startup_failure_marker_clear(cfg)` -- `remove()` the marker; ignore ENOENT.
+
+### Wiring
+
+- In [`notify_admin_startup_failure()`](src/main.c:331): after the existing guard
+  clauses (config/admin/relay), check `startup_failure_already_notified(cfg, step)`.
+  If it returns 1, log a DEBUG_INFO suppression line and return without sending.
+  - On a successful send, call `startup_failure_marker_write(cfg, step, label, detail)`.
+  - If the same step keeps failing, only the first restart in the episode sends a DM;
+    subsequent restarts find the matching marker and stay silent.
+  - If a different step fails later, the `step=` mismatch allows exactly one new DM and
+    rewrites the marker with the new step.
+- On the success path, clear the marker so the next failure episode notifies again. Add
+  `startup_failure_marker_clear(&cfg);` next to the READY success DM at
+  [`src/main.c:1663`](src/main.c:1663).
+
+### Edge cases
+
+- Marker write failure (e.g. read-only FS): log DEBUG_WARN and continue. Worst case we
+  fall back to current behavior (may re-send on next restart) -- acceptable, never fatal.
+- Two services share the binary but use different home dirs, so markers never collide.
+
+## Part B -- Descriptive failure message
+
+Enhance the message built in
+[`notify_admin_startup_failure()`](src/main.c:331) to append:
+
+1. **Attempted relays + per-relay state.** Add a compact accessor to the nostr handler:
+   - New `nostr_handler_relay_state_summary(void)` in
+     [`nostr_handler.c`](src/nostr_handler.c) / [`nostr_handler.h`](src/nostr_handler.h)
+     returning a caller-freed compact string like
+     `relay.laantungir.net=connected; relay.damus.io=connected; relay.primal.net=connecting`.
+   - Implement by reusing the existing loop over `g_cfg->relays[]` +
+     `nostr_relay_pool_get_relay_status()` + `relay_status_str()` (patterns at
+     [`src/nostr_handler.c:3183`](src/nostr_handler.c:3183) and
+     [`src/nostr_handler.c:419`](src/nostr_handler.c:419)).
+   - Preferred over embedding raw JSON from
+     [`nostr_handler_relay_status_json()`](src/nostr_handler.c:3971) to keep the DM short.
+2. **Needed event kinds (step-specific).** For step 14 append a fixed clause naming the
+   required events: kind 31123/31124 (skills) and kind 10123 (adoption list). Implement as
+   a small `startup_step_needed_events(step)` lookup in [`src/main.c`](src/main.c) that
+   returns a clause for known steps (14, 11, ...) and empty for others.
+
+### Resulting message shape (example)
+
+- `Didactyl FAILED to start at 2026-06-13 10:38:13.`
+- `Startup step [14] Subscribe self-skill cache failed: no skill events found after EOSE.`
+- `Version v0.2.48. Connected relays: 3/3.`
+- `Relays: relay.laantungir.net=connected; relay.damus.io=connected; relay.primal.net=connected.`
+- `Needed events: kind 31123/31124 (skills) and kind 10123 (adoption list) for this agent's pubkey.`
+- `The agent is NOT online and will not answer DMs until fixed.`
+
+Keep within the existing `failure_dm` buffer (bump to ~1536 if needed); `snprintf`
+truncation remains safe.
+
+## Implementation order
+
+1. Add `nostr_handler_relay_state_summary()` to handler `.c`/`.h`.
+2. Add marker helpers + `startup_step_needed_events()` to [`src/main.c`](src/main.c).
+3. Update [`notify_admin_startup_failure()`](src/main.c:331): de-dup check, richer
+   message, marker write on send.
+4. Add `startup_failure_marker_clear(&cfg)` on the READY success path
+   ([`src/main.c:1663`](src/main.c:1663)).
+5. Build (`make`), then `build_static.sh`, deploy, verify.
+
+## Verification (follow-up)
+
+1. **Throttle:** reproduce step-14 failure; confirm exactly one DM on the first failing
+   restart and no further DMs across subsequent restart-loop iterations (journal shows a
+   suppression line).
+2. **Clear-on-success:** publish a skill so startup reaches `READY`; confirm marker is
+   removed and the normal startup DM is sent.
+3. **Re-arm:** break startup again and confirm a single new DM is delivered.
+4. **Descriptive content:** confirm the DM includes the per-relay state line and the
+   needed-events clause.
+5. **Sandbox write:** on VM410 confirm the marker is created at
+   `/home/didactyl/.didactyl_startup_failure` (and `/home/simon/...`) without permission
+   errors under the systemd sandbox.

+# Full n_signer Transport Support in the Setup Wizard
+
+## Context
+
+`n_signer` (upgraded to v0.1.5) now exposes four transports and a new
+`nostr_mine_event` verb. `nostr_core_lib` (v0.6.6, the client lib didactyl links
+against) already exposes all four transport factories and discovery helpers, but
+didactyl's interactive setup wizard and config/main wiring only recognize
+`nsigner_unix` and `nsigner_tcp`. The existing-agent recovery path still
+requires an nsec and uses raw-key NIP-44, which defeats the point of remote
+signer modes.
+
+This plan closes those gaps so an operator can stand up a new agent or recover
+an existing one using any n_signer transport, with the nsec never entering the
+agent process.
+
+## Current State (verified)
+
+- `nostr_core_lib/nostr_core/nostr_signer.h` exposes:
+  - `nostr_signer_nsigner_unix`, `nostr_signer_nsigner_tcp`,
+    `nostr_signer_nsigner_serial`, `nostr_signer_nsigner_fds`
+  - `nostr_signer_nsigner_set_auth` (TCP auth envelope)
+- `nostr_core_lib/nostr_core/nsigner_transport.h` exposes:
+  - `nsigner_transport_list_unix` (enumerate `@nsigner*` abstract sockets)
+  - `nsigner_transport_list_serial` (enumerate `/dev/ttyACM*`)
+- `nostr_core_lib/nostr_core/nostr_signer.c` routes the four core verbs
+  (get_public_key, sign_event, nip04/nip44 encrypt/decrypt) through
+  `nostr_signer_t` for all backends. **`nostr_mine_event` is NOT wired.**
+- `src/config.h` `signer_config_t` has fields for `mode`, `socket_name`,
+  `role`, `timeout_ms`, `auth_privkey_hex`, `tcp_host`, `tcp_port`,
+  `emergency_local_nsec`. **No serial device or fds fields.**
+- `src/config.c` `signer_mode_is_known()` / `signer_mode_is_remote()` only
+  accept `local`, `nsigner_unix`, `nsigner_tcp`.
+- `src/main.c` `apply_signer_overrides()` and `construct_signer()` only handle
+  `local`, `nsigner_unix`, `nsigner_tcp`.
+- `src/setup_wizard.c` `new_agent_identity_step()` option `s` hardcodes
+  `nsigner_unix`, prompts for socket/role/timeout, does a connectivity check,
+  and offers no auto-discovery or TCP/serial/fds choice.
+- `src/setup_wizard.c` `existing_agent_flow()` requires an nsec and uses
+  `nostr_nip44_decrypt`/`nostr_nip44_encrypt` with the raw private key for
+  kind-30078 config recovery (Phase 3 item 13 DEFERRED notes).
+- `src/setup_wizard.c` `install_system_service_with_dedicated_user()` builds
+  `key_args` for `nsigner_unix` and `nsigner_tcp` only.

+
+## Changes by File
+
+### 1. `src/config.h` — extend `signer_config_t`
+
+- Update the `mode` comment to list all five modes:
+  `local | nsigner_unix | nsigner_tcp | nsigner_serial | nsigner_fds`.
+- Add fields:
+  - `char serial_device[OW_MAX_URL_LEN]` — path for `nsigner_serial`.
+  - `int fds_read_fd`, `int fds_write_fd` — for `nsigner_fds` (CLI-only; not
+    persisted to genesis since fds are runtime-only).
+- Add a new `OW_MAX_SIGNER_DEVICE_LEN` constant (reuse `OW_MAX_URL_LEN`).
+
+### 2. `src/config.c` — accept the new modes
+
+- `signer_mode_is_known()`: add `nsigner_serial`, `nsigner_fds`.
+- `signer_mode_is_remote()`: add `nsigner_serial`, `nsigner_fds`.
+- `parse_signer_config()`: parse `serial_device` string. Do NOT parse
+  `fds_read_fd`/`fds_write_fd` from JSON (they are CLI-only); document this.
+- Update the error message string to list all five modes.
+- `config_set_defaults()` (signer block): leave `mode="local"`, zero the new
+  fields.
+
+### 3. `src/main.c` — construct signer for all transports
+
+- `signer_mode_is_remote_local()`: add `nsigner_serial`, `nsigner_fds`.
+- `apply_signer_overrides()`:
+  - Add `--signer-serial <device>` CLI flag → sets mode `nsigner_serial` and
+    `cfg->signer.serial_device`.
+  - Add `--signer-fds <read_fd:write_fd>` CLI flag → sets mode `nsigner_fds`
+    and parses the two fds.
+  - Update the validation block and error message to list all five modes.
+- `construct_signer()`:
+  - Add `nsigner_serial` branch → `nostr_signer_nsigner_serial(
+    cfg->signer.serial_device, role, timeout_ms)`.
+  - Add `nsigner_fds` branch → `nostr_signer_nsigner_fds(
+    cfg->signer.fds_read_fd, cfg->signer.fds_write_fd, role, timeout_ms)`.
+  - Update the "Unknown signer mode" fallback message.
+  - The existing connectivity-check + pubkey-discovery block already works for
+    all remote backends (it calls `nostr_signer_get_public_key`), so no change
+    needed there.
+- Update `print_usage()` help text to document `--signer-serial` and
+  `--signer-fds`.
+
+### 4. `src/setup_wizard.c` — new signer transport picker
+
+Replace the hardcoded `nsigner_unix` block in `new_agent_identity_step()`
+option `s` with a new helper `prompt_signer_transport(cfg)` that:
+
+1. Renders a sub-menu:
+   - `u` nix socket (auto-discover or named)
+   - `t` cp (host:port + optional auth privkey)
+   - `s` erial USB device (auto-discover or path)
+   - `f` d pair (read_fd:write_fd — advanced)
+   - `b` ack
+2. For `u`: call `nsigner_transport_list_unix()` to enumerate running n_signer
+   abstract sockets; if any are found, list them numbered and let the operator
+   pick one or type a custom name; if none found, prompt for a name (empty =
+   auto-discover at boot).
+3. For `t`: prompt `host:port` and an optional 64-char hex auth privkey
+   (echo-suppressed). Store into `cfg->signer.tcp_host/tcp_port/
+   auth_privkey_hex`.
+4. For `s`: call `nsigner_transport_list_serial()` to enumerate
+   `/dev/ttyACM*`; list them and let the operator pick or type a custom path.
+   Store into `cfg->signer.serial_device`.
+5. For `f`: prompt `read_fd:write_fd` (advanced; mainly for qrexec-style
+   deployments). Store into `cfg->signer.fds_read_fd/fds_write_fd`.
+6. Common: prompt `role` (default `main`) and `timeout_ms` (default `15000`).
+7. Set `cfg->signer.mode` to the chosen mode.
+8. Connectivity check: construct an ephemeral `nostr_signer_t*` via the
+   matching factory, call `nostr_signer_get_public_key()` to populate
+   `cfg->keys.public_key_hex`, then `nostr_signer_free()`. On failure, print
+   the error and loop back to the transport picker.
+9. Guard all nsigner_* branches with `#if defined(NOSTR_ENABLE_NSIGNER_CLIENT)`
+   and emit the existing "compiled without n_signer client support" warning
+   otherwise.
+
+Add a parallel entry point to `existing_agent_flow()` so the operator can
+choose "recover via a running n_signer" instead of entering an nsec. See item 5.
+
+### 5. `src/setup_wizard.c` — existing-agent recovery via signer verbs
+
+Refactor `existing_agent_flow()`:
+
+- New first step: choose identity source:
+  - `n` sec (legacy)
+  - `s` ign with a running n_signer (calls `prompt_signer_transport(cfg)`)
+- When the signer path is chosen:
+  - The connectivity check populates `cfg->keys.public_key_hex` from
+    `nostr_signer_get_public_key()`.
+  - Keep the ephemeral signer handle alive for the recovery queries instead
+    of freeing it immediately (pass it through to the recovery helpers).
+- Replace the raw-key NIP-44 decrypt in `fetch_and_decrypt_self_config_wizard()`
+  with a signer-aware variant: when a signer is available, call
+  `nostr_signer_nip44_decrypt(signer, cfg->keys.public_key_hex, ciphertext,
+  &plaintext)`. Fall back to the raw-key path only when `signer == NULL`
+  (local mode). The peer pubkey for self-encrypt is the agent's own pubkey.
+- Replace the raw-key NIP-44 encrypt in
+  `publish_encrypted_self_config_wizard()` the same way.
+- Remove/replace the Phase 3 item 13 DEFERRED comments at those two sites
+  since the signer path is now implemented for the wizard.
+- The `nostr_handler_init(&tmp)` calls in the recovery helpers currently copy
+  the config and re-derive keys; ensure they pick up `cfg->signer` so the
+  handler uses the process signer for its own encrypt/decrypt. (Verify
+  `nostr_handler` already threads the signer through; if not, pass the
+  ephemeral wizard signer via a new `nostr_handler_set_signer()` call for the
+  duration of the recovery queries, then clear it before `cleanup()`.)
+
+### 6. `src/setup_wizard.c` — systemd unit key_args for new modes
+
+In `install_system_service_with_dedicated_user()`, extend the `key_args`
+builder:
+- `nsigner_serial`: `--signer nsigner_serial --signer-serial <device>
+  --signer-role <role> --signer-timeout <ms>`
+- `nsigner_fds`: skip systemd install (fds are runtime-only and cannot be
+  embedded in ExecStart). Print a clear message that fds mode is not
+  installable as a systemd service and the operator must wire the fd-passing
+  themselves (e.g. via a wrapper unit with `Sockets=` or qrexec). Return
+  non-fatal error so the wizard offers "boot now" instead.
+- Update the summary print block (`Signer: %s ...`) to mention serial/fds.
+
+### 7. `src/main.c` — `--signer-serial` / `--signer-fds` arg parsing
+
+Already covered in item 3. Ensure `argv` parsing loop handles the two new
+flags and their values, and that `--signer-fds` parses `read:write` with
+`atoi` validation (both >= 0).
+
+### 8. `nostr_core_lib` — wire `nostr_mine_event` (optional, stretch)
+
+This is a library-side change. If we want didactyl to be able to mine PoW
+events through a remote signer:
+- Add `int nostr_signer_mine_event(nostr_signer_t*, const cJSON* unsigned_event,
+  int difficulty, int threads, int timeout_sec, cJSON** signed_event_out)` to
+  `nostr_signer.h`.
+- Implement the remote branch in `nostr_signer.c` calling
+  `nsigner_client_call(client, "nostr_mine_event", params, &result)` with the
+  options object `{difficulty, threads, timeout_sec}`.
+- Local branch: call the existing `nostr_mine_event` helper in `nip013.c`.
+- This is **not required** for the wizard task; include only if the operator
+  wants PoW through n_signer. Recommend deferring to a follow-up.
+
+### 9. Docs
+
+- Update `docs/GENESIS.md` signer block example to show all five modes and the
+  new `serial_device` field.
+- Update `README.md` quick-start example #5 to mention TCP/serial variants.
+- Add a short section to `docs/CONTEXT.md` (or a new `docs/SIGNER.md`)
+  describing the five modes, when to use each, and the security tradeoff
+  (local keeps nsec in-process; remote modes keep it in n_signer).
+
+## Verification
+
+1. `make deps && make` — must compile cleanly with
+   `-DNOSTR_ENABLE_NSIGNER_CLIENT=1`.
+2. Run `./didactyl --help` — confirm `--signer-serial` and `--signer-fds`
+   appear.
+3. Start a local n_signer on an abstract unix socket; run `./didactyl`
+   (interactive), choose New agent → sign with n_signer → unix → pick the
+   discovered socket → confirm connectivity check prints the pubkey.
+4. Repeat with `--signer-tcp 127.0.0.1:11111` style flow via the wizard TCP
+   option.
+5. Existing-agent flow: with a running n_signer, choose Existing → sign with
+   n_signer → confirm kind-30078 config is decrypted via the signer (no nsec
+   entered). Verify the recovered LLM/admin fields appear.
+6. Negative: kill n_signer mid-wizard → connectivity check fails → wizard
+   loops back to the transport picker.
+7. `nsigner_serial` / `nsigner_fds` modes: validate config load via a
+   genesis file with `signer.mode: "nsigner_serial"` and
+   `serial_device: "/dev/ttyACM0"`; confirm `construct_signer()` attempts the
+   serial factory (will fail without hardware, but the mode must be accepted
+   and reach the factory, not be rejected as "unknown signer mode").
+
+## Out of Scope
+
+- Wiring `nostr_mine_event` into didactyl call sites (only the lib hook in
+  item 8, and only if explicitly requested).
+- Changing the `nostr_handler` signer threading model beyond what the wizard
+  recovery path needs.
+- Windows support for abstract sockets / serial enumeration (Linux-only, as
+  today).
