Builds on the merged W2 store/ack (EPIC #892). Adds A3 (digest.sh) and A5 (sign.sh) under packages/mosaic/framework/tools/wake/, honoring CONVERGED-DESIGN. A3 — digest.sh (cumulative-state digest renderer), §2.1: - CUMULATIVE-STATE: renders the FULL unacked set since consumed_seq from the durable pending-inbox (state-since-CONSUMED, not an event delta). - TWO-TIER TRUST: orientation tier (who/lane/board-head + changed-obligation list with observed_seq + locators) decides the no-op case with ZERO tool calls; actionable tier renders every consequential fact ONLY as a CLAIM-TO-VERIFY, point-in-time-at-seq — never auto-actioned. - HARD LOCATORS: every actionable claim must carry repo+issue#/40-char SHA/ file:anchor; a missing locator is fail-loud (exit 4, nothing emitted). - BOUNDING/INJECTION/SECRETS: source free-text is quoted only inside a delimited, length-capped, ANSI/bidi/zero-width-stripped untrusted block; secret-canary redaction over any inlined content; embeds the W2 ack line. A5 — sign.sh (non-circular HMAC signer), §2.5: - wake_id generated INDEPENDENTLY at emit (not derived from, and not a member of, the signed field-tuple); wake_mac = HMAC(key, wake_id || agent_identity || mission_generation || observed_seq || emit_ts || content_hash) — over wake_id PLUS the fields, genuinely non-circular (the MAC is never its own input). Fills the `hmac` placeholder W2 left in store entries. - Key resolved BY NAME from the credential store, never inlined, never echoed; no flag accepts key material. Same-uid threat boundary documented; off-uid signer named as a future gate. RED-FIRST tests (test-wake-digest-hmac.sh, wired into test:framework-shell): cumulative-state, hard-locator fail-loud, two-tier (zero-call orientation + claim-to-verify), scrub (secret-canary + ANSI/bidi/zero-width), non-circular HMAC (independent wake_id + tamper-breaks-MAC), key-by-name-never-inline. Each verified to go RED on a targeted regression. shellcheck clean; operator-agnostic (XDG/env only). manifest.txt bumped to 0.2.0.

# 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 digest = FAIL-LOUD (non-zero
|
||||
# exit, NOTHING emitted) — never a silent send.
|
||||
#
|
||||
# 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.

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.
|
||||
4 FAIL-LOUD: an actionable claim carried no hard locator (malformed digest).

Environment:
|
||||
WAKE_STATE_HOME override base state dir (XDG by default).

|

# §2.5 Integrity — non-circular HMAC tuple + stated threat boundary.
|

# §1.2 three-cursor entries carry an `hmac` field (W2 left it a placeholder).
|

#
|
||||
# NON-CIRCULAR CONSTRUCTION (§2.5), verbatim intent:
|
||||
# - `wake_id` is generated INDEPENDENTLY: a fresh unique id at emit. It is NOT
|
||||
# derived from, and does NOT appear inside, the signed field-tuple. It is
|
||||
# prepended to the MAC input to BIND it to its payload — never self-referenced.
|
||||
# - wake_mac = HMAC(key, wake_id || agent_identity || mission_generation ||
|
||||
# observed_seq || emit_ts || content_hash)
|
||||
# The MAC is computed OVER wake_id PLUS the field-tuple. The value whose
|
||||
# authenticity the MAC establishes (wake_mac itself) is NEVER an input to its
|
||||
# own computation — that is what makes this genuinely non-circular.
|
||||
#
|
||||
# Rendered envelope makes the split explicit:
|
||||
# { wake_id, # independent id, prepended to MAC input
|
||||
# signed:{ agent_identity, mission_generation, observed_seq, emit_ts,
|
||||
# content_hash }, # the signed field-tuple (no wake_id, no mac)
|
||||
# wake_mac } # HMAC over wake_id || signed-tuple
|
||||
#
|
||||
# KEY HANDLING (§2.5): the key is resolved BY NAME from the operator credential
|
||||
# store (the same store `load_credentials` reads), NEVER passed inline, NEVER
|
||||
# echoed, NEVER placed in a unit, digest, or ledger. This tool exposes NO flag
|
||||
# that accepts key material — only a key NAME.
|
||||
#
|
||||
# THREAT BOUNDARY, STATED HONESTLY (§2.5, §7.3): this is a SAME-UID signer. A
|
||||
# same-uid attacker can read the credential file directly (and can observe the
|
||||
# key in `openssl`'s argv while a MAC is computed) — so a same-uid compromise is
|
||||
# OUT OF SCOPE for this tool. Closing it requires an OFF-UID signer (a separate
|
||||
# privilege-separated process), which is tracked as a §4 G6 gate, NOT silently
|
||||
# assumed away here.
|
||||

Commands:

sign [field opts] Emit a signed wake ENVELOPE (JSON) over an
|
||||
independently-generated wake_id + the field-tuple.
|
||||
verify Read an envelope on stdin; recompute and compare
|
||||
its wake_mac. Exit 0 = authentic, 1 = tampered.
|
||||
sign-entry [field opts] Read a durable store entry (hmac:"") on stdin;
|
||||
fill its `hmac` with wake_mac + add `wake_id`.
|
||||
verify-entry Read a signed entry on stdin; recompute and
|
||||
compare its `hmac`. Exit 0/1.
|
||||
sign-digest [field opts] Read rendered digest TEXT on stdin; hash it into
|
||||
content_hash and emit a signed envelope.
|
||||
|
||||
Field options (all optional unless noted):
|
||||
--key-name NAME credential-store key NAME to sign with (never the key
|
||||
itself). Default: $WAKE_HMAC_KEY_NAME or "default".
|
||||
--agent A agent_identity (default: $WAKE_AGENT or "default").
|
||||
--mission-generation G (default: $WAKE_MISSION_GENERATION or 0).
|
||||
--observed-seq N observed_seq (required for `sign`; taken from the entry
|
||||
for sign-entry/verify-entry).
|
||||
--emit-ts T epoch seconds (default: now, or the entry's emit_ts).
|
||||
--content-hash H precomputed sha256 of the wake content.
|
||||
--content STR content to hash into content_hash (use "-" to read stdin).
|
||||
--wake-id ID override the independent wake_id (default: fresh random).
|
||||
|
||||
Environment:
|
||||
WAKE_HMAC_KEY_NAME default credential-store key name.

||||
WAKE_AGENT agent identity / per-agent namespace.

# test-wake-digest-hmac.sh — RED-FIRST invariant harness for W3 (EPIC #892):

# the cumulative-state digest renderer (digest.sh, A3) + the non-circular HMAC
|
||||
# signer (sign.sh, A5).
|
||||
#
|

# Each test asserts ONE CONVERGED-DESIGN invariant and is designed to go RED if
|
||||
# that invariant regresses:
|
||||
# D1 CUMULATIVE-STATE: two still-pending changes both render (not just the
|
||||
# latest delta) — a delta would silently drop the older change. (§2.1)
|
||||
# D2 HARD-LOCATOR enforcement: an actionable claim with no precise locator
|
||||
# FAILS LOUD (non-zero exit, nothing emitted). (§2.1)
|
||||
# D3 TWO-TIER trust: orientation decides the no-op case with ZERO tool calls;
|
||||
# an actionable fact is a CLAIM-TO-VERIFY, never auto-actioned. (§2.1)
|
||||
# D4 SCRUB: a secret-canary + ANSI/bidi/zero-width in SOURCE free-text is
|
||||
# stripped/neutralized in the rendered digest. (§2.1)
|
||||
# H1 NON-CIRCULAR HMAC: wake_id is NOT a member of the signed field-tuple and
|
||||
# is independently generated; wake_mac is not its own input; tampering ANY
|
||||
# signed field (or wake_id) breaks the MAC. (§2.5)
|
||||
# H2 KEY BY-NAME, NEVER INLINE: the key is resolved by NAME from the credential
|
||||
# store; no flag accepts key material; the key never leaks into output; the
|
||||
# same-uid threat boundary is documented. (§2.5)
