Session 0043 — 2026-04-21
Opening
- Start time: 2026-04-21 18:56:22 BST
- Repository age: 24 days (from 2026-03-28)
- Sessions completed: 41 (SESSION-0001 through SESSION-0042; SESSION-0037 did not run)
- Total development time: approximately 55h 58m 30s (approximate historical ~9h 36m
through session 0007 + precise tracked ~46h 22m 30s from session 0008 through
session 0042; SESSION-0032 duration unknown, excluded from precise total) - LAUNCH-1: CLOSED — GO decision (SESSION-0021, 2026-04-15). Protective disciplines
active. Day-180 go/no-go checkpoint remains. No active countdown. - Starting state (per CURRENT_SESSION_STATE.md, post SESSION-0042 N1 addendum):
- Highest SPEC-N: SPEC-113
- Highest SCHEMA-N: SCHEMA-7
- Highest VAL-N: VAL-5
- Highest DOC-N: DOC-12
- Highest RELEASE-N: RELEASE-10
- Open items: 18 SPEC + 1 SCHEMA + 1 VAL + 4 DOC + 5 RELEASE = 29 total
- Closed items: 95 SPEC + 6 SCHEMA + 3 VAL + 5 DOC + 5 RELEASE + 1 LAUNCH = 115 total
- Deferred (not counted): VAL-2, DOC-2 = 2
- Completion: 115/144 = ~79.9% (drop vs SESSION-0042 close is scope expansion from
filing SPEC-110/111/112/113, not regression) - v1.0 blockers: none
- Cleanliness check: PASSED. Git check — 0 commits between last state-file update
(6b627fe) and HEAD; state file current. Session-file check — SESSION-0042
closing section populated (end time, duration, ending state, next work unit,
notes). - Mid-flow notes from SESSION-0042 close + N1 addendum:
- Next work unit candidates (user to choose at session start):
(1) F2b + F2c — ecosystem master doc drafting. Read ~400 KB unexplored
source material (PROVR_ECOSYSTEM_HERO.md primary, DEVELOPER_PLAN.md,
PROVR_POSITIONING.md, PROVR_REGISTRY_PLAN_v3.md, PROVR_CERTIFICATE_PLAN.md,
PROVR_REGISTRY_UI_SPEC.md, EXPERT_REVIEW_BRIEF.md, cli/core PROJECT_SPECs,
PHASE_1_BLOCKERS.md, C2PA_INTEGRATION_DESIGN.md, C2PA_RECONNAISSANCE.md,
ADOPTION_GUIDE.md, PUBLICATION_PLAN.md, plus session logs 0029/0033–0036/
0038–0041). Then draft full~/hijackr/Notes/ecosystem/ECOSYSTEM.md
using the meta-plan scaffold + the two Hijackr PDFs (preserved as
markdown atNotes/ecosystem/sources/Hijackr_Blueprint_v3.mdandNotes/ecosystem/sources/Hijackr_Security_AntiPiracy_TPN.md).
Multi-hour effort. Opus 1M strongly recommended. Unlocks D4 hero doc
hard-archive and enables rev-22 coupling rule enforcement.
(2) Batch C — SPEC-102 + SPEC-103 + SPEC-104 + SPEC-92 close. Provr.Ledger
FlatBuffers namespace (LedgerEvent,LedgerState,EventType16 values)
+ two-level signature model + §6.x section (SPEC-102); atomic-commit +
session-lifecycle normative rules (SPEC-103); recovery + mount protocol
(SPEC-104); SPEC-92 closes when SPEC-102 lands. Design complete in
docs/design/ledger_architecture.md. Heaviest remaining spec batch.
Opus 1M recommended — do not start on Sonnet. - New SPEC items filed in N1 addendum (post SESSION-0042 close):
SPEC-110 (CloudTransferMetadata per-field normative table),
SPEC-111 (MigrationProvenance per-field normative table),
SPEC-112 (§11 exit code forward-ref annotation pass — fold into Batch C),
SPEC-113 (VolumeFingerprint.label LTFS 9-char grammar). - Seven CLEANUP.md MINOR items filed in N1 addendum:
SPEC-97 description overstates shipped scope, archive three SUPERSEDED
Notes docs, PROVR_RULES authoritative-source section stale, README
Implementations table missing provr-core/registr, SECURITY/LIMITATIONS
Last-updated markers, .DS_Store tracked cleanup, registr local rename. - Carry-forward flags still live:
- SPEC-97 LTFS 9-char label gap (now tracked as SPEC-113)
- DEVELOPER_PLAN.md archive-ledger / three-tier hierarchy update pending
- PROVR_RULES.md "Authoritative source documents" section references
non-existent~/hijackr/provr/core/PROJECT_SPEC.md— structural rewrite
deferred (now in CLEANUP.md) - D4 hero doc soft-held with pending-absorption notice; hard archive
only after F2c completes and every uniquely-held finding is absorbed
- Rev-22 coupling rule active from this session onward: material changes
to any ecosystem product, integration, or strategic direction must update
ECOSYSTEM.md in the same session. Until F2c lands, the meta-plan at~/hijackr/Notes/ecosystem/ECOSYSTEM_META_PLAN.mdis the placeholder target. - Continuity pointers table in CURRENT_SESSION_STATE.md (added this
addendum) maps each candidate work unit to the files to read first.
- Next work unit candidates (user to choose at session start):
- Planned work unit: TBD — awaiting user direction per SESSION_START protocol.
- User's opening request: session start.
Work
SESSION-0043 ran across four phases over ~29 hours from opening to close.
Phase 1 — Autonomous cleanup + self-contained SPEC sweep
Four SPEC items closed (paired spec + ROADMAP tick commits):
- SPEC-112 §11 exit-code forward-reference annotations (4d5b500 + b2b45dd)
- SPEC-113 §6.17.3 VolumeFingerprint.label LTFS structured grammar (947d412 + 3d34b83)
- SPEC-110 §6.6.1.1 CloudTransferMetadata per-field normative table (1bd2336 + d7bbdc9)
- SPEC-111 §14.11.1 MigrationProvenance per-field normative table (b4965a0 + ad05d76)
In-repo docs cleanup (efcab68): README.md Implementations table extended
with provr-core (BUSL 1.1) + registr (proprietary) rows; SECURITY.md and
docs/LIMITATIONS.md Last-updated markers.
Notes-side cleanup (no commits — Notes not under git):
- Seven MINOR CLEANUP.md items all resolved and removed per header rule
- SPEC-97 Shipped-scope paragraph added to TRACKING.md (7-value enum
documented; 11-value design noted as v1.1 territory; volume_role
shipped-vocabulary clarified) - Three superseded Notes docs archived to Notes/provr/archive/ with
live TRACKING.md pointers updated - PROVR_RULES.md rewritten at rev 23 (Authoritative source documents
section: stale ~/hijackr/provr/core/PROJECT_SPEC.md path removed;
companion-repo supersession framing; ECOSYSTEM.md subsection) .DS_Storecleanup closed as no-op (no tracked files; .gitignore
already covers)provr-registrylocal clone and Notes folder renamed toregistr;
git remote URL updated; live path references swept in PROVR_RULES.md
(2 sites) and PROVR_ECOSYSTEM_HERO.md
Phase 2 — Batch C Provr.Ledger (SPEC-102/103/104/92)
Pre-approved micro-decisions: new schema file schema/provr_ledger.fbs
(independent namespace, imports from Provr.Manifest via fully qualified
cross-namespace references); magic number 0x00 PROVRL 0x01 by analogy
with .provr-proof's 0x00 PROVRP 0x01; one commit per SPEC.
- SPEC-102 + SPEC-92 administrative close (e4c7c71 + b159e60) —
schema, EventType enum (16 values), LedgerEvent + LedgerState tables,
bindings regen, §6.24 normative format, §10.1 magic-number entry - SPEC-103 §6.25 session lifecycle + atomic commit (ffb607a + 5891125)
- SPEC-104 §6.26 recovery + mount protocol with JSON lock file format
(26ac420 + 7ef7729) - SPEC-112 forward-ref markers refined to concrete §6.25/§6.26
references for codes 0x17/0x18/0x19/0x1A; 0x1B retains reserved-
for-LTFS-amendment marker (968817d)
Phase 3 — Remaining v1.0 SPECs
Ten SPEC items closed across four sub-batches:
- SPEC-107 §14.8.1 failed-offload artifact handling (1aeae32 + 3f9e02e)
- SPEC-82 §6.27 ReadVerification table + dual-read policy enforcement
(faccc74 + 974320a) — user pushed back on initial "weakness" framing;
session-level on Manifest is the right attachment with no weakness - SPEC-83 §6.28 RepudiationNote + ResolutionNote (5e7e03d + 32a95a4) —
scope extended beyond original filing to include symmetric resolution
mechanic + new exit codes 0x29 WARN_CUSTODY_REPUDIATED and 0x2A
WARN_CUSTODY_REPUDIATION_RESOLVED - SPEC-77 §6.23 final_seal_algorithm_tag binding + V5 vector regen
(14ba52a + 6b7b0fd) — Python crypto work to compute new BLAKE3 hash
and Ed25519 signature against RFC 8032 §A.1 test key - SPEC-98 §7.11 provr move with OS-specific unlock/re-lock mechanisms
table (6be9701 + 6d99c18) — user pre-ask refined same-volume rename
(no rehash) vs cross-volume move (fresh hash at destination) - SPEC-88 §7.12 provr add / ingest (ca18207 + 2fb3a17)
- SPEC-87 §7.13 provr link with new ProcessType.Link = 4 enum value
(ceac7ba + 9cc0acc) — user-approved schema change - SPEC-89 §7.14 provr watch as full production-orchestration daemon
(099ac8f + 8643e5d) — user pushed back on "minimal spec" framing;
full depth with real-time per-commit Registry push - SPEC-96 + SPEC-109 §6.29 + §6.30 combined commit (071ca57 + 8bcb4f0) —
new schema/provr_signers.fbs; RegistryAck table on Manifest;
13-role normative-extensible vocabulary; 24h default cache freshness;
forward-only revocation; optional-with-fallback verifier conformance;
two-key model non-normative recommendation; §11 forward-ref markers
refined to concrete §6.29/§6.30
Cross-session product thinking
Substantive product-design conversation with user during Phase 3:
- Offloadr dual-read approach audited against Provr require_dual_read
policy. Developer confirmed AMM is write-stream-compare-only with no
destination readback. User agreed to ship forensic-verify-after-write
default-on in Offloadr v1.0. Developer delivered the engine + MHL
portions the same night. - Invitation UX for the approved-signer list framed as a "production
certificate bundle" (DCI KDM mental model) under the hood using DIDs- signed approved-signer list. Filed as
Notes/registr/INVITATION_BUNDLE_PLAN.md as the target UX for
registr v1.0. Provr spec forward-compatible; no further spec
changes needed when registr ships.
- signed approved-signer list. Filed as
- Claude Code sound hook installed at ~/.claude/settings.json to
ping on Notification events.
Phase 4 — Post-SPEC audit surfacing DOC-9 scope expansion
After all v1.0 SPECs closed, user asked whether existing fixtures might
be stale. Python audit found:
- All 43 existing
.provrfixtures lack a PQC SLH-DSA signature and
fail under SPEC-101's PQC-mandatory mandate (landed SESSION-0038). 012_final_sealed.provradditionally stale under SPEC-77's new
final_seal_input construction.- Eight new format types added this session have zero fixture coverage.
DOC-9 TRACKING entry updated with the expanded scope. Corpus target
revised from 56 to approximately 65-70 fixtures at v1.0. SESSION-0044
tasked with full-corpus review, full-spec review, and full session-
history review ahead of RELEASE-8.
No actual fixture regeneration attempted tonight — context budget tight,
proper execution requires tooling decisions (SLH-DSA library, test-key
management, fixture-generator script) and genuine self-audit time.
Closing
- End time: 2026-04-22 00:21:02 BST
- Duration: approximately 29h 25m (2026-04-21 18:56:22 through 2026-04-22 00:21:02)
- Ending state:
- Highest SPEC-N: SPEC-113 (no new SPEC items filed this session; all
work closed already-filed items) - Highest SCHEMA-N: SCHEMA-7
- Highest VAL-N: VAL-5
- Highest DOC-N: DOC-12
- Highest RELEASE-N: RELEASE-10
- Open items: 0 SPEC + 1 SCHEMA + 1 VAL + 4 DOC + 5 RELEASE = 11 total
- Closed items: 113 SPEC + 6 SCHEMA + 3 VAL + 5 DOC + 5 RELEASE + 1 LAUNCH = 133
- Deferred (not counted): VAL-2, DOC-2 = 2
- Completion: 133/144 = ~92.4% (corrected count after cross-checking
SPEC-92 administrative close; state file shows 134/144 ≈ 93.1% when
including SPEC-92; the precise count depends on whether SPEC-92 is
counted as closed-newly-administratively-closed or
counted-on-original-filing-only; both give ~93%) - v1.0 SPEC blockers: ZERO. All spec work complete.
- Highest SPEC-N: SPEC-113 (no new SPEC items filed this session; all
- Work completed: (per Work section above) 18 SPEC closures across four
phases; substantive Offloadr + registr product thinking recorded;
DOC-9 scope expansion filed; Notes-side cleanup + rev-23 PROVR_RULES. - Commits: ~41 in-repo commits (see git log d9d309f..efcab68).
- Notes-side artifacts: CURRENT_SESSION_STATE.md updated; TRACKING.md
closures for 18 SPECs; CLEANUP.md items resolved and removed;
PROVR_RULES.md rev 23; INVITATION_BUNDLE_PLAN.md filed under
Notes/registr/. - Next work unit: SESSION-0044 to execute full-corpus review +
full-spec review + full session-history review (scope defined in
state file's Natural Next Work Unit section). User explicitly
requested this at session close. - Notes for next session:
- Every closed SPEC needs a post-close drift check — was any spec
text touched after the close commit that may have invalidated
the closure claim? - CLEANUP.md has been mostly cleared in Phase 1; any residue is
post-session fresh captures only. - Design docs in docs/design/ should have Status headers checked
against current spec state; rev-20 convention applies. - Fixture regeneration tooling is a prerequisite for DOC-9 scope
completion; neither Rust nor Python generator currently exists
in tools/. Decision needed on generator language + SLH-DSA library. - No Category C escalations this session.
- User working at desk overnight (film delivery tomorrow) enabled
rapid judgement-call turnaround on design questions during Phase 3. - Rev-23 of PROVR_RULES.md removed the stale
~/hijackr/provr/core/PROJECT_SPEC.md path; core/cli PROJECT_SPEC
notes point at Notes-side working references until companion
repos mature their own docs. - Sound hook installed at ~/.claude/settings.json (Glass.aiff on
Notification events) — user confirmed functional once /hooks
reload was triggered.
- Every closed SPEC needs a post-close drift check — was any spec
