# Mosaic wake component — VERSION metadata manifest (Gate B).
|
|
#
|
|
# EPIC #892, W2 + W3 of the wake/heartbeat canon.
|
|
#
|
|
# SCOPE — THIS FILE IS VERSION METADATA ONLY. It declares the wake component's
|
|
# semantic version and the RANGE of watch-list schema versions it supports. It
|
|
# does NOT authorize file/path ownership: path-ownership remains the sole domain
|
|
# of packages/mosaic/framework/framework-manifest.txt (Gate A). Do not read any
|
|
# ownership meaning into this file.
|
|
#
|
|
# Format: KEY=VALUE, one per line. '#' and blank lines ignored.
|
|
|
|
# Component identity + semantic version.
|
|
# 0.1.0 W2 — store+drain lib + ack-wrapper.
|
|
# 0.2.0 W3 — cumulative-state digest renderer + non-circular HMAC signer.
|
|
# 0.3.0 W4 — per-host single-instance delta-gated detector daemon.
|
|
# 0.4.0 W5 — synthetic-canary FN-oracle + source-parity reconciler.
|
|
# 0.5.0 W6 — off-host dead-man beacon emitter + pluggable alarm-sink adapter
|
|
# + beacon-absence alarm (fail-loud on unconfigured/unreachable).
|
|
# 0.6.0 W7 — A10 idempotent, fail-closed component installer (Gate-A
|
|
# intersect+validate against the framework-manifest SSOT), the
|
|
# mosaic-wake.service detector daemon, the blank-reset retire idiom
|
|
# for the legacy heartbeat timer + snapshot-guard, and fail-closed
|
|
# alarm-target/HMAC-key install-validation. Also folds in the two W6
|
|
# monitor-integration observations (monitor-side ingested_ts
|
|
# staleness + beacon HMAC-verify at record).
|
|
# 0.6.1 #908 — UNIFY observed_seq on a SINGLE store-side allocator. store.sh
|
|
# enqueue is now the sole allocator (reads its own cursor, next=+1
|
|
# under an exclusive lock, prints the seq; commits IFF the durable
|
|
# write succeeds). The detector-private observed_seq_counter and its
|
|
# --seq hand-off are DELETED; the reconciler enumerates via the same
|
|
# store allocator (its dual-allocator fail-closed guard retired). This
|
|
# dissolves the three defects rooted in the private-counter seam:
|
|
# burn-before-enqueue (arrow 1), W5 co-feed aliasing (arrow 2), and
|
|
# the migration-restart silent-swallow (arrow 3, now structurally
|
|
# impossible — allocation is always > consumed or fails loud).
|
|
# 0.6.2 #914 digest.sh renderer fixes (live wake-pilot findings): (a) the
|
|
# embedded ack copy-run line now bakes an explicit
|
|
# WAKE_AGENT=<render-time-agent> prefix (shell-quoted) so an
|
|
# env-less copy-run resolves to the correct per-agent namespace
|
|
# instead of silently falling back to `default`; (b) the
|
|
# ORIENTATION locator renderer now also recognizes the locator
|
|
# vocabulary detector.sh (A1) actually emits for a digest-class
|
|
# entry (kind/id/observed_hash/remote/path), so a digest-class
|
|
# pointer carries a usable (soft) locator instead of rendering
|
|
# empty. Display-only: the ACTIONABLE-tier hard-locator FAIL-LOUD
|
|
# gate (_has_hard_locator, exit 4) is unchanged.
|
|
# 0.6.3 #912 digest.sh scrub PORTABILITY (no contract change): _scrub_ctrl's
|
|
# control/bidi/zero-width byte patterns are now LITERAL bytes (via
|
|
# printf %b) instead of GNU-sed `\xNN` hex escapes. BusyBox sed (the
|
|
# Alpine/musl CI runner, running as root) rejects a `\xNN` character
|
|
# range, which aborted the whole scrub sed and silently VOIDED the
|
|
# scrub in CI — collapsing every scrubbed value to empty and failing
|
|
# the digest suite's D1/D4/D5/D6 only in the Woodpecker runner. The
|
|
# scrub now renders byte-identically under GNU sed (glibc dev) and
|
|
# BusyBox sed (Alpine CI). The two-tier trust, exit-4 hard-locator
|
|
# FAIL-LOUD, and the secret-scrub/SHA-preservation contract are all
|
|
# unchanged — this makes the existing scrub deterministic across
|
|
# runners, it does not weaken it.
|
|
# 0.6.4 #920 digest.sh drain-quarantine + reconciler-enumeration render tier
|
|
# (live wake-pilot finding #6, BLOCKING). (a) PER-ENTRY
|
|
# QUARANTINE: a render-refused ACTIONABLE entry (no §2.1 hard
|
|
# locator) is now DEAD-LETTERED to $STATE_DIR/dead-letter.jsonl +
|
|
# a loud per-entry alarm and EXCLUDED, while the REST of the
|
|
# cumulative set still renders (exit 0). Replaces the whole-digest
|
|
# exit-4 that let ONE malformed entry wedge the entire drain (head-
|
|
# of-line blocking — 4 consecutive live timer failures, nothing
|
|
# delivered). Fail-loud is preserved, now per-entry; the bad entry
|
|
# is never silently dropped. (b) Reconciler ENUMERATIONS render
|
|
# ORIENTATION-tier: an entry whose locators carry reconciled==true
|
|
# (set only by reconcile.sh) is EXEMPT from the actionable hard-
|
|
# locator gate and renders as an orientation pointer via
|
|
# _locator_line's digest-class vocabulary — a RENDER-layer change
|
|
# only. reconcile.sh's STORE class is UNCHANGED (non-coalescing), so
|
|
# distinct enumerations never collapse (§2.3/T2/G3-R6 intact); the
|
|
# rejected class=digest alternative would have silently coalesced
|
|
# them. store.sh and reconcile.sh are UNCHANGED by 0.6.4.
|
|
# 0.6.5 #927 enqueue TOCTOU fix — move stale-tmp cleanup OFF the hot enqueue
|
|
# path (no concurrent in-flight-write clobber). cmd_enqueue called
|
|
# _wake_init_dir() (which reaped EVERY .wake.tmp.* unconditionally)
|
|
# BEFORE taking the enqueue lock, so a 2nd enqueue's PRE-LOCK cleanup
|
|
# deleted the LIVE in-flight tmp of a 1st enqueue holding the lock
|
|
# through its atomic write -> spurious "durable pending write FAILED"
|
|
# abort of a valid enqueue (reachable under live co-feed: detector +
|
|
# reconciler concurrently enqueue). FIX (_wake-common.sh): (a)
|
|
# _wake_init_dir no longer reaps tmps — it only ensures the layout,
|
|
# so nothing on the enqueue/consume/cursors/ack hot paths can clobber
|
|
# a concurrent live write; (b) _wake_clean_stale_tmp is AGE-SCOPED
|
|
# (mmin +${WAKE_TMP_STALE_MIN:-5}) so it can only remove demonstrably-
|
|
# orphaned crash-left tmps, never a live (ms-old) in-flight write.
|
|
# Reaping now runs as an explicit MAINTENANCE action at store.sh init
|
|
# (daemon-start) and the detector poll tick (detector.sh), keeping
|
|
# accumulation bounded once-per-pass instead of raced per-enqueue.
|
|
# #908 seq-integrity is UNCHANGED (single store-side allocator,
|
|
# atomic allocate+enqueue under flock, arrow-1 no-burn, anti-swallow
|
|
# fail-loud). reconcile.sh is UNCHANGED (its enumeration retry is the
|
|
# structural recovery net: an aborted enqueue advances neither the
|
|
# seen-ledger nor observed_seq, so the source is re-enumerated next
|
|
# cycle — no obligation loss). Files changed: _wake-common.sh,
|
|
# store.sh, detector.sh (+ tests).
|
|
# 0.6.6 #924 digest.sh dead-letter QUARANTINE alarm — G2a fix (wake-pilot
|
|
# cure-verification follow-up on #920/PR #922). The #920 per-entry
|
|
# quarantine alarm was stderr/journal-LOCAL only; a dead-lettered
|
|
# entry is STORE-ACCOUNTED (§2.3) so the reconciler never re-flags
|
|
# it, so journal-local-only visibility meant an unattended operator
|
|
# could PERMANENTLY MISS a real obligation (G2a silent-degradation).
|
|
# FIX: the SAME per-entry quarantine alarm now ALSO routes through
|
|
# WAKE_ALARM_SINK_CMD — REUSING beacon.sh's (W6/#910) exact
|
|
# pluggable off-host alarm-sink adapter contract (operator target
|
|
# resolved by-name inside the adapter, fail-closed) — IN ADDITION
|
|
# to (never instead of) the existing stderr diagnostic. Per-
|
|
# observed_seq DEDUP (entries carry no per-entry wake_id; the
|
|
# entry's durable identity is its store-allocated observed_seq,
|
|
# #908) via a durable alarmed-set file under STATE_DIR
|
|
# (dead-letter-alarmed.set, atomic-written) ensures a still-dead-
|
|
# lettered entry is alarmed off-host EXACTLY ONCE per drain/restart,
|
|
# never once per re-render; a NEW distinct dead-lettered entry
|
|
# still routes its own one alarm. An unconfigured/unreachable
|
|
# WAKE_ALARM_SINK_CMD is a LOUD per-entry stderr diagnostic
|
|
# (mirrors beacon.sh's fail-closed wording) but does NOT itself
|
|
# fail the whole render (per-entry fail-loud, never a whole-drain
|
|
# wedge — #920's core property is preserved). digest.sh is the
|
|
# ONLY file changed; store.sh/beacon.sh/reconcile.sh are
|
|
# UNCHANGED (beacon.sh's adapter contract is reused, not modified).
|
|
# 0.6.7 #913 wake-install.sh installer ADOPTION-GAP fixes (wake-pilot,
|
|
# non-blocking, ADDITIVE per #869). (a) DEP-CHECK: the installer
|
|
# sourced _lib/manifest.sh (the shared framework-manifest reader it
|
|
# needs for Gate A) unconditionally, so an older host seed that
|
|
# predates that helper aborted with a bare, obscure
|
|
# `source: No such file or directory`. It now checks the library
|
|
# FIRST and FAILS LOUD naming the missing file + the remedy (re-seed
|
|
# the framework, then retry --component wake) — the dependency is
|
|
# genuinely required (Gate A cannot be skipped on an enforcement
|
|
# path), so it fails loud rather than degrading. (b) SYSTEMD SEARCH
|
|
# PATH: wi_install copies mosaic-wake.service under mosaic home
|
|
# (systemd/user/, framework-owned) but `systemctl --user` searches
|
|
# ~/.config/systemd/user/, so the unit was invisible and could not be
|
|
# enabled/started. install now LINKS the unit into the user systemd
|
|
# search path (symlink -> the mosaic-home SSOT copy, so upgrades
|
|
# propagate) and VALIDATES it resolves (search-path entry exists,
|
|
# dereferences to a readable, well-formed unit; an opportunistic
|
|
# `systemctl --user cat` probe runs only behind a guard, since the
|
|
# installer may run where no user manager is live). Both steps are
|
|
# idempotent (a re-install neither duplicates nor breaks the link).
|
|
# #869 ADDITIVE: the link target lives OUTSIDE mosaic home, so it is
|
|
# not a framework-manifest path; ownership of the SSOT unit stays
|
|
# systemd/** in the single framework-manifest.txt authority — NO new
|
|
# owned path, NO second ownership authority. framework-manifest.txt,
|
|
# the install-ordering-guard, and the manifest parity contract are all
|
|
# UNCHANGED. Only wake-install.sh (+ test-wake-install.sh) changed.
|
|
# 0.6.8 #925 — framework-ship the canon-side FALLBACK WAKE (F7 replacement-
|
|
# before-retirement) so hosts get it OUT OF THE BOX rather than hand-
|
|
# wiring it per host. ADDITIVE, #869 / Gate-A/B discipline:
|
|
# (1) new framework units systemd/user/mosaic-wake-fallback.{timer,
|
|
# service}: a LOW-FREQUENCY SAFETY drain (oneshot service running the
|
|
# canon drain `digest.sh render --from-store`) fired by a per-class
|
|
# cadence timer, INDEPENDENT of the event-driven detector, so a stalled
|
|
# detector/daemon can never SILENTLY STARVE delivery. Both units are
|
|
# framework-owned via the EXISTING `systemd/**` glob in framework-
|
|
# manifest.txt (Gate A) — NO new owned path, NO second ownership
|
|
# authority. (2) an OPTIONAL, additive per-class `fallback_cadence`
|
|
# bound in wake-watch-list.schema.json (config, not code). It is
|
|
# backward-compatible within schema_version 1, so [schema_min,
|
|
# schema_max] stays [1,1] and the detector's Gate B range check is
|
|
# UNCHANGED (an out-of-range schema_version still fails loud). (3) A10
|
|
# install/wire: wi_install enumerates + LINKS + validates the two units
|
|
# into the user systemd search path (idempotent, fail-closed, same
|
|
# link-to-SSOT pattern as the detector unit); write-fallback-cadence
|
|
# writes the per-class cadence as a BLANK-RESET drop-in (exactly one
|
|
# effective OnUnitActiveUSec). (4) F7 install-validate: the §5 legacy
|
|
# reap now REFUSES unless the canon fallback wake is proven live
|
|
# (installed + schedulable floor always; enabled + proven-firing when a
|
|
# live user manager is probeable, mirroring #913's opportunistic
|
|
# WAKE_VERIFY_USE_SYSTEMCTL pattern) — F7 is encoded in the installer,
|
|
# not operator memory. framework-manifest.txt, the install-ordering-
|
|
# guard, and the manifest parity contract are all UNCHANGED.
|
|
# 0.6.9 #917 store.sh cmd_enqueue — HARDEN the final observed_seq cursor write
|
|
# (defense-in-depth, surfaced by the #915 review obs#2; non-blocking).
|
|
# The final cursor _atomic_write was the ONE durable write not wrapped
|
|
# in a failure check and was cross-file non-atomic with the observed.set
|
|
# write just before it. Now (a) the cursor write is GATED like the
|
|
# pending/observed.set writes (#908) — a cursor-write failure is
|
|
# FAIL-LOUD (non-zero + diagnostic), never silently swallowed into a
|
|
# spurious success while the allocation stayed uncommitted; and (b) on
|
|
# cursor-write failure observed.set is ROLLED BACK to its pre-write
|
|
# snapshot, so observed.set and the cursor can never be left cross-file
|
|
# inconsistent (observed.set ahead of a cursor that never committed) —
|
|
# they BOTH advance or NEITHER does. #908 is UNCHANGED: single store-side
|
|
# allocator, atomic allocate+enqueue under flock, arrow-1 no-burn
|
|
# (pending write still FIRST and its failure still aborts before any
|
|
# cursor advance), anti-swallow ≤consumed fail-loud, and the W2
|
|
# contiguous-prefix CONSUMED contract all intact. The cursor remains the
|
|
# sole COMMIT point (an uncommitted pending entry is re-derived/reconciled,
|
|
# never consumed), so a pending-ahead state is exactly the one #908 already
|
|
# tolerates on its observed.set-failure path. ON-DISK FORMAT UNCHANGED
|
|
# (read-compatible; a store written by older code reads identically). Only
|
|
# store.sh (+ test-wake-store-ack.sh T11) changed.

# Pieces shipped by this component version (informational):
|
|
# store.sh A2 — three-cursor durable store + drain lib. Stale-tmp reaping is
|
|
# OFF the hot enqueue path; `init` performs the age-scoped
|
|
# maintenance reap (#927). enqueue's final observed_seq cursor
|
|
# write is GATED fail-loud + rolls observed.set back on failure so
|
|
# the two never diverge (#917). (W2, #927, #917)
|
|
# ack.sh A4 — RECEIVED/CONSUMED ack-wrapper (local-write + ship). (W2)
|
|
# digest.sh A3 — cumulative-state digest renderer (hard locators,
|
|
# two-tier trust, injection/secret scrub). PER-ENTRY
|
|
# quarantine: a render-refused entry is dead-lettered +
|
|
# alarmed (stderr AND off-host via WAKE_ALARM_SINK_CMD,
|
|
# deduped by observed_seq, #924) + excluded, the rest still
|
|
# renders (no head-of-line block); reconciler enumerations
|
|
# (reconciled==true) render ORIENTATION-tier, gate-exempt.
|
|
# (W3, #920, #924)
|
|
# sign.sh A5 — non-circular HMAC signer (independent wake_id,
|
|
# load_credentials by-name; fills the hmac placeholder). (W3)
|
|
# detector.sh A1 — per-host single-instance delta-gated detector daemon
|
|
# (flock, anchor-scoped hashing, fail-loud source semantics;
|
|
# enqueues deltas to store.sh and captures the store-allocated
|
|
# observed_seq — no private counter, #908). Its poll tick also
|
|
# runs the age-scoped maintenance stale-tmp reap (#927). (W4)
|
|
# fn-oracle.sh A6 — synthetic-canary FN-oracle: injects a KNOWN delta at the
|
|
# source boundary, drives the pipeline through the detector's
|
|
# public poll-once, asserts CONSUMED within the per-class SLO
|
|
# (off-domain verdict from the terminal store cursor). §4
|
|
# requires FN-rate=0; a dropping/disabled detector FAILS. (W5)
|
|
# reconcile.sh A7 — source-parity reconciler: (i) source-coverage parity
|
|
# inventory (an omitted source cannot pass the vector
|
|
# vacuously) + (ii) periodic full reconcile to 0-unaccounted,
|
|
# enumerating pre-existing/startup state into the store via the
|
|
# SINGLE store-side allocator (co-feed is safe; the former
|
|
# dual-allocator fail-closed guard retired, #908). (W5)

# beacon.sh A8 — off-host DEAD-MAN liveness beacon: a monotonic beacon
|

# EMITTER (emit — the primitive the detector run-loop calls

|
# each cycle), the off-host monitor's RECEIVER + beacon-ABSENCE
|
|
# alarm (record, check), and a pluggable alarm-sink/beacon-sink
|
|
# ADAPTER INTERFACE. Liveness is SPLIT from work-triggering;
|
|
# the alarm fires on ABSENCE, routing to a human/other-host
|
|
# within its SLO (§4/G1). FAIL-CLOSED: an unconfigured OR
|
|
# unreachable target FAILS LOUD (no silent no-alarm host).
|
|
# A same-host sibling is REJECTED as non-independent; an

# wake-install.sh A10 — idempotent, fail-closed COMPONENT installer. Selects the

# single SSOT framework-manifest.txt (Gate A) — this VERSION
|
|
# manifest authorizes no path. Ships the blank-reset retire

|
# fail-closed alarm-target + HMAC-key install-validation (the
