fix(wake): #964 re-verdict — record-only polarity, both-forms deny, absent-ledger refusal

Answers the NOT CLEAR verdict on #964 (B2 cases C+D, B11), new commit per
the re-verdict terms.

- B2-D (polarity): extras are RECORD-ONLY by default; byte capture for an
  extra requires WAKE_PREIMAGE_CAPTURE opt-in. Core set (adapter,
  watch-list) stays capture-eligible. Case D is safe by polarity alone —
  verified with the content shape list stubbed to always-allow.
- B2-C (both forms): path deny evaluates raw AND realpath-resolved
  candidate forms against unresolved AND resolved mosaic-home anchors;
  deny runs first in the gate chain, so an allowlisted symlink cannot
  smuggle a denied target.
- Content deny is defense-in-depth on the opt-in path only: six scrub
  shapes + named-assignment probe; probe errors fail TOWARD refusal
  (grep rc>=2 is a deny, not a fall-through).
- B11: absent/empty ledger over non-empty objects/ is a loud non-zero
  refusal to re-baseline — that state cannot be a first install.
- Suite: P2 moved to the core adapter; P4/P5/P10 exercise the opt-in
  path; new needles P13-P17 mirror every verdict probe (symlinked store,
  outside-store copy, live secret no-opt-in/opt-in, record-only
  tracking, ledger deletion, allowlist-symlink both halves). Red-first:
  pre-fix code fails exactly P13/P14/P15/P16 (14 assertions); fixed
  17/17. P17's deny half is green pre-fix (basename rule) — kept as a
  guard needle, disclosed in the PR body.

All 10 wake suites green.

+# preimage.sh — A11 of the wake canon (#958): durable PROVENANCE for the
+# OPERATOR-SIDE preimage definition.
+#
+# THE GAP THIS CLOSES (#958): every observed_hash in the lane store is
+# sha256(adapter stdout) — the operator's source adapter (plus the watch-list
+# and any operator-declared preimage files) IS the preimage definition for
+# every hash the pipeline ever records. Those files live OUTSIDE the versioned
+# wake component, so a byte change to them was attributable only through agent
+# transcripts: provenance thinner than any hash it feeds. A changed preimage
+# also re-baselines EVERY source at once, which previously surfaced only as N
+# per-source deltas / UNACCOUNTED lines with no first-class cause.
+#
+# WHAT THIS TOOL DOES:
+#   - Derives the PREIMAGE SET generically (no operator paths baked in):
+#       * the resolved file behind WAKE_DETECTOR_SOURCE_CMD (first word),
+#       * the WAKE_WATCH_LIST file,
+#       * operator-declared extras via WAKE_PREIMAGE_EXTRA (colon-separated —
+#         e.g. sink/feed scripts). Extras are RECORD-ONLY by default (see the
+#         credential hard gate below); never list key-material files.
+#   - Records each file's (sha256, size, mtime, ts) as an APPEND-ONLY ledger
+#     row in <state>/preimage/preimage-ledger.jsonl and stores the full bytes
+#     CONTENT-ADDRESSED at <state>/preimage/objects/<sha256> — so a change is
+#     attributable (prior bytes + change time) from durable state alone, with
+#     no transcript required. Acceptance (a) of #958.
+#   - On a CHANGE (not first-seen), `check --enqueue` enqueues ONE first-class
+#     class=actionable entry per changed file via the store's single allocator
+#     (#908), carrying a §2.1 hard locator (`path`), BEFORE the per-source
+#     deltas it explains are observed — so the digest shows the cause line,
+#     not just N re-baselined sources. Acceptance (c).
+#
+# CREDENTIAL HARD GATE — acceptance (b): the mechanism must be UNABLE to
+# capture credential material even by operator error. Layered, every layer
+# fail-closed toward NOT capturing bytes (the hash/size/mtime row is still
+# written — change-time attribution survives, content capture does not;
+# a sha256 discloses nothing about the bytes):
+#   1. POLARITY (#964 review, case D): byte capture is DENY-BY-DEFAULT for
+#      operator extras. WAKE_PREIMAGE_EXTRA paths are RECORD-ONLY (rows +
+#      first-class change entries, no bytes) unless explicitly listed in
+#      WAKE_PREIMAGE_CAPTURE — a shape list can only refuse the secrets
+#      someone already enumerated, so arbitrary operator-pointed files must
+#      not default to capture. The CORE set (the resolved adapter file, the
+#      watch-list) is capture-eligible: it IS the preimage definition this
+#      tool exists to snapshot, and the deny layers below still apply to it.
+#   2. PATH deny: the mosaic credential store locations
+#      (<mosaic-home>/credentials.json, <mosaic-home>/tools/_lib/
+#      credentials.json, anything under <mosaic-home>/credentials/, and any
+#      file literally named credentials.json) are refused. Evaluated on BOTH
+#      the operator-supplied form AND the symlink-resolved form, against BOTH
+#      the unresolved and resolved forms of the mosaic-home anchor — a deny
+#      list written only in unresolved paths cannot match a path that was
+#      resolved before it arrived (#964 review, case C).
+#   3. CONTENT deny: a candidate whose bytes match the well-known secret-token
+#      shapes (same conservative set digest.sh redacts: PAT/Slack/AKIA/JWT/PEM)
+#      OR a named-assignment secret shape (key/token/secret/passw/hmac/
+#      credential/bearer = long unbroken value — catches prefix-less
+#      high-entropy keys, e.g. an HMAC key in an env file) is refused —
+#      refusal, not redaction: a redacted preimage would be a false witness,
+#      and secret bytes must never land in the object store. Deliberately
+#      conservative toward REFUSAL: a false match only withholds byte capture,
+#      never tracking.
+#   Plus a size cap (WAKE_PREIMAGE_MAX_BYTES, default 1 MiB) so a stray extra
+#   pointing at a large binary cannot turn provenance into data hoovering.
+#   Deny ALWAYS wins over the WAKE_PREIMAGE_CAPTURE opt-in.
+#
+# FAIL-LOUD DISCIPLINE (the D2/#955 class, both layers): an infrastructure
+# failure of THIS tool (unresolvable adapter, unreadable/corrupt ledger,
+# failed durable write, failed enqueue) exits NON-ZERO and is never read as
+# "no change". A corrupt ledger REFUSES to compare (and to re-baseline):
+# silently restarting history would erase the very attribution this exists
+# to provide. Likewise (#964 review, B11) an ABSENT/EMPTY ledger while
+# objects/ still holds prior captures is DELETED HISTORY, not a first
+# install — it refuses loudly instead of re-baselining, because a silent
+# restart would absorb the next real change as first-seen.

+# test-wake-preimage.sh — RED-FIRST invariant harness for A11 (#958): durable
+# provenance for the OPERATOR-SIDE preimage definition (preimage.sh).
+#
+# Each test asserts ONE #958 invariant and is designed to go RED if it
+# regresses:
+#   P1  first-seen -> SILENT baseline (ledger rows, NO enqueue)   (detector idiom)
+#   P2  change -> attributable from durable state alone: new ledger row with
+#       prev, PRIOR BYTES retrievable content-addressed, first-class actionable
+#       enqueued with a §2.1 hard locator (path)                 (acceptance a+c)
+#   P3  detector ordering: the preimage cause line is enqueued at a LOWER
+#       observed_seq than the per-source delta it explains        (acceptance c)
+#   P4  credential-store PATH is refused — bytes NEVER captured, even when the
+#       operator lists it by error (hash/mtime row still written) (acceptance b)
+#   P5  secret-SHAPED content is refused — refusal, not redaction (acceptance b)
+#   P6  deletion of a preimage file is a tracked CHANGE (ABSENT), not an error
+#   P7  no-change is idempotent (no row growth, no enqueue)
+#   P8  unresolvable adapter command -> FAIL LOUD, never "no change" (D2/#955 class)
+#   P9  corrupt ledger -> REFUSE to compare/re-baseline (loud, no append)
+#   P10 oversized file -> bytes refused, hash still recorded (no data hoovering)
+#   P11 reconcile pre-step: a preimage change surfaces as a first-class line
+#       BEFORE the UNACCOUNTED enumerations it explains           (acceptance c)
+#   P12 detector: preimage infra failure is LOUD (pass exits non-zero) but does
+#       NOT starve source observation
+#
+# Regression needles from the #964 NOT-CLEAR review (decoy method: plant the
+# bytes, grep the WHOLE state dir — the decoy does not know what the code
+# believes):
+#   P13 case C: symlinked/renamed credential store (mosaic-home itself behind
+#       a symlink; a renamed target outside every path rule) — refused on BOTH
+#       path forms / by content, bytes grep-absent          (acceptance b)
+#   P14 case D: prefix-less high-entropy key (detector.env class) — safe
+#       WITHOUT opt-in by POLARITY alone (must hold with the shape list
+#       deleted), and refused WITH opt-in by the named-assignment shape
+#   P15 polarity: extras are RECORD-ONLY by default (change row + enqueue, no
+#       bytes); byte capture requires explicit WAKE_PREIMAGE_CAPTURE opt-in
+#   P16 case B11: ledger deleted while objects/ survives — LOUD refusal to
+#       re-baseline; the v2->v3 change is NOT absorbed as first-seen
+#   P17 allowlist symmetry: an allowlisted symlink whose TARGET is denied
+#       refuses (deny runs first, on both forms — precedence is not path
+#       agreement); a symlink to an ALLOWED target still captures (the fix
+#       must not close case C by breaking every symlinked path)
+#
+# Uses FAKE/STUB sources only (no live network). Isolated per test.
