# 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).

# The #920 quarantine alarm was stderr/journal-LOCAL only. A dead-lettered entry

# visibility alone means an unattended operator can PERMANENTLY MISS a real

|
|
#
|
|
# DEDUP: entries carry no per-entry wake_id (that field is the per-RENDER ack

|
|
