Untracking the ops docs broke every reference to them. Repoints or removes
those references across README, architecture, ROADMAP, the archive index,
lifecycle TESTING, the hardening plan, and the security docs — pointing at
the issue tracker where a live task list was meant, and dropping the entry
entirely where it only existed to link an internal file.
Also fixes two pre-existing broken links found by validating every relative
link in the tracked docs:
- README linked docs/OPEN_SOURCE_READINESS.md, which never existed
(underscores vs hyphens).
- reticulum-daemon/README.md linked a local Claude session plan at
../../.claude/plans/enchanted-strolling-rocket.md — outside the repo, and
a path that would have shipped publicly pointing at nothing.
All relative links in tracked markdown now resolve: 0 broken.
audit-secrets.sh still 5/5.

With Bitcoin Core's wallet deleted, LND's PSBT round trip is the only
external-signer path Archipelago has, and D-09's key-origin protection moves
from Core descriptors (of which none remain) to the PSBT itself.
Adds `psbt_key_origin_report(&str) -> Result<PsbtKeyOriginReport>` to
lnd/wallet.rs, reporting `input_count`, `inputs_with_key_origin` and
`all_inputs_have_key_origin`. An input counts as carrying key origin when
either its `bip32_derivation` or `tap_key_origins` map is non-empty. A PSBT
with zero inputs reports false rather than vacuous truth. Parsed with the
already-present `bitcoin` and `base64` crates; no dependency added.
`lnd.create-psbt` gains an additive `key_origin` object on its response and a
`tracing::warn!` with the counts when key origin is missing, because that is
the exact condition under which a hardware signer refuses the PSBT. Computed
best-effort: a decode failure degrades to `null`, never to an error, so a
user's send cannot fail because an inspection helper could not parse
something. `handle_lnd_finalize_psbt` and `handle_lnd_create_raw_tx` (which
deliberately auto-signs with LND's hot keys) are untouched.
Three tests, with fixtures built programmatically from the `bitcoin` crate
rather than pasted as opaque base64: with-derivations, without-derivations,
and malformed-is-an-error-not-a-panic.
KEY-03-SIGNING-POSTURE.md gains an honest per-step coverage map of the
fund -> export -> sign offline -> import -> finalize -> broadcast round trip.
Of six steps, only the new inspection has automated coverage; steps 1, 4, 5
and 6 have none, and there is no air-gap transport (no animated QR, no .psbt
file exchange) — export/import is copy-paste of base64. Untested paths are
named as untested.
Records the verdict that decides whether any of this is an air gap: on a
default node an external signer CANNOT meaningfully sign a PSBT from
`lnd.create-psbt`, because LND holds the keys for every input it selects.
Evidence: the PSBT is funded from LND's own wallet; `ensure_wallet_initialized`
creates a full key-holding wallet via /v1/initwallet; the generated lnd.conf
carries no `remotesigner.*` block; and a search of apps/, scripts/,
core/archipelago/src and image-recipe/ for remotesigner/createwatchonly/
nochainbackend returns zero matches. No fleet node is provisioned watch-only.
What ships is PSBT transport, not air-gapped custody — the gap is
provisioning, not plumbing.
Adds the standing honesty statement in its own subsection: Lightning channel,
revocation and HTLC keys are NOT air-gappable at all. They must sign in real
time to answer counterparty commitments; remote signing relocates them to a
hardened host, it does not cool them.
Also adds a status banner to PSBT-SIGNING-ARCHITECTURE.md recording that its
Phase 1 was superseded by deletion rather than delivered, so §0's "single
highest-value change" and §2.1's invariant now read against a code path that
no longer exists. Banner only; §5.4's honesty table is byte-identical.

Watch-only descriptor wallets, external signers, multisig, air-gap transport
and honest LND limits — a spec a future /gsd-plan-phase can consume.
- Names the current gap: bitcoin.rs:203 passes disable_private_keys=false and
bitcoin.rs:229-231 imports wpkh(xprv/...), so Core holds the BIP-84 account
PRIVATE key today. Closing that is Phase 1 and unblocks everything else
- Full Core RPC loop with wallet- vs node-scoped RPCs; analyzepsbt drives UI
- Tier 1 single-sig with mandatory [fingerprint/derivation] key origin; Tier 2
wsh(sortedmulti) on BIP-48; taproot/MuSig2 deferred as UNVERIFIED
- BC-UR v2 primary (fountain-coded, degrades gracefully), BBQr for Coldcard,
file fallback always; animated multi-frame is mandatory, not optional
- LND: channel/revocation/HTLC keys CANNOT be air-gapped; funding tx must
NEVER be self-broadcast (type-level refusal, not a boolean)
- On-chain (PSBT-protectable) vs lightning (necessarily hot) split, with the
exact user-facing sentence the UI must use
- Hot wallet kept as explicitly-secondary with server-enforced limits; safe
path is the DEFAULT, per T1's survivors
- Migration section refuses to over-alarm: the audit found no entropy defect,
so no Archipelago user needs to rotate a seed
- 7 phases with dependencies, candidate requirements, and hardware gating
- Answers two open items in docs/hardware-signer-design.md
- Flags bitcoin-knots:latest as an unpinned tag vs ADR-009
