Subject: [PATCH 01/23] ci: place every job through the shared router

These workflows addressed RunsOn EC2 Spot directly, so they bypassed the
capacity router entirely and pinned this repository to a cloud provider that
is being retired.

Each job now calls the shared router in .github-private, which prefers idle
permanent self-hosted capacity and spills to cloud overflow only when the
local fleet is busy. Runner classes were derived from the vCPU band each job
already asked for, then raised where the job body shows it needs Docker or a
browser, and deployment jobs that hold production credentials were pinned to
the local fleet so a reclaimed cloud instance cannot interrupt a cutover.

No step logic changed.

Subject: [PATCH 02/23] ci: route through the vendored local adapter

GitHub does not expose private reusable workflows to public callers, so
the cross-repo reference to .github-private failed at startup. The
vendored adapter fetches the pinned router files at runtime.

Subject: [PATCH 03/23] Read each protocol's authority feed on its page

The protocol detail page described every authority as a list of facts
and showed live pulse sightings only for verified protocols; the
authority's own activity feed had no route into the page. Add one: the
page now reads /universe/protocols/:id/activity and renders the feed
with the authority's records intact, the checkpoint it was proven
through, and an explicit line for every unserved state, so an outage
never reads as an empty protocol. A pure reader finds the identity,
kind, transaction and height keys the feeds share without flattening
each protocol's own field names.

Subject: [PATCH 04/23] Open the ANIMA evidence explorer

ANIMA's protocol state machine had no explorer surface. Add the ANIMA
Evidence Explorer: a lazy module at /anima serving the logged transition
list (/anima/transitions, with /anima/events as the same component so
the two names cannot drift), one transition by its composite id, the
organism list, one organism with its waymarks and achievements, and one
organism's history beside its lineage. Every page reads only
index-anima through the /api/v1/anima overlay and states unconfigured,
unavailable, and proven-miss states as what they are. The landing page
is the common registry shell at /protocols/anima, which the registry
entry turns on once the deployed release verifies against the
authority.

+# ANIMA Evidence Explorer
+
+The ANIMA product shows the ANIMA protocol state machine as its first-party
+authority sees it. index-anima follows the Bitcoin chain, applies blocks to
+the protocol state with undo records, and serves organisms, lineage, and the
+logged transition list. The explorer reads only from that authority. It never
+infers state, ownership, or balances from transaction shape.
+
+## What it does
+
+- `/protocols/anima` - the protocol landing page in the common registry shell:
+  identity, authority, readiness, and the same availability model every
+  protocol uses.
+- `/anima/transitions` and `/anima/events` - the logged transition list,
+  oldest first, cursor-free positional paging. One component serves both
+  paths so the two names cannot drift.
+- `/anima/event/:eventId` - one logged transition with its Bitcoin anchor and
+  the organisms it touched. Event ids look like `aHEIGHT:txIndex` and are
+  issued by the explorer.
+- `/anima/items` - the organism list with created height, status, and origin.
+- `/anima/item/:itemId` - one organism: identity, current vessel, genome,
+  waymarks, and achievements.
+- `/anima/item/:itemId/history` - the organism's transition history beside
+  the lineage document (parents, children, ancestors, descendants).
+
+On every protocol detail page, a "Recent activity from its authority" panel
+serves the protocol's own feed when the authority publishes one.
+
+## Data source authority
+
+| Fact | Source |
+| --- | --- |
+| Protocol parameters, tip, supply | index-anima `/anima/status` |
+| Logged transitions | index-anima `/anima/events` |
+| Organism records and lineage | index-anima `/anima/organism`, `/anima/lineage` |
+
+index-anima is an open authority: it serves public, chain-derived data with
+no authentication, and the explorer sends no credential to it.
+
+## Verification semantics
+
+The single-transition lookup is served honestly over a positional surface:
+the event id encodes its block height, so the backend binary-searches the
+authority's list and reports a proven miss rather than paging blindly. A
+404 from `/anima/event/:id` means the authority logs no such event.
+
+## Failure states
+
+- An unconfigured authority is a served document with an explicit
+  `unconfigured` state and a plain-language reason. It is never rendered as
+  an empty protocol.
+- An authority that cannot answer is a 502 on the API and a stated degraded
+  panel on the page. It is never rendered as zero activity.
+- An organism or transition that provably does not exist is a 404.
+
+## Privacy boundary
+
+index-anima sees hashes, never contents. The explorer adds no collection of
+user data: these pages are accountless, and nothing typed into them is sent
+anywhere beyond the read requests described above.
+
+## Self-hosting
+
+Deploy index-anima against a Bitcoin Core node with transaction indexing,
+then add it to the explorer backend's source registry:
+
+```
+[{"authorityId":"index-anima","origin":"http://127.0.0.1:8788",
+  "protocols":["anima"],"network":"bitcoin:mainnet"}]
+```
+
+No bearer token is needed. The value above matches the authority's default
+port; change it to match the deployment.
+
+## Release status
+
+The registry entry ships BLOCKED. It is upgraded to verified only after the
+authority answers in a deployed release and the explorer reads live data
+through it, following the same evidence bar as every other protocol in the
+registry.

Subject: [PATCH 05/23] Let the ANIMA pages and the activity panel compile
 under template checks

The Angular template type checker cannot narrow a discriminated union
through ngSwitch, so the ready-state fields were unreachable to the
templates even though tsc alone accepted them. The ANIMA view models
and the protocol activity state become single interfaces with optional
fields, which is the shape the rest of the universe pages already use,
and the transitions page no longer nests one translatable section
inside another.

Subject: [PATCH 06/23] Put the ANIMA routes and the activity feed inside the
 gates

The visual matrix walks one route list, and the ANIMA pages were not in
it: three new routes would have shipped with no screenshot, contrast
probe, or unfinished-page check. They join the list beside fixtures for
the served ANIMA documents and a registry entry in the contract's own
shape, so /protocols/anima renders the real page under the gates.

The activity panel also refuses an envelope that is not the documented
document: a gateway page or an older release resolves to the explicit
unsupported page instead of flowing into the template as feed data,
which is what an unmatched fixture or a mismatched deploy would have
served it.

Subject: [PATCH 07/23] List each protocol's objects beside its activity

The protocol page read the authority's feed but not its standing
collection, so the seven protocols whose authorities page objects
rather than events still had no surface. Add an objects panel on the
same terms: records kept whole, a load-more cursor, the checkpoint
beside them, and an explicit line for every unserved state. A pure
reader finds the identity and status keys the collections share.

Subject: [PATCH 08/23] Build Portfolio Intelligence 2.0: routes, vault,
 aggregation, and seven products

Transform the address-centric portfolio into the Portfolio Intelligence
product on the shared v2 contract artifact (vendored, source-hashed,
generated by backend-apis).

- Routes: /portfolio home, new, manage, settings, workspace migration,
  p/:id/overview|holdings|activity|performance|time-machine|utxos|insights|
  sources|reports, share/:shareId, and the legacy address route rendered
  in ephemeral mode. Static routes are declared before the legacy dynamic
  route.
- Encrypted local vault: IndexedDB envelopes (AES-256-GCM via WebCrypto),
  Argon2id KDF in a Web Worker (hash-wasm) with calibrated PBKDF2
  fallback, constant-shape unlock failures, change passphrase, validated
  encrypted backup export/import, complete local deletion, auto-lock.
- Watch-only onboarding: xpub/ypub/zpub and descriptor accounts via
  @scure/bip32, utxo-descriptors checksums, @scure/btc-signer address
  encoding in a discovery worker; private keys, WIF, and mnemonics are
  rejected locally before any network request and never echoed.
- Local aggregation engine: address dedupe with an explicit inclusion
  policy, exact BigInt merges, pessimistic source-state folding,
  internal transfers as movement (never flows), explicit unknown
  buckets, deterministic output.
- Products: overview (hero, allocation, drivers), holdings with
  expansion and mobile cards, collectibles gallery, semantic activity,
  Time Machine comparisons, UTXO center with safety classes and
  effective-value economics, FIFO performance, deterministic insight
  engine, redacted report builder, client-encrypted share view,
  watchlist migration, alert rules extension.
- 65 new vitest suites for the pure engine layer (BIP84 vector pinned);
  full suite 554 green; production build passes the text and palette
  gates.

Subject: [PATCH 09/23] Name the type the objects reader renders, and page on
 the cursor it has

The objects summary named the objects page type without importing it,
and the load-more button asked an objects page whether it has more
rows, which is an activity-page field; an objects page only promises a
next cursor. The production build compiles again.

+# Portfolio Intelligence 2.0
+
+A private, multi-portfolio intelligence product for Bitcoin-native assets
+and UTXOs, built on the exact-value and evidence model of the address
+portfolio. Read-only: no wallet, no signing, no broadcasting, no custody.
+
+The companion API contract lives in `bitcoinuniverseio/backend-apis`
+(`src/universe-portfolio/v2/`), and its generated, source-hashed frontend
+artifact is vendored at `frontend/src/app/shared/universe-portfolio-v2.types.ts`.
+
+## Routes
+
+| Route | Purpose |
+| --- | --- |
+| `/portfolio` | Product home. Onboarding when empty; locked shell when locked; last active portfolio when unlocked. |
+| `/portfolio/new` | Onboarding wizard: one address, watch-only wallet, address list, or manual-only. |
+| `/portfolio/manage` | Create, rename, duplicate settings, archive, restore, delete, switch. |
+| `/portfolio/settings` | Vault passphrase, encrypted backup, import, complete local deletion. |

+
+## The vault
+
+All private portfolio data (names, accounts, xpubs, descriptors, derived
+inventories, labels, annotations, views, alert rules, snapshots, manual
+positions, UTXO protection flags, share tokens) lives in a versioned
+IndexedDB vault. Every record is an individually authenticated ciphertext
+(AES-256-GCM via WebCrypto). The master key is derived from the
+passphrase with Argon2id (hash-wasm) inside a Web Worker - with a
+calibrated PBKDF2 fallback where Argon2id cannot run - imported as a
+NON-EXTRACTABLE key, and never persisted. Locking, closing the browser,
+or an inactivity timeout destroys it.
+
+Backup export produces a `.universe-portfolio` file: format version, KDF
+metadata, record counts, payload checksum, application release, and
+migration range. Import validates the whole archive and the passphrase
+before touching any local state. Browser encryption protects against
+network and server compromise; it cannot protect against a fully
+compromised device, and the product says so.
+
+## Watch-only accounts
+
+Extended public keys (xpub/ypub/zpub and testnet variants) and public
+output descriptors are supported through audited libraries: @scure/bip32
+for derivation, utxo-descriptors for BIP-380 parsing and checksums,
+@scure/btc-signer for address encoding. Derivation runs in a worker.
+Discovery scans receive and change branches with an adjustable gap limit
+(default 20), is resumable and cancellable, and never reports complete if
+a required address read failed.
+
+Seed phrases, extended private keys, WIF keys, raw private-key hex, and
+seed-export files are detected locally before any network request,
+rejected with a safety explanation, and never echoed or retained. The
+extended public key or descriptor itself never leaves the browser: only
+derived public addresses are sent to the first-party portfolio API.
+
+## Truthfulness rules
+
+- Every quantity, price, and total is an exact decimal string. Floating
+  point never touches a balance.
+- The seven source states (proven, partial, outside_coverage, pending,
+  stale, unavailable, unsupported) are never collapsed to zero.
+- Historical reconstruction never silently falls back to current
+  holdings; gaps stay gaps, and protocol history is named as outside
+  coverage rather than inferred.
+- Internal transfers between included accounts are movement, not
+  economic inflow or outflow; fees stay costs.
+- Duplicate addresses are counted once; an explicit inclusion policy
+  resolves which account owns them.
+- Unpriced holdings keep their exact quantities and are excluded from
+  the priced subtotal, visibly.
+
+## Privacy mode
+
+One global control with three levels: open, values hidden, presentation
+(percentages only). Hidden values are absent from the DOM and the
+accessibility tree: components bind masked placeholders rather than
+blurring rendered numbers. Charts, exports, and reports respect the
+mode.
+
+## Local protection flags
+
+A UTXO protection flag is a local note in the encrypted vault. It is
+never presented as a wallet lock or an on-chain condition, and it exists
+to warn, label, and organize. The consolidation analysis is informational
+only: it never builds, signs, or broadcasts anything.
+
+## Shares
+
+A share encrypts a redacted snapshot in the browser with a random key,
+uploads only ciphertext plus expiry metadata, and puts the key in the URL
+fragment, which the server never receives. Recipients decrypt locally.
+Shares expire, are revocable with the locally stored deletion token, and
+the server logs neither keys nor plaintext.

Subject: [PATCH 11/23] Reconcile with develop: supersede the workspace
 product, reuse its importers

- The old /portfolio/workspace UI is superseded by the Portfolio
  Intelligence products; the compatibility route now serves the
  vault migration and redirect as locked by the spec.
- The workspace CSV/JSON importers are preserved and reused by the
  onboarding address-list flow, so labels and groups carry over.
- Force-add the portfolio data services (the repo's legacy 'data'
  ignore pattern shadowed them).
- Include the Portfolio Intelligence product documentation.

+# Portfolio Intelligence 2.0
+
+A private, multi-portfolio intelligence product for Bitcoin-native assets
+and UTXOs, built on the exact-value and evidence model of the address
+portfolio. Read-only: no wallet, no signing, no broadcasting, no custody.
+
+The companion API contract lives in `bitcoinuniverseio/backend-apis`
+(`src/universe-portfolio/v2/`), and its generated, source-hashed frontend
+artifact is vendored at `frontend/src/app/shared/universe-portfolio-v2.types.ts`.
+
+## Routes
+
+| Route | Purpose |
+| --- | --- |
+| `/portfolio` | Product home. Onboarding when empty; locked shell when locked; last active portfolio when unlocked. |
+| `/portfolio/new` | Onboarding wizard: one address, watch-only wallet, address list, or manual-only. |
+| `/portfolio/manage` | Create, rename, duplicate settings, archive, restore, delete, switch. |
+| `/portfolio/settings` | Vault passphrase, encrypted backup, import, complete local deletion. |
+| `/portfolio/workspace` | Compatibility route: migrates the old plaintext watchlist into the vault, then redirects. |
+| `/portfolio/p/:id/overview` | Value hero, coverage, allocation, change drivers. |
+| `/portfolio/p/:id/holdings` | Unified holdings: table, grouping, expansion, per-location custody, collectibles gallery. |
+| `/portfolio/p/:id/activity` | Portfolio-wide semantic timeline, internal transfers included as movement. |
+| `/portfolio/p/:id/performance` | FIFO P&L per included account, proven history only. |
+| `/portfolio/p/:id/time-machine` | Compare two historical points; exact delta decomposition. |
+| `/portfolio/p/:id/utxos` | UTXO inventory, safety classification, effective value, consolidation analysis. |
+| `/portfolio/p/:id/insights` | Deterministic, versioned insight rules. |
+| `/portfolio/p/:id/sources` | Coverage disclosure: what every authority answered, with checkpoints. |
+| `/portfolio/p/:id/reports` | Redacted report builder with exact preview. |
+| `/portfolio/share/:shareId` | Client-encrypted expiring snapshot shares. |
+| `/portfolio/:chain/:network/:address` | Legacy public route, rendered in ephemeral mode. Nothing is stored. |
+
+## The vault
+
+All private portfolio data (names, accounts, xpubs, descriptors, derived
+inventories, labels, annotations, views, alert rules, snapshots, manual
+positions, UTXO protection flags, share tokens) lives in a versioned
+IndexedDB vault. Every record is an individually authenticated ciphertext
+(AES-256-GCM via WebCrypto). The master key is derived from the
+passphrase with Argon2id (hash-wasm) inside a Web Worker - with a
+calibrated PBKDF2 fallback where Argon2id cannot run - imported as a
+NON-EXTRACTABLE key, and never persisted. Locking, closing the browser,
+or an inactivity timeout destroys it.
+
+Backup export produces a `.universe-portfolio` file: format version, KDF
+metadata, record counts, payload checksum, application release, and
+migration range. Import validates the whole archive and the passphrase
+before touching any local state. Browser encryption protects against
+network and server compromise; it cannot protect against a fully
+compromised device, and the product says so.
+
+## Watch-only accounts
+
+Extended public keys (xpub/ypub/zpub and testnet variants) and public
+output descriptors are supported through audited libraries: @scure/bip32
+for derivation, utxo-descriptors for BIP-380 parsing and checksums,
+@scure/btc-signer for address encoding. Derivation runs in a worker.
+Discovery scans receive and change branches with an adjustable gap limit
+(default 20), is resumable and cancellable, and never reports complete if
+a required address read failed.
+
+Seed phrases, extended private keys, WIF keys, raw private-key hex, and
+seed-export files are detected locally before any network request,
+rejected with a safety explanation, and never echoed or retained. The
+extended public key or descriptor itself never leaves the browser: only
+derived public addresses are sent to the first-party portfolio API.
+
+## Truthfulness rules
+
+- Every quantity, price, and total is an exact decimal string. Floating
+  point never touches a balance.
+- The seven source states (proven, partial, outside_coverage, pending,
+  stale, unavailable, unsupported) are never collapsed to zero.
+- Historical reconstruction never silently falls back to current

+(percentages only). Hidden values are absent from the DOM and the
+accessibility tree: components bind masked placeholders rather than
+blurring rendered numbers. Charts, exports, and reports respect the

Subject: [PATCH 13/23] Route /api/v2/universe/* to the protocol overlay

Portfolio API v2 registers its own versioned prefix on the overlay; the
gateway names it explicitly so the v2 family is served from the same
read-only process as v1 and never falls through to the Bitcoin backend.

Subject: [PATCH 14/23] Draw the overview chart from the shared chart theme

The brand pink was a raw literal; the chart now reads the semantic
series, axis, grid, and label colours from chartChrome(), so it follows
the theme tokens like every other Universe chart.

call sites in total. Every catch now routes through the real signature
with a 500 and the error's message.

develop's frontend did not compile either: seven vertical components
formatted raw strings through the Number global in templates, which AOT
strict templates refuse, so each component now binds it; and the ark
dashboard imported an ArkVirtualTx type that was never added to
universe.types - it is now mirrored from backend ark.types.

Subject: [PATCH 19/23] Name the vertical test files by the backend convention

The production build compiles with tsconfig.build.json, which excludes
*.test.*; the net-new verticals shipped *.spec.ts files, so jest types
were missing and the backend release build failed. The backend's 22
existing suites are all *.test.ts - the eleven new ones now match.

Subject: [PATCH 20/23] Annotate the vertical services for the await-safety
 rule

The vertical route handlers await service methods; the repo's
no-unhandled-await rule requires those callees to carry the @asyncSafe
tag the rest of the backend's services carry. The one test that awaits
a rejection now uses the rule's explicitly-handled two-argument then
form.

Subject: [PATCH 21/23] Keep the desktop nav on the page and the anima crumbs
 on the touch floor

Four new destinations outgrew the desktop nav row: at 1024px the row
overflowed into page-level sideways scrolling on every route the mobile
gate measures. The desktop row now wraps, so every destination stays
visible without a second scroll affordance.

The anima breadcrumbs are repeated controls and measured 43.56px wide, a
hair under the 44px touch floor; they now carry the token like every
other repeated target.

Both verified locally: scripts/universe/visual-qa/mobile-check.mjs over
the built bundle reports no mobile failures.
