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. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

v0.16: SpecVersion 0.16, the annex of the draft, and the tests in 76 SpecVersion is 0.16, and so is the spec field of every file of testdata, the frozen security_cms.json and locator.json included. annex/recovery.md is §79 of the draft v0.16, with the key of words in 79.7. The draft lists the two new fixtures in 67, says in 79 what recovery_check.sh opens, and names in 76 the tests that now exist. The CHANGELOG has its section.

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. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

"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). See testdata/README.md.",
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.

v0.16: drand's JSON is read strictly JSON of RFC 8259 in UTF-8 whose value is an object; no object repeats a name, and names are compared exactly once their escapes are decoded, so "round" is round and ROUND another name; an escape of a lone surrogate is malformed; round is a number without sign, fraction or exponent from 1 to 2^53 - 1; signature and randomness are strings (spec v0.16, 47.1). Go's encoding/json kept the last of two repeated names and matched ROUND to round. ParseDrandJSON, exported, is the one reader of drand's JSON: provider/drand reads the answers of the relays with it too.

v0.16: the escapes of the JSON vectors, restored The editor had written the escapes of the sources as their characters: the cases "round escaped as round" and "round twice, once escaped as round" of release.json had a plain round, and the surrogate pair of "a surrogate pair in a value" a plain emoji, so the shared vectors tested no escaped name.

They are escapes again, and the texts of words_test.go too, so that no mark or invisible character hides in the source. release.json gained 26 cases of drand's JSON, not 25 as b570338 says; the draft and the CHANGELOG now say 26.

v0.16: the escapes of the JSON vectors, restored The editor had written the escapes of the sources as their characters: the cases "round escaped as round" and "round twice, once escaped as round" of release.json had a plain round, and the surrogate pair of "a surrogate pair in a value" a plain emoji, so the shared vectors tested no escaped name. TestStrictJSON had lost its escaped é, its pair and the escape after a lone high surrogate. They are escapes again, and the texts of words_test.go too, so that no mark or invisible character hides in the source. release.json gained 26 cases of drand's JSON, not 25 as b570338 says; the draft and the CHANGELOG now say 26.

v0.16: drand's JSON is read strictly JSON of RFC 8259 in UTF-8 whose value is an object; no object repeats a name, and names are compared exactly once their escapes are decoded, so "round" is round and ROUND another name; an escape of a lone surrogate is malformed; round is a number without sign, fraction or exponent from 1 to 2^53 - 1; signature and randomness are strings (spec v0.16, 47.1). Go's encoding/json kept the last of two repeated names and matched ROUND to round. ParseDrandJSON, exported, is the one reader of drand's JSON: provider/drand reads the answers of the relays with it too. The error texts do not change. release.json gains 25 cases of drand's JSON for v0.16. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

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. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
