Session 0042 — 2026-04-17

Opening

Start time: 2026-04-17 10:06:42 BST
Repository age: 20 days (from 2026-03-28)
Sessions completed: 40 (SESSION-0001 through SESSION-0041; SESSION-0037 did not run)
Total development time: approximately 51h 24m 32s (approximate historical ~9h 36m
through session 0007 + precise tracked ~41h 48m 32s from session 0008 through
session 0041; 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.
Starting state:
- Highest SPEC-N: SPEC-109
- Highest SCHEMA-N: SCHEMA-7
- Highest VAL-N: VAL-5
- Highest DOC-N: DOC-11
- Highest RELEASE-N: RELEASE-10
- Open items: 14 SPEC + 1 SCHEMA + 1 VAL + 4 DOC + 5 RELEASE = 25 total
- Closed items: 116
- Completion: 116/141 = ~82.3%
- v1.0 blockers: none
Cleanliness check: PASSED. Git check — 0 commits between last state-file update
(544b305) and HEAD; state file current. Session-file check — SESSION-0041
closing section populated.
Mid-flow notes from SESSION-0041:
- Batch C (SPEC-102 / SPEC-103 / SPEC-104) remains the highest-priority
  remaining batch and the largest; carry-forward unchanged from SESSION-0040.
  Heaviest remaining batch; requires Opus 1M for the cross-referencing. Do not
  start on Sonnet. Design complete in docs/design/ledger_architecture.md.
- SPEC-107 (failed-offload artifact handling) depends on SPEC-102 and is a
  natural follow-on to Batch C — schedule directly after.
- SPEC-109 (trust framework) depends on SPEC-96 (Batch G); spec-side work,
  Registry-side product workflow tracked separately in
  ~/hijackr/Notes/provr-registry/ per the cross-repo content scope rule.
- SPEC-97 LTFS label (9-char normative format) still not implemented —
  carry-forward from SESSION-0039.
- DEVELOPER_PLAN.md still needs archive ledger / three-tier hierarchy update
  — carry-forward from SESSION-0033.
- PROVR_RULES.md "Authoritative source documents" section needs a structural
  review: PROJECT_SPEC.md path is stale; provr-core has been carved out to its
  own repo; rule should reflect the actual location of core engineering docs
  (likely now in ~/hijackr/provr-core/ or ~/hijackr/Notes/provr-core/).
  Pre-existing finding flagged in SESSION-0041 but out of scope for wrap-up.
- SPEC-101 through SPEC-105 are not in ROADMAP.md (a backlog from earlier
  sessions). Small ROADMAP cleanup pass would close this.
- Companion-repo rename: provr-registry → registr performed in
  SESSION-0041; any provr-side documentation that referenced provr-registry
  by name should be checked.
Planned work unit: Batch C — SPEC-102 + SPEC-103 + SPEC-104 + SPEC-92 close
(from CURRENT_SESSION_STATE.md Natural Next Work Unit).
User's opening request: audit triage across two overnight audit files
(AUDIT-2026-04-17.md 37 findings + AUDIT-2026-04-17-PART2.md 42 findings),
plus four decisions (PDF replacement with OVERVIEW.md, hero doc fate,
bindings canonicalisation, design-docs rev-18 scan), plus ecosystem
master-doc meta-plan and drift-prevention rules.

Work

Eleven clusters executed:

M1 — Tracking drift fixes (Notes-side, no commit). 8 closed-but-Open
SPEC items corrected: SPEC-85, 86, 90, 91, 93, 95, 97, 99 (hashes
d378b70, e41240b, 12bb042, 53124e0, 24d7228, 12bb042 verified on main).
DOC-11 full entry backfilled (previously missing — rev-7 capture
discipline violation). SPEC-92 description rewritten to SPEC-102
supersession framing. Pre-SESSION-0033 hash disclaimer added at top
of TRACKING.md (option (a) per user — full re-anchor skipped;
disclaimer sufficient for the Notes-side convenience use case).
PROVR_RULES.md rev 19 amendment applied: Notes-side latitude
clause — TRACKING.md and session artefacts may carry cross-repo
coordination, business context, strategic rationale, operational
obligations; in-repo cleanliness rule unchanged.
M2 — ROADMAP backfill (commit 6161791). SPEC-101/102/103/104/105
rows inserted between SPEC-100 and SPEC-106; SPEC-107 inserted
between SPEC-106 and SPEC-108; SPEC-109 appended after SPEC-108.
SPEC-92 line rewritten to describe supersession by SPEC-102.
M3 — Spec §11 path corrections (commit d6afb42). Exit code 0x17
reference updated from /provr/scopes/ to PROVR-{drive-code}/ per
§14.1. Exit code 0x1A lock-file path updated from
/provr/ledger.provr-state.lock to {drive-code}.provr.ledger.lock
per §14.2. §6.4 intro cross-reference tightened from (§6.7) to
(§6.7.0). Three edits; one commit.
M4 — Orphan Cargo.lock removed locally. File existed on disk only;
was never tracked in git (covered by .gitignore). Deleted from working
tree with rm. No commit.
M5 — DOC count reconciliation (staged for Gate 4).
CURRENT_SESSION_STATE.md Open/Closed table, deferred-note, and
summary line updated. DOC-2 reclassified as deferred-uncounted
following VAL-2 convention. Phantom DOC-4/5 slots (never actually
existed) removed from the range descriptor. Completion recomputed
from 117/142 to 114/138 (then to 115/140 after DOC-12 filing).
D1 — Bindings canonicalisation (commit c7e39da). schema/generated/
declared canonical. Legacy bindings/ tree removed from git (77 files,
17866 lines). build/flatc-verify/ and build/flatc-verify-postcheck/
deleted locally (both were .gitignored). BUILD.md "Canonical binding
locations" section rewritten; Rust-specific cp mirror commands
dropped; regeneration commands unified on schema/generated/;
TypeScript noted as not currently shipped with future-regeneration
instructions. schema/generated/README.md simplified to defer to
BUILD.md. BUILD.md line 81 conformance example path corrected
(conformance/known-good/ → conformance/fixtures/).
F1 — Drift-prevention coupling rules (PROVR_RULES rev 20). New
section added: comprehensive coupling map across schema, spec,
tracking, conformance, build, public-facing docs, Notes-side, and
session lifecycle. Retroactive sweep rule: when a trigger touches
its listed dependents, drift found is fixed in the same session.
Design-doc Status header convention formalised (three states:
Design draft / Implemented / Superseded).
Rev-21 token conservation relaxation. Rule amended for Claude
Max 1M context. Full-file reads of spec/TRACKING/large Notes files
are acceptable when cross-section context is needed. Targeted
grep-and-view remains the preferred first pass.
D2 — Design docs rev-18 content scan (commit 5b0bcb8). Product
UI mockups stripped from docs/design/production_metadata.md (§7
viewer header, §8 certificate header), docs/design/volume_naming.md
(§7 Offloadr UX, §10 stale meta-content). Registry-UI sentence
rephrased to tool-neutral in docs/design/naming_conventions.md.
Offloadr/product attributions generalised in volume_naming.md.
Title "SPEC-97 v2" renamed to "Volume naming convention design".
All four design doc Status headers updated per the rev-20
convention. Three Notes-side content-preservation extracts written
before strip: Notes/offloadr/viewer_product_notes.md,
Notes/offloadr/volume_naming_ux.md,
Notes/provr-registry/certificate_metadata_mapping.md. Diff: 4 files,
30 insertions, 246 deletions.
D3 — OVERVIEW.md + PDF fate (commit 0e761ba). docs/OVERVIEW.md
written as the canonical format-only public overview (6 KB, rev-18
compliant, PQC posture corrected to reflect SPEC-101 mandatory-
at-all-levels). docs/Provr_Media_Manifest_v1.0_Overview.pdf
deleted. Full PDF prose preserved at Notes/provr/whitepaper_v1.md
with staleness annotations on every affected section (PQC framing,
CLI command list, Registry product content, BUSL licensing language,
corporate name references).
DOC-12 filed (commit 736b8e1). New tracked item for future
public docs/WHITEPAPER.md drafting. Full TRACKING.md entry added.
ROADMAP.md "Industry Engagement" row inserted. State file counts
updated: DOC open 3 → 4, highest DOC-N 11 → 12, completion
114/139 → 115/140.
F2a — Ecosystem master-doc meta-plan. Folder
~/hijackr/Notes/ecosystem/ created. Scaffolding file
ECOSYSTEM_META_PLAN.md written: purpose, location, scope (D —
comprehensive), ecosystem inventory, 15-section TOC, source inventory,
update cadence, relationships to other docs, brand-vs-spec-role
handling, drafting approach for F2b/F2c, open questions for user,
success criteria. Two Hijackr PDFs logged as source material:
Hijackr_Blueprint_v3.pdf (Hub & Spoke business/infrastructure) and
Hijackr_Security_AntiPiracy_TPN.pdf (threat model, Xcode hardening,
licence architecture, TPN Silver/Gold readiness). Ecosystem scope
clarified: prepr excluded, hijackr is the Hub at
hijackr.io + app.hijackr.io.
Rev-22 — ECOSYSTEM.md as live authority. PROVR_RULES amended:
new subsection in drift-prevention section declares
Notes/ecosystem/ECOSYSTEM.md the authoritative single source for
Hijackr dev state; coupling rule added for material product or
strategic changes to update the doc in the same session.
D4 — Hero doc soft-hold. Prominent header inserted at top of
Notes/provr/PROVR_ECOSYSTEM_HERO.md: partial-scope flag, specific
stale content flags (PQC framing, §14 exit codes, /provr/scopes/
paths, §15.5 descriptions), rev-18 scope violations noted, full
replacement map (design docs, OVERVIEW.md, whitepaper_v1.md,
Notes/provr-registry, Notes/offloadr, forthcoming ECOSYSTEM.md).
Hard archive gated on F2c completion. Original metadata preserved.

Commits on main (6):

6161791 chore(docs): backfill SPEC-101–105, SPEC-107, SPEC-109 in ROADMAP; update SPEC-92 line to reflect supersession
d6afb42 fix(spec): §11 exit code paths aligned to §14 layout; §6.4 cross-reference precision
c7e39da chore(build): consolidate FlatBuffers bindings under schema/generated/; remove bindings/ tree
5b0bcb8 chore(docs): rev-18 content scope pass on docs/design/; update Status headers to implemented/design-draft convention
0e761ba docs: add OVERVIEW.md replacing stale whitepaper PDF
736b8e1 chore(docs): add public whitepaper row to ROADMAP Industry Engagement (DOC-12)

PROVR_RULES.md amendments (4, Notes-side, no commits):

rev 19: Notes-side latitude (TRACKING.md et al. may carry cross-repo/
business content; in-repo cleanliness unchanged)
rev 20: Drift-prevention coupling rules (trigger → dependent map;
retroactive sweep; design-doc Status header convention)
rev 21: Token conservation relaxed for Claude Max 1M context
rev 22: Master ecosystem document as live authority
(Notes/ecosystem/ECOSYSTEM.md)

New tracked items:

DOC-12 filed (public Provr whitepaper at docs/WHITEPAPER.md)

Category C escalations: none.

User redirections / protocol changes:

User pulled F1 forward (drift-prevention rules) mid-session after
D1 completion.
User requested rev-21 token conservation relaxation for Claude Max
mid-session.
User asked for DOC-12 whitepaper task to be formally filed rather
than left as a Notes-side mention.
User expanded F2 scope: meta-plan alone insufficient; full
ECOSYSTEM.md drafting added as F2b (reading pass) + F2c (drafting)
deferred to a dedicated session.
User clarified ecosystem scope: prepr excluded; hijackr
confirmed as the Hub.

Notes-side extracts created during D2:

~/hijackr/Notes/offloadr/viewer_product_notes.md
~/hijackr/Notes/offloadr/volume_naming_ux.md
~/hijackr/Notes/provr-registry/certificate_metadata_mapping.md

Notes-side preservation file created during D3:

~/hijackr/Notes/provr/whitepaper_v1.md (full PDF prose with
staleness annotations)

Ecosystem scaffolding created during F2a:

~/hijackr/Notes/ecosystem/ECOSYSTEM_META_PLAN.md

Work completed: (per Work section above) audit triage across 79
findings, 11 clusters executed, 6 repo commits, 4 PROVR_RULES
amendments (rev 19-22), ecosystem master-doc meta-plan scaffolded,
DOC-12 filed.
Next work unit: two candidates —
(1) F2b + F2c — ecosystem master doc drafting (read unexplored Notes
sources, then draft the full ~/hijackr/Notes/ecosystem/ECOSYSTEM.md
populated with everything). Opus 1M strongly recommended. Multi-hour
dedicated session. Unlocks D4 hero doc hard-archive.

(2) Batch C — SPEC-102/103/104/92 close (Provr.Ledger FlatBuffers
namespace and normative spec sections). Heaviest remaining spec
batch. Opus 1M recommended.

User to choose at next session start.
Notes for next session:
- F2b inventory: files to read before F2c drafting include
  PROVR_ECOSYSTEM_HERO.md (76 KB — primary absorption source),
  DEVELOPER_PLAN.md (31 KB), PROVR_POSITIONING.md (19 KB),
  PROVR_REGISTRY_PLAN_v3.md (27 KB), PROVR_CERTIFICATE_PLAN.md
  (32 KB), PROVR_REGISTRY_UI_SPEC.md (47 KB),
  EXPERT_REVIEW_BRIEF.md (36 KB), cli_PROJECT_SPEC.md (33 KB),
  core_PROJECT_SPEC.md (35 KB), implementation/PHASE_1_BLOCKERS.md
  (16 KB), C2PA_INTEGRATION_DESIGN.md (25 KB),
  C2PA_RECONNAISSANCE.md (33 KB), ADOPTION_GUIDE.md (3.3 KB),
  PUBLICATION_PLAN.md (3.6 KB), plus mine relevant session logs
  (0029, 0033, 0034, 0035, 0036, 0038–0041). Approx 400 KB total.
- Two Hijackr PDFs (Blueprint v3, Security/TPN v1.0) are now
  authoritative source for Hub business/infrastructure and
  security posture. Open question from F2a meta-plan: where
  should these PDFs live permanently — Notes/ecosystem/sources/
  or a new Notes/hijackr/ folder? User to decide.
- Notes/hijackr/ folder not yet created; may be needed when
  Hub-side content accumulates beyond the two PDFs.
- Carry-forward flags from SESSION-0041: Batch C primacy (SPEC-102/
  103/104/92) — still next spec batch; SPEC-97 LTFS 9-char label gap
  remains unimplemented; DEVELOPER_PLAN.md archive-ledger / three-tier
  hierarchy update still pending; PROVR_RULES.md "Authoritative source
  documents" section still references non-existent
  ~/hijackr/provr/core/PROJECT_SPEC.md (pre-existing from rev-18
  carve-out; structural rewrite deferred).
- D4 hero doc is soft-held with pending-absorption notice. Hard
  archive only after F2c completes and every uniquely-held finding
  has been absorbed into ECOSYSTEM.md. Confirmed during SESSION-0042
  that this discipline holds.
- DOC-2 is now formally deferred-not-counted (per VAL-2 pattern).
  When the publication strategy lands, DOC-2 becomes reactivatable.
- Rev-22 coupling rule takes effect from SESSION-0043 onward:
  material changes to any ecosystem product, integration, or
  strategic direction update ECOSYSTEM.md in the same session.
  Until F2c completes, the meta-plan at
  ~/hijackr/Notes/ecosystem/ECOSYSTEM_META_PLAN.md is the
  placeholder target for "ecosystem changes happening during
  sessions".
- No Category C escalations this session. No pre-existing
  staleness found beyond what was already flagged in SESSION-0041
  continuity notes.
- Session-caused staleness check: no changes to
  DEVELOPER_PLAN.md / CORE_ENGINEERING.md / ROADMAP.md that
  introduce new cross-doc drift beyond what the rev-20 coupling
  sweeps already caught.
