# digest.sh — A3 of the wake canon (EPIC #892, W3): the CUMULATIVE-STATE digest
# renderer with hard-locator enforcement, two-tier trust, and injection/secret
# scrubbing.
#
# CONTRACT ANCHORS (docs/scratchpads/heartbeat-planning/CONVERGED-DESIGN.md):
# §2.1 Digest schema — cumulative-state-since-last-CONSUMED, hard locators,
# two-tier trust, bounding/injection/secrets.
# §1.2/§2.3 the digest renders from the store's durable pending-inbox (the
# full unacked set since consumed_seq), coalesced.
#
# CUMULATIVE-STATE (§2.1): a digest is STATE SINCE THE LAST CONSUMED ACK, NOT an
# event delta. It renders the FULL unacked set (the durable inbox union since
# consumed_seq). Two changes that are both still pending both appear — a delta
# would silently drop the older one. Size scales with backlog; minimal when one
# item is pending.
#
# TWO-TIER TRUST (§2.1):
# ORIENTATION tier — self-sufficient, trusted-as-pointer: who / lane /
# board-head + the LIST of changed obligations (observed_seq + locators).
# Decides the ~80% no-op case with ZERO tool calls.
# ACTIONABLE tier — untrusted, must-revalidate: any fact that would authorize
# a consequential action (CI conclusion, mergeability, GO/hold, lease-state)
# is rendered ONLY as a CLAIM-TO-VERIFY, point-in-time-at-seq. Self-
# sufficiency NEVER exempts a consequential action from its live gate.
#
# HARD LOCATORS (§2.1): every actionable claim MUST carry a precise locator
# (repo + issue#, a 40-char SHA, or file:anchor) so re-verification is ONE
# targeted call. A missing locator = malformed ACTIONABLE entry = FAIL-LOUD.
#
# #920 (per-entry quarantine — fail-loud WITHOUT head-of-line blocking): a
# render-refused entry (actionable-tier, no hard locator) is QUARANTINED — durably
# DEAD-LETTERED to $STATE_DIR/dead-letter.jsonl + a LOUD per-entry alarm — and
# EXCLUDED from this drain, while the REST of the cumulative set still renders
# (exit 0). The bad entry is accounted-for (never silently dropped); it can no
# longer wedge the whole drain (the live pilot defect: one malformed entry
# exit-4'd the entire cumulative-state drain, delivering NOTHING).
#
# #924 (G2a fix — the #920 alarm was stderr/journal-LOCAL only): a dead-lettered
# obligation is STORE-ACCOUNTED (§2.3), so the reconciler NEVER re-flags it — a
# journal-local-only alarm means an unattended operator can PERMANENTLY MISS a
# real obligation (the exact G2a silent-degradation shape the canon exists to
# prevent). FIX: the per-entry quarantine alarm now ALSO routes through
# WAKE_ALARM_SINK_CMD — the SAME pluggable off-host alarm-sink adapter beacon.sh
# (W6/#910) uses: operator target resolved by-name inside the adapter, fail-
# closed (unconfigured OR unreachable => a LOUD diagnostic, never a silent
# no-alarm). The existing stderr diagnostic is KEPT (local + off-host, never
# either/or). Per-observed_seq DEDUP (the entry's durable identity — entries
# carry no per-entry wake_id; observed_seq is store.sh's sole-allocator
# monotonic id, #908) via a durable alarmed-set file under STATE_DIR ensures a
# still-dead-lettered entry is alarmed off-host EXACTLY ONCE, never once per
# re-render (the digest re-renders the cumulative unacked set every drain
# tick). A NEW distinct dead-lettered entry (a new observed_seq) still routes
# its own one alarm. See _dlq_route_alarm / _dlq_already_alarmed / _dlq_mark_alarmed.
#
# #920 (amended FIX 2 — reconciler enumerations are ORIENTATION-tier): a
# reconciler ENUMERATION carries locators.reconciled==true (set ONLY by
# reconcile.sh). Enumerations are self-orienting STATE-POINTERS, never
# consequential claims, so they are EXEMPT from the actionable hard-locator gate
# and render as ORIENTATION pointers via _locator_line's digest-class vocabulary
# (kind/id/observed_hash/path/…). Their STORE class is left UNCHANGED (non-
# coalescing) so distinct enumerations never collapse (§2.3/T2/G3-R6 intact).
#
# BOUNDING / INJECTION / SECRETS (§2.1): link-not-inline (pointers + bounded
# summary; raw diffs/logs stay at rest). Source free-text is NEVER instruction-
# adjacent: it is either omitted ("re-read at locator") or quoted inside a
# DELIMITED, length-capped, ANSI/bidi/zero-width-STRIPPED block framed as
# untrusted data. A secret-canary scrub runs over any inlined content. No
# secrets in digests. The W2 ack copy-run line is embedded verbatim.
#
# Operator-agnostic: state via XDG/env only; no operator paths/names/secrets.

Usage: digest.sh render [options]
Renders the CUMULATIVE-STATE digest (full unacked set since consumed_seq) from
the durable pending-inbox. Two-tier trust; hard-locator enforcement; scrubbed.
Options:
--from-store Read the pending set via store.sh drain (default).
--from-file FILE Read pending JSONL from FILE instead of the store.
--stdin Read pending JSONL from stdin instead of the store.
--lane LANE Orientation: the agent's lane (default: $WAKE_LANE).
--board-head SHA Orientation: current board-head SHA (default: none).
--agent A Orientation: who (default: $WAKE_AGENT or "default").
--wake-id ID wake_id to embed in the ack copy-run line.
--max-free-text N cap for a quoted untrusted block (default: 200 chars).
Exit codes:
0 digest rendered. Any render-refused ACTIONABLE entry (no §2.1 hard locator)
is QUARANTINED — DEAD-LETTERED to $STATE_DIR/dead-letter.jsonl + a loud
per-entry alarm (stderr AND off-host via WAKE_ALARM_SINK_CMD, deduped by
observed_seq, #924) — and EXCLUDED; the rest of the cumulative set still
renders (#920: fail-loud is per-entry, never a whole-drain wedge). An
unconfigured/unreachable WAKE_ALARM_SINK_CMD is itself a LOUD per-entry
diagnostic (#924/G2a) — it never wedges the whole render either.
Reconciler enumerations (locators.reconciled==true) render ORIENTATION-tier,
gate-exempt.
2 usage error.
3 jq is required but missing.
Environment:
WAKE_STATE_HOME override base state dir (XDG by default).
WAKE_AGENT per-agent queue namespace / identity.
WAKE_LANE default lane label.
WAKE_ALARM_SINK_CMD Pluggable off-host alarm route (SAME adapter beacon.sh/W6
uses) for the #920 dead-letter QUARANTINE alarm (#924).
Operator target resolved by-name inside the command.
Fail-closed: unconfigured or a non-zero exit is a LOUD
per-entry diagnostic (never a silent no-alarm host), but
does not itself fail the overall render (per-entry, not
whole-drain — mirrors the existing dead-letter-write
fail-loud-but-non-wedging behavior).

# #924 (G2a fix) — off-host dead-letter ALARM routing + per-observed_seq DEDUP.
#
# The #920 quarantine alarm was stderr/journal-LOCAL only. A dead-lettered entry
# is STORE-ACCOUNTED (§2.3) so the reconciler never re-flags it: journal-local
# visibility alone means an unattended operator can PERMANENTLY MISS a real
# obligation. FIX: route the SAME per-entry alarm through WAKE_ALARM_SINK_CMD —
# the pluggable off-host adapter beacon.sh (W6/#910) already defines (operator
# target resolved by-name inside the adapter command, fail-closed) — IN ADDITION
# to (never instead of) the existing stderr diagnostic.
#
# DEDUP: entries carry no per-entry wake_id (that field is the per-RENDER ack
# copy-run id minted by sign.sh); the entry's durable identity is its
# observed_seq (store.sh's sole monotonic allocator, #908 — stable for the life
# of the entry). A durable alarmed-set file under STATE_DIR (one observed_seq
# per line, atomic-written) records which observed_seqs have already been
# routed off-host, so a still-dead-lettered entry re-drained every timer tick —
# or across a process restart, since the marker is durable, not in-memory — is
# alarmed off-host EXACTLY ONCE. A NEW distinct dead-lettered entry (a new
# observed_seq) is not in the set, so it still routes its own one alarm.
