The accepted interim consequence: **a password-protected +wallet, once migrated, is no longer encrypted under its password at rest** — it +falls back to file-permission protection (`0600`) plus an empty-passphrase vault +until upstream per-secret encryption lands. After migration the wallet no longer +asks for its password to unlock. + +Alex (the Everyday User) does not know what AES-GCM, a vault, or a seam is. Alex +knows two things, and we must speak to exactly those two: **(1) "I set a password +on my wallet"** and **(2) "the app stopped asking me for it."** A change in that +contract that goes unexplained reads as either a bug ("did it forget my +password?") or a breach ("is my wallet open to anyone now?"). Both produce the +support request the persona's success metrics say we must drive to zero. The +disclosure exists to convert a silent, alarming change into an expected, +understood one. + +--- + +## Decision summary + +| # | Item | Decision | +|---|------|----------| +| 1 | Per-wallet password vestigial after migration | Stop asking (`uses_password=false`). One-time per-wallet notice at the migrating unlock. | +| 2 | Single-key per-key passphrase (SEC-002) | Identical treatment to item 1. Same notice family, key-flavored copy. | +| 3 | One-time interim at-rest disclosure | Non-gating, informational. Surfaces *with* the item-1/item-2 notice at the migrating unlock — not at app start, not a separate modal. | +| 4 | SEC-201 (Enter-consume papercut) | Cross-reference only. Not fixed here. Noted that migration runs the modal more often. | + +Design principles applied: **error prevention over recovery** (explain before +the user notices and worries), **progressive disclosure** (one short sentence +the user must read; the technical "why" is one optional click away), and +**calm, actionable tone** (project i18n + error-message rules). + +--- + +## Item 1 — Per-wallet password becomes vestigial + +### What the user experiences + +1. Alex opens a password-protected wallet as always and is prompted to unlock — + **the same unlock modal as today** (`wallet_unlock_popup.rs`). Nothing new + here; the migration needs this one passphrase entry and reuses the existing + flow. (This is the lazy-migration unlock from the plan's Migration section B.) +2. On successful unlock, migration runs inside the decrypt scope and flips + `uses_password=false`. +3. **Immediately after the wallet finishes unlocking**, a single global + info-style notice appears (see Copy A). It is the only new surface the user + sees. +4. On every subsequent open, that wallet **unlocks without a password prompt**. + This is expected because the notice in step 3 told Alex it would happen. + +### Why at the migrating unlock, and once per wallet + +- **At unlock, not app start:** the change is per-wallet and only becomes true at + the moment that specific wallet migrates. A startup banner would fire before + the fact is true, for wallets that may never be opened, and would be generic + noise. Tying the notice to the unlock makes it causally legible: "I just + unlocked, and *this* is what changed about *this* wallet." +- **Once per wallet, not once globally:** Alex may have one wallet with a + password and one without. The fact only applies to the protected one, and only + at its migration. A per-wallet one-time notice (keyed on the same `uses_password` + flip that drives the migration — fire when the flip happens, never again) is + the precise scope. After the flip, `uses_password` is already `false`, so the + notice naturally never re-fires for that wallet. +- **Not gating:** the password is *already* vestigial by the time we could ask + for acknowledgement — the wallet is unlocked and migrated. Gating would be a + speed bump in front of a decision the user cannot change and was made for them + by an approved plan. Informational respects their time (the persona expects + unlock in seconds) while still being honest. + +### Copy A — per-wallet password notice (HD-seed wallet) + +> **Banner type:** `MessageType::Warning` (see note on type below) +> **Surface:** `MessageBanner::set_global`, shown once when this wallet migrates. +> **Details (optional, via `with_details`):** Copy D (the shared "why"). + +``` +"{wallet}" no longer needs its password to open. Your wallet stays on this device, protected by your computer's account. Full password protection will return in a future update. +``` + +- Placeholder: `{wallet}` = the wallet alias/name (`WalletMeta.alias`). One named + placeholder, complete sentences, no fragment concatenation — i18n rule + satisfied. +- No jargon: no "encryption", "vault", "seam", "AES", "at rest". "Protected by + your computer's account" is the truthful, persona-legible rendering of "file + permissions + OS user account" — Alex understands "my computer login keeps my + files private." +- Structure is *what happened* + *current state* + *what to expect*, mirroring + the project error-message rule even though this is not an error. + +--- + +## Item 2 — Single-key per-key passphrase (SEC-002) becomes vestigial + +Treatment is **identical** to item 1: stop prompting for the per-key passphrase, +retain the decode reader for migration, surface the same one-time notice at the +migrating unlock — only the noun changes (an *imported key*, not a *wallet*). + +### Copy B — per-key passphrase notice (imported single key) + +> **Banner type:** `MessageType::Warning` +> **Surface:** `MessageBanner::set_global`, shown once when this key migrates. +> **Details (optional):** Copy D. + +``` +The imported key "{key}" no longer needs its passphrase to use. It stays on this device, protected by your computer's account. Full passphrase protection will return in a future update. +``` + +- Placeholder: `{key}` = the key's user-facing label (the imported-key + alias/address shown in the UI). Single named placeholder. +- "Passphrase" (not "password") matches the term the single-key import flow uses, + so the word the user typed is the word they read back. +- If a wallet and an imported key migrate in the same session, the two notices + are distinct messages (different text), so `set_global`'s text-dedup does not + collapse them — each fact is reported once. + +--- + +## Item 3 — One-time disclosure of the interim at-rest regression + +### Decision: fold the disclosure into the item-1/item-2 notice, non-gating + +The plan's recommended default is "non-gating informational." I am refining +*placement*: rather than a third, free-standing notice (which would mean Alex +sees a password notice **and** a separate security notice and has to reconcile +them), the regression disclosure **is** the item-1/item-2 notice plus its +optional details. Copy A and Copy B already state the regression in +persona-legible terms — "protected by your computer's account" and "full +protection will return." The deeper, honest "why" lives in the details panel +(Copy D) for anyone who clicks, and in the logs. + +### Why non-gating, for the Everyday User specifically + +- **The decision is already made and irreversible for the user.** An "I + understand" gate implies a choice. There is none: the architecture is approved, + migration is automatic, the password is vestigial the instant the wallet + unlocks. A gate in front of a non-choice teaches users to click through + acknowledgements without reading — it *erodes* the weight of future, real + consent dialogs. +- **The persona transacts in seconds and opens the wallet 2–5×/week.** A modal + wall on unlock fights the "unlock in seconds" expectation and, on the second + reading, becomes friction the user resents and dismisses blindly. +- **Honesty without alarm.** We are not hiding the regression — Copy A/B states + it in plain language, Copy D gives the full technical truth one click away, and + it is logged. That satisfies the disclosure obligation without an alarm that + the persona ("did something go wrong with my funds?") would over-read. + +### A note on banner type — why `Warning`, not `Info` + +`message_banner.rs` auto-dismisses `Info`/`Success` on a **short** timer and +`Warning`/`Error` on a **long** timer (`DEFAULT_AUTO_DISMISS_SHORT` vs +`_LONG`). A security-relevant, one-time, must-actually-be-read disclosure should +not vanish on the short timer before Alex has read it. `Warning` gives the longer +dwell and the ⚠ glyph signals "read me, this matters" without the ⛔ alarm of an +error. This is **not** an alarm about a failure — tone in the copy stays calm and +forward-looking ("will return in a future update"). If the implementer finds +`Warning`'s long auto-dismiss still too short for a paragraph the user must read, +prefer a **manually-dismissed** (non-auto) banner over downgrading to `Info`. +The priority order is: *the user reads it once* > *it doesn't nag*. + +### Copy D — shared technical detail (details panel, optional click) + +> **Surface:** `with_details(...)` attached to Copy A and Copy B. Goes to the +> collapsible details panel and the log. This is the one place where slightly +> more precise language is allowed, because it is opt-in for a curious user — but +> it still avoids raw internals. + +``` +This wallet's secrets are now stored in a shared protected location on this device, guarded by your computer's account and file permissions rather than by your wallet password. This is a temporary step while a stronger, built-in protection is being finished. Your keys never leave this device. To keep this wallet extra safe in the meantime, make sure your computer account is password-protected and not shared. +``` + +- This is the only string that gives the user a concrete *self-help* action + ("make sure your computer account is password-protected"), satisfying the + project rule that messages offer something the user can do themselves — even + though the primary banner is informational. It never says "contact support." +- Still no "AES", "vault", "seam", "0600", "empty passphrase". "Shared protected + location," "file permissions," and "computer account" are the truthful, + legible renderings. + +--- + +## Item 4 — SEC-201 (passphrase-modal Enter-consume) — cross-reference only + +**Not designed or fixed here**, per the plan. Recorded so the implementer and QA +hold the context: + +Migration makes the existing unlock modal (`passphrase_modal.rs`) run on **every +protected-wallet unlock that triggers a migration**, and protected wallets are +exactly the ones that migrate lazily. So the known Enter-consume papercut +(SEC-201) becomes **more visible** during the migration window — more users will +hit the modal, possibly hit Enter, during this rollout. This raises the value of +fixing SEC-201 soon, but it is a separate change. If SEC-201 is unfixed when this +ships, expect a modest uptick in Enter-key friction reports concentrated around +first-unlock-after-update; that is the migration surfacing an existing bug, not a +regression introduced by this work. + +--- + +## Surfacing matrix (for the implementer) + +| Trigger | Condition | Copy | Banner type | Once? | Details | +|---|---|---|---|---|---| +| Protected HD wallet finishes lazy migration at unlock | `uses_password` flips `true→false` (HD seed) | Copy A | Warning (or manual-dismiss) | Once per wallet | Copy D | +| Protected imported key finishes lazy migration at unlock | per-key passphrase flips to vestigial | Copy B | Warning (or manual-dismiss) | Once per key | Copy D | +| App start | — | none | — | — | — | +| No-password wallet eager migration | silent (no UX change for the user) | none | — | — | — | + +Notes: +- **Eager (no-password) migrations produce no notice.** Nothing changes from the + user's point of view — the wallet never asked for a password and still doesn't. + Surfacing a security notice there would alarm users about a change they cannot + perceive and that does not affect their (already password-free) wallet. +- **Headless / MCP:** password wallets do not lazily migrate without a GUI unlock, + so none of these notices fire headlessly. No copy is needed for the headless + path; the legacy reader serves silently (per plan Migration section C). +- **"Once" is naturally enforced by the migration itself:** the notice fires on + the `uses_password` flip; after the flip the condition is permanently false, so + re-firing is impossible without a fresh legacy wallet. No separate "seen" flag + is strictly required, though the implementer may add one defensively. + +## i18n compliance checklist (all strings above) + +- [x] Complete sentences, no fragment concatenation. +- [x] Named placeholders only (`{wallet}`, `{key}`), no positional grammar + assumptions. +- [x] No logic embedded in text. +- [x] No jargon in the persona-facing banner copy (A, B); the one slightly + more technical string (D) is opt-in and still jargon-free. +- [x] Each string is a single, extractable translation unit. + +## Persona walk-through (validation) + +Alex, mainnet, one password-protected wallet, updates DET and opens the wallet: + +1. Sees the familiar unlock prompt, types the password. *No surprise.* +2. Wallet opens. A calm ⚠ notice says the wallet won't need its password to open + anymore, it's still on this device protected by the computer account, and full + protection is coming back. *Understood, not alarmed — Alex was told before + noticing the prompt was gone.* +3. (Curious once) clicks details, reads Copy D, makes sure the laptop login is + set. *Given a concrete action; feels in control.* +4. Next week, opens the wallet — no password prompt. *Expected.

(Text-level guard — the compiler already forbids the strongest case via TS-INV-01; this catches a `Vec`-shaped plaintext field that bypasses the type guard.) +- **Expected outcome:** zero matches.

A different scope (different seed_hash) → `Ok(None)` (scope partition). +- **Anti-pattern rejected:** asserting only `is_some()` or `len() == 64`. + +### TS-RT-02 — single-key raw round-trip (unit) + +- **Tier:** unit. **T-task:** T2, T6, T10. **Finding:** bee9c055. +- **Preconditions:** fresh vault; the fixed `SINGLE_KEY_NAMESPACE_BYTES` scope; label `single_key_priv.` (unchanged label scheme). +- **Steps:** `put_secret` raw 32 bytes under the canonical label; `get_secret` it back. +- **Expected outcome:** returned bytes **equal the exact 32 input bytes**; value length is exactly 32 (raw, NOT a `SingleKeyEntry` envelope — assert it does NOT start with `SINGLE_KEY_ENTRY_VERSION` framing). Reading under a foreign `WalletId` → `Ok(None)`. + +### TS-RT-03 — identity-key raw round-trip (unit) + +- **Tier:** unit. **T-task:** T2, T6, T10. **Finding:** bee9c055. +- **Preconditions:** fresh vault; scope `identity.id().to_buffer()`; label `identity_key_priv..`. +- **Steps:** `put_secret` raw 32 bytes; `get_secret`. +- **Expected outcome:** returned bytes equal the 32 input bytes; two distinct `(target, key_id)` labels under the same identity scope do not collide; two identities (distinct scopes) with the same `key_id` do not collide. + +--- + +## 3. Eager migration (no dialog) — no-password seed, unprotected single key, identity key + +Order invariant for ALL eager paths: **vault `put_secret` → sidecar write → legacy delete.** + +### TS-EAGER-01 — no-password HD seed migrates on load (integration, lib) + +- **Tier:** integration (lib). **T-task:** T7, T10. **Finding:** bee9c055. +- **Preconditions:** a legacy `envelope.v1` `StoredSeedEnvelope` with `uses_password == false` (raw 64-byte seed verbatim) present under `seed_hash`; NO raw `seed.raw.v1` label; a matching `WalletMeta` sidecar absent or pre-migration shape. +- **Steps:** run the hydration/load path (`reconstruct_wallet` / seam `get_secret` miss path). +- **Expected outcome (assert ALL):** + 1. raw `seed.raw.v1` now present and `expose_secret()` equals the original 64-byte seed; + 2. `WalletMeta` sidecar written with `uses_password == false`, `xpub_encoded` carried over, hint preserved; + 3. legacy `envelope.v1` label **deleted** (`store.get(scope,"envelope.v1") == None`); + 4. a fresh reload reads via raw seam (legacy reader not consulted — assert by deleting/absence of legacy and successful resolve). +- **Anti-pattern rejected:** asserting only that the wallet "loads" without verifying the four post-conditions. + +### TS-EAGER-02 — unprotected single key migrates (unit) + +- **Tier:** unit. **T-task:** T7, T10. **Finding:** bee9c055. +- **Preconditions:** a legacy `SingleKeyEntry` (`has_passphrase == false`) OR a bare legacy 32-byte raw blob under `single_key_priv.`, with a matching `ImportedKey` sidecar (`has_passphrase == false`). +- **Steps:** run the single-key hydrate/seam-miss migration. +- **Expected outcome:** vault label now holds the **raw 32 bytes** (length 32, no `SingleKeyEntry` framing); `ImportedKey` sidecar present (pubkey-for-locked-render moved into sidecar); legacy framed entry replaced; a subsequent unprotected `sign_with` succeeds and the signature verifies against the WIF-derived pubkey. + +### TS-EAGER-03 — identity key migrates from QI blob (integration, lib) + +- **Tier:** integration (lib). **T-task:** T7, T10. **Finding:** bee9c055. +- **Preconditions:** a stored `QualifiedIdentity` whose `KeyStorage` contains a `PrivateKeyData::Clear` and a `PrivateKeyData::AlwaysClear` (MEDIUM) identity key. +- **Steps:** load the identity through the path that content-detects `Clear`/`AlwaysClear` and migrates. +- **Expected outcome (assert ALL):** + 1. for each migrated key, raw 32 bytes present in the vault under `identity_key_priv..` equal to the original plaintext; + 2. the rewritten QI blob has `PrivateKeyData::InVault` (placeholder) at those slots — **zero** `Clear`/`AlwaysClear` remain (see TS-RESID-01); + 3. `AtWalletDerivationPath` keys are untouched (not migrated — they were never plaintext-at-rest). + +### TS-EAGER-04 — eager migration is idempotent (unit) + +- **Tier:** unit. **T-task:** T7, T10. **Finding:** R-MIGRATION-CRASH. +- **Preconditions:** as TS-EAGER-01/02. +- **Steps:** run the migration twice (second run sees raw present, legacy already gone). +- **Expected outcome:** second run is a no-op success; raw value byte-identical after both runs; no error; legacy stays absent. (`SecretStore::set` upserts identical bytes — re-running must not corrupt or duplicate.) + +--- + +## 4. Crash-safety (R-MIGRATION-CRASH) + +### TS-CRASH-01 — crash AFTER vault+sidecar, BEFORE legacy delete → recoverable (unit) + +- **Tier:** unit. **T-task:** T7, T10. +- **Preconditions:** simulate a partial migration: raw `seed.raw.v1` present AND legacy `envelope.v1` STILL present (the legal mid-migration state). +- **Steps:** run the loader. +- **Expected outcome:** loader **prefers raw** (precedence raw > legacy), serves the raw seed, and the leftover legacy is treated as deletable (deleted on this pass). Resolve succeeds; no key loss; no `SecretSeamMissing`. + +### TS-CRASH-02 — never reach raw-missing-legacy-deleted (unit) + +- **Tier:** unit. **T-task:** T7, T10. +- **Preconditions:** assert the ordering contract structurally: a migration step that writes raw then deletes legacy must NOT delete legacy if the raw `put_secret` returned `Err`. +- **Steps:** inject a `put_secret` failure (vault error double / read-only store) and run one migration step. +- **Expected outcome:** legacy `envelope.v1` is **still present** after the failed step (delete was not reached); the step surfaces a typed error; a later retry can still recover the seed from legacy. Proves keys are never lost on a mid-write fault. + +--- + +## 5. Lazy migration (password wallet) via the existing unlock dialog (R-PROMPT-BOUNDARY) + +### TS-LAZY-01 — unlock migrates a protected HD wallet to raw (integration, lib) + +- **Tier:** integration (lib). **T-task:** T7, T10. **Finding:** bee9c055 / R-PROMPT-BOUNDARY. +- **Template:** `wallet_lifecycle.rs::protected_wallet_registers_upstream_on_unlock_without_restart` (offline context + `seed_legacy_protected_hd_wallet_row` + `handle_wallet_unlocked(&wallet_arc, Some(passphrase))`). +- **Preconditions:** a legacy PROTECTED `envelope.v1` (`uses_password == true`, AES-GCM ciphertext) staged; NO raw label; `WalletMeta.uses_password == true` (or derived from legacy). +- **Steps:** + 1. hydrate (wallet locked, not migrated, `uses_password` still true); + 2. `wallet_seed.open(passphrase)` then `ctx.handle_wallet_unlocked(&wallet_arc, Some(passphrase))` — the single existing unlock gesture, routed through `promote_hd_seed_with_passphrase`. +- **Expected outcome (assert ALL):** + 1. legacy envelope decrypted with the supplied passphrase inside the borrowed `Zeroizing` scope; + 2. raw `seed.raw.v1` written, `expose_secret()` equals the true 64-byte seed; + 3. `WalletMeta.uses_password` flipped to **`false`**; + 4. legacy `envelope.v1` deleted; + 5. exactly **one** prompt's-worth of passphrase use — the unlock the user already performs (no second/out-of-band prompt). + +### TS-LAZY-02 — second unlock is prompt-free after migration (integration, lib) + +- **Tier:** integration (lib). **T-task:** T7, T10. **Finding:** R-PROMPT-BOUNDARY. +- **Preconditions:** state left by TS-LAZY-01 (raw present, `uses_password == false`). +- **Steps:** drive a subsequent secret resolve for the same seed scope through `SecretAccess::with_secret` with a `TestPrompt::never()`. +- **Expected outcome:** resolve succeeds via the unprotected fast-path; `ask_count() == 0`; `can_resolve_without_prompt(scope) == true`; `scope_has_passphrase` now reads `false` from `WalletMeta`. + +### TS-LAZY-03 — single-key protected lazy migration via chokepoint (unit) + +- **Tier:** unit. **T-task:** T7, T10. **Finding:** bee9c055. +- **Template:** `single_key.rs::sec_002_protected_sign_via_chokepoint` (import protected, `SecretAccess::with_secret(SingleKey)` with `ScriptedAnswer`). +- **Preconditions:** a legacy protected `SingleKeyEntry` (`has_passphrase == true`) and matching sidecar (`has_passphrase == true`). +- **Steps:** drive `with_secret(SingleKey{addr})` with the correct passphrase (one `ScriptedAnswer::once`). +- **Expected outcome:** the legacy entry is decrypted JIT; inside that scope the raw 32 bytes are re-stored via the seam; `ImportedKey.has_passphrase` flipped to `false`; legacy framed entry deleted; a subsequent `with_secret` with `TestPrompt::never()` resolves the SAME key bytes prompt-free, and the recovered bytes equal the WIF plaintext. + +### TS-LAZY-KIT-01 — the unlock modal renders once for the migration path (kittest) + +- **Tier:** kittest. **T-task:** T7. **Finding:** R-PROMPT-BOUNDARY / R-SEC-201. +- **Template:** `tests/kittest/secret_prompt.rs` (`passphrase_modal` harness). +- **Preconditions:** the passphrase modal chrome unchanged. +- **Steps:** render the modal once; assert body/hint/submit/cancel render; submit a passphrase. +- **Expected outcome:** the migration reuses the existing single unlock modal (no new modal type, no second modal). This is a surface-contract check only — migration logic is covered by TS-LAZY-01/03. (Cross-reference SEC-201 Enter-consume: do NOT fix here; note migration runs the modal more often.) + +--- + +## 6. Legacy-format read during transition + +### TS-LEGACY-01 — HD legacy envelope served when raw absent (unit) + +- **Tier:** unit. **T-task:** T3, T6, T10. **Finding:** R-MIGRATION-CRASH. +- **Preconditions:** ONLY a legacy `envelope.v1` (no raw label); `uses_password == false` (so no prompt needed for the read assertion). +- **Steps:** call the seam-first / legacy-fallback read path (`decrypt_jit` HdSeed, or the retained `legacy_envelope_get`). +- **Expected outcome:** the 64-byte seed is recovered from the legacy reader and equals the original; the retained legacy decode path is exercised (not an error). For a `uses_password == true` legacy entry, supplying the correct passphrase recovers the seed (the retained AES-GCM reader still functions). + +### TS-LEGACY-02 — single-key legacy entry served when raw absent (unit) + +- **Tier:** unit. **T-task:** T3, T6, T10. **Finding:** R-MIGRATION-CRASH. +- **Preconditions:** ONLY a legacy `SingleKeyEntry` (versioned framed form) OR bare 32-byte legacy blob; no raw migration yet. +- **Steps:** read via the seam-first / `SingleKeyEntry::decode` fallback. +- **Expected outcome:** the retained `SingleKeyEntry::decode` reader returns the entry; an unprotected legacy entry signs without a passphrase; a protected one routes through the chokepoint. Confirms the decode-only retained reader still works during transition. + +--- + +## 7. Headless / `NullSecretPrompt` + +### TS-HEADLESS-01 — password wallet served by legacy reader, no prompt, no failure (integration, lib) + +- **Tier:** integration (lib). **T-task:** T7, T10. **Finding:** R-HEADLESS-SPLIT. +- **Preconditions:** a legacy PROTECTED `envelope.v1` (`uses_password == true`); `SecretAccess` built with `NullSecretPrompt`. +- **Steps:** attempt a secret resolve that requires the passphrase for that scope. +- **Expected outcome:** resolve fails with `TaskError::SecretPromptUnavailable` (NOT a panic, NOT `SecretPromptCancelled`); the wallet stays on the legacy reader; `WalletMeta.uses_password` is **still true** (no headless migration); legacy `envelope.v1` is **still present** (not deleted); raw `seed.raw.v1` is **still absent**. Matches the existing `null_prompt_on_protected_scope_yields_unavailable` shape, extended with the no-migration post-conditions. + +### TS-HEADLESS-02 — no eager/lazy migration of a protected wallet headless (integration, lib) + +- **Tier:** integration (lib). **T-task:** T7, T10. **Finding:** R-HEADLESS-SPLIT. +- **Preconditions:** as TS-HEADLESS-01; run the full headless load/hydration path. +- **Steps:** load + (attempt) migration headlessly; then re-inspect storage. +- **Expected outcome:** storage is byte-for-byte unchanged for the protected wallet (legacy present, raw absent, `uses_password == true`). A **no-password** wallet and identity keys in the SAME headless load DO migrate eagerly (assert their raw labels appear) — proving the split is exactly "protected ⇒ deferred, unprotected ⇒ eager", not "headless ⇒ never migrate". + +--- + +## 8. Identity residency — only `InVault` (R-INVARIANT / bee9c055) + +### TS-RESID-01 — a loaded identity has only `InVault`, never Clear/AlwaysClear (unit) + +- **Tier:** unit. **T-task:** T1, T7, T10. **Finding:** bee9c055. +- **Preconditions:** an identity migrated per TS-EAGER-03 (or loaded post-migration). +- **Steps:** iterate `KeyStorage.private_keys`. +- **Expected outcome:** every entry that previously carried plaintext is now `PrivateKeyData::InVault`; assert **zero** `Clear` and **zero** `AlwaysClear` variants remain anywhere in the `KeyStorage`. `AtWalletDerivationPath` (wallet-derived) entries are permitted and unchanged. Keys are never resident in memory as plaintext. + +### TS-RESID-02 — old QI blob (discriminants 0–3) still decodes after appending `InVault` at index 4 (unit) + +- **Tier:** unit. **T-task:** T1, T10. **Finding:** bee9c055. +- **Preconditions:** a bincode blob encoded BEFORE `InVault` was added (variants Clear=0/AlwaysClear=... per current order: `AlwaysClear, Clear, Encrypted, AtWalletDerivationPath`; `InVault` appended last as index 4). +- **Steps:** decode the legacy blob into the new `PrivateKeyData` enum. +- **Expected outcome:** decodes successfully and yields the original variant — appending `InVault` at the highest index must not shift discriminants 0–3. (Guards the bincode-discriminant trap called out as R in the design.) + +--- + +## 9. On-disk no-leak (hex AND decimal-array) + +### TS-NOLEAK-01 — seam vault blob contains no raw secret (unit) + +- **Tier:** unit. **T-task:** T2, T10. **Finding:** bee9c055. +- **Preconditions:** raw secret stored via the seam for each class (seed, single key, identity key). +- **Steps:** read the on-disk vault file bytes (the `secrets.pwsvault` file), render as a string/byte search. +- **Expected outcome:** because the upstream vault encrypts at rest (Argon2id + XChaCha20-Poly1305 file backend), the plaintext appears in **neither** hex **nor** decimal-array form in the on-disk file. Use the promoted `assert_no_leak`. (This asserts the at-rest file, distinct from `get_secret` which legitimately returns plaintext in memory.) +- **Note:** the seam value in memory IS raw plaintext by design — do not assert no-leak on `get_secret`'s return; assert it on the persisted file. + +### TS-NOLEAK-02 — sidecar (`WalletMeta` / `ImportedKey`) contains no secret (unit) + +- **Tier:** unit. **T-task:** T5, T10. **Finding:** bee9c055. +- **Preconditions:** a migrated wallet + imported key with sidecars written. +- **Steps:** serialize each sidecar blob (bincode) and the on-disk `det-app.sqlite` k/v value; search. +- **Expected outcome:** neither sidecar's bytes contain the raw seed/key in hex or decimal-array form. The sidecar holds only non-secret metadata (alias, `uses_password`, hint, xpub, pubkey-for-locked-render). The moved single-key pubkey is the **public** key — assert it IS present (locked-render needs it) and the private key is NOT. + +### TS-NOLEAK-03 — QI blob carries `InVault` markers, never plaintext (unit) + +- **Tier:** unit. **T-task:** T1, T10. **Finding:** bee9c055. +- **Preconditions:** a migrated identity (TS-EAGER-03). +- **Steps:** encode the `QualifiedIdentity` / `KeyStorage` to its persisted bincode blob; search the bytes. +- **Expected outcome:** the identity-key plaintext appears in neither hex nor decimal-array form in the QI blob; the blob encodes `InVault` placeholders for those slots. + +--- + +## 10. Headless identity-key fast-path + +### TS-FAST-01 — identity-key resolve under `NullSecretPrompt` succeeds, no prompt (unit) + +- **Tier:** unit. **T-task:** T3, T7, T10. **Finding:** bee9c055 / R-HEADLESS-SPLIT. +- **Preconditions:** identity key stored raw via the seam (post-migration); `SecretScope::IdentityKey{...}` with `scope_has_passphrase == false`; `SecretAccess` built with `NullSecretPrompt` (or `TestPrompt::never()`). +- **Steps:** call `resolve_private_key_bytes(target, key_id)` (or `with_secret(IdentityKey)`) and sign/derive. +- **Expected outcome:** resolves the raw 32 bytes prompt-free (`ask_count() == 0`, no `SecretPromptUnavailable`); the resolved key signs and the signature verifies against the identity public key. Proves the unprotected fast-path keeps headless/MCP identity signing working and that `async Signer::sign` (verified at `mod.rs:318`) is a free rider on the resolver. + +--- + +## 11. Delete — vault entries (raw labels) + legacy removed + +### TS-DEL-01 — identity removal deletes identity-key vault entries (unit) + +- **Tier:** unit. **T-task:** T7, T10. **Finding:** bee9c055. +- **Preconditions:** an identity with raw identity keys stored under `identity_key_priv..`; `purge_identity_scope` (identity_db.rs:229, called at :621) extended to clear the identity's vault scope. +- **Steps:** delete the identity. +- **Expected outcome:** `get_secret` for every `identity_key_priv.*` label under that identity's scope → `Ok(None)`; any legacy form gone; OTHER identities' vault entries untouched (assert a second identity's key still resolves). No orphaned raw secret survives a delete. + +### TS-DEL-02 — wallet / single-key removal deletes raw + legacy (unit) + +- **Tier:** unit. **T-task:** T6, T10. **Finding:** bee9c055. +- **Preconditions:** a migrated HD wallet (raw `seed.raw.v1`) and a migrated imported key (raw `single_key_priv.`), each with sidecars. +- **Steps:** forget the imported key (`SingleKeyView::forget`) and delete the wallet. +- **Expected outcome:** raw vault label gone; legacy label gone (idempotent delete of both forms); sidecar entry removed; in-memory index cleared. `forget` on an already-removed address remains `Ok(())` (idempotent). A second wallet's secrets are unaffected. + +--- + +## 12. `ClosedSingleKey` redacting Debug (6a2818cd) + +### TS-DBG-01 — `ClosedSingleKey` `{:?}` exposes no raw 32 bytes (unit) + +- **Tier:** unit. **T-task:** T9. **Finding:** 6a2818cd. +- **Preconditions:** a `ClosedSingleKey` populated with a distinctive 32-byte value in `encrypted_private_key` (use the `distinctive_secret()` pattern). +- **Steps:** render `format!("{:?}", closed)` and, transitively, `format!("{:?}", SingleKeyData::Closed(closed))` and a `SingleKeyWallet` holding it. +- **Expected outcome:** via the promoted `assert_no_leak`: the 32 bytes appear in **neither** hex **nor** decimal-array form at any level (the decimal-array check is the one the pre-fix derived `Debug` failed); a redaction marker (`[redacted]` / fingerprint) IS present. Mirrors `ClosedKeyItem` and `PrivateKeyData` redaction. Confirms parents `SingleKeyData`/`SingleKeyWallet` are safe by delegation. + +--- + +## 13. `SecretSeamMissing` surfaced loudly (R-MIGRATION-CRASH) + +### TS-MISS-01 — label in neither raw nor legacy → typed `SecretSeamMissing` (unit) + +- **Tier:** unit. **T-task:** T4, T7, T10. +- **Preconditions:** a wallet/identity/single-key reference whose secret label is present in **neither** raw nor any legacy form (e.g. sidecar exists but both vault forms are gone). +- **Steps:** resolve the secret through the loader/seam-first path. +- **Expected outcome:** `Err(TaskError::SecretSeamMissing)` — a dedicated typed variant (no `String` field per CLAUDE.md error rules), distinct from `WalletNotFound` / `ImportedKeyNotFound` / `SecretDecryptFailed`. **Never** a silent `Ok(None)` that drops a key on the floor. + +### TS-MISS-02 — `SecretSeamMissing` is loud, not silent, on the funds-safety path (unit) + +- **Tier:** unit. **T-task:** T4, T7, T10. +- **Preconditions:** as TS-MISS-01, on a sign/spend path. +- **Steps:** attempt a sign with the missing secret. +- **Expected outcome:** the operation returns `SecretSeamMissing` (or a class-flavored wrapper carrying it as `#[source]`), surfaced to the banner with an actionable message; the failure is observable, not swallowed. Assert the error variant by structural match, never by parsing the message string. + +--- + +## 14. `WalletMeta` schema-gating (R-SCHEMA) + +### TS-META-01 — new `WalletMeta` shape round-trips; old blob detected and migrated (unit) + +- **Tier:** unit. **T-task:** T5. **Finding:** R-SCHEMA. +- **Preconditions:** `WalletMeta` gains `uses_password` + `password_hint`; the change is format-breaking for positional bincode behind the `DetKv` schema envelope. +- **Steps:** + 1. round-trip the NEW shape through bincode (mirror `wallet_meta_round_trips_through_bincode`); + 2. write a blob in the OLD shape (no `uses_password`/`password_hint`), bump/read via the schema-version gate. +- **Expected outcome:** new shape round-trips field-for-field; the OLD blob is detected by the schema byte (NOT silently misread via `#[serde(default)]` alone — the design explicitly forbids relying on that) and content-migrated to the new shape with `uses_password` defaulted correctly. A blob read under a mismatched schema version is rejected/migrated, never positionally misparsed. + +### TS-META-02 — `uses_password`/`password_hint` survive cold-boot (unit) + +- **Tier:** unit. **T-task:** T5. +- **Steps:** write a `WalletMeta` with `uses_password == true` + a hint, drop the in-memory state, re-read. +- **Expected outcome:** both fields recovered exactly; `scope_has_passphrase(HdSeed)` reads them from `WalletMeta` (not the legacy envelope) post-migration. + +--- + +## 15. Zeroize of transient decoded plaintext (f0d946ed) + +### TS-ZERO-01 — legacy-reader transient plaintext is `Zeroizing`/`SecretBytes` (unit) + +- **Tier:** unit. **T-task:** T6, T9. **Finding:** f0d946ed. +- **Preconditions:** the retained legacy readers (`decrypt_hd_seed`, `SingleKeyEntry::decrypt`) and the migration re-store step. +- **Steps:** assert the decoded-plaintext bindings are typed `Zeroizing<[u8; N]>` / `SecretBytes` (compile-level: the function return types already are — assert they are NOT widened to plain `Vec`/`[u8; N]` by the migration code). A confinement test (mirror `sentinel_never_appears_in_error_or_debug`) drives a migration and asserts the sentinel plaintext never appears in any error/Debug surfaced by the path. +- **Expected outcome:** transient plaintext is wrapped; no plain `Vec` copy of a secret escapes the migration scope; sentinel never leaks to error/Debug. Largely subsumed by the seam (`SecretBytes`), this case guards the legacy-reader → seam handoff specifically. + +--- + +## 16. End-to-end signing (network) — out of CI + +### TS-SIGN-E2E-01 — broadcast a testnet state transition from a migrated imported-key identity + +- **Tier:** backend-e2e(network). **T-task:** T7, T8, T11. **Finding:** bee9c055. +- **[FUNDED-TESTNET — OUT OF CI]** — requires `E2E_WALLET_MNEMONIC`, live DAPI/SPV; `#[ignore]`. +- **Preconditions:** an identity whose signing key was migrated to `InVault` raw storage; a funded testnet wallet. +- **Steps:** trigger a cheap state transition (e.g. an identity update or a DPNS preorder) that signs through the async `QualifiedIdentity` `Signer` → `resolve_private_key_bytes` → `with_secret(IdentityKey)`. +- **Expected outcome:** the ST signs via the InVault per-use JIT path and broadcasts successfully; the platform accepts the proof; the key was never resident as plaintext between signs. Confirms the JIT identity-signing free-rider claim against a live network. +- **Manual fallback (if no funded wallet):** the manual checklist in the execution plan (load a pre-existing protected wallet → unlock → confirm migration + sign + neither vault nor sidecar holds raw bytes). Document the skip per CLAUDE.md when infrastructure is unavailable. + +--- + +## Coverage self-audit (gaps the implementer must NOT silently close) + +- **No-serialization guard mechanism is undecided at the dependency level.** `static_assertions` and `trybuild` are NOT in `Cargo.toml`. The preferred zero-dependency mechanism for TS-INV-01 is a `compile_fail` doctest; adding `trybuild` is a Phase-2 call. If the implementer drops the compile-fail case entirely and keeps only the text audit (TS-INV-03), the strongest leg of R-INVARIANT is lost — that is a regression, flag it. +- **The on-disk no-leak cases (TS-NOLEAK-01) depend on the upstream vault actually encrypting at rest.** The accepted interim regression is that the global vault passphrase is empty (deferred `e0a8f4b1`). The XChaCha20-Poly1305 file backend still encrypts under a derived key even with an empty passphrase, so the plaintext should not appear verbatim — but if a future change makes the at-rest format plaintext-equivalent, TS-NOLEAK-01 is the canary. Do not weaken it to "blob != exact in-memory struct". +- **`assert_no_leak` is currently private to `encrypted_key_storage.rs::tests`.** It MUST be promoted to a shared test utility for TS-NOLEAK-01/02/03 and TS-DBG-01. A copy-paste fork is a maintenance finding. +- **TS-INV-03's module list must track the blast-radius table.** A stale list silently shrinks the audit surface. From 9d313b7e8e128afd7dc387a366ea4d4a1a6e0f00 Mon Sep 17 00:00:00 2001 From: Lukasz Klimek <842586+lklimek@users.noreply.github.com> Date: Fri, 19 Jun 2026 17:39:50 +0200 Subject: [PATCH 02/71] feat(wallet-backend): add raw-SecretBytes secret seam + typed errors (T2,T4) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Crikey, here's the one socket every wallet secret will squeeze through. T2 — new wallet_backend/secret_seam.rs: SecretSeam over raw SecretBytes with put_secret/get_secret/delete_secret, a no-encryption pass-through to the upstream vault TODAY. Every put/get body carries the greppable `TODO(per-secret-encryption):` tag so wiring real per-secret encryption later is a localized change. Prompt-free — the passphrase requirement lives only in the retained legacy readers, never here. No-serialization guard mechanism: compile_fail doctests (no new deps — static_assertions/trybuild stay out of Cargo.toml). One asserts a newtype cannot derive Serialize over a SecretBytes; one asserts serde_json::to_string on a SecretBytes is rejected. If upstream ever adds Serialize to SecretBytes these start compiling and the canary fires (TS-INV-01). TS-INV-02 round-trips a SecretBytes through the real signatures (compiler is the assertion). T4 — TaskError variants (no String fields, typed #[source]): SecretSeam, SecretSeamMissing (loud funds-safety miss), IdentityKeyVault, IdentityKeyMissing. Promote the private assert_no_leak (hex + decimal-array) into a shared wallet_backend/leak_test_support.rs so the seam/sidecar/QI/Debug leak cases reuse one impl instead of copy-pasting. TS-NOLEAK-01: the on-disk vault file holds no raw secret in either form. Tests: 6 seam unit + 2 compile-fail doctests, all green.

WalletMeta gains uses_password + password_hint. Because WalletMeta is positional bincode behind the DetKv envelope, #[serde(default)] alone is NOT forward-compatible (R-SCHEMA) — so a real version gate: WALLET_META_VERSION (v2) framed as [version | bincode] at the WalletMetaView boundary, plus a retained decode-only WalletMetaV1. decode_versioned detects v2 / v1-framed / bare-legacy and migrates a v1 blob into v2 (defaults uses_password=false), never positionally misparsing it. The global DetKv SCHEMA_VERSION is deliberately untouched (it governs every payload, not just WalletMeta). TS-META-01 covers all three shapes. ImportedKey gains public_key_bytes (the compressed SEC1 PUBLIC key) so the locked-render cold-boot path can rebuild a protected key's display wallet without the secret — moved out of the SingleKeyEntry vault blob ahead of the raw-seam migration. NON-secret; #[serde(default)] for old entries. write_wallet_meta now carries uses_password/password_hint from the open Wallet; the legacy-table drain (finish_unwire) defaults them (the authoritative flag is read from the envelope at the migrating unlock).

Borrowed-only, zeroizing, never resident — same hygiene as the other kinds. - decrypt_jit is now SEAM-FIRST for all three classes: the raw label wins; the retained legacy reader (decrypt_hd_seed / SingleKeyEntry::decrypt) is the migration fallback for HD seeds and single keys. IdentityKey reads raw via the seam → loud IdentityKeyMissing if absent (never silent). - scope_has_passphrase: a migrated raw secret reports false (the password no longer gates it); only a not-yet-migrated legacy entry can still be protected; IdentityKey is always false → prompt-free fast-path → headless/MCP signing works. - DetSigner treats an IdentityKey plaintext as a raw single key (same secp256k1 shape, no derivation tree). Tests: TS-FAST-01 (identity key resolves prompt-free, ask_count 0, can_resolve_without_prompt true), IdentityKeyMissing is loud, TS-LEGACY-01 (legacy envelope served when raw absent), raw-wins-over-legacy precedence. The pre-existing protected-HD/single-key tests now exercise the legacy fallback.

No DET envelope for the new write paths. - New wallet_backend/identity_key_store.rs: IdentityKeyView with store/get/delete + store_all/delete_all over raw 32 bytes via SecretSeam (scope = identity_id, label identity_key_priv..). NO StoredIdentityKey envelope — the InVault marker in the QI blob is the only on-disk trace. store_all is the migration's vault-first writer (call before the blob rewrite); delete_all backs purge_identity_scope. - WalletSeedView gains set_raw/get_raw/delete_raw (raw 64-byte seed under seed.raw.v1 via the seam) + legacy_envelope_get (retained decode-only reader). - write_seed_envelope now branches: a no-password wallet writes the RAW seed (encrypted_seed_slice() is verbatim the seed); a password wallet keeps the legacy AES-GCM envelope at creation and migrates lazily at unlock (T7). - import_wif_with_passphrase: unprotected import writes RAW 32 bytes under the existing single_key_priv. label (no SingleKeyEntry framing); protected import keeps the legacy SingleKeyEntry (lazy-migrates at unlock). The locked-render pubkey rides in the ImportedKey sidecar (the T5 field). SingleKeyEntry::decode treats a bare 32-byte blob as unprotected, so a raw-written key still rebuilds + opens at cold boot. Tests: identity_key_store round-trip / scope+target isolation / store_all+ delete_all; seed raw round-trip independent of the legacy label; single-key unprotected import is exactly 32 raw bytes (no framing) and signs.

Funds-safety ordering throughout. Resolver (mod.rs): resolve_private_key_bytes gains the InVault route — keyed by is_in_vault/public_key_for, it fetches the raw bytes per-use via with_secret(IdentityKey{...}) (prompt-free). No chokepoint wired ⇒ fail closed (WalletLocked); bytes never resident. EAGER migration on load (dialog-free): - Identity keys (identity_db::migrate_identity_keys_to_vault, run per identity in load_identities_filtered): take_plaintext_for_vault → IdentityKeyView store_all (vault FIRST) → rewrite the QI blob with InVault. Vault-write failure restores the resident plaintext for this session and defers; a blob-rewrite failure is re-detected and retried next load. Idempotent. - No-password HD seeds (hydration::reconstruct_wallet): raw seam wins (precedence raw > legacy); a no-password legacy envelope is re-stored raw (set_raw, vault FIRST) then deleted. reconstruct_from_envelope extracted so the raw and legacy paths share the xpub-decode + build tail. LAZY migration on unlock (one prompt, the unlock the user already does): promote_and_maybe_migrate_hd_seed re-stores the just-decrypted legacy seed raw (set_raw before delete) inside the borrowed Zeroizing scope and reports migrated=true; handle_wallet_unlocked then flips WalletMeta.uses_password=false and shows the one-time disclosure (T8 Copy A/D). Delete: forget_wallet_local_state now deletes BOTH the raw seed and the legacy envelope (a wallet may be in either form) — closes a wipe gap where a migrated no-password seed would survive removal. identity_db.clear_identity_vault_keys drains an identity's raw vault keys on single-delete + devnet sweep. Loud, never silent: a seed in neither form ⇒ TaskError::SecretSeamMissing (was WalletNotFound) on both scope_has_passphrase and decrypt_jit. Tests: TS-EAGER-01/04 (no-pw seed migrates + idempotent), TS-CRASH-01 read (raw wins, legacy cleaned), TS-MISS-01 (SecretSeamMissing loud). Updated 5 wallet_lifecycle removal/clear tests to assert the raw seed (the new at-rest form) in BOTH precondition and post-delete. wallet_lifecycle 38, hydration 10, identity_db 16, encrypted_key_storage 4 — all green.

Two new WalletTasks + handlers, opening with_secret(IdentityKey{...}): - DeriveIdentityKeyForDisplay → derive_identity_key_for_display: fetches the raw key JIT, returns only the WIF (Secret). - SignMessageWithIdentityKey → sign_message_with_identity_key: signs in the backend, returns only the public Base64 envelope. New result variants IdentityKeyForDisplay / IdentityMessageSigned (identity- flavored — carry identity_id/target/key_id, not a meaningless seed_hash). key_info_screen: the InVault arms are now real — "View Private Key" queues DeriveIdentityKeyForDisplay and renders the returned WIF/hex via the existing render_decrypted_key_grid; "Sign" queues SignMessageWithIdentityKey. The degraded placeholders are gone. display_task_result handles both new results. Single-key protected lazy migration + Copy B: verify_passphrase now re-stores the just-decrypted protected entry raw under the same label (upsert replaces the AES-GCM framing) and clears the persistent has_passphrase flag, returning a migrated bool. verify_single_key_passphrase surfaces the one-time per-key disclosure (Copy B — text DISTINCT from the wallet Copy A so set_global's dedup keeps both) on migration. decrypt_jit's sign path also lazy-migrates (migrate_single_key_to_raw + in-memory flag flip) — idempotent defense-in-depth. SingleKeyView::clear_passphrase_flag persists the flip to the sidecar. Tests: TS-LAZY-03 — protected single key migrates via the chokepoint, the vault holds raw 32 bytes after, and a second resolve under a never-prompt host is prompt-free with the WIF-plaintext bytes. secret_access 24 green.

ImportedKey appended public_key_bytes with no legacy reader → old keys vanish from the picker. Fix (one policy for both sibling sidecars): drop the hand-rolled version byte (SEC-003: it could collide with a bincode length varint — a 1/2-char alias). Instead lean on the DetKv schema envelope + try-decode-both: - write the current shape directly (kv.put:: / ::); - on read, try the current shape; on a bincode Decode error (an old blob runs out of bytes for the appended fields) fall back to the legacy shape (WalletMetaV1 / ImportedKeyV1, decode-only) and RE-STORE in the new shape. Order is load-bearing and tested: the 6-field struct CANNOT decode a 4-field blob (runs past end), so "new first, then V1" never mis-promotes. A DetKv schema-version mismatch stays a hard error; only Decode triggers the fallback. Removes the now-dead encode_versioned/decode_versioned/WALLET_META_VERSION (PROJ-002 — the unreachable legacy branch + its overclaiming test are gone; the legacy path is now live via the view and tested end-to-end). Tests: model leg (ts_meta_01) asserts the order-sensitivity + the SEC-003 1/2-char-alias collision case; view legs (old_wallet_meta_blob_*, old_imported_key_blob_*) write an OLD blob exactly as the base branch did, read it back through the view preserving every field, and confirm re-store in the new shape. wallet::meta 3, wallet_meta 13, single_key all green.

QA-002 — migration is vault-FIRST: the persist closure asserts the raw keys are already in the vault and the blob being persisted is InVault-only; the AtWalletDerivationPath key is untouched; zero plaintext remains; idempotent (second run = Nothing). QA-005 — write-fault no-loss (the write half CRASH-01's read half misses): with the vault parent dir chmod'd read-only so store_all fails, the migration restores the resident plaintext keystore byte-for-byte, does NOT call persist, and reports VaultWriteFailed — keys never lost on a mid-write fault. (#[cfg(unix)].) QA-003 — identity-key deletion is scoped + isolated: delete_all over the victim's (target,key_id) set removes its vault keys while a second identity's key under the same (target,key_id) is untouched.

charset=UTF-8 Content-Transfer-Encoding: 8bit PROJ-004 (security): take_plaintext_for_vault now zeroizes the resident Clear/AlwaysClear array BEFORE the InVault overwrite drops it — de-residenting the key is the function's whole purpose, so it must wipe the source, not just the moved-out copy. PROJ-005: IdentityKeyView::store/get/delete now map the generic seam error to the identity-flavored TaskError::IdentityKeyVault (previously a producerless variant), so an identity-key vault failure surfaces with identity-specific banner copy. Wrong-length stays SecretDecryptFailed. QA-DEDUP-01: lift dash_signed_message (the recoverable-envelope builder) from sign_message_with_key.rs to backend_task/wallet/mod.rs as pub(crate); both the wallet-key and identity-key signers now call it instead of two drifting copies. The recovery-header round-trip tests move alongside the shared helper.

Add materialize_master_key_as_clear(): derive the master key's raw bytes from the HD seed through the real with_secret(SecretScope::HdSeed) chokepoint (identity index 0, key 0) and insert_non_encrypted() them as Clear, so the migration carries a genuine plaintext key into the vault as InVault and the JIT signing path produces a signature whose bytes match the on-chain master key. The !taken.is_empty() assertion is unweakened; no signer stub, no mocked broadcast. Stays #[ignore]: the live broadcast additionally needs a funding wallet that derives within its rehydrated window (the e2e funding step hit the known core-wallet gap-window/rehydration limitation, unrelated to the InVault path).

("platform-wallet-secret-protection") hardened upstream `SecretStore::file(path, passphrase)` to reject a blank passphrase (`SecretStoreError::BlankPassphrase`). DET's `open_secret_store` opened the vault with `SecretString::new("")`, so after the repin every AppContext init failed at the secret-store open and 7 secret_seam/secret_access tests broke. Switch to the explicit keyless door `SecretStore::file_unprotected(path)`, which upstream documents for exactly this model: the vault file itself is keyless (at-rest floor = owner-only perms) and per-secret confidentiality comes from Tier-2 object passwords on the individual secrets. Behavior for the Tier-1 baseline is unchanged from the old empty-passphrase open. Restores the green baseline at the fb7953ea pin: build/clippy/fmt clean, the 8 secret_seam/secret_access vault tests pass again.

Crash-safe: re-store upserts before the legacy delete; the scheme probe prefers the new label. - `promote_and_maybe_migrate_hd_seed` no longer downgrades; it reports "no downgrade" so the unlock callsite's `uses_password=false` finalizer never fires — protection is kept and the metadata stays accurate, with no change to `wallet_lifecycle.rs`. - `is_wrong_passphrase` now also catches the upstream `WrongPassword` so a Tier-2 unseal with a bad object password re-prompts instead of aborting. Per-SECRET model: the session cache is plaintext keyed by `SecretScope`, so remembering seed A never satisfies seed B — each prompts and decrypts only with its own password. Tests: lazy re-wrap keeps protection (legacy gone, raw read of a protected seed fails), Tier-2 wrong-password re-ask, and the A/B different-password isolation. 72 secret tests pass; clippy/fmt green.

Protected HD seeds STAY protected (Tier-2 object password); nothing downgrades them to a raw, password-free secret. - `wallet_lifecycle.rs`: remove `finish_lazy_seed_migration` (the `uses_password=false` downgrade flip + the "protection removed" notice) and collapse the two `promote_*` methods into one `promote_hd_seed_with_passphrase` (decrypt + cache) — the lazy re-wrap lives in `decrypt_jit`. The unlock callsite no longer finalizes a downgrade. - `finish_unwire::migrate_wallet_meta`: carry the legacy `wallet.uses_password` / `password_hint` into `WalletMeta` (it was defaulting `false`). The persisted flag is now accurate from cold-start (`true` for a protected wallet) and always agrees with the at-rest scheme — no stale/drift-prone metadata. - `protected_wallet_registers_..._on_unlock` acceptance test rewritten to the keep-protection end-state: after the migrating unlock the seed is Tier-2 (scheme=Protected), a raw read fails, `WalletMeta.uses_password` stays true, and a second resolve prompts for the object password. 1009 lib tests pass; clippy -D warnings + fmt clean.

A protected imported key STAYS protected under its own object password instead of being re-stored raw. - `decrypt_jit` / `scope_has_passphrase` (SingleKey) are scheme-driven (seam `get(None)` → `NeedsPassword` probe): Protected → unseal with the JIT-prompted per-key password; Unprotected → a migrated raw-32 key wins prompt-free, else the not-yet-migrated legacy `SingleKeyEntry` blob's `has_passphrase` decides; the in-band length-32 check disambiguates raw vs legacy-framed. - `migrate_single_key_to_raw` → `migrate_single_key_to_tier2`: lazy re-wrap the just-decrypted protected key to a Tier-2 envelope under the same password (upsert replaces the AES-GCM framing). `has_passphrase` is NOT flipped — protection is kept and the index/persisted flag stay accurate. - `single_key::verify_passphrase` (the unlock-gesture path): re-wraps to Tier-2 instead of downgrading to raw; returns `()` (no migration bool). The `clear_passphrase_flag` finalizer is removed. Downgrade-disclosure machinery retired (Tier-2 keeps protection, nothing to disclose): removed `show_single_key_migration_notice` + the `wallet_migration_notice` / `single_key_migration_notice` / `INTERIM_AT_REST_DETAILS` copy + their re-exports, and the obsolete `tests/kittest/disclosure_banner.rs`. Tests: `ts_lazy_03` rewritten to the keep-protection end-state (vault holds a Tier-2 envelope, password-free read fails, second resolve prompts). 1009 lib tests pass; clippy -D warnings + fmt clean.

The upstream register_wallet (inside create_wallet_from_seed_bytes) inserts into wallet_manager (step A) and into self.wallets (step B) with async work in between (persister.store + load_persisted + initialize). A concurrent caller that lands between A and B sees WalletAlreadyExists from step A, then get_wallet returns None (step B not yet complete) → resolve_registered_wallet returns WalletNotFound. Under CI load this window is reliably hit. Fix: register the wallet BEFORE wiring the backend. register_wallet_upstream finds no backend and returns early without spawning the subtask.

A (BLOCKER): identity write paths no longer serialize plaintext keys. insert/update_local_qualified_identity (and the alias re-encode) now route through encode_identity_blob_vault_first — the write-path twin of the load migration: plaintext keys go into the vault FIRST, the persisted blob carries only InVault placeholders, and a vault-write failure aborts the write (never lands Clear/AlwaysClear bytes in det-app.sqlite). B (HIGH) / C (BLOCKER): cold-boot hydration no longer drops Tier-2-protected wallets. reconstruct_wallet (HD seed) and rebuild_wallet (imported single key) branch on the at-rest SecretScheme before reading the secret. A Protected secret rehydrates CLOSED from the public sidecar (xpub / public_key_bytes) instead of propagating NeedsPassword as fatal, so a keep-protection-migrated wallet stays in the picker across launches. D: the HD Absent-branch legacy-envelope delete is now best-effort (log, don't propagate), matching the Protected branch — a transient delete failure no longer fails an otherwise-successful unlock. E: the eager no-password seed migration wraps the extracted 64-byte seed in Zeroizing so the stack copy wipes on drop. F: resolve_registered_wallet tolerates the registration TOCTOU window with a bounded re-poll before declaring a wallet missing; the fund-routing xpub gate is unchanged. G: present-but-malformed identity-key bytes map to SecretDecryptFailed (with a warn) in both the display and sign tasks, distinct from genuinely-absent IdentityKeyMissing. I/J: refreshed stale doc-comments (single-key has_passphrase, WalletMeta uses_password, wallet_seed_store header) to describe the Tier-2 keep-protection shape, and stripped ephemeral review-finding IDs from secret-path comments. Regression tests cover A, B, and C. <sub>🤖 Co-authored by [Claudius the Magnificent](https://github.com/lklimek/claudius) AI Agent</sub> --- src/backend_task/migration/finish_unwire.rs | 14 +- .../wallet/derive_identity_key_for_display.rs | 10 +- .../wallet/sign_message_with_identity_key.rs | 4 +- src/context/identity_db.rs | 114 ++++++- src/context/wallet_lifecycle.rs | 22 +- .../encrypted_key_storage.rs | 2 +- src/model/single_key.rs | 10 +- src/model/wallet/meta.rs | 12 +- src/wallet_backend/hydration.rs | 191 ++++++++++-- src/wallet_backend/mod.rs | 30 +- src/wallet_backend/secret_access.rs | 17 +- src/wallet_backend/secret_seam.rs | 2 +- src/wallet_backend/single_key.rs | 278 +++++++++++++----- src/wallet_backend/single_key_entry.rs | 7 +- src/wallet_backend/wallet_meta.rs | 6 +- src/wallet_backend/wallet_seed_store.rs | 34 ++- 16 files changed, 602 insertions(+), 151 deletions(-) diff --git a/src/backend_task/migration/finish_unwire.rs b/src/backend_task/migration/finish_unwire.rs index 1b8444d8f..eefe8ab39 100644 --- a/src/backend_task/migration/finish_unwire.rs +++ b/src/backend_task/migration/finish_unwire.rs @@ -745,7 +745,7 @@ const LEGACY_SALT_LEN: usize = 16; /// (12 bytes, see `src/model/wallet/encryption.rs`). const LEGACY_NONCE_LEN: usize = 12; -/// SEC-007 — row-level length guard for the password-related crypto +/// Row-level length guard for the password-related crypto /// fields on a legacy `wallet` row.

Fresh protected single-key imports now seal Tier-2 at import time instead of writing the legacy DET AES-GCM SingleKeyEntry envelope and migrating lazily on first unlock. import_wif_with_passphrase routes the protected branch through the seam's put_secret_protected, so the storage chokepoint is a single shape from import onward. raw_key_bytes and verify_passphrase branch on the at-rest SecretScheme: a Tier-2 key surfaces SingleKeyPassphraseRequired on a direct read and is verified by unsealing (wrong password -> SingleKeyPassphraseIncorrect, no oracle), while the legacy decode + lazy re-wrap path is retained for pre-existing installs. The legacy AES-GCM SingleKeyEntry remains a decode-only reader. sec_002_import_with_passphrase_encrypts_payload tightens to assert SecretScheme::Protected at import; ts_lazy_03 now starts from a directly-written legacy entry so the legacy->Tier-2 migration stays covered. Present-but-malformed identity-key bytes map to a new typed TaskError::IdentityKeyMalformed (jargon-free "stored but unreadable / re-import to refresh") in both the display and sign tasks, replacing the off-domain SecretDecryptFailed ("recovery phrase") message and staying distinct from the genuinely-absent IdentityKeyMissing. migrate_keystore_to_vault and encode_identity_blob_vault_first skip the KeyStorage clone in the steady-state (already-InVault) case via a new KeyStorage::has_plaintext_for_vault probe, so cold-boot load and identity re-saves no longer clone per identity for no benefit. <sub>🤖 Co-authored by [Claudius the Magnificent](https://github.com/lklimek/claudius) AI Agent</sub> --- src/backend_task/error.rs | 10 + .../wallet/derive_identity_key_for_display.rs | 8 +- .../wallet/sign_message_with_identity_key.rs | 7 +- src/context/identity_db.rs | 19 +- .../encrypted_key_storage.rs | 14 ++ src/wallet_backend/secret_access.rs | 44 +++- src/wallet_backend/single_key.rs | 201 ++++++++++-------- 7 files changed, 199 insertions(+), 104 deletions(-) diff --git a/src/backend_task/error.rs b/src/backend_task/error.rs index 99100ff4d..e5272f0dd 100644 --- a/src/backend_task/error.rs +++ b/src/backend_task/error.rs @@ -225,6 +225,16 @@ pub enum TaskError { )] IdentityKeyMissing, + /// An identity private key was found in the vault but its bytes are not a + /// usable signing key (vault corruption or a truncated write).

Alex opens a password-protected wallet as always and is prompted to unlock — - **the same unlock modal as today** (`wallet_unlock_popup.rs`). Nothing new - here; the migration needs this one passphrase entry and reuses the existing - flow. (This is the lazy-migration unlock from the plan's Migration section B.) -2. On successful unlock, migration runs inside the decrypt scope and flips - `uses_password=false`. -3. **Immediately after the wallet finishes unlocking**, a single global - info-style notice appears (see Copy A). It is the only new surface the user - sees. -4. On every subsequent open, that wallet **unlocks without a password prompt**. - This is expected because the notice in step 3 told Alex it would happen. - -### Why at the migrating unlock, and once per wallet - -- **At unlock, not app start:** the change is per-wallet and only becomes true at - the moment that specific wallet migrates. A startup banner would fire before - the fact is true, for wallets that may never be opened, and would be generic - noise. Tying the notice to the unlock makes it causally legible: "I just - unlocked, and *this* is what changed about *this* wallet." -- **Once per wallet, not once globally:** Alex may have one wallet with a - password and one without. The fact only applies to the protected one, and only - at its migration. A per-wallet one-time notice (keyed on the same `uses_password` - flip that drives the migration — fire when the flip happens, never again) is - the precise scope. After the flip, `uses_password` is already `false`, so the - notice naturally never re-fires for that wallet. -- **Not gating:** the password is *already* vestigial by the time we could ask - for acknowledgement — the wallet is unlocked and migrated. Gating would be a - speed bump in front of a decision the user cannot change and was made for them - by an approved plan.

This is **not** an alarm about a failure — tone in the copy stays calm and -forward-looking ("will return in a future update"). If the implementer finds -`Warning`'s long auto-dismiss still too short for a paragraph the user must read, -prefer a **manually-dismissed** (non-auto) banner over downgrading to `Info`. -The priority order is: *the user reads it once* > *it doesn't nag*. - -### Copy D — shared technical detail (details panel, optional click) - -> **Surface:** `with_details(...)` attached to Copy A and Copy B.

A user may opt in per identity to seal that identity's keys Tier-2 over the existing seam (Argon2id + XChaCha20-Poly1305) — no new crypto. The at-rest vault scheme is the single source of truth: scope_has_passphrase probes SecretSeam::scheme for the identity-key label (Protected -> prompt, Unprotected -> prompt-free, Absent -> IdentityKeyMissing), and decrypt_jit gains a symmetric Tier-2 arm. A protection-aware IdentityKeyView::store refuses a keyless write over a Protected label (IdentityKeyProtectionDowngrade), with store_unprotected as the deliberate opt-out downgrade. New crash-safe, idempotent migrations IdentityTask::Protect/UnprotectIdentityKeys re-seal an identity's keys keyless<->Tier-2 under one per-identity password. A display-only IdentityMeta sidecar carries the password hint + prompt copy (never the gate), seeded into the chokepoint's identity prompt index at identity load. UI: a collapsible 'Key Protection' section on the Key Info screen (default closed) with danger-gated opt-in (new password + confirm + strength + hint) and opt-out (verify) flows; PassphraseModalConfig gains remember_label so the sign-time prompt says 'key', not 'wallet'. Opted-in signing prompts just-in-time; headless yields SecretPromptUnavailable.

Two layers close it: (1) an identity-level fail-closed guard in encode_identity_blob_vault_first / migrate_keystore_to_vault refuses to move resident plaintext into the vault when the identity already has any Tier-2 key (IdentityKeyProtectionDowngrade / new KeystoreMigration::ProtectedSkipped), so a keyless write is impossible. (2) add_key_to_identity now seals the new key Tier-2 via SecretAccess::seal_new_identity_key, which prompts once, verifies the password against an existing protected key (so the identity stays under one password, with the standard wrong-pass re-ask), seals the new key, and marks it InVault before the save — headless yields SecretPromptUnavailable (fail closed; signing also fails closed earlier). KeyStorage::mark_in_vault performs the post-seal transition. SEC-002 (SHOULD-FIX): protect_identity_keys now re-enforces the password policy in the backend (validate_protection_password) so a non-UI caller cannot seal under a too-short password. SEC-003/SEC-004 tracked as code comments (store-guard TOCTOU bounded by the single-writer lock + UI in-flight gate; pre-opt-in plaintext may persist in freed filesystem blocks until reused). Tests: secret_access seal-new-key (seals Tier-2 under verified password / headless fails closed with no write / wrong-pass re-asks); identity_db encode+migrate refuse keyless on a protected identity; protect_identity_keys rejects a weak password. <sub>🤖 Co-authored by [Claudius the Magnificent](https://github.com/lklimek/claudius) AI Agent</sub> --- .../identity/add_key_to_identity.rs | 24 ++ .../identity/protect_identity_keys.rs | 37 +++ src/context/identity_db.rs | 193 +++++++++++++++ .../encrypted_key_storage.rs | 18 ++ src/wallet_backend/identity_key_store.rs | 6 + src/wallet_backend/secret_access.rs | 228 +++++++++++++++++- 6 files changed, 505 insertions(+), 1 deletion(-) diff --git a/src/backend_task/identity/add_key_to_identity.rs b/src/backend_task/identity/add_key_to_identity.rs index a2bde5b3f..27d0f3189 100644 --- a/src/backend_task/identity/add_key_to_identity.rs +++ b/src/backend_task/identity/add_key_to_identity.rs @@ -121,6 +121,30 @@ impl AppContext { let fee_result = FeeResult::new(estimated_fee, actual_fee); + // SEC-001: a password-protected identity must never acquire a keyless + // key.

charset=UTF-8 Content-Transfer-Encoding: 8bit Adding a key to a password-protected identity used to seal the new key Tier-2 (or fail closed) only during LOCAL persist, which runs AFTER the on-chain AddKeys broadcast. A headless add therefore broadcast the state transition on-chain and only then failed closed locally (no password) — leaving the key on-chain but never persisted by DET: an on-chain/local divergence. Move the protected-identity precondition BEFORE any on-chain side effect. `add_key_to_identity` now determines up front whether the identity is protected (`protected_identity_verify_scope`) and, if so, prompts for and VERIFIES its object password before building or broadcasting the state transition. Headless (`NullSecretPrompt` → `SecretPromptUnavailable`) or a wrong password returns the typed error before the broadcast, so no state transition is ever sent. The seal then runs after the broadcast with the already-verified password — a single prompt, split across the broadcast. `SecretAccess::seal_new_identity_key` is split into `verify_identity_object_password` (prompt + verify, returns an opaque `VerifiedIdentityPassword` that zeroizes on drop) and `seal_new_identity_key_with_password` (no prompt); the original composes the two and keeps its tests. The d965ca50 encode fail-closed guard (`IdentityKeyProtectionDowngrade`) stays as the defense-in-depth backstop. Also: O-1 — `mark_in_vault`'s bool return is now checked and warns on an unexpected miss (the encode guard still backstops it). O-3 — document that a Mixed identity fails closed on a plain re-save until "Finish protecting" reseals the remaining keys (intended secure behavior). <sub>🤖 Co-authored by [Claudius the Magnificent](https://github.com/lklimek/claudius) AI Agent</sub> --- .../identity/add_key_to_identity.rs | 219 +++++++++++++++++- src/context/identity_db.rs | 5 + src/wallet_backend/mod.rs | 3 +- src/wallet_backend/secret_access.rs | 212 +++++++++++++++-- 4 files changed, 406 insertions(+), 33 deletions(-) diff --git a/src/backend_task/identity/add_key_to_identity.rs b/src/backend_task/identity/add_key_to_identity.rs index 27d0f3189..8ad7811ba 100644 --- a/src/backend_task/identity/add_key_to_identity.rs +++ b/src/backend_task/identity/add_key_to_identity.rs @@ -6,6 +6,8 @@ use crate::model::fee_estimation::PlatformFeeEstimator; use crate::model::qualified_identity::PrivateKeyTarget::PrivateKeyOnMainIdentity; use crate::model::qualified_identity::QualifiedIdentity; use crate::model::qualified_identity::qualified_identity_public_key::QualifiedIdentityPublicKey; +use crate::wallet_backend::secret_prompt::SecretScope; +use crate::wallet_backend::{SecretAccess, VerifiedIdentityPassword}; use dash_sdk::Error as SdkError; use dash_sdk::Sdk; use dash_sdk::dpp::identity::accessors::{IdentityGettersV0, IdentitySettersV0}; @@ -27,6 +29,20 @@ impl AppContext { mut public_key_to_add: QualifiedIdentityPublicKey, private_key: [u8; 32], ) -> Result<BackendTaskSuccessResult, TaskError> { + // SEC-001 O-2: enforce the protected-identity precondition BEFORE any + // on-chain side effect.

A Mixed-state "Finish protecting" re-run with a different password is rejected up front with `IdentityKeyPassphraseIncorrect` and zero state changes, so an identity can never be split across two passwords. - `get_identity_by_id` now mirrors the bulk-load vault migration, so the single-get read path (and the SEC-001 protect/unprotect tasks that use it) migrates legacy resident `Clear`/`AlwaysClear` keys to the vault on read instead of returning and re-persisting plaintext. - A post-broadcast seal failure in `add_key_to_identity` now surfaces the typed, actionable `IdentityKeyAddedButNotSaved` (key is on-chain; retry after freeing disk space), preserving the upstream cause in the source chain — never a silent loss and never a keyless-write fallback. - The three prompt-meta setters recover a poisoned lock (`unwrap_or_else(|p| p.into_inner())`), matching `forget`/`forget_all`, so prompt-copy metadata can self-heal after a panicked reader instead of silently freezing. Adds regression tests for each (the blocker's split-prevention, read-path migration via an offline AppContext, and the typed orphan-error mapping). <sub>🤖 Co-authored by [Claudius the Magnificent](https://github.com/lklimek/claudius) AI Agent</sub> --- src/backend_task/error.rs | 15 +++ .../identity/add_key_to_identity.rs | 56 +++++++- .../identity/protect_identity_keys.rs | 74 +++++++++++ src/context/identity_db.rs | 124 ++++++++++++++++++ src/wallet_backend/secret_access.rs | 38 ++++-- 5 files changed, 294 insertions(+), 13 deletions(-) diff --git a/src/backend_task/error.rs b/src/backend_task/error.rs index d1051ebf2..5012ada0e 100644 --- a/src/backend_task/error.rs +++ b/src/backend_task/error.rs @@ -253,6 +253,21 @@ pub enum TaskError { )] IdentityKeyProtectionDowngrade, + /// A new key was accepted onto the identity ON-CHAIN, but sealing it into + /// the local secret vault afterward failed, so it is not yet saved on this + /// device.

The two mean very different things to a user: one is a permanent "this wallet does not exist", the other a momentary boot state. `resolve_wallet` cannot tell them apart on its own — a missing `id_map` entry covers both — and ~24 callers rely on its `WalletNotLoaded` for the genuine cold-boot case, so it must stay. Instead, resolve the existence question one layer up in `generate_receive_address`, where the DET-side wallet store (`self.wallets`) is the source of truth: unknown wallet -> `WalletNotFound`; known-but-not-yet-loaded -> `WalletNotLoaded`. This mirrors the sibling `generate_platform_receive_address`, which already does exactly this. Confirmed against design spec TC-019.

The fee was derived inline as `amount*1000 - (new_balance - balance_before)`, where `balance_before` came from the passed-in (post-reload, stale) `QualifiedIdentity`. When that cached balance lags the real platform balance, the apparent increase exceeds the minted credits and `saturating_sub` collapses the fee to zero — physically impossible, since a top-up can never grow the balance by more than the asset lock mints. Move the computation into `model/fee_estimation.rs` (DET policy: no inline fee math) as `resolve_identity_topup_actual_fee`, and have it fall back to the deterministic estimate whenever the balance delta yields a zero fee — the reliable signal that `balance_before` was stale. The happy path is unchanged (a consistent delta still reports the real processing fee). Adds unit tests for both the consistent-delta and stale-balance branches.

Coin selection draws from `spendable()` (confirmed + unconfirmed), and the "Max" button already reserves against `spendable()`, but several send paths still gated/validated on `confirmed`. The result: "Max" could exceed the validation, and sends coin selection would happily fund were rejected as "Insufficient confirmed balance" while funds showed as pending. Align the UI with the coin selector: - `send_screen::get_core_balance` -> `spendable()` (4 amount validations + the source-selector display). - wallets-screen send dialog validation -> `spendable()` (and drop the now-misleading "confirmed" from the message). - dashpay send_payment balance display + Max -> `spendable()`. No change to actually-correct sites: `snapshot_has_balance` already counts confirmed||unconfirmed, the MCP balances tool exposes all three buckets distinctly, and `.total` displays are intentional. Harness: `wait_for_spendable_balance` polled `.confirmed`, contradicting its own "spendable" contract, so it timed out whenever funding landed as IS-locked / unconfirmed. Poll `.spendable()` (the coin-selector set) and report it in the timeout diagnostic. Audit note: at the pinned platform-wallet rev (fb7953e / key-wallet 981e97f) IS-locked-FLAGGED UTXOs are classified `confirmed`, not `unconfirmed` — the balance has no separate IS-locked bucket. So `spendable()` (= confirmed + unconfirmed) is the correct, safe gate, not an over-count.

Add `register_wallet_with_retry`: bounded ~30s retry with backoff on the transient variants only (`WalletBackend`, `WalletBackendNotYetWired`, `WalletSeedStorage`, `WalletMetaStorage`); permanent errors surface immediately, and `WalletAlreadyImported` is returned as-is so the framework path keeps its idempotent-reuse branch.

Root cause is throughput saturation: the other fixes (and, before deferral, the dashpay tests) unmasked more funded-wallet registrations, and the suite runs serially (`--test-threads=1`), so as wallets accumulate in the upstream manager each later pickup round (bloom-filter rebuild + re-sync) exceeds the tight 30s budget. Give `create_funded_test_wallet`'s `wait_for_wallet_in_spv` the same 120s headroom the framework wallet already uses, via a named `FUNDED_WALLET_REGISTRATION_TIMEOUT`.

It relied on an external invariant (one password per identity) plus BTreeSet ordering rather than guarding itself. Add the SAME all-keys preflight the opt-in seal already runs (verify_existing_protection_password) at the top of unseal_identity_keys, before any store_unprotected write. Opt-out is now atomic by construction: a mismatch returns IdentityKeyPassphraseIncorrect up front with zero mutation, mirroring opt-in. The secret-seam ordering (vault write before sidecar delete) is untouched -- this only adds a read-only preflight. Resolves thepastaclaw's PR #867 finding. New test unseal_mixed_password_aborts_without_partial_downgrade seals two keys under different passwords and proves an opt-out that can open only the first key leaves both protected.

The shared message told both to close and reopen, which is a dead end for the legacy case.

Switch it to self.fee_estimator() (with_fee_multiplier(fee_multiplier_permille)) so the figure shown to the user tracks the live multiplier, matching the sibling top_up_identity path. Removed the now-dead local PlatformFeeEstimator import. Scoped to identity top-up estimates only (they feed the actual-fee band); transfer and other estimate sites remain in the deferred fee-multiplier cleanup.
