Release object, release in hand and step 9.c option B (spec v0.15 draft)
The release of a round becomes a file, .dkr: a release object in
deterministic CBOR, {0: "datekeys-release", 1: 1, 2: chain_hash, 3: round,
4: signature}, which provider.EncodeRelease writes and DecodeRelease reads
with its layers (size, type and version, schema). provider.ParseRelease
also reads drand's JSON as the input of the caller. Verify checks the chain
hash a release names before its round and its signature, with
ERR_PROFILE_MISMATCH. provider.Archive reads a local release archive, the
informative format of the draft.
capsule.OpenOptions.Release takes a release in hand, a provider.Supplier,
exclusive with Source: Open does not compare it with the clock (step 9.c,
option B) and reports a clock behind it in Opened.ClockBehind; a network
source is still never asked before the round time. The CLI gains
decrypt -release FILE (.dkr, drand's JSON or a local archive),
decrypt -save-release FILE.dkr and the command release, which fetches,
verifies and saves the .dkr without opening the capsule.
Test data: vectors/release.json, releases/<round>.dkr for rounds 1000,
1001, 1004 and 2000, and a local archive of rounds 1000 to 1004. In
mutations.json every case says its source, "supplied" or "network"; the
case "round not reached yet", a release in hand, now opens, and four cases
are added: the same with a network source, a release of another round from
a network source, and two release objects of another chain. SpecVersion
stays 0.14 until the author approves the draft.

Spec v0.15 draft: remove the .dkr file
The author's decision of 7 October 2026. A release saved next to a capsule
cannot exist when the capsule is made, and once the date comes the capsule
can be opened: such a file only opens it again and does not cover the real
case, someone opening it decades later when drand is gone and nobody saved
anything. Long-term recovery rests instead on archives and cache services
that keep the releases of all rounds; a reader asks for its round and
verifies the signature against the pinned key.
Spec: the .dkr extension (section 20, back to v0.14), sections 1, 4, 8, 45,
47.1, 49, 50 (rewritten), 53, 62.1 (rule 28 removed, rule 26 reworded),
63, 70, 73, 74 (the datekeys.release .dkk extension dropped too), 76
(the v0.15 block, with the discarded design) and the annex 79. The
release object, the chain hash at step 10, step 9.c option B and the
archive format stay.
Code: decrypt -save-release and the command datekeys release are gone,
with writeRelease and their tests; decrypt -release FILE stays. The
release objects of testdata/releases are now <round>.cbor, and
TestVectorFilesAreCurrent fails on a file the generator no longer writes.

"description" : "The release object (spec v0.15, §47.1), and drand's JSON as the input of the caller, each checked against the pinned Quicknet profile and the round of a DateKey as step 10 of spec §63 checks a release that the caller supplies; and the lookups of a local release archive (spec v0.15, §50).

Release object, release in hand and step 9.c option B (spec v0.15 draft)
The release of a round becomes a file, .dkr: a release object in
deterministic CBOR, {0: "datekeys-release", 1: 1, 2: chain_hash, 3: round,
4: signature}, which provider.EncodeRelease writes and DecodeRelease reads
with its layers (size, type and version, schema). provider.ParseRelease
also reads drand's JSON as the input of the caller. Verify checks the chain
hash a release names before its round and its signature, with
ERR_PROFILE_MISMATCH. provider.Archive reads a local release archive, the
informative format of the draft.
capsule.OpenOptions.Release takes a release in hand, a provider.Supplier,
exclusive with Source: Open does not compare it with the clock (step 9.c,
option B) and reports a clock behind it in Opened.ClockBehind; a network
source is still never asked before the round time. The CLI gains
decrypt -release FILE (.dkr, drand's JSON or a local archive),
decrypt -save-release FILE.dkr and the command release, which fetches,
verifies and saves the .dkr without opening the capsule.
Test data: vectors/release.json, releases/<round>.dkr for rounds 1000,
1001, 1004 and 2000, and a local archive of rounds 1000 to 1004. In
mutations.json every case says its source, "supplied" or "network"; the
case "round not reached yet", a release in hand, now opens, and four cases
are added: the same with a network source, a release of another round from
a network source, and two release objects of another chain. SpecVersion
stays 0.14 until the author approves the draft.
