 ### Fixed
 
+- **Speculative phantoms were injected unmarked, made immortal by one retrieval, and identified by `os.urandom` ([#1171](https://github.com/robotrocketscience/aelfrice/issues/1171)).** Four defects on the wonder phantom lifecycle, all confirmed by execution. *Injection:* nothing in the hook formatter distinguished a phantom from a belief a user actually asserted — `retrieval.py` contains no reference to `speculative` and `search_beliefs` filters only on `valid_to`, so a machine-synthesised conjecture reached the model's context byte-identically to ground truth. The rendered `<belief>` line now carries `speculative="1"`, with a framing sentence added only to blocks that contain one, in all four envelopes that reach an agent (`UserPromptSubmit`, its session-start variant, the `SessionStart` baseline, and the `PreToolUse` worker-context block a subagent receives); the attribute is a fixed literal selected by an equality test, never interpolated from belief data, so content cannot forge it. It keys on `origin`, so a phantom the user has validated correctly loses the marker. *Immortality:* `wonder_gc` excluded any phantom carrying a `feedback_history` row, as a proxy for "the posterior was touched" — but #1086 made every retrieval write an audit-only row *without* moving the posterior, so a single keyword-overlapping prompt made a phantom permanently uncollectable at its ingest prior and the 14-day TTL never fired again. Measured: `query_wonder_gc_candidates` went from returning the phantom to returning nothing after one `record_retrieval`, α and β unchanged at 0.3/1.0. Exposure-only sources are now exempt from that clause, which is safe because the α/β band is the exact guard — `_bayesian_update` only ever increases α or β and zero valence is rejected at the boundary, so real endorsement (including `AELFRICE_EXPOSURE_UPDATES_POSTERIOR=1`, verified) still protects the belief. *Identity:* phantoms were the only beliefs in the store keyed by `ulid()` (`time.time()` + `os.urandom(10)`), so two wonder runs over an identical store minted different ids and therefore a differently-shaped `RELATES_TO` subgraph — an operator could not answer "how did this store get from belief A to phantom P" from identity. The id is now derived from the same constituent-set + generator hash that already drives dedup, so the same derivation resolves to the same id in any store; pre-existing phantoms keep their ULIDs and dedup on `content_hash` prevents collision. *Zero-signal promotion:* `_jaccard` returns 1.0 for the empty/empty pair, so an `aelf lock` text that normalized to no tokens (all stopwords) scored a perfect match against any phantom that also stripped to nothing, silently promoting it to `user_validated`. Pass 2 is skipped when the lock text carries no signal. Also strikes the `BELIEF_SPECULATIVE` docstring's claim that "C4 retags this → real type on threshold" — no such retag exists on any path and `promote()` documents that it leaves `type` alone; `type` is a permanent provenance marker and `origin` is the trust tier. Surface B auto-promotion on a genuine ≥0.9 match is ratified design and unchanged. **Not covered:** phantom creation still writes no `ingest_log` row, so the write trail is incomplete even though the derivation is auditable through its `RELATES_TO` edges and `wonder_ingest` corroboration row; routing it through the log needs a new `derive()` branch and therefore touches the replay-equality contract, tracked separately.
 - **`aelf uninstall --purge` and `--archive` left the belief corpus on disk, and `--archive` could encrypt an empty database ([#1173](https://github.com/robotrocketscience/aelfrice/issues/1173)).** Disposition deleted exactly one file, `memory.db`. Everything else the package writes beside the store survived: the SQLite `-wal`/`-shm` sidecars, backup DBs left by past migrations, the BM25F index, the per-turn hook injection log (which stores the rendered block verbatim, i.e. belief content), the belief-write feed log, per-session hook state, and the `transcripts/`, `rebuild_logs/`, and `telemetry/` directories. On a store held open by a running hook — the normal deployment shape — the un-checkpointed WAL is where the content actually lives, so a `--purge` deleted a near-empty shell and left the corpus in plaintext beside it. The same omission made `--archive` a **data-loss** bug rather than only a privacy one: it encrypted `db_path.read_bytes()` without checkpointing first, so the archive captured a valid-but-stale database. Measured against a live 30-belief store: 0 beliefs recoverable from the archive, `memory.db` deleted, all 30 sitting in plaintext in the surviving `memory.db-wal`; the user was told "original deleted". Both modes now checkpoint the WAL and operate on the enumerated artifact set, and the same run recovers 30/30. Each mode prints a manifest — every path with its size — before destroying anything; `--archive` additionally discloses, before it takes a password, that the derived artifacts are deleted rather than encrypted (an encrypted archive beside plaintext copies is not a guarantee). The archive destination is excluded from its own removal set. Artifacts whose names are generic (`transcripts/`, `hook_audit.jsonl`, …) are removed only when the store sits in a directory the package created; `$AELFRICE_DB` is honoured verbatim, so a store at `~/memory.db` must not cost the user `$HOME/transcripts/` — those are listed for manual removal instead of deleted. Uninstall now also passes `--rebuilder` to the delegated unsetup (the PreCompact entry was left pointing at a binary the closing message tells the user to `pip uninstall`, so every later compaction spawned a missing command) and clears the manifest-version and uv-migration stamps, so reinstalling the same version re-merges the hooks instead of short-circuiting into an installed-but-inert state. `opt-out-hooks.json` is deliberately preserved. **Not covered:** the rest of `~/.aelfrice/` is still left in place, including the LLM consent sentinel — `projects/` there holds *other projects'* stores, so a blanket home-directory sweep would destroy corpora the command was not asked to touch. `docs/user/INSTALL.md` documents the residue and the manual step; a scoped follow-up is tracked separately.
 - **`aelf doctor --classify-orphans` sent stored belief content with no consent prompt ([#1172](https://github.com/robotrocketscience/aelfrice/issues/1172)).** The documented boundary is four gates, the fourth being a recorded consent sentinel. `check_gates` covers only the first three and leaves gate 4 to the caller; `aelf onboard` wired it, `--classify-orphans` did not — it hardcoded `enabled=True`, never read the sentinel, and transmitted the content of every orphan belief to the vendor API. With the `[onboard-llm]` extra installed and `ANTHROPIC_API_KEY` exported (both common), a *diagnostic* subcommand shipped the memory store outbound with no prompt, and because no sentinel was ever written, `aelf doctor revoke-llm-consent` could not prevent it. Consent is now **scoped**: a sentinel records which data classes the accepted prompt disclosed. `aelf onboard` grants `onboard_candidates`; `--classify-orphans` requires `stored_beliefs` and prompts separately with a disclosure naming stored belief content — the onboard text never did, since it enumerates document sentences, commit subjects and docstrings and promises "nothing outside the extracted candidate text". Pre-existing sentinels have no `scopes` key and are read as onboard-only, so they do not grandfather this path. Granting either scope preserves the other. `--dry-run` still previews the candidate set with no gate check and no network call.
 - **Codex `$aelf-onboard` classifies on a low-tier model, not the session model ([#1153](https://github.com/robotrocketscience/aelfrice/issues/1153)).** onboard's bulk sentence-classification fan-out defaults to a low-cost model tier (tier-abstract since [#1155](https://github.com/robotrocketscience/aelfrice/issues/1155)). The Codex skill generator carried the slash body verbatim with only a generic "use Codex's own subagent mechanism" note, so on Codex a bare "low-cost tier" default had nothing concrete to resolve to and the work fell through to the session's default model (e.g. `gpt-5.6-luna`): the expensive, slow path for short-label classification. `codex_skill_from_slash` now appends, for the onboard skill, an adapter note resolving that default to Codex's cheapest fast tier (a `-mini`-class model) rather than the session default, without pinning a model id (names drift). Deterministic transform; the note is onboard-specific, so subagent skills with no model directive (reason/wonder) don't carry it. Surfaced during the #1056 live validation.
